The general flow of system, as shown in figure 3, Streaming Media request initiated by player, carries stream media information, cookie, use
Family information, such as：Streaming Media ID itemID, ID userID.After adapter responsor Servlet receives request,
Pass to adapter transducer Parser.Adapter transducer Parser analysis request parameter, with all solicited message constructing variables
Processor RequestParams (store valuable information in the player requests such as Streaming Media ID, ID, and this parameter
The non-real physical device of processor RequestParams, this processor is an object in internal memory, and object has the data of oneself
Structure, has the attribute of oneself, and attribute number does not limit.Solicited message is stored in the attribute of RequestParams respectively.).Adapter
Transducer Parser takes parameter Processor RequestParams having constructed, and original system required parameter is such as：Streaming Media ID
Sid, ID uid, adapter Parser realizes the conversion of parameter, and itemID switchs to sid, and userID switchs to uid (conversion
It is to construct existing parameter Processor, so throw in engine and be not required to change interface, you can identification.), construct existing parameter
Processor, returns to adapter Servlet.
Adapter responsor Servlet obtains Streaming Media material to throwing in engine.After taking material, adapter responsor
Servlet will arrange material information.Because the agreement returning to player is different from existing agreement, adapter responsor
Servlet, according to agreement, player desired data is carried out assembly by character string, material information is assembled into the lattice of new agreement
Formula, returns to player.The assembly of one-to-one agreement simply realized by every kind of adapter.

Transducer Parser can obtain player requests information.
Perform () realizes solicited message translation function.Perform () takes from parameter Processor RequestParams
The data of storage, according to the implication of value, change data form, is stored in existing parameter Processor.If do not changed, throw in engine
Then None- identified, need to make the input engine of a differentiation again, and development cost is huge.
With reference to Fig. 3, different player requests, so-called difference is that agreement is different, specifically has two kinds of situations：One is parameter name
Difference, two is parameter list different (such as new parameter, or some parameters of disappearance), between adapter transducer Parser is according to parameter
Mapping relations, implication identical value is mapped, and the value of new parameter is passed through to change parameter Processor RequestParams, enters
Row storage.The informative differentiation that the different player requests of shielding are brought just is realized in.For example：Existing player parameter
ABC, new player parameter ABD, for new parameter D, parameter C can be mapped to, be stored in the space of C.If new player parameter is
ABCD, then need to change existing parameter Processor RequestParams, increases parameter D.
3) adapter responsor Servlet：
