Abstract:
1. A high-resolution still picture decoding device, comprising: a memory device having a bit-stream buffer, a temporary buffer and a frame buffer, the bit-stream buffer being adapted to store bit-stream data from a storage media; and a decoding means for decoding the bit-stream data in the bit-stream buffer and storing decoded frame data in the frame buffer or the temporary buffer, such that, when a still picture is to be displayed, the frame buffer stores a part of the frame data that has been decoded from a part of the bit-stream data and corresponds to the still picture, and the temporary buffer is provided to store the other frame data from the other part of the bit-stream data which has not been decoded and which is to be decoded in real time as the still picture is being displayed, and the decoded frame data in the frame buffer and the real-time decoded frame data from the temporary buffer are output for displaying a high-resolution still picture, wherein the frame data from the bit-stream buffer is represented by multiple macroblock lines after being decoded by the decoding means, the frame buffer only stores a portion of the macroblock line that has been decoded and corresponds to the frame data of the still picture, and the temporary buffer has a memory space for storing at least one macroblock line for decoding in real time as the still picture is being displayed, wherein the frame buffer stores only a half of the frame data that has been decoded and corresponds to the picture and the temporary buffer has a memory space less than that of the frame buffer.
