Xdi systems, devices, connectors and methods

Abstract

The invention provides systems, devices, connectors and methods to send compressed audio video serial digital signals thru local systems with significantly reduced bandwidth requirements and device costs, over longer cable runs and with higher system flexibility (i.e. connection topologies and scalability), with much simpler and installation friendly single coax cables and connectors, without introducing any signal quality losses or delays comparing to the current uncompressed digital systems like HDMI, DVI, DP or SDI when using the already compressed audio video content. The invention also provides solutions for integrating the uncompressed audio video content and Internet content into this system. These systems, devices, connectors and methods are collectively called XDI (Extended Digital Interface).

Description

[0001] Cross-references with related applications [0002] This application claims priority to US Provisional Patent No. 62 / 583,867, filed November 9, 2017, which is hereby incorporated by reference in its entirety. technical field [0003] This invention is about a new audio-video standard that uses compressed audio-video signals in serial format to transmit 4k, 8k (or higher resolution) video over very long distances over low-cost coaxial copper wires , and devices that use compressed audio-video signals at very low data rates, resulting in very low bandwidth requirements and therefore much lower cost and much higher reliability, and provide flexible system topologies (star or daisy chain or their the mix of). This new standard and corresponding electronic equipment and software will have exactly the same sound as existing uncompressed standards such as HDMI (High Definition Multimedia Interface), DVI (Digital Visual Interface), DP (Display Interface) and SDI (Serial Digita...

AI Technical Summary

Problems solved by technology

[0006] 2) High device bandwidth requirements and cost: At 64Gbps, the integrated circuits used to manufacture these devices can be very expensive, and printed circuit board layout design becomes very difficult

[0008] 3) System reliability and compatibility issues: the higher the signal data rate, the shorter the working distance of the cable

[0009] 4) There is no good way to solve different display resolutions: ordinary video signals are fixed resolutions based on pixels, and the prior art system can only send one resolution at a time

[0010] 5) No connector field crimping and locking: There are many conductors in HDMI, DVI and DP cables, making field crimping difficult

The HDMI connector has no locking function, making it unsuitable for important applications

[0011] 6) Star topology and installation difficulties: All of these standards use a star topology, with all sources and displays connected to a central switcher

[0029] The prior art SDI system is without HDCP (High-bandwidth Digital Content Protection) encryption, which is suitable for broadcast and video editing applications, but not suitable for professional and home electronics applications because there is no content protection
