In hybrid video coding, an entropy coding scheme transmits the quantized transform coefficients, resulting from block-based transformation and quantization of the difference between the prediction signal and the original signal, and additional side information. The state-of-the-art hybrid video coding standard H. 264/AVC defines two different entropy coding schemes with different complexity-performance trade-off. As a result, the support for two different entropy coding schemes has to be maintained and introduces several problems. To overcome these issues, a unified solution is proposed, which is based on the PIPE/V2V coding concept. It achieves the same complexity-performance trade-offs as the existing entropy coding schemes by scalability. The advantage of the proposed scheme over the existing concept is the usage of the same set of tools for all configurations. Simulation results and complexity analysis.
