Abstract (en)
[origin: GB2469281A] A method (200) for asynchronous live video transmission over a communication network which comprises the receipt of individual requests from a video client for the transmission of a single frame which has not previously been transmitted. Requests specify the encoding parameters (I-frame periodicity, quantisation and resolution) determined by the video client. Frames of live video are captured (204) and encoded (206) according to the parameters specified in the request. The parameters may be changed in response to available bandwidth. Retransmission of lost or corrupted frames may be requested with changed parameters. A rolling buffer may be used to store frames after encoding.
