摘要:
A television on a chip (TVOC) system that provides a cost effective approach for providing television functionality on a single integrated circuit chip is disclosed. A TVOC includes the functionality necessary to receive and display television signals in a variety of input and output formats. A TVOC can be used in set-top boxes for cable and satellite television, or directly within a television. All functionality provided can be provided on a single integrated circuit. TVOC includes a data transport module, an IF demodulator, a digital audio engine, an analog audio engine, a digital video engine, and an analog video engine. The TVOC also includes three sets of interfaces including output interfaces, control interfaces and ancillary interfaces. Further features and embodiments provide enhanced functionality and increased efficiencies.

A graphics integrated circuit chip is used in a set-top box for controlling a television display. The graphics chip processes analog video input, digital video input, a graphics input and an audio input simultaneously. The chip incorporates a unified memory architecture that provides a high level of system performance while conserving memory bandwidth and chip size. Video and graphics scaling capabilities as well as anti-flutter filtering capability are provided.

Provided is a system and method for performing CRC analysis in a video test bench. An exemplary system includes a memory configured for storing a required number representative of the data fields to be analyzed. A module is coupled at least indirectly to the memory and configured for (i) receiving an input data stream, (ii) performing cyclic redundancy check (CRC) analysis of the received data stream, and (iii) producing an output representative of an actual number of received data fields analyzed. The input data stream includes synchronization markers defining boundaries of each of the received data fields. Next, a comparator is configured for (i) comparing the required number and the actual number and (ii) producing a disabling signal when the actual number matches the required number. A detector is coupled to the comparator and configured for (i) receiving the input data stream and sensing a presence of the synchronization markers, (ii) receiving the disabling signal, and (iii) disabling the CRC module when the disabling signal is received.

摘要:
Aspects of the invention may include a method updating a color look-up table (CLUT) for a next line of graphics before a current line of graphics has been completely read out of a graphics FIFO and assigned color pixel values. The method may include the step of formatting or arranging the CLUT into a plurality of sub-CLUTs. Each one of the sub-CLUTs may include pixel color values for each one of a plurality of pixels which may include a line of the graphics image data. Pixel color values may be read from within a first selected sub-CLUT, the first selected sub-CLUT comprising pixel color values for a first line of the graphics image data. The read pixel color value may be applied to the current first line of the graphics image data. While the read pixel color value is being applied to the current first line, pixel color values for a second selected sub-CLUT may be updated. The second selected sub-CLUT may include color pixel values for a second line of the graphics image data.
