Embodiment Construction

[0056] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0057] An embodiment of the present invention provides a method for controlling an FPGA when a laser TV video signal transmission fails, and the method can be implemented by a laser TV. Among them, laser TV can include components such as memory, FPGA, FRC, SOC, display part (DLP), main controller of FPGA, etc. The internal structure diagram of the device can be as follows figure 1shown. The FPGA includes a receiving end, a sending end, and a signal processing module. The receiving end can also be called an Rx (Receiver, receiving) module, and the sending end can also be called a Tx (Transmitter, sending) module. The receiving end and the sending end form a video signal transmission link. The main controller can be used to control the...

Abstract

The invention discloses a method and device for controlling an FPGA in the case of laser TV video signal transmission failure, belonging to the technical field of video signal processing. The method includes the following steps: resetting a receiving end when the failure is that a signal locking state of the receiving end is abnormal or the timing information obtained by analyzing a video signal through the receiving end has an error; and when the failure is that a signal locking state of a transmitting end is abnormal, resetting the transmitting end. By adopting the scheme of the invention, the phenomenon that a laser TV continuously maintains a display error state can be prevented.

Description

[0001] This application is a divisional application of the Chinese invention patent application 201710102703.9 filed on February 24, 2017 with the title of "Method and device for controlling FPGA when laser TV video signal transmission fails". technical field [0002] The invention relates to the technical field of video signal processing, in particular to a method and device for controlling an FPGA when a laser TV video signal transmission fails. Background technique [0003] With the development of technology, laser TV has been widely promoted. In order to meet the requirements of video data transmission speed, the current laser TVs all use VBO (V-By-One, a video signal transmission standard) signal. [0004] During the display process of the laser TV, the VBO signal will pass through SOC (System-On-Chip, system on chip), FRC (Frame Rate Conversion, frame rate converter), FPGA (Field-Programmable Gate Array, field programmable gate array ), DLP (Digital Light Processing, ...
