Popular channel concentration schemes for efficient channel navigation in internet protocol televisions

Internet Protocol Television (IPTV) is becoming increasingly popular as an emerging Internet application due to its variety of contents and services. However, hundreds of IPTV channels make it difficult to find one¿s desired channel. To relieve this problem, this paper presents a popular channel concentration scheme for efficient channel navigation in IPTV. Based on the property that TV channel selections concentrate on several frequently selected channels, the proposed scheme reorganizes channel sequences by clustering popular channels. Specifically, channels are rearranged in a frequency interleaved way to minimize the seek distance. Simulation studies show that the proposed scheme reduces the seek time of IPTV channel navigation significantly when up-down channel selection interfaces are used.
