For pinyin, there are some browser extensions for Chinese dictionaries, where you can hover over a word and get the pinyin (or bopomofo ;)).
I'd like to implement these eventually, but for now I think it's best to mix and match different tools to fit your own needs.
Live TV and audio transcriptions shouldn't be too difficult to implement, any particular sources you'd like to see?
