Class Relevant Data Sent after Class

Class relevant data are sent after class, including class total data,and some other important types of msg such as Appraise Message, Class Recording File Generated Message, Class Recording File Uploaded Message, EDU Answering msg, Watching Aata of Replay Page, App Replay Viewing Data and Chat in IM Classroom.

Since the system sets a 20 mins delay period for lessons, the above data will be pushed 20 mins after the end of the lesson at the latest.

Note: the unit of statistical duration is seconds

1.Class Summary Data

Class(lesson) summary data will be generated after the lesson is finished and pushed 20 minutes after the lesson end time in json format. The UID can be obtained in the registered user interface.

Added the new function of End Lesson for All in the ClassIn client and management console, and thus added RealCloseTime to judge the actual lesson end time. The judgment logic is as follows.

Judge whether the RealCloseTime field exists(Dropping the line or abnormal exit may result in no RealCloseTime field).

  • The RealCloseTime field does not exist: The CloseTime shall prevail.
  • The RealCloseTime field exists: When RealCloseTime = 0, the time of CloseTime shall prevail; when RealCloseTime != 0, please compare the values of RealCloseTime and CloseTime, whichever is smaller shall prevail.

This will be replaced by a new data structure on August 20. For details, see ## 7. Details of Viewing Playback in the ClassIn Client！！NEW！！

Data of the user watching lesson replay in ClassIn client. Data is pushed in real time after the user turns off replay.

User's Effective Replay Time(TotalLookVaildTime): The effective time of a user watching a playback on the ClassIn client is calculated as follows:

  1. The time spent on repeated viewing and on dragging the progress bar manually is not counted. Only the actual playback time of the progress bar is considered as the viewing duration.
  2. When the user exits the playback and watches it again, the duration of the previously watched parts will not be included in the calculation. Only the duration of the unplayed parts will be considered.
  3. If there are multiple replays of a classroom, the total effective duration of all the videos will be calculated.
Key Type Instruction
Cmd String 'ClientPlaybackDataDetail'
ClassID int lesson ID
Data object Content
└ UID int user UID
└ TotalLookCount int The total number of times the classroom playback was viewed on the client side.
└ TotalLookTime int Cumulative viewing duration of a user, in seconds.
└ TotalLookVaildTime int User's effective replay Time. Unit in seconds.
