To achieve high visual quality of intra-frame coding in order to minimize the visual quality degradation caused by color loss, the authors previously presented an RGB-domain inter-color compensation algorithm using strong correlation between RGB color components. Based on that inter-color compensation algorithm, this paper presents a 1080p 60Hz CODEC system architecture designed to process a bit-rate of up to approximately 100Mbps in real time. Both the encoding and decoding processes are pipelined on a macroblock level. Since syntax processing is a bottleneck to supporting speeds of up to 100Mbps, a high performance context-adaptive variable length coding architecture exploiting the look-ahead technique is included in the proposed design. The final chip implementation can achieve real-time encoding and decoding of 1080p 60Hz videos with reasonable hardware cost and operating clock frequency. |
