It should be noted that left traffic track is receiving the corresponding with the first streaming media data stream ID of right traffic track return
, during streaming content data piece with fragment number sequence identification, occur what display was interrupted between right traffic track
Situation specifically includes two kinds of application scenarios, passively interrupts scene specifically: when right traffic track is driven out between left traffic track
Communication range, for example, if right traffic track be driven out to the communication protocol between left traffic track be RDP agreement, when right traffic
The left traffic track of orbital distance is more than 500 meters, then communication interaction cannot be carried out with left traffic track, so that left traffic track occurs
Display is interrupted, and is redefined intermediate traffic track and is continued the unfinished part of display, the left traffic track of such case is passively known
Occur interrupting and have certain delay, efficiency is lower, and in order to improve display efficiency, left traffic track can use active break side
Formula, i.e. active break scene specifically: in the case where GPS navigation device is installed on track vehicle, each rail traffic
Tool can obtain the current longitude and latitude data, that is, location information of track vehicle by GPS, so that each traffic track exists
It further include the location information of traffic track in the streaming media signal message of transmission, in such cases, left traffic track can basis
The location information that itself is reported with each traffic track, judges whether right traffic track reaches the critical of preset communication range
Area, if so, traffic track sends display interrupt instruction to the right, for example, if between right traffic track and left traffic track
Communication protocol be RDP agreement, the critical zone of preset communication range is right traffic track and when left traffic track moves toward one another,
It is critical zone with the range at a distance from left traffic track more than or equal to 400 meters, therefore, when left traffic track monitors right traffic rail
Road and left traffic track move toward one another and between left traffic track more than 400 meters when, to the right traffic track send display interrupt
Instruction, and the intermediate traffic track for continuing display is determined in time, improve display efficiency.
Step 204, it includes first streaming media data stream that the left traffic track is sent to the intermediate traffic track
ID and the display request message for interrupting fragment number, and receive the intermediate traffic track the returns and first-class matchmaker
Volume data stream ID is corresponding, since the interruption fragment number sequence identification streaming content data piece.

Table judges whether the Streaming Media list includes the first streaming media data stream ID, if so, returning to the left traffic track
Streaming content data piece corresponding with the first streaming media data stream ID, with fragment number sequence identification is returned, otherwise, inwardly
Content distributing network sends the display request message including the first streaming media data stream ID, and receives the content distributing network
Return it is corresponding with the first streaming media data stream ID, with the streaming content data piece of fragment number sequence identification and send
To the left traffic track.
Left traffic track inquires current all received streaming media signal message, if judgement knows that existing includes the
The streaming media signal message of one streaming media data stream ID, then explanation can not be utilized by the communication protocol between traffic track
Bandwidth resources between traffic track carry out Streaming Media from remaining traffic track and show, and need to be led to roadside dispatching desk
Letter obtains streaming medium content to be shown, wherein the communication protocol of traffic track and roadside dispatching desk includes 3G agreement, 3G long-term
Evolution (Long Term Evolution, LTE) agreement etc..Specifically: left traffic track sends to the roadside dispatching desk of ownership and wraps
The display request message of the first streaming media data stream ID is included, roadside dispatching desk carries out parsing acquisition to received display request message
Then first streaming media data stream ID inquires the Streaming Media list being locally stored according to the first streaming media data stream ID, judges to flow
Whether media list includes the first streaming media data stream ID, if it includes the first Streaming Media in local Streaming Media list that judgement, which is known,
Data flow ID, then traffic track returns to stream matchmaker corresponding with the first streaming media data stream ID, with fragment number sequence identification to the left
Hold data slice in vivo, if judgement knows do not include the first streaming media data stream ID in local Streaming Media list, to content point
Hairnet network send include the first streaming media data stream ID display request message, and reception content distribution network return with first
Stream medium data stream ID is corresponding, streaming content data piece with fragment number sequence identification, and is sent to left traffic track.It can
With understanding, whole streaming media data stream channel contents is stored in the content got up by several servers by network connection
