DVB-C v DVB-T

Solair

Just purely our of curiosity I was wondering how come Chorus and NTL / UPC Ireland are using a mixture of DVB-T and DVB-C?

Which networks used it and why ?
E.g. do we have any cable networks in Ireland using DVB-T ?


If so, does this limit the number of channels they can carry ?
Or have any other impacts?

Easy explanation, cable is used throughout the citys and certain towns therefore DVB-C was used, DVB-T was used as a cheaper alternative to providing potential customers around the countryside with a method of receiving transmitted channels by wirelessly transmitting the signal to their homes.

However around the country there was a number of different cabling companies before these were swalloed up by Chorus and NTL etc, and each used there own equipment and frequencies.

For example in the Limerick clare area, analog equipment used is manufactured by companies such as Jerrold And General Instrument but in Cashel and clonmel analog equipment was manufactured by Pace. All digital equipment is the same manufactured by sagem but the equipment used in Limerick for MMDS is used on the cabling system in Clonmel...

Yeah its a strange setup in Clonmel, never seen a cable system that runs off terrestrial equipment.

Yeah it certainly is a strange setup there alright especially when u work for them as they don't even tell you anything bout the networks so when I arrived up there to do installs at first I hadn't a clue what equipment to use...so I never knew what to order each week....thankfully those days are over..

Steveon are they planning on upgrading Clonmel at any stage in the future to the rest of the network standard of DVB-C at any stage or would it cost UPC to much to do?

I dont know to be honest, as I'm no longer working there, but one thing I can tell you is that I would expect them to, because when Sierra arrived in Limerick to upgrade the cabling systems in Limerick which is currently onway they were also given maps of Thurles and Cashel and Clonmel...what this means is anyones guess but I would expect that in time all networks would have to be upgraded as they simply cannot offer a superior package to different customers around the country and retain the same charge for every customer as has been for far too long.

Too many people in my opinion still dont know about Digital MMDS and are still using Analog MMDS and paying almost the same cost...I guess in all only time will tell, but I would expect Clonmel to maybe end up under the NTL lineup rather than stay in chorus..

Snake Plisken

Yeah from a releation of mine the actual cabling going into the house looks pretty poor quailty looks like the Town needs a full upgrade, although saying that the Analog channels look a lot better then then the Ntl analog I have here in Lucan.

You can say that again, every job I ever done up that way, had either damaged or ill efficient cabling used previously so I had a lot of rewiring to do..and even driving around a lot of cables are hanging loose so definetly deserves let alone needs a lot work..:eek:

How are they providing cable internet ? I didn't know this would work over MMDS ! ?

No what we are on about here is that in Clonmel chorus supplies the cable tv, but rather then use DVB-C equipment for their digital package they are using DVB-T decoders which are normally used on MMDS systems. so modem is just connected to the normal cable system

So their using DVB-T equipment on Fixed cable .... Thats bizarre :eek:

Thats like South Coast TV using DVB-S and a satellite dish pointed at the ground for terrestrial transmission
