The wireless terminal may be a mobile terminal, like a mobile phone (or referred to as a "cellular" phone) or a computer with a mobile terminal, for example, a portable, pocket, handheld, built-in-computer, or vehicle-mounted mobile apparatus, which exchanges audio and/or data with the radio access network, for example, a personal communication service (PCS, Personal Communication Service) phone, a cordless phone, a session initiation protocol (SIP) phone set, a wireless local loop (WLL, Wireless Local Loop) station, or a personal digital assistant (PDA, Personal Digital Assistant). The wireless terminal may also be referred to as a system, a subscriber unit (Subscriber Unit), a subscriber station (Subscriber Station), a mobile station (Mobile Station), a mobile (Mobile), a remote station (Remote Station), an access point (Access Point), a remote terminal (Remote Terminal), an access terminal (Access Terminal), a user terminal (User Terminal), a user agent (User Agent), a user apparatus (User Apparatus), or a piece of user equipment (User Equipment).

    [0017] An embodiment of the present invention provides a method for program information exchange. As shown in FIG. 1, the method includes:
    S101: A apparatus for program information exchange obtains a program comment instruction.

    [0018] Exemplarily, a manner for the apparatus for program information exchange to obtain the program comment instruction may be that, the apparatus for program information exchange receives a program comment instruction which is input by a user by using a control apparatus such as a remote control.

    [0019] When the user is watching a television program, if the user wants to make a comment on a current program or wants to know what comments are made by others on the current program, the user can input the program comment instruction by using the control apparatus such as a remote control. For example, a program comment button may be set on the remote control, and the user can send the program comment instruction only by pressing the program comment button, so as to trigger the apparatus for program information exchange to extract information about the current program from a pre-established database.

    [0020] S102: The apparatus for program information exchange extracts information about the current program from a pre-established database according to the program comment instruction.

    [0021] It is necessary to explain the pre-established database herein. The pre-established database may be stored on a server end, for example, a broadcast television network terminal. The server packages together program audio and video streams and program-related information, such as a program name, an episode, a comment address, and a server address, and broadcasts the package in a wired or wireless manner. The packaging mentioned in the embodiment of the present invention refers to performing data grouping for a compressed file to meet a requirement of signal transmission.

    [0022] Then, after obtaining the program comment instruction, the apparatus for program information exchange extracts the information about the current program from the pre-established database, where the information may include the program name, episode, comment address, server address, and the like.

    [0023] S103: If the information includes a program comment address, the apparatus for program information exchange sends the program comment address to a piece of user equipment, so that a user acquires a comment on the current program or makes a comment on the current program according to the program comment address.

    [0024] After extracting the information about the current program, the apparatus for program information exchange determines whether the information includes the program comment address. If the information includes the program comment address, the apparatus for program information exchange sends the program comment address to the user equipment, for example, sends the program comment address to the user equipment via a wireless router. After receiving the program comment address from the apparatus for program information exchange, the user equipment can connect to a related webpage according to the program comment address. Then, the user using the user equipment may acquire a comment on the current program or make a comment on the current program by using the user equipment.

    [0025] It should be supplemented that the apparatus for program information exchange does not send the program comment address to all user equipment. The apparatus for program information exchange performs permission verification for the user equipment, and then communicates only with the user equipment that passes permission authentication. For example, the apparatus for program information exchange may perform permission verification once for apparatus and establish a connection with the user equipment when the apparatus is switched on, and then send the program comment address to the user equipment.

    [0026] S104: If the information does not include a program comment address, the apparatus for program information exchange sends a server address in the information to a piece of user equipment, so that the user equipment establishes a connection with a server according to the server address, thereby enabling the user to make a comment on the current program by using the user equipment.

    [0027] After extracting the information about the current program, the apparatus for program information exchange determines whether the information includes the program comment address. If the information does not include the program comment address, the apparatus for program information exchange sends the server address in the information to the user equipment. Similarly, the server address can be sent to the user equipment via the wireless router. After receiving the server address from the apparatus for program information exchange, the user equipment may connect to the server according to the server address, and the server may create a comment community for the program. Then, the user using the user equipment can make a comment on the current program by using the user equipment. Further, the server stores a newly established program comment address in the information about the program, and stores the information in the pre-established database.

    [0028] It should be noted that in the embodiment of the present invention, step S103 and step S104 may be executed in any sequence. Step S103 describes a case where the information includes a program comment address, and step S104 describes a case where the information does not include a program comment address; therefore, there is no limitation for time sequence.

    [0029] In the method for program information exchange provided by the embodiment of the present invention, after a program comment instruction is obtained, information about a current program is extracted from a pre-established database according to the program comment instruction; if the information includes a program comment address, the program comment address is sent to a piece of user equipment, so that a user acquires a comment on the current program or makes a comment on the current program according to the program comment address; or if the information does not include a program comment address, a server address in the information is sent to a piece of user equipment, so that the user equipment establishes a connection with a server according to the server address, thereby enabling the user to make a comment on the current program by using the user equipment. With the solution, the user can make a comment by using the user equipment on the program currently being watched without adding an external input device.

    [0030] An embodiment of the present invention provides a method for program information exchange. As shown in FIG. 2, the method includes:
    S201: A apparatus for program information exchange performs permission authentication for a piece of user equipment, and communicates only with the user equipment that passes permission authentication.

    [0031] Exemplarily, the apparatus for program information exchange may perform permission verification for and establish a connection with the user equipment when the apparatus is switched on, and then communicate only with the user equipment that passes permission authentication.

    [0032] It should be noted that in the embodiment of the present invention, it is merely a preferred solution that the apparatus for program information exchange performing permission authentication for the user equipment is set to be the first step of the method for program information exchange. That is, it is a preferred solution that, the apparatus for program information exchange performs permission verification only once for and establishes a connection with the user equipment when switched on. However, the specific implementation manner is not limited thereto. The apparatus for information exchange may also perform permission verification when the apparatus for information exchange needs to send information to the user equipment, which is not limited by the embodiment of the present invention.

    [0033] S202: The apparatus for program information exchange obtains a program instruction, where the program instruction is used to indicate a program that a user needs to watch.

    [0034] Exemplarily, a manner for the apparatus for program information exchange to obtain the program instruction may be that, the apparatus for program information exchange receives a program instruction which is input by the user by using a control apparatus such as a remote control, where the program instruction is used to indicate which program the user wants to watch.

    [0035] S203: The apparatus for program information exchange extracts corresponding program audio and video streams from a pre-established database according to the program instruction.

    [0036] After obtaining the program instruction, the apparatus for program information exchange extracts corresponding program audio and video streams from the pre-established database. It is pointed out in the previous embodiment that, a server packages together program audio and video streams and program-related information, such as a program name, an episode, a comment address, and a server address, and broadcasts the package in a wired or wireless manner. Then, the apparatus for program information exchange may extract corresponding program audio and video streams.

    [0037] S204: The apparatus for program information exchange performs descrambling and decoding for the audio and video streams.

    [0038] The server may perform scrambling and encoding for a packaged file when packaging the program audio and video streams and the program-related information. That is, the pre-established database stores program streams formed after the server scrambles and encodes the program information and the program audio and video streams. For example, some programs that need to be paid can be watched only after being descrambled and decoded. Therefore, the apparatus for program information exchange performs descrambling and decoding for the extracted audio and video streams.

    [0039] S205: The apparatus for program information exchange outputs descrambled and decoded audio and video streams.

    [0040] After performing descrambling and decoding for the audio and video streams, the apparatus for program information exchange outputs the descrambled and decoded audio and video streams, and specifically, may output to a display apparatus, for example, a television set, so that the user can watch the program through the display apparatus.

    [0041] S206: The apparatus for program information exchange obtains a program comment instruction.

    [0042] When the user is watching a television program, if the user wants to make a comment on a current program or wants to know what comments are made by others on the current program, the user can input the program comment instruction by using the control apparatus such as a remote control. For example, a program comment button may be set on the remote control, and the user can send the program comment instruction only by pressingpressing the program comment button, so as to trigger the apparatus for program information exchange to extract information about the current program from the pre-established database.

    [0043] S207: The apparatus for program information exchange extracts the information about the current program from the pre-established database according to the program comment instruction.

    [0044] After obtaining the program comment instruction, the apparatus for program information exchange extracts the information about the current program from the pre-established database, where the information may include the program name, episode, comment address, server address, and the like.

    [0045] S208: If the information includes a program comment address, the apparatus for program information exchange sends the program comment address to the user equipment, so that the user acquires a comment on the current program or makes a comment on the current program according to the program comment address.

    [0046] After extracting the information about the current program, the apparatus for program information exchange determines whether the information includes the program comment address. If the information includes the program comment address, the apparatus for program information exchange sends the program comment address to the user equipment, for example, sends the program comment address to the user equipment via a wireless router. After receiving the program comment address from the apparatus for program information exchange, the user equipment can connect to a related webpage according to the program comment address. Then, the user using the user equipment may acquire a comment on the current program or make a comment on the current program by using the user equipment.

    [0047] S209: If the information does not include a program comment address, the apparatus for program information exchange sends a server address in the information to the user equipment, so that the user equipment establishes a connection with a server according to the server address, thereby enabling the user to make a comment on the current program by using the user equipment.

    [0048] After extracting the information about the current program, the apparatus for program information exchange determines whether the information includes the program comment address. If the information does not include the program comment address, the apparatus for program information exchange sends the server address in the information to the user equipment. Similarly, the server address can be sent to the user equipment via the wireless router. After receiving the server address from the apparatus for program information exchange, the user equipment may connect to the server according to the server address, and the server may create a comment community for the program. Then, the user using the user equipment can make a comment on the current program by using the user equipment. Further, the server stores a newly established program comment address in the information about the program, and stores the information in the pre-established database.

    [0049] Similarly, in the embodiment of the present invention, step S208 and step S209 may be executed in any sequence. Step S208 describes a case where the information includes a program comment address, and step S209 describes a case where the information does not include a program comment address. Therefore, there is no limitation for time sequence.

    [0050] In the method for program information exchange provided by the embodiment of the present invention, after a program comment instruction is obtained, information about a current program is extracted from a pre-established database according to the program comment instruction; if the information includes a program comment address, the program comment address is sent to a piece of user equipment, so that a user acquires a comment on the current program or makes a comment on the current program according to the program comment address; or if the information does not include a program comment address, a server address in the information is sent to a piece of user equipment, so that the user equipment establishes a connection with a server according to the server address, thereby enabling the user to make a comment on the current program by using the user equipment. Through the solution, the user can make a comment by using the user equipment on the program currently being watched without adding an external input device.
