Shallow the technology that talks about digital annunciate, IPTV and mobile TV i

Using Internet pilot system can be the is based on IPTV frame that narrates before the article. The platform that is based on Internet has natural double tropism, whole network can manage remotely and control, realize real significance to go up thereby " much channel " , achieve pointing to calm time, appoint a place, use appoint means to broadcast the goal that assigns content. This spreads all over the network of much trade to, have very real sense, can accomplish true " narrow sow " . For instance: Be in when hospital, station, office building same when time needs to use different content to broadcast, with respect to need the setting differs " channel " , this is very handy to be based on the platform of Internet, and network of mobile to TV, need of so much channel compares need augment much resource, difficulty increases unexpectedly. And, even if was to add many channel, how to come true to broadcast appointed channel in appointed place? Player or how does machine top box realize long-range control, below one-way beamed mode, bad still to solve.

If only net profit uses Internet,the platform that is based on Internet transmits a respect in media, inferior position is in in bandwidth respect, even if with present broadband, be being returned compared with TV network is far apart.

Very apparent, an effective digital annunciate network needs to combine both advantage. Specific and character, put in two kinds of fundamental pattern, one is in transmission level, one is information is changed to transmit a respect in this locality. The first kind of circumstance, what use Internet namely is two-way can accuse a mechanism, form much channel (group) management, in the meantime, data is distributed use data broadcast way to realize high speed to transmit. This kind uses platform of annunciate of data beamed number is one is mixed neatly truly efficient platform. The 2nd kind of circumstance, still give priority to with the program of mobile TV, build the highway that this locality changes through IPTV compose, the information this locality (the information that is like him bank, him traffic information) overlay is in mobile TV advocate on video, perhaps undertake partition shows, build component from another angle numerous the much channel idea that turn. Use about what digital annunciate data distributes a passageway, it is to apply to mobile TV not only, cable television and satellitic TV network can offer data of this kind of high-speed to distribute.
