Blu-ray is a digital video disc format that was introduced in 2006 as a successor to the DVD format. It offers higher storage capacity and better video and audio quality than DVD. HEVC (High Efficiency Video Coding) is a video compression standard that was developed to provide better compression efficiency and video quality than H.264/AVC. HEVC is widely used for 4K and UHD video content, but it is also used for HD video to provide a more efficient compression.
