Abstract: Example video signal processing methods and apparatus are described. One example method includes performing chrominance compensation on a to-be-processed video signal based on a saturation adjustment factor corresponding to an initial luminance value of the to-be-processed video signal. As such, a color that is of the video signal obtained after chrominance compensation and that is perceived by human eyes is closer to a color of the video signal obtained before luminance mapping.

Abstract: The present application relates to an indication method for transmitting a physical control channel. The method includes: determining, by a radio node, one of space frequency block coding SFBC transmission and single frequency transmission, as a receiving mode used by user equipment to receive a downlink physical control channel; and sending, by the radio node, an indication message to the user equipment, where the indication message is used to instruct the user equipment to receive, in the receiving mode, the downlink physical control channel sent by the radio node. The user equipment receives the downlink physical control channel according to the receiving mode, thereby improving system performance.
