In last couple of years, there has been good amount of work related to the video-on-demand (VOD) services. Video-on-Demand refers to provide a video to a user whenever he/she desires to watch it. Like VOD, there are other similar services such as movie-on-demand, news-on-demand, and audio-on-demand. There have been many schemes, called video broadcasting schemes that can help to provide VOD services. These schemes include staircase, conservative staircase, generalized conservative staircase, harmonic broadcasting schemes. In this talk, basics of VOD will be discussed followed by some important broadcasting schemes.
Generally for applying a broadcasting scheme to a video, the video size should be known in the very beginning otherwise these broadcasting schemes cannot be applied. For live videos such as cricket match, their ending time and hence their size is not known in the beginning. This implies that the existing broadcasting schemes in their original form cannot be applied to live videos. How some existing schemes can be tailored so that they can be applied to live videos will also be discussed.
