    • In an implementation, a supplemental sequence parameter set (“SPS”) structure is provided that has its own network abstraction layer (“NAL”) unit type and allows transmission of layer-dependent parameters for non-base layers in an SVC environment. The supplemental SPS structure also may be used for view information in an MVC environment. In a general aspect, a structure is provided that includes (1) information (1410) from an SPS NAL unit, the information describing a parameter for use in decoding a first-layer encoding of a sequence of images, and (2) information (1420) from a supplemental SPS NAL unit having a different structure than the SPS NAL unit, and the information from the supplemental SPS NAL unit describing a parameter for use in decoding a second-layer encoding of the sequence of images. Associated methods and apparatuses are provided on the encoder and decoder sides, as well as for the signal.

    • The present principles relate to a hypothetical reference decoder (HRD) for a Scalable Video Coding extension for a compression algorithm. One such implementation proposes to modify the H.264/AVC HRD for use with the SVC of AVC. That implementation defines HRD constraints for each interoperability point of SVC. One implementation in particular is described, but other implementations are possible and are contemplated by the present principles. The changes for spatial, temporal, and SNR scalability are shown. There are also changes to the related HRD parameters followed that are shown. The several mentioned implementations provide rules for an HRD for SVC. At least one implementation proposes the SVC-HRD rules as modifications to the AVC-HRD rules. A user may use the proposed SVC-HRD rules to build an SVC-HRD and test a bitstream for SVC compliance.

    • The invention relates to a method of encoding an image divided into non-overlapping macroblocks themselves divided into non-overlapping blocks of N by N pixels into a binary stream. It comprises the steps of: —transforming each of the block into a transformed block of coefficients comprising one low frequency coefficient and N2-1 coefficients, called high frequency coefficients, of higher frequencies than the low frequency; —quantizing each coefficient of each of the transformed blocks with a quantizing parameter; —encoding the quantized coefficients into a binary stream. According to the invention, the low frequency coefficients of the transformed blocks are quantized with a same quantizing parameter, called first quantizing parameter.
