Abstract

ID696687

This text was extracted from a Microsoft Word document.
This is the abbreviated version, containing approximately 100% of the total text.

Proposed is to combine trick mode and stream security, in particular for system with partially accessible connections, such as PCs.

In an inaccessible part of the system, a parser (I-frame detector) behind the decryptor passes I frames to the decompressor.

The parser may interact with a control processor (e.g. for user interface) in the accessible part.
