This project involved developing cloud DVR system that executed on IP Set Top Box. Client wants to add one more service known as DVR to the end user existing IP STB. This solution includes user interaction, so that user can select programs from EPG to be recorded in his account. Once user’s content recorded
Over the cloud, then user can view those contents by using set top box device, on laptop or PC by using web browser or mobile devices.
My responsibilities: - Design and development of complete record pipeline which includes below modules.
1) Record session manager
2) Transport stream chunker
3) Storage purge manager
4) Upload session manager.
Record session manager is responsible for creating record sessions and taking input feed from socket and provides this data to transport stream chunker module. TS chunker is responsible to break these continuous AV data stream to various chunks on flash storage memory and upload session manager is responsible to upload these chunks to cloud simultaneously.
Once chunks has been uploaded to cloud, in parallel Storage purge manager is responsible to purge these chunks from the storage. So that adequate memory always be available for new contents.
