“…However, this method did not solve the zapping delay problem because if a subscriber does not switch to the adjacent channel, it forfeits the purpose. Lee et al [22] improved on this method by adding channel popularity with adjacent-based prefetching. is method is used in prefetching the contents of adjacent channels before they are requested.…”

“…After waiting for the IPTV content of the requested channel to be delivered, the STB waits for a decodable frame, called an Intra-coded frame (I-frame). e requested channel is ready to be displayed on the TV set once the requested channel is delivered to the STB of the subscriber [22,29].…”

e Internet protocol television brought seamless potential that has revolutionized the media and telecommunication industries by providing a platform for transmitting digitized television services. However, zapping delay is a critical factor that affects the quality of experience in the Internet protocol television. is problem is intrinsically caused by command processing time, network delay, jitter, buffer delay, and video decoding delay. e overarching objective of this paper is to use a hybrid delivery method that agglutinates multicast-and unicast-enabled services over a converged network to minimize zapping delay to the bare minimum. e hybrid method will deliver Internet protocol television channels to subscribers using the unicast stream coupled with differentiated service quality of experience when zapping delay is greater than 0.43 s. is aids a faster transmission by sending a join message to the multicast stream at the service provider zone to acquire the requested channel. e hybrid method reported in this paper is benchmarked with the state-of-the-art multicast stream and unicast stream methods. Results show that the hybrid method has an excellent performance by lowering point-to-point queuing delay, end-to-end packet delay, and packet variation and increasing throughput rate.
