Space shifting (or spaceshifting), also known as place shifting (or placeshifting), allows media, such as music or films, which are stored on one device, to be accessed from another place through another device. Space shifting is frequently done through computer networks, for example by viewing a television broadcast from a WiFi equipped set-top box on a WiFi equipped notebook. Other media shifting processes include time shifting, a process whereby a radio or television broadcast is recorded and played back at a different time, and format shifting where media files are converted into different formats. [1]
A practical purpose of placeshifting is to avoid copyright infringement claims, as when viewing content through the Slingbox or similar consumer electronics.
In the 1980s, in the United States, Radio Shack marketed and distributed a different technology to view Audio/Video output remotely. It worked on the cordless phone frequencies and broadcast the signal with their proprietary transmitters and receivers branded Archer/Rabbit VCR Multiplying System.
Here are a few products and devices known for offering space shifting technology:
Wireless communication is the transfer of information (telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications involve other electromagnetic phenomena, such as light and magnetic or electric fields, or the use of sound.
A digital video recorder (DVR) is an electronic device that records video in a digital format to a disk drive, USB flash drive, SD memory card, SSD or other local or networked mass storage device. The term includes set-top boxes (STB) with direct to disk recording, portable media players and TV gateways with recording capability, and digital camcorders. Personal computers are often connected to video capture devices and used as DVRs; in such cases the application software used to record video is an integral part of the DVR. Many DVRs are classified as consumer electronic devices; such devices may alternatively be referred to as personal video recorders (PVRs), particularly in Canada. Similar small devices with built-in displays and SSD support may be used for professional film or video production, as these recorders often do not have the limitations that built-in recorders in cameras have, offering wider codec support, the removal of recording time limitations and higher bitrates.
Wi-Fi Protected Access (WPA), Wi-Fi Protected Access 2 (WPA2), and Wi-Fi Protected Access 3 (WPA3) are the three security certification programs developed after 2000 by the Wi-Fi Alliance to secure wireless computer networks. The Alliance defined these in response to serious weaknesses researchers had found in the previous system, Wired Equivalent Privacy (WEP).
A TV tuner card is a kind of television tuner that allows television signals to be received by a computer. Most TV tuners also function as video capture cards, allowing them to record television programs onto a hard disk much like the digital video recorder (DVR) does.
A home theater PC (HTPC) or media center computer is a convergent device that combines some or all the capabilities of a personal computer with a software application that focuses on video, photo, audio playback, and sometimes video recording functionality. Since the mid-2000s, other types of consumer electronics, including game consoles and dedicated media devices, have crossed over to manage video and music content. The term "media center" also refers to specialized application software designed to run on standard personal computers.
The Freebox is an ADSL-VDSL-FTTH modem and a set-top box that the French Internet service provider named Free provides to its DSL-FTTH subscribers.
Digital Living Network Alliance (DLNA) is a set of interoperability standards for sharing home digital media among multimedia devices. It allows users to share or stream stored media files to various certified devices on the same network like PCs, smartphones, TV sets, game consoles, stereo systems, and NASs. DLNA incorporates several existing public standards, including Universal Plug and Play (UPnP) for media management and device discovery and control, wired and wireless networking standards, and widely used digital media formats.
Beyond TV is digital video recorder/media center software for Microsoft Windows produced by the American company SnapStream. The software was originally released in 2000 as a Personal Video Station. Like most media center software, and devices such as TiVo and Sky+, Beyond TV has a 10-foot user interface design for the living-room TV. Allowing you to watch, pause and record live TV, as well as schedule recording. It also allows you to search for a show in its electronic program guide, enabling the user to find out when shows are on without having to search through the listings themselves.
Sony's LocationFree is the marketing name for a group of products and technologies for timeshifting and placeshifting streaming video. The LocationFree Player is an Internet-based multifunctional device used to stream live television broadcasts, DVDs and DVR content over a home network or the Internet. It is in essence a remote video streaming server product. It was first announced by Sony in Q1 2004 and launched early in Q4 2004 alongside a co-branded wireless tablet TV. The last LocationFree product was the LF-V30 released in 2007.
The Slingbox was a TV streaming media device made by Sling Media that encoded local video for transmission over the Internet to a remote device. It allowed users to remotely view and control their cable, satellite, or digital video recorder (DVR) system at home from a remote Internet-connected personal computer, smartphone, or tablet as if they were at home.
A home network or home area network (HAN) is a type of computer network that facilitates communication among devices within the close vicinity of a home. Devices capable of participating in this network, for example, smart devices such as network printers and handheld mobile computers, often gain enhanced emergent capabilities through their ability to interact. These additional capabilities can be used to increase the quality of life inside the home in a variety of ways, such as automation of repetitive tasks, increased personal productivity, enhanced home security, and easier access to entertainment.
Format shifting is the conversion of media files into different file format or data compression. This may be required to play the media on different devices, for example when converting or ripping audio files on CDs into digital formats such as MP3. Other media shifting processes include time shifting, a process whereby a radio or television broadcast is recorded to disk storage and played back at a different time, and space shifting where media is stored on one device and can be accessed from another place through another device which is normally located at another location.
In-flight entertainment (IFE) refers to the entertainment available to aircraft passengers during a flight. In 1936, the airship Hindenburg offered passengers a piano, lounge, dining room, smoking room, and bar during the 2+1⁄2-day flight between Europe and America. After World War II, food and drink services were offered, and movies were projected onto big screens viewable by all passengers on long flights. In 1985 the first personal audio player became available for purchase, and noise cancelling headphones were introduced in 1989. During the 1990s, the demand for better IFE was a major factor in the design of aircraft cabins. Before then, entertainment came via audio headphone sockets and airline-provided headphones providing music of various genres and the soundtrack of projected movies. Now, in most aircraft, personal IFE display screens are available at most seats, offering entertainment and flight information such as a moving map, speed, and altitude. The advent of small entertainment and communication devices also allows passengers to also use their own devices, subject to regulations to prevent them interfering with aircraft equipment.
TV2Me is a device that allows TV viewers to watch their home's cable or satellite television programs on their own computers, mobile phones, television sets and projector screens anywhere in the world. "This technology gives users the ability to shift space, and to watch all the cable or satellite TV channels of any place they choose - live, in full motion, with unparalleled television-quality - on any Internet connected device."
Sling Media Inc. is an American technology company that develops placeshifting and Smart TV solutions for consumers, multiple-system operators and set top box manufacturers. The company is based in Foster City, California, and was a subsidiary of Echostar. Their initial product, the Slingbox, debuted on the US market on July 1, 2005. The EchoStar business unit was part of a corporate assets exchange with Dish Network at the beginning of 2017 and now operates as Dish Technologies Corporation under Dish Network.
Monsoon Multimedia was a company that manufactured, developed and sold video streaming and place-shifting devices that allowed consumers to view and control live television on PCs connected to a local (home) network or remotely from a broadband-connected PC or mobile phone. It was one of 5 major transformations initiated by Prabhat Jain, a Silicon Valley entrepreneur with 5 undergraduate and post graduate engineering degrees from Cal Berkeley and Univ of Vienna, Austria. On the even of Cisco acquiring Monsoon in 2017, EchoStar, the new parent of Sling sued Monsoon for patent infringement, having obtained confidential information about the date of the acquisition by Cisco from a Monsoon employee under murky circumstances. Monsoon settled the lawsuit by agreeing not to sell its products in the USA simply because it did not have the legal funds to fight mighty Echostar's legal maneuvers. EchoStar thus successfully removed its only competitor from the market place. This meant Monsoon's death knell.
Eye-Fi was a company based in Mountain View, California, that produced SD memory cards with Wi-Fi capabilities. Using an Eye-Fi card inside a digital camera, one could wirelessly and automatically upload digital photos to a local computer or a mobile device such as a smartphone or tablet computer. The company ceased business in 2016.
The RVU protocol is an Application Layer protocol, that combines the pre-existing Digital Living Network Alliance (DLNA) standards and a new Remote User Interface (RUI) protocol, which works similar to Remote Desktop Protocol (RDP). The RVU RUI protocol is intended to allow an RVU-enabled client, such as a TV, to receive a pixel-accurate display of the user interface available on an RVU server.
