Abstract: Various codecs and methods of using the same are disclosed. In one aspect, a method of processing video data is provided that includes encoding or decoding the video data with a codec in aggressive deployment and correcting one or more errors in the encoding or decoding wherein the error correction includes re-encoding or re-decoding the video data in a non-aggressive deployment or generating a skip picture.

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.

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.

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.

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.

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.

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.

Abstract: A method and system are provided for navigating and selecting objects within a 3D video image by computing a depth coordinate based upon two-dimensional (2D) image information from left and right views of such objects. In accordance with preferred embodiments, commonly available computer navigation devices and input devices can be used to achieve such navigation and object selection.

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.
