Abstract: Methods and devices for video encoding are provided. In the method, the device divides a current picture into one or more coding units; determines, for a current luma transform block in a current coding unit of the one or more coding units, whether a first variable indicating an intra subpartition (ISP) split type equals ISP_NO_SPLIT. In response to determining the first variable equals ISP_NO_SPLIT, the device determines a luma block flag context index for a luma block flag of the current luma transform block as being equal to zero or one without determining whether the current luma transform block is smaller than the current coding unit. In response to determining the first variable does not equal ISP_NO_SPLIT, the device determines the luma block flag context index based on a second variable of a previous luma transform unit in the current coding unit.

Abstract: A method for reading and writing frame images with multiple buffer blocks and a system are provided. In the system, when an input-fast mode is switched to an input-low mode, a read end decides whether to read a next buffer block according to a writing progress. If a write end does not change the buffer block to be written, the read end keeps reading the buffer block, and otherwise the read end selects a next buffer block to be read. In an instance that the read end is required to read the same frame image repeatedly, when the input-slow mode is switched to the input-fast mode, the write end decides whether to write a next buffer block according to a reading progress. The write end selects a next buffer block to be written with a next frame image if the read end already reads last buffer block.
