For the AI software: AlphaStar (software)
AlphaStar Digital Television was a direct-to-home satellite broadcasting service for the United States market developed by Canadian firm Tee-Comm Electronics. It was the first direct-to-home satellite broadcasting service in the United States to use the internationally accepted DVB-S broadcasting standard and used 39" satellite dish receivers. [1] Its service launched in July 1996, but was discontinued completely by September 1997 with 40,000 subscribers as the company went through bankruptcy proceedings. [2] The American assets of AlphaStar was used under the auspices of the Champion Telecom Platform which used to own the AlphaStar brand. [3] AlphaStar would also have alleviated a shortage of Canadian satellite capacity by using foreign (US) satellite capacity to fill Canadian needs—indeed this was a requirement for the Canadian company to obtain its license from Canada to commence broadcasting. Tee-Comm, the parent company of AlphaStar had originally co-founded the partnership that created ExpressVu (later Bell Satellite TV) as technology supplier but later divested all interest in ExpressVu.
In March 1995, AlphaStar leases 12 transponders on satellite Telstar 402R for a capacity of 110 video and 20 audio channels.
On 1 July 1996, AlphaStar service launches using 12 transponders on satellite Telstar 402R at 89°W in the Ku-band.
In 1996, AlphaStar obtained $102 million in a debt offering, but analysts claim it could have claimed double that sum.
In late 1996, AlphaStar's corporate parent Tee-Comm, owned by Alvin Bahnman, divested itself from the partnership it co-founded that created the Canadian ExpressVu DBS service, known today as Bell Satellite TV. As a result, ExpressVu obtained equipment and technology from EchoStar.
In 1997, AlphaStar was in the process of transitioning to the newly launched Telstar 5 satellite with the capacity for 200 video channels and 40 audio channels.
On 3 March 1997, AlphaStar announced AlphaStar Canada service with 75 channels of service (in reality only 35 were full-time video). [4] The Canadian service never launched as the company went bankrupt and ceased broadcasting operations by September of that same year.
On 27 May 1997, the company initiated bankruptcy proceedings.
In August 1997 the operator of the Telstar 5 satellite, then named Loral Skynet, terminated its contract with AlphaStar after asking to be released from the contract earlier that year.
At 03:00 on 7 August 1997 the company ceased broadcasting operations, stranding 40,000 subscribers. Competitors quickly offered trade-in deals.
In 1998, an Egyptian tycoon named Mahmoud Wahba was reported by the Investor's Business Daily to have bought the assets of the failed AlphaStar for $4.65 million.
Champion Telecom Platform company was launched using the facilities of AlphaStar, providing uplink facilities as well as direct-to-home satellite internet broadband services. [5]
On 19 September 2003, the Telstar 402R satellite used by AlphaStar from 1996-1997, renamed Telstar 4, experienced a circuit failure in its primary power bus and was declared a total loss.
Originally broadcasting on Telstar 402R in the Ku-band, AlphaStar was in the process of transitioning to the newly launched Telstar 5 satellite and 120 channel service when the company initiated bankruptcy proceedings.
A satellite uplink facility in Oxford, Connecticut was used to uplink the AlphaStar service. The facility was one of the assets of the company now owned by Champion Telecom Platform. The communications teleport was originally built for the United States government for the Strategic Defense Initiative, according to Champion, and can allegedly withstand nuclear attack. Another uplink facility was in Milton, Ontario, Canada.
Dish receiving equipment for AlphaStar were large, 36-39" elliptical reflectors designed to receive medium-powered, linear-polarized Ku-band signals in the Fixed Service Satellite band in the area of 11.7 GHz from Telstar 402 and, eventually Telstar 5 (now named Galaxy 25). By comparison, direct competitors DirecTV and Dish Network offered 18" dishes. The AlphaStar dishes were originally sold by Canadian firm Tee-Comm, an electronics outfit and builder of satellite dishes that was the parent company of AlphaStar.
Set-top boxes for AlphaStar were manufactured by Samsung and Hyundai. The service used DVB-S signalling and MPEG-2 video compression called Compression NetWORKS developed by a firm named TV/COM International. It was the first United States direct-to-home broadcaster to use what became known as DVB-S. [6] While pricey and inconvenient to use these receivers can be used to receive unencrypted satellite transmissions known as FTA.
As AlphaStar liquidated its inventory the expensive AlphaStar dishes were resold to customers who wished to receive ethnic programming. An Egyptian broadcasting service which formerly broadcast several channels on AlphaStar offered assistance in refitting AlphaStar systems to receive their channels from another satellite, Intelsat Americas 5, which, ironically, was the new name of the very same Telstar 5 satellite that AlphaStar was in the process of migrating to. Though exceedingly rare, refitted AlphaStar dishes can still be found on rooftops in larger urban ethnic communities and their large size offers great signal quality.
The Ku band is the portion of the electromagnetic spectrum in the microwave range of frequencies from 12 to 18 gigahertz (GHz). The symbol is short for "K-under", because it is the lower part of the original NATO K band, which was split into three bands because of the presence of the atmospheric water vapor resonance peak at 22.24 GHz, (1.35 cm) which made the center unusable for long range transmission. In radar applications, it ranges from 12 to 18 GHz according to the formal definition of radar frequency band nomenclature in IEEE Standard 521–2002.
Television receive-only (TVRO) is a term used chiefly in North America, South America to refer to the reception of satellite television from FSS-type satellites, generally on C-band analog; free-to-air and unconnected to a commercial DBS provider. TVRO was the main means of consumer satellite reception in the United States and Canada until the mid-1990s with the arrival of direct-broadcast satellite television services such as PrimeStar, USSB, Bell Satellite TV, DirecTV, Dish Network, Sky TV that transmit Ku signals. While these services are at least theoretically based on open standards, the majority of services are encrypted and require proprietary decoder hardware. TVRO systems relied on feeds being transmitted unencrypted and using open standards, which heavily contrasts to DBS systems in the region.
4DTV is a proprietary broadcasting standard and technology for digital cable broadcasting and C-band/Ku-band satellite dishes from Motorola, using General Instrument's DigiCipher II for encryption. It can tune in both analog VideoCipher 2 and digital DCII satellite channels.
Multichannel multipoint distribution service (MMDS), formerly known as broadband radio service (BRS) and also known as wireless cable, is a wireless telecommunications technology, used for general-purpose broadband networking or, more commonly, as an alternative method of cable television programming reception.
Digital Video Broadcasting – Satellite (DVB-S) is the original DVB standard for satellite television and dates from 1995, in its first release, while development lasted from 1993 to 1997. The first commercial applications were by Star TV in Asia and Galaxy in Australia, enabling digitally broadcast, satellite-delivered television to the public. DVB-S was the first DVB standard for satellite, defining the framing structure, channel coding and modulation for 11/12 GHz satellite services.
PrimeStar was a U.S. direct broadcast satellite broadcasting company formed in 1991 by a consortium of cable television system operators and GE Americom, the satellite arm of General Electric, collectively referred to as the PrimeStar Partners. PrimeStar was the first medium-powered DBS system in the United States but slowly declined in popularity with the arrival of DirecTV in 1994 and Dish Network in 1996.
Satellite Internet access or Satellite Broadband is Internet access provided through communication satellites. This technology enables users to access the Internet regardless of their geographical location. Modern consumer grade satellite Internet service is typically provided to individual users through geostationary satellites that can offer relatively high data speeds, with newer satellites using Ku band to achieve downstream data speeds up to 506 Mbit/s. In addition, new satellite internet constellations are being developed in low-earth orbit to enable low-latency internet access from space.
Free-to-air (FTA) services are television (TV) and radio services broadcast in unencrypted form, allowing any person with the appropriate receiving equipment to receive the signal and view or listen to the content without requiring a subscription, other ongoing cost, or one-off fee. In the traditional sense, this is carried on terrestrial radio signals and received with an antenna.
Bell Satellite TV is the division of BCE Inc. that provides satellite television service across Canada. It launched on September 10, 1997. As of April 2017, Bell Satellite TV provides over 700 channels to over 1 million subscribers. Its major competitors include satellite service Shaw Direct, as well as various cable and communications companies across Canada.
Digital Video Broadcasting - Satellite - Second Generation (DVB-S2) is a digital television broadcast standard that has been designed as a successor for the popular DVB-S system. It was developed in 2003 by the Digital Video Broadcasting Project, an international industry consortium, and ratified by ETSI in March 2005. The standard is based on, and improves upon DVB-S and the electronic news-gathering system, used by mobile units for sending sounds and images from remote locations worldwide back to their home television stations.
Telesat, formerly Telesat Canada, is a Canadian satellite communications company founded on May 2, 1969. The company is headquartered in Ottawa.
The PBS Satellite Service consists of feeds relayed from PBS by satellite to public television stations throughout the United States. The service was launched in September 1978. The service provides a mixed variety of programming selected from PBS's regular network services. In the X/XP years a satellite feed was multicast by some PBS member stations on an over-the-air DTV sub-channel along with their regular programming, or during overnight hours on their main channel to provide a second opportunity for viewers to watch or record primetime programming.
Tee-Comm Electronics was a Canadian satellite television equipment manufacturer that founded the AlphaStar and co-founded the Bell Satellite TV satellite direct-to-home television services.
Satellite television is a service that delivers television programming to viewers by relaying it from a communications satellite orbiting the Earth directly to the viewer's location. The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block downconverter.
DVB-RCS is an acronym for Digital Video Broadcasting - Return Channel via Satellite or. It is a specification for an interactive on-demand multimedia satellite communication system formulated in 1999 by the DVB consortium.
Television is the most popular medium in Russia, with 74% of the population watching national television channels routinely and 59% routinely watching regional channels. There are 3300 television channels in total. Before going digital television, 3 channels have a nationwide outreach : Channel One, Russia-1 and NTV.
Currently, there are two primary satellite television providers of subscription based service available to United States consumers: DirecTV and Dish Network, which have 21 and 10 million subscribers respectively.
Satellite television varies in the different regions around the world.
