Maximum permissible delay between user action and feedback from Television

Hi,

I am working on television EPGs. I was wondering about the maximum permissible delay between a user action and the feedback from Television.

Eg: User presses ChannelUP button on the remote control. TV responds to the action by changing channel. What should be the maximum allowed delay between this for a good user experience?

Jakob Nielsen talks about 3 response times - http://www.nngroup.com/articles/response-times-3-important-limits/

I am not sure whether it is applicable for TV watching scenario too.
