Abstract
1. Способ декодирования сигнала видео, содержащий этапы: ! проверка схемы кодирования сигнала видео; ! получение информации конфигурации для сигнала видео согласно схеме кодирования; ! распознавание общего количества кадров, использующих информацию конфигурации; ! распознавание межкадровой опорной информации на основании общего количества кадров; и ! декодирование сигнала видео на основании межкадровой опорной информации, причем информация конфигурации включает в себя по меньшей мере информацию кадра для идентификации кадра сигнала видео. ! 2. Способ по п.1, дополнительно содержащий этап проверки уровня для масштабируемости кадра сигнала видео, при этом сигнал видео декодируют на основании уровня. ! 3. Способ по п.1, в котором информация конфигурации также включает в себя временный уровень, флаг группы межкадровых изображений, и флаг IDR. ! 4. Способ по п.2, в котором на этапе декодирования, если сигнал видео соответствует основному кадру согласно уровню, декодируют сигнал видео основного кадра. ! 5. Способ по п.1, дополнительно содержащий этап получения информации для изображения в кадре, отличном от такового текущего изображения, используя информацию кадра, причем информация для изображения в отличном кадре используется при декодировании сигнала видео. ! 6. Способ по п.5, в котором этап декодирования сигнала видео дополнительно содержит этап выполнения компенсации движения, используя информацию для изображения в отличном кадре, при этом информация для изображения в отличном кадре включает в себя информацию вектора движения, и информацию опорного изображения. ! 7. Способ по п.5, в котором этап декодирования сиг� 1. A method for decoding a video signal, comprising the steps of:! checking the encoding scheme of the video signal; ! obtaining configuration information for a video signal according to a coding scheme; ! recognition of the total number of frames using configuration information; ! recognition of inter-frame reference information based on the total number of frames; and! decoding a video signal based on inter-frame reference information, wherein the configuration information includes at least frame information for identifying a frame of the video signal. ! 2. The method according to claim 1, further comprising the step of checking the level for scalability of the frame of the video signal, wherein the video signal is decoded based on the level. ! 3. The method of claim 1, wherein the configuration information also includes a time level, a frame group flag, and an IDR flag. ! 4. The method according to claim 2, in which at the decoding stage, if the video signal corresponds to the main frame according to the level, decode the video signal of the main frame. ! 5. The method according to claim 1, further comprising the step of obtaining information for an image in a frame different from that of the current image using frame information, the information for the image in an excellent frame being used when decoding a video signal. ! 6. The method according to claim 5, in which the step of decoding the video signal further comprises the step of performing motion compensation using information for the image in the excellent frame, wherein the information for the image in the excellent frame includes motion vector information and reference image information. ! 7. The method according to claim 5, in which the step of decoding sig
