Digital television (DTV) is the transmission of television signals using digital encoding, in contrast to the earlier analog television technology which used analog signals. At the time of its development it was considered an innovative advancement and represented the first significant evolution in television technology since color television in the 1950s. Modern digital television is transmitted in high-definition television (HDTV) with greater resolution than analog TV. It typically uses a widescreen aspect ratio in contrast to the narrower format of analog TV. It makes more economical use of scarce radio spectrum space; it can transmit up to seven channels in the same bandwidth as a single analog channel, and provides many new features that analog television cannot. A transition from analog to digital broadcasting began around 2000. Different digital television broadcasting standards have been adopted in different parts of the world; below are the more widely used standards:
Integrated Services Digital Broadcasting is a Japanese broadcasting standard for digital television (DTV) and digital radio.
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 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.
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.
Hauppauge Computer Works is a US manufacturer and marketer of electronic video hardware for personal computers. Although it is most widely known for its WinTV line of TV tuner cards for PCs, Hauppauge also produces personal video recorders, digital video editors, digital media players, hybrid video recorders and digital television products for both Windows and Mac. The company is named after the hamlet of Hauppauge, New York, in which it is based.
MediaPortal is an open-source media player and digital video recorder software project, often considered an alternative to Windows Media Center. It provides a 10-foot user interface for performing typical PVR/TiVo functionality, including playing, pausing, and recording live TV; playing DVDs, videos, and music; viewing pictures; and other functions. Plugins allow it to perform additional tasks, such as watching online video, listening to music from online services such as Last.fm, and launching other applications such as games. It interfaces with the hardware commonly found in HTPCs, such as TV tuners, infrared receivers, and LCD displays.
The Broadcast Driver Architecture (BDA) is a Microsoft standard for digital video capture on Microsoft Windows operating systems. It encompasses the ATSC and DVB standards and gives developers a standardized method of accessing TV tuner devices. It is the driver component of Microsoft TV Technologies, and is used by hardware vendors to create digital TV tuning devices for Windows, and also to support new network types or custom hardware functionality. BDA is documented in the Windows DDK and the Platform SDK. Ideally, any BDA-compliant software should be compatible with any BDA-compliant hardware.
ShowShifter, now obsolete, was a proprietary, commercial digital video recorder (DVR) and home theater PC (HTPC) software for Windows.
An ATSCtuner, often called an ATSC receiver or HDTV tuner, is a type of television tuner that allows reception of digital television (DTV) television channels that use ATSC standards, as transmitted by television stations in North America, parts of Central America, and South Korea. Such tuners are usually integrated into a television set, VCR, digital video recorder (DVR), or set-top box which provides audio/video output connectors of various types.
TiVo digital video recorders encompass a number of digital video recorder (DVR) models that TiVo Corporation designed. Features may vary, but a common feature is that all of the units listed here require TiVo service and use its operating system.
Mobile television is television watched on a small handheld or mobile device, typically developed for that purpose. It includes service delivered via mobile phone networks, received free-to-air via terrestrial television stations, or via satellite broadcast. Regular broadcast standards or special mobile TV transmission formats can be used. Additional features include downloading TV programs and podcasts from the Internet and storing programming for later viewing.
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 Corporation. 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.
This is a comparison of digital video recorder (DVR), also known as personal video recorder (PVR), software packages. Note: this is may be considered a comparison of DVB software, not all listed packages have recording capabilities.
HDHomeRun is a network-attached digital television tuner box, produced by the company SiliconDust USA, Inc.
GB-PVR was a PVR application, running on Microsoft Windows, whose main function was scheduling TV recordings and playing back live TV. GB-PVR is no longer under active development and has been superseded by NextPVR, also known as nPVR.
PlayTV is an add-on unit for the PlayStation 3 video game console that allows the PS3 to act as an HDTV or DTV receiver, as well as a digital video recorder. It was used for recording television programmes to the hard drive for later viewing. A twin-channel DVB-T turner was released in some territories with active DVB-T broadcasts.
A free-to-air or FTA Receiver is a satellite television receiver designed to receive unencrypted broadcasts. Modern decoders are typically compliant with the MPEG-2/DVB-S and more recently the MPEG-4/DVB-S2 standard for digital television, while older FTA receivers relied on analog satellite transmissions which have declined rapidly in recent years.
SAT>IP specifies an IP-based client–server communication protocol for a TV gateway in which SAT>IP servers, connected to one or more DVB broadcast sources, send the program selected and requested by an SAT>IP client over an IP-based local area network in either unicast for the one requesting client or multicast in one datastream for several SAT>IP clients.
DVB Dream is a proprietary software for watching & recording of digital TV & radio with help of a digital TV tuner card. It supports the standards DVB-S (satellite), DVB-C (cable), DVB-T (terrestrial), ISDB-T, ISDB-S and ATSC.
