Encoding and encrypting devices for secure scalable data streaming
First Claim
1. A device for encoding and encrypting data, said device comprising:
- a segmenter adapted to receive said data and segment at least a portion of said data into regions;
a scalable encoder coupled to said segmenter, said scalable encoder adapted to scalably encode at least one of said regions into scalably encoded data; and
a progressive encrypter coupled to said scalable encoder, said progressive encrypter adapted to progressively encrypt at least a portion of said scalably encoded data into progressively encrypted scalably encoded data.

Abstract
A device and method thereof for encoding and encrypting data. The device includes a segmenter adapted to receive the data and segment at least a portion of the data into regions, a scalable encoder adapted to scalably encode at least one of the regions into scalably encoded data, and a progressive encrypter adapted to progressively encrypt at least a portion of the scalably encoded data into progressively encrypted scalably encoded data. In one embodiment, progressively encrypted scalably encoded data are provided to a packetizer in real time. In another embodiment, the device includes a storage unit adapted to store progressively encrypted scalably encoded data. In this latter embodiment, data can then be extracted from storage and provided to a packetizer.
