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 image coding method is used to code images to generate a coded stream. The image coding method includes: writing, into a sequence parameter set in the coded stream to be generated, a first parameter representing a first bit-depth that is a bit-depth of a reconstructed sample in the images; and writing, into the sequence parameter set, a second parameter which is different from the first parameter and represents a second bit-depth that is a bit-depth of an Intra Pulse Code Modulation (IPCM) sample in the images.

摘要： A coding method includes: defining an access unit; and coding each of the pictures included in the access unit, for each access unit. The defining includes: determining a unit of coding for determining whether the pictures included in the access unit are to be uniformly coded on a per-field basis or on a per-frame basis; and determining a field type for determining whether the pictures are to be uniformly coded as top fields or bottom fields when it is determined that the pictures included in the access unit are to be coded on a per-field basis. In the coding, each of the pictures is coded for each access unit in a format determined in the determining of a unit of coding and in the determining of a field type.

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.
