Sony PlayTV dual tuner DVB-T
It is supported under Linux.
This device, vendor id 0x1415, product id 0x0003, is based around the DiBcom STK7070PD reference design and has a STK7070PD frontend and two DIB7070p tuners.
It has two distinct advantages over its sibling devices:
- the use of a single external antenna connected, which is internally used to drive both tuners, rather than requiring an external splitter
- its packaging in a well designed and sufficiently shielded external casing that reduces any risk of electromagnetic interference
See Wikipedia  for more info on the device itself.
Making it Work
You will need the dvb-usb-dib0700-1.20.fw firmware file in /lib/firmware or the relevant place for your distribution.
It requires the dib0700 driver, updated to include support for this variant of the reference design.
Support is available via the original patch for the 188.8.131.52 kernel or from the v4l-dvb tree since changeset 10824. A patch has also been generate against the 2.6.28-11 kernel package in Ubuntu jaunty and a bug raised for its inclusion in the release here.
Using Mercurial and following the How to Obtain, Build and Install V4L-DVB Device Drivers instructions is the recommended way to obtain the driver until it has been included in an official kernel release.
