摘要： Disclosed is a device for filtering out a null packet in a data stream for example an MPEG-2 TS (Transport Stream) to avoid bandwidth waste when it is transmitted to a backbone network. The device includes a plurality of receiving interfaces, a filter unit, and a controller. The receiving interfaces receive parallel data, such as DVB-ASI (Digital Video Broadcasting-Asynchronous Serial Interface) inputs as channel-by-channel MPEG-2 data. The filter unit counts the respective numbers of data packets and non-data packets of the data input from the receiving interfaces and filters a null packet in the data. A network transmission unit transmits the filtered data to a backbone network. The controller calculates a bit rate based on both of the count numbers received from the filter unit.

摘要： A system for integrating broadcast and communication technologies includes an optical-line terminal (OLT), a optical-network unit (ONU) and a user gateway, wherein a broadcast signal is processed on the basis of time division multiplexing (TDM) such that the quality of a broadcast service can be ensured. The ONU separates the optical signal transmitted from the OLT into the broadcast signal and the communication signal, processes upstream information transmitted from a user, and optically transmits the broadcast signal and the communication signal selected on a user-by-user basis, on the basis of a time slot. The user gateway opto-electrically converts a time slot-based optical signal transmitted from the ONU, separates the time slot-based optical signal into individual signals, distributes the individual signals on a service-by-service basis, and optically transmits the upstream information from the user to the ONU.
