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.

A first selection circuit switches from first image data to switching image data in a vertical blanking period of the first image data. An output circuit outputs output image data at a frame rate different from that of second image data in a switching period in which the switching image data is selected by the first selection circuit. The first selection circuit switches from the switching image data to the second image data in an overlap period between a vertical blanking period of the switching image data and a vertical blanking period of the second image data.

A device includes memory configured to store image frame data of an image frame. The device also includes one or more processors configured to initiate a timer based on receiving a frame start indication of the image frame, the timer configured to expire after an expected receipt time of a frame end indication. The one or more processors are also configured to receive, via a communication link, the image frame data subsequent to receiving the frame start indication. The one or more processors are further configured to, responsive to expiration of the timer, initiate a reset operation corresponding to an error in receipt of the frame end indication.
