- Sky Digital (UK & Ireland)
Sky Digital is the brand name for
British Sky Broadcasting's digital satellite televisionservice, transmitted from SES Astrasatellites located at 28.2°E (Astra 2A/2B/2C/2D) and Eutelsat's Eurobird 1satellite at 28.5°E.
BSkyB's analogue broadcasts ceased in
2001, so the service is now more commonly marketed as just Sky.
Sky Digital was officially launched on
1 October 1998, although small-scale tests were carried out before then. For the first time, BSkyB used the newly-launched Astra 2 satellites, which have since come to broadcast exclusively to the United Kingdomand the Republic of Ireland. At this time the use of the Sky Digital brand made an important distinction between the new service and Sky's analogue services. Key selling points were the improvement in picture and sound quality, increased number of channels and an interactive service branded Open..... Sky Digital competed with the ONdigital (later ITV Digital) terrestrial offering.
New Astra satellites joined the position in
2000, and the number of channels available to customers increased accordingly. This trend continued with the launch of Eurobird 1 in 2001.
Originally Sky Digital launched with a set top box known as the Sky digibox, however, in more recent years the
Sky+and Sky+ HDboxes have launched alongside the original box. Sky+ is a digital video recorderwith an internal hard drivewhich allows viewers to 'pause live television' (by switching from a live feed to a paused real-time recording that can be restarted at any point) and schedule programs to record in the future. Sky launched HDTV services in May 2006. The first photos of a prototype Sky HD receiver began appearing in magazines in August 2005. All Sky+ HD receivers incorporate a version of Sky Plus using a 300GB hard drive (of which 160GB is available to the user) to accommodate the necessary extra data. The rest of the hard drive is now used by Sky Digital set top boxes to store up to 30 hours of Anytime TV from the previous week.
Additionally, some channels occasionally receive new numbering — However, in early 2006, the majority of channels received new numbering, with some receiving single digit changes, whilst others received new numbers entirely.
Slogans Sky have used for marketing include "What do you want to watch?", "Entertainment your way" and the current slogan "Believe in better".
interactive service by broadcasting looping video streams.
Provided a universal
Ku bandLNB (9.75/10.600GHz) is fitted at the end of the dish and pointed at the correct satellite constellation, most digital receivers will receive the free to air channels. Some broadcasts are free-to-air and unencrypted, some are encrypted but do not require a monthly subscription (known as free-to-view), some are encrypted and require a monthly subscription, and some are pay-per-view services. To view the encrypted content a VideoguardUK equipped receiver (all of which are dedicated to the Sky Digital service, and cannot be used to decrypt other services) needs to be used. Unofficial CAMs are now available to view the service, although use of them breaks the user's contract with Sky and invalidates the user's rights to use the card.
BSkyB has no veto over the presence of channels on their EPG, with open access being an enforced part of their operating licence from
Ofcom. Any channel which can get carriage on a suitable beam of a satellite at 28 East is entitled to access to Sky's EPG for a fee, ranging from £15-100,000. Third-party channels which opt for encryption receive discounts ranging from reduced price to free EPG entries, free carriage on a Sky leased transponder, or actual payment for being carried. However, even in this case, Sky does not carry any control over the channel's content or carriage issues such as picture quality. Recent years have seen the launch of numerous low-budget channels, including foreign and shopping channels, often with very poor technical quality.
Sky recently stopped taking channel launch applications for its Electronic Programme Guide (EPG). Ofcom has said that this will give existing channels an unfair advantage and may force Sky to replace older set-top boxes for customers with the newer ones.
Due to either limited regional availability of certain channels, or conditions relating to their
must-carrystatus, Sky operate four regional variations of their EPG for domestic customers. The four different EPGs transmitted are: Republic of Ireland, Northern Ireland, Wales and England/Scotland. The Northern Irish EPG has the most listed channels, with the Republic of Ireland having the least, the difference is major as Five and BBC Radio are missing. Much of the missing content for Irish viewers is available through 'Other Channels' but Sky + viewers cannot record from 'Other Channels'. These missing channels are a bone of contention for Irish viewers, who are often forced to seek out Grey marketUK Sky cards if they want the missing channels. Each viewing card or smartcard provided by Sky is programmed with the customer's postcode, so when inserted into the user's set-top box it selects which EPG is used, as well as determining which regional variation is allotted to the BBC One, BBC Twoand ITVchannels for users of the England/Scotland EPG. Following a disagreement with the BBC after the launch of Sky Digital, all regional variations of BBC One and BBC Two are available to all UK viewers on channels 971-992.
All channels are
pay-tvchannels on Sky's "Sky World" package, unless stated.
