Abstract

Embodiments of the present disclosure provide a coefficient coding method, an encoder, a decoder, and a computer storage medium. The method includes the following. A bitstream is parsed to obtain a video flag. When the video flag indicates that a video satisfies a preset condition, the bitstream is parsed to obtain a last-significant-coefficient position-reverse flag and coordinate information of a last significant coefficient. When the last-significant-coefficient position-reverse flag indicates that a position of the last significant coefficient is reversed for a current block, the position of the last significant coefficient is determined by calculation with the coordinate information of the last significant coefficient. According to a preset scanning order, all coefficients before the position of the last significant coefficient are decoded to determine coefficients of the current block. As such, the throughput and coding speed of coefficient coding can be improved while improving compression efficiency in the video coding scenarios with high bit depth, high bitrate, high quality, or lossless compression.

A transform block of a frame of the video encoded with regular residual coding, the decoder infers sb coded flags for an inferred subblock of the transform block whose sb coded flag is not present to be 1 if the subblock is a DC subblock and/or the last subblock in the transform block containing a non-zero coefficient level. Otherwise, sb coded flag Is inferred to be 0. If the transform block is encoded with transform skip residual coding, sb coded flag for the subblock whose sb coded flag is not present is inferred to be 1. The decoder determines the initial context value for an entropy coding model based on the sub block flags of the inferred subblocks and determines the sub block flags of coded subblocks using the entropy coding model.

Abstract

In some embodiments, a video decoder decodes a video from a bitstream of the video. The video decoder extracts, from the bitstream of the video, an additional bit count M indicating a quantity of additional general constraints information (GCI) bits included in the bitstream of the video. The additional bits include flag bits indicating respective additional coding tools to be constrained for the video, and an expected value of the additional bit count is either 0 or 6. The decoder extracts M-6 bits that follow six flag bits in the bitstream in response to determining that the extracted additional bit count M is greater than 6. The decoder further decodes the remaining portion of the bitstream into images independent of the extracted M-6 bits and based, at least in part, upon constraints specified for the respective additional coding tools by the six flag bits.

Abstract

A medium access recovery method executed by a wireless mobile station (STA) is provided. When losing medium synchronization due to transmission by another mobile station affiliated with the same multi-link device (MLD), the mobile station starts a medium synchronization delay timer, such as MediumSyncDelay timer, at the end of the transmission by another mobile station. The method improves medium access recovery by at least determining whether to allow backoff in a delay time kept by the delay timer, whether to allow overlapping basic service set (OBSS) packet detection (PD) spatial reuse (SR), or whether to reset the delay timer with respect to a subsequent transmission event, or adjusting an energy detection (ED) threshold.

Abstract

Embodiments of the present disclosure provide a coefficient coding method, an encoder, a decoder, and a computer storage medium. The method includes the following. A bitstream is parsed to obtain a video flag. When the video flag indicates that a video satisfies a preset condition, the bitstream is parsed to obtain a last-significant-coefficient position-reverse flag and coordinate information of a last significant coefficient. When the last-significant-coefficient position-reverse flag indicates that a position of the last significant coefficient is reversed for a current block, the position of the last significant coefficient is determined by calculation with the coordinate information of the last significant coefficient. According to a preset scanning order, all coefficients before the position of the last significant coefficient are decoded to determine coefficients of the current block. As such, the throughput and coding speed of coefficient coding can be improved while improving compression efficiency in the video coding scenarios with high bit depth, high bitrate, high quality, or lossless compression.
