Abstract

The invention provides a method for implementing a set top box architecture based on flash technology. In the method, when a user operates a system interface of a set top box through a remote controller, the set top box defines the code values of the controller as virtual key values and converts the key values into operation which can be recognized by a flash file in one-to-one correspondence in the set top box; at the moment, a flash player resolves the flash file, searches module interfaces in corresponding application programs in the set top box, and calls corresponding functions in modules through the module interfaces so as to accomplish the required operation. By the method for implementing the set top box architecture based on the flash technology, the defect that the interface events and service logic of the traditional set top box are bound together, are difficult to modify and have poor transferability is overcome, development cost is lowered, the system interface and the system functions can be dynamically updated, deployment is convenient, the functions are easy to expand, and the requirements of operators can be well met.

Description

A kind of implementation method based on flash technology set-top box System Framework

[technical field]

The present invention relates to a kind of embedded technology, especially a kind of implementation method based on flash technology set-top box System Framework particularly belongs to the field of set-top technology.

[background technology]

Advocate energetically in current country under the background of the integration of three networks, Digital Television is development rapidly just in China, surges forward abundanter programme content about the various researchs of digital television techniques, higher image sharpness, more the interaction technique of diversification progressively grows up.In order to adapt to the needs of Digital Television, as the digital TV terminal of being close to the users most, set-top box also just develops towards the direction of comprehensive multimedia application platform, and User Interface and application stand in the breach and become the skirmish of this change.Make a general survey of the process of digital TV set-top box product development, a large amount of time that the exploitation of user interface consumes.And because the complicacy and the regionality in China Digital TV market, various operators has proposed various customization requirements, amplifies out different set-top box interface systems.

Wherein the main body of the interface system of set-top box demonstration is the flash file, FLASH is as a cartoon making instrument, its final finished shows with the .SWF file, a SWF file, from the time still is that spatial dimension all is made up of certain structure, the base unit of makeup time order is a frame, and the base unit of forming spatial dimension is a subject.When having used the flash file as the main body of the interface display of whole set-top box, each interface can be considered as different frames, so the user changes the operation at interface, and in fact reaction is for being exactly the different redirect to frame among the flash.And the various tabulations in each interface, therefore combo box, figure, option etc. then are considered to subject, are exactly operation to different objects object among the flash to the operation of menu function.Because the exploitation of general set-top box interface uses the dedicated graphics GUI of system to make up, interface incident and service logic bind together, and when different demand occurring, need remodify code, and compiling downloads in the set-top box.This construction cycle is long, revises loaded down with trivial detailsly, can't satisfy the fast-changing market demand.

[summary of the invention]

The technical problem to be solved in the present invention, be to provide a kind of implementation method based on flash technology set-top box System Framework, having overcome traditional set-top box interface incident and service logic binds together, it is difficult to revise, the shortcoming of portable difference, and reduced cost of development, update system interface and systemic-function dynamically, deployment makes things convenient for function to be easy to expansion, is well positioned to meet the demand of operator.

The present invention is achieved in that a kind of implementation method based on flash technology set-top box System Framework, it is characterized in that: may further comprise the steps:

Step 10, in set-top box the design a kind of can be to the parsing of file label in the flash file; Playing up and filling picture, literal and various vector graphics; Parsing and execution to the actionscript script; Execution to flash broadcast, time-out, forwarding operation; Decoding and broadcast to PCM, MP3, the embedded voice data of MP4; Receive process user message and comprise remote controller key message and timer message; Decoding work to jpg, png, bmp, zlib and character library; Flash player to the encapsulation function of operating system, timer, system function in the set-top box platform.

Step 20, design one set of modules comprise that program module, program searching module, system are provided with module and safety management module, and these modules are become corresponding module interface by the actionscript formal definition in the set-top box application programs;

Step 30, the module interface in the set-top box application program is registered association accordingly in set-top box;

Step 40, when the user by telepilot during to the set-top-box system interface operation, set-top box is defined as virtual key assignments with the code value of telepilot, and in set-top box, key assignments is converted into one to one the discernible operation of flash file, this moment, the flash player was resolved the flash file, and in set-top box, search module interface in the corresponding application program, finish required operation by the corresponding function that module interface calls in the described set of modules.

The advantage that the present invention has is: when the user by telepilot during to the set-top-box system interface operation, set-top box is defined as virtual key assignments with the code value of telepilot, and in set-top box, key assignments is converted into one to one the discernible operation of flash file, this moment, the flash player was resolved the flash file, and in set-top box, search module interface in the corresponding application program, finish required operation by the corresponding function in the module interface calling module, the present invention is update system interface and systemic-function dynamically, it is convenient to dispose, mutual effect is abundant, function is easy to expansion, is well positioned to meet the demand of operator.

[embodiment]

The present invention is further illustrated in conjunction with the embodiments below with reference to Fig. 1:

A kind of implementation method based on flash technology set-top box System Framework is characterized in that: may further comprise the steps:

Step 10, the flash player that a kind of parsing module by the swf file of design, render engine module, AS script parser modules, playback engine module, audio-frequency module, event processing module, Component Gallery module and platform interface module are formed in set-top box.
