Abstract
Techniques for optimizing the Context-based Adaptive Binary Arithmetic Coding (CABAC) bitstream decoding are disclosed. In one configuration, a device has a first processing circuit operative to decode a Context-based Adaptive Binary Arithmetic Coding (CABAC) bitstream into an intermediate signal having a CABAC decoded standard format and a decoded order. A second processing circuit decodes the intermediate signal using a non-CABAC decoding standard. A buffer is provided between the first and second processing circuits to improve processing speeds.
