Screen Subtitling Systems has sold a new transcoding system to Siemens IT Solutions and Services that will be used as part of a new coding and multiplexing service for the BBC.

Screen's equipment provides the corporation with the subtitle component of the CCM project (Centralised Coding and Muxing) through additional DVB (Digital Video Broadcasting) subtitling and transcoding technology.

Supporting the BBC's centralised coding and multiplexing initiative, Screen's technology converts Teletext subtitles into the DVB format required for broadcast - a process known as transcoding.

As part of an agreement with Siemens IT Solutions and Services worth£1.7 million, Screen has delivered complete transcoding systems comprising hardware and Screen's Polistream software pre-installed and configured to the BBC's specific requirements.

Siemsns has overall responsibility for designing, building and operating a new coding and multiplexing infrastructure for the broadcaster through to 2015 as part of digital switchover.

Commenting on the choice of Screen, Graham Whiting, principal project manager at Siemens IT Solutions and Services, explained: “What gave Screen the edge was not just that they satisfied all the immediate requirements, but they could also demonstrate that their system was flexible and could be expanded to cover future potential requirements.”
