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.

In prior art documents, no consideration is given as to how to more faithfully preserve image (here and subsequently also termed video) data of larger size during transmission. Provided is an image transmission device for transmission of image data, characterized by having a compression processor for compressing image data, and an output section for outputting compressed data having been compressed by the compression processor, the output section outputting the compressed data separately during a first interval and a second interval different from the first interval.

A transmitting device for communicating via a multimedia communication link includes a compression circuitry that receives blanking period data corresponding to blanking states of video blanking periods. The compression circuitry compresses the blanking period data into compressed blanking period data. The transmitting device also includes an interface that transmits signals corresponding to the compressed blanking period data via one or more multimedia channels of the multimedia communication link.

There is provided with a communication apparatus. First video data comprising repetition of an effective interval in which frame image data of a first video is input, and an interval in which frame image data is not input, and communication data other than the video data are obtained. A method of multiplexation of the first video data and the communication data is set in accordance with whether or not in the effective interval of the first video data. Data multiplexed in accordance with the set method of multiplexation is transmitted.
