Nov 16, 2023 – CMCD segment prefetching

Common Media Client Data (CMCD) is an open specification created by the Consumer Technology Association. A media player can use it to send playback information to ​​Akamai​.

Your media player can include prefetching "hints" in CMCD metadata. This is supported for content that's segmented into individual objects, as well as byte ranges for prefetching parts of much larger media objects.

For more details on this feature, see Common Media Client Data.
