The SES-Astra Sat>IP specification uses real time streaming protocols to deliver selected services to various Sat->IP clients in the home. The approach has some disadvantages though: every Sat>IP client is in fact a dedicated Sat receiver, including dedicated CA and middleware functions if required for the service. The DLNA approach require a heftier gateway (including possibly transcoding) but offers much bigger client flexibility, including a centralized CA model.
The trend in clients is written on the walls: dedicated 2nd screen clients are on their way out fast. Maybe SES-Astra should reconsider their IP strategy or address the disadvantages of the present Sat>IP concept quickly. The videonet article below addresses the tradeoff between the two approaches as perceived through somewhat colored (Sat>IP) glasses.
