Adaptive Video Quality Model for UHD Video Broadcasting Using the Principle of Inclusion

Abstract

In this study, an adaptive video quality algorithm is developed for Ultra High Definition (UHD) video broadcasting through Digital Video Broadcasting by Satellite 2nd Generation (DVB-S2), where three conditions are responsible for enhancing or reducing the quality of a video signal received by the DVB-S2 Set-Top-Box (STB). The conditions are: Coverage area, Distance between transmitter and receiver and Separation distance. These conditions are responsible for the required Signal to Noise Ratio (SNR), resultant Bit Error Rate (BER) and the overall capacity of the system. Based on these conditions, received parameters of an HD or UHD video vary; and the quality viewed by the user changes. Therefore, in this study, we have proposed an algorithm based on the future broadcast scenario where the broadcasters will be dealing with simulcasting of multiple video standards of HD and UHD, varying in resolution, frame rate, codec and more. This algorithm is developed using the Principle of Inclusion.
