A wireless wearable video headset device useful for viewing and listening to multimedia content. In one embodiment, the device operates by receiving a digital encoded audio / video signal from a host device of a Bluetooth™ wireless connection, the Bluetooth™ connection established via a Serial Port Profile (SPP), and the digital video signal having been previously compressed with Windows Media Video (WMV) or H. 264 compliant compression. The received digital audio / video signal is then forwarded over a Universal Serial Bus (USB) connection to an internal processor which then decompressed video content in the digital video signal to generate a component video signal that is suitable for handling by a display driver.

To permit the use of a single remote control device in an AV system that can supply incompatible video signals, a switch box (18) receives composite and S-video signals from an AV receiver, transforming these signals into the component video domain, and also receives component video signals from, e.g., a DVD player (14), with the output of the switch box being displayed on a television (16), and also receives a signal from a DVI source (101). The synchronization portion of the component video signal from the DVD player is sent to one of the input ports (14) of the AV receiver as a trigger signal for comparison thereof with the synchronization signal in the switch box (18). When a user selects the AV receiver input port into which the trigger signal is input, the sense signal at the switch box (18) is identical to the synchronization signal of the component video, and the switch box (18) consequently sends the component video to the television (16). Otherwise, one of the video signals from the AV receiver (14) is sent to the television (16). If a DVI display (114) is present, analog signals fare converted and scaled to produce a DVI signal suitable for display (114).

A digital video synchronizer for providing parallel and coordinated synchronization paths for decoded and undecoded video. Processing is added for a parallel path in a synchronization memory that bypasses the comb filter and video decoder circuitry to allow a digitized composite video to pass through unchanged. This parallel path is coordinated with the decoder path to provide features of both a composite video synchronizer and a digital component decoder / synchronizer with time base corrector. A digital encoder transforms component video back into modulated composite video. The digital encoder generates a synchronizing and color burst signal to replace the sync and burst signals of the composite video signal. The synchronized composite and synchronized encoded signals are adjusted in timing, gain and DC offset to match one another so that the signals can be faded, mixed, or multiplexed without detectable differences. A multiplexer switches between the encoded version of the video signal and the undecoded version.

An information handling system outputs plural types of TV out signal formats from a common TV out port by configuring graphics card digital-to-analog converters to generate a selected TV out signal and communicating the TV out signal through an appropriate adapter cable. For instance, graphics card VGA digital-to-analog converters are selectively configured to output component video with three converters, super video with two converters or composite video with one converter. The TV out signal is outputted at a super video port with component and composite video communicated through an adapter cable having a super video connector at one end and a component video connector at another end. Automated selection of the TV out signal format is performed by detecting the number of active TV out signals, three for component video, two for super video and one for composite video.

A chroma-decoder 1 has two SRCs 17 and 21. The first SRC 17 performs down-conversion, changing the sampling rate of a composite video signal sampled with a system clock signal Cs to the sampling rate (14.3 MHz) of an NTSC signal. The signal generated by the SRC 17 is output in synchronism with the system clock signal Cs. The signal is then divided into a luminance signal Y and a color-difference signal C, which are subjected to chroma decoding. The second SRC 21 performs down-conversion, changing the sampling rate of the luminance signal and color-difference signal of the NTSC signal to the sampling rate (13.5 MHz) of an ITU-R601 standard.

Programmable video generation and analyzer including a video asset for generating video signals having a primary composite video module for producing different types of a primary video signal and outputting the primary video signal via output channels, and a secondary video source module for producing a secondary composite video signal and outputting the secondary composite video signal via output channels. The secondary video source module produces the secondary composite video signal in an identical or different format than the primary video signal and different than the primary video signal. An NTSC / PAL converter is included, for example, as part of the secondary video source module, for generating video in NTSC format and PAL format. The NTSC / PAL converter accepts a stream of data from the primary composite video module and the secondary video source module and converts it into Composite Baseband Video, Y / Pr / Pb Component Video, Y / C Video (S_Video) or RGB Video.

A video device comprises: a video signal processor generating a standard definition video signal at least having a composite signal and a high definition component video signal; an outputting unit outputting the standard definition video signal or the high definition component video signal to a cable to be connected; a discriminating unit discriminating a kind of cable connected to the outputting unit; and a switch allowing the outputting unit to selectively output the standard definition video signal and the high definition component video signal on the basis of the discrimination result of the discriminating unit. When the discriminating unit determines that the cable connected to the outputting unit is a cable for a high definition signal, the switch allows the outputting unit to output the high definition component video signal.

A simplified Y / C separation circuit separates a composite video signal into a first luminance signal and a first color signal without subjecting the composite video signal to three-dimensional processing. A color demodulation circuit color-demodulates the first color signal into a first color difference signal. A three-dimensional processing portion removes an image quality debasing component by performing three-dimensional processing with respect to the first luminance signal and the first color difference signal or a second luminance signal constituting a component video signal and a second color difference signal. A selector selectively supplies the first luminance signal and the first color difference signal or the second luminance signal and the second color difference signal to the three-dimensional processing portion.
