Abstract: In some aspects, the disclosure is directed to methods and systems for a context-adaptive binary arithmetic encoder and decoder utilizing a fixed point design for range and context updates. Symbol probabilities and probability adaptation factors can be scaled to a predetermined range, such as an 8-bit range, reducing the need for complex and operationally costly table look-ups.

Abstract: A system may receive an input stream for a coding operation by a coding device. The system may determine a processing device to assist the coding device with the coding operation. The processing device may generate an indicator containing coding information or other coding assistance by processing the input stream. The processing device may send the indicator to the coding device. In some cases, the indicator may be embedded in the metadata of the stream by the processing device. The indicator may be extracted by the coding device. After reception of the indicator, the coding device may execute the coding task while using the information in the indicator to assist.

Abstract: A video encoding system uses overlapped tiles. The system reduces or eliminates cross-core data communication when tiles are processed in parallel on multi-core platforms. The overlapped tiles are designed to simplify the multi-core codec design by avoiding cross core data communication while still maintaining good video quality along tile boundaries.
