TRANSMISSION CONTROL SYSTEM OF MULTI-MEDIA SIGNAL, TRANSMITTER CONTROL CIRCUIT AND RECEIVER CONTROL CIRCUIT

摘要

A multimedia signal transmission control system is provided, which includes a transmitter control circuit and a receiver control circuit coupled with each other. The transmitter control circuit packs a control signal and at least one of multimedia signals into first hybrid data packets in an active video period of a video frame, and packs the control signal and another at least one of the multimedia signals into second hybrid data packets in a vertical front porch and a vertical back porch of the video frame. The receiver control circuit receives the first hybrid data packets in the active video period, and receives the second hybrid data packets in the vertical front porch and the vertical back porch. The receiver control circuit unpacks the first hybrid data packets and the second hybrid data packets to provide the control signal and the multimedia signals to a display module.
