Low power consumption encoding method and device

Abstract

Embodiments of the present invention provide a low-power encoding method and device. The method includes: receiving the number of skip macroblocks corresponding to the target frame sent by the target encoder and the number of macroblocks whose motion vector MV is a preset value; according to the number of skip macroblocks and the number of macroblocks whose motion vector MV is a preset value The number of encoding complexity index is obtained, and the scene type corresponding to the target frame is judged; if the number of the first predetermined scene in the scene type corresponding to multiple target frames is greater than the threshold value, the slave encoder is used as the target encoding encoder to start encoding from the encoder. In the embodiment of the present invention, by using the slave encoder as the target encoder, the slave encoder encodes the subsequent target frame. Since the power consumed by the slave encoder is smaller than that of the master encoder, the slave encoder replaces the master encoder for The target frame corresponding to the simple motion scene is encoded, which effectively reduces the encoding power consumption compared with the method in which all target frames are encoded by the main encoder.

Description

Technical field [0001] The embodiments of the present invention relate to communication technology, and in particular to a low-power encoding method and device. Background technique [0002] Compared with the H.264 video protocol, the coding complexity of the latest H.265 video protocol is increased by 8-10 times, resulting in a linear increase in the power consumption of the H.265 encoder. [0003] The prior art uses a gated clock to solve the problem of high power consumption of the H.265 encoder. Among them, the gated clock is specifically divided into frame-level gated clock and module-level gated clock. The frame-level gated clock refers to the encoder turning on all internal clocks during the encoding process. This all clock includes the register configuration clock, which is turned off after encoding. All clocks except for the register configuration clock to reduce power consumption; the module-level gated clock refers to the internal sub-module of the encoder when encoding...

AI Technical Summary

Problems solved by technology

[0004] Since the gating clock can only save the power consumption of the encoder in the encoding gap, if the encoder is encoding in the full-speed operation mode, the encoding gap of the encoder is small, and the power consumption saved by using the gating clock is limited
