Multimedia Home Platform
Multimedia Home Platform (DVB-MHP) is an open
Deployment
In May 2010 the largest deployments DVB-MHP are in Italy (DVB-T), Korea (DVB-S), Belgium (DVB-C) and Poland (DVB-S) with trials or small deployments in Germany, Spain, Austria, Colombia, Uruguay and Australia.
MHP service was also offered in Finland by Finnish Broadcasting Corporation (Yleisradio), but the service was shut down at the end of 2007 after technical failure. The shutdown wasn't ever officially announced. Ultimately the reason for the shutdown was that MHP never gained "critical mass".[1] The main reasons for its lack of success in Finland were: 1) 50% of the Finnish households use the terrestrial network, where broadcasting of MHP applications can be really expensive, 2) TV broadcasters never told TV viewers about the MHP services—because the digitalization of the TV networks got extremely negative publicity in Finnish media, the broadcasters didn't want to upset their customers further if they had bought new expensive STBs which weren't capable of playing MHP apps, and 3) there were only a few MHP set-top boxes in the market—because Finland is such a small market, big manufacturers weren't interested in developing new MHP boxes just for Finland. MHP-capable STBs are no longer available in Finland.
The U.S. cable industry has specified its own middleware system referred as OCAP, which is largely based on MHP.

Technology
The MHP specifies an extensive application execution environment for digital interactive TV, independent of the underlying, vendor-specific, hardware and software. This execution environment is based on the use of a
The MHP is just a part of a family of specifications, which all base on the Globally Executable MHP (GEM)-Standard, which was defined to allow the worldwide adoption of MHP.
