ZHCSNH1C May 2021 – November 2022 DLPC6540
PRODUCTION DATA
The DLPC6540 introduces a variable number of field/frame delays dependent on the source type and selected processing steps performed on the source. For optimum audio/video synchronization, this delay must be matched in the audio path. The following tables define the various video delay scenarios to aid in audio matching.
Because the input and output rates are different when frame rate conversion (FRC) is employed, the delay through the FRC is variable.
FRC TYPE(3)(4) | SOURCE EXAMPLE | DE-INTERLACING | FRAME RATE CONVERSION (INCLUDES WARPING) |
FORMATTER BUFFER | TOTAL DELAY |
---|---|---|---|---|---|
ASYNC (↑) | 10-47 Hz Progressive Graphics | Disabled (0 Frame) |
1 to (1 + N) Frames | N Frames | (1 + N) to (1 + 2N) Frames |
SYNC (1:1) | 47-120 Hz Progressive Graphics | Disabled (0 Frame) |
1 Frame | 1 Frame | 2 Frames |
ASYNC (↓) | 63-120 Hz Progressive Graphics | Disabled (0 Frame) |
0 to N Frames | N Frames | N to 2N Frames |
SYNC (↑) | 24-30 Hz Progressive Video | Enabled (5) (1 Frame) |
1 Frame | N Frame | 2 + N Frames |
SYNC (1:1) | 60 Hz Progressive Video | Enabled (5) (1 Frame) |
1 Frame | 1 Frame | 3 Frames |
FRC TYPE | SOURCE EXAMPLE | DE-INTERLACING | FRAME RATE CONVERSION (INCLUDES WARPING) |
