DVB-S2 is designed for broadcast services including standard and HDTV, interactive services including Internet access, and (professional) data content distribution. The development of DVB-S2 coincided with the introduction of HDTV and H.264 (MPEG-4 AVC) video codecs. Two new key features that were added compared to the DVB-S standard are:
In 2016, the GBS program manager developed the GBS Phase-IV capability that included an upgraded Transportable Ground Receive Suite (TGRS), development of Suitcase and Rucksack Portable Receive Suites (SPRS and RPRS), and integration of the new Digital Video Broadcasting – Satellite – Second Generation (DVB-S2) waveform that should provide ...
DirecTV is now using a modified version of DVB-S2, the latest version of the DVB-S protocol, for HDTV services off the SPACEWAY-1, SPACEWAY-2, DirecTV-10 and DirecTV-11 [2] satellites; however, huge numbers of DSS encoded channels still remain. The ACM modulation scheme used by DirecTV prevents regular DVB-S2 demodulators from receiving the ...
The MPEG transport stream delivered by DVB-S is mandated as MPEG-2. DVB-C stands for Digital Video Broadcasting - Cable and it is the DVB European consortium standard for the broadcast transmission of digital television over cable. This system transmits an MPEG-2 family digital audio/video stream, using a QAM modulation with channel coding.
Cable started broadcasting digital in 2001. Most cable companies switched off analogue in 2021. Satellite broadcasting switched to the digital standard in 1996 and to DVB-S2 around 2010. The last DVB-S channels were shut down in 2016. DVB-H was only available for a brief period between 2008 and 2011 in the bigger cities.
The DVB-S2 selection committee made decoder complexity estimates for the turbo code proposals using a much less efficient serial decoder architecture rather than a parallel decoder architecture. This forced the turbo code proposals to use frame sizes on the order of one half the frame size of the LDPC proposals. [citation needed]
DVB-S2X is an extension of DVB-S2 satellite digital broadcasting standard. It was standardized by DVB Project [ 1 ] in March 2014 as an optional extension of DVB-S2 standard. [ 2 ] It became an ETSI standard.
Other standards, such as digital multimedia broadcasting (DMB) and digital video broadcasting - handheld (DVB-H), have been devised to allow handheld devices such as mobile phones to receive TV signals. Another way is Internet Protocol television (IPTV), which is the delivery of TV over a computer network.
