Embodiment Construction

[0012] The present invention is achieved through the following measures, illustrated with an LED LCD TV: first , the previous single transmission method such as figure 1 As shown, the AV signal of the DVD player outputs the signal to the transmitting part, and then the receiving part outputs the AV signal to the LCD TV for display. The present invention scheme is figure 2 As shown in the system block diagram, the audio image processing chip MST6M48 (Star Semiconductor) and the transmitting module are composed of the transmitting part, and the receiving part is composed of the receiving module and the LCD screen. Since the MST6M48 chip can handle various types of input interfaces, such as AV, TV, USB, YPbPr, PC, HDMI, network and other interfaces, it can realize various types of signal wireless transmission.

[0013] secondly ,Such as image 3 As shown in the system launching part, the audio and image processing chip MST6M48 outputs LVDS differential signals (supplied to...

Abstract

The invention discloses a device for solving multiple audio / video wireless transmission and receiving, wherein a circuit for converting LVDS signals into TTL signals and a wireless emitting module are added, the image audio / video processing circuits of multiple audio / video devices are connected with the circuit for converting LVDS signals into TTL signals and the wireless emitting module; a television receiver is also correspondingly provided with a wireless receiving module matched with the wireless emitting module for displaying. The TTL signals are modulated in the wireless emitting module for emitting out; the design mainly aims at family cinemas, flat televisions, high-definition projectors, blue-ray players and other high-definition equipment can be connected with the device for solving multiple audio / video wireless transmission and receiving, wireless high-definition transmission can be achieved, and complex connection of signal wires can be avoided. The wireless transmission function can be added in products by video operators.

Description

technical field [0001] The present invention relates to a device and method for wireless transmission and reception of various audio and video, in particular to a technical solution for wireless transmission and reception using image signal decoding to output differential signal LVDS signals, thereby solving the problem of various signal sources (AV, PC, Y Pb Pr, HDMI, USB and other interfaces) can only compress and encode a single signal source, and have the defect of one-way transmission. Background technique [0002] As high-definition enters the home theater and becomes popular in modern families, people pay more and more attention to the beautiful layout of the home theater. The connection lines between TV, DVD player, projector, and stereo are often complicated and cumbersome, and are incompatible with the decoration of the room, especially the placement of the speakers in the home theater, and the connection between it and the host is even more difficult to handle. O...
