“…This is the delay between the time the user switches to a particular TV channel and the time when the content is displayed on the TV screen. This delay can add up to 2 s or more [1], and its main culprits are stream synchronisation and buffering of the media streams [2][3][4]. It is known that this figure should be below 430 ms to guarantee an acceptable user experience [5], so this is a major concern for IPTV service providers that want to compete in this market.…”

“…T system indicates the time for video buffering and reordering, T process indicates the time to transmit the remote control command and to process the channel change command, T decode indicates the time to decode by the video decoder in the host, and T IGMP indicates the IGMP leave/join process time. The parameters and the value for modeling are assumed in Table I according to [5,7]. EIGMP is highly related to reducing the IGMP leave/join process time.…”

Abstract:The extended Internet group management protocol (EIGMP) is a method which allows simultaneous reception of channel streams being broadcasted for other users in shared networks. Recently, implementation of EIGMP in gigabit Ethernet passive optical network (GEPON) was suggested to reduce the channel change response time (CCRT) especially for Internet protocol television (IPTV) systems. In this paper, we extend EIGMP in gigabit-capable PON (GPON) with a cross-layer approach. With the proposed method, the CCRT in GPON can be reduced by up to 10.3% in comparison with that of traditional IPTV systems.

Abstract-Zapping-delay is an important factor contributing to the quality-of-experience (QoE) of any multimedia service; the longer the zapping-delay, the worse is the QoE. Therefore, for a good QoE, it is necessary to bind zapping-delay within acceptable bounds. Coded video uses a motion compensated prediction structure that contributes to the zapping-delay. In DVB-H, zapping-delay is further increased because of the time-sliced burst transmission architecture. Hence, any attempt to bind zapping-delay must consider both the prediction structure of coded video, as well as the time-sliced transmission architecture of DVB-H. This paper analyzes prediction structure of video as binary relations generating a prediction graph. Reachability concepts of graph theory are then applied to construct binary valued indicator functions. These indicator functions inform about the reception, decoding, and play-out states of each access-unit in the video sequences. zapping-delay is studied by dissecting the components that it is composed off. Conditions for minimizing each of them individually, while the final zapping-delay does not exceed a known bound, is found. Emphasis is also laid on gradual quality enhancement after the display of the new program has started.Index Terms-Broadcast channels, DVB-H, H.264/AVC, video processing, zapping-delay.
