| 发明名称 | Overconing lost IP packets in streaming video in IP networks | ||
| 摘要 | 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. | ||

| 主权项 | 1. A computer-implemented method performed by a computerized device, comprising: receiving by a computing device 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; sending to an encoder information indicating that a first packet is missing; receiving from the encoder at least one first frame in which at least one first part is encoded independently of any preceding frame and at least another part is encoded based on a preceding frame; decoding the at least one first frame; prior to receiving from the encoder at least one second frame in which at least one second part is encoded independently of a preceding frame and at least a further part is encoded based on a preceding frame: sending to the encoder additional information indicating that a second packet is missing in the first frame;receiving from the encoder at least one third frame in which the at least one first part is encoded independently of another frame, and at least one other part is encoded based on a preceding frame; anddecoding the at least one third frame; receiving from the encoder the at least one second frame; and decoding the at least one second frame. | ||
