摘要
A codec configured to operate in a sequential mode extends the current AVC standard in order to provide support for coding high resolution still image pictures within the AVC coding of a lower resolution video. The sequential mode codec is configured according to the modified AVC standard. The codec is capable of capturing an AVC video stream while concurrently capturing high resolution still images at random intervals relative to the video stream. Each captured high resolution still image is embedded within the video stream. The video stream including the embedded high resolution still images is encoded as a single layer bit stream. Each embedded high resolution still image signals or forces the start of a new GOP in the coded video sequence. The AVC standard is extended to include new syntax for the sequence parameter sets. In one embodiment, a modified sequence parameter set defines a new profile that signals the presence of a high resolution still image in sequence with AVC video.
