  • Publication number: 20070252755
    Abstract: A digital broadcasting receiver with DGPS RTCM data output port and a terminal for supporting the DGPS service using the same are disclosed. The digital broadcasting receiver having DGPS RTCM data output port, includes: a radio frequency processing unit for receiving digital broadcasting signals and converting the received signals into baseband data; a decoding unit for decoding the baseband data to generate decoded data; a DGPS information extractor unit for extracting a Differential Global Positioning System (DGPS) information from a DGPS data which is one of the decoded data; and a RTCM104 formatting unit for converting the DGPS information into RTCM104 data which is compatible with the DGPS RTCM data input port and outputting the RTCM104 data through the DGPS RTCM data output port.

  • Publication number: 20060056524
    Abstract: An apparatus for transmitting data in a digital broadcasting system is disclosed. The apparatus includes: a source encoding unit for encoding data to be transmitted and generating source-coded data; a capacity managing unit for dividing the source-coded data into divided data for a plurality of channels in case that an available data capacity for transmitting the source-coded data does not exist in one channel but sum of available data capacities of the multiple channels can accommodate the source-coded data, and adding header information to the divided data; a channel encoding unit for encoding the divided data according to channel environment and generating channel-coded data; and a transmitting unit for multiplexing, modulating and transmitting the channel-coded data through multiple frequency bands and multiple broadcasting sites.
