The Slingbox is a TV streaming media device made by Sling Media that encodes local video for transmission over the Internet to a remote device (sometimes called placeshifting). It allows users to remotely view and control their cable, satellite, or personal video recorder (PVR) system at home from a remote Internet-connected PC, smartphone or tablet as if he or she were at home.

Customers have also connected their Slingboxes to other video sources, including Blu-Ray players and security cameras.[1]



The traditional Slingbox embeds a video encoding chip to do real-time encoding of a video and audio stream into the SMPTE 421M / VC-1 format[2] that can be transmitted over the Internet via the ASF streaming format. Later Slingboxes also support Apple's HTTP Live Streaming,[3] which requires support for H.264.

The Slingboxes up until the Fourth Generation (or Next Generation Slingbox) used a Texas Instruments chipset.[4] Current generation Slingboxes and OEM products are built around a ViXS chipset.[5][6]

Control of the hosting video device, usually a set top box, is done through an IR blaster, which, on older Slingboxes, required the use of a IR blaster dongle. Current generation Slingboxes have built in IR blasters on the box itself, though customers can opt to continue to use the IR blaster dongle.

All Slingboxes include an Ethernet port that connects to a local network and out to the Internet. The Slingbox 500 is the first to include built-in Wi-Fi.

Cloud Infrastructure[edit]

Sling uses a Amazon Web Services-based infrastructure[7] to support encoding, relaying streams and analytics. It also sources data from multiple repositories to help guide recommendations to users, including social networks (Facebook and Twitter) and specialty services like Thuuz for sports.[8][9]

This infrastructure also allows Sling to report on aggregate television watching behavior. They have released several infographics[10][11] and provide a Nielsen-like weekly report of the top shows.[12]


Watch Client[edit]

Viewing content from a Slingbox requires a client application on the remote PC, smartphone or tablet. Included with the purchase of Slingbox is access to the Slingbox Watch website, which is a NPAPI-based browser plug-in for Microsoft Internet Explorer, Mozilla Firefox, Google Chrome and Apple Safari.[13] This website experience includes the ability to view and control your set top box, an integrated electronic program guide (US/Canada only) and the ability to manage your connected Slingboxes. A registered Sling account is required to access the Watch website.


In addition to the Watch Slingbox website, customers can purchase a SlingPlayer app for their mobile device. Supported platforms include iOS (iPhone and iPad), Android (phones and tablets), Kindle Fire and Microsoft Windows 8.1 tablets.[14] Previously supported platforms include Blackberry, PalmOS and Symbian. The launch price for SlingPlayer apps was $29.99. The price was reduced to $14.99 when the Slingbox 350 and 500 were launched in October 2012.

Apple iPhone, iPod Touch Controversy[edit]

SlingPlayer Mobile for iPhone was demonstrated at Macworld Expo 2009 in January and became available in May of the same year.

The announcement of the iPhone and iPod Touch application began a controversy among owners of older Slingboxes as Sling Media has announced that only the Slingbox SOLO, Pro and PRO-HD models will be supported by the iPhone client. Older Slingbox models Classic, Tuner and AV are not officially supported, although they do appear to work with the application nonetheless.[15]

On May 12, 2009, the SlingPlayer App became available at the Apple App Store, but only for US, Canadian and UK accounts, and was originally restricted to Wi-Fi for streaming content.[16] Sling's promotional email confirmed that the SlingPlayer for iPhone works with Wi-Fi connections only "At Apple's request" – a decision believed to have been made at the behest of incumbent iPhone network operators such as AT&T and O2. AT&T later relented to allow the app to stream over its cellular network. [17] This change was done 100% by AT&T as the SlingPlayer App already features quality scaling of content based on connection type.[18]

Apple iPad and Second Screen[edit]

On November 2010, Sling Media announced the release and immediate availability of the SlingPlayer Mobile app for the iPad.[14] The iPad-specific app takes full advantage of the iPad's large screen by offering a higher resolution stream than on other devices with smaller screens.

In November 2013, Sling released a redesigned SlingPlayer for iPad[19] that incorporates many second screen capabilities.

Microsoft Windows 8[edit]

Historically, Microsoft Windows Mobile and Windows Phone 7 platforms were supported. Sling released a native version for the Windows 8 platform in December 2013.[20] This version supports both Windows RT and Windows x86 for tablets, laptops and hybrids.
