The increasing use of digital video has put into perspective the storage requirements for a large number of video files. Different qualities of videos are available and each of these requires different storage areas. Different variety of devices having different pixel densities uses these files and accordingly has varying video processing capabilities. This paper presents a novel multimedia video encoding/decoding algorithm which is responsive to the device and responds to the device capabilities. This involves a light-weight, multi-layered approach whereby the video streams are divided into different layers and these are differentially loaded as per the quality requirements. This differential loading involves the progressive decoding algorithm for the video stream and henceforth a single file to be used vary the bit rate depending on several factors like the device processing capabilities, available memory, screen width and pixel density for different quality requirements. By in cooperating this method to WebRTC framework, the quality of video can be varied according to the network congestions. Our analysis reveals that this method is far more efficient than transcoding-on-air method which is used by multimedia servers which require special hardware support. For normal servers which use HTML5 for playback of video, this method reduces the total bandwidth required and saves a lot of storage space which results in smooth streaming over the web. This new approach makes the video files adaptive to the different devices on which they are running.
