Patent abstract

The invention is an Internet access system that puts together interactivity of the Internet and congestion-free content delivery inherent in broadcast media in order to reduce delays in content presentation. The system delivers any web object (web page, music file, video etc.) in two steps. First, a single copy of object is downloaded according to a standard Internet protocol into a server provided at a broadcast center no matter how many client computers have requested the object; then the copy is transmitted over a broadcast channel according to a data broadcast protocol so that all clients could download it simultaneously. A web object is transmitted as a flow of packets and the transmission is preceded with an announcement specifying a broadcast channel and a flow number. The packet header contains a flow number and a destination address that could be a client address or a broadcast address, thereby enabling an efficient handling of both one-to-one and one-to-many transmissions. The system provides, when necessary, a protection of transmitted content against unauthorized reception by biding packets identity and transmitting packets of the same content over different, pseudorandomly changing channels.
