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.
