DLL) interface, this socket meets JSON RPC 2.0 specification, uses http protocol transmission；
3. the functional interface API of client call service end realizes function.
Based on this api interface, client and service end have the feature that alternately
1) client can be other networked devices such as mobile phone or PC, it is also possible to and service end is at an equipment.Client kimonos
The API interaction data of business end transmits on the http protocol.The meaning using http protocol transmission is conveniently to enter in a browser
Row accesses, and is also convenient for relevant function application section to be deployed on front-end WEB server.
2) described http protocol is specially and uses HTTP POST method or HTML5WEB SOCKET both modes to transmit.
Use HTTP POST method can bring load, the parameter of transfer complex, AJAX can be used again easily on browser page
(Asynchronous JavaScript and XML) calls；Use WEB SOCKET mode can keep alternately client and
The connection of service end, reduces expense.
3) load data transmitted meets JSON RPC 2.0 specification；This specification is mainly characterized by being sent a JSON by client
Data, service end returns JSON data and carrys out complete call, and the JSON data sent and return are specified by specification；With
JSON form is as mutual data form, and it is advantageous that in browser that Javascript can directly process JSON data is
The object of Javascript, Javascript object can also be converted directly into JSON data, uses very convenient.
As it is shown in figure 1, from HTTP client, it is common that run in the Javascript script of the html page on browser, send out
HTTP POST request, request is sent to be sent to service end http server, JSON RPC 2.0 specification in http server
Load data is delivered to JSON RPC 2.0 processing module, and processing module is called bottom layer driving interface and OS etc. and completed funcall,
Return value returns to http server, and http server returns to client return value.
4) transmission can select to support HTTPS agreement；The effect of this agreement is can be with the data of encrypted transmission, to transmission data
Safety can be adopted in this way when requiring.
5) for the call address of audio, video data, the URL address meeting http protocol or RTSP agreement is used.Player
Certain digital television program can be play, the parameter such as frequency specifying TV programme in address parameter by this address.There is provided
Such URL interface is convenient to be played out in player.In this manner, client player sends HTTP or RTSP
Request, service end receives request, obtains the parameter that program is relevant, carry out descrambling and from biography by these parameters from request address
Defeated stream filters the audio, video data of appointed program, and returns to client by agreement and play out.
6) transmission of HTTP POST method can support that XML HttpRequest Level 2, the i.e. AJAX of the second layer call,
Namely support cross-domain transmission.This needs service end support to use.Here XMLHttpRequest is for HTML
In the page, Javascript calls the Javascript object of POST method.Use this object reference method to complete POST
Method call.The XMLHttpRequest of the second layer supports cross-domain transmission.Thus the function of DTV can be passed through HTML
The page is deployed in front end, and terminal uses the general browser in Set Top Box.During browser performs, from the HTML of front end website
Just can be called the function on set-top box device by XMLHttpRequest in Javascript code in the page, address can
Directly to use http: // 127.0.0.1.Cross-domain transmission is the New function of HTML5, if not supporting, it is impossible at a website
The page on by XMLHttpRequest to another one site requests data.
Being presented herein below one to call, transmit data instance, client sends request, allows the method calculating of service end summation (sum)
1+2, (wherein italics is the load data of HTTP transmission):
POST/dvb/rpc HTTP/1.1
Host:192.168.60.10:18080
Content-Length:38
Content-Type:text/plain；Charset=UTF-8
{"id":1,"method":"sum","params":[1,2]}
Service end return data:
HTTP/1.1 200OK
Content-Type:application/jsons
Content-Length:45
{"jsonrpc":"2.0","result":3,"id":1}
Above-mentioned transmission example call data encapsulation process as in figure 2 it is shown, when calling service end and carrying out 1+2, be first
Definition method name is sum, and parameter is the array of JSON form, and array element is numeric type, is then packaged as JSON RPC
The data of 2.0 specifications, are sent to service end by POST, can be plus the transmission head of HTTP when POST sends.Service end HTTP
Server receives transmission data, obtains the load data for JSON RPC2.0 cannonical format, parses method name and parameter,
Calculating result by local function module, result is returned to client by http server, client parses JSON
Data, parse end value 3 further.
