Can I use BBC Four HD iPlayer stream in Channels?

Hi, just to be clear I have no interest in using illegal streams or circumventing region restrictions. I live in the UK and my area's transmitter doesn't transmit BBC Four in HD, I wondered if anyone had found a way to get the freely available (with a valid TV Licence and BBC Account) HD stream from the iPlayer into Channels either via an m3u file or similar? I previously had this working with an HLS link I found online but I don't think it was a BBC provided link and it has since gone down. So I know in principle that it works with Channels but I wondered if there was a more legitimate or reliable method to get a legal stream into Channels. Thanks!
