A computer program product containing executable instructions for performing a method. as stated in Claims 1 to 35 when performed on a computer. 4 2. Set-top box for decoding the received stream containing audio signals. The set-top box contains a claim 38 decoder for current monitoring. Information received 4 3. A portable electronic device for decoding a received stream consisting of an audio signal, whereas a portable electronic device contains a claim decoder 38 for verifying the received stream 4 4. A computer for decoding a received stream consisting of an audio signal, wherein the computer is equipped with a claim decoder 38 for checking the received stream 4 5. Broadcasting system for transmitting a data stream consisting of an audio signal, whereby the system broadcasts a signal and consists of a claim encoder 37 4 6. Method for connecting the first and second bit currents together. where each stream will It consists of multiple data frames and cryptographic values coupled with a given number of data frames, wherein the method consists of - generating bit streams concatenated from the first and second bit streams. where the bit current to weld Together they consist of at least part of the multiple data frames from the first and second bit streams. and contains cryptographic values that are generated and inserted according to any of the methods specified in Claims 1 to 35. 4. 7. Attachments are available to concatenate the first and second bit streams, where each stream consists of multiple data frames and cryptographic values coupled with a given number of data frames, where The encoder consists of - Claims encoder 37 for encoding the last frame of the first bit stream and the frame. First of the second bit stream 4 8. Attachment as specified in claim 47, which also contains - forwarding unit for forwarding the frame and the coupling cryptographic value of the first bit stream and the second which is not decrypted and encrypted 4 9. Attachments as specified in Claim 47 or 48, which also consist of Claim 38 decoder for decoding the last frame of the first bit stream, the first frame of the second bit stream and the accompanying cipher to determine the reliable condition. of the first and second bit streams and a control unit which allows the encoder to insert the cryptographic value into part of The bit stream is only when the corresponding first and second bit streams are proven to be real.
