P2P signal acquisition and conversion method and system and P2P signal acquisition and conversion board

Abstract

The embodiment of the invention discloses a P2P signal acquisition and conversion method and system and a P2P signal acquisition and conversion board, and relates to the technical field of display equipment, and the method comprises the steps: controlling SerDes to enter an oversampling receiving mode at a first preset working rate; acquiring an input P2P signal, and acquiring a clock training code signal corresponding to the P2P signal; determining the transmission rate of the P2P signal according to the clock training code signal; controlling the SerDes to enter an oversampling receiving mode at a second preset working rate; acquiring an oversampling data signal corresponding to the P2P signal at a second preset working rate; tracking the rate change of the oversampling data signal at the second preset working rate; and converting the oversampling data signal at the second preset working rate into an output signal consistent with the transmission rate. By implementing the method, the transmission rate of the P2P signal can be obtained, the P2P signal can be acquired, converted and restored, and the problem of P2P signal detection commonly existing in a TV complete machine factory is solved.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a P2P signal acquisition and conversion method, system and P2P signal acquisition and conversion board. Background technique [0002] In the field of display devices, different glass manufacturers adopt their own unique P2P protocols, which leads to the emergence of a wide variety of display device interfaces on the market. Usually, in order to ensure the versatility of the TV motherboard SOC, the motherboard SOC outputs a standard V- by-One signal, and the tcon board converts the standard V-by-One signal into P2P format signals corresponding to different display devices. The chip function of the motherboard SOC can now also be configured through software to realize some types of P2P signal output, which can be directly connected to the display device. The TV equipment manufacturer will consider the signal output scheme selected for different series of TVs as appr...
