Abstract: A latency measurement system includes an event generation device that generates an initial event used to measure system latency. A component test system receives the event and in response outputs a test component output signal and a zero-latency indicator. An electronics system including a multifunction display unit receives the test component output signal and displays a visible element on the multifunction display unit. A camera generates a series of recorded images, where each recorded image contains an image of the zero-latency indicator and an image of the visible element. A processor then determines the system latency by determining a time difference in the series of recorded images between a representation of an occurrence of the event in the image of the zero-latency indicator and a representation of the occurrence of the event in the image of the visible element.

Abstract: A preamble identifier flag in a reserved portion of a data field synchronization segment in a digital television (DTV) data field identifies the presence of preamble training data in a forward error correction (FEC) encoded portion of the DTV data field. The data field synchronization segment is not FEC encoded, thereby allowing detection of the preamble identifier flag without FEC decoding. The detection at a receiver of the preamble identifier flag in a DTV data field allows receiver elements, such as an equalizer and a FEC decoder, to more readily obtain and utilize the preamble training data, thereby enhancing reception and/or simplifying receiver design.
