Abstract: A reflective wire grid polarizer (WGP) can include an array of wires 12 on a face of a substrate 11, with channels 15 between adjacent wires 12. The wires 12 can have certain characteristics for WGP performance, such as index of refraction, alternating high/low index continuous thin films, thickness of layer(s), duty cycle, reflective rib shape, a curved side of transparent ribs 21 or 32, aspect ratio, or combinations thereof.

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.

Abstract: A video controller selects a channel for premises broadcasting to a premises television based on a fast scan of signal strength in channels available over a premises media. The signal strength of certain filtered channel frequencies can be evaluated to determine if a channel is occupied. Unoccupied channels can be ranked in relation to nearby occupied or unoccupied channels. The nearby channels may be ranked in terms of the signal strength content in relation to the channel being evaluated. The video controller can select an unoccupied channel with an optimal ranking to permit premises broadcasting with reduced interference or conflict with other channels.
