At present, the two-way net in various places changes as yet not to be accomplished comprehensively, and unidirectional (CA) and two-way (CA) also deposits, and for adapting to various STBs, the realization of television MMS also is divided into unidirectional and two-way dual mode.For unidirectional multimedia message, notification unit is broadcast at the full range point, and load cell is broadcast at fixing frequency; For two-way multimedia message, notification unit full range point is broadcast, and MMS content is through two-way return path inquiry.And middleware can certainly be selected the multimedia message receive mode according to actual environment, and the mode of broadcasting is transparent for the user.
3, based on the wheel Broadcast Control system of dynamic load
For adapting to the growing MMS broadcast demand of quantity, each department all are provided with many and broadcast server, and system needs balancedly to broadcast task for each server-assignment according to broadcasting live telecast.
The calculating of broadcasting ability not only will be according to the server current state, depends on more to wait for and broadcast queue length and server performance, and at this, clustered software, hardware load-balancing device are all inapplicable.For this reason; System adopts the control strategy of broadcasting that is similar to dynamic load leveling; Each department Duo Tai broadcasts server and logically constitutes cluster; Broadcast server for every and detect service and two-way multimedia message service report server state and block queue length to multimedia message in real time, multimedia message detects service and two-way multimedia message service according to the ability of the broadcasting valuation of writing down in the present load of each station server and the database, dynamically assembles with distributing and differently big or small broadcasts packet to respectively broadcasting server; The maximization wheel is broadcast number of times, improves the rate of sending to.
4, remote controller Chinese character input
Though Chinese character entering technique has been used for many years, on STB, still there be not ripe the application.This project adopts remote controller input Chinese character; At the multimedia message page; When the user imported MMS content, the function of numerical key 0-9, affirmation and function keys such as shifting bond(s), F5-F9 on the remote controller was all with specifically defined, and functions of functional keys, phonetic input and Chinese character select prompting to show at television image.This function realizes through middleware terminal Chinese character base and Chinese character input module.
5, wireless peripheral Chinese character input
For the TV user of uncomfortable operating remote controller, system supports the writing pen input mode.Writing pen need support wireless signal to send, and STB needs built-in wireless signal receiving system, the Chinese character encoding storehouse that the two all need be followed the Wifi agreement and adopt unified version.Middleware is caught the wireless message of input, and identifies Chinese character, shows for alternately the content input page of multimedia message assembly again.
Handwriting pad also can be integrated on the set-top box remote controller.
6, multifactor user profile coupling anticipation
Television MMS is broadcast based on the addressing of CA card number, but does not comprise this in industry customer's the user profile, and this just needs between family's TV user and industry customer's customer group, to set up corresponding relation through total field.
