A kind of digital video broadcast player

Technical field

The utility model relates to a kind of digital video broadcast player, based on the digital video broadcast player of intelligent mobile phone system.

Background technology

Along with iOS system, Android system in extensive uses such as smart mobile phone, multimedia recreation, networks, because it is simple and easy to usefulness, gorgeous UI, power, unlimited software, obtained the development of advancing by leaps and bounds, let us has been experienced the Internet, information industry, computer, multimedia consumingly to the tremendous influence power of people life.

Set-top box (the English name full name is SetTopBox, is called for short STB) refers to strengthen or expand a kind of information equipment of functions of television set.It allows the user on existing simulated television, watches, listens to TV, broadcast program, carries out the consumption industry electronic product of interactive digital amusement, education and commercialization activity.Since people usually it is placed on television set above, so be called as set-top box or top setting box.Set-top box has analog-and digital-dividing.The said set-top box of people generally refers to top box of digital machine now.

It can provide high-quality to TV user, and band enriches the television program of function.

Digital television broadcasting has a lot of standards in the world, such as DVB standard (comprising DVB-S, DVB-S2, DVB-C, DVB-C2, DVB-T, DVB-T2, DVB-H, DVB-SMATV, DVB-MS, DVB-MC), ATSC standard, ISDB standard, DTMB standard etc.

The fashionable world of iOS system applies.Apple iOS is the handheld equipment operating system by Apple's exploitation.Apple is that design is used to iPhone early than announcing this system in the Macworld conference on January 9th, 2007 at first, and cover was used on the apple products such as iPod touch, iPad and Apple TV successively afterwards.IOS is the same with the Mac OS X operating system of apple, and therefore it belong to the commercial operation system of class Unix equally also take Darwin as the basis.Originally this system is called iPhone OS, until announce to be renamed as iOS in the WWDC conference on June 7 in 2010.

The Android system be Google exploitation based on the Linux platform, increase income, operation system of smart phone.Android comprises operating system, middleware and application program, because open source, Android can be transplanted on the different hardware platforms.OHA (Open Handset Alliance, open mobile phone alliance) is for Google and 33 companies unite a tissue of setting up for the development of Android mobile platform system.From the angle of macroscopic view, Android is the software systems of an opening, and it has comprised numerous source codes.

Digital television broadcasting has a lot of standards in the world.According to the Global Regional difference four mainstream standard are arranged:

1, the DVB standard is the Digital Television Open Standard of international recognition, and DVB is the abbreviation of digital video broadcasting Digital Video Broadcasting.The DVB project be one by the industrial organization of more than 300 member compositions.DVB is the Digital Television Open Standard DVB standard by a series of international recognitions of DVB project maintenance, and it provides a cover digital television system standard complete, that be applicable to different media.The DVB digital broadcasting transmission system has utilized all general television broadcasting transmitting media that comprise satellite, wired, ground, SMATV, MNDSD.They are the DVB standard of correspondence respectively: DVB-S, DVB-S2, DVB-C, DVB-C2, DVB-T, DVB-T2, DVB-H, DVB-SMATV, DVB-MS and DVB-MC.

2, ATSC is the Digital Television national standard of the U.S., and the English full name of ATSC is Advanced Television Systems Committee (U.S. advanced television management consultant committee).This committee formally passes through ATSC Digital Television national standard September 15 nineteen ninety-five.ATSC information source coding processed adopts MPEG-2 video compression and AC-3 audio compression; Chnnel coding adopts the VSB modulation, provides two kinds of patterns: terrestrial broadcasting pattern (8VSB) and High Data Rate pattern (16VSB).

3, ISDB is the digit broadcasting system standard of DIBEG (the Digital Broadcasting Experts Group digital broadcasting expert group) formulation of Japan, it utilizes a kind of standardized multiplexing scheme to send various different types of signals at a common transmission channel, and multiplexing signal also can send by various transmission channel simultaneously.ISDB has flexibility, autgmentability, the characteristics such as intercommunity, neatly integrated TV and other data service with sending Polymera.

4, DTMB, full name Digital Television Terrestrial Multimedia Broadcasting.The Altera Stratix II FPGA power-assisted DTV of Tsing-Hua University develops DTMB.China set up Digital Television research and development and industrialization and set up national digital TV leading group in 1999, clearly declared the autonomous technical standard of formulating.For the specific standards of China's digital television application, released China digital TV ground standard DTMB in 2006.

But as in Android system or iOS system, the Applied Digital television broadcasting but or blank on the linux system.
