Methods of delivering TV channels

UHD channel:


Satellite reception of the channel is possible using transponder No. 34 of the Eutelsat 36A/36B/36C satellite @ 36° East:


Carrier frequency: 12.360 GHz (Transponder No. 34)
Polarization: right
Data transmission standard: DVB-S2
Modulation: 8PSK
Symbol rate: 30,000 Ks/s
Error correction code (FEC): 5/6
Coding: H.265 (HEVC)
Scrambling: DRE4 (Exset) 

What 4K is and how to retransmit it to cable networks.

From Wikipedia:

Ultra-high definition television (also known as UHDTV):

a type of television resolution standard that provides image clarity

several times higher than both standard and high-definition television, as well as

higher than most modern cinematic standards. Other names: Ultra HD and

Ultra High Definition Video (UHDV). Ultra-high definition television includes

two digital standards 4K UHDTV (2160p) and 8K UHDTV (4320p), which were proposed by NHK Science &

Technology Research Laboratories and approved by the International Telecommunication Union in

August 2012, as recommended by
ITU-R BT.2020


1HDTV is the exclusive distributor of the Insight UHD 4K channel.

“...the 4K content of the Insight channel requires 12-bit color,

which corresponds to the parameters of the most advanced 4K TVs. The extended dynamic

chromaticity range ensures more gradations of colors on the screen and prevents parts of the image

from being over-lit and darkened, thus revealing color gradations and

and the fine structure of the subject matter instead. Many experts see further development of

TV signal playback technologies in the area of HDR (HDR-High Dynamic Range)” (N. Orlov: link to the interview)

To descramble the channel from the NSK operator (a Tricolor project, no channel operator in the Siberian project),

a standard professional module is used with a conditional

access card which has a special subscription class attached.

A distinctive feature of the channel is that it is encoded by the next-generation

H.265 standard encoder (HEVC), which is more efficient in terms of signal compression at a 

comparable level of quality. The HDMI standardization in version 1.4 provides for two types of 4K:

Quad HD, 3840 x 2160 (corresponds to 16:9 aspect ratio of modern TVs)
4К-2К, 4096 х 2160
Both standards are designated Ultra High Definition.

Most (if not all) head stations of cable and IP operators do not have

professional receivers with a built-in H.265 (HEVC) decoder. This

is primarily due to the insufficient supply of such equipment

on the Russian market today.

Still, there are a number of cable operators who have already successfully received and retransmitted the channel to cable networks. Reception is ensured using the standard equipment

of head stations supporting the reception of SD and HD channels. In this respect,

there are no special features for receiving the Insight UHD 4K channel (DVB-S2, 8PSK).

However, there are a few simple steps you need to take to receive the Insight UHD 4K channel from satellite,

as follows:

accept a satellite channel with the above parameters;
descramble it using a professional module with an additional subscription class attached;
transmit it to the cable network without decoding it. 

Is it possible to retransmit the Insight UHD 4K channel on a cable network?

A simple calculation of the required bandwidth shows the following:

for QAM 64, it is 6.89*6=41.34 Mbit/s. The useful band remaining is 41.34*188/204=38.1

Mbit/s. If you have QAM 128 or 256, then there will be even more space to add

multiple SD channels with an average 4K channel bitrate from a satellite at 25 Mbit/s.



The list of TVs that support Insight UHD 4K channel decoding is taken from one

of the thematic conference sources on the Internet. According to this list,

we can be sure about the Samsung UHD 50 HU 7000 TV, since it is used in the 1TVCH monitoring system

and works properly. As for other models, they should be checked

or confirmed from reliable sources, but there is hope that all models of later versions

(such as Samsung 7500, 8500, 9000) work properly


At the moment, the situation with household receivers is even more uncertain. With our expertise, we can

advise only the VU+ Solo 4K model that is present on

the Russian market. This has been tested by 1TVCH and is used in the monitoring system.

A distinctive feature of this model is the availability of a transcoder

from HEVC to MPEG 4 (AVC), which allows you to simultaneously convert and record a channel

into MPEG4 (AVC) at a speed of up to 10 Mbit/s while receiving a channel online from a satellite.

When this receiver is connected to a 4K TV via the HDMI 2.0 interface,

the descrambled video of the Insight UHD 4K channel will be shown successfully.
