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： Herein described is a method and system of vertically filtering a graphics image such that an enhanced image is provided to a display. Filtering of the graphics image may be accomplished by using one or more window descriptors. The method may be implemented by computing a weighted average of one or more pixel intensities. The system may comprise a memory, a processor, and a graphics engine. The graphics engine may comprise a graphics blender. The graphics blender may comprise one or more multipliers and one or more adders. The processor may execute software resident in the memory, such that the one or more window descriptors may be used to compute the weighted average.

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 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.
摘要翻译：在用于控制电视显示器的机顶盒中使用图形集成电路芯片。图形芯片同时处理模拟视频输入，数字视频输入，图形输入和音频输入。系统可以使用反锯齿的文本和图形来提供在电视和其他显示器上表示文本或图形的图像的图形元素或字形的高质量显示。图形元素可以叠加在实时视频或任意图形图像上。
