Abstract:
A virtual channel table for broadcasting protocol and a method for broadcasting by using the virtual channel table includes identification information identifying and permitting discrimination of active and inactive channels contained in the virtual channel table. At a receiver, the virtual channel table transmitted from the transmitting side is parsed, thereby determining whether the current received channel is an active or inactive channel.
Abstract:
A DTV receiver includes a receiver to receive 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 private indicator field indicating a private indicator a demodulator to demodulate the digital television signal and an identifier to identify at least one pertinent ETT instance from the plurality of ETT instances.

Abstract:
A broadcast signal reception method and a reception system are provided. The reception system includes a first processor, a second processor, and a storage medium. The first processor receives and processes a signaling table, the signaling table comprising first signaling information including access information of Non-Real-Time (NRT) service data and second signaling information including media object association information of the NRT service data. The second processor receives the NRT service data and processes a file including the received NRT service data based on the access information and the media object association information processed by the first processor. The storage medium stores the processed file of the NRT service data.
Abstract:
A method of receiving and processing a broadcast signal including a Non-Real Time (NRT) service and a broadcast receiver are disclosed herein. A method of processing a Non-Real Time (NRT) service in a broadcast receiver, the method comprises receiving and processing first signaling information including content access information and second signaling information including content detail information, receiving and processing third signaling information including content update information, receiving and storing a content including at least one file through NRT based on the first signaling information and the second signaling information, identifying update availability of the content based on the content update information included in the third signaling information, and receiving at least one file included in the content by accessing a File Delivery over Unidirectional Transport (FLUTE) session transmitting the content when the update is available.

Abstract:
According to one embodiment, a digital broadcasting system includes an RS (Reed-Solomon) encoder configured to encode mobile service data for FEC (Forward Error Correction) to build RS frames including the mobile service data and a signaling information table, a signaling encoder configured to encode signaling information including fast information channel (FIC) data, and transmission parameter channel (TPC) data, a group formatter configured to form data groups, wherein at least one of the data groups includes encoded mobile service data, known data sequences, the FIC data and the TPC data, and a transmission unit configured to transmit the broadcast signal including a parade of the data groups.
Abstract:
A digital television (DTV) signal for use in a DTV receiver includes an extended text table (ETT) which includes a header and a message body. The header includes a table identification extension field which serves to establish uniqueness of the ETT, and the message includes an extended text message (ETM). If the ETT is an event ETT, the table ID extension field includes an event identification which specifies an identification number of an event associated with the ETT. On the other hand, if the ETT is a channel ETT, the table identification extension field includes a source identification which specifies a programming source of a virtual channel associated with the ETT. A section-filtering unit included in the DTV receiver is able to use table identification extension fields of a plurality of ETTs for section-filtering a pertinent event or channel ETT from the ETTs.
