摘要:
The present invention relates to a video signal transmission device and the like that can support a variety of system specifications. The device includes a packer unit, an encoder unit, and a serializer. The packer unit generates, from a video signal of one or more pixels, a plurality of block signals having a packet configuration of size corresponding to the number of pixels and the number of tone bits of a color signal constituting a video signal. At this time, a control signal including a pulse having a width corresponding to the number of pixels and the number of tone bits is also generated. The encoder unit applies encoding processing having encoding efficiencies that are different between a first period and a second period of a control signal that are distinguished depending on existence or non-existence of a pulse to the block signals.

Provided are a transmitter apparatus, a receiver apparatus and a communication system wherein a simple structure is used to positively confirm a bit rate as changed. In a communication system (1), a transmitter apparatus (2) changes the bit rate of a serial data signal (S data ) such that the bit rate of the serial data signal (S data ) exhibits a fixed value for a period that is a fixed times of a clock cycle. The transmitter apparatus (2) then transmits the serial data signal (S data ) to a receiver apparatus (3). In the receiver apparatus (3) having received the serial data signal (S data ), it is determined whether the bit rate of the serial data signal (S data ) exhibits the fixed value for the period that is a fixed times of the clock cycle. If so determined, the receiver apparatus (3) receives a training data (T data ) from the transmitter apparatus (2) and then enters a process of confirming the bit rate as changed.

A transmission/reception system 1 includes a transmission device 10 configured to transmit image data and a reception device 20 configured to receive the image data transmitted from the transmission device 10. The transmission device 10 includes a serializer 11, an encoding unit 12, a data buffering unit 13, a data selection unit 14, a counter 15, and a synchronization signal generation unit 16. The data buffering unit 13 buffers data every n bits in synchronization with the clock. The data selection unit 14 outputs m-bit data selected from the data buffered by the data buffering unit 13 on the basis of a count value from the counter 15.

Provided are a transmission device, a receiving device, and a communication system having a simple configuration and capable of reliably executing the confirmation of a changed bit rate. The communication system 1 sends, to the receiving device 3, a serial data signal S data that is set as a constant value across a period of a constant multiple of a cycle of the clock when a bit rate of a serial data signal S data in the transmission device 2 is changed. The receiving device 3 that received the serial data signal S data receives training data T data from the transmission device 2 when it is determined that the serial data signal S data is a constant value across a period of a constant multiple of a cycle of the clock, and proceeds to the processing of confirming the changed bit rate.
