High Quality Content by WIKIPEDIA articles! Continuous Media Markup Language (CMML) is to audio or video what HTML is to text. CMML is essentially a timed text codec. It allows to structure a time-continuously sampled data file by dividing it into temporal sections (so-called clips), and provides these clips with some additional information. This information is HTML-like and is essentially a textual representation of the audio or video file. CMML enables textual searches on these otherwise binary files.
