Service Description Table (SDT) is a metadata table used in Digital Video Broadcasting systems to describe the television, radio or other services contained in MPEG transport streams provided by the system. The purpose and format of the table is defined in ETSI EN 300 468: Specification for Service Information (SI) in DVB systems. The SDT provides the following information about each service: Further optional information may be provided about each service, such as the name of the service, the name of the broadcaster responsible for the service, service availability or service authority url.

dbo:abstract
  • Die Service Description Table (SDT; deutsch Programmbeschreibungstabelle) ist eine Tabelle, welche Informationen über die ausgesendeten Programme (Services) beim digitalen Fernsehen (DVB) enthält. Daten aus der SDT werden für die Darstellung des Programmnamens genutzt. Sie ist Teil der DVB-SI und spezifiziert nach ETSI EN 300 468. Die SDT enthält Informationen über Programme (Services) im empfangenen und ggf. zusätzlich auch in weiteren Transportströmen. Sie wird in Paketen mit der PID 17 ausgesendet. (de)
  • Service Description Table (SDT) is a metadata table used in Digital Video Broadcasting systems to describe the television, radio or other services contained in MPEG transport streams provided by the system. The purpose and format of the table is defined in ETSI EN 300 468: Specification for Service Information (SI) in DVB systems. An MPEG transport stream consists of a sequence of packets. SDTs are contained in packets identified by the packet ID (PID) 0x0011. Such packets may alternatively contain a Bouquet Association Table (BAT) or a Stuffing Table (ST). The type of information carried in the packet is identified using a table ID. The table ID 0x42 identifies the SDT providing information about services contained in the same transport stream as the SDT itself. The table ID 0x46 identifies SDTs providing information about services contained in other transport streams in the same network or system. The SDT provides the following information about each service: * the transport stream id. * the service id. * whether or not programme schedules are provided in the transport stream. * whether or not there is information about the current and next programmes. * the running status of the service (e.g. starting soon, paused, running or off-air). * whether or not the service is scrambled. Further optional information may be provided about each service, such as the name of the service, the name of the broadcaster responsible for the service, service availability or service authority url.

  • 服务描述表(Service Description Table,SDT)是DVB、ATSC、ISDB等数字电视制式中使用的元数据表。它不是MPEG2-TS协议的一部分,不属于PSI,而由各数字电视标准作为服务信息(Service Information)分别定义。 MPEG2的传输流由传输流分组(TS Packet)组成。传输SDT的分组的PID为0x0011。SDT描述关于当前TS中所传输的服务的信息,对应的Table ID为0x42。 以DVB的SDT为例,它包含以下信息: * 传输流ID(TS ID) * 各服务ID(Service ID) * 该传输流中是否携带节目表信息 * 该传输流中是否携带当前节目和下一节目的信息 * 服务的运行状态信息(例如即将开播、已暂停、正在播放、已结束) * 特定服务的内容是否有加密 此外SDT还可包含服务名称、电视网络名称等可选信息。 (zh)
