Virtual studios – the BBC's experience

When a broadcaster is faced with any new technology there is initially a period of uncertainty. Is it just an engineering toy, or will it radically alter the production process? Such is the dilemma over virtual studios.

The Author describes the facets of virtual studio production which the BBC has found hardest to adapt and get right, and puts forward some ideas on where improvements could be made by the developers of such systems.

Testing the new television tape formats for news and sport
R.A. Chalmers (100 KB)

 

Last year, two new digital tape recording formats were launched, aimed at the news, current affairs and sports sectors of television production: Sony Betacam SX and Panasonic DVCPRO. In co-operation with the manufacturers, EBU Group P/DTR carried out extensive tests on these new formats and their reports on the tests became available in April of this year. These will be made available only to EBU Members.

In this article, the Author presents a synopsis of the EBU reports on these two new tape formats.

Towards the next generation of DAB receivers
F. van de Laar, N. Philips, J. Huisken (123 KB)

 

The first DAB receivers which accorded with the DAB European Telecommunication Standard became available in 1995. These were based on either a DAB channel-decoder chipset from the JESSI project, or on general-purpose DSPs. For a consumer product, the complexity of these early DAB receivers was much too high.

This article describes the features of the next generation of DAB receivers, which are due to be launched at the Berlin IFA in late August. These new receivers will be based on a second generation of channel-decoder chipsets, as developed within the JESSI AE-14 and AE-89 projects. Not only will they be much smaller (and cheaper) than the earlier models from 1995, the new generation of receivers will also support DAB transmission mode IV and the reception of low bit-rate MPEG-2 speech.
