3 Terms and definitions

GB/T 9390, GB/T 19391, GB/T 34966.2 and GB/T 34966.3 defined by the following terms and definitions apply to this file. 3.1 Data Server dataserver Get data source data and calculation processing, generate enhanced information, and as HTTP/RSTP client to the broadcast server to send the seal Installed data server. Note 1. A data server in the simplest configuration is an application running on a computer that calculates, encapsulates, and forwards data from a data source Broadcast server. The specific data package format see GB/T 34966.3. The data server can support the forwarding of data from the virtual reference station to the server The virtual reference station for information is understood as a single data source. Note 2. In the distribution system, the data source, which is the source of the data, connects to the data server to provide it with a continuous stream of raw data. Each single data The source corresponds to and provides information data for a specific area, and must have a unique identifier in an advertisement server, that is, mount point. The attribute description parameters for the data source are compiled and stored in the source information table maintained by the advertisement server, including the data format used by the advertisement server, Location coordinates and other information. Related concepts of source information table see GB/T 34966.2. 3.2 Broadcast server broadcastserver Broadcasting system to receive data, organize and broadcast the server. Note. As the core server of HTTP/RSTP in the advertisement network, the advertisement server receives the message from the data server or the user node on a listening port Out of the HTTP/RTSP subset of the request message and make a decision based on the request response. The broadcast server accepts the data server requests to receive uploads According to and finishing, accept user node request and send data source information or enhanced information data to the user node. The source information table is maintained on the broadcast server.
