    摘要: Structured ASICs that are equivalent to FPGA logic designs are produced by making use of a library of known structured ASIC equivalents to FPGA logic functions. Such a library is expanded by a process that searches new FPGA logic designs for logic functions that either do not already have structured ASIC equivalents in the library or for which possibly improved structured ASIC equivalents can now be devised. The new and/or improved structured ASIC equivalents are added to the library, preferably with version information in the case of FPGA logic functions for which more than one structured ASIC equivalent is known.

    摘要: Disclosed is a method for enabling scalable progressive downloading of video signals. In the method, when a server transmits scalably encoded content data to a client, the server transmits some of the content data from a head of the content data to a tail of the content data according to transmission conditions, and transmits some of residual data of the content data having not been transmitted in the prior process. When scalably coded transmission content data is reproduced, the transmission content data are stored in a storage means as a file, the content data is read, decoded and output. Further, the recorded content data are read while an area having no recorded content data is skipped based on a specific code in the file.

    摘要: Disclosed is a method for scalably encoding and decoding a video signal. The video signal is encoded through an inter-layer prediction scheme based on a data stream of a base layer encoded with ×¼ resolution. The inter-layer prediction scheme applied between the enhanced layer and the base layer representing ×4 resolution difference includes a motion prediction scheme for predicting motion and dividing a macro block of the enhanced layer based on division information, mode information, and/or mode information of a block of the base layer. Thus, the inter-layer prediction scheme is applied between layers representing ×4 resolution difference, thereby improving a coding efficiency.

    摘要: A method and apparatus for encoding video signals using motion vectors of predictive image frames of an auxiliary layer and decoding such encoded video data is provided. Video signal is encoded in scalable MCTF scheme to output an enhanced layer (EL) bitstream and encoded in another specified scheme to output a base layer (BL) bitstream. During MCTF encoding, information allowing a derivative vector to be used as a motion vector of an image block in a frame in the video signal is recorded in the EL bitstream. The derivative vector is obtained by multiplying a motion vector of a block, temporally adjacent to the image block, in the BL bitstream by an EL-to-BL frame interval ratio and scaling the multiplied vector by an EL-to-BL frame size ratio. Using the correlation between motion vectors of temporally adjacent frames in different layers reduces the amount of coded motion vector data.

    摘要: A method for scalably encoding and decoding a video signal is provided. If a frame temporally coincident with a current frame in an enhanced layer including a target macroblock is not present (i.e., if there is a missing base layer frame) in a base layer when the target macroblock is predicted during encoding of the enhanced layer, the target macroblock is encoded in an intra mode using a past and/or future frame of the base layer prior to and subsequent to the current frame. Thus, inter-layer prediction can be applied even to a missing picture when a video signal is scalably encoded, thereby increasing coding efficiency.

    摘要: A method and apparatus for encoding video signals of a main layer using motion vectors of predictive image frames of an auxiliary layer and decoding such encoded video data is provided. In the encoding method, a video signal is encoded in a scalable MCTF scheme to output an enhanced layer (EL) bitstream and encoded in another specified scheme to output a base layer (BL) bitstream. During MCTF encoding, information regarding a motion vector of an image block in an arbitrary frame in a frame sequence of the video signal is recorded using a motion vector of a block, which is present, at a position corresponding to the image block, in an auxiliary frame present in the BL bitstream and temporally separated from the arbitrary frame. Using the correlation between motion vectors of temporally adjacent frames in different layers reduces the amount of coded motion vector data.
