Abstract: A method and an apparatus for processing a high dynamic range (HDR) video including a subtitle, where the method includes: encapsulating HDR video data into a video data frame that matches a transmission interface; encapsulating subtitle information into a subtitle information frame that matches the transmission interface; and separately transmitting the video data frame and the subtitle information frame to a display device through the transmission interface, where the video data frame and the subtitle information frame are packets in two types of formats. According to the method provided in this application, content and subtitle information of a dynamic metadata HDR video are separately transmitted to the display device. In this way, the display device can obtain the separated video content and subtitle information, and then separately perform corresponding processing on the HDR video and a subtitle.

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.

Abstract: In a data preparation process, raw data in a database is classified into first-type data and second-type data. In a data retrieval process, a first retrieval range is determined in the first-type data, and to-be-retrieved data is retrieved in the first retrieval range, to obtain a first retrieval result; the to-be-retrieved data is retrieved from all of the second-type data, to obtain a second retrieval result; and finally, a final retrieval result is determined from the first retrieval result and the second retrieval result.

Abstract: An image processing method determining a format of first image data, determining a first interface mode that is currently used, where the first interface mode is determined when the processing device establishes physical connections with a display device, and the format of the first image data format is not supported by the first interface mode, and processing, the first image data based on the first interface mode to generate second image data, where a format of the second image data is supported by the first interface mode. Image data will be processed when an image format of the image data is not supported by the first interface mode.
