The large‐scale streaming of videos on demand, as exemplified by Netflix, Amazon, and YouTube, is a remarkable modern engineering achievement that embodies significant advances in such fields as video compression and communications, digital networks, high‐speed computation, and display technologies. Yet even today, there remain significant challenges in providing the highest quality compressed digital video content to the consumer. We consider two of the main issues. The first is source inspection, whereby the intrinsic quality and possible impairments of source videos of interest are determined. The second is that of balancing the tradeoffs that can occur between video compression and rebuffering effects. We describe recent human studies that we have conducted on these problems and the types of automatic prediction models that we have been developing.
