摘要： A method for measuring an Internet Protocol Television (IPTV) channel zapping delay to be implemented using a system that includes a scheduling unit, a remote controller, a stream providing unit, a set-top box, and a packet analyzing unit, said method comprising: a) configuring the scheduling unit to control the remote controller to transmit a channel change signal to the set-top box, whereby the set-top box initiates communication of a plurality of packets with the stream providing unit; b) configuring the packet analyzing unit to capture the packets communicated between the set-top box and the stream providing unit; and c) configuring the packet analyzing unit to compute an IPTV channel zapping delay corresponding to the channel change signal on the basis of the packets captured in step b). A system for measuring an IPTV channel zapping delay is also disclosed.
