Differences between HD- and HDX
Contents
Comparison Article[edit]
High Definition (HD) refers to video that has a higher resolution than standard-definition (SD) video. Generally, any video with 720 or more horizontal lines is considered high definition.[1] Common HD resolutions are 1280x720 pixels (720p) and 1920x1080 pixels (1080p).[2]
HDX is a term used in several contexts to denote a higher or more advanced version of HD. Its meaning varies depending on the product or service.
In video streaming, HDX is a format offered by the Vudu service, providing 1080p resolution with enhanced audio quality.[3] Amazon also used the HDX branding for its Kindle Fire tablets, with HDX models featuring higher screen resolutions and faster processors than standard HD models.[4][5] In a different field, Citrix uses HDX as a name for its suite of technologies designed to optimize the delivery of virtual desktops and applications.
HD vs. HDX in Video Streaming[edit]
The streaming service Vudu uses the term HDX to describe its premium high-definition streaming format.[3] While standard HD on the platform can vary in resolution, HDX is specifically 1080p at 24 frames per second.[1] Vudu's HDX format also incorporates "TruFilm" technology, a set of processing techniques designed to improve picture quality by preserving film grain and enhancing details in dark scenes. Due to the higher quality, HDX movie files are larger than standard HD files and may require a longer download or buffering time.
