Abstract
A video frame loss recovery scheme essentially belongs to a loss packet in a low overhead and low complicated recovery scheme and serves to protect P-frames of a group of pictures (GOP). Namely, if a P-frame of the same group of pictures loses during the transmission, a compensation frame could be applied to serve and recovered as a lost P-frame, thereby promoting to a preferable video presenting performance of a receiver.
Claims9
A video frame loss recovery scheme comprising at least one transmitter and at least one receiver;
- wherein, said transmitter transmitting at least one group of pictures through an image encoder, and said group of pictures comprising at least one P-frame;
- said image encoder further coupling to an XOR summation device, and said P-frame transmitting into said XOR summation device to generate a compensation frame;
- said group of pictures and said compensation frame being transmitted to said receiver together, whereby while any one of said P-frame in said same group of pictures loses during a transmission, said compensation frame could be directly served as a lost P-frame, or said compensation frame and a non-lost P-frame could be calculated through an XOR decoding device, from which said lost P-frame could be recovered for promoting an video performance of said receiver.
