Embodiment Construction

[0016] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0017] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0018] like figure 1 , The 40PIN double-row socket is mainly used to interface with the TV decoder board LVDS signal, and its signal pin definition is shown in the attached figure. The LVDS receiving chip DTC30LM36 mainly converts the LVDS signal from the TV decoder board into a digital RGB signal; the 6PIN single-row socket is mainly used to interface with the IIS audio signal of the TV decoder board. The baseband chip AMN2120 classifies a...

Abstract

The invention discloses a wireless high-definition low voltage differential signaling (LVDS) video transmission module, which is mainly used for televisions and realizes wireless high-definition audio and video signal transmission of the televisions. The module comprises an LVDS receiving module, a base band processing chip, a wireless home digital interface (WHDI) radio frequency processing chip, a power amplifier, a television decoding board, a micro control unit (MCU) and a power factor (PF) antenna. The wireless high-definition LVDS video transmission module is integrated in the television decoding plate so that the television can perform wireless transmission of high-definition signals, and has the advantages of low transmission delay time (shorter than one microsecond), high video resolution (supporting 1080P), compression absence, far transmission distance (more than 30 meters), obstacle penetrability and the like; meanwhile, the whole television becomes lighter and thinner.

Description

technical field [0001] The invention relates to a wireless high-definition LVDS video transmission module, which is mainly used in a TV set to realize wireless high-definition audio and video signal transmission of the TV set. Background technique [0002] The product uses WHDI technology, which can transmit uncompressed video signals in 1080p format at 5GHz frequency throughout the home. In terms of data transmission rate, the transmission rate reaches 3Gbps when transmitting 1080p video signals with 40MHz bandwidth; the transmission rate is 1.5Gbps when transmitting 720p and 1080i video signals with 20MHz bandwidth. In addition, the product also supports the CEC protocol and High-bandwidth Digital Content Protection (HDCP) used in wireless HDMI. Because 5GHz signals can easily penetrate walls, the product can be used not just in a single room, but throughout your home. Existing TVs are still transmitted by cable, and the wiring is cumbersome. At the same time, because th...
