Home Networking Gets Ready To Go Mainstream. Home networking ingredient providers and system OEMs are coming to the realization that data communications is but one facet of in-home networks. It has become apparent that voice and video content will also be widely distributed within the home. Unlike data transmission, voice and video depend more on reduced latency, accurate delivery and prioritization. Parameters for delivery of service need to be defined and implemented.
Low latency is important because voice and video are intrinsically time-sensitive.
By contrast, most data streams are asynchronous and are not high priority. Accurate delivery of voice and video signals is key because retransmission of lost packets of such signals is of no value. Therefore, the initial transmission needs to be robust and accurate. The complexity factor greatly increases with video content that typically has an accompanying audio track. The two streams need to be time-stamped to achieve synchronization.
