Abstract: A method for managing requests for input streams associated with at least one incoming network stream received from a network interface. The input streams include at least one of video data, audio data and ancillary data. The method includes receiving a request for an input stream associated with a network stream identifier and determining whether the network stream identifier associated with the input stream matches an existing network stream identifier, the existing network stream identifier associated with at least one existing input stream. The method further includes: if a match is found, associating the input stream and the at least one existing input stream with a common area of memory; and if a match is not found, associating the input stream with a first area of memory that differs from a second area of memory that is associated with the at least one existing input stream.

Abstract: A method and apparatus for compressing a data stream comprising a plurality of pictures are described. A first quantization parameter (QP) from a plurality of QPs is determined, for a static region in a current picture. The plurality of QPs change in accordance with a multi-step change from a start QP to a target QP and each one of the plurality of QPs is to be applied to a respective one from successive static regions in successive pictures. In response to determining, based upon statistics on static region(s) in the current picture which are associated with the first QP, that the first QP is selected, compression of the static region is caused based upon the first QP, and in response to determining that the first QP is not selected, compression of the static region is caused based upon a second QP that is greater than the first QP.

Abstract: Method and system for playing back ancillary data associated with a video stream. At playback, a video stream and an audio stream containing encoded non-audio ancillary data associated with the video stream are received. The audio stream is decoded on a basis of a predefined decoding scheme in order to extract therefrom the non-audio ancillary data associated with the video stream. The video stream and its associated non-audio ancillary data are then both output for playback. This method of playback enables a non-linear editing application that supports only video and audio data to receive, preserve, display to a user for editing purposes, and transmit unsupported non-audio ancillary data, since the latter is in the form of an audio stream.

Abstract: A method and system for displaying graphics on a display of a second module remotely connected with a first module via a data communications medium. A first controller interfaces between a first graphics processor and the first module. A second controller interfaces between a second graphics processor and the first module via the data communications medium and the first controller. The first controller duplicates data returned to the first graphics processor by the first module in response to data requests, and transmits the duplicated data to the second controller. The second controller intercepts data requests by the second graphics processor to the first module, correlates the intercepted requests with the duplicated data received from the first controller and transmits the duplicated data to the second graphics processor based on this correlation. The second graphics processor uses the received duplicated data to generate graphics for display at the second module.

Abstract: There is described a method and system for inputting/outputting multiple data streams of variable widths. Input/output pins are grouped together via a plurality of transfer blocks, each transfer block being controlled by an independent clock. Data streams can therefore be input/output using asynchronous clocks. Two data streams can also be input/output on a single pin using the rising and falling edge of the clock.

Abstract: A system and method for cryptographically securing a graphics system connectable via an external bus to a computing system, the graphics system including a graphics processor, a video memory and a memory controller for controlling the flow of data to and from the video memory. The graphics system further includes a copy engine for copying data between a system memory of the computing system and the video memory, where this copy engine acts independently of the graphics processor of the graphics system. The present invention enables the copy engine of the graphics system to decrypt encrypted data in the course of copying data from the system memory to the video memory and to encrypt unencrypted data in the course of copying data from the video memory to the system memory. Thus, cryptographic protection of secure content may be assured by the graphics system without the excessive usage of its primary resources for this non-graphical purpose.

Abstract: A graphics processing device for converting coefficients in a video data stream from a first type, e.g., frequency-domain, to a second type, e.g., color-domain. The device includes an input for receiving the video data stream including a set of coefficients of the first type and a storage medium holding a data structure containing a first set of coefficients of the second type. The device further includes a processor communicating with the input and with the storage medium. The processor uses the data structure to convert the set of coefficients of the first type to a second set of coefficients of the second type. The device also includes an output in communication with said processor, for releasing an output video data stream including the second set of coefficients of the second type. The same data structure is used repeatedly for each incoming set of coefficients of the first type, thus allowing a transform, such as an IDCT, to be computed efficiently.
