  • ADAPTIVE MEDIA STREAMING METHOD AND APPARATUS ACCORDING TO DECODING PERFORMANCE
    Publication number: 20180131741
    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.
