  1. Run the 4DPD program on the DM/PD PC, proceed with “Connect”, and run Interactive Vod after completing the Group and Interactive Vod Title settings on the Record Tab.

  2. Through load balancing, interactive VOD data is delivered to the IMS server.

  3. The interactive VOD data received from the IMS server is sent to 4DMC to create transcoding and video segments and manifest files.

  4. The created files are stored in the AWS S3 in the form of Master Playlist and Media Playlist for use as I.VOD.

  5. Convert the video sources of each camera channel to 4DHLS format and register the converted URL information.

  6. Playlist (m3u8) & segment information in AWS Media Store is forwarded to the Cloud Front.

  7. Transfer the contents list (Master/Media Playlist) of the CMS to the Mobile APP or Web Player. When the client clicks the CMS's Content List, the CMS forwards the video clips and video URLs from AWS S3 to AWS Cloud Front.

  8. AWS Cloud Front uses the HTTP protocol to deliver to the Mobile 4DHLS SDK or the Web Player.

  9. Users can watch 4DInteractive VOD videos through mobile or web players.
