Patent ID: 8774273

Claim:
A method for decoding an I-frame only encoded bitstream of digital video content, the method comprising: decoding an encoded bitstream, wherein decoding the encoded bitstream generates decoded syntax elements and decoded pixel information; creating an access point for each slice of the encoded bitstream currently being decoded to enable re-use of the slice in different pictures by saving state information related to the decoding, saving the decoded syntax elements, and saving the decoded pixel information, wherein the saved state information comprises a bit position in the bitstream, the state of context-adaptive binary arithmetic coding, context information, and bin information; storing the access point and the encoded bitstream in a memory; synchronizing a subsequent decoding operation to the desired access point in the encoded bitstream by first retrieving the saved state information, the saved decoded syntax elements, and the saved decoded pixel information, then setting the state of an entropy decoder using the retrieved state information to restore its internal state when the related slice of the encoded bitstream was originally decoded.
