| Popis: | The state-of-the-art hybrid video coding standard H.264/AVC defines two entropy-coding schemes with different complexity-performance trade-offs. Supporting these two schemes within a single standard raises several problems ranging from higher efforts for product development to increased silicon costs for hardware implementations. To overcome these issues, this work proposes a unified and complexity-scalable entropy-coding framework that is based on PIPE/V2V. The proposed framework uses a single set of tools for all configurations and achieves the same complexity-performance trade-offs as the existing entropy-coding schemes through scalability. |
