Abstract EN
In recent years, many telecommunication companies have regarded IP network as a new delivery platform for providing TV services because IP network is equipped with two-way and high-speed communication abilities which are appropriate to provide on-demand services and linear TV programs.
However, in this IPTV system, the requests of VOD (video on demand) are usually aggregated in a short period intensively and user preferences are fluctuated dynamically.
Moreover, the VOD content is updated frequently under the management of IPTV providers.
Thus, an accurate popularity prediction method and an effective cache system are vital because they affect the IPTV performance directly.
This paper proposed a new window-based popularity mechanism which automatically responds to the fluctuation of user interests and instantly adjusts the popularity of VOD.
Further, we applied our method to a commercial IPTV system and the results illustrated that our mechanism indeed offers a significant improvement.
