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.
