Advances in Videophone Technology Change the Face of World Broadcasting; Reporters in Middle East Rely on Talking Head Videophone for Quick Feeds from Remote Locations.Business/Technology Editors WILMINGTON, N.C.--(BUSINESS WIRE)--Oct. 11, 2001 Satellite videophones are changing the face of international television reporting as broadcasting organizations around the world bid to break the news of current world events faster than ever. At the heart of the race is the Talking Head VideoReporter, a new ruggedized videophone (1) (VideoPhone) A line of videophones (definition #1 below) from AT&T that were introduced in the early 1990s and later pulled off the market due to poor sales. The first models came with a price tag above $1,000, and a pair were needed.

See video codec and data compression. video compression - Compression of sequences of images. expertise of Motion Media Technology (www.motion-media.com). Together the two have developed a new vehicle for transmitting vital first pictures of breaking news from remote locations. The Talking Head videophone is currently being used by CNN CNN or Cable News Network Subsidiary company of Turner Broadcasting Systems. It was created by Ted Turner in 1980 to present 24-hour live news broadcasts, using satellites to transmit reports from news bureaus around the world. , AOL (A division of Time Warner, Inc., New York, NY, www.aol.com) The world's largest online information service with access to the Internet, e-mail, chat rooms and a variety of databases and services. Time Warner's international news channel, to file exclusive reports from around the word, including Afghanistan and Pakistan. CNN now has satellite videophones in most of its 30 overseas bureaus.

It is cost-effective technology that really enhances our operations in the more inaccessible areas in the field that we report from." Jordan continued, "We have used the videophone to provide immediate live pictures from places as diverse as the tip of Norway when we reported on the Kursk submarine tragedy and Hainan Island in China to cover the release of the US flight crew by the Chinese government. Most recently, Nic Robertson's videophone reports out of Kabul formed the last Western television reports out of the region before all foreign journalists were asked to leave." Talking Head vs Beeper beeper - pager The Talking Head videophone replaces the reporter's still photograph and audio telephone report, known as the beeper, with live, high impact video reports. Housed in a waterproof box, smaller than a briefcase, the Talking Head is capable of sending uncut reports from correspondents via ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. and satellite technology. Images from a video camera are fed via the videophone, digitally compressed, and sent to a small satellite terminal that beams the data via satellite or ISDN to the studio. The data is transmitted at 64 or 128 kbps--up to four times as fast as a standard telephone modem. The "Art of Picture Quality" Stuart Ross, Chief Technical Officer at Motion Media Technology, stated, "Successfully applying videoconferencing to the news business meant facing several challenges. To produce a high quality picture, a delicate balance had to be struck between picture resolution, smooth motion, and object detail. The Talking Head videophone accomplishes this by using a multiprocessor DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive (digital signal processing See DSP. Digital Signal Processing - (DSP) Computer manipulation of analog signals (commonly sound or image) which have been converted to digital form (sampled). ) architecture that separates video, audio, and communications functions. This design, combined with our suite of sophisticated video compression algorithms, allows for maximum video performance." Ross continued, "The `art of picture quality' is a delicate science that combines advanced video compression and decompression techniques with noise filtering and bandwidth considerations. Even over lower bandwidth communication channels, such as satellite data links and analog phone lines, we have been able to achieve respectable results, as evidenced by the reports coming out of Afghanistan." "No Longer a Target Because of Satellite Dish" The Talking Head videophone does away with the need for a journalist to book a fixed satellite facility or to use a heavy (1000 kg) transportable system to go live on the air. All this is required are two shoulder bags weighing less than 5 kg each. The British Broadcasting Corporation (company) British Broadcasting Corporation - (BBC) The non-commercial UK organisation that commissions, produces and broadcasts television and radio programmes. The BBC commissioned the "BBC Micro" from Acorn Computers for use in a television series about using computers. (BBC BBC in full British Broadcasting Corp. Publicly financed broadcasting system in Britain. A private company at its founding in 1922, it was replaced by a public corporation under royal charter in 1927. ) also uses the new videophone technology. Steve Pearce, Organizer of Resources and Development at BBC Newsgathering, said, "Our correspondents situated on the Afghanistan border have been equipped with the satellite videophones. They will come into their own if our reporters need to go into Afghanistan. Logistically, you can move quicker with hand-held equipment and you are no longer a target because of your satellite dish. Although videophone technology does not provide the quality of images that you can expect from full broadcast satellite dishes, by enabling a dial-and-go facility, it allows us to present the news as it happens, which gives our stories higher impact," he continued.
