Single Interface Mode 2 (D1)
Accommodates 2 synchronous multiplexed D1 streams
for low cost applications (both streams are extracted).

Interleaved interface mode
Same formats as in single interface mode 1 and 2 but
only one of the two interleaved video streams is
extracted per interface.
Selection of the extracted slice is possible by software,

Table 9: Combined double D1 mode
Display/interface mode
Mode
Combined double D1 mode:[1] the two D1 interfaces are 2 combined D1
combined to carry a single HDTV stream in 4:2:2 YUV or 8/10-bit
4:2:2 YPrPb format
primary D1: Y channel
secondary D1: muxed UV or PrPb channel
i.e.: 1920x1080 60 Hz interlaced
2200 pixel/line x 562.5 lines/field x 60 Hz = 74.25 MHz/Y

[1] In case of the combined double D1 mode, no secondary display channel is available
The PNX8510/11 supports color space conversion only in the primary RGB standard
definition data path. For the high definition part of the primary video data path and for
the secondary video data path no color space conversion is available. Hence the
video data has to be provided in the display destination color space.
Aside from built-in video encoders, which generate all necessary timing and filtering
for an appropriate sync raster for PAL, NTSC and SECAM, the PNX8510/11 contains
a separate raster-generation engine which also supports but is not limited to the
HD-formats, such as the SMPTE 274M. The PNX8510/11 also contains an
up-sampling filter to convert 4:2:2 formats (other than standard definition formats) to
4:4:4.
In the case of combined double D1 mode, no secondary display channel is available.
