The present disclosure relates to systems and methods for transmitting data in a video signal. The systems may perform the methods to generate a data frame, wherein the data frame may include at least a frame header and frame data, the frame header may include at least one autocorrelation and cross-correlation sequence; insert the data frame into an area of a video signal, wherein the inserted area of the video signal is not an area of line and field synchronization or an area of effective video; transmit the video signal having the data frame to another device.

Methods, systems, and media for transmitting data in a video signal

A method relating to image compression includes acquiring image data of an image, wherein the image includes a matrix of pixels, and the image data include pixel values of the matrix of pixels. The method also includes generating, based on the image data, a first-level data set including pixel values of a portion of the matrix of pixels. The method further includes determining at least one coding mode for the first-level data set, encoding the first-level data set into a code stream based on the at least one coding mode, and packaging the code stream into a modified code stream.
