摘要： A digital broadcasting system includes an authoring apparatus and a transmission apparatus. The authoring apparatus generates event information, which defines an event message that should be transmitted immediately after an operator's instruction to transmit the event message is received, and adds the event information to a content. The authoring apparatus then extracts the event information from the content by referring to tag information and transfers the extracted event information to the transmission apparatus. The transmission apparatus stores the event message defined by the event information transferred from the authoring apparatus. According to an operator's instruction to transmit the event message, the transmission apparatus issues the event message, and multiplexes and transmits the issued event message and the content.

摘要： A packet filtering apparatus selectively outputs packets among a plurality of inputted packets. A plurality of conditions are stored, with each condition being specified by a partial data position that indicates a position of a data part of a packet, comparison data to which the data part is to be compared, and a comparison criterion for comparing the data part and comparison data. Different conditions contain different comparison criteria. When filtering packets, a condition in one of the stored conditions is selected, and a data part of an inputted packet is compared with the comparison data of the selected condition according to the comparison criterion in the selected condition. Packets are selectively outputted depending on the result of the comparison.

摘要： A data stream selection/output apparatus that selects and outputs a data stream composed of sequentially obtained data. The data stream selection/output apparatus obtains timing information indicating a time at which a first data stream being output should be switched to a second data stream. The data stream selection/output apparatus, in a time period including the time indicated by the timing information, scans the first and second data streams to detect a first boundary between data blocks of the first data stream and a second boundary between data blocks of the second data stream, where the data blocks conform to a transmission protocol higher than Transport Layer of OSI Reference Model. The data stream selection/output apparatus then stops outputting the first data stream at the first block boundary and starts outputting the second data stream at the second block boundary.
