Abstract
An apparatus comprising an encoder circuit and a storage circuit. The encoder circuit may be configured to generate a reliability score and a referral score for each partition in an input data stream. The input data stream may be encoded based upon the reliability score and the referral score for each partition. The storage circuit may be configured to store the reliability score for each partition of the input data stream.
Claims20
An apparatus comprising:
- an encoder circuit configured to generate a reliability score and a referral score for each partition in an input data stream, wherein the input data stream is encoded based upon the reliability score and the referral score for each of said partitions;
- and
- a storage circuit configured to store the reliability score for each of said partitions of said input data stream, wherein said encoder circuit is further configured to refine said reliability score and said referral score for each of said partitions over a number of iterations.
An apparatus comprising:
- means for generating a reliability score and a referral score for each partition of an input data stream, wherein the input data stream is encoded based upon the reliability score and the referral score for each partition;
- and
- means for storing the reliability score for each partition of said input data stream, wherein said means for generating said reliability score is further configured to refine said reliability score and said referral score for each of said partitions over a number of iterations.
A method for accounting for prediction dependencies in an encoding process comprising the steps of:
- (A) generating a reliability score and a referral score for each partition of an input data stream using a circuit;
- (B) storing the reliability score for each of said partitions of said input data stream in a memory;
- and
- (C) encoding said input data stream based upon the reliability score and the referral score for each of said partitions, wherein said encoding includes refining said reliability score and said referral score in a current iteration based on temporal and spatial prediction dependencies established from a previous iteration.
