What is IVTV?

The [IVTV] project started in early 2003 with the primary goal of providing a Linux Open Source driver for series of Conexant based TV cards. The project is developing a clean room driver for cards based on the iCompression iTVC15 or Conexant CX23415/CX23416 MPEG codec. A clean room implementation is needed as Conexant will only release the data sheet for the iTVC codec under a Non-disclosure agreement.

At its current state, many iTVC based cards are usable with this driver, and work continues to remove bugs, support more cards and to develop towards V4L2 compliance.

Functioning IVTV cards

[Hauppauge] make a range of PCI cards, some of which are usable with this driver. The IVTV driver works with the following Hauppauge range:

PVR-150[link] includes a hardware MPEG-2 encoder.
PVR-250[link] includes a hardware MPEG-1 and MPEG-2 encoder.
PVR-350[link] includes a hardware MPEG-2 encoder and decoder with video out.
PVR-500MCE[link] includes a dual tuner and dual MPEG encoder.

[AVerMedia] produce the [AVerMedia M179 AVerTV] card that features an MPEG encoder which is usable with the unstable version of IVTV driver.

Development

The IVTV drivers are in constant development, and like in many open source projects there is a stable/unstable release system. Some cards are only supported by the unstable drivers, and often only with a particular unstable version.

Current development source can be found [here].
