I queried the 'Freeviewshops ?tech-support?' if the UltraPlus boxes re-use the same up-scaling/de-interlacing circuitry for UltraPlus X9200HD and X920HD models, and they confirmed that they do as I would have expected.
He also said,
"ST chipsets perform best , Ali is also OK, Broadcom is good but suffers from combe effect due to lack of multi field motion adaptive deinterlacing".
Does anyone know about DishTV S7090? What chip is it using for Up-scaling/de-interlacing.
I am not totally convinced of the merits of ST chipset, as I have not heard of it or any of the others in my research.
Has anyone done benchmark testing to compare the up-scaling/de-interlacing from Std definition PAL upto Highdefinition1080p? This would probably be done from a USB plug in device and would follow the same de-interlace/scaling process as would the decoded Satellite feed.
