GMA Network continues to reject Japanese digital TV standard


MANILA, Philippines—GMA Network Inc. continues to buck the industry, rejecting once again the digital television standard developed in Japan, despite recent endorsements for the platform from all other major broadcast networks and government regulators.

In a statement, GMA Network admitted that it was currently conducting field tests using Japan’s Integrated Services Digital Broadcasting platform for terrestrial television (ISDB-T).

But the company remained unconvinced, saying it would not abandon its position favoring the second-generation Digital Video Broadcasting platform for terrestrial TV (DVB-T2), which it considered to be the best technology available in the market today.

“GMA continues to maintain its position that the country should adopt DVB-T2 standard over the ISDB-T, given the clear technical superiority of the European standard,” the company said.

GMA Network also said that while it was currently conducting tests utilizing the Japanese standard, “this does not mean that it has conceded its position favoring DVB-T2 nor that it has adopted ISDB-T.”

GMA earlier described the ISDB-T standard as inferior to the European platform, which offered lower power consumption and better data transmission.

The company likewise cited the more widespread adoption of the DVB-T2 standard around the world, which would result in better economies of scale that would bring equipment prices down.

ABS-CBN Corp. of the Lopez group has been conducting tests on digital TV since 2011 using the ISDB-T standard.

Manuel V. Pangilinan’s TV5 likewise started ISDB-T field tests late last year.

The Kapisanan ng mga Brodkaster ng Pilipinas (KBP) has also endorsed the ISDB-T standard, describing it as a better fit for the Philippines since the technology was developed in Japan which, like the Philippines, is a disaster-prone archipelago.

The National Telecommunications Commission (NTC) last month also expressed its support for the ISDB-T standard.

The NTC cited the lower prices of set-top boxes—devices needed by older TV sets to convert digital signals to pictures and sounds—giving the ISDB-T an edge over the European platform.

Digital TV broadcasting allows for the transmission of larger amounts of data over airwaves, promising cable TV-quality services for free-to-air TV subscribers.

    isn’t set up boxes for ISDB-T is more cheaper?

    • Iggy Ramirez

      Cheaper lang. Sobrang mura naman nun kung more cheaper pa.

      Mag canvas ka sa eBay ng ma check mo at huwag maniwala sa sabi sabi.

    • Clarence Rafael Gatchalian Alv

      Compared to DVB-T2, yes. It costs at about a thousand bucks and higher, pero the country is targeting set top box production so kaya pa bumaba ng hanggang 500 pesos ang basic STB.

  • John

     You know friends DVB-T2 is the best for us no need to get the Japanese standard balik na naman tayo doon sa NTSC and PAL /SECAM standard where the European Standard is more superior..

    Plus the equipments are easily available anywhere in the world.

    • Clarence Rafael Gatchalian Alv

      Ikaw na ang nagsabi na parang balik NTSC vs PAL na naman tayo… Pero what you don’t know (and the rest of the guys commenting here) is that DVB-T2 is based on PAL/SECAM analog transmission over 7- and 8-MHz television bandwidth (pero may 6-MHz din sila for DVB-T, hindi pa subok for DVB-T2)… and ATSC, as well as ISDB-T, is based on NTSC analog transmission over 6-MHz bandwidth.

      Kung titignan mo ang track ng lahat ng bansang nag-a-adopt ng kanya-kanyang standards, mostly European nations ang nag-adopt ng DVB-T/T2 dahil sa madali na lang ang conversion ng mga equipment and reception for television since they use PAL/SECAM, kaya masasabi mo na kaagad na marami ngang bansa ang nag-adopt ng DVB standard.

      Checking ATSC (the US DTV standard), typically North American countries, as well as South Korea, ang mga nag-adopt, which has all 6-MHz TV standard and adopts NTSC analog standards.

      So sa atin sa Southeast Asia, Philippines lang ang NTSC, the rest are using PAL. So technically speaking, we’re ought to use ATSC or ISDB-T lang. Pero DVB-T is also capable of transmission here in the country (due to some test ABS-CBN conducted way back 2007), pero para sa 2nd-generation DVB-T2, mukhang malabo pa sir sa mga kadahilanang:

      1. DVB-T2 is somewhat not tried and tested over 6-MHz TV band. Ika nga ng nai-comment ko earlier, mahirap nang mag-test nowadays due to lack of time before the full analog shut-off. Di sana nag-testing din muna ang GMA Network bago magsalita ng magsalita about sa T2. Puro kasi daldal.

      2. DVB-T2, as well as DVB-T, is not suitable for Philippine terrains, which attenuates easily compared to ISDB-T.

    Japanese companies lobbied this technology way-back on GMA’s Term. NTC insider confirm these, that they (Japs) pours billions of investment/under table just to get their ISDB-T, than DVB-T2 (European Standard), they even start planning/building the factory in Cavite and Laguna for mass production of set up boxes.

    Likewise, ISDB-T can be an Earthquake Early Warning (EEW) system. Three transmission methods can be applied to broadcast EEW as soon as it is issued in ISDB-T, in which AC transmission of an EEW can activate receivers and make people aware of its issue, even if they don’t watch the program. Now the only problem/hindrance that I’m seeing on this EEW transmission is the delay to display EEW due to the processing periods for compressing and decompressing video and audio data

    • Clarence Rafael Gatchalian Alv

      Pero sa kasalukuyan, EU delegates are now lobbying this DVB-T2, as my insiders also confirm. Ang totoo kasi, ang ISDB-T ay almost royalty-free standard, compared to DVB-T2 na kailangang bayaran ang EU once na na-adopt ang standard, hindi lamang ng gobyerno pati na rin ang bawat equipment related to DVB-T2 as per broadcaster at pati na rin ang bawat set top box na natatatakan ng NTC, if ever.

      Kung problema mo ang Emergency Warning System ng ISDB-T, well it has a merely less than a second of delay from activation. Kami sa DTV Pilipinas, nakita na namin ang ginawang tests ng PTV-4 for the EWS broadcast and it looks like how Japan is implementing it, pero at that time, test broadcast lang iyon at kulang pa for necessary information and data.

    i worked before in ABS, and i can vouch for this, that in tech, ABS ang nangunguna, they invest on this a lot. as for GMA, they develop their people more. so where do we go from here? we shall wait and see. but again, we are left behind from our foreign counterparts.

    • Clarence Rafael Gatchalian Alv

      Totoo sir, truth really hurts as GMA only test ISDB-T as this point in time… Napakarami nilang idinaldal kumpara sa pagtesting ng both standards, to think na yung pinagpipilitan nilang DVB-T2 eh hindi pa nila nasusubukan hanggang ngayon!

  • Kilabot ng mga Balahibo

    saan ba gawa ang binibili nating tv? ano mas cheaper? buy a tv from japan with its ISDB-T or DVB-T2?

    lets get economy as a factor.

  • Vertumnus

    I doubt consumer cares whether their service provider uses DVB-T2 or ISDB-T as long as they have clear pictures and cable rates don’t cost too much.

    • brunogiordano

      “Digital TV broadcasting allows for the transmission of larger amounts of data over airwaves, promising cable TV-quality services for free-to-air TV subscribers.”

      Free to air tv hindi mo na kailangan magpakabit ng CABLE TV.

      Clear at sharp ang mapapanood mo. Sa DVB-T2 mas maganda.

      Magagamit mo pa rin ang kasalukuyan mong TV para maka receive ng DIGITAL TV pag bumili ka ng SET UP box.

      Kung hindi analog pa rin ang mare receive mo.

    I am less knowledgeable insofar as anything about digital TV standard or whatsoever is concerned. However, I noticed one thing while watching TV. While GMA programs remain smooth and clear while a plane passes by, ABS-CBN’s and TV5’s become shaky and blurry. Kung may kinalaman dito ang 2 standard na ito na ginagamit o tinetesting ng 3 networks,GMA is right for sticking to the standard it is currently using. Ang ganda ganda at napakalinis ng reception sa GMA7 at NEWS TV kumpara sa ABS-CBN at TV5.

    • JanB

      Roland, Analog pa ang ginagamit ng Tatlo sa ngayon…Wala pa ang digital transmission na STD na sinansabi. Although, BAS-CBN already starrted distributing the so CALLED BLACK-BOX”…ito po yon…pero limited pa lang po ang meron nito… DEVANT LCD led TV HAS built in support tuner already on some models sa pag kaka-alam ko…  

    • Clarence Rafael Gatchalian Alv

      Sir, sa digital terrestrial television, wala nang interferences caused by nearby frequency-emitting devices and objects. Mahirap i-explain thoroughly pero kung sa analog TV, yung snow ang kalaban mo kapag mahina ang reception, sa digital TV, ang pagpi-pixelate ang kalaban mo sa mahinang reception… Just as you’ve tried SkyCable Digibox..

  • Echuserang_Froglet

    grave ha may nanunuod pa ba ng gma 7? ppppppppwwweeeehhhh kadiri eeeeeeeeeeewww

    • Alim Labixa

      ahole. the lopezes are crooks so that makes them eeeewwwww.

    • Rygee

      Hahahahahaha bayaran!!!!!!!!!!!!!

  • akoombulator

    anong kinalaman ng mga disaster sai klase ng digital tv standard? labo mo men

    • Nothandsome Nottrue

       kailangan ng japanese standard dahil sa disasters dito sa pilipinas. kasi pag may bagyo walang kuryente, so kailangan japanese standard para makapanood ng tv. teka lalo yatang lumabo hahahaha

      • Kilabot ng mga Balahibo

        Reminds my why life guards tell people to get off the swimming pool during storms.

        So they wont get wet, silly… ahahahahaha.

    • Kilabot ng mga Balahibo

       guess lang po.

      baka kasi affected ang tv signal kapag may strong winds. as mentioned above, pag may dumaang eroplano, minsan nawawalan ng signal ang ibang tv stations.  So could the constant streaming of charges in the air (which causes lightning) may affect broadcasting. And with that, you need a reliable medium of disseminating info during crisis.

      • Nothandsome Nottrue

         tinatangay ng hangin ang signal hahahahahahahahahah ahahahahhahahha hahahahhaha

      • Kilabot ng mga Balahibo


      • Bojo Mojo

         hahahaha! funny! sakit ng tyan ko tuloy…

    • Clarence Rafael Gatchalian Alv

      Siguro sir ako na lang sasagot ng MATINO sa katanungan mo… Disasters sa Japan ay napaka-vulnerable na laging binabagyo at nililindol ang Japan…

      Sa ISDB-T, may Emergency Warning System sila na feature, kung saan magse-send ng warning signal/alert ang nearby broadcast station sa lahat ng devices na may TV (kahit nakapatay, basta nakasaksak sa kuryente), even pati yung mga cellphones nila na may “1seg” feature (mobile TV)…

      In fact, yung recent lindol at tsunami sa Japan noon, nakapagligtas ng mga mamamayan nila dahil lang sa ISDB-T EWS alert. As of now, nakapag-test na ang government station PTV-4 ng EWS, which is sila ang magke-carry ng EWS alerts since then, in coordination with PAGASA and other gov’t offices.

    Sang ayon ako sa position ng GMA.

    Ang set up box para sa ISDBT-T ay mas mahal at kaunti lang ang mga pamimilian dahil iilan ang nag adopt ng ISDB-T sa buong mundo.

    Try ninyong mag canvas sa EBAY at tignan ninyo kung sino ang nagsasabi ng TOTOO.
