Draka Prysmian Group 4K TECHNOLOGY

4K BROADCAST SIGNALS AND INFRA STRUCTURE

Today’s broadcasters' infrastructure is designed for 720p, 1080i or even 1080p video content. The important question for broadcasters looking at the infrastructure is what will be the future content and will it affect my infrastructure. For example, the typical infrastructure of an outside broadcast truck is the coaxial cable 0.6/2.8AF. For a stadium it is the coaxial cable 1.4/6.6AF or 1.6/7.3AF.

RESOLUTION 4K
3840 x 2160 progressive scan, the bit rate is 12Gb/s.
The high bandwidth of 12 Gb/s (4 times 3G /1080p) reduces the transmission length dramatically.

Three different 4K solutions for broadcast production are in discussion:
1. Single link (1x12Gb/s, 1/2 clock frequency = 6GHz)
2. Dual link (2x6Gb/s, 1/2 clock frequency = 3GHz)
3. Quad link (4x3Gb/s, 1/2 clock frequency = 1.5GHz)

The dual link and quad link solutions will solve the issue with the high bandwidth for new installation. To know the 4K situation of an existing broadcast infrastructure, we have to look at the single solution.
The latest SMPTE calculation is based on a maximum allowed attenuation of 40dB/100m at ó clock frequency.
The increase of the maximum allowed attenuation from 20 dB (known from SMPTE 292M and SMPTE 424M) to 40dB at 4K enables a maximum transmission length of 0.6/2.8AF up to 41m. For the technical realization it is essential to check the equipment e.g. equalizers if they are suitable for 4K to achieve the maximum values.

IPTV
To realize future broadcast infrastructure, several solutions are under discussion and development. AVB (Audio Video Bridging) and SMPTE 2022 are two of them, pushed by different suppliers.
But the discussions are going on: Maybe 4K is not enough, maybe 8K is the right one? And please don’t forget 3D, and if we are talking about a user friendly 3D the best solution would be without 3D glasses…
Which broadcast infrastructure, i.e. which cable construction, can handle this explosion of data rate?
We can expect copper cables are limited in transmission distance due to the huge bandwidth, while optical cables have almost no limitations.

DRAKA COXIAL CABLE FOR TRANSMISSION OF 4K SIGNALS COXIAL CABLE GOES 4K

There is currently a discussion on higher data rate on the market. 4K is playing an ever-increasing role in this. Currently, 4K transmissions in Quad Link (4 x 3 Gbit/s) are carried out for technical reasons. In practice, however, this proves to be uneconomical. Single-link transmission at 12 Gbit/s should be aimed for.

According to SMPTE ST 2082, the 4K format transmits video signals with a resolution of 3840 x 2160 pixels. Data transmission takes place with a rate of 12 Gbit/s. This corresponds to a half clock frequency of 6 GHz. The standard also provides for a maximum allowed attenuation of 40 dB. Draka has developed coaxial cables for 4K applications based on these specifications. For example, the new UHD series includes the UHD50 and UHD100.

In developing the new series, Draka has placed great emphasis on meeting the requirements of OB truck manufacturers, such as maintaining the outer cable diameters of 4.5 and 7 millimeters. Draka has achieved this through higher dielectric foaming and a silver-plated, size-optimized, inner conductor.

The quality of the components is of decisive importance in the technical implementation. To achieve maximum results, connectors and cables should be matched to each other. Tolerances must be kept as low as possible.

It should also be taken into account that different generations of equalizers are installed in the input board of the devices. These have a significant influence in determining the maximum achievable cable length.

Today’s broadcasters' infrastructure is designed for 720p, 1080i or even 1080p video content. The important question for broadcasters is what will be the future content and will it affect my infrastructure.

VIDEO CONTENT 1.5G:
The HD-SDI signal is defined by SMPTE292M. This content is like the SDI signal an uncompressed component signal, serial transmitted via one coaxial cable. The resolution of 1080i is 1080 lines x 1920 pixel. The resolution of 720p is of course 720 lines x1280 pixel and the bit rate is 1.485Gbit/s. Based on the SMPTE 292M specification a maximum transmission distance of an 0.6/2.8AF is 70m plus a headroom. Practical tests showed 90m.

VIDEO CONTENT 3G:
The HD-SDI signal is defined by SMPTE424M. The resolution is 1080 lines x1920 pixel, the scan is progressive; the bit rate is 3Gbit/s. Identical to SMPTE292M, the maximum transmission length is specified at maximum 20dB attenuation at half clock frequency. Based on these key points, the maximum transmission distance of a 0.6/2.8AF network is 47m plus headroom, practical test 80m.
