Measuring the incidence of packet loss on video quality in Digital Television

Digital Television (DTV) is the communications service with higher penetration in society. Video content reaches households through different transmission channels, which add noise to transmitted signal, leading to bit errors in the received signal. DTV standards include error correction codes, which can correct bit errors at the receiver side. However, if these errors are large enough, original signal would not be recovered and some video packets will be lost. This will result in a degradation of received video quality. In this paper we discuss the incidence of packet loss on the video quality perceived by the DTV viewer and we present a novel model to measure video quality in DTV.
