MHEG
MHEG-5, or ISO/IEC 13522–5, is part of a set of international standards relating to the presentation of multimedia information, standardised by the Multimedia and Hypermedia Experts Group (MHEG). It is most commonly used as a language to describe interactive television services. Characteristics MHEG-5 is a licence-free and public standard for interactive TV middleware that is used both to send and receive interactive TV signals.

It is used by Freeview and Freesat in the UK, Freeview in New Zealand, TVB in Hong Kong, Freeview (Australia), Freeview in Australia, Saorview in Ireland and has been specified in South Africa. Recent work by the DTG in the UK has led to the development of the MHEG-5 Interaction Channel (MHEG-IC), which enables an extension of broadcast interactive services to be delivered via an IP connection. The principles behind the MHEG-IC are to provide a seamless viewer experience of broa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hybrid Broadcast Broadband TV
Hybrid Broadcast Broadband TV (HbbTV) is both an industry standard ( European Telecommunications Standards Institute (ETSI) TS 102 796) and promotional initiative for hybrid digital television to harmonise the broadcast, Internet Protocol Television (IPTV), and broadband delivery of entertainment to the end consumer through connected TVs (smart TVs) and set-top boxes.

Multimedia Home Platform
Multimedia Home Platform (DVB-MHP) is an open middleware system standard designed by the DVB project for interactive digital television. The MHP enables the reception and execution of interactive, Java-based applications on a TV set. Interactive TV applications can be delivered over the broadcast channel, together with audio and video streams. These applications can be for example information services, games, interactive voting, e-mail, SMS or shopping. MHP applications can use an additional return channel that has to support IP. 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.

An interactive video-on-demand (VOD) television service was proposed in 1986 in Japan, where there were plans to develop an "Integrated Network System" service. It was intended to include vario ...

Viewer Access Satellite Television
The Viewer Access Satellite Television service, or VAST, is a satellite television platform in Australia, providing digital television and radio services to remote and rural areas, as well as viewers in terrestrial black spots. The service uses the Optus C1 and Optus D3 satellites. It is partly funded by the Australian Government and managed through a joint-venture between Southern Cross Media and Imparja Television. It is an even more restricted free-to-view replacement for Optus Aurora providing channels which have been absent (such as a Network Ten affiliate and digital only secondary and HD network channels) on the remote service until now. The platform uses only H.264 video encoding and 8PSK, which allows for more lower bit rate channels on the limited transponder space that's available. The EPG uses an MHEG-5 guide instead of the usual more compatible DVB EIT. History On 10 January 2010, the Australian Government announced a new satellite service to deliver digital te ...

Profile (engineering)
In standardization, a profile is a subset internal to a specification. Aspects of a complex technical specification may necessarily have more than one interpretation, and there are probably many optional features. These aspects constitute a profile of the standard. Two implementations engineered from the same description may not interoperate due to having a different profile of the standard. Vendors can even ignore features that they view as unimportant, yet prevail in the long run. The use of profiles in these ways can force one interpretation, or create de facto standards from official standards. Engineers can design or procure by using a profile to ensure interoperability. For example, the International Standard Profile, ISP, is used by the ISO in their ISO ISP series of standards; in the context of OSI networking, Britain uses the UK-GOSIP profile and the US uses US- GOSIP; there are also various mobile profiles adopted by the W3C for web standards.
