    Abstract: A method of processing a digital television (DTV) signal in a DTV receiver, receiving a digital television signal including a plurality of extended text table (ETT) instances that appear in transport stream packets with common PID values, the ETT instances having common table ID values, each ETT instance comprising a section header and a message body, the section header containing a table identification (ID) extension field that serves to establish uniqueness of each ETT instance, the message body containing an extended text message (ETM) which provides detailed descriptions of a virtual channel or an event associated with each ETT instance, wherein the section header further contains a protocol version field indicating a protocol version and a current next indicator field; demodulating the digital television signal; and identifying at least one pertinent ETT instance from the plurality of ETT instances.

    Abstract translation: 一种在DTV接收机中处理数字电视(DTV)信号的方法,接收数字电视信号,该数字电视信号包括出现在具有公共PID值的传输流分组中的多个扩展文本表(ETT)实例,所述ETT实例具有共同的表ID 值,每个ETT实例包括部分标题和消息正文,该部分标题包含用于建立每个ETT实例的唯一性的表标识(ID)扩展字段,消息体包含扩展文本消息(ETM),其提供详细的 虚拟信道或与每个ETT实例相关联的事件的描述,其中所述部分报头还包含指示协议版本的协议版本字段和当前下一个指示符字段; 解调数字电视信号; 以及从所述多个ETT实例中识别至少一个相关的ETT实例。
