Subscriptions

A subscription to the HD Mix carries an extra fee of £10.25 on top of the standard Sky subscription. This fee allows customers to view all premium HD channels. SkyHD customers will only see the HD channels that correspond to the mixes they subscribe to. Thus, Discovery HD and National Geographic HD will only be available if you have the entertainment extra package in addition to HD. Before that someone without the Knowledge Pack (part of the entertainment extra of September 2011) cannot view the SD Discovery or National Geographic but they can view the HD versions.Additional Pay-Per-View events on Sky Box Office HD are not available to customers unless they subscribe to the Sky HD mix.

The HD package, like the sky TV has a one year minimum subscription and after this point an 31 day cancellation period is needed.

 recording facilities are included at no cost if a customer subscribes to any Sky package. Viewers who do not take a subscription channel package will still receive all free channels, but cannot use the recording facilities.

In Jan 2010, customers started being offered the Sky+ HD box as standard, and it is now optional to take the HD package. The HD package still remains at the same subscription price. The Sky+ box is no longer listed for purchase on the Sky website, and the Sky+HD is now classed as the standard box installation.

Sky says that it has found a number of Open Source Software developments that provide capabilities that benefit the software used in the Sky+ HD box.

Increase in HD channels

In over three years since launch, the number of HD channels available has increased significantly, thus Sky+ HD is the world’s largest HD offering outside North America.

The Sky+ HD Guide

Since the launch, the Sky+ HD EPG has been based upon the Sky Guide, which has changed little since the launch of Sky in 1998. For two years, Sky have been working on a completely new EPG exclusively for Sky+ HD boxes. This was first made available to customers with Thomson boxes in March 2009. As of December 9, 2009 all Thomson, Pace, Samsung and Amstrad models have been upgraded to the new EPG. Further information and details about the EPG are available on the Sky+HD Guide website, with a user guide on how to use the EPG and new instruction manuals for the boxes.

The channel listings will now be cached on the hard drive, freeing up the tuner so that users can continue to view programmes in a small Mini TV while browsing the TV Guide. The data being stored on the hard drive also means that loading times decrease and synopsis information can be displayed for channels other than the one you are watching. Other features include a significantly improved programme search system, A Series Stack which groups episodes of the same series together in the planner, and the ability to highlight HD programmes in the TV guide. The new EPG is also presented in 1080i, rather than the previous upscaled version.

As of 9 December 2009, All boxes have been updated to the new Guide.

The current EPG Software Version for Thomson boxes is Sky+ 8.3.2, for the Amstrad DRX780 it's 42.0.5.2_3 and for the Amstrad DRX890, Samsung and Pace boxes it's 47.0.16.1 and Amstrad DRX895 1TB it's 45.0.41.12
On 30 July 2009, Sky confirmed the launch of a ‘pull’ video-on-demand (VOD) service for 2010, adding to the current Sky Anytime ‘push’ VOD service. The service, delivered by broadband internet, will utilise the Ethernet port of existing Sky+ HD boxes. Sky's Anytime+ will only be available to Sky broadband at launch but sky say it will be on all service providers in the near future. Although the service may be similar to DirecTV

. “It will be a broad offering at launch with a large range of content across the range of content that we show,” CEO Jeremy Darroch said. “ (It will feature) progressive download using the broadband return pathway and the hard disc in a combined way. All of the boxes are VOD-ready, so we’ll be able to roll it out to all of the box population.” Sky Anytime+ began a staggered roll out from 26 October 2010. In march 2011 it was confirmed by sky that the Thomson sky hd boxes would not be suitable for the new anytime+ service. Customers with Thomson boxes are being offerd New boxes.

On 1 February 2011, BSkyB introduced a new EPG for Sky HD subscribers which switched the standard definition channels with the high definition simulcast. For example, Sky News HD, which was on channel 517, switched to channel 501. The same happened for other non-regional HD channels, including Syfy, Comedy Central, Sky Sports, E4 and Sky1.
