Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
In the present invention, caused new data in the conference process served as theme with PPT, such as：PPT page turnings, notes, circle
Picture, audio frequency and video etc., all it can be described as " knowledge point ".
Technical scheme provided by the invention is directed to the playback of automatic storage PPT data in meeting, for being remembered in a manner of imaging
The mode of the data storage of video is recorded, can only be played from the beginning in playback, and for conferencing data is carried out at fragmentation
Storage mode after reason, then it can select " knowledge point " to be watched in playback.
During data storage, first by image data (including photo current and the photo current in PPT data
Time of origin) it is stored in cloud server, then by the photo current received to the more matchmakers occurred between lower one page picture
Volume data carries out fragmentation and is processed and stored at cloud server.
The storage mode of different types of multi-medium data is illustrated individually below：
(1) for PPT data
When speaker is carrying out PPT page turnings during explanation, one page PPT currently shown is downloaded, by what is currently shown
One page PPT is converted to picture format, and records the time of origin of the PPT page-turning instructions.
(2) for note data
When speaker is in the notes write during explanation, the word of writing can be divided according to stroke, often
Data includes the data of stroke and the writing time of each stroke.Or can also to the word of writing with when
Between divided for unit, for example, in seconds, i.e., per data in comprising the stroke in 1 second, and in seconds, record is currently
Time.
(3) for audio, video data
For explanation audio or video of the speaker in conference process, divided in units of the time, for example, using the second to be single
, i.e., the audio or video data of 1 second are included in every data, and record current time in seconds.
For the storage mode of above-mentioned multi-medium data, the invention discloses a kind of data playing method, as shown in figure 1,
Comprise the following steps：
Step 101：Receive the playing request of an image data；One image data includes one in PPT data
The time of origin of page data and the page of data in the PPT data.
Step 102：Obtain an image data, and from the time of origin of an image data to next
The multi-medium data of fragmentation between the time of origin of image data；The multi-medium data of the fragmentation is included with default
