Embodiment
The present invention provides the port based on interchanger and the mapping method and system of Network Personal Video Recorder passage, to make the present invention
Purpose, technical scheme and effect it is clearer, clear and definite, the present invention is described in more detail below.It should be appreciated that this place
The specific embodiment of description only to explain the present invention, is not intended to limit the present invention.
A kind of port based on interchanger provided by the present invention and the method for Network Personal Video Recorder passage automatic mapping, it is wrapped
Include step：
S1, Network Personal Video Recorder obtain the address information of web camera by interchanger, are inquired about according to the address information
The port numbers of web camera；
S2, the logical channel number (LCN) of the port numbers of the web camera and Network Personal Video Recorder mapped, according to described
Display location corresponding to logical channel number (LCN) determination；
S3, to web camera application code stream, and it is aobvious that the code stream applied is carried out on corresponding display location to decoding
Show.
In the present invention, the port numbers of web camera are first obtained, then by a pair of port numbers and logical channel number (LCN) progress 1
Should, that is, mapped, so that it is determined that the display location of map network video camera, then the code stream of web camera is obtained, and right
Answer and decoding is carried out on display location show.Due to making port numbers and logical channel number (LCN) realize mapping in the present invention, so adding
After adding web camera, can also ensure to be not in out of order situation.
The typical case scene of the present invention is as shown in figure 1, left side is connection interchanger 200 (LAN SWITCH) in figure
Network Personal Video Recorder 100 (NVR), Network Personal Video Recorder 100 even connected to the Net video camera 300 (IPC) by interchanger 200, each
Web camera 300 is ordered as 1~8 successively according to the port numbers (network port number) of insertion, and right side is display 400, specifically
It is to be output data to by Network Personal Video Recorder 100 on display 400, is needed to be generally divided into 8 logical channels according to display,
Sequence number is followed successively by 1~8, and LAN SWITCH are exactly that the port of interchanger 200 and the logic of Network Personal Video Recorder 100 are led to by the present invention
Road corresponds to automatically one by one.That is, the port numbers have 8, corresponding logical channel number (LCN) has 8.
