I believe what they are saying is that the image is internally processed by the camera at 1920x1080. But when you record to tape, it will be squeezed to 1440x1080. The playback device then understands to stretch the image back to 1920x1080.
Something similar is done on the XL2 in widescreen mode. The CCD's use a 960x480 array, but 720x480 is written to tape, which is anamorphic 16:9 standard definition.
Look at the page about the CMOS sensor on that same site: http://bssc.sel.sony.com/Broadcastan...U/devices.html Here you will see that the sensors have 960x1080 effective pixels. The EIP chip interpolates the data from the chips to create a 1920x1080 progressive image. Then it's scaled down to a 1440x1080 4:2:2 interlaced image which is available through the analog component video jacks. Finally it undergoes the HDV compression process before being written to tape.
