1. An AV decoding device for decoding an AV data, said device comprising:
- an decapsulator unit for decapsulating a first section data of said AV data to output a first video data;
a video buffer unit, coupled to said decapsulator unit, for storing said first video data;
a picture split unit, coupled to said video buffer unit, for providing a picture information of said first video data in a picture; and
a video decoding unit, coupled to said video buffer unit and said picture split unit, for decoding a first picture data of said first video data, based on said picture information, to generate a first picture.

Abstract
A device for decoding AV data is provided. The device includes a plurality of sub-buffers to store video data, audio data and subtitle data, so that a data-decoding procedure can be efficiently performed. Besides, a method for providing each picture'"'"'s information in video data is disclosed. According to the compression standard of the AV data, the method applies a corresponding procedure to provide each picture'"'"'s information in video data. The picture information is useful to help a decoding unit to correctly decode the video data, so as to generate pictures.
