Abstract
A video controller broadcasts input video through a premises media, such as a coaxial cable to one or more premises televisions or television channels. When a PC provides the input video, a mode change may occur to direct the video to the PC monitor or to the broadcast output. The video resolution of the PC is set to provide a desired digital television resolution with broadcast video. An audio driver may be used to provide USB audio output from the PC. When the PC monitor or broadcast output is selected for video output, the non-selected output is disabled or provided with a video indication that another video output is active. An EDID can be captured from the PC or PC monitor to assist with mode changes and setting PC video resolution. The input video may be provided directly from a digital video source and broadcast to selected televisions or channels.
