Component 720p through amp

[leedsfireman]

Hi, does any body know if my Yamaha AX630 amp with allow HD 720P to be passed through if it is used as a video switcher.
Thanks.

I play 720p WMV from my Showcenter 200 through my Yam 650 amp component input with no porblems at all.

Will depend on the quality of any switching, buffering and distribution amplification, and how high a bandwith signal they will pass.

Can you explain what you mean please.

HD component is an analogue interconnect standard. Analogue circuitry inherently has bandwith limitations. SD component is significantly lower bandwith than HD. (SD luminance has around a 6MHz bandwith, and chroma-difference around 3MHz. HD luminance is around the 30MHz bandwith, with chroma around 15MHz)

If the internal circuitry inside an AV amplifier - such as switching (this is usually performed by electronic, not physical, switches these days) and distribution amplification (the electronics that allow one input to feed more than one output) is designed with a lower-than-HD bandwith in mind, then it may well pass HD, but degrade it as it goes. The poorer the HF performance, the softer the resulting picture. (Even cabling has bandwith limitations)

The short answer is that not all component capable AV amps may be equal - you need to look at the bandwith they will happily pass.
