However, due to user habits, it is not feasible to modify the brightness of the LCD backlight
When the DDR frequency drops a lot, the playback effect of many high-bit-rate and high-resolution videos will deteriorate, but if the DDR frequency drops very little, it will not meet the requirements for truly reducing power consumption.

The invention provides a video playing control device and method. The video playing control device comprises a video playing control unit, a video playing state monitoring unit, a video source information obtaining unit, an SDRAM frequency modulation information providing unit, an SDRAM frequency modulation strategy unit and an SDRAM frequency modulation implementation unit. The SDRAM frequency modulation strategy unit determines a frequency modulation strategy according to playing state information determined by the video playing state monitoring unit, video source information obtained by the video source information obtaining unit and the information, that the device can conduct SDRAM frequency modulation, provided by the SDRAM frequency modulation information providing unit, and the SDRAM frequency modulation implementation unit executes the frequency modulation strategy to modulate frequency. The invention further discloses the video playing control method. By the adoption of the video playing control device and method, the frequency modulation strategy is determined and executed according to the relevant information of current playing video. Compared with the prior art, the device and method save the power consumption in the SDRAM underclocking period, effectively save power consumption and solve the problem of desynchrony of audio playing and video playing.
Description
technical field [0001] The present invention relates to the technical field of video playback processing, in particular to a video playback control device and method capable of reducing power consumption. Background technique [0002] With the popularization of mobile Internet devices, more and more users will use user terminal devices to browse the video inside the device or online video, so the battery life of the device's video playback becomes an intuitive indicator for users to evaluate the terminal device. The battery life of the device and its video playback depends entirely on the battery capacity of the device on the basis of the same hardware power consumption. However, devices of the same or similar size will not have batteries with very different capacities. Therefore, currently commonly used solutions include adjusting the brightness of the LCD backlight and fixedly reducing the frequency of DDR (Double Data Rate, double-rate synchronous dynamic random access m...
