The IEEE 1588 Precision Timing Protocol defines a set of techniques for synchronizing various devices across packet-based networks, including Ethernet switches and IP routers.

Audio Video Bridging technology is being considered for use in high-performance Ethernet networks as a potential replacement for SDI video infrastructure in the studio.

Many useful types of signals are synchronous, meaning that they use bit patterns that are transmitted using a built-in, fixed-frequency clock signal.

Over-the-air DTV transmitters are relatively easy to test, at least with respect to the integrity of the outgoing video stream.

Mobile video is poised to enter a period of rapid growth, as new equipment becomes available and service offerings proliferate.

As previously covered in this column, IEEE 1588 Precision Time Protocol (PTP) is an essential part of a modern all-IP media production system.

In many broadcast television applications today, forward error correction allows recovery from errors that occur during transmission.
