Intelsat 907 at 27.5° West

The main PSB channels from the BBC, ITV and Channel 4 are available on Intelsat 907 at 27.5° West.
This service is a backup for Freeview and carries PSB channels from the BBC, ITV, Channel 4 and Channel 5.
It is often referred to by its network name BBC-SATBACK.

It is a a backup of Freeview multiplexes PSB 1 and PSB 3, it is not intended for direct-to-home (DTH) reception.
All the channels including radio are encrypted using the BISS encryption system.
Using keys for a service that is not available in your country is illegal, that said, would anyone (apart from British Expats), be interested in this service?

The Symbol Rate used 44100, is rather high and unusual, though even the cheapest DVB-S2 satellite receivers these days, can handle the unusual Symbol rate used by the service.
There have been reports of problems with the HD channels, video can be viewed, though no audio is available.

To obtain audio on HD channels, AAC sound codec must be Switched on or a plugin installed. 
If you are using a Sat PC S2 DVB card, only update plugin AAC sound codex, that said, many HD receivers work without any audio problems.
Screen resolution is reported to be either 544 x 576 or 720 x 576 for standard definition channels in MPEG-2 and 1920 x 1088 for high definition channels in MPEG-4.

The service uses Spot 2 on the Intelsat 907, this covers most of northern Europe, the Iberian peninsula, and some areas of north Africa (Morocco). Reception may also be possible in the Canary Islands. It is operated by Aquiva.

Encryption

transponder-satbackBISS is a rather weak and old encryption system, this is not really a problem for the PSBs. However weak the system is, they are not breaking any copyright issues and there is no overspill. BISS keys do change from time to time, though not too often.

BISS (Basic Interoperable Scrambling System) is a simple scrambling system to be used in DSNG, Satellite Contribution and Primary Distribution applications.
Using the DVB-CSA (Common Scrambling Algorithm), BISS is an encryption standard that was agreed upon in January 2000 by a group of professional codec vendors and the European Broadcasting Union.

The system enables operators to transmit and receive scrambled signals to and from different encoders and IRDs. BISS requires no expensive and complicated CA system as a password is directly entered into the encoder and the IRD.
See the following websites for further information:
http://www.sciatl.com/customers/white-papers/BISS.pdf
http://www.ebu.ch/tech_32/tech_t3292.html

BISS uses a fixed Session Word (SW, 12 digit hex) and DVB-CSA for encryption. The Session Word  is used to derive a Control Word (CW 64 bit) for DVB-CSA.
Programs like ProgDVB and MultiDec have DVB-CSA builtin. Others use a CSA or SoftCSA plugin DLL.
