Mode 1
Mode 1 should be used if:
•
Three separate output formats are required
•
Additional processing (BNR, RNR, and so on) is required on the new output formats
•
OSD is required on a single output format (most likely the lowest quality of the converted formats)

Mode 1 Configuration
Mode 1 places the PVSP after the input block. The output from this block is then sent to the SVSP or the PtoI converter. The OSD blend block
can then be placed after the SVSP block.
In the example in
, the input resolution is taken to be 480i. This is then passed through the PVSP where it is converted to 1080p using
motion adaptive de-interlacing. This can then be passed straight to the output, to the PtoI converter or, alternatively, to the SVSP and OSD
blend. The example output formats generated using this mode are 720p (with OSD), 1080p and 1080i. The input SD format of 480i can also be
passed to the SD encoder.
