The Engineering Channel
DTG Testing Ltd manages the operation of the UK's Engineering Channel, a facility available to receiver manufacturers for the upgrading of the software resident in DTT products deployed in the UK.
All major receiver manufacturers supplying the UK market have service agreements with DTG Testing for access to the Engineering Channel.
The Engineering Channel is carried on the main BBC multiplex, which has the greatest service area of the six multiplexes in the UK. It is supported by the engineering resources of BBC Broadcast to provide a reliable 24-hour service.
In addition, the pre-transmission testing of submitted downloads carried out by DTG Testing ensures that no problems are likely to occur during live transmissions. In addition to analysing each new download file, closed circuit tests are made with over 50 samples of the receiver products deployed in the UK.
DTG Testing manages the scheduling of the over-air downloads to ensure that all manufacturers have access to the capacity available with little delay and adequate transmission durations. The retailers and installers section of the DTG web site carries details of the download transmissions for the current and following week.
For those companies that do not have a facility for building the Object Carousels used to carry the download files, DTG Testing offers a service of carousel construction.
Liaison between DTG Testing and the users of the Engineering Channel is maintained through regular Plenary Meetings and a Technical Subgroup has been formed to handle technical issues affecting the Channel and its development.
