Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of customization hotel digital television front-end system, hotel is set by media resource system and manages channel by oneself, realize the Personalized service in hotel, and the big net signal of broadcasting and TV is delivered directly to hotel's Set Top Box, greatly reduce decoding, solve the I&M of the equipment such as mediation coding, simultaneously can realize hotel by a Set Top Box and manage freely switching of channel and the big net TV signal of broadcasting and TV by oneself, meet different user's requests.
For solving above-mentioned technical problem, the present invention relates to a kind of customization hotel digital television front-end system, including big network data television signal system and Hospitality management system, described Hospitality management system generates hotel and manages signal by oneself, and described hotel manages signal by oneself and includes managing advertising signal by oneself and managing channel signals by oneself；Hospitality management system includes ad system operating side and media asset management system operating side, advertisement scheduling system (MIS) is operated by described ad system operating side, advertising signal input advertisement broadcast system is managed in generation by oneself, and advertisement broadcast system is by IP plug-flow signal transmission to IPQAM；Media asset management system (CMS) is operated by described media asset management system operating side, produces to manage channel signals input program plug-flow system (VSS) by oneself, and program plug-flow system is by IP plug-flow signal transmission to IPQAM；Described signal of managing by oneself is transmitted to blender by IPQAM, and is mixed at blender with big network data TV signal, then inputs same Set Top Box (STB), and television set receives play signal from Set Top Box.
In preferred version, customizing hotel's digital television front-end system and also include satellite reception performance system, the satellite program signals received is managed signal through QAM input mixer by oneself be mixed with described big network data signal and hotel, then inputs same Set Top Box.
In preferred version, the operation of described ad system operating side and media asset management system operating side is undertaken by logging in browser.
In preferred version, described play signal is picture, word, flash file, video or webpage.
In preferred version, described Set Top Box acquiescence manages channel by oneself as dominant frequency point, issues EPG data at dominant frequency point, and Set Top Box searches the program of big network data television signal system frequency by the EPG data (JSON file) of dominant frequency point；Described EPG data includes Chinese display and English display.
In preferred version, described EPG data exports each STB terminal in hotel by plug-flow system in the way of data carousel.
In preferred version, described in manage advertising signal by oneself and include start-up picture, start application, hotel service system, EPG advertisement and manage channel corner advertisements by oneself.
In preferred version, described advertisement scheduling system includes ad material sorting module and advertisement editor module, described ad material sorting module is responsible for the importing of advertisement, amendment and deletion, described advertisement editor module is responsible for Advertisement arrangement editor, ad review and advertisement packing encapsulation, described advertisement scheduling system by packing encapsulation after data stream transmitting to advertisement broadcast system, advertisement broadcast system exports IP multicast in the way of carousel and flow to IPQAM after receiving data stream.
In preferred version, described manage channel signals by oneself playing flow path be: described media asset management system uploaded videos program is to program plug-flow system, then described media asset management System build playlist is sent to program plug-flow system, then described media asset management system sends broadcasting/halt instruction to program plug-flow system, and program plug-flow system is according to playlist carousel video；Importing EPG information to media asset management system, media asset management system is pushed to program plug-flow system EPG information, and program plug-flow system broadcasts EPG information.
System takes into full account broadcast safety problem when design, systemic-function decoupling necessary with conversational traffic, does not affect the broadcast in hotel of the big net ordinary numbers TV programme in any case；Program number and video modulation are set at Lacal Head End, program number and frequency are carried out unified planning, it is ensured that do not conflict with the program number in CHINA RFTCOM Co Ltd and frequency, it is ensured that program safe broadcast.
The invention have the benefit that realizing hotel by a Set Top Box manages freely switching of channel and big net TV signal by oneself, user can select channel to play by a remote controller, has saved hotel's cost, simultaneously convenient for users to use；Carry out channel customization and the advertisement customization of personalization for Official hotel, greatly facilitate special service and the human nature service in hotel；EPG data exports each STB terminal in hotel by plug-flow system in the way of data carousel, and when big net EPG adjusts, it is unaffected that hotel system customizes EPG；Big net signal can include multiple channel signals, all directly pushes to hotel's Set Top Box, and terminal maintenance is done by broadcasting and TV, and hotel need not build the coding/decoding apparatus for big net signal, greatly reduces the installation of equipment and the expense of maintenance.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.It should be noted that accompanying drawing is merely illustrative, do not draw according to strict ratio, and be wherein likely to promising describe convenient and carry out partial enlargement, reduce, conventional partial structure is also likely to have necessarily default.
Referring to Fig. 1, the present invention relates to a kind of customization hotel digital television front-end system, including big network data television signal system and Hospitality management system, it is preferable that also include satellite program signals in scheme, the satellite antenna installed from hotel receives.
