TECHNIQUES FOR RATE-DISTORTION OPTIMIZATION IN VIDEO COMPRESSION |
| 摘要 |
Various embodiments are generally directed to techniques for reducing processing and/or storage resource requirements for RDO in compressing motion video. A device to compress motion video includes a first cost calculator to derive a first bitcost value of using a quantized coefficient of a quantized coefficient block of a frame of a video in compressing the video, the first bitcost value based on a context model of a context-adaptive binary arithmetic coder (CABAC); and a second cost calculator to derive a second bitcost value of replacing the quantized coefficient with an alternate value derived from the quantized coefficient in compressing the video, the second bitcost value based on the context model. Other embodiments are described and claimed. |

1. A device to compress motion video comprising:
a first cost calculator to derive a first bitcost value of using a quantized coefficient of a quantized coefficient block of a frame of a video in compressing the video, the first bitcost value based on a context model of a context-adaptive binary arithmetic coder (CABAC); and a second cost calculator to derive a second bitcost value of replacing the quantized coefficient with an alternate value derived from the quantized coefficient in compressing the video, the second bitcost value based on the context model. |
