Further, described frequency spectrum purpose monitoring device is a spectrum analyzer.
Further, described terminal monitoring monitoring subsystem is used for carrying out purpose monitoring to the file that sub-headend and chained service site receive, thus obtains reception integrity degree and the packet loss of described file.
Further, also comprise:
Picture purpose monitoring subsystem, be connected with described code stream purpose monitoring subsystem, treat that the video file in the described file that satellite pushes carries out resolving and stores to what receive from described code stream purpose monitoring subsystem, and then shown in the mode of a speed or multiple velocity by the mode of many pictures, thus purpose monitoring is carried out to described video file.
Further, terminal monitoring monitoring subsystem also comprises:
Passback device, is connected with described picture purpose monitoring subsystem, and reception integrity degree and the packet loss of the described file obtained by described terminal monitoring monitoring subsystem return to described picture purpose monitoring subsystem.
The file that purpose monitoring system of the present invention is received by signal and the terminal of the data transmitted up link Satellite, the transmission of down link Satellite carries out purpose monitoring.Thus when the quality of the file that user receives is lower, operation maintenance personnel quick and precisely can analyze the lower reason of document quality and come across up link, down link or terminal, to remove the fault causing document quality lower fast and accurately, thus ensure that the file that user receives has higher quality.
The monitoring and surveying result of frequency spectrum purpose monitoring device of the present invention directly can reflect the spectrogram of the signal that down link Satellite transmits, and around purpose monitoring signal, whether have the type of interference signal existence and interference signal, according to the type of the interference signal analyzed, can the source of locating interferers fast, thus in time interference signal is removed.
Before satellite pushes, the mode that the video and audio index that picture purpose monitoring subsystem of the present invention can treat the video file in the described file of propelling movement is shown with a speed or multiple velocity by many pictures carries out purpose monitoring, thus in source to the quality of video file in addition control.
According to hereafter by reference to the accompanying drawings to the detailed description of the specific embodiment of the invention, those skilled in the art will understand above-mentioned and other objects, advantage and feature of the present invention more.
Accompanying drawing explanation
Hereinafter describe specific embodiments more of the present invention with reference to the accompanying drawings by way of example, and not by way of limitation in detail.Reference numeral identical in accompanying drawing denotes same or similar parts or part.It should be appreciated by those skilled in the art that these accompanying drawings may not be drawn in proportion.In accompanying drawing:
Fig. 1 is the indicative flowchart of satellite transmission purpose monitoring system according to an embodiment of the invention;
Fig. 2 is the indicative flowchart of satellite transmission purpose monitoring system in accordance with another embodiment of the present invention.
Embodiment
In the embodiment shown in fig. 1, satellite transmission purpose monitoring system provided by the invention, comprising:
Code stream purpose monitoring subsystem 10, is connected with up link, and carries out purpose monitoring to the data flow of satellite transmission in the uplink;
Signal monitoring monitoring subsystem 20, is connected with down link, and carries out purpose monitoring to the signal of down link Satellite transmission;
Terminal monitoring monitoring subsystem 30, is connected with terminal, and carries out purpose monitoring to the file that terminal receives, thus obtains reception integrity degree and the packet loss of described file.When the quality of the file that user receives is lower, operation maintenance personnel quick and precisely can analyze the lower reason of document quality and come across up link, down link or terminal, to remove the fault causing document quality lower fast and accurately, thus ensure that the file that user receives has higher quality.
In one embodiment of the invention, described signal monitoring monitoring subsystem comprises:
Whether frequency spectrum purpose monitoring device, for having interference signal to exist around the spectrogram of signal described in purpose monitoring and described signal.Dissimilar interference signal, spectrogram has the different forms of expression, is changed come Analysis interference type and intensity by spectrogram, can effectively carry out preventing and correcting.
In one embodiment of the invention, described frequency spectrum purpose monitoring device is a spectrum analyzer.
Consider that user may worry the problem of personal secrets, described terminal monitoring monitoring subsystem of the present invention is selected to carry out purpose monitoring to obtain reception integrity degree and the packet loss of described file to the file that sub-headend and chained service site receive, but not carries out purpose monitoring to the file that user receives.When actual monitored is monitored, can select several more typical sub-headend and chained service site, set up control point, statistics file receives integrated degree, packet loss voluntarily, and each file terminal after a few carousel receives the indexs such as integrity degree.
