Zero-latency scheduling scheme for broadcasting popular movies

In the real world, the viewers may want to have an ability to choose a desired video from some interested videos by scanning the first few minutes of these videos. Obviously, a broadcasting method, which allows subscribers buffering the data of the first few minutes of all popular videos, could provide this service without the startup latency. Fortunately, the capacity of harddisk or flash memory will increase and prices will become more affordable, enough to support the space needed to save such a large amount of data. In this work, we propose a zero-latency scheduling scheme (ZLSS) for broadcasting popular movies. The ZLSS method not only provides a zero-latency service for subscribers who buffering the data of the first few minutes of a video, but also provides a service with a shorter waiting time for subscribers who buffering nothing of the desired video. Compared with the previous method, the ZLSS method reduces the buffer requirement and the maximum waiting time by 10~50%.
