    This 3d tv seems to be popular now ,I think some stores are selling it for around a grand.

    http://www.amazon.co.uk/Samsung-LE40C750-Widescreen-Allshare-Internet/dp/tech-data/B003JEVQRK/ref=de_a_smtd
    It has freeview HD too so that means it will work with Irish Mpeg4 right?


  • Closed Accounts Posts: 5,178 ✭✭✭STB


    Unless you can receive Freeview HD they are useless though. Same goes with 3D. This whole 3D thing em.....

    Look you can get a DVB-T MPEG4 LCD or Plasma for less than half that price.

    3D isn't popular. Don't mistake expensive glossy marketing and news reports for Popularity! Before seeing it 25% are interested. After demonstrations only 12.5% are still interested. It's a way to sell new more expensive TVs. 3D films where 8% of cinema attendance. Most of those would have still been watched if not 3D. If a film isn't good in 2D it's only novelty value.

    3D is actually the Victorian Stereoscopic system and identical to Viewmaster toy. It doesn't even work for 1/5th of population and gives almost everyone a headache with prolonged viewing.

    It's not 3D Production companies are renting rather than buying "3D" equipment and no broadcaster has committed to in house "3D".

    It may be good for certain games and new Nintendo 3DS handheld.

    For people that are choosing 3D that samsung tv is a popular choice ,thats what I meant.
    3D itself is not popular yet.
    The ps3 is being updated to be a 3D player next week, which will mean there will be 38 million 3d players worldwide next week and the sony have lots of upcoming titles in 3D,

    I think 3D just might become popular a lot of people who have played the console games in 3D say its amazing!
    You mentioned percentages about people not liking it etc. Im not fond of surveys at all , usually we know nothing about them. :mad:

    Are you saying that they wont recieve the Irish mpeg4 unless you can recieve the UK freeview hd channels in your area?

    No. Freeview HD can only be received in the UK or through overspill (ie coastal parts of Wicklow/Wexford or along the border with NIreland).

    It should work with DTT here but its not the same spec. Wait til confirmed as working. If you are not in the afore mentioned areas why buy one anyway when dvb-t mpeg4 tv's are half that price !

    Yes I learned on this forum that freeview only works in some areas, It doesnt work in my area in Donegal.
    3d would be my only reason for getting a freeview hd tv.
    So just to clarify here and avoid confusion, even though I cant get freeview hd in my area, If I got a freeview hd tv , it may still pick up the Irish mpeg4 channels?


  • Registered Users, Registered Users 2 Posts: 32,461 ✭✭✭✭watty


    A Saorview certified TV would be better.

    Also an HDTV (even 3D) with Freeview, rather than Freeview HD won't work. Avoid the extra (significant) cost of so called 3D.
    A "Freeview HD" HDTV may be OK. Wait till Nov/Jan unless you have no TV.


  • Registered Users, Registered Users 2 Posts: 5,294 ✭✭✭Deedsie


    I was just checking a friends tv. This tv isn't compatible with saorview right? Philips 32pfl7332/10

    I found this spec page but I am not sure what I am looking at:

    No it isnt (sound and no picture!). There is nothing in that spec sheet to tell you what its is! Sorry i meant to say its MPEG2 - they are common models sold in Ireland since 2007 and no good for DTT.

    You would normally see MPEG4 H264 or in the case of the latest Phillips LCD's, they actually include a a better spec sheet : Digital TV: DVB Terrestrial*, DVB-T MPEG4*, DVB-C MPEG4*.

    The ones with "H" at the end are the Phillips ones that do MPEG4. ie 32PFL9903H/10.

    Although many here are not keen on the "fake" 3D, it is still the same concept and im sure it looks pretty cool, even though its not 100% 3D I would still like to have a 3D tv.


  • Closed Accounts Posts: 5,178 ✭✭✭STB


    The Freeview HD TV should work, but I couldnt guarantee it. You should be able to get Freeview now though. Freeview HD isnt likely to come on stream until 2012, but you should receive the Freeview ones.

    I suggest you start a thread about Freeview availability in Donegal. The likes of "lawhec" is up that way and may be able to advise you.


  • Registered Users, Registered Users 2 Posts: 32,461 ✭✭✭✭watty


    What will you watch? It needs suitable Stereoscopic content.

    Check in a Harvey Norman's demo that you are not one of the 20% it doesn't work for. Also it uses special glasses, so if you wear glasses you have a problem. ALL viewers have to wear the glasses, even people that it doesn't work for as otherwise they see a double image. Or else you have to turn off the effect.

    Due to the hills and mountains only limited locations get N.I. freeview. A dish + Freesat is a more certain solution and has HD today.

    Thanks no I dont get freeview here ,I have play tv for the PS3 and its capable of getting mpeg4 and freeview but it cant find freeview, I think the hills is blocking the signal. One tv in the house (with bunny ears ) does pick up a very bad bbc, years ago we got bbc utv and ch4 no problem but not anymore.

    How come it doesnt work on some people?:confused:
    3D for gaming would interest me. But i might just settle for a HD TV until 3D proves itself in the market.

    Has anyone noticed that there is a delay of like 3 seconds with the mpeg4 broadcast compared to the original analogue.
    i.e. Irish mpeg 4 is 3 seconds behind analogue.
    I noticed this when someone in the next room is watching analogue , and I am watching mpeg4 ,there is a noticeable delay.

    It doesn't work on me. In order for 3D to work properly you need to be able to focus on both images at the same time to allow your brain to merge them together. However I can't focus using both eyes at the same time (amblyopia). I went to see Toy Story 3 in 3D and it just looked like a darker 2D film to me.

    I reckon up to 2 out of 3 people have problems with 3D and will at the very least get headaches from it on sustained viewing. I would not recommend anyone buy a 3D TV unless the entire household can view and enjoy a 3D movie for the entire 1 hour 30 minute runtime in the cinema.

    That's normal, it's the same for DAB digital radio versus analogue radio. It can be annoying if the TVs are within earshot of each other.

    The delay is due to the extra processing required for a digital transmission, encoding of the tv signal before transmission, and the decoding at the home. There can also be a delay between different digital TVs.

    See this post over in Digitalspy - Why is Freeview 4 seconds behind analogue

    I am looking for a new TV with MPEG-4 which many are out there but I also want to have a USB port that allow me to playback MPEG-2 TS format.
    Does anyone know of a TV that can do this MPEG-2 TS playback via USB?

    I have the Samsung LE40C530 and it can play MPEG-2 TS files, I used one recorded from BBC HD and it played back fine.

    MPEG TS is a format recorded by sat boxes. TS being the raw transport streams.


  • Registered Users, Registered Users 2 Posts: 32,461 ✭✭✭✭watty


    MPEG-TS = Transport stream. Format of all DVB transmissions
    MPEG-PS = Programe Stream. Package for all Video discs such as VCD, S-VCD, DVD, BD etc.

    Thanks, I know it is from my Humax box and for the file size is lot smaller,
    1 hour recording is just 1GB compare to same recording in MPG is 2.5GB while in another format of the same. M2TS is just 1.9GB

    what is M2TS?

    TS format allow bitrate is 15 Mbps
    MPG format bitrate is 6Mbps but 2.5 times bigger file size

    How is this possible, different compression or something else?

    They are only containers. M2ts is normally associated with AVCHD (MPEG4) files.

    The header on a saved TS may quote peak bit rate, or the original total stream before de-muxing the channel you want. or be fictitious. TS is live transmisssion and bitrate can't be known by receiver in advance and maybe vary.

    File size is related to average bitrate. With simple on the fly compression, often constant bit rate is used.

    Note that Variable bit rate peaking at 6Mbps and as low as 0.5MBps can be an average of 1.5Mbps. Using constant bit rate encoding would need 6Mbps for similar quality. Sudden movement, fast panning etc can easily overwhelm CBR set at too low a rate.
    VBR is of most advantage on a disc or statistically multiplexed selection of channels.

    Domestic cameras and recorders often use CBR (Constant bit rate).

    Has anyone bought one of these link below? it says TNTHD and freeview but does not say Freeview HD but DVB-T is shown and the tuner information in the spec. is HD/C which means very little!!

    :confused:

    Its suitable for reception of Irish DTT. Like France (TNT HD) we use MPEG4 on DVB-T. Of course it doesnt say Freeview HD.

    Why would it say anything about Freeview HD which would require a DVB-T2 tuner. The product is for the French market and will work for Irish DvB-T.

    Not correct my friend this product is sold in the E.U. not just France so as such
    these sets are useless so for people living in the border counties or N.I. as Freeview HD will be the standard there shortly so it seems they are dumping them on unsuspecting punters 'cos DVB-T2 will be the HD standard for the E.U. countries so similar to the dealers trying to fob off their Mpeg2 sets like those German supermarkets chains ,buyers beware!!

    WRONG, WRONG AND WRONG.

    John Dough you have been posting around here long enough to have a grasp of what is going on. I am shocked!

    Jeez. Tell me you understand what basic certification branding is for various countries! TNT HD is the certification for France.

    And that nonsense about dvb-t2 being the HD standard for Europe - WHERE did you pick that up ?????

    EACH COUNTRY has adopted their OWN PLATFORM and SPEC!!

    The majority of country WILL use DVB-T for MPEG4 HD! ONLY the UK use DVB-T2 for HD.

    Tell me you understand this.

    Finland, Sweden and Italy will also use DVB-T2 for HD, some other countries are running trials - almost all are DVB-T/MPEG-2 for SD.
