DATA TUNNELING VIA CLOSED CAPTIONING |
摘要 |
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. |
