Overconing lost IP packets in streaming video in IP networks
Abstract:
A computer-implemented method, apparatus and computer program product for recovering from lost packets in video transmissions, the method performed by a computerized device, comprising: receiving by a computing device associated with a subscriber a frame constituting a part of video transmission, from an encoder; decoding the frame; determining that a packet within the frame is missing or corrupted; notifying an encoder about a missing packet; receiving from the encoder a first frame in which a first part is encoded independently of a preceding frame; decoding the first frame; receiving from the encoder a second frame in which a second part different from the first part is encoded independently of a preceding frame; and decoding the second frame.
