Frame Status Conversion
5-215
5Frame Status Conversion
Purpose Specify the frame status of the output, sample-based or frame-based.
Library Signal Management / Signal Attributes
Description The Frame Status Conversion block passes the input through to the output,
and sets the output frame status to the
Output signal parameter, which can
be either
Frame-based or Sample-based. The output frame status can also be
inherited from the signal at the
Ref (reference) input port, which is made
visible by selecting the
Inherit output frame status from Ref input port
check box.
If the
Output signal parameter setting or the inherited signal’s frame status
differs from the input frame status, the block changes the input frame status
accordingly, but does not otherwise alter the signal. In particular, the block
does not rebuffer or resize 2-D inputs. Because 1-D vectors cannot be
frame-based, if the input is a length-M 1-D vector, and the
Output signal
parameter is set to
Frame-based, the output is a frame-based M-by-1 matrix
(i.e., a single channel).
If the
Output signal parameter or the inherited signal’s frame status matches
the input frame status, the block passes the input through to the output
unaltered.
Dialog Box
Inherit output frame status from Ref input port
When selected, enables the Ref input port from which the block inherits the
output frame status. Tunable.
Output signal
The output frame status,
Frame-based or Sample-based. Tunable.
