    LEI-599 - Overview

    The LEI-599 will accept HD SD SDI transport streams with embedded closed captions and other ancillary data and decode and re-insert those captions in the outgoing HD/SD-SDI stream so that the captions now appear during active video. Captions which appear in active video are called "Open" captions. CEA-608-B based streams will decode CC1, CC2, CC3, CC4 and text service T1. Text service T2, which is used by MSN-TV to transmit the internet links for their service, will not be decoded.

    Channel CC3 is now used to transmit the eXtended Data Service (XDS) packets which is decoded to the front panel LCD display.

    The LEI-599 will also display open captions for CEA-708-B based (DTVCC) service 1 and service 2 data streams. Finally, the eight variants of the Active Format Description (AFD) codes as described in SMTPE 344M and SMPTE 2016-1 will be detected and displayed on the LCD.

    Once the closed captions are decoded, they are active in the HD SD SDI output video signal as displayed on the video monitor.

    Every effort is made to keep the latency between the open and closed captions to a minimum. The XDS and AFD decodes can be viewed on the front panel 40 character (2-line) LCD display. A front panel navigation switch is used to scroll through and select which of the XDS data fields are to be displayed. The navigation switch will also access the LEI-599 setup menus.
