Problems solved by technology

[0004] In related technologies, in the video decoding process, in order to ensure the output target frame rate of the system, a higher voltage and frequency are often set when the decoder starts decoding, but it is likely not necessary to set it in the actual decoding process The relatively high voltage and frequency, which often leads to waste of system power consumption

Abstract

The invention provides a method and a device for video decoding. The method comprises the following steps of obtaining the voltage and frequency of the current decoding; calculating the unit time of the current decoding; according to the unit time of the current decoding and the preset time threshold value, judging whether the voltage and frequency of the current decoding need to be adjusted or not, wherein if the voltage and frequency of the current decoding need to be adjusted, the voltage and frequency of the current decoding are adjusted; and decoding an original code stream according to the adjusted decoding voltage and frequency. The method and the device have the advantage that the system power consumption in the decoding process is saved.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer and multimedia technologies, and in particular, to a video decoding method and a video decoding device. Background technique [0002] Decoding is the process of restoring the original code stream to the content it represents in a specific way, or converting electrical pulse signals, optical signals, radio waves, etc. into the information, data, etc. it represents. [0003] With the continuous development of computer science technology and multimedia, decoding technology has been widely used in various aspects of daily life, for example, in DVD, in VCD, in the video transmission process of various satellite and terrestrial TV broadcasting systems. [0004] In related technologies, in the video decoding process, in order to ensure the output target frame rate of the system, a higher voltage and frequency are often set when the decoder starts decoding, but it is likely not necessary ...
