摘要： 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, and graphics input. The chip includes a single polyphase filter that preferably provides both anti-flutter filtering and scaling of graphics. Anti-flutter filtering may help reduce display flicker due to the interlaced nature of television displays. The scaling of graphics may be used to convert the normally square pixel aspect ratio of graphics to the normally rectangular pixel aspect ratio of video.

摘要： 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, graphics input and audio input simultaneously. The system includes a video decoder having a chroma-locked sample rate converter. The chroma-locked sample rate converter converts the samples to those taken at a sample rate that is a multiple of the chroma subcarrier frequency and that is locked to chroma bursts of the analog video signal in a control loop. The video decoder also includes a line-locked sample rate converter that receives samples at a multiple of the chroma subcarrier frequency and converts the samples to samples with a sample frequency that is a multiple of the horizontal line rate of the video input. The line-locked sample rate converter measures the horizontal line rate to an accuracy of a fraction of a pixel and adjusts the sample rate and phase of the line-locked sample rate converter to produce accurate line-locked samples. The time base corrector receives samples at the output of the line-locked sample rate converter and provides samples synchronized to the display clock for reducing undesirable artifacts such as jitter.

摘要： A video, audio and graphics system uses multiple transport processors to receive in-band and out-of-band MPEG Transport streams, to perform PID and section filtering as well as DVB and DES decryption and to de-multiplex them. The system processes the PES into digital audio, MPEG video and message data. The system is capable of decoding multiple MPEG SLICEs concurrently. Graphics windows are blended in parallel, and blended with video using alpha blending. During graphics processing, a single-port SRAM is used equivalently as a dual-port SRAM. The video may include both analog video, e.g., NTSC/PAL/SECAM/S-video, and digital video, e.g., MPEG-2 video in SDTV or HDTV format. The system has a reduced memory mode in which video images are reduced in half in horizontal direction only during decoding. The system is capable of receiving and processing digital audio signals such as MPEG Layer 1 and Layer 2 audio and Dolby AC-3 audio, as well as PCM audio signals. The system includes a memory controller. The system includes a system bridge controller to interface a CPU with devices internal to the system as well as peripheral devices including PCI devices and I/O devices such as RAM, ROM and flash memory devices. The system is capable of displaying video and graphics in both the high definition (HD) mode and the standard definition (SD) mode. The system may output an HDTV video while converting the HDTV video and providing as another output having an SDTV format or another HDTV format.

摘要： A display engine of a video and graphics system includes one or more processing elements and receives graphics from a memory. The graphics data define multiple graphics layers, and the processing elements process two or more graphics layers in parallel to generate blended graphics. Alpha values may be used while blending graphics. The processing elements may be integrated on an integrated circuit chip with an input for receiving the graphics data and other video and graphics components. The display engine may also include a graphics controller for receiving two or more graphics layers in parallel, for arranging the graphics layers in an order suitable for parallel processing, and for providing the arranged graphics layers to the processing elements. The blended graphics may be blended with HDTV video or SDTV video, which may be extracted from compressed data streams such as an MPEG Transport stream.

摘要： 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, and graphics input. The chip includes a single polyphase filter that preferably provides both anti-flutter filtering and scaling of graphics. Anti-flutter filtering may help reduce display flicker due to the interlaced nature of television displays. The scaling of graphics may be used to convert the normally square pixel aspect ratio of graphics to the normally rectangular pixel aspect ratio of video.

摘要： 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 system may use anti-aliased text and graphics to provide high quality display of graphical elements, or glyphs, which represent an image of a character of text or graphics, on television and other displays. The graphical elements may be superimposed over live video or arbitrary graphics imagery.
