Abstract: A media playback apparatus and a method including a system for preventing a playback delay are provided. The media playback apparatus may include a delay detecting module to detect a playback delay. The playback delay detection may determine a delay caused by a network, decoding and rendering through a single measurement. When the playback delay occurs, it may be possible to eliminate the playback delay by requesting that a server provide media data having a changed profile. Since the playback delay can be determined through a single measurement of a plurality of playback delay factors, it may be possible to simply and stably perform media playback in a manner suitable for a non-plug-in environment.
