research into platforms for broadcasting music programmes

I have been looking into digital radio through the television as most televisions have a wide range of radio stations built into them.
You will be able to recieve all BBC channels including BBC 1xtra and BBC 6 music. There are other channels such as absolute radio, Kiss fm and Smas hits.
The radio stations that feature on the televsion channels are mainly music based , and there is very little chat. Excluding BBC 5 live.
Radio on digital television was introduced in 2006 when plasma displays where introduced.
