The demand that market is merged for three screens is also increasingly stronger, it by allow IPTV customer volume and Service Market have faster increasing
It is long, it is that mobile flow medium, particularly IPTV break through the good trial of current development bottleneck.
So-called three screen, refers to computer screen, TV screen and Mobile phone screen, three current screens fusion, is considered from terminal point, real
Content interconnects between three existing Mobile phone screen, computer screen, TV screen screens.Certainly, this interconnect not only refers to
Three screens play identical content, but according to three screen features, existing unification is again variant, is formed between three screens
Good video feeds transmit complementation and service is unified, so as to promote mutual value promotion.
But three-screen-interaction is realized, first have to realize the different media storages between IPTV, MVS and WebTV three
And media services, because the network of tri- kinds of service accesses of IPTV, MVS and WebTV is different, the terminal type and access way of access
And the appearance form of business also differs, therefore multi-service convergence platform must be completed to the automatic of multi-access terminal and network

1 html file, src fields therein point to index file；
1 media catalog, wherein deposit side by side for 1 form pointing to TS segmental files as m3u8 (audio frequency and video) or
M3u (pure audio) index file；
1 TS catalogue, multiple * .ts segmental files are deposited side by side in TS catalogues；
Deposited side by side in each multi code Rate of Chinese character VOD content：
1 html file, wherein src fields point to master index file；
1 media catalog, wherein deposit side by side the index file for pointing to each code check 1 m3u8 (audio frequency and video) or
M3u (pure audio) master index file；
Multiple TS catalogues, each TS catalogues deposit side by side 1 m3u8 (audio frequency and video) for pointing to TS segmental files or
M3u (pure audio) index file；
