WHAT is entertainment software in application software?
Its very simple, just remember in the present day we all are having the entrtainment through the Internet, and various applications are made for the certain purpose. The e…ntertainment application can be divided into two types: a) movie/video on demand b) interactive television a) Movie/Video on demand: These systems allow users to select and watch video on demand. IPTV (Internet Protocol Television) technology is used to bring video on demand to televisions and personal computers A collection of digitized movies/ videos are stored on the server. The subscriber terminal comprises a conventional television with a setup box that conveys the user interactions to the server. Through a suitable menu, the subscriber is able to browse through the set of movies/videos available and initiate the showing of a selected movie. This means that the server must be capable of playing out simultaneously a large number of video streams depending on the number of subscribers currently watching the movie. It may also happen that some subscribers may demand for the same movie. Therefore, the information flows from the server must be extremely high since it must support not just the transmission of a large number of different movies, but also multiple copies of each movie. Practically, this is very challenging and implementation cost will be very high because the cost of the server is directly proportional to the information flow rate from it. In situations where several subscribers request for the same movie within a short time interval between each request, an alternative approach can be used. In this approach, requests for a particular movie are not played out immediately but instead are queued until the start of the next play out time of that movie. Hence, all the requests for the same movie which are made during the period up to the next play out time are satisfied simultaneously by the server by just playing a single video stream. This approach is known as near movie-on-demand or N-MOD. But in this case, the viewer cannot control the play out of the movie. b) Interactive television: When the viewer and broadcaster can communicate with each other, usually in real time then it is known as Interactive TV. Normal TV flows in a one way path, from the broadcaster to the viewer, however interactive TV, usually includes a digital modem or other form of hardware that can return information or data from the viewer back to the broadcaster which can include either the cable operator, satellite TV operator or broadcast company.
