Concept for picture/video data streams allowing efficient reducibility or efficient random access
A video data stream is rendered reducible in a manner so that the reduction leads to a restriction of pictures of the reduced video data stream to merely a predetermined sub-area of the pictures of the original video data stream and in a manner so that transcoding, such as re-quantization, may be avoided and a conformance of the reduced video data stream relative to the codec underlying the original video data stream be maintained.

Techniques are disclosed for dynamically generating a digital certificate for a customer server. A customer server creates a certificate profile and receives an associated profile identifier from a certificate authority (CA).
