Embodiment
The present invention uses the hierarchical coding technology on the control point terminal, according to the upstream bandwidth situation video data is transmitted at the network higher slice, and receiving terminal selects part or total data layer to receive according to bandwidth situation, to reach the purpose of network bandwidth adaptive.
The hierarchical coding technology be meant with a frame video image be divided into several independently the layer encode, wherein comprise a basic layer and some enhancement layers, basic layer expression passed through the additional image detail of Network Transmission by the minimum image of network with acceptable mass transport when enhancement layer is represented to have enough remaining bandwidths available.By an every layer data size and an original frame data sizableness after the network hierarchy coding.Basic layer can be by independent decoding, also can be simultaneously decoded with enhancement layer.Enhancement layer can not be decoded separately, and the picture quality that the many more decodings of enhancement layer obtain is good more.
2 pairs of video data pass-through modes of the present invention embodiment is elaborated with reference to the accompanying drawings:
(1) the control point endpoint registration is to signal server;
(2) address of signal server notice control point terminal forwarding server;
(3) the control point terminal is selected forwarding server according to oneself network bandwidth ability and video encoding capability;
(4) receiving terminal initiates a session request to signal server (not shown), requires to watch the video of specifying the control point terminal;
(5) signal server notice control point terminal is initiated video session;
(6) the control point terminal sends to the video data layering in the corresponding forwarding server, simultaneously video transmission information is sent to signal server;
(7) signal server circulates a notice of the video information of this control point terminal and the address of forwarding server to receiving terminal;
(8) receiving terminal receives video data and the demonstration that is fit to according to the bandwidth ability of oneself.
In another embodiment, video data repeating process of the present invention is described as follows:
(1) the control point endpoint registration is to signal server;
(2) network bandwidth ability and the video encoding capability of control point terminal announcement signal server control point terminal;
(3) signal server is assigned forwarding server according to the network bandwidth ability and the video encoding capability of control point terminal to the control point terminal;
(4) receiving terminal initiates a session request to signal server, requires to watch the video of specifying the control point terminal;
(5) signal server notice control point terminal is initiated video session;
(6) the control point terminal sends to the video data layering in the corresponding forwarding server, simultaneously video transmission information is sent to signal server;
(7) signal server circulates a notice of the video information of this control point terminal and the address of forwarding server to receiving terminal;
(8) receiving terminal receives video data and the demonstration that is fit to according to the bandwidth ability of oneself.
In above two embodiment, the control point terminal sends to some or all of data Layer in the forwarding server by different connections according to the upstream bandwidth situation, must comprise basic layer in the data Layer of transmission.As shown in Figure 2, control point 1 is because upstream bandwidth is limited, only sent three figure layer data to forwarding server, wherein sent a base layer data of necessary transmission, sent an enhancement data respectively to forwarding server 2 and forwarding server 3 to forwarding server 1.Control point 2 is owing to have higher bandwidth, the data of five figure layers have been sent to forwarding server, wherein sent a base layer data of necessary transmission, sent an enhancement data respectively to forwarding server 2, forwarding server 3, forwarding server 4 and forwarding server 5 to forwarding server 1.
The some or all of data Layer that receiving terminal selects needs to receive according to the network bandwidth situation of oneself.Similarly, basic layer also must be received.As shown in Figure 2, receiving terminal 1 is because downlink bandwidth is higher, receive the data of five figure layers, comprising a base layer data from forwarding server 1 that must receive, receive a enhancement data simultaneously from forwarding server 2, from an enhancement data of forwarding server 3, from enhancement data of forwarding server 4 with from an enhancement data of forwarding server 5.Receiving terminal 2 is because downlink bandwidth is limited, can only receive the data of three figure layers, comprising a base layer data from forwarding server 1 that must receive, receive simultaneously from enhancement data of forwarding server 2 with from an enhancement data of forwarding server 3.The enhancement layer that receives is many more, and the image quality that obtains after decoded is good more.For the user of limited bandwidth, can select to receive only basic layer and part enhancement layer, in the sacrificial section definition, guaranteed the smoothness of its video like this, the user of bandwidth abundance can selective reception more data layer to obtain better video effect.
Preamble has schematically been described a plurality of different forwarding servers receptions and has been sent data, need to prove that these a plurality of different forwarding servers can be integrated on the hardware device.
By video data pass-through mode and control point terminal hierarchical coding technology as can be known, the control point terminal can send the video data of respective numbers according to the bandwidth situation of oneself, receiving terminal also can be according to the some or all of video data of bandwidth situation selective reception of oneself, thereby reaches the purpose of network bandwidth self adaptive.
The real-time video monitoring system of adaptive bandwidth of the present invention can be applied to convenience store, bank etc. needs real-time video monitoring and band-limited place.
Specific embodiments of the invention at be real-time video monitoring system, for the real-time audio supervisory control system, the bright adaptive bandwidth method of we is suitable for too.
Obviously, under the prerequisite that does not depart from true spirit of the present invention and scope, the present invention described here can have many variations.Therefore, the change that all it will be apparent to those skilled in the art that all should be included within the scope that these claims contain.The present invention's scope required for protection is only limited by described claims.
