New Video Coding Technologies and its Effects on Next Generation Plant Infrastructures

This paper examines some of the plant changes happening today required by the introduction of new high density video transcoder solutions for broadcast service providers in the cable/satellite/telco industries. It will cover signal workflows, distribution, density, and monitoring. Video & audio codecs are briefly touched upon, but the majority of this paper deals with how new video technologies and how increased density can affect plant, network, signal, and device infrastructures. The paper will investigate the impacts from increased signal density due to adaptive streaming, and processor density resulting from improvements in CPUs, GPUs, ASICs, and DSPs as well as the changes to device rack footprint. From the distribution perspective, the paper will describe how multicast, non-baseband distribution is becoming more commonplace, which allows for addressing multiple devices at the same time. In terms of routers, it will examine management of traffic flows onto subnets with multiple source devices. Lastly, this paper will examine the effects of monitoring in this new environment without being too prohibitive.
