4.2.3.2 VoSPI Segments
Each valid Lepton 3 segment contains data for one quarter of a complete frame. With telemetry disabled, each
segment includes 60 packets comprising 30 video rows. When telemetry is enabled, each segment includes 61 packets
comprising 30.5 rows. Note that with telemetry enabled, two rows (4 packets) of pixel data is replaced by the telemetry
lines; pixel data is either shifted down in which the bottom two rows are excluded (header mode) or up in which the top
two rows are excluded (footer mode). With telemetry enabled as a header, packets 0 -3 of segment 1 provide the
telemetry data and the remaining 57 packets of segment 1 provide data for the first 28.5 rows of pixel data. Segments
2, 3, and 4 each provide data for 30.5 rows of pixel data. When telemetry is enabled as a footer, segments 1, 2, and 3
each provide data for 3.05 rows of pixel data whereas packets 0 – 56 of segment 4 contain 28.5 rows of pixel data, and
packets 57 – 60 provide the telemetry data. The location of the telemetry lines is illustrated in Figure 36.
