GMA-7 May Still Offer To Broadcast SD In DTT This 2011

While a rampant Japan Surplus in an ordinary public places have often tuned to Channel 7 at all TV sets causing an interference of legitimate Mega Manila Household TV Meter System, as well as the trend of controversial claim of intent rising growth of audiences in Mega Manila People TV Meter System started in 2010 not only in households but also outside household TV viewing in establishments and public transport, I already thought about the advantage of strong analog terrestrial TV signal of Channel 7 of GMA Network even with (a cheap indoor) or without (indoor or outdoor) TV antenna for ordinary household and public places, compared to other analog terrestria TV channels that require only outdoor antenna in order to pick up signal even at far distances due to limited power signal transmission. Although Channel 7 have often generate crystal clear video detail in 525-line (480i) NTSC format, it often encounter multipath signal such as “ghosts” due to obstructions in buildings and “fuzz-out” video signal when the vehicle, such as bus unit, is moving due to Doppler effect referring between analog TV transmission and reception.

And while ABS-CBN, GEM TV, and NBN have already purchased HDTV broadcast equipment, GMA Network may not yet ready to broadcast HD format due to constraints of their financial needs in order to buy new equipment, but it may be still opt to broadcast SD format momentarily for the next few years even for the recent adoption of ISDB-T based digital terrestrial television (DTT) in Philippine shores this mid-2011. (The Japan-based ISDB DTT system–compared to ATSC and DVB-T–has greater advantage to receive both fixed and mobile digital transmission without jamming out DTV signal called “garbage” in video.)

And aside from datacasting and Emergency Warning Broadcast (EWB) as an important feature of ISDB-T that is now mandatory according to the nearly completed Implementing Rules and Regulation (IRR) from National Telecommunications Comission (NTC) by June 2011, the Japan-based DTT system may accomodate five subchannels per 6 MHz carrier TV channel, not only in current DTT broadcast such as GEM TV and NBN as well as ABS-CBN and ABC-5 coming soon but GMA-7 should also include to broadcast digitally away from power-hungry analog TV transmission power in order to accomodate two affiliated analog TV channels (GMA-7 and GMA News TV) as well as the (1) possible revival of QTV and (2) introduction of radio TV channels DZBB and DWLS in the future, almost free viewing at all!

By the way, I would rather wish to suggest for consent that GMA-7 may focus first to purchase a fairly cheap ISDB-T DTT transmitting amplifier supporting both SD and HD DTV signal and then install a DTV transmitting antenna prototype such as Jampro below a current analog TV transmitting antenna at various GMA-7 TV tower facility in Metro Manila and provincial stations. In spite of taller TV tower structure that would be dangerous to humans if exposed of producing a harmful gigahertz (GHz) electromagnetic RF microwave signal used in cellphones and satellite just as possibly true to the use of UHF RF signal (470 MHz to 890 MHz), it is important to limit DTV transmission power by 1% of current analog TV transmission in order to save electrical consumption, as well as designating a lower TV channel value such as a rumored Channel 27.

And for most loyal televiewers who hate to buy ABS-CBN based DTT unit whether tuner box or handheld, they may prefer to other unit that can access only freeviewing DTV channels such as GEM and NBN, including ABS-CBN, ABC-5, and GMA-7 broadcasting soon. They should also forget to use analog TV giving a way for a full shift to freeviewing DTT because of advantages of picture clarity without multipath video reception.

If GMA-7 would promise to adopt freeviewing DTT broadcast for its loyal televiewers around Mega Manila, expect that the network would increase about 20% to 30% of available TV audience over entire future GMA-7 TV shows per day in People TV Meter system by 3rd quarter of 2011 to 2012 only if they would use both handheld and “tuner box” DTT devices, according to my own forecast.

    You may be right about it but the GMA can broadcast in HD since the Philippine ISDB-T will use MPEG-4/AVC for video broadcasting which gives way to 2 HD channels which can be used for both GMA7 and GMA NewsTV.

    There is no need to broadcast 2 radio stations with GMA’s ISDB-T lineup since we have HDRadio as a digital terrestrial radio standard which can give up to 7 subchannels in AM and FM band.
    AM can get the quality of FM radio while FM can get the quality of a CD or MP3.

    GMA Network, if they were to balanced the debt and expenditures, should matter to gamble with the current and in-demand services of the past. Remember ANC’s dominance for 15th years, the ABS-CBN News Channel happened now to be the most premium news channel of the Philippines, at par with BBC and CNN.

    To think they’re going to have a radio-TV service for its DTT, I think they should do the upgrades first before catering another channel.

    And GMA is still not in the prepping stone to have their own DTT service this 2011. Expect it by 2012 or later. TV5 is expected to be next with UNTV’s readiness with DTT. Mark that.

    Another. 1% of its analog power would have GMA DTT use only 1.2 kilowatts? Darn it. They couldn’t conquer the suburbs, or even reach Tagaytay Highlands with that power for DTT, with competing power of ABS-CBN DTT having 10-15kW of power in the future.

    HaHa! it seems Albcor has run out of power. May be you should use the digital topo to sharpen your mind.

      Think again, this is a very crucial point for our country that there is one (and another one? I don’t know) contrary to the Japanese system and there again the DVB Team lobbying again in our country.

    Can’t see any problem with a high tower transmitting high frequency at GHz.. I often seen it on your writing. For me, it is more favorable for a transmitter to have a high antenna tower to have a wider reach. Another is that a higher tower will tend to lessen the exposure hazard for people under the tower. Remember the inverse square law.
