An embedded system for video processing comprises hardware means for realizing the following functions: a) a server function, wherein for realizing the server function the following functions are realized: a1) receiving of at least one image-, at least one audio-data stream; a2) compression of at least one of the image- and audio-data streams yielding in each case a combined data stream respectively; a3) output of at least one of the combined data streams via a protocol based network; b) a client function, wherein for realizing the client function the following functions are realized: b1) receiving of at least one combined data stream from the protocol based network; b2) decompression of the at least one combined data stream; b3) output of the combined decompressed image- and audio-data stream; c) wherein the hardware means are designed in such a way that they c1) compress and decompress a continuous combined data stream and c2) conduct an individual security measure by means of a hardware serial number saved in the system and/or an individual activation code and c3) comprise activation code monitoring means, which conduct a monitoring and comparison of activation codes.
