| IPTV isn't strategic for broadcast video
In the long term, IP Video doesn't really have a play to replace broadcast TV. Unicast feeds don't scale, as the amount of infrastructure required has a linear relationship to the number of viewers. If you have 10 million viewers, you need 10 million times the bandwidth of a single viewer and all of the supporting server hardware to facilitate that delivery. Of course, there is an IP based solution to this problem with multicast, but the multicast argument is simply one of using a bigger hammer to drive a square peg into a round hole. Once you implement a multicast solution, you're left with the same real-time streaming solution you have with existing QAM / QPSK / 8PSK / etc delivery options, only with the added bonus of IP overhead and more expensive intermediate delivery hardware.
When people talk about IPTV today they like to reference things like Hulu. If you look at the top viewed content it is programs that have been aired on network TV, which is ridiculous from an efficiency standpoint. So you take a program that has already been digitally delivered to your house over the air in a 19.2mbps MPEG2 ATSC feed by public broadcast TV stations, probably over a cable line into your house on clear QAM, and from at least a half dozen different satellites that you could pick up with the appropriate hardware. Rather than investing in a more clever / cost effective way to capture one of those existing delivered feeds, we're focusing on network-based delivery? This is pure absurdity.
When it comes to one-off content like a massive library of movies (ala NetFlix), smaller audience material (ala Youtube), and backfilling lost/missing content the IP distribution model makes sense. For primary delivery of mass media content, we already have highly cost effective delivery solutions in place today. | |

What cable has to do and be allowed to do legally is what TWC tried - Storing of broadcast shows on servers(remote DVR) that can be accessed locally thru OnDemand connections.
Either that or have STBs with TerraByte drives that can record and store more shows for longer periods of time.
Either of the above lets the more efficient broadcast model thrive while adjusting to viewers need to time shift TV watching.

This is pure absurdity. it shows that existing delivery systems are not fulfilling the needs of consumers. a true "on demand" and a la carte system is what consumers want, and yes, there are several other delivery methods but the only delivery method that fits the desire of consumers is IPTV.
this is an area that cableco could really shine, but hasn't. they have an on-demand service, but they need to get aggressive to stall the IPTV and internet delivery options. hell, if cableco would DEVELOP their on-demand systems and partner with networks there would be no need for all these spinning harddrives of Tivos and DVRs in consumers' homes. | |
