HDTV standards and procedures for digital broadcasting
This eduGuide is designed for professional video, which begins with the design, specification, operating or maintaining the digital video broadcasting and distribution systems for HDTV. More than 50 years our industry uses television technology primarily analog in nature. True, some of the digital technology has been used in equipment for the broadcast to standard definitions or formats NTSC and PAL systems, but its use was limited and eventually converted back to an analog signal for distribution and broadcasting.
HDTV is now the first to broadcast technology, which is to be exclusively digital image capture from a TV show to the consumer. Many different technologies are used where video and audio, is undergoing many transformations from beginning to end. This will help you understand chain eduGuide technologies used, the standards for them, copper and the distribution of optical fiber, and video professionals practice developed for the new world HDTV.
The Role of technical standards
The broadcasting sector, in contrast to the A/V and computer industry historically has been a proponent of and practices of technical standards for video and audio processing and distribution. The reason is simple: interoperability. Broadcaster and in the related sectors of professional video, must be able to select the best equipment for the job. Whereas, all the equipment in the distribution or edit suite will have to process the same video and audio, it is necessary to define and comply with the standards of the interfaces between the different pieces of equipment.
There are several technical standards organization in the world, which develops and supports these standards, but perhaps the most well known is the SMPTE. Society of Motion Picture and Television Engineers (SMPTE) has a membership and participation from individuals, broadcasters and producers from around the world. The expertise and experience to bear in this group creates a forum for the development of a very strong and durable standards.
Buyer and user of the equipment for the broadcast is the final recipient of this process. You can be sure that products that are compatible with a particular set of standards allows video and audio signals between them recognizable manner, without the need for additional processing or link. The benefit to the user is the lower design and operational costs and a wider choice of equipment for specific application without locked one device manufacturer, the use of proprietary interfaces and protocols.
