APPARATUS AND METHOD FOR PROVIDING FREQUENCY HOPPING SCHEME IN BROADCAST COMMUNICATION SYSTEM.

摘要

An apparatus and a method for using a frequency hopping scheme in a broadcast communication system are provided. A method for transmitting a broadcast signal via at least two frequency bands by a transmission end device in the broadcast communication system includes determining a frequency hopping pattern for providing a broadcast service and transmitting the same; transmitting control information via a first frame after a frequency is changed according to the frequency hopping pattern; and transmitting broadcast data for the broadcast service via a frame transmitted after the first frame. An apparatus and a method for using a frequency hopping scheme in a broadcast communication system are provided. A method for transmitting a broadcast signal via at least two frequency bands by a transmission end device in the broadcast communication system includes determining a frequency hopping pattern for providing a broadcast service and transmitting the same; transmitting control information via a first frame after a frequency is changed according to the frequency hopping pattern; and transmitting broadcast data for the broadcast service via a frame transmitted after the first frame. Disclosed is a seat mounted airbag apparatus, which is deployed from a side cushion of a seat to protect a lateral side of a passenger and pushes a side foam pad toward the passenger to surround the lateral side of the passenger with the side foam pad, thereby improving the safety performance. The seat mounted side airbag apparatus includes an inflator installed in a seat frame provided in a receiving section of a foam pad formed at a lateral side of a vehicle seat and a cushion connected to the inflator. When the cushion is expanded, the foam pad is divided into an inner pad and an outer pad and the inner pad pushes the passenger so that the passenger is moved away from an impact point.
