Nokia announced the Mobile TV Headset for DVB-H and WebTV.

The headset handles call reception and volume in a similar way to other mobile headsets, so you won’t miss calls while you’re watching the game. It also features keys for changing channels and music controls for the player on your handset. There’s an app called Mobile TV available for compatible handsets.

there is one thing i don't understand:

the headset works on Symbian^3 devices with the USB-on-the-Go feature like the Nokia N8, C7 or E7. why is the USB-on-the-Go needed?

Mobile TV Headset will be available in  Q4 2010 with a pricetag around €40 +taxes.

One word of caution. While it is expanding, DVB-H coverage is still patchy in many countries. Licensing issues and lack of frequency availability have stalled many projects, though there do appear to be working services in the Netherlands, Russia, New Delhi and Helsinki, for example. Check carefully with local dealers before you buy

to check if DVB-H service is supported in your country, goto DVB-H.org and take look.
