The Application Research Of Mobile Phone Television Based On CDMB In Intelligent Navigation

Not only the modern science and technology development is changing people's daily life life, is reorganizing the modern medium performance shape and the distributed pattern by the unprecedented speed construction. In past near century time, the television technology has brought the strong message and the entertainment for the humanity. Since similarly, 1980s, the wireless correspondence and the networking have progressed by leaps and bounds impelled the motion network in the application rapid mature, the handset has provided a highly effective convenient communication and the information acquisition way for the people. At present global each big migration operation business has promoted each kind of handset television service based on own 2.5G/3G network parallel connection confluence media technology. Global handset industry popular this kind of view:" The photography was the year before last important matter, music is last year important matter, looked the television is this year important matter". But "looked anytime and anywhere the television", once was people's dream, now along with the handset television service appearance, this dream is turning the reality.On the handset the navigation is refers on the intelligent handset hardware moves the handset navigation software, is the handset navigation initial stage, also is the level which the present mainstream handset navigation locates. On handset in navigation foundation, handset itself communication function organically conformity to navigation software in, thus changes the people to use the electronic map as well as the navigation behavior pattern largely, transits from the sole navigation assistance to omni-directional LBS. But such system has a malpractice, is the navigation line which the system gives is according to the information which saves, but these information also are fixed, for instance some local path information, the supposition such situation, for instance some path is originally opens access, but has just had blocking, trafficked jams stops up specially fiercely, now already is unable to pass through, if obtained time the navigation line with the guidance system, the guidance system could not obtain the information which this path trafficked jams, still thought it was unimpeded, the navigation line still met circuit this road, this has not considered the real-time state of roads information the harm.This article designs the system is, in the tradition guidance system function foundation, through the digital broadcast way handset television service real-time broadcast state of roads information, after the handset receives these information, the real-time state of roads information will integrate to in the traditional guidance system, will enable the guidance system to be able to give the more reasonable navigation line.
