    摘要： Provided is a data reception error reduction system and method in acoustic communication in audible frequency range, and an apparatus applied thereto. The data reception error reduction system in the acoustic communication in audible frequency range may be configured to reduce a data reception error in a receiver by taking into consideration that a sound signal is noisy and is significantly affected by a change in the ambient environment when the acoustic communication is performed in the audio frequency band through modification of an audio signal or adding of a predetermined signal to an audio signal. Accordingly, the data reception error may be reduced in the receiver even in an environment where a sound signal is noisy and is significantly affected by a change in the ambient environment, and reliability of data transmission may increase.

    摘要： Provided is a system and method for a local area broadcast service, and a wireless transmission apparatus applied to them. In the system, contents to be broadcasted in a predetermined local area are transmitted from a broadcast server to a wireless transmission apparatus through a wired network based on an Internet Protocol and the contents are then broadcasted from the wireless transmission apparatus to one or more user terminal devices. Therefore, according to the present invention, a server of a wired network can easily provide particular contents for each particular local area to one or more user terminal devices in the local area. Moreover, it is possible to reduce the load of the server, when the server provides multiple types of contents or provides contents to a plurality of user terminal devices.

    摘要： Disclosed is a multicast system and a multicast method using a shortened address and an apparatus applied to the same. The multicast system using the shortened address according to the present disclosure has a address configuration for supporting a multicast in an IEEE 802.15.4 MAC (Medium Access Control) layer. Accordingly, when a device processes a multicast through an address configuration of the MAC layer, the device receives the multicast through a simple scheduling such as receiving a beacon signal of a coordinator device only when there is a broadcast of a group including the device. As a result, the device can efficiently perform the multicast in a power managing process or a power processing process.

    摘要： Disclosed is a system and a method for minimizing signal interference for a broadcasting and communication convergence section within a local area, and an apparatus applied to the same. The system has a construction of mounting a plurality of multi RF (Radio Frequency) channels within a local area wireless communication apparatus located in a local area and minimizing signal interference between mutually adjacent RF channels within the local area wireless communication apparatus in a standard for providing a broadcasting and communication convergence service. Accordingly, it is possible to remove the mutual channel effects affecting a communication signal without signal interference for adjacent channels due to a broadcasting signal and it is not necessary to enhance a filtering characteristic for the adjacent channels of a chipset, which corresponds to a broadcasting and communication convergence standard structure in a local area, so that there is an advantage of reducing network investment costs.
