Circuitry for providing an output video signal from a portable device to an external display, the circuitry including a processor block with an image processor, and a video encoder block with a video encoder for providing the output video signal to the external display, the processor block and the video encoder block being connected to each other by a serial interface arranged to provide image date from the processor block to the video encoder, the serial interface having at least one data lane and at least one first clock lane, wherein the video encoder block includes a first input connected to the at least one data lane for receiving image data and a second input connected to the at least one first clock lane for receiving a first clock signal, and wherein at least one of the video encoder block and the processor block has a third input arranged to receive a control signal for controlling data flow over the serial interface.
Circuitry for providing an output video signal from a portable device to an external display, the circuitry comprising a processor block comprising an image processor, and a video encoder block comprising a video encoder for providing said output video signal to said external display, said processor block and said video encoder block being connected to each other by a serial interface arranged to provide image data from said processor block to said video encoder, said serial interface comprising at least one data lane and at least one first clock lane, wherein said video encoder block comprises a first input connected to said at least one data lane for receiving image data and a second input connected to said at least one first clock lane for receiving a first clock signal, and wherein said processor block comprises a third input arranged to receive a control signal indicating when said video encoder is ready to receive image data from the processing block via said serial interface.
A method of transmitting image data from a processor block to a video encoder block of a portable device, said video encoder block comprising a video encoder arranged to output a video signal to an external display, said method comprising:
