AI Technical Summary

Problems solved by technology

Therefore, due to the lack of a bitstream start address for each block in the bitstream, existing decoding designs cannot directly decode a block in a multiblock picture without decoding the previous block in the same multiblock picture
Furthermore, existing decoding designs cannot decode multiple blocks in the same multi-block picture in parallel due to the lack of a bitstream start address for each block in the bitstream

Embodiment Construction

[0021] Certain terms are used throughout the specification and preceding claims to refer to particular elements. Those of ordinary skill in the art should understand that hardware manufacturers may use different terms to refer to the same element. The description and the preceding 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. The "comprising" mentioned throughout the specification and the preceding claims is an open-ended term, so it should be interpreted as "including but not limited to". Otherwise, the term "coupled" includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

Abstract

A block processing method at least includes the following steps: analyzing the bit stream of a multi-block picture, so as to obtain information related to the bit stream address from the segment header of a specific segment of the multi-block picture; using a block processing circuit to at least receive the bit stream address The associated information and at least reference to the received bitstream address associated information is used to determine the bitstream start address of a specific tile of the multi-tile picture.

Description

[0001] cross reference [0002] This application claims priority to U.S. Provisional Patent Application No. 61 / 750,413, filed January 9, 2013; priority is claimed to U.S. Patent Application No. 14 / 142,929, filed December 30, 2013 . These patent applications are hereby incorporated by reference in their entirety. technical field [0003] The present invention relates to processing multi-block pictures, in particular to a method for determining the bit-stream start address of a block of a multi-block picture with reference to bit stream address related information obtained from segments (e.g. slices) of a multi-block picture and device. Background technique [0004] As proposed by the High-Efficiency Video Coding (HEVC) specification, a picture can be divided into multiple tiles, and a tile can be divided into multiple slices. Within each slice, the largest coding units (LCUs) are raster-scanned. Within each square, slices are scanned sequentially. In each multi-tile pic...
