The Digital TV Group, the industry association for digital television in the UK, is responsible for co-ordination between Freeview and other digital services.
The original Freeview was later expanded with additional facilities (Freeview+), high-definition channels (Freeview HD), and Internet connectivity (Freeview Play). All services remain available; the original Freeview equipment will work (unenhanced) in the same way it always did.
The original Freeview service allowed a large number of digital television channels to be received on a compatible television receiver, set-top box, or personal video recorder. An electronic programme guide was available. Freeview channels are not encrypted and can be received by anyone in the UK. There is no additional charge to receive Freeview but it is a legal obligation to hold a current television licence to watch or record TV as it is being broadcast.
A subscription-based DTT service, Top Up TV, launched in March 2004. The Top Up TV service was not connected with the Freeview service, but ran alongside it on the DTT platform and was included in the Freeview EPG; programmes could be received on some Freeview set-top boxes and televisions equipped with a card slot or CI slot. The service also worked with existing ex-ONdigital / ITV Digital boxes that received the Freeview package; subscribers with those boxes had to insert their TopUp TV card into the slot which was originally used for inserting ONdigital / ITV Digital smartcards. Top Up TV was replaced in 2006, by a service that did not run on Freeview equipment. In October 2013, the TopUp TV service was closed down.

The Freeview logo certification for standard definition (SD) receivers and recorders was withdrawn in January 2017.
Freeview HD
Freeview HD comprises a number of high-definition versions of existing channels. It requires a different high-definition tuner, and does not supersede or replace standard Freeview.
On 20 August 2020, Freeview announced that it would phase out their Freeview HD brand in 2022.
Channels
With two channels (BBC HD and ITV HD) Freeview HD completed a "technical launch" on 2 December 2009 from Winter Hill (as a full power service) and Crystal Palace (as a reduced power temporary service). It operates on multiplex BBC B (aka Multiplex B or PSB3). The service was broadcast to all regions by the end of 2012. Channel 4 HD commenced test broadcasts on 25 March 2010 with an animated caption, ahead of its full launch on 30 March 2010, coinciding with the commercial launch of Freeview HD. S4C Clirlun launched on 30 April 2010, in Wales, where Channel 4 HD did not broadcast. STV HD launched in Scotland, where ITV HD does not broadcast, on 6 June 2010. S4C Clirlun closed on 1 December 2012, allowing Channel 4 HD to begin broadcasting in Wales.
Five HD was due to launch during 2010 but was unable to reach 'key criteria' to keep its slot. Spare allocation on multiplex B was handed over to the BBC, two years from the date when it was anticipated that further capacity on multiplex B would revert to the control of the BBC Trust. On 3 November 2010, BBC One HD launched on Freeview HD. Initially it was available in addition to the existing BBC HD channel, which continued to show the "best of the rest" of the BBC in HD. However, BBC HD was replaced by BBC Two HD on 26 March 2013.
Until 17 October 2011, the commercial public service broadcasters had the opportunity to apply to Ofcom to provide an additional HD service from between 28 November 2011 and 1 April 2012. Channel 5 HD was the sole applicant, with the aim of launching in spring or early summer 2012. On 15 December 2011, Channel 5 dropped its bid to take the fifth slot after being unable to resolve "issues of commercial importance". Subject to any future Ofcom decision to re-advertise the slot, the capacity will remain with the BBC and can be used by it for BBC services or services provided by a third party via a commercial arrangement. The BBC temporarily used the space to broadcast a high definition simulcast of their main Freeview red button feed for the duration of the 2012 Summer Olympics, followed by a channel from Channel 4 for the 2012 Summer Paralympics. On 13 June 2013, the BBC temporarily launched a high-definition red button stream in the vacant space.
On 16 July 2013, Ofcom announced that up to 10 new HD channels would be launched by early 2014, using new capacity made available by the digital switchover. This provided additional spectrum in the 600Mhz band for additional DVB-T2 multiplexes, reaching up to 70% of the UK population. At the same time, the BBC announced that they would provide five new HD channels due to the newly available capacity: BBC Three HD, BBC Four HD, CBBC HD, CBeebies HD and BBC News HD. BBC Three HD and CBBC HD launched to all viewers on 10 December 2013 using the capacity released by the Red Button HD service, and the other BBC channels launched in some regions, expanding to 70% UK coverage by June 2014.
Channel 5 HD launched on Freeview on 4 May 2016.
In June 2022, it was announced that the COM7 multiplex would be closing due to the licence expiring and the frequency used being released for 5G. The BBC announced that they have made provisions for a 6th slot for BBC Four HD and CBeebies HD to move into available capacity that has been newly identified on the PSB3 multiplex which the BBC operates. However, BBC News HD would stop being broadcast on Freeview.
Technical
The Digital TV Group publishes and maintains the UK technical specification for high-definition services on digital terrestrial television (Freeview) based on the new DVB-T2 standard. The specification is known as the D-book. Freeview HD is the first operational TV service in the world using the DVB-T2 standard. This standard is incompatible with DVB-T, and can only be received using compatible reception equipment. Some television receivers sold before the HD launch claimed to be "HD-ready", but this usually implies that the screen can display HD, rather than that DVB-T2 signals can be received – a suitable tuner (typically built into a STB or PVR) is additionally required. Freeview HD set-top boxes and televisions are available. To qualify for the Freeview HD logo, receivers will need to be IPTV-capable and display Freeview branding, including the logo, on the electronic programme guide screen. The Freeview HD trademark requirements state that any manufacturer applying for the Freeview HD logo should submit their product to the Digital TV Group's test centre (DTG Testing) for conformance testing.
On 2 February 2010, Vestel became the first manufacturer to gain Freeview HD certification, for the Vestel T8300 set top box. Humax released the first Freeview HD reception equipment, the Humax HD-FOX T2, on 13 February 2010.
It was announced on 10 February 2009, that the signal would be encoded with MPEG-4 AVC High Profile Level 4, which supports up to 1080i30/1080p30, so 1080p50 cannot be used. The system has been designed from the start to allow regional variations in the broadcast schedule. Services are statistically multiplexed – bandwidth is dynamically allocated between channels, depending on the complexity of the images – with the aim of maintaining a consistent quality, rather than a specific bit rate. Video for each channel can range between 3 Mbit/s and 17 Mbit/s. AAC or Dolby Digital Plus audio is transmitted at 384 kb/s for 5.1 surround sound, with stereo audio at 128–192 kbit/s; audio description takes up 64 kbit/s, subtitles 200 kbit/s and the data stream, for interactive applications 50 kbit/s. Recording sizes for Freeview HD television transmissions average around 3 GB per hour. Between 22 and 23 March 2011, an encoder software change allowed the Freeview version of BBC HD to automatically detect progressive material and change encoding mode appropriately, meaning the channel can switch to 1080p25. This was extended to all of the other Freeview HD channels in October 2011.
To ensure provision of audio description, broadcasters typically use the AAC codec. Hardware restrictions allow only a single type of audio decoder to operate at any one time, so the main audio and the audio description must use the same encoding family for them to be successfully combined at the receiver. In the case of BBC HD, the main audio is coded as AAC-LC and only the audio description is encoded as HE-AAC. Neither AAC nor Dolby Digital Plus codecs are supported by most home AV equipment, which typically accept Dolby Digital or DTS, leaving owners with stereo, rather than surround sound, output. Transcoding from AAC to Dolby Digital or DTS and multi-channel output via HDMI was not originally necessary for Freeview HD certification. As of June 2010 the DTG D-Book includes the requirement for mandatory transcoding when sending audio via S/PDIF, and for either transcoding or multi-channel PCM audio when sending it via HDMI in order for manufacturers to gain Freeview HD certification from April 2011. Thus equipment sold as Freeview HD before April 2011 may not deliver surround sound to audio equipment (some equipment may, but this is not mandatory); later equipment must be capable of surround sound compatible with most suitable audio equipment.
In early February 2011, it was announced that one million Freeview HD set-top boxes had been sold.
Copy protection
In August 2009, the BBC wrote to Ofcom after third-party content owners asked the BBC to undertake measures to ensure that all Freeview HD boxes would include copy protection systems as required by the Digital TV Group's D-Book, which sets technical standards for digital terrestrial television in the UK. The BBC proposed to ensure compliance with copy-protection standards on the upgraded Freeview HD multiplex by compressing the service information (SI) data, which receivers need to understand the TV services in the data stream. To encourage boxes to adopt copy protection, the BBC made its own look-up tables and decompression algorithm, necessary for decoding the EPG data on high-definition channels, available without charge only to manufacturers who implement the copy-protection technology. This technology would control the way HD films and TV shows are copied onto, for example Blu-ray discs, and shared with others over the internet. No restrictions will be placed on standard-definition services. In a formal written response, Ofcom principal advisor Greg Bensberg said that wording of the licence would probably need to be changed to reflect the fact that this new arrangement is permitted. The BBC had suggested that as an alternative to the SI compression scheme, the Freeview HD multiplex may have to adopt encryption. Bensberg said that it would appear "inappropriate to encrypt public service broadcast content on DTT".
On 14 June 2010, Ofcom agreed to allow the BBC to limit the full availability of its own and other broadcasters' high definition (HD) Freeview services to receivers that control how HD content can be used. Ofcom concluded that the decision to accept the BBC's request will deliver net benefits to licence-holders by ensuring they have access to the widest possible range of HD television content on DTT.
Freeview HD Recorder
Freeview HD Recorder (formerly Freeview+, originally named Freeview Playback) is the marketing name for Freeview-capable digital video recorders with some enhancements over the original Freeview.
All recorders are required to include the following features in addition to standard Freeview:
At least eight-day electronic programme guide (EPG)
Series link (one timer to record whole series)
Record split programmes as one programme
Offer to record related programme
Record alternative showing if there is a time conflict
Schedule changes updated in standby (e.g. scheduled recording starting early)
Accurate Recording (AR, equivalent to PDC) – programmes are recorded based on signals from the broadcaster rather than scheduled time. (Since this is based on signals from the broadcaster, the broadcaster can prevent recording by sending nonsense signals as a form of copy protection, as already happens on music channels. However, this can be circumvented by specifying a timer recording instead of a programme recording or by connecting the receiver to a traditional videocassette recorder.)
Pace plc introduced the first DTT DVR in the UK in September 2002, called the Pace Twin. However, this was before the Freeview brand and its Playback and + marketing names were introduced.
Freeview Play
Freeview Play combines the existing live television service with catch-up TV (BBC iPlayer, ITVX, STV Player, Channel 4, S4C Clic, 5, U, CBS Catchup Channels UK, Legend) on a variety of compatible TV and set-top boxes via the user's standard broadband Internet connection. Its main purpose is to provide easy access to catch-up services by scrolling backwards on the traditional electronic programming guide (EPG); YouView is a similar but competing combination of live Freeview and catch-up using the EPG.
The technology is an open standard, but with prominent Freeview Play branding. The service launched in October 2015, on compliant equipment, initially 2015 Panasonic TV receivers and Humax set-top boxes, including existing models with a software update. Other manufacturers were announcing new models "later this year [i.e. 2015]". The 2017 specification for Freeview Play includes support for HDR video using hybrid log–gamma (HLG), when playing on-demand broadband content.
Mobile app
In 2019, Freeview released an app for iOS and Android devices. The app provides a TV guide for a limited number (23) of the Freeview channels and the ability to watch them via the various channel player apps: BBC iPlayer, ITVX, STV Player, Channel 4, 5 and UKTV Play. The user must install these apps and register on them. The app was criticised when released as "simply a shiny TV guide app". As of 2026 it remains unable to play content, requiring the different player apps such as iPlayer.
