Embodiments of the invention are generally directed to conversion of multimedia data streams for use by connected devices. An embodiment of a method for processing data includes receiving a data stream in a first multimedia data format at a first device, and inserting a replacement video portion into the received data stream to generate a modified multimedia data stream in a second multimedia data format. The modified data stream is provided to a second device coupled to the first device.

Conversion of multimedia data streams for use by connected devices

A jitter correction apparatus and method are disclosed. In one embodiment, the apparatus has a rising edge corrector to receive a jittered signal and to output a jitter corrected rising edge of the jittered signal. The apparatus may also have a falling edge corrector to receive the jittered signal and to output a jitter corrected falling edge of the jittered signal. The jitter correction apparatus may include an output device to receive the jitter corrected rising edge, to receive the jitter corrected falling edge, and to output a jitter corrected signal.

Digital display jitter correction apparatus and method

A text enhancement unit is introduced in order to alleviate the degradation of text characters on computer or television displays. The text enhancement unit uses an enhancement process to regain uniformity and intensity that may be lost during image processing. The text enhancer unit may be placed between an image processing unit such as a scaler, de-interlacer, or DSP, and a computer or television display to improve the quality of text characters that may have become degraded by image processing performed by the image processing unit. In one embodiment, the text enhancer unit improves contrast by multiplying pixel intensity by an intensity multiplier. In a second embodiment, the text enhancer unit improves contrast using a threshold operation which outputs either a very high or very low intensity pixel. In an third embodiment, the text enhancer unit improves contrast using a threshold operation which outputs either a very low intensity pixel or a pixel multiplied by an intensity multiplier. In a fourth embodiment, the text enhancer unit improves contrast using a threshold operation which outputs either an unchanged pixel or a pixel multiplied by an intensity multiplier. In a fifth embodiment, the text enhancer unit improves contrast using a dual threshold operation which outputs either a very low intensity pixel, a very high intensity pixel, or an unchanged pixel.

Video/graphics text mode enhancement method for digitally processed data

A communication system including a transmitter, a receiver, and a serial link, in which encoded data (e.g., video, audio, and optionally also other auxiliary data) are transmitted from the transmitter to the receiver. The serial link can but need not be a TMDS or TMDS-like link. In typical embodiments, packets of encoded audio data are transmitted over each of one or more channels of the link during data islands between bursts of encoded video data, a pixel clock is transmitted over the link, and the receiver regenerates a clock for the audio data using time code data in the packets and the pixel clock. Other aspects of the invention are transmitters for transmitting encoded data and a pixel clock over a serial link, receivers for receiving such data and pixel clock and performing audio clock regeneration, and methods for transmitting encoded data and a pixel clock over a serial link and performing clock regeneration using the transmitted data and pixel clock.

Method and apparatus for regenerating a clock for auxiliary data transmitted over a serial link with video data

A communication system including a transmitter, a receiver, and a serial link, in which encoded data (e.g., video, audio, and optionally also other auxiliary data) are transmitted from the transmitter to the receiver. The serial link can but need not be a TMDS or TMDS-like link. In typical embodiments, packets of encoded audio data are transmitted over each of one or more channels of the link during data islands between bursts of encoded video data. Other aspects of the invention are transmitters for use in encoding data for transmission over a serial link, receivers for receiving such data, and methods for sending encoded data over a serial link.

The invention relates to computer graphics and computer imaging on a video display, and includes the dynamic detection of video windows and graphical images overlapping one another. A display processor identifies differences between typical video and graphics data sources to detect the edges of video windows. By detecting the edges of active video windows within a graphics image, a display processor may uniquely adjust image characteristics of an exposed video window. These characteristics include, for example, hue, brightness, intensity and contrast.
