HEVC (H.265)
HEVC or High-Efficiency Video Coding is a video compression standard. It is also known as H.265 and MPEG-H Part 2. HEVC offers around twice the data compression ratio at a similar level of video quality, or considerably enhanced video quality at a similar bit rate in comparison to AVC (MPEG-4 Part 10 or H.264). Including 8K UHD, it supports resolutions up to 8192×4320. This advanced compression technology plays a pivotal role in optimizing live video streaming, allowing content providers to…

HD (High Definition)
HD (High Definition) video is video of higher resolution and quality compared to SD (Standard Definition). Even though there is no standardized definition for HD, usually any video image with substantially more than 480 horizontal lines is considered high definition. Normally, HD video has a resolution of 1280 x 720p whereas FHD (Full High Definition) video has 1920 x 1080p resolution. As the demand for quality content increases, the relevance of HD and FHD video becomes even more pronounced, particularly…

SD (Standard Definition)
SD (Standard Definition) video specifies the video and audio codecs and file format that allows users to watch video on several electronic devices built to SD standards. SD video supports different formats, including VC-1, H.264, MPEG-4 and MPEG-2. Standard definition has always been a 4:3 aspect ratio with a resolution of 640 × 480 pixels. While SD video provides a basic viewing experience, advancements in technology have shifted consumer preferences towards higher resolutions, such as HD (High Definition) and 4K.…
