In June 2011, Comedy Central HD, Nickelodeon HD and N24 HD joined service, bringing the number of channels offered to 11. In April 2011, HD+ became available to Sky Deutschland subscribers without the need for an HD+ CAM and viewing card (although an additional subscription is still required). Currently (as of May 2012) all satellite HDTV channels are broadcast using the h.264 codec. As of July 2014, most material is upscaled SD content. Free-to-air HDTV via satellite Prior to 30 April 2012 there were eight free-to-air HDTV channels originating in Germany broadcast via satellite: Das Erste HD, ZDF HD, Arte HD, Anixe HD, EinsFestival HD, sonnenklar.TV HD, QVC HD and HSE24 HD. After 30 April 2012, when all analogue satellite broadcasts ceased, ten additional FTA HD channels became available (all of which are public service channels): Phoenix HD, NDR HD, WDR HD, BR HD, SWR HD, ZDFneo HD, ZDFinfo HD, ZDFkultur HD, 3sat HD and KiKa HD.

Due to this, the new owners of Deutsche Telekom's cable network were in many cases not able to offer new products directly to the viewer. By 2006, there were three major cable operators, Unity Media in Hesse, North Rhine-Westphalia and Baden-Württemberg and by far the largest, Kabel Deutschland in the other 13 states. Today, all companies offer about 200 TV channels by DVB-C, which includes some 70 channels at no extra charge as well as a number of pay-per-view offers and subscription-based packages (like the HD-broadcasts of privately owned channels, comparable to HD+ on satellite). In addition to that pay TV broadcaster Sky Deutschland is also available. In some very large apartment complexes a number of local and national companies operate an in-house cable network which is fed solely by its own satellite antenna on the building, not the local cable operator.
