摘要:
A system and method that provide reduced latency in a video signal processing system. Various aspects of the present invention may comprise transmitting a first video information stream representative of a unit of video information. For example, the transmitted first video information stream may correspond to a video channel. A second video information stream representative of the unit of video information may be transmitted simultaneously with the first video information stream. The second video information stream may also, for example, correspond to the video channel. Various aspects of the present invention may comprise receiving a plurality of simultaneously transmitted video information streams. A video information stream of the plurality of received video information streams may be identified that, when processed, is expected to result in the lowest latency in presenting the unit of video information to the user. The identified video information stream may then be so processed.

In a computing system, a method and system for a thin client and blade architecture are provided. A blade may generate video, audio, and peripheral control information that may be transmitted to a thin client (TC) by utilizing a video encoder, an audio bridge, and a peripheral bridge. Communication between the blade and the TC may occur based on a communication protocol that may operate independently of an operating system and/or applications running on the blade. The video encoder may dynamically compress the video information according to network capacity and/or video content and may dynamically select from various compression algorithms. The blade may configure and manage operations that interface with the TC. The TC may comprise a video decoder, a transceiver, a processor, a video display bridge, an audio bridge, and a peripheral bridge and may be adapted to communicate with peripheral devices.

Methods and systems for processing video information are disclosed herein and may comprise calculating at least one vertical gradient of a plurality of adjacent pixels within a current field. A two-field difference may be calculated between a plurality of pixels within a first field and a corresponding plurality of pixels within a second field. At least one pixel may be deinterlaced within the current field based at least in part on the calculated at least one vertical gradient and the calculated two-field difference. The two-field difference may indicate an amount of motion between the plurality of pixels within the first field and the corresponding plurality of pixels within the second field. Phase shifting may be applied to at least one of the plurality of pixels within the first field and the corresponding plurality of pixels within the second field to effect in-phase alignment.

Presented herein are system(s), and method(s), for interlaced to progressive conversion using weighted average of spatial interpolation and weaving. In one embodiment, there is presented a deinterlacer for deinterlacing. The deinterlacer comprises a first circuit and a second circuit. The first circuit measures weave artifacts between an alternate field and a field for a pixel at a pixel position in the alternate field. The second circuit generates a pixel value for the pixel position in the field, where the pixel value is the weighted average of the pixel, and an interpolated value from two or more pixels from the field, where the weighted average is a function of the weave artifacts.

Methods and systems for processing a video signal are disclosed herein. Pixels may be interpolated utilizing at most two passes. During a first of the two passes, an aligned sub-pixel value may be interpolated utilizing a plurality of integer pixel values, if the aligned sub-pixel value is horizontally or vertically aligned with the plurality of integer pixel values. During a second of the two passes, a non-aligned sub-pixel value may be interpolated utilizing the interpolated aligned sub-pixel value, if the non-aligned sub-pixel value is not horizontally or vertically aligned with the plurality of integer pixel values. The aligned sub-pixel value may be interpolated utilizing 4-tap filtering of the integer pixel values.

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.

A system and method for determining whether to process a signal using three-dimensional comb filtering. Various aspects of the present invention may comprise method steps and system components that generate an inter-frame chroma signal. Various aspects may generate a filtered inter-frame chroma signal by removing a band of frequency components from the inter-frame chroma signal that generally corresponds to chroma signal components.

Various aspects may comprise method steps and components that generate inter-frame and intra-frame luma signals. Various aspects may generate filtered inter-frame and intra-frame luma signals by removing frequency components from the inter-frame and intra-frame luma signals, respectively, that fall outside a frequency band near the chroma sub-carrier frequency. Various aspects may analyze the filtered inter-frame and intra-frame luma signals to determine whether three-dimensional comb filtering may be appropriate.
