Abstract: A method, an apparatus, and a system for providing additional information through a digital media content are provided. The method includes: detecting an item selected by a user selection when the user selection is sensed in a media content that is being reproduced; judging whether the user selection is a first selection for primarily selecting the item or a second selection for secondarily selecting the item in a set time after the item is primarily selected; and highlighting at least a portion of the item according to a set display format according to whether or not additional information linked to the item is present in the case in which the user selection is the first selection and displaying the additional information linked to the item in the case in which the user selection is the second selection.

Abstract: An adaptive multi-view streaming processing method and apparatus for a multi-view stream is disclosed. Specifically, disclosed herein is a method and apparatus for adaptively processing or transmitting adaptive streaming by reflecting network states and changes in transmission environments in a multi-view streaming service environment where several or more multiple videos are simultaneously transmitted at an arbitrary moment. An adaptive streaming processing method for a multi-view stream may comprise selecting and downloading an i-th segment of a main view stream with a first quality level, inferring a size of an i-th segment of downloadable neighboring view streams based on a download time and transfer rate of the i-th segment of the main view stream, and selecting a second quality level corresponding to the inferred size of the i-th segment of the neighboring view streams and downloading the i-th segment of the neighboring view streams based on the selected second quality level.
