The correlation between the MOS values and IPTV channel zapping times during the regression analysis was determined using the fifth and third degree polynomials (Fig.
So it is important to determine the tolerance's limit according to the IPTV channel zapping time, in what the user's reaction to the perceived quality of service is in a significant change and the change's suddenness of this reaction.
The analysis of the investigations' results showed that the sharpness of the change of the user's reactions to the IPTV channel zapping time and critical thresholds of this parameter are different using the different methods for the TV channel change.
After the analysis of the experimental data, it was found that the standard deviation of the TV channel zapping time was [[sigma].sub.1] = 0.52, when TV channel was selected sequentially.
where [T.sub.zapping] is IPTV channel zapping time; [sigma] is the standard deviation of the experimental data of IPTV channel zapping time.
In summary, it is clear that zapping is a fairly widespread phenomenon and potentially of considerable concern to advertisers.
Despite the fact that zapping is a universal phenomenon, little work has been done on how to increase advertising effectiveness under habitual zapping behavior.
First, we try to resolve the conflict in the literature regarding the effect of zapping on advertising effectiveness.
Since the term zapping has been used to refer to somewhat different viewer behavior by different authors, a clear operational definition of the term is required for this study.
In this study, we focused on the impact of zapping behavior on advertising effectiveness measured by the percentage of successful brand recall, as well as the best position to place an advertisement during a commercial break.
A new IPTV channel zapping scheme for EPON // Proceedings of ICUFN 2009.--P.
Little is known about the effect of zapping on advertising effectiveness due to the sparseness of research studies linking the two variables.
Greene's (1988) contribution is that it relates zapping behavior to advertising effectiveness.
has suggested that zapping is indeed a potentially significant problem for advertisers (see Kneale, 19&8).
Among its interesting findings, the Percy study noted that while a new specialty commercial, such as the Pepsi ad featuring singer Michael Jackson at the 1988 Grammy music awards, showed a relatively low audience loss (about 2 percent), certain ads, aired during competing popular sports events, showed staggering losses of as much as 43 to 53 percent due to zapping. The study concludes that a "commercial rating" is typically much lower than that of a show.
