    摘要： The MPEG-4 Multiview Video Coding (MVC) standard provides the coding tools to compress images from more than one view. Traditionally, the base view of the multiple view images has to be coded by the MPEG-4 Advance Video Coding (AVC) standard. However, in some deployments, for compatibility to legacy players, MPEG-2 Video standard has to be used for the coding of the based view. This invention provides methods and apparatuses to compute the parameters required by the MVC encoder and decoder without signalling such information in the base view that is coded by the MPEG-2 video standard.

    摘要： The present invention provides a video coding method and a video decoding method which allow enhancement of coding efficiency and improvement in video quality. A video coding apparatus includes: a mode determination unit which determines a notification method for notifying a transform block size to be used in orthogonal transform of a current block to be either the implicit mode or the explicit mode, and outputs the ABT mode indicating the determined notification method; an orthogonal transformation unit which transforms the difference values between the input image and predicted image into frequency coefficients based on the transform block size determined in accordance with the determined notification method; a quantization unit which quantizes the frequency coefficients and output the quantized values; and a variable length coding unit which performs variable length coding on the quantized values, the ABT mode, and the like, so as to output a coded stream.

    摘要： A decoding method according to the present invention is a method of decoding a variable length code to a Run symbol and a Level symbol. The Run symbol indicates the number of consecutive coefficients each having a value of zero. The Level symbol indicates a value of a non-zero coefficient following the Run symbol. The decoding method includes decoding a variable length code to a code number, determining whether the code number obtained in the decoding belongs to a first range or a predetermined range, decoding the code number to a Run symbol and a Level symbol by referring to a table, when it is determined that the code number belongs to the first range, and decoding the code number to a Level symbol and then decoding a variable length code following the decoded variable length code to a Run symbol, without referring to the table, when it is determined that the code number belongs to the predetermined range.
