    • An example apparatus that processes DTVCC data has a demultiplexer that extracts DTVCC data packets from an DTV signal. A parser receives the DTVCC data packets and parses the data packets by: passing normal DTVCC data to a CC decoder; detecting ancillary data in the DTVCC data packets; and separating the ancillary data from the DTVCC data for output to an ancillary data process. An example apparatus that processes DTVCC data has an ancillary data packager that packages data ancillary to DTV data for insertion into the DTVCC data packets. A DTVCC data packager receives CC data from a CC data source into DTVCC data packets and packages the ancillary data together with the DTVCC data into DTVCC data packets. A multiplexer multiplexes the DTVCC data packets from the DTVCC data packager with non-CCDTV data to produce DTV signal data. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
    • 处理DTVCC数据的示例性装置具有从DTV信号提取DTVCC数据分组的解复用器。 解析器通过以下方式接收DTVCC数据包并解析数据包:将正常DTVCC数据传送到CC解码器; 检测DTVCC数据包中的辅助数据; 并将辅助数据与DTVCC数据分离以用于输出到辅助数据处理。 处理DTVCC数据的示例性设备具有辅助数据包装器,其将数据附属于数字电视数据的数据打包到DTVCC数据包中。 DTVCC数据包装器从CC数据源接收CC数据到DTVCC数据包,并将辅助数据与DTVCC数据一起打包到DTVCC数据包中。 多路复用器将来自DTVCC数据包装器的DTVCC数据分组与非CCDTV数据复用以产生DTV信号数据。 该摘要不被认为是限制性的,因为其它实施例可能偏离本摘要中描述的特征。

    • A method of controlling a system for providing access to teletext information, comprising, an input for receiving a source signal, a channel selection system for selecting a program channel signal carried by the source signal and including embedded teletext data belonging to a teletext service, a teletext decoder for decoding teletext data embedded in a selected program channel signal, a coder for converting decoded teletext data into a video signal for displaying teletext information on a display device, memory for storing pre-set data including information identifying at least one pre-set program channel signal, an interface for receiving a switch command entered by a user, comprises receiving a switch command through the interface. The method further comprises, in response to the switch command, searching at least a part of decoded teletext data embedded in the pre-set program channel signal for identification information identifying a teletext information provider and directing the system to convert at least part of the decoded teletext data into a video signal if identification information is found corresponding to pre-set identification information included in the pre-set data.
