An H.264/AVC scalable extension and high profile HDTV 1080p encoder chip

The first single-chip H.264/AVC HDTV 1080 p encoder for scalable extension (SVC) with high profile is implemented on a 16.76 mm² die with 90 nm process. It dissipates 349/439 mW at 120/166 MHz for high profile and SVC encoding. The proposed frame-parallel architecture halves external memory bandwidth and operating frequency. Moreover, the prediction architecture with inter-layer prediction tools are applied to further save 70% external memory bandwidth and 50% internal memory access.
