Abstract:
1. A method for allocating channel bandwidths in a wireless Internet Protocol TeleVision (IPTV) system, the method comprising: receiving an additional service offering request from a user in a channel saturation state that exceeds a number of users who can use the service; measuring remaining execution times until a service of each terminal that is currently receiving the service is terminated; setting a minimum of the measured remaining execution times to a unit time; calculating a securable channel bandwidth per the unit time with respect to each terminal that is currently receiving the service; summing the securable channel bandwidths per the unit time for all terminals that are currently receiving the service; and allocating the requested channel bandwidth in order to provide the additional service, if a summation of the securable channel bandwidths per the unit time is at least equal to the channel bandwidth required to provide the additional service.
