Patent number: 6738072Abstract: 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.Type: GrantFiled: November 9, 1999Date of Patent: May 18, 2004Assignee: Broadcom CorporationInventors: Alexander G. MacInnis, Chengfuh Jeffrey Tang, Xiaodong Xie, James T. Patterson, Greg A. Kranawetter

Patent number: 6721837Abstract: A graphics display system integrated circuit is used in a set-top box for controlling a television display. The graphics display system processes analog video input, digital video input, and graphics input. The system incorporates a unified memory architecture that is shared by the graphics system, a CPU, and other peripherals. The unified memory architecture uses real time scheduling to service tasks. Critical instant analysis is used to find a schedule for memory usage that does not affect memory requirements of real time tasks while at the same time servicing non-real-time tasks as needed.Type: GrantFiled: December 17, 2002Date of Patent: April 13, 2004Assignee: Broadcom CorporationInventors: Alexander G.

Patent number: 6700588Abstract: 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 blends graphics and video information by various graphics windows using alpha values for the windows, alpha values per pixel, or both.

Patent number: 6018369Abstract: An arrangement and method for receiving a compressed video stream and generating a decompressed video signal and closed caption data therefrom employs a video decoder a video decompressor that decompresses the compressed video stream to generate a decompressed video signal. The video decoder has a closed caption data embedder that produces closed caption data contained in the compressed video stream for embedding into a video output signal of the video decoder. A single video signal output port is coupled to the video decompressor and the closed caption data embedder and produces the video output signal which includes the decompressed video signal and the embedded closed caption data.Type: GrantFiled: March 21, 1996Date of Patent: January 25, 2000Assignee: Samsung Electronics Co., Ltd.Inventor: James T.

Patent number: 5923379Abstract: A system for providing a user controllable picture-in-picture formatted signal to a television is provided with a fast modem that interconnects the system with a computer network, such as the Internet. In order to allow a user to interact with the Internet, yet still enjoy video programming, the system has a picture-in-picture selection that a user controls to determine which video source (e.g., digital satellite signal, digital video disk signal, Internet graphics) will form the main picture displayed on the television, and which will form the picture-in-picture. A conventional television may be used with the system to display the signal, since it is already formatted in a picture-in-picture format at the output of the system.Type: GrantFiled: December 2, 1996Date of Patent: July 13, 1999Assignee: Samsung Electronics Co., Ltd.Inventor: James T.
