  • Publication number: 20170302918
    Abstract: Systems, methods and apparatuses of processing data of a VR system are disclosed that comprise receiving tracking information which includes at least one of user position information and eye gaze point information. One or more processors may be used to predict, based on the user tracking information, a user viewpoint of a next frame of a sequence of frames of video data to be displayed. Using the prediction, a portion of the next frame of video data to be displayed is rendered at an estimated location in the next frame. A corresponding matching portion in a previously encoded frame is determined based on the estimated location of the portion in the next frame and the portion of the next frame of video data is encoded.

  • Publication number: 20170302972
    Abstract: Virtual Reality (VR) systems, apparatuses and methods of processing data are provided which include predicting, at a server, a user viewpoint of a next frame of video data based on received user feedback information sensed at a client, rendering a portion of the next frame using the prediction, encoding the portion, formatting the encoded portion into packets and transmitting the video data. At a client, the encoded and packetized A/V data is received and depacketized. The portion of video data and corresponding audio data is decoded and controlled to be displayed and aurally provided in synchronization. Latency may be minimized by utilizing handshaking between hardware components and/or software components such as a 3D server engine, one or more client processors, one or more client processors, a video encoder, a server NIC, a video decoder, a client NIC; and a 3D client engine.

    Abstract: Systems, apparatuses and methods of adaptively controlling a cache operating voltage are provided that comprise receiving indications of a plurality of cache usage amounts. Each cache usage amount corresponds to an amount of data to be accessed in a cache by one of a plurality of portions of a data processing application. The plurality of cache usage amounts are determining based on the received indications of the plurality of cache usage amounts. A voltage level applied to the cache is adaptively controlled based on one or more of the plurality of determined cache usage amounts. Memory access to the cache is controlled to be directed to a non-failing portion of the cache at the applied voltage level.

  • Patent number: 9696784
    Abstract: A system, method and a computer program product for processing media content on a media player having direct access to hardware are provided in exemplary embodiments. When the media player is initialized, an operating system is placed into a stand-by mode that decreases power consumption on an electronic device. Instead of the operating system, a hardware pipeline processes media content. A hardware pipeline is dedicated to process a media content based on the media content type. The media content is processed using the dedicated hardware pipeline to reduce the power consumption during processing.

  • Publication number: 20170188051
    Abstract: An encoder encodes pixels representative of a picture in a multimedia stream, generates a first approximate signature based on approximate values of pixels in a reconstructed copy of the picture, and transmits the encoded pixels and the first approximate signature. A decoder receives a first packet including the encoded pixels and the first approximate signature, decodes the encoded pixels, and transmits a first signal in response to comparing the first approximate signature and a second approximate signature generated based on approximate values of the decoded pixels. If a corrupted packet is detected, the multimedia application requests an intra-coded picture in response to the first approximate signature differing from the second approximate signature. The second signal instructs the decoder to bypass requesting an intra-coded picture and to continue decoding received packets in response to the first approximate signature being equal to the second approximate signature.

  • Publication number: 20160295234
    Abstract: Disclosed is a low-complexity and yet efficient lossy method to compress distortion information for motion estimation, resulting in significant reduction in needed storage capacity. A system for implementing the method and a computer-readable medium for storing the method are also disclosed. The method includes determining and storing a distortion value for each trial motion vector in a plurality of trial motion vectors. Each trial motion vector specifies a position of a search region relative to a reference frame. The method further includes compressing each of the distortion values as a fixed number of bits based upon a minimum distortion value amongst the stored distortion values, and re-storing each compressed distortion value in place of its uncompressed value.

  • Publication number: 20160234491
    Abstract: A method and apparatus to maximize video slice size is described herein. The method packs as many macroblocks as possible within a capped-size slice, while preserving user-defined quality constraints. The probability to conform to the maximum slice size constraint may be adjusted according to a user-defined parameter. The method may be integrated into a rate control process of a video encoder. The method predicts whether encoding a macroblock with a quantization parameter exceeds a current slice size constraint. It further predicts whether encoding a given number of macroblocks with a given configuration of quantization parameters exceeds the current slice size constraint. The method then proceeds to encode the current macroblock either on a condition that encoding the given number of macroblocks with the given configuration of quantization parameters falls below the size constraint of the current slice or after determining that a new slice is needed.

  • Patent number: 9118928
    Abstract: A method and system for producing a single view video signal based on a multiview video coding (MVC) signal stream. A MVC signal stream representing multiple spatially related views of a scene, including a base view and at least one dependent view, is decoded to provide multiple decoded video signals representing the spatially related views, with respective portions of the MVC signal stream representing one of multiple temporally adjacent video frames, and the MVC signal stream representing multiple sequences of spatially adjacent video frames. The decoded video signals are processed to provide a processed video signal representing one of the spatially related views using image information from more than one of the decoded video signals. As a result, more image data is used during processing, thereby improving the spatial and temporal image quality.

  • Publication number: 20140354771
    Abstract: An efficient motion estimation method and apparatus for 3D stereo video encoding is described herein. In an embodiment of the method, an enhancement layer motion vector for a frame is determined by obtaining a motion vector of a co-located macroblock (MB) from the same frame of a base layer. The motion vectors of a predetermined number of surrounding MBs from the same frame of the base layer are also obtained. A predicted motion vector for the MB of the frame in the enhancement layer is determined using, for example, a median value from the motion vectors associated with the co-located MB and the predetermined number of surrounding MBs. A small or less than full range motion refinement is performed to obtain a final motion vector, where full range refers to the maximum search range supported by an encoder performing the method.

  • Publication number: 20120223938
    Abstract: A system and method for providing user control of the projection of two-dimensional (2D) image information within the three-dimensional (3D) display space of a 3D-capable display device. Advantageously, the system and method disclosed herein allow a user to view 3D video even when the source video includes 2D content, by allowing the user to adjust the z-axis position of the 2D content, thereby causing the 2D content to be projected at a user-specified image depth within 3D space. The user can adjust the z-axis position of the 2D content in real time while contemporaneously viewing the imagery, e.g., via a remote control, and such adjustment can be stored for later use when similar or other 2D content is being viewed.
