At present, the TR-069 agreement is often adopted in the communication between STB and the STB management system.TR-069 is one of technical specification of being developed by DSL forum, and its full name is " a CPE wide area network management agreement ".It provides the general framework and the agreement of home network device in the next generation network being carried out administration configuration, is used for from network side equipment such as the gateway of home network, router, STB being carried out the remote centralized management.With the alarm is example, and the reciprocal process of TR-069 agreement is as shown in Figure 1.In the whole reciprocal process, need to accomplish two complete transmitting-receiving processes between STB and the STB management system.
Under the interactive mode of TR-069, all data all adopt the SOAP mode to encode, and therefore all data of transmission all are the XML forms, and the mode of typical SOAP coding is following:
Through the interactive mode of TR-069, STB and box end management system can well be carried out communication, but the efficient of this interactive mode is also low relatively.At first, a simple data interaction needs two complete HTTP interaction flows, because the set-top box CPU data-handling capacity is lower, response speed is slow, causes whole reciprocal process long, has significantly reduced the quantity of separate unit management system supervisor top box; Secondly, the coded system of XML relatively expends cpu resource, and the data volume behind the coding is bigger.These all for all relatively limited STB of internal memory and cpu resource duty ratio bigger.
Simultaneously, JSON (Java Script Object Notation) is the simplification coding method of a kind of XML, is used for accomplishing at the network two ends serializing and the unserializing process of object.SOAP is a kind of data interchange format of lightweight, is easy to the people and reads and write, and also is easy to machine simultaneously and resolves and generate.SOAP is based on JavaScript Programming Language, the sub-set of Standard ECMA-262 3rd Edition-December 1999.JSON adopts the text formatting that is totally independent of language, but has also used the custom (comprising C, C++, C#, Java, JavaScript, Perl, Python etc.) that is similar to the C family of language.These characteristics make JSON become desirable exchanges data language.
JSON to as if unordered " ' name/value ' a to " set.An object finishes with " { " (left bracket) beginning, " } " (right parenthesis).": " (colon) of each " title " heel; Use ", " (comma) to separate between " ' name/value ' to ".
Above-mentioned typical SOAP code conversion becomes the JSON format content following:
{″category″：″classifieds″}。
Summary of the invention
The objective of the invention is to have overcome above-mentioned shortcoming of the prior art; A kind of internal memory and cpu load that can effectively reduce STB is provided; The efficient of data interaction is provided, and then increases the quantity of management system supervisor top box, and application mode is simple; With low cost, range of application is the means of communication between terminal set top box and central office terminal's top box management system in the digital TV network comparatively widely.
