xdi systems, devices, connectors and methods

Abstract

The present invention provides systems, devices, software, connectors and methods for transmitting compressed audio and video signals in a local system, which greatly reduces the bandwidth requirements, greatly reduces costs, and can transmit very long distances with cables. There is a high degree of system flexibility (eg link topology and scalability), using a single coaxial cable for simplicity and ease of use, or network cable, wireless, Internet and connectors, but not as much There are uncompressed digital systems such as HDMI, DVI, DP or SDI that produce any more signal quality loss or delay. The present invention also provides a solution for introducing uncompressed audio and video data and Internet data into the system. These systems, devices, connectors and methods are collectively referred to as "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 incorporated herein 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 wire , and devices that use very low data rate compressed audio-video signals with very low bandwidth requirements for much lower cost and higher reliability, and offer flexible system topologies (star or daisy chain or their the mix of). The new standard and corresponding electronic equipment and software will sound exactly the same as existing uncompressed standards such as HDMI (High Definition Multimedia Interface), DVI (Digital Visual Interface), DP (Display Interface) and SDI (Serial Digital Interface). and image quality.

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 Data Protection) encryption, which is suitable for broadcast and video editing applications, but not suitable for professional and home electronics applications because there is no data protection
