METHOD AND APPARATUS FOR ALLOCATING CHANNEL BANDWIDTH IN WIRELESS INTERNET PROTOCOL TELEVISION SYSTEM

摘要

PURPOSE: A method and an apparatus for allocating a channel bandwidth in a wireless internet protocol television system are provided to allocate an additional band for an additional user while securing the QoS of existing users by using a dynamic band allocation technique depending on an invention. CONSTITUTION: In a unit time setup step, a remaining execution time is measured until a service of the terminals which receive a current service. In a channel band calculation step, a channel band which can be secured per unit time of each terminal which receives a current service. A time information reception unit(601) receives data non-reception execution time information which is an executable time through only the data stored at a buffer(651) of the terminal which receives a current service.
