    Publication number: 20130010862
    Abstract: An encoding apparatus and an encoding method, a decoding apparatus and a decoding method, a recording medium, and a program suitable for encoding image signals with a higher compression ratio for transmission or accumulation. In an arithmetic coding section, from among the syntax elements of input image compression information, the frame/field flag is first encoded by a frame/field flag context model. When the macroblock to be processed is subjected to frame-based encoding, a frame-based context model, specified in the current H.26L standard, is applied. On the other hand, when the macroblock to be processed is subjected to field-based encoding, a field-based context model is applied for the syntax elements described below.

  • Method and apparatus for coding image information, method and apparatus for decoding image information, method and apparatus for coding and decoding image information, and system of coding and transmitting image information
    Patent number: 8351501
    Abstract: An image decoding method is for decoding a bit stream in an image decoding apparatus. The method includes receiving the bit stream and a weight parameter that is added to a luma quantization parameter by an addition operation. The method also includes decoding, in a decoding unit in the image decoding apparatus, the bit stream and generating a chroma component of quantized coefficients. In addition, the method includes performing, in a dequantization unit in the image decoding apparatus, dequantization on the chroma component of quantized coefficients using the chroma quantization parameter calculated on the basis of a luma quantization parameter weighted by the weight parameter.

  • IMAGE PROCESSING DEVICE AND METHOD
    Publication number: 20120294358
    Abstract: An image processing device and method, enabling improvement in encoding efficiency. A plane approximation unit uses each of pixels values themselves of a block to be processed to obtain each of the parameters of a function representing a plane approximating the pixel values. A plane generating unit obtains pixel values on a plane represented by the supplied plane parameters. A prediction encoding unit predicts the values of the plane parameters, and obtains the difference between the prediction values and the actual plane parameter values, thereby reducing the data amount thereof. The entropy encoding unit further performs entropy encoding of the encoded plane parameters. The encoded plane parameters are supplied to the decoding side.

  • Encoding device and method, decoding device and method, edition device and method, recording medium, and program
    Patent number: 8315313
    Abstract: The present invention relates to an encoding device and a method, a decoding device and a method, an editing device and a method, a storage medium, and a program which can perform encoding and decoding so that buffer failure does not occur. Information, such as a minimum bit rate, a minimum buffer size, and a minimum initial delay time, is contained in a random access point header contained in an accessible point in a bitstream. A bitstream analyzing unit 72 analyzes an input bitstream, sets the above-mentioned information, and outputs the resulting information to a buffer-information adding unit 73. The buffer-information adding unit 73 adds the input information to the input bitstream and outputs the resulting bitstream. The present invention is applicable to an encoding device and a decoding device which process bitstreams.
