Abstract: A system and methods are shown for handling multiple target memory requests. Memory read requests generated by a peripheral component interconnect (PCI) client are received by a PCI bus controller. The PCI bus controller passes the memory request to a memory controller used to access main memory. The memory controller passes the memory request to a bus interface unit used to access cache memory and a processor. The bus interface unit determines if cache memory can be used to provide the data associated with the PCI client's memory request. While the bus interface unit determines if cache memory may be used, the memory controller continues to process the memory request to main memory. If cache memory can be used, the bus interface unit provides the data to the PCI client and sends a notification to the memory controller.

The interlink module selects pixels of the frames from the processed data of one of the processors based on a predetermined pixel characteristic and outputs the frames that include the selected pixels.

Abstract: A method, system, and software for improved display of multiple media channels are disclosed herein. A system may be used to select, independent of direct user input, a subset of a plurality of media channels based on a user's viewing pattern. The system can include one or more media sources, a media processing system, and a display device, as well as a method for its use. The media processing system receives a plurality of media channels from the one or more media sources. One or more attributes associated with each media channel are compared with a user's viewing pattern determined independent of direct user input by the media processing system. A surf list is generated from the plurality of media channels, where the surf list includes a subset of the plurality of media channels having one or more attributes that are congruent with the user's viewing pattern. A portion, such as a still image, of each media channel in the surf list is output to an output device, such as a display device or storage device.

Abstract: Embodiments of a method and system for intra-prediction in decoding video data are described herein. In various embodiments, a high-compression-ratio codec (such as H.264) is part of the encoding scheme for the video data. Embodiments pre-process control maps that were generated from encoded video data, and generating intermediate control maps comprising information regarding decoding the video data. The control maps indicate which units of video data in a frame are to be processed using an intra-prediction operation. In an embodiment, intra-prediction is performed on a frame basis such that intra-prediction is performed on an entire frame at one time. In other embodiments, processing of different frames is interleaved. Embodiments increase the efficiency of the intra-prediction such as to allow decoding of high-compression-ratio encoded video data on personal computers or comparable equipment without special, additional decoding hardware.

Abstract: A system and method for improved antialiasing in video processing is described herein. Embodiments include multiple video processors (VPUs) in a system. Each VPU performs some combination of pixel sampling and pixel center sampling (also referred to as multisampling and supersampling). Each VPU performs sampling on the same pixels or pixel centers, but each VPU creates samples positioned differently from the other VPUs corresponding samples. The VPUs each output frame data that has been multisampled and/or supersampled into a compositor that composites the frame data to produce an antialiased rendered frame. The antialiased rendered frame has an effectively doubled antialiasing factor.

Abstract: An asymmetrical IO method and system are described. In one embodiment, a host device includes shared resources for data synchronization of the host device and a client device. The shared resources include a shared phase interpolator. In an embodiment, data lines between the host and client are also used to transmit phase information from the client device to the host device, obviating the need for additional, dedicated lines or pins.

Abstract: In various embodiments, dedicated mask pins are eliminated by sending a data mask on address lines of the interface. A memory controller receives a request for a memory write operation from a memory client and determines the granularity of the write data from a write data mask sent by the client. Granularity, as used herein, indicates a quantity of write data to which each bit of the received write data mask applies. In an embodiment, the memory controller generates a particular write command and a particular write data mask based on the granularity of the write data. The write command generated is typically the most efficient of several write commands available, but embodiments are not so limited. The write command is transmitted on command lines of the interface, and the write data mask is transmitted on address lines of the interface.

Abstract: The invention provides techniques for separating luma and chroma signal components in a composite SECAM video signal. During reception, the SECAM video signal is split into luma and chroma output. The amplitude of the chroma carrier is monitored during reception. If the chroma carrier amplitude is greater than a threshold, the value of the chroma output can be reduced. Also, if the chroma carrier amplitude is greater than another threshold, a portion of the chroma carrier can be added to the luma; or the trap band of the band-trap filter for extracting luma from the composite video can be reduced. The respective amount of the reduction in the chroma output and the increase in the luma output are independently determined but both may proportional to the magnitude of the deviation in the chroma carrier amplitude from the different thresholds.

Abstract: A system and method for providing playback of multiple video streams simultaneously is shown and described. A priority is assigned to individual windows of a plurality of windows used for playback of the video streams. A current window being accessed by a user is assigned a higher priority than nonactive, or background, windows. Playback characteristics, such as video resolution, transparency, and audio volume, are reduced in the playback of videos presented in nonactive windows in relation to video played in the active window. Accordingly, a user's attention may be drawn more to the active window than to the nonactive windows, while allowing the video and audio data in the nonactive windows to be provided to the user.

Abstract: A system includes a first communication device and a second communication device. The first communication device includes a programmable region. The programmable region of the first communication device is programmed so that an associated signal includes a number of preamble cycles.
