Embodiment Construction

[0017] Certain terms are used in the description and claims to refer to particular elements. Those skilled in the art should understand that a manufacturer may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Through the narration of the following examples and cooperate with the full text Figure 1 to Figure 3 To illustrate the present invention, but the devices, components, methods, and steps in the following description are used to explain the present invention, and should not be used to limit the present invention

[0018] According to the VP8 / WebP...

Abstract

The invention provides a video / image decoding system, which includes a buffering device for buffering a multi-segmented video / image bit stream. The multi-segmented video / image bitstream transmits multiple compressed frames, and each compressed frame has multiple segments. The video / image decoding system further includes a first bit stream buffer and a second bit stream buffer. The first bitstream buffer is used for buffering data of a first segment among the plurality of segments of a specific compressed frame. The second bitstream buffer is used for buffering data of a second segment among the plurality of segments of the specific compressed frame. The video / image decoding system of the present invention can improve the decoding efficiency of the decoder. In addition, the invention also provides a corresponding video / image decoding method.

Description

technical field [0001] The present invention relates to video / image processing, in particular to a video / image decoding system for buffering multi-partition video / image bitstream and its corresponding video / image decoding method. Background technique [0002] VP8 is a kind of An open video compression format published, like many current video compression schemes, VP8 is also based on deconstructing the frame (frame) into square sub-blocks containing pixels, using the previously reconstructed block to process these sub-blocks The blocks are predicted and a discrete cosine transform (DCT) is used to adjust for these predictions (and to synthesize unpredicted blocks). However, in special cases, VP8 will use the Walsh-Hadamard transform (Walsh-Hadamard transform, WHT), rather than the generally used discrete cosine transform. [0003] WebP is an image format developed by Google based on VP8. Furthermore, WebP is based on VP8's intra-frame coding (intra-frame coding) and adopt...
