The document discusses technologies for improving jitter for broadcaster content delivery over broadband networks. It summarizes that IEEE 1588 Grandmaster and Slave Clock and RTP are still solutions for multicast video transport. It also discusses Precision Timing Protocol versus Synchronized Ethernet and developments in their adoption. Recent test results showed that HD video in MPEG-4 at 8-10 Mbps performs similarly to MPEG-2, and at 18 Mbps is comparable to SD in MPEG-2. Future work on incorporating carrier grade synchronization into IP is suspended.
