Digital television (TV) broadcasting offers the user an opportunity to watch higher quality television channels, compared with analog television. The opportunity to watch the television broadcasting of a higher quality is an important criterion for the users who are choosing any of TV service. However, unlike the service providers, the users evaluate television service in terms of their own parameters for Quality of Experience (QoE): the quality of television channel broadcasting and the television channel zapping time during the process of TV channel change. In this case, for the user which chooses digital television instead of the analog television, the implementation of the longer channel change process and its duration negatively affects the user's perception of the attractiveness of service and his individual needs. The duration of TV channel change process is known as the TV channel zapping time. Due to this, it is important for the television service provider to analyze the impact of the channel change process and the channel zapping time to the QoE of digital TV service. As nowadays the digital terrestrial/ handheld television (DVB-T/H) is most common TV service and digital IP (Internet Protocol) television (known as IPTV) is considered as the most promising contender for the digital terrestrial/ handheld television, so the task of this paper is to analyze and compare the QoE for DVB-T/H and IPTV services by the TV channel change process and its duration.
