| 释义 | fragmented MP4fragmented MP4A streaming media format based on Part 12 of the MPEG-4 standard (ISO base media file format). Unlike the older MPEG-2 Transport Stream (M2TS) format, which is used in Apple's streaming platform, fragmented MP4 (fMP4) does not multiplex the audio and video together. The streams can be stored separately, and the total combinations of files necessary to support multiple bit rates, resolutions and languages is dramatically lower than M2TS. Microsoft's Smooth Streaming was the first streaming platform to adopt fMP4, and Adobe's HTTP Dynamic Streaming followed suit. See MPEG-2 TS, Smooth Streaming and HTTP Dynamic Streaming. |
