Abstract:
A method of switching resolution is provided. The method includes: in playing audio and/or video using DASH, acquiring a media presentation description (MPD) file and obtaining resolution information through parsing the MPD file; during the playing of the audio and/or video, periodically determining a currently secure downloading speed according to a preset time interval and determining whether a resolution switching for the audio and/or video currently being played is required according to the secure downloading speed and the resolution information; and in accordance with a determination that the resolution switching is required, determining a switching time point according to an elapsed duration of a currently playing segment and a preset secure buffering duration and performing resolution switching at the switching time point.
