摘要:
Techniques are provided herein to produce encoded video bitstreams and to similarly decode encoded video bitstreams according to a coding standard not supported by an on-chip encoder/decoder. For purposes of encoding, a video sequence is received at a first device. A first bitstream is generated at the first device by encoding the video sequence according to a first coding standard and information associated with the video sequence is generated at the first device according to a second coding standard. The first bitstream and the information are then transmitted to a second device. At the second device the first bitstream is decoded to produce a second bitstream. The second bitstream and the information are combined by removing syntax elements associated with the first coding standard from the second bitstream and adding the information to produce a third bitstream according to the second coding standard. Similar techniques are provided for decoding an encoded bitstream to recover a video sequence.
