Apple TV devices can play video, music, and podcasts, and since the fourth generation model download apps and games from the tvOS App Store. The first, second and third generation models offered limited content that Apple had provisioned to work with Apple TV. Software development for those models was discontinued after the release of the fourth generation Apple TV, with an OS based on
iOS called tvOS, which lets developers create their own apps for Apple TV. These include multimedia, music apps, and games. app for Apple TV Features of Apple TV include: ;Video streaming :*Users of Apple TV can rent or buy movies and TV shows from the
iTunes Store, or stream video from a variety of services found in the tvOS App Store. :*Users can stream live and on-demand content from apps that support login through a cable provider by way of one universal app also called
Apple TV. The single-sign on feature in tvOS 10.1 and later allows users to log in to all of these apps at once, bypassing the need to authenticate each individually. ;Music and Podcasts streaming :*Users can access their music and podcasts libraries that they purchased in iTunes through iCloud through the Music and Podcasts apps, respectively. In addition, users can also subscribe to music streaming services and access content that way. ;Photos :*The built in Photos app syncs user photos from
iCloud Photo Library and displays them on TV. In addition, users can download third-party apps like
Adobe Lightroom to view, edit and share them. ;Apps and games :*With the fourth generation Apple TV and later, users can download apps and games from the tvOS App Store. This app store is similar to the one found on the Apple
iPhone and
iPad. :*Apps can now be ported from iOS easily by developers since tvOS and iOS share a common codebase and kernel. :*:Examples include the
Papa John's and
Grubhub apps, which allows for users to order food right from Apple TV, and
Zillow, which allows users to search for homes right on their TV. A
NASA app for Apple TV includes live streaming of
NASA TV content, including
International Space Station missions. :*Games use the accelerometer and gyroscope along with the touchpad found on the Siri Remote for control. External Bluetooth game controllers can also be paired. :*:Examples include
Asphalt 8, which can be played using the Siri Remote. ;Casting and mirroring :*With
AirPlay, users can stream or mirror content wirelessly from an iOS device or Mac. AirPlay can be accessed by swiping up from the bottom of the screen (swipe down from top right on newer models) in Control Center on iOS or in the Menu Bar on a Mac. Its functions include: :**Casting, which allows users to wirelessly send video or audio from their iPhone, iPad, or Mac to the Apple TV. :**Mirroring, which allows users to wirelessly mirror their Mac screen or AirPlay device to the TV, using it as a second monitor. :**Peer-to-Peer AirPlay, which uses Bluetooth to connect if the Apple TV and the iOS Device/Mac are not on the same Wi-Fi network. ;Siri :*
Siri is built into the fourth generation and later Apple TV. It enables voice dictation in text fields, including usernames and passwords. Apple has been expanding the feature to encompass additional channels worldwide. :*A Live Tune-In feature that allows the viewer to ask
Siri to tune to live streams. ;HomeKit :*The third-generation Apple TV and later can also be used as a home hub to control HomeKit devices, such as locks, thermostats, or garage doors either locally or over the Internet. HomeKit Automation, such as automatic implementation of scenes, multiple user support, and using Siri to control devices, and remote access for shared users or HomeKit-enabled cameras is only possible with a fourth generation Apple TV or later. ;General :*HDMI CEC to control other devices in a user's home theater setup. :*App Switcher, which enables users to switch apps. :*Aerial Screensaver, which allows the TV to display a flyover view of a city when Apple TV is inactive. Screensavers can also be invoked from the home screen by pressing menu on the Siri Remote once.
App Store • With the fourth-generation Apple TV (Apple TV HD) and tvOS, Apple announced the App Store, which allows any developer to make apps, using the APIs available specifically tailored towards the TV. Also, since tvOS is based on iOS, any developer can port over apps from iOS and with a few modifications, as Apple stated on stage, and can make them available for all tvOS users with the App Store. The App Store is not available to previous Apple TVs and is a feature of the fourth generation Apple TV onward.
Accessibility Since tvOS and
watchOS are based on iOS, they have inherited many of the accessibility features of
iOS and
macOS and are compatible with Apple's entire product line including the
Apple Watch as a
remote controller for the Apple TV. tvOS includes the Apple technologies of
VoiceOver, Zoom, and
Siri to help the
blind and those with low vision. Pairing a
Wireless keyboard with the tvOS on the Apple TV enables another accessibility feature that also is an incorporation of VoiceOver. When typing, VoiceOver mirrors with an audio voice, each character pressed on the keyboard and repeated again when it is entered. The Apple TV HD and later can also work with the
Apple Wireless Keyboard or the
Apple Magic Keyboard. Apple TV with and without tvOS supports
closed captioning, so the deaf or hard of hearing can properly watch TV episodes and feature-length movies. Compatible episodes and movies are denoted with a CC (closed captioning) or SDH (Descriptive Audio) icon in the iTunes Store either on the Apple TV or in iTunes itself. The viewer can customize the captions in episodes or movies with styles and
fonts that are more conducive to their hearing and/or visual impairment. Apple's Remote app on iOS devices allows control of the Apple TV from an iPhone, iPad or iPod Touch.
Restrictions Similar to Google's redesign of YouTube, Apple has restricted access to most viewed charts on movies and podcasts. They are replaced by "Top Movies", "Top Podcasts", and "Editor's Picks". Parental controls allow consumers to limit access to Internet media service content via "Restrictions" settings; individual services can be turned off (e.g., to reduce clutter), icons can be rearranged via the tap-and-hold technique
à la iOS. Internet media is split into four categories: "Internet Photos", "
YouTube", "
Podcasts", and "Purchase and Rental". Each of the categories is configured by a parental control of "Show", "Hide" or "Ask" to prompt for a 4-digit PIN. In addition, movies, TV shows, music and podcasts can be restricted by rating.
Local sources Apple TV allows users on a computer running
iTunes to sync or stream photos, music and videos. A user can connect a computer on a local network to maintain a central home media library of digitized CD,
DVD or HD content, provide direct connectivity to photo organization software such as iPhoto, limit home video access to a local network only, play Internet radio, or preload content on Apple TV to be used later as a non-networked video player. Photos can be synced from
iPhoto,
Aperture, or from a folder on a
Mac, or Adobe Photoshop Album,
Adobe Photoshop, or from a hard disk folder in
Windows. Apple TV can also function as a
peer-to-peer digital media player, streaming content from iTunes libraries and playing the content over the network. First-generation Apple TVs can stream content from up to five computers or iTunes libraries. Also, five Apple TVs can be linked to the same iTunes library. The second-generation Apple TV onwards allows users to stream content from more than one iTunes library: these additional iTunes libraries can be on the same or on different computers. This is possible when Apple TV and every iTunes library from which you want to stream content meet all of the following conditions: (1) the Apple TV and the iTunes library you are streaming from are both on the same local network, (2) each uses the iTunes "Home Sharing" feature, and (3) each are using the same "Home Sharing" Apple ID. Apple TV HD and newer can also stream content locally using third-party apps such as
Plex,
Kodi,
VLC media player,
Emby and
MrMC.
Supported formats Apple TV natively supports the following audio, video, and picture formats (although with the Apple TV HD and later, apps may use alternative built-in software in order to play other codecs and formats, e.g.
Emby,
MrMC,
VLC media player,
Kodi and
Plex): Attempts to sync unsupported content to Apple TV will draw an error message from iTunes. The first- and second-generation Apple TV video output can be set to either
1080i or
1080p; this resolution is limited to the user interface and the viewing of photographs – all other content is simply upscaled to those resolutions. Those models cannot play 1080i or 1080p video content (e.g., HD camera video). The third- and fourth-generation Apple TV support 1080p video content. The Apple TV 4K, as the name suggests, supports 4K resolutions and HDR, including Dolby Vision. 4K content from sources such as iTunes can be played on a compatible 4K television set. Apple offers
AVC 1080p video content encoded at rates from 4 to 8 Mbit/s and
HEVC 4K video encoded at rates up to 30 Mbit/s through iTunes and the
TV app. In comparison, films on
Blu-ray are 1080p H.264 or
VC-1 video encoded at rates of up to 40 Mbit/s, while films on
Ultra HD Blu-ray are 2160p HEVC video encoded up to 128 Mbit/s. Apple TV's audio
chip supports 7.1
surround sound, and some high definition rentals from iTunes are offered with Dolby Digital 5.1 surround sound. There is an Apple TV export option in
QuickTime, which allows content in some formats that the device does not support to be easily re-encoded. Applications that use QuickTime to export media can use this; e.g.,
iMovie's Share menu, iTunes' advanced menu, and some third-party content conversion tools.
Connectivity Apple TV streams video through an
HDMI cable (Type A) connected to the TV's HDMI port.
Audio is supported through the
optical or HDMI ports. The device also has a
Micro-USB port, which is reserved for service and diagnostics. The device connects through
Ethernet or
Wi-Fi to the computer for digital content from the Internet and local networks. Apple TV does not come with audio, video or other cables, which must be acquired additionally as required. On the previous Apple TV, media files could be transferred directly onto the device by syncing with another computer. Once content was stored on the device's hard drive, Internet connectivity was no longer needed to view content. This is not the case with the later models, which do not have a hard drive for storing media. The first-generation Apple TV had
component video and
RCA connector audio ports, both removed in the 2nd generation. The device does not have
RCA/composite video or
F/RF connectors, but can be tricked into outputting color via composite. Starting with the Apple TV HD, Apple removed the
optical audio port. Apple also enhanced the HDMI port by adding support for
HDMI. The 4th generation also removed the
USB hardware port in favor of the reversible
USB-C port and the 5th generation removed USB entirely.
AirPlay AirPlay allows iOS devices or an
AirPort-enabled computer with the
iTunes music player to send a
stream of music to multiple (three to six, in typical conditions) stereos connected to an
AirPort Express (the audio-only antecedent of Apple TV) or Apple TV. The AirPort Express' streaming media capabilities use Apple's
Remote Audio Output Protocol (RAOP), a proprietary variant of
RTSP/
RTP. Using
WDS-bridging, the AirPort Express can allow AirPlay functionality (as well as Internet access, file and print sharing, etc.) across a larger distance in a mixed environment of wired and up to 10 wireless clients. Speakers attached to an AirPort Express or Apple TV can be selected from within the "Remote" iPhone/iPod Touch program, allowing full AirPlay compatibility (see "Remote control" section below). A compatible Mac running
OS X Mountain Lion or later can wirelessly mirror its screen to an Apple TV through AirPlay Mirroring while one running
OS X Mavericks or later can also extend its display with AirPlay Display.
Remote control Apple TV can be controlled by many infrared remote controls or paired with the included
Apple Remote to prevent interference from other remotes. Either kind of remote can control playback volume, but for music only. The
Apple Wireless Keyboard is supported on the second-generation Apple TV and later using the built-in
Bluetooth. The consumer has the ability to control media playback, navigate menus and input text and other information. Third-party keyboards that use the Apple layout may also be compatible. The
Apple Watch also has a remote app to control Apple TV. The Remote App was updated on September 13, 2016, to take advantage of all the features of the Apple TV 4. This includes Siri, Touchpad, and Home Buttons, along with a now playing screen. is included with the second generation 4K Apple TV and later, as well as being sold by itself. On September 9, 2015, Apple announced the new Siri Remote for the fourth-generation Apple TV (Apple TV HD) (although in some territories, Apple has kept the name Apple TV Remote, due to Siri functionality not being enabled on it in that territory). It is a completely redesigned remote that features dual microphones for
Siri support and a glass touch surface for navigation around the interface by swiping or tapping and scrubbing to fast forward or rewind. Also, it has a menu and home button, a Siri button to invoke Siri, a Play/Pause button, and a Volume Up/Down button to control the volume on the TV. The Siri Remote communicates with the Apple TV via Bluetooth rather than infrared, removing the requirement of a line-of-sight with the device. This new remote is only supported by the Apple TV HD and later and will not work with earlier generations.
Siri Beginning with the Apple TV HD, the remote includes two microphones and a button to activate
Siri. Siri on the Apple TV has all of the functions of Siri on iOS 9; it can also respond to requests specifically for the TV. For instance, the viewer can ask Siri to search for a TV show or movie and it will search across multiple different sources to tell the user where the content is available to watch. It can also do things such as Play/Pause, Rewind/Fast Forward, skip back 15 seconds and temporarily turn on captioning when asked "what did he say?" or "what did she say?", open a specific app, and more. == Software ==
