The present invention is further defined to the 3rd processing unit, and detailed process is：Receive what display terminal was sent first
First request, and the first request type is judged, when the first request is watches online, directly by the chain of the video of request
Ground connection location is sent to display terminal and watched, and when the type of request is downloads, judges that the display of same video is downloaded in request
The number of terminal, if the number of display terminal is more, then while ask download to bring very big pressure to server, it is
Alleviate the pressure release bandwidth of server, peer network P2P association will be established between the display terminal that the present invention will ask to download
View, and a display terminal sends the video file downloaded thereto, then remaining display terminal can be according to pair of execution
Deng volume grid P2P agreements, the content with the display terminal sharing download, and then the pressure of server is alleviated, release bandwidth；
When the number for the display terminal that request is downloaded is few, the content of request is directly sent into each display terminal, when display terminal is watched
During video, timeline interface corresponding with the sequence of frames of video of each main view frequency or teaching courseware video is shown on its interface, can
With by the period on the control device selection time line such as remote control interface, and different requests is sent for the period,
When the surgical operation video in the period is watched in request again, corresponding video can be sent to display terminal by server
Watched, when to receive audio corresponding to teaching courseware in the period, audio piece corresponding to the period can be transferred
Section, and to the common factor situation between audio fragment and period come judge send audio fragment；When the second request is outer for viewing
During the operation details of section's operation, auxiliary video segment corresponding with the period can be transferred, and when asking to watch, user's tool
Body describes the detail of request viewing, after auxiliary video segment is picked out, adds label first for each auxiliary video segment,
Label can be conventionally added, the present invention is not specifically limited, and after having added label, is chosen in judging from each auxiliary video
The auxiliary video segment close with surgical operation detailed information is selected, then sends the auxiliary video segment by data transmission module
It to display terminal, when selecting immediate auxiliary video segment, can be selected according to existing method, such as can be, often
The label of one auxiliary video segment assigns a weights, then calculates weights corresponding to surgical operation details, selection and surgical operation again
The nearest weights of details, the imparting of weights can determine that the present invention does not do further restriction by convolutional neural networks model, lead to
Cross and the 3rd processing unit is specifically limited, can be according to different the first request and the second request respectively to request content
While doing different processing, and then meet user and need, bandwidth is saved, improves whole teaching efficiency.
The present invention is not limited to above-mentioned preferred forms, and anyone can show that other are various under the enlightenment of the present invention
The product of form, however, make any change in its shape or structure, it is every that there is skill identical or similar to the present application
Art scheme, is within the scope of the present invention.
