Fortunately, there are tons, of actual live stream channels covering the Asian Games. Unfortunately though, I have yet to find anything that covers basketball, billiards, and boxing. Furthermore, the choice of games being covered is at the mercy of those TV stations. So more often than not, you can never really be sure if your favorite events are being or will be covered.
Nonetheless, I am sharing with you these links, you may find it useful. Take note again that these are not my sites, bu rather from my scouring on the net.
