METHOD AND DATA TRANSFER SYSTEM FOR SECURE TRANSMISSION OF VIDEO AND/OR AUDIO DATA VIA A NON-SECURE PUBLIC IP-BASED NETWORK

摘要

The invention relates to a method and data transfer system (10) allowing the transmission of video and/or audio data in a secure form and efficiently in terms of time via a public non-secure IP-based network, particularly the Internet. A secured VPN tunnel (5) is established from a transmitting device (40) to a receiving device (90) via the non-secure IP-based network (60). The video data to be transmitted are then encoded in a compressed video data stream and transmitted to the receiving device (90) via the VPN tunnel (50). The received video data stream is decoded there and provided to a first playback device (70).
