![]() ![]() Probably the greatest advantage lies in its ability to transport the entire triple-play package-voice, video, and data-over the same infrastructure, which lowers the cost and complexity of the transport network. The use of Ethernet as a transport protocol for video provides several advantages. This article will review the advantages of Gigabit Ethernet as a transport protocol, new testing challenges posed by the MPEG-2 transport stream, and how the challenges are met by new Gigabit Ethernet test sets. As with any troubleshooting technique, it is critical to find the root cause of the problem. Many problems within the MPEG layer are the result of lower-level factors, such as latency, jitter, throughput, or utilization. ![]() In this context, MPEG analyzers or Ethernet test sets alone can no longer provide adequate testing and troubleshooting. In particular, the proper provision of IP television (IPTV) and video-on-demand (VoD) requires simultaneous testing of both the transport system and the multicast video signals, such as MPEG-2. ![]() Deploying video services over Gigabit Ethernet presents service providers with a new set of testing challenges. ![]()
