AN EXPERIMENTAL APPROACH TO THE USE OF PROXY SERVERS IN TIME-SHIFTED TV

The Internet Protocol Television services (IPTV) highly popular nowadays are based on IP protocol which supports broadcast and unicast services such as the Broadcasting of TV channels, Video On Demand and Time-Shifted Television. Distribution of individual television streams to viewers imply demands of considerable bandwidth and this could be challenging for network operators and telecommunication companies. The use of caching proxy servers could be a solution to this. This paper illustrates an experimental approach which showed high efficiency in proxy servers providing Time-shifted television allowing customers to watch content regardless of the time of broadcast.
