Digital Video Broadcasting (Project) - (DVB) - DVB is a major European based consortium regarding the transmission of digital television. DVB systems distribute data using a variety of approaches including by satellite: DVB-S, DVB-S2 and DVB-SH; also DVB-SMATV for distribution via SMATV; cable (DVB-C); terrestrial television (DVB-T) and terrestrial television for handhelds (DVB-H); also via microwave using DTT (DVB-MT), the MMDS (DVB-MC), and/or MVDS standards (DVB-MS). Also DVB-DATA, with return channels (DVB-RC) for several media (DECT, GSM, PSTN/ISDN, satellite etc.), protocols (DVB-IPI: Internet Protocol; DVB-NPI: network protocol independent, (DVB-CA, (DVB-CSA), a physical Common Interface (DVB-CI) for accessing scrambled content and DVB-CPCM, a content protection and copy management system for received content. DVB also supports older technologies such as teletext (DVB-TXT) and vertical blanking interval data (DVB-VBI). (More advanced alternatives like DVB-SUB for sub-titling are available.)

Digital Video Broadcasting-Multimedia Home Platform - (DVB-MHP) - This is a specification by the DVB. It's a software specification for implementation in set-top boxes, integrated digital TV receivers, multimedia PCs and other devices. This MHP specification can connect broadcast mediums such as Internet and television, through these devices and their associated peripherals. http://en.wikipedia.org/wiki/DVB-MHP

DVB-S - DVB-S is the original Digital Video Broadcasting forward error coding and modulation standard for satellite television, and dates back to 1995. It's used by satellites serving every continent of the world. DVB-S is used in both MCPC and SCPC modes for broadcast network feeds, as well as for direct broadcast satellite services like Sky TV (UK), Astra in Europe, Dish Network and Globecast in the U.S. and Star Choice and Bell ExpressVu in Canada. The transport stream delivered by DVB-S is mandated as MPEG-2. (This is a 2006 definition.)

DVB-S2 -
Digital Video Broadcasting - Satellite - Second Generation -
DVB-S2 is an improved and updated specification of the DVB-S (Digital Video Broadcasting-Satellite) standard. It was developed in 2003 and ratified by ETSI in March 2005. DVB-S2 will probably be used for all future new European digital satellite multiplexes, and satellite receivers will be equipped to decode both DVB-S and DVB-S2.

The most significant use of the
DVB-S2 standard is for the distribution of HDTV.

If the typical lifetime of a Direct to Home set-top box is about 5 years, with most lasting 7 years or more, it's possible that the conversion process to DVB-S2 could take about 10 years. (Reference)
