Problems solved by technology

[0003] Although WHDI has its unique advantages, it is also very complicated to use, and the technical threshold is also high. The wireless high-definition module launched by our company fills this gap, so that general manufacturers can easily and quickly launch products with WHDI with only this module. technical product

Embodiment Construction

[0015] 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.

[0016] 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.

[0017] Such as figure 1 , The transmitting part of the wireless high-definition video transmission module is mainly composed of baseband processing, radio frequency processing, power amplifier, control MCU and PF antenna. Digital video and audio data are input through the MIPCI_E interface and sent to the WHDI video analysis and baseband processing chip AMN2120. The audio and video data, control data, etc. are graded and encoded, and the dig...

Abstract

The invention discloses a wireless high-definition video transmission module which comprises an emitting part and a receiving part, wherein the emitting part comprises a baseband processor, a WHDI (Wireless Home Digital Interface) video analyzer, a power amplifier, a control MCU (Microprogrammed Control Unit) and a PF (Pulse Frequency) antenna; the receiving module receives effective audio and video and control data from an air interface through five paths of antennae, the effective audio and video and the control data are sent to a radio frequency chip AMN (Artificial Mains Network) 3210 and then demodulated into five paths of digital IQ (Intelligence Quotient) signals, and the five paths of digital IQ signals are decoded by a baseband chip ANM (Answer Message) 2220. The wireless high-definition video transmission module is integrated into an audio and video device so that a user can easily utilize a WHDI technology to realize wireless transmission of high-definition signals, has the advantages of small transmission delay (less than 1ms), high video definition (supporting 1080P), no compression, long transmission distance (more than 30m), capability of penetrating through barriers, and the like.

Description

technical field [0001] The invention relates to a wireless high-definition video transmission module. It is mainly integrated in audio and video equipment to realize seamless connection between various audio and video sources and display devices, and can be widely used in many fields such as home, office, and entertainment. Background technique [0002] Foreign products with this architecture use WirelessHD. The frequency used by WirelessHD is 60G, which is significantly inferior to products using WHDI in terms of distance and wall penetration; since 60GHz spectrum technology uses a large amount of bandwidth to process uncompressed high-definition video signals, its signal transmission has obvious Directionality, the corresponding hardware products generally need to operate the line of sight. [0003] Although WHDI has its unique advantages, it is also very complicated to use, and the technical threshold is also high. The wireless high-definition module launched by our com...
