Introduction

Some channels broadcast a tv signal which is not standards compliant. It usually lacks sync pulses, gets inverted at random times and even may include disinformation. Those signals can't be comfortably viewed on a normal television set. The Brooktree 87[89](A) chip has a special mode in which it doesn't get confused because of missing sync signals. This program enables this mode, very much alike cabletv, and takes special measures to keep the image stable and adjust for the inversion. The output of this program appears on standard output in YUV4MPEG2 format, and can, for example, be fed to MPlayer.

This program is free software. See COPYING for details.

Note that some countries might have draconian laws which may require you to get some kind of permission from the broadcaster before you may use this program legally. Consult a lawyer if you are in doubt.

Here is a link to the excellent program cabletv, without which cc2y4m would have never been possible. The output of this program can, for example, be used as input to MPlayer and the mjpeg tools.
