    Abstract: Apparatus and methods for decoding streaming data containing one or more coded pictures in which each picture contains a plurality of slices and each slice containing a plurality of macroblocks are disclosed. A first decoding subtask is performed on all macroblocks in the coded picture or a section thereof. After performing the first decoding subtask on all macroblocks in the coded picture or a section thereof, a second decoding subtask is performed on all the macroblocks in the coded picture or section thereof. One or more of the first and second tasks includes examining a slice or macroblock within the coded picture to determine if there are any errors, and if an error is present, handling the error.

    Abstract: A video transcoding method is provided for transcoding a first signal stream compressed by a first coding scheme to a second signal stream compressed by a second coding scheme. The method employs an adaptive frame rate and a joint temporal-spatial rate control technique, such that the overall quality of compressed MPEG video can be significantly enhanced when the transcoding is controlled in the joint temporal (picture or frame rate) and spatial (quantization) domains. One embodiment considers transcoding from high bit rate video with larger image size (e.g. 4CIF/4SIF, CIF) coded by one coding technique, e.g., MPEG-2 to a lower bit rate video with smaller image size (e.g. CIF, QCIF) coded by the same or another coding technique, e.g., MPEG-4.

    Abstract: A method and apparatus of Intra mode coding for a scalable video coding system are disclosed. For a current Intra-coded block in the enhancement layer (EL), predictive coding is applied to the current Intra mode based on the base layer (BL) coding mode associated with the co-located block in the BL and neighboring coding modes associated with neighboring blocks of the current block in the EL. The neighboring blocks of the current block in the EL comprise a left block adjacent to a left side of the current block and a top block adjacent to a top side of the current block. One or more most probable modes (MPMs) can be derived from the neighboring coding modes and the BL coding mode, and the MPMs is then used for predictive coding of the current Intra mode.

    Abstract: A method for identifying an actual view order of image frames of a stereo image pair includes at least the following steps: receiving the image frames; obtaining image characteristics by analyzing the image frames according to an assumed view order; and identifying the actual view order by checking the image characteristics. In addition, a machine readable medium storing a program code is provided. The program causes a processor to perform at least the following steps for identifying an actual view order of image frames of a stereo image pair when executed by the processor: receiving the image frames; obtaining image characteristics by analyzing the image frames according to an assumed view order; and identifying the actual view order by checking the image characteristics.
