The new HEVC/H.265 coding standard can bring many benefits to the broadcast video industry, reducing bit rates by approximately 50% when compared to an equivalent quality video stream encoded using H.264 thus enabling more channels or higher quality video delivery over the same infrastructure. It is particularly relevant for 4K UltraHD transmission which requires a much higher stream capacity. These improvements are achieved at the penalty of much higher computation complexity, with up to four general purpose server class processors required to perform a 4K 60fps software-based broadcast quality HEVC encoding in real time. This means adding HEVC functionality by software only to existing systems is a particular problem: the choice is between severely limiting capability or requiring much more hardware.
