2-Layer Keying with the TMC22091
The TMC22091 facilitates the keying of PD port input data
over the CVBS bus input data. Keying is controlled on a
pixel-by-pixel basis by either the KEY input pin or the inter-
nal Data Key. The first two layers in the previous 4-Layer
Example apply to the TMC22091. The result of keying is an
effect where a MIDGROUND source image (i.e. Happy Face
from PD data) is superimposed over a BACKGROUND
source image (i.e. variable matte color from CVBS data).
Assigning Video Sources to Layers with the
TMC22191
Digital video inputs to the TMC22191 (PD, CVBS, Overlay)
are assigned to the four layers by choosing one of the 16
modes of the Layering Control Register. OVERLAY is
always keyed (switched on a pixel-by-pixel basis from active
to transparent) by the OL
4-0
inputs. OVERLAY can not be
programmed to the BACKGROUND layer. The CVBS digi-
tal video bus can be assigned to any of the four layers and is
keyed by the KEY input signal or internal Data Key. In
modes 0 thru 7, the CLUTs are not bypassed and the
BYPASS input is ignored.
Table 14. Layer Assignments, Image Sources, and Keying Controls (TMC22191)
Notes:
1. For LAYMODE = 0 to 7, Pixel Data always passes through the CLUTs. FORMAT, INMODE, and the BYPASS pin selects the
input format for PD
23-0
according to Table 6.
2. For LAYMODE = 8 to F and BYPASS = HIGH, Data Key is disabled.
3. Asserting the signal listed under "Keying Control:" enables the corresponding "Signal Source:". Signals with " " are asserted
by a logic LOW.
