Mode 6
Mode 6 should be used if:
•
Two separate upscaled resolutions are required
•
De-interlacing is not required
•
OSD is required on one resolution only (preferably the lower upscaled resolution output)
Figure 16:
Mode 6 Configuration
Mode 6 places the OSD blend block after the SVSP. Both the PVSP block and SVSP work in parallel in this mode. As the OSD is only on one
data path, it will only be displayed at a single resolution. As shown in the example in
, the input to the SVSP must be a progressive
format. Therefore, this mode can only be used when the input is progressive.
It can be seen from
that the same output formats can be generated in this mode. However, due to the change in location of the OSD
blend block, the OSD can only be generated on a single output resolution.
Note:
De-interlaced inputs can be input to the device in this mode. However, the SVSP can only accept progressive input formats. Therefore,
the SVSP would be excluded from the processing in this case as would the OSD blend.
