According to Broadcast, the new approach will see the satellite broadcaster introduce a 'HD Swap Bouquet' alongside its 'Standard Bouquet' of channels.
The system, due to go live on February 1 next year, will mean that HD channels can swap positions with their SD counterparts to move further up the EPG.
Sky hopes that the approach will ensure that Sky+ HD subscribers always make use of HD channels where they are available, rather than just watching SD versions.
For example, the HD Swap Bouquet will mean that Sky1 HD will shift from position 170 on the EPG to 106, where the SD channel currently sits.
Sky customers will get access to the HD Swap Bouquet if they subscribe to at least one HD channel. Broadcasters will be able to opt out of the system before it comes into force, but they will have to contact Sky first.
