In IPTV systems, Quality of Experience (QoE) is very critical factor for end-user satisfaction. Existing and future IPTV systems will offer a large number of channels to users. The most important factors that affects to QoE in IPTV systems are channel zapping and channel selection problems. Generally, the channel zapping time depends on several parameters like Internet Group Membership Protocol (IGMP) command processing time, network delay time, IPTV consumer device processing delay time, jitter buffer delay time, MPEG decoder time and Conditional Access/Digital Rights Management (CA/DRM) delay time. In this paper, we present an analysis of channel change delay in IPTV systems and we propose a new approach based on channel-based peer selection, called CBPS where the most suitable peer to construct peer-to-peer (P2P) communication will be discovered from a look-up table in the central server. © 2011 IEEE.en10.1109/ICAICT.2011.6111020info:eu-repo/semantics/closedAccessChannel zapping timesInternet Protocol TV (IPTV)Peer-to-Peer (P2P) transmissionQuality of Experience (QoE)Buffer delayCentral serversChannel changeChannel selectionChannel switchingChannel zappingChannel zapping timeConditional accessConsumer devicesConsumer electronics marketsCritical factorsDelay TimeEnd usersGroup membership protocolsInternet protocol tvInternet Protocol TV (IPTV)IPTV systemsKey factorsLook up tableMPEG decoderNetwork delaysPeer selectionPeer to peerPeer-to-peer communicationsProcessing TimeQuality of Experience (QoE)Quality of experiencesRights managementCommunicationConsumer electronicsDistributed computer systemsInformation technologyInternetInternet protocolsMotion Picture Experts Group standardsPeer to peer networksQuality of serviceTable lookupTelevision broadcastingIPTVConference Object2-s2.0-84855977282
