Convert from a EIA_608 stream to a SMPTE_436M_ANC data stream, wrapping the closed captions in CTA-708 CDP VANC packets.

line_number

Choose which line number the generated VANC packets should go on. You generally want either line 9 (the default) or 11.

wrapping_type

Choose the SMPTE 436M wrapping type, defaults to vanc_frame. It accepts the values:

vanc_frame

VANC frame (interlaced or segmented progressive frame)

vanc_field_1, vanc_field_2, vanc_progressive_frame

sample_coding

Choose the SMPTE 436M sample coding, defaults to 8bit_luma. It accepts the values:

8bit_luma

8-bit component luma samples

8bit_color_diff

8-bit component color difference samples

8bit_luma_and_color_diff

8-bit component luma and color difference samples

10bit_luma

10-bit component luma samples

10bit_color_diff

10-bit component color difference samples

10bit_luma_and_color_diff

10-bit component luma and color difference samples

8bit_luma_parity_error

8-bit component luma samples with parity error

8bit_color_diff_parity_error

8-bit component color difference samples with parity error

8bit_luma_and_color_diff_parity_error

8-bit component luma and color difference samples with parity error

initial_cdp_sequence_cntr

The initial value of the CDP’s 16-bit unsigned integer cdp_hdr_sequence_cntr and cdp_ftr_sequence_cntr fields. Defaults to 0.

cdp_frame_rate

Set the CDP’s cdp_frame_rate field. This doesn’t actually change the timing of the data stream, it just changes the values inserted in that field in the generated CDP packets. Defaults to 30000/1001.
