Abstract: With the establishment of the MPEG-2 video compression standard and widespread deployment of digital terrestrial networks, the door is open to manufacturers to develop portable digital video links using the best aspects of both these technologies. The objective is to produce reliable video feeds for a wide range of mobile applications; until now, these video links have been mainly satisfied by analog technology. The move to digital has been demonstrated successfully, but often incurs the drawbacks of large end-to-end delays, high bandwidth, or bulky equipment overhead. This paper discusses how digital video links for mobile applications can be achieved by combining MPEG-2 video compression, terrestrial modulation, RF up-conversion, and low-power radio amps in a small, DC-powered unit. It will describe the technology and algorithms used, comparing them with other approaches, and the experience gained from deploying equipment in the field.

bio
Ian Trow received his first degree from the University of Sussex in 1989. After graduation, he worked for Sony Broadcast as an R&D engineer designing high-definition video equipment. In 1993, he joined Snell & Wilcox working on video compression and digital multistandard composite decoding. Since 1996, Trow has worked at TANDBERG Television (formally NDS) and is responsible for the development of mobile contribution products, primarily targeted at the professional broadcast market, but being developed increasingly for non-broadcast applications. These products allow the delivery of MPEG-2 compressed material over satellite (DSNG) and terrestrial (DENG) links.
