Service 1 Only
ITU-608 pass-through for 480i59.94 Input/Output processing (all incoming services will pass through,
i.e. CC1, CC2, CC3, CC4, T1, T2, T3,T4, and XDS).
ITU-608 to ITU-708 translation for 480i59.94 up-conversions to 720p59.94 & 1080i59.94 (only the
primary language from CC1 will be transcoded to DTVCC service S1).
ITU-708 pass-through for HD Input/Output processing for 720p59.94 & 1080i59.94 (all DTVCC services
will pass through, the frame rate and checksums will be adjusted as necessary).
ITU-708, Line 21 extraction for down-conversions from 1080i59.94 or 720p59.94 to 480i59.94 (only if the
line 21 data is present in the 708 CDP, otherwise the output will contain a clock-run-in with null text).
