Background
V-By-One, VBO for short, is a digital interface standard technology oriented to image information transmission. The technology can support 4.0Gbps high-speed signal transmission at most, and the special coding mode avoids the time lag problem between the data and the clock of the receiving end, so the VBO technology is widely applied to the field of ultra-high definition liquid crystal televisions, and the ultra-thin and ultra-narrow televisions are possible. In the VBO signal transmission, after handshaking between a Tcon board (Timing Controller) and a main board is successful, a display communication sequence is entered to transmit the VBO signal. The VBO signal includes a timing control signal embedded in the data signal in addition to the data signal. However, for VBO signal transmission performed in display communication after successful handshake, the timing control signal may be stochastically unstable, that is, the timing control signal in the VBO signal is unstable or exceeds the setting of the Tcon board, so that the Tcon board directly parses the data signal and the timing control signal from the VBO signal, and when displaying, the timing control signal embedded in the VBO signal is abnormal, the Tcon board cannot correctly parse image data from the received VBO signal, and meanwhile, there is no mechanism to feed back to the main board to adjust the timing control signal or retransmit the timing control signal, thereby causing abnormality in screen display.
However, a VBO interface is used to output the display data of the SOC chip to the TCON circuit board, and the VBO interface requires a large number of lines for transmitting data. Therefore, the conventional television architecture has complex interfaces and a large number of connecting lines of signal transmission interfaces, so that a large number of interface connectors around the system are caused, a large number of signal connecting lines cause a large requirement on the number of pins of the SOC or TCON chip, and a large number of connectors and chip pins increase the cost.
