In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The embodiment of the present invention provides a kind of method for receiving and processing data based on Set Top Box, after receiving PSI/SI segment data, only needs copy PSI/SI segment data just to resolve it, substantially increases the receiving efficiency of PSI/SI segment data.
The invention provides a kind of method for receiving and processing data based on Set Top Box and device:
Described method comprises:
The some PSI/SI segment datas received are stored to hardware multiplexing buffering area;
One by one described PSI/SI segment data is copied in the demultiplexing task buffering area of some dynamic assignment;
Resolve the PSI/SI segment data in described some demultiplexing task buffering areas.
Described device comprises:
Data receipt unit, for being stored to hardware multiplexing buffering area by the some PSI/SI segment datas received;
Data copy cell, for copying in the demultiplexing task buffering area of some dynamic assignment by described PSI/SI segment data one by one;
Data Analysis unit, for resolving the PSI/SI segment data in described some demultiplexing task buffering areas.
In order to technical solutions according to the invention are described, be described below by specific embodiment.
Embodiment one:
Be illustrated in figure 1 the method flow diagram of the preferred embodiment of a kind of method for receiving and processing data based on Set Top Box provided by the invention, for convenience of explanation, illustrate only the part relevant to the embodiment of the present invention.
In step S101, the some PSI/SI segment datas received are stored to hardware multiplexing buffering area.
In embodiments of the present invention, the some PSI/SI segment datas received, after receiving some PSI/SI segment datas, are directly stored to hardware multiplexing buffering area by Set Top Box.Wherein, hardware multiplexing buffering area is divided into polylith, and each block is for storing a PSI/SI segment data, and the maximum length of PSI/SI segment data is 4KB, and therefore one piece of hardware multiplexing buffering area is 4KB to the maximum.Generally speaking, the size of hardware multiplexing buffering area to be 4nKB, n be greater than 1 integer.
In step s 102, respectively PSI/SI segment data is copied to one by one in the demultiplexing task buffering area of some dynamic assignment.
In embodiments of the present invention, in Set Top Box, preset understanding demultiplexing tasks to be used for copying PSI/SI segment data.Whenever receiving a PSI/SI segment data, and after being stored to hardware multiplexing buffering area, just will there is the message informing demultiplexing task of PSI/SI segment data in demultiplexing task buffering area in Set Top Box.Demultiplexing task is dynamic assignment demultiplexing task buffering area then, then PSI/SI segment data is copied in the demultiplexing task buffering area of this dynamic assignment.By that analogy, one by one PSI/SI segment data is copied in the demultiplexing task buffering area of some dynamic assignment.Maximum length due to PSI/SI segment data is 4KB, and thus the size of demultiplexing task buffering area is also 4KB.
In step s 103, the PSI/SI segment data in some demultiplexing task buffering areas is resolved.
In embodiments of the present invention, demultiplexing task, after PSI/SI segment data is copied to demultiplexing task buffering area, obtains the resolving information of PSI/SI segment data in demultiplexing task buffering area.The speed receiving PSI/SI segment data due to Set Top Box is higher than the speed of set-top box parses PSI/SI segment data, is added in a queue by the resolving information of PSI/SI segment data in the demultiplexing task buffering area of acquisition, one by one etc. to be resolved.Therefore, the resolving information of PSI/SI segment data in the some demultiplexing task buffering areas obtained is added in queue, resolves the PSI/SI segment data in homographic solution demultiplexing tasks buffering area one by one according to the resolving information in queue.Wherein, resolving information includes but not limited to: the information (because only having in demultiplexing task buffering area the resolving information that just can obtain PSI/SI segment data when there is PSI/SI segment data) that there is PSI/SI segment data in demultiplexing task buffer zone address information and demultiplexing task buffering area.Size for the queue of storing and resolving information is arranged according to the processing speed of resolving PSI/SI segment data.
In embodiments of the present invention, parsing task has been preset for resolving PSI/SI data in Set Top Box, a PSI/SI segment data often copies to after in the demultiplexing task buffering area of a dynamic assignment by demultiplexing task, just the message comprising this PSI/SI segment data resolving information is added into rear of queue, parsing task takes out resolving information one by one from queue stem, and resolves the PSI/SI segment data in homographic solution demultiplexing tasks buffering area one by one according to taken out resolving information.
In step S104, the demultiplexing task buffering area of PSI/SI segment data has been resolved in release.
In embodiments of the present invention, due to after receiving PSI/SI segment data, only need copy PSI/SI segment data just can resolve it, substantially increase the reception treatment effeciency of PSI/SI segment data, even if PSI/SI segment data is sent by higher data transfer rates, all segment datas that same PSI/SI shows also can be received within a short period of time.
Embodiment two:
Fig. 2 is the structural representation of the preferred embodiment of the data receiver processing unit that the present invention is based on Set Top Box, for convenience of explanation, illustrate only the part relevant to the embodiment of the present invention.The unit that this device can be the software unit be built in Set Top Box, hardware cell or software and hardware combine, or be integrated in the application system of Set Top Box or Set Top Box as independently suspension member.Wherein:
Data receipt unit 21, for being stored to hardware multiplexing buffering area by the some PSI/SI segment datas received.
Data copy cell 22, for copying in the demultiplexing task buffering area of some dynamic assignment respectively one by one by PSI/SI segment data.
Data Analysis unit 23, for resolving the PSI/SI segment data in some demultiplexing task buffering areas.
In embodiments of the present invention, Data Analysis unit 23 comprises two modules, is respectively:
Resolving information acquisition module 231, for being added into the resolving information of PSI/SI segment data in the some demultiplexing task buffering areas obtained in queue.
