I'm an interworking engineer. I know networking (routing, switching, transport, etc) very well, an that includes technologies that allow the transporting of various media (native data, voice, video, signalling, etc) over various layers (i.e 1, 2, 3, etc)
Years ago I deployed a 'VoIP' system, but it was not VoIP, no where near it. The system encoded voice (audio and signaling) into ATM cells, sent that over ADSL, and the far end device stripped off the Layer 2 and terminated the voice onto an analog port. IP traffic was also done the same way so there was an Ethernet/IP port to connect your PC too. So the marketing hype on this system said the voice was carried VoIP, but it was not.
When I read about Aliant IPTV, I noticed that there is this key requirement of having the DSL being within a certain specification, and from what I know of Telco thinking, I get the funny feeling that while they call it IPTV, the actual TV is encoded into Layer 2, not Layer 3 (IP). I also noticed that (according to Aliant) there is the requirement for an Ethernet switch (a layer 2 device) between the DSL modem, and the set top box. There is also the note that users must have the new Aliant High Speed PPPoE service. (PPPoE is Layer 2, not Layer 3.) Give what I know about old school Telcos, and their old circuit-switched mentality, I think (but honestly don't know for sure) they send the IPTV over a seperate PPPoE vircuit-circuit (account), and not over IP. (Technically IP could still be used, but they have still locked (siloed) into that seperate PPPoE VC.) If they did do it over IP (ubiquliously), why couldn't you simply install a high-quality (IP) router to terminate the one PPPoE account, and then use IP routing. And if they did it over IP, why would they not want to make it available via the Internet (the largest IP internetwork there is!) and open up their market to include not just Aliant net customers, but anyone else who wants to give them money.
Their on-net customers may be required to upgrade their DSL to provide more bandwidth, but this is Layer 1, and should have nothing to do with Layers 2 and 3.
So, can you confirm that Aliant encodes its TV streams (audio and video) over IP (Layer 3), and not directly into some Layer 2 protocol?
Actually it doesn't matter. If Aliant won't sell me IPTV with me being an Eastlink customer at a higher-value service than what Eastlink offers then I won't buy.
So if anyone knows of an IPTV provider (I don't even care if they are in Canada) that makes their service available over the Internet, please let me know. My telephony service provider in not in Nova Scotia, so why should my TV service provider be?
