A transcoding technique for secure scalable stream

الملخص EN

Transmission of secured video stream from a centralized server to different clients is performed via a middle-ware transcoder server.

The role of this transcoder is to adapt the contents of a video stream.

Transcoding is performed to fit each client capability according to the change in network conditions.

This process should be performed while preserving the security of stream contents.

In this paper, we present a new model for the three tier transcoding architecture.

The objective of that model is to minimize the transcoding process while upholding the security aspect of the stream.
