A METHOD FOR CREATING AN ENHANCED DATA STREAM |
摘要 |
The present invention provides a method for secure communication of digital information between a transmission entity and at least one reception entity. The method may be applied in the domain of audio/video data transmission, where stuffing data packets comprising random payloads are inserted into a transport stream along with true data packets comprising the audio/video data. The dummy data packets are detectable by an authorised reception entity but not detectable by unauthorised reception entities. A large number of stuffing data packets are included in the transmission to occupy bandwidth and to further render the job difficult for an unauthorised reception entity which tries to intercept the transmission. |
