Abstract
A technique for decoding an encoded bitstream of digital video content involves decoding a bitstream, wherein decoding the bitstream generates decoded syntax elements and decoded pixel information, creating an access point in the currently decoded bitstream by saving state information related to the decoding, saving the decoded syntax elements, and saving the decoded pixel information, and synchronizing a subsequent decoding operation to the access point utilizing the saved state information, the saved decoded syntax elements, and the saved decoded pixel information.
Claims20
A method for decoding an encoded bitstream of digital video content, the method comprising:
- decoding a bitstream, wherein decoding the bitstream generates decoded syntax elements and decoded pixel information;
- creating an access point in the currently decoded bitstream by saving state information related to the decoding, saving the decoded syntax elements, and saving the decoded pixel information;
- and
- synchronizing a subsequent decoding operation to the access point utilizing the saved state information, the saved decoded syntax elements, and the saved decoded pixel information.
A decoder for decoding an encoded bitstream of digital video content, the decoder comprising:
- an entropy decoder configured to decode an encoded bitstream, whereby the process of decoding the encoded bitstream causes changes in state within the entropy decoder;
- and
- an arbitrary access engine connected to the entropy decoder for creating access points in the encoded bitstream that is decoded by the entropy decoder, wherein the access points allow arbitrary access to the encoded bitstream for subsequent decoding by the entropy decoder.
