Abstract: The presented invention enables the reception of video signals with variable channel synchronization. All logic elements are located on the receiver side that can work with any transmitter. The receiver comprises one or more sets of modules for image processing. These sets of modules adapt the speed of sending data to the frame generator to the speed of data creation on the transmitter side without the use of a precise time pulse source on both sides of the transfer and without feedback from the receiver to the transmitter. The receiver further includes a memory of channel synchronization configuration which determines the allocation of synchronized channels to groups and the detector of starts of frames. These, along with multiplexers of clock signals, ensure the synchronization of channels within groups and allows for modifying this channel distribution.

Abstract: A clock transfer circuit receives input data synchronized with a first clock, and outputs, as output data, data synchronized with a second clock having a frequency different from that of the first clock. A write address controller is operating according to the first clock, and provides a write address to a memory. A read address controller is operating according to the second clock, and provides a read address to the memory. A cycle comparator compares the cycle of a predetermined event between the input data and the output data. Based on such a comparison result, the clock adjuster adjusts the frequency of the second clock.

The generated output color values correspond to colors perceived by the human visual system for the same image as that captured by the image capture device. Image capture device gamut is also determined.
