Eliminate the Redundancy Information from the Video Presentation Slides

Video streaming become a pivotal role in our daily lives in entertainment, surveillance, teleconference, seminars, and education. Distance education or online learning is the most growing sector that start using video streaming. The video that represents the lecture contents will be multicast to a group of students. The presentation slides will be formulated to a sequence of video frames. Where the sequence of frames is fragment into many segments. Each segment is representing a number of redundancy frames that belong to the same slide. Streaming the redundancy frames will load the traffic on the Internet, due to the size of video data that are transmitted over limited bandwidth and especially during the peak hours. In this study, the combination of temporal and spatial adaptation to the video streaming are considered to reduce the data traffic. Temporal adaptation is applied, to drop a number of redundancy frames from the segment that represent each slide. While spatial adaptation is applied to reduce the data from the selective frames that will be streamed. Experimental results show that, the proposed technique significantly reduce the streaming length and their data size. Different parameters are applied to map the streaming data to the network bandwidth, while the video that represent the presentation slides will be played with a satisfactory quality.
