摘要
Described herein is a novel transcoding technique called lossless inter frame transcoding (LIFT) for improving the error resilience of video streaming. According to various embodiments, conventional coded blocks are selectively transcoded into new transcoded blocks. At the decoder, the transcoded blocks can be transcoded back to the conventional coded blocks when prediction is available and can also be robustly decoded independently when prediction is unavailable. According to another embodiment, an offline transcoding and online composing technique is provided for generating a composite frame using the transcoded and conventional coded blocks and adjusting the ratio of the transcoded blocks, thereby achieving error robustness scalability.
