Adaptive robust video broadcast via satellite [PDF]

Multimedia Tools and Applications, 2016
With increasing demand for multimedia content over channels with limited bandwidth and heavy packet losses, higher coding efficiency and stronger error resiliency is required more than ever before. Both the coding efficiency and error resiliency are two opposing processes that require appropriate balancing. On the source encoding side the video encoder

Motion Detection in Satellite Video

Journal of Remote Sensing & GIS, 2017
In view of the problem of satellite video motion detection, a background subtraction method of combining global motion compensation and local dynamic updating is proposed. In the first instance, the improved ViBE model method is used to establish the background model in the middle frame. The background model has one more dynamic update factor. Secondly,

Video Streaming Transfer in a Smart Satellite Mobile Environment [PDF]

International Journal of Digital Multimedia Broadcasting, 2009
Transportation media are becoming “smart spaces”, where sophisticated services are offered to the passengers. We concentrate on video streaming provided on buses that move in urban, suburban, or highway environments. A content provider utilizes a DVB-S2 satellite link for transmitting video streams to a bus, where they are relayed to passengers ...
