IPTV Zapping Overview
IGMP and Channel Zapping
IGMP is a signaling protocol that enables each STB to obtain only the programming that the viewer is
interested in watching, thus conserving bandwidth in the access network.
STBs use the IGMP to change channels, by leaving and joining multicast groups representing channels.
Key to IPTV QoE, is how fast and reliably end users can change TV channels, also known as "channel
zapping".
Essentially it is calculated as the time taken between sending a channel leave request and receiving the
first video data of the new video stream.
Refer to DSL Forum TR-126 Triple Play Quality of Experience (QoE) requirements for
more info.
