4DTV
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 II and digital DCII satellite channels.
4DTV technology was originally developed in 1997 (the same year that DigiCipher was developed) by General Instrument/NextLevel and Motorola, now a division of ARRIS. The 4DTV format is contemporary to the DVB-based digital television broadcast standard but its completion came before that of DVB and thus it is similar but incompatible with the DVB standard. The DigiCipher 2 encryption system is used in digital channels much like the VideoCipher and VideoCipher II systems were used for analog encrypted transmissions. By the time when analogue VideoCipher II channels are switched to digital, all of the remaining VCII-encrypted channels (excluding in the clear) are transitioned to DigiCipher II on all satellites that carries either in the clear or VideoCipher II/II+/RS-encrypted channels. On December 31, 2010, Motorola abandoned support for 4DTV after 13 years when it was developed. This made all of the receivers to redirect to AMC-18 (also known as W5/X4 on the 4DTV system) instead of its other satellites that carried analog/VCII channels.
On August 24, 2016, at 9:18 AM EST, Headend In The Sky (the provider for 4DTV/DigiCipher II programming) transitioned to DVB-S2 (MPEG-2/256 QAM), meaning that support for 4DTV ended on that date.[1]
4DTV is designed for C-band/Ku-band based satellite dishes (both TVRO/direct-broadcast) in conjunction with the DigiCipher II system (for digital standard definition/high definition signals) and the VideoCipher II system (for analog signals). It is also used on Canada's Shaw Direct (previously known as Star Choice) until 2017 when standard definition broadcasting ended in favour of HDTV exclusively, making the receivers obsolete.
4DTV receivers were designed to receive analog NTSC (except the DSR-905) in the clear or VideoCipherII channels and feeds, as well as digital Digicipher 2 channels as a TVRO satellite system on both C and Ku band-powered satellite dishes.
Four models are available, either new or refurbished:
The HDD-200 is a peripheral for 4DTV, it is used to access high definition channels via the Mult-Media Access Port. This peripheral is no longer in production.
In the United States, National Programming Service, LLC (NPS) was the primary provider of subscription programming to 4DTV and C band/Ku band users. They ceased operations as of December 26, 2010 after making a controversial attempt of converting all of their customers over to Dish Network which failed. The largest providers are now Satellite Receivers, Ltd. (SRL) and Skyvision who sell programming from the Headend In The Sky (HITS) service by Comcast and will continue to do so in 2011 and beyond. The HITS services use the Comcast Subscription Authorization Center (SAC) for the channels being broadcast on the AMC 18 satellite located at 105 degrees West (W5 or X4 tile on 4DTV). In Canada, Dr. Sat is now the primary provider for HITS subscription services offered on C-Band after Satellite Communications Source ceased operations.
