[0041] The present disclosure provides a method for customizing a USB recording function according to a first embodiment. Referring to FIG. 2, FIG. 2 shows a flow chart of the method for customizing the USB recording function according to the first embodiment of the present disclosure. The method for customizing the USB recording function includes:
S10, judging whether the USB recording function corresponding to a program cache instruction is in an open state, on condition that the program cache instruction is acquired.

[0042] As the capacity and speed of hard disk are continuously improving with the development of hard disk technology, people prefers the Personal Video Recording (PVR) technology based on the hard disk, which contributed the generating of the USB recording technology. The time shifting is regarded as one major feature of the USB recording function. In detail, when the digital TV is turned on, the displayed programs can be recorded in real time, and the buffer area can be used for recording the programs for several hours. Users can pause the television program which is shown, then continue the displaying of the programs from pause point through the cache technique, as if the time had moved. The USB recording technology takes the hard disk as the storage medium, establishes local mass buffer area and huge program storage library, and controls and manages the programs through the digital processing technology. As such, the USB recording technology has the characteristics of large-capacity hard disk, digital, and fast access.

[0043] Under such circumstance, the USB recording function has now been commonly applied to TVs. However, after investigation, it is found that a large number of users may not actually use the USB recording function at all due to the viewing habits and viewing needs. But a patent fee should be payed for the TVs adopting the PVR technology. Therefore, the problem now is that many users who does not use the PVR technology at all should pay the patent fee to the digital TV manufacturers, which adds an unnecessary charging item to some consumers. For solving this problem, it is hoped that user can customize the USB recording function and activate the USB recording function when needed. The present disclosure mainly provides a method for user customizing the USB recording function. User decrypt the USB recording function of the TV by putting the encrypted key of the TV end on the website and acquiring the decryption code through a specific algorithm. After the USB recording function is decrypted, the company could pay the required patent fees and the like. Users do not need to pay the corresponding patent fees for PVR function again.

[0044] The Personal Video recorder (PVR) is regarded as a Video Cassette Recorder (VCR) which does not need to be equipped with a video tape. The normal VCR records TV programs to Video Home System (VHS) video tape, while the PVR adopts a built-in hard disk drive rather than the video tapes. After recording TV programs to the built-in hard disk, the recorded programs can be played at any time, can be fast-forwarded during viewing, and can be deleted when the programs are no longer required. The PVR can also update the program viewing guide. Through the program viewing guide, user can browse all the programs to be played in the next week, and can only record programs with certain keyword through programming the program viewing guide. The retrieval function of PVR is far from limited to retrieval of program name. PVR can also retrieve actors, directors, genres, etc.

[0045] Since the USB recording function is encapsulated during the TV production, user should activate the USB recording function when user needs to use the function for the first time. When user needs to use the USB recording function, user can trigger the USB recording function through a remote controller or other means, for sending out a program cache instruction. When receiving the program cache instruction, the TV end judges whether the user has successfully activated the USB recording function, if not, the TV end is configured to enter a program for activating the USB function.

[0046] S20, if the USB recording function is in an un-open state, acquiring a first request key and obtaining a first activation key based on the first request key.

[0047] If the user has not successfully activated the USB recording function, it means that the USB recording function is in an unopened state. When the program cache instruction is received, the first request key stored in the memory is obtained and displayed on the USB recording function activation interface. The request key in the figure indicates the first request key, and prompts user from which website the second activation key can be acquired through the first request key which is defined as the activation key as shown in the figure. Based on the first request key, the TV end can obtain the first activation key through one specific algorithm and store the first activation key for matching with the second activation key.

[0048] S30, acquiring information at a WEB end according to the first request key, matching the first activation key with a second activation key acquired from the WEB end, and activating the USB recording function on condition that the first activation key is consistent with the second activation key.

[0049] The WEB end refers to the internet device including the client end and the server end. The client can be any internet terminal, such as a computer or a smart phone terminal. User can record the first request key when acquiring obtains the first request key from the USB recording function activation interface displayed on the TV end. Then user can log in to the designated WEB site to obtain the corresponding second activation key through the first request key. When user inputs the first request key into the website, the server calculates the corresponding second activation key through the algorithm, and feeds the second activation key back to the client end, and the client end displays the second activation key. Then user inputs the second activation key output by the WEB end to the TV end. The TV matches the first activation key with the second activation key when receiving the second activation key, and activates the USB recording function when the second activation key is consistent with the first activation key.

[0050] The user needs to log in to the designated website when acquiring the second activation key. The designated website is organized by the television manufacturer to provide the user with the process for activating the USB recording function. Since building the commercial server has become a relatively mature technology in the context of the present disclosure and many third parties can provide such services, its implementation is not described in detail here.

[0051] The process of the TV end decrypting code includes acquiring a return value of true through checkActivationKey function, and unlocking the USB recording function according to the return value. In detail, whether the length of second activation key input by the user meets the requirement is judged according to the checkActivationKey function; then whether the S/N serial number of the TV end is empty is judged; taking MashedDecimalLexicon (an out-of-order sequence of from 0 to 9) as input dictionary and MzSNLex as the output dictionary, and converting the Activation key input by user into snFragmentFromResponse through the above-mentioned Convert method; and comparing snFragmentFromResponse with m_slicedSerial obtained from GetResquest before, and unlocking the USB recording function if snFragmentFromResponse is equal to m_slicedSerial.

[0052] Furthermore, in one embodiment, after S30, the method further includes:
paying, by a TV producer, a patent fee according to a quantity of the first activation key, on condition that the USB recording function is successfully activated.

[0053] If the second activation key input by the user matches with the first activation key calculated by the decryption algorithm of the television end, the USB recording function can be unlocked for the user. Meanwhile, the company needs to pay the corresponding patent fee after acquiring that user has decrypted the USB recording function of the machine.

[0054] In the method for customizing the USB recording function according to the embodiment, whether the USB recording function corresponding to the program cache instruction is in an open state is determined, when the program cache instruction is acquired; if not, the first request key is acquired, and the first activation key is also acquired based on the first request key; and the information of the WEB end is obtained according to the first request key, the first activation key is matched with the second activation key obtained from the WEB end, and the USB recording function is activated when the first activation key and the second activation key are consistent with each other. According to the method, the USB recording function is encapsulate. When user needs to use the USB recording function, the specific function can be activated through the activation key obtained from the designated website. The present disclosure provides an innovative idea of customizing the function for user, in detail, when user wants to user some additional functions, the manufacturer pays the extra cost generated, and user only needs to complete a few simple activation operations. As such, the cost can be reduced on the basis of maintaining the integrity of the TV function. User can choice the USB recording function, and the present disclosure also solves the problem: on condition that many users do not use the USB recording function at all, the company has to maintain and pay for the USB recording function for each machine based on this unreasonable market situation.

[0055] Based on the first embodiment, the present disclosure provides a method for customizing a USB recording function according to a second embodiment. Referring to FIG. 3, S20 includes:
S21, on condition that the USB recording function is in an un-open state, acquiring the first request key, and displaying the first request key on the TV end.

[0056] If the user has not successfully activated the USB recording function, it means that the USB recording function is in an unopened state. When the program cache instruction is acquired, the first Request key stored in the memory is obtained and displayed on the USB recording function activation interface of the TV end. As shown in FIG. 4, the request key in the figure represents the first request key, and prompts user from which website the second activation key can be obtained through the first request key which is defined as the activation key as shown in the figure.

[0057] S22, acquiring the first activation key corresponding to the first request key through a preset algorithm.

[0058] Based on the first request key, the TV end can obtain the first activation key through one specific algorithm and store the first activation key for matching with the second activation key.

[0059] In the method for customizing the USB recording function according to the embodiment, the first request key is acquired when the USB recording function is in the closed state, and the first request key is displayed on the TV end; then the first activation key corresponding to the first request key is obtained through the preset algorithm; when user needs to use the USB recording function, one instruction is issued to obtain the first request key displayed on the TV end, and the TV end can also obtain the first activation key based on the first request key, thereby ensuring that the first activation key is obtained according to one specific algorithm. The present disclosure provides a set of complete scheme for encapsulating, encrypting and decrypting the USB recording function, ranging from the definition of Ul, processing of front-end data and back-end data, to the implementation methods in the production process. One of the greatest advantages of the present disclosure is to provide a new scheme for function configuration. In the future, the scheme can be applied on other selectable functions, to realize a user-customized function system, i.e. users can select the functions they need. Therefore, users can select their demanding functions while the cost for the enterprise is also reduced.

[0060] Based on the first embodiment, the present disclosure provides a method for customizing a USB recording function according to a third embodiment. Referring to FIG. 5, S30 includes:
S31, comparing the second activation key with the first activation key to judge whether the second activation key is consistent with the first activation key, on condition that the second activation key of the WEB end is acquired.

[0061] The WEB end refers to the internet device including the client end and the server end. The client can be any internet terminal, such as a computer or a smart phone terminal. User can record the first request key when acquiring obtains the first request key from the USB recording function activation interface displayed on the TV end. Then user can log in to the designated WEB site to obtain the corresponding second activation key through the first request key. The interface for the server end acquiring the activation key is shown in FIG. 6. When user inputs the first request key (that is the request key as shown in the figure) into the website, the server end calculates the corresponding second activation key through the algorithm, then feeds the second activation key back to the client end, and the client end displays second activation key, and then user inputs the second activation key output by the WEB end to the TV end.

[0062] S32, if yes, activating the USB recording function.

[0063] The second activation key is matched with the first activation key when TV receives the second activation key. The USB recording function is activated when the second activation key is consistent with the first activation key.

[0064] Furthermore, in one embodiment, after S31, the method further includes:
if the first activation key is inconsistent with the second activation key, popping up a message to indicate a failure of activation.

[0065] The message for indicating the failure of activation is generated when the first activation key obtained by the TV end through the algorithm is inconsistent with the second activation key obtained by the user through the server end. The message for indicating the failure of activation is displayed on the TV end when the message for indicating the failure of activation is generated, for reminding the user to reactivate the USB recording function.

[0066] In the method for customizing the USB recording function according to the embodiment, whether the second activation key is consistent with the first activation key is determined by comparing the second activation key with the first activation key when the second activation key of the WEB end is acquired; then the USB recording function is activated when the first activation key is consistent with the second activation key. The first activation key obtained by the TV end itself through the algorithm can be used as a tool for checking the second activation key input by the user to judge whether the second activation key is correct, thus ensuring the integrity of the activation function and the reliability of the key.

[0067] Based on the first embodiment, the present disclosure provides a method for customizing a USB recording function according to a fourth embodiment. Referring to FIG. 7, after S30 the method further includes:
S40, storing bar code information scanned by the code scanner on condition that an instruction for storing bar code information is received.

[0068] This embodiment is formed from the perspective of a production line. In order to meet the needs of rapid production in factories and to ensure the uniqueness of the first request key of each machine, the present disclosure stores the first request key in the memory by scanning bar codes during production. That is, the code scanner scans the bar code provided in advance and uniquely corresponding to each machine during production, and then the information identified from the bar code is written into the memory for storage. In this way, not only the uniqueness of the first request key of each machine is satisfied, but also the rapidity requirement during factory production is satisfied.

[0069] S50, converting the bar code information into the first request key.

[0070] The data in the bar code can be stored in the memory after being read by the code scanner, and converted into the first request key.

[0071] Because the unique ID of each machine needs to be burned in the form of bar code during the production process, the present disclosure also provides a method of burning the ID in the form of bar code. The bar code needs to be stored in memory to ensure the uniqueness of each machine and meet the requirements of the algorithm. The bar code identification has 18 digits.

[0072] The TV end converts the bar code information into the first request key. In detail, the S/N serial number data captured from E2 is converted into the first request key, and the parameter aStringToEncrypt is regarded as the data captured from E2, and the data is also regarded as the PID (Product ID) that is burn into E2 through the above-mentioned recorder. That is, each TV has one unique data. The m_slicedSerial is the data needed for decryption. The last five bits of S/N serial number are saved through getRequestKey. The RequestKey to be obtained is stored in aStringToEncrypt pointer. The RequestKey includes challenge key and hash key. Among them, the challenge key is formed by converting aStringToEncrypt, MzSNLex, and AlphaNumLex through the Convert method. In the Convert method, a weight matrix is obtained according to the length of the input character string, and then aStringToEncrypt, MzSNLex, and AlphaNumLex is converted according to the weight matrix; and hash key which is challenge, is obtained processing challenge key and AlphaNumLex through getHash.

[0073] In the method for customizing the USB recording function according to the embodiment, the bar code information scanned by the code scanner is stored when the bar code information storage instruction is received; then the bar code information is converted into the first request key; the bar code is used to store relevant information, and then the relevant information is stored in the television terminal through scanning the bar code on the production line, thereby ensuring the uniqueness of each television and meeting the requirement of the algorithm meanwhile. That is, not only the requirement of fast production is met, but also the accuracy of stored information is ensured.

[0074] The present disclosure provides a method for customizing a USB recording function according to a fifth embodiment. Referring to FIG. 8, FIG. 8 shows a flow chart of a method for customizing a USB recording function according to a fifth embodiment of the present disclosure. The method for customizing the USB recording function includes:
S60, generating and acquiring an acquisition instruction for a second activation key based on the first request key, on condition that the WEB end receives the first request key.

[0075] The embodiment is formed from the perspective of the WEB side. When the user obtains the first request key from the TV end, the user logs in to the assigned website through the client end, and inputs the first request key in the specified location. When the server receives the first request key, the server can calculate the second activation key according to the algorithm, and feed the second activation key back to the client end, and output the second activation key through the client end.

[0076] S70, acquiring the second activation key based on the acquisition instruction for the second activation key.

[0077] The server end may output the second activation key through the algorithm when the acquisition instruction for the second activation key containing the first request key is input into the server end. Specifically, the obtained character strings are reversely matched into an input definition dictionary through getValueFromLex, and a dictionary position matrix is derived; then, AkkuArray and ResultArray matrices are created, AkkuArray is configured for storing the weight matrix at the time of conversion, and ResultArray is configured for storing the converted location matrix; then the nested loop starts to convert, AkkuArray weight matrix modifies the superposition of weight length according to the input length, and ResultArray superposes its original value according to the weight matrix; then the value in the matrix is limited into the range of the output dictionary Index, and if the value exceeds the range, the model is taken according to the length of the output dictionary; finally, the corresponding value is acquired from the Index of ResultArray according to the output dictionary, and the converted string is returned.

[0078] S80, outputting the second activation key through the WEB end, to allow the TV end to activate the USB recording function.

[0079] The WEB end refers to the internet device including the client end and the server end. When the interaction between the client end and the server end is ignored, the client end and the server end are regarded as a whole and combined to form the WEB end. Therefore, when the user inputs the first request key, the WEB end can calculate one second activation key based on the request key, and then output the activation key. The second activation key can be output and displayed on a display, and can also be transmitted to a designated location by other means.

[0080] In the method for customizing the USB recording function according to the embodiment, the second activation key is acquired based on the first request key when the first request key is acquired; then the second activation key is output through the WEB end. Acquiring the second activation key on the website set up by television manufacturer can ensure the accuracy and safety of the key. In addition, the establishment of a commercial server can also conveniently solve the problem of acquiring the second activation key through the first request key.

[0081] Based on the fifth embodiment, the present disclosure provides a method for customizing a USB recording function according to a sixth embodiment. Referring to FIG. 9, S70 includes:
S71, sending the acquisition instruction for the second activation key to the server end, on condition that the client end acquires the acquisition instruction for the second activation key.

[0082] When user obtains the first request key from TV end, the user logs in to the assigned website through the client end, and inputs the first request key in the specified location. Then the first request key is sent to the corresponding server end through the client end. Client end refers to all intelligent terminals that can access the internet, such as computer and smart phone. Since the license fee for the PVR function of the USB recording is paid according to the quantity of keys downloaded by user, the server needs to count the quantity of the activation key, and the manufactures can pay based on this quantity.

[0083] S72: outputting the second activation key, on condition that the second activation key fed back by the server end is acquired based on the second activation key acquiring instruction.

[0084] When receiving the first request key, the server end can obtain the second activation key according to the algorithm, and feed it back to the client end, and then the second activation key is output. The second activation key can be output and displayed on a display, and can also be transmitted to a designated location by other means.

[0085] In the method for customizing the USB recording function according to the embodiment, the acquisition instruction for the second activation key is sent to the server end when the client end acquires the acquisition instruction for the second activation key; the second activation key is output when the second activation key fed back by the server end is obtained based on the second activation key acquiring instruction; and user accesses the designated website through the client end and obtains the second activation key on the website based on the first request key, thereby improving the convenience and ensuring the security of the key.
