Fig. 2 is the block diagram of the management system of multimedia stream protocol of the present invention.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in further detail.
Core concept of the present invention: because the operation of Media Stream has more general character, so can adopt the method for definition general character operational order, these general character operational orders are write on the general character operational order module, when newly adding media stream protocol, the operational order that newly adds media stream protocol is defined as a plug-in unit agreement adds on the general character operational order module, realize the same management of multimedia stream protocol.
As shown in Figure 1, the invention provides a kind of management method of multimedia stream protocol, it is realized flowing out and comprises the steps:
110, define the general character operational order of multimedia stream protocol, make the operation of simple, fast each agreement of compatibility of terminal equipment energy, such as the broadcast of media file, suspend, withdraw from, F.F. and rewind down etc., and these general character operational orders are write on the general character operational order module;
120, the sets definition that the more than one operational order of certain agreement is formed is an agreement plug-in unit, and the agreement plug-in unit is written on the described general character operational order module, for a kind of initiate media stream protocol, only need a newly-built agreement dongle configuration, and write and represent the member function of each basic operation to get final product; Such as, rtsp agreement for standard, according to the general character operational order that defines, can determine to play, suspend, withdraw from, several operational orders such as F.F. and rewind down form rtsp agreement plug-in units, the realization of operational order is finished by rtsp plug-in unit inside, and upper layer logic control need not be known the realization details;
Wherein, when definition agreement plug-in unit, the more than one operational order of certain media stream protocol can be encapsulated in the function pointer structure, and each function that defines in this structure is represented a kind of operation, the all operations instruction functions of certain media stream protocol is all as a member of function pointer structure, for example, play, suspend, withdraw from, operational order function such as F.F. and rewind down is as the member of rtsp agreement dongle configuration;
130, when media stream signal is imported, read the protocol header of media stream protocol, perhaps some flag bit points to the corresponding protocols plug-in unit with overall agreement plug-in pointer dynamically, calls this media stream protocol then and parses relevant information in the Streaming Media signal.Such as, the employed URL of rtsp agreement (Uniform Resoure Locator, uniform resource locator) is usually with rtsp: // beginning, can select rtsp agreement plug-in unit dynamically for use according to this feature, and the pairing time-out of rtsp agreement, broadcast etc.; Wherein upper layer logic is only called the pre-defined general character operational order that comes out, and promptly overall interface does not need to understand the realization details of concrete agreement for some operations;
The present invention also comprises a kind of management system of multimedia stream protocol, as shown in Figure 2, comprises general character operational order module and agreement card module; On described general character operational order module, defined the general character operation of multimedia stream protocol, one function pointer structure wherein is set on the agreement card module, be used to encapsulate the operational order of a plurality of separate single medium stream protocols, and each function in the described function pointer structure is represented an operational order.
