marami na ring may gusto ng ISDB-T. merong isang malaking broadcast company na nagte-test ng DVB-T dati pero ang huling dinig ko ite-test naman nila 'yung ISDB-T. ;D magiging patok siguro 'yung TV Tuner (Oneseg) para sa PSP niyan kapag ISDB ang in-adapt. ;D

parehas lang din, may horizontal at vertical dahil 'di naman sigurado kung ano alignment nung antenna ng receiver.

Yun nga sir,Talk to some ABS engr's. malamang daw ay ISDB-T ang i adopt natin mga after election i announced na ng NTC kung anong platform ang gagamitin and they are now conducting some testings. maybe one of this days I maybe able to do the testings with them,We will test if conventional antenna can be efficiently use to receive digital signals,mas ok daw kung vertical polarization

Mas maganda sana kung dvb-t para we can conform to the rest of the world.  Yung sky cable digital ano ba gamit dun,  dvb-c rin ba?  Ang sattellite reception kasi ngayon eh dvb-s gamit globally.

marami na kasing nagpu-push nung ISDB-T kahit na previously DVB-T ang gamit nila, nakakita pa nga ako ng multiple DVB-T boxes sa office nung broadcast station, tapos gusto na rin pala ng ISDB. ;D

ok lang naman 'yung conventional antennas. meron lang pwede sa loob ng bahay like fractals, then meron ding decorative antennas.

pero 'di mo pa rin maaalis na dalawa ang polarization, 'di naman nila masasabi na dapat patayo 'yung antenna ng viewers. paano na 'yung mga mobile, dapat patayo rin lagi ang antenna. ;D

yung GEM-TV nagtetest na ng digital tv gamit yung ISDB-T kung mayroon kang receiver ng digital signal masasagap mo yun

Based dun sa mga slidesets. mukhang mas maganda at mas bagong technology ang isdb-t.  I just hope this dvb-t and isdb-t don't end up like the vhs-betamax wars of the past.

AFAIK, dati DVB-T na talaga ang gusto ng NTC, pero nung nagkaroon ata ng shuffle sa NTC, doon nagkaroon ng option na i-evaluate ang ISDB-T.

dati nung sinetup namin sa school gamit namin yagi-uda antenna kahit medyo panget pagkakagawa at sinabit lang sa may alambre maganda pa rin yung sagap ng signal galing sa GEM-TV ;D


ang maganda sa ISDB-T pabor lalo na sa bansa natin na daanan ng mga kalamidad

Log-Periodic. constant SWR and impedance over the range, at wide bandwidth. maliit lang ang footprint nito kahit na 5 to 7 elements pa.

tapos sa indoor antenna, Fractals.

BTW, 'yung Log-Periodic, Fractal antenna rin talaga.

Nag search ako sa internet...check this http://www.dvb.org/. Di ko ga'no familiar dito, pero do you think by 2015 ma-aadopt na natin eto? Maraming pang analog tvs at yung iba pa nga eh na-re-repair pa kahit 'vintage' na. Ibig bang sabihin nito lahat ng tv dapat magiging digital na...Need na talaga to 'upgrade' my knowledge from what I learned from school years ago
Isama nyo na rin ito... http://en.wikipedia.org/wiki/List_of_digital_television_deployments_by_country
