Dear Dr.M.Leeladharan,
DSpace is able to store digital objects and allow their discovery and download. At the moment there are no tools to play/visualize them.
The module allows to transcode the most popular audio/video formats into a format (FLV, MP4) and encoding appropriate to the adopted media server. The module takes care of the registration of the transcoded file on the media server, local or remote, if necessary by creating different streams at increasing bitrates, segmenting and diversifying the channels (audio, video, subtitles) to enable adaptive streaming. The adaptive streaming allows the maximum reduction in the use of bandwidth, always providing each user the best possible resolution of the audio / video stream based on the device in use (supported resolution) and on the available connection speed. By varying the connection speed during the playback of the stream, the system is able to consequently alter the stream so as to improve the quality of vision or the playback fluidity in the case of the connection quality decrease.
Best regards,
Susanna
