I would like to add iptv to my wireless service and am looking for information on the subject. Can anyone direct me to the very basics of getting into this technology? What do I need to know or do to get started?
Thanks in advance! |

| Without getting into the nitty gritty of technical hurdles, what exactly are you invisioning?
Keep in mind, Canadian laws allow for things US laws do not.

| Basic question, how much bandwidth are you feeding your users?
a SD feed of IPTV, will be around 2mbps, where as a HD feed will be around 9mbps. That is PER Set top box/channel.
Meaning if you have a user with 3 TV, all watching different SD feeds, that is 6mbps, just for IPTV.

A basic IPTV system without video-on-demand (VOD) is feasible if you have the budget to deploy high throughput pure LOS 5Ghz (or licensed) backbone and matching routers that are IGMP and QoS capable.
IPTV terminals are quite inexpensive and sleek this days. Amino is a better brand. Choose MPEG4 capable units with one or two Ethernet ports. »www.aminocom.com/products/ipstb/index.html
*** but now the gotchas ***
#1 gotcha is the actual TV channels
You could select favorite TV channels from the multitude of satellites available and encode for IPTV (legally of course) »www.lyngsat.com/america.html
Or negotiate with companies like Cancom that do this job already for cable companies. »www.cancom.ca/
#2 gotcha is wireless throughput limitation
Current 802.11b/g WISP gear is not suitable for serious IPTV distribution. You have to wait for 802.11n with 802.11e multimedia support.
It maybe possible to use 5Ghz high throughput CPE to feed a whole building and use CAT5 wiring within the building to feed apartments. But still your IPTV service will have limited number of channels.
You could compensate by providing VOD and other services, but they require massive servers. |

as far as bandwidth goes, my ISP has given me 130G for my business. My data rate is at 18mbs for 802.11g and 11mbs for 802.11b. So if I understand correctly, the data rate is at 18mbs and 1 set top box needs 9mbs for HD, then I would only be able to provide for 2 tvs? |

| The data rate does not mean the actual bandwidth you get. You should generally divide the data rate in half and that is the actual bandwidth you get.
Also, the 9mbps you will get for bandwidth is per access point, not per client. So, all the clients connected to that AP will have 9mbps to share, not 9mbps each. IPTV will NOT work with wireless as of yet. We need to get a higher bandwidth wireless standard such as 802.11n first.

Re: iptv
As a logical expansion of this topic, what sort of devices would be required at the "headend"?
Hypothetically, lets say I wanted to redistribute Channel 8, City Govt, from my local CATV service to my subs. Distribution medium excepted, as obviouslly wireless wont work, what devices would be required to "create" the "iptv" at the noc?

You would need a source of TV Programming. You can't just pay $50 for cable and redistribute it into your IPTV network. You need to pay BIG BIG bucks to have the right to distribute the programming.
Next, you need the equipment to receive this tv programming. Then you need IPTV encoders to encode the programming into ip based packets. Then you need lots switches and a core router and crap. You then need to get it out to your customers with either ADSL2+, VDSL, or FTTP.
In the home, you need an IPTV decoder such as the Amino that is listed. That will decode the IPTV stream from the IPTV encoder and your television pops up.
This is just a very simple explanation and goes into NO detail. This would be very complicated and so far, only VERY FEW companies in the U.S. have started offering IPTV. Some are AT&T Uverse, Cavalier Telephone, and our local phone company, KMTel.
This is not something a small business can implement. This takes lots of work. KMTel will be deploying the IPTV service in our area in 2 weeks after all the beta testing is done. They decided to use Paradyne ADSL2+ equipment in our area. We get telephone, television, and 1meg DSL for $91.95 plus taxes.

| said by aSic  :As a logical expansion of this topic, what sort of devices would be required at the "headend"? If you are not doing video-on-demand, you only need a few multi-LNB dishes on a rooftop, a bank of DVB receiver + MPEG4 encoder cards on a rackmount chassis, and IGMP capable router.
Number of dishes, receivers and encoders only depend on how many channels you want to broadcast and which satellites happen to carry them.
In North America IPTV is the domain of the big companies, but there are many small IPTV operations in Asia. Since they do not need NBC/ABC/CBS/Fox, their licensing costs are a small fraction of their revenue.
In North America, a few distribution companies like Cancom have reasonable cost packages aimed at apartments and hotels.
Almost all "free-to-air" TV stations I contacted seem delighted that you will encode their independent programming "for free" since the big networks rarely give them national exposure.
There are also large number of "free-to-air" satellite TV channels, but most of them are from overseas countries. I also hear that some overseas IPTV companies simply forget to notify CNN or Al-Jazeera that they are re-broadcasting their channels. |

If all you wanted to do was a single channel it would be easiest to get an MPEG-4 encoder that supports RTSP multicast. From there anyone with Quicktime can view the stream and you can include a link to the broadcast on your company homepage.
In order to do this legally you would need permission from both the cable co and broadcaster (in this case the city government).
