As part of my effort to build a replacement for the FrameChannel service I captured a sample of the existing RSS feed my frame receives.
Fundamentally it is an implementation of the Yahoo MRSS (Media RSS) specification. You can find details here and here.
If you are interested in grabbing a copy of your frame’s feed you’ll need the custom URL for your frame and to set the USER-AGENT header to ‘AVOS/1.1 libhttp/1.1’ (without the quote marks of course).
My frame requested this URL:
http://rss.framechannel.com/productId=KDxxxx/language=en/frameId=xx:xx:xx:xx:xx:xx
I’ve removed some of the details so as not to tempt the nefarous among us. The ‘frameId’ field is obviously the MAC address of my frame. I’ve not yet figured out how productId is derived.
