6. Single Cable Distribution—Unicable
Single Cable Distribution is a satellite TV technology that enables the delivery of broadcast
programming to multiple users over a single coaxial cable, and eliminates the numerous cables
required to support consumer electronics devices such as twin-tuner Digital Video Recorders (DVRs)
and high end receivers. Without single cable distribution, providing full spectrum access for multiple
receivers, or receivers with multiple tuners, in a single family home has required a separate coaxial
cable feeding each tuner from the antenna equipment (either multiple LNBs, a multi-output LNB or a
multiswitch distribution system) because of the large bandwidth requirement of the signals. A
European industry standard for distributing satellite signals over a single coaxial cable - CENELEC
EN50494 - has been developed by a consortium led by SES Astra. Unicable uses an integrated
software and hardware solution that allows Unicable-certified Digital Video Recorders and receivers
to multiplex selected programming when using Unicable LNB or multi-switching products.
Unicable LNB
Special LNBs have been developed for use in single cable distribution systems. The LNB further
includes a mixer to combine the user bands together and a microcontroller to receive the instructions
as to which frequency is required by each user and control the SCR chips.
How to:
1. Change the option in LNB Freq. to "Unicable
(10200)" or “Unicable(9750-10600).
2. The menu expanded and now you can find
the three new settings IF Channel. , Centre Freq
and Sat Position.
3. Now you can make the necessary
adjustments. Apply according to your cable
connection and the specifications of the Unicable
LNB. Change e.g. IF Channel to 1.
4. Select Centre Freq with the DOWN arrow
key.
5. Enter here for example the frequency of a
01210.
6. Confirm the entries by highlighting “Save”
and pressing the OK button.
Finish the Unicable setting, then enter the search menu to search the channels. It now appears
another query where you can specify additional search parameters (see previous pages). The
satellites are searched in order.
All received TV and radio stations are displayed in the two lists. After the scan, the TV and radio
stations in the two lists are stored and the unit goes into the live image of the first TV station.
