Abstract: A method and apparatus for streaming media without installing a plug-in in a web browser are provided. When a JavaScript decoder is used to stream media without installing a plug-in, it is difficult to support decoding of high framerate and high resolution video due to the limitations of JavaScript. When streaming media using a video element of HTML5 without installing a plug-in, a compatibility issue with a conventional video capturing apparatus using RTSP/RTP and an initial delay problem due to a container of MPEG-DASH are inherent. The present disclosure presents an adaptive media streaming method and apparatus capable of performing streaming of high framerate and high resolution video without an initial delay and compatibility issues by addressing these drawbacks.

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.

Abstract: A media playback apparatus for playing media on a web browser may be provided. The media playback apparatus may include: a receiving unit that receives media data generated in a media service apparatus; a first media restoring unit that decodes the received media data by a first decoder embedded in the web browser; a second media restoring unit that decodes the received media data by a second decoder written in a script, which is parsed by the web browser; a user interface configured to receive a user command; and a decoding controller configured to control the first media restoring unit to decode the received media data in response to the user command corresponding to a playback command and control the second media restoring unit to decode the received media data in response to the user command corresponding to a seek command.
