VBO signal processing method, FPGA and laser television

Abstract

The embodiment of the invention provides a VBO signal processing method, an FPGA and a laser television. The method comprises the steps of converting each VBO signal into a parallel signal, and recovering a clock signal from each parallel signal; caching the plurality of parallel signals; and reading all the cached parallel signal based on a target clock signal, wherein the target clock signal is one clock signal in the multiple clock signals recovered from the plurality of parallel signals. According to the method and the FPGA provided by the embodiment of the invention, transmission accuracy of the VBO signal between an SOC and the FPGA can be improved, and stability of a hardware system in the laser television can be enhanced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of laser televisions, in particular to a VBO signal processing method, FPGA and laser televisions. Background technique [0002] With the development of display technology, 4K TV or Ultra HD TV has become very common. There are many types of 4K TVs, among which 4K laser TV is a more common 4K TV. [0003] The existing 4K laser TV is mainly realized by the hardware system of "System on Chip (SOC) + Field Programmable Gate Array (FPGA) + laser source". The SOC and the FPGA are connected by a digital interface standard (V-by-One, referred to as VBO) signal specially developed for image transmission. In the FPGA, one VBO signal is converted into multiple parallel signals, and each parallel signal is independently Transmission, due to the problem of transmission delay between parallel signals, the final VBO signal obtained by the FPGA side is inaccurate, resulting in poor system stability,...

Problems solved by technology

Among them, SOC and FPGA are connected by digital interface standard (V-by-One, referred to as VBO) signal specially developed for image transmission. In FPGA, one VBO signal is converted into multiple parallel signals, and each parallel signal is independently Transmission, due to the problem of transmission delay between parallel signals, this will lead to inaccurate VBO signals finally obtained on the FPGA side, resulting in poor system stability, and display problems such as blurred screens and black screens are prone to occur
