New integral quality of TV service criterion construction based on quality of experience statistical estimation

With the rapid development of DTV methods and tools, preconditions are being made for the creation and implementation of new services. New services can be spread using various technologies, such as Web and DVB. However, the qualitative parameters of services for individual technologies are different. As it is known, the qualitative parameters for digital TV are regulated by the ITU and ETSI recommendations. However, rapid development of different technologies integration leads to creation of common criterions for quality of service and metrics for their evaluation. It is known that the qualitative parameters for audio/video content consist of two components - objective and subjective. DTV operators are faced with a difficult task - how to match the requirements of broadcast parameters to ensure the required quality of experience (QoE) to the end user optimizing transmission parameters related to quality of service (QoS). The aim of this work is to create an integral and statistically confident subjective criterion representing QoE, which depends on any set of objective parameters related with different technologies and representing QoS.
