Abstract: The present disclosure provides a color compensation circuit, a display apparatus, and a color compensation method, wherein the color compensation circuit comprises an acquisition unit for acquiring, from a video signal, gray image of a frame to be displayed and chrominance image of any color; wherein a chrominance value in the video signal, corresponding to at least a portion of pixels within the chrominance image, is absent; a processing unit for smoothly processing the chrominance value in the chrominance image according to the change trend of gray value in the gray image to obtain a chrominance image with color compensated. The present disclosure can solve the problem that compression and decompression of a video signal during transmission will significantly decrease the frame display effect, and thereby helping improve the frame display effect in a transmission scenario with the loss of chrominance value of the video signal.

Abstract: A television volume control method and system are provided. According to the television volume control method, a television performs a process of a mutely turn-on mode after receiving a turn-on instruction, the process of the mutely turn-on mode comprising: acquiring a system time and determining whether the system time is within a preset rest time period or not; and the television being turned on mutely if it is determined to be within the preset rest time period, and being turned on normally if it is determined to be not within the preset rest time period. The problem of disturbing others due to a sound with a large volume being output suddenly when the TV is turned on is solved.
