So far, there is no way to pass Freeview signals through a digital interface (HDMI or DVI) Freeview signals will only pass through analogue outputs, as the signal, althoug in digital format when it arrives to your aerial, is converted to analogue via the decoder in the set top box or built in decoder in the TV) From worst to best, the connections you can use are : RF (aerial) passthrough, composite video (single yellow RCA ) s-video (4 pin din) Scart (CvBS - basically s-video quality) or RGB Scart (best)

However if you buy a Topfield TF5800PVR, you have the ability to output component (YUV/YPbPr) via the RGB scart socket, for which you only need an adapter cable (see HERE )

So, if you really want to limit your cable run, what you want to do is get a Topfield and output the YUV component via the scart socket, into this amp;

Sony STRDA-5200ES

THis amp has component and HDMI inputs, along with component and HDMI outputs. But whats special about it, is that it has the ability to upscale and pass through component signals via the HDMI output. So if you connect your Topfield freeview box to the component intput on the amp, you can pass this signal out though the HDMI output on the amp to the TV. THis means you dno't have a bunch of cables running from the amp to the TV, and also you can use the av amp to do the video switching aswell as the audio switching.

However, if you are installing cables in the wall, then you'd be wise to future proof yourself and install at least one cable from each type into the wall space, as you never know what you might need! Don't wanna have to keep ripping the wall conduit out to run another cable
