H.264/AVC Codec System for IP Networks

The start of digital terrestrial broadcasting and the popularization of widescreen TV have initiated a recent shift in video content to the high-definition (HD) format. Meanwhile, thanks to high-speed, low-cost networks, video distribution services via IP networks have become more familiar. Also, the recent needs for collecting and delivering HD video contents with a large data volume via low-cost IP networks have become more conspicuous. To address these demands, Fujitsu has developed a video codec called IP-9500 based on the latest video coding technology H.264/AVC that enables more than twice the data compression ratio compared with conventional coding technology. This product is the world's first example of commercializing real-time transmission of HD video contents via IP networks. This paper describes the IP-9500, which leads to the realization of versatile visual solutions domestically and internationally.
