Abstract
This application discloses a data transmission method and apparatus, and relates to the field of media technologies. The method includes: obtaining video data of a to-be-transmitted video; splitting first line video data in the video data into a plurality of video data packets; and transmitting the plurality of video data packets and at least one auxiliary data packet in a first line active area.
Claims20
A data transmission method, wherein the method comprises:
- obtaining video data of a to-be-transmitted video, wherein the video data is data of an image frame of the to-be-transmitted video;
- splitting first line video data in the video data into a plurality of video data packets, wherein the first line video data is a piece of line video data in the video data;
- and
- transmitting the plurality of video data packets and at least one auxiliary data packet in a first line active area, wherein the first line active area is a line active area corresponding to the first line video data, and the auxiliary data packet comprises data other than the video data of the to-be-transmitted video, wherein each of the plurality of video data packets comprises a first type identifier, and the first type identifier indicates that a type of data in the respective video data packet is video data, wherein the auxiliary data packet comprises a second type identifier, and the second type identifier indicates that a type of data in the auxiliary data packet is auxiliary data.
