Abstract :
We propose a method for perception evaluation of synchronization mismatch for large ultra high resolution tiled displays. The results from this work can help during design of low cost tiled display systems which utilize distributed synchronization mechanisms for image display. We describe a method for creation of synchronization mismatch measurement test video set for various tile configurations for various inter-panel synchronization mismatch values. The method supports synchronization mismatch perceptual evaluation for tiled display with or without tile bezels. The proposed method creates a higher frame rate video from an original video for playback using a typical video player for subjective quality evaluation. The proposed method reuses and adapts established approaches for subjective quality evaluation based on ITU-R recommendations.
