A method and apparatus for video encoding to generate a partitioned bitstream without buffering transform coefficient and/or prediction data for subsequent coding units are disclosed. An encoder incorporating an embodiment according to the present invention receives first video parameters associated with a current coding unit, wherein no first video parameters associated with subsequent coding units are buffered. The encoder then encodes the first video parameters to generate a current first compressed data corresponding to the current coding unit. A first memory address in the first logic unit is determined and the encoder provides the current first compressed data at the first memory address in the first logic unit.

Method and apparatus of video encoding with partitioned bitstream

A method and apparatus for loop processing of reconstructed video in an encoder system are disclosed. The loop processing comprises an in-loop filter and one or more adaptive filters. The filter parameters for the adaptive filter are derived from the pre-in-loop video data so that the adaptive filter processing can be applied to the in-loop processed video data without the need of waiting for completion of the in-loop filter processing for a picture or an image unit. In another embodiment, two adaptive filters derive their respective adaptive filter parameters based on the same pre-in-loop video data. In yet another embodiment, a moving window is used for image-unit-based coding system incorporating in-loop filter and one or more adaptive filters. The in-loop filter and the adaptive filter are applied to a moving window of pre-in-loop video data comprising one or more sub-regions from corresponding one or more image units.

Method and apparatus for loop filtering

A method of binarizing an input symbol using a hybrid Truncated Rice/k-th order exp-Golomb binarization scheme with a Rice Parameter includes: determining a threshold; comparing the input symbol with the threshold; constructing a codeword using a Truncated Rice (TR) binarization process for the input symbol when a comparison result belongs to a first type of comparison result; and constructing a codeword with an initial prefix and a suffix for the input symbol when the comparison result belongs to a second type of comparison result; wherein the suffix is constructed using an exp-Golomb binarization process.

Method and system for symbol binarization and de-binarization

A method for generating a decoded value from a codeword which is binarized utilizing a concatenated unary/k-th order Exp-Golomb code includes: identifying a first portion of the codeword, a second portion of the codeword and a third portion of the codeword; generating an offset according to the second portion; decoding the third portion to generate an index value; and generating the decoded value by adding the offset and the index value.
