资料介绍
As broadband connectivity adoption rate continues to increase and the capacity of the underlying network continues its rapid growth, moving and processing media content is taking center stage in various segments of both the enterprise and the consumer markets. The unstoppable move towards convergence of data, voice and video processing onto an IP-based network has had significant implication on the digital signal processing performance requirements at various nodes of this network. With applications ranging from live broadcast of high definition television programming to real-time transcoding and translating of video between Wireline and wireless networks, video processing requirements have continued to increase in complexity and performance. When one considers the sheer volume of pixels that need to be captured, pre-processed, compressed, packetized, possibly encrypted, and transmitted in any real-time broadcast type application of high definition video, particularly given the complexity of some of the latest advanced video coding schemes (H.264 and WMV9), one can easily appreciate the raw processing horsepower needed to accomplish such tasks.……
