What the heck? Do you have any clue what the motivation is behind this?
- chomp 13y agoYeah like tacoman said, it's for channel changing. Multicast saves on bandwidth.
- tacoman 13y agoIt's how they deliver instant channel change. The unicast udp burst is about 30% higher than the nominal bitrate of the multicast. The STB stitches the unicast and multicast together seamlessly.
- hahainternet 13y agoThat is an impressively smart solution really. I don't have instant channel change :(
