Hmm... does it mean that the LCD screen does not have an improving
effect on the reception?
I have watched TV overseas and had noted that the flat screen LCD
gives better picture quality than the CRT.......

The quality of reception depends on the available signal and the
quality of the antenna and download.

Analog signals are more prone to detoriation of picture quality
due to bad reception eg ghosting, snowy noisy pictures, than digital
which is either all or nothing with a very narrow in between state
of pixellation and picture freezing.

But it all depends on the picture source.

If for example you have a Blu-Ray player and connect it to a large
screen LCD TV via HDMI (a digital cable thereby enabling transfer of
the High Definition picture) it is going to look far better than if
it was connected to a CRT via a SCART or S-VHS vable (an analog
cable with maximum resolution of NTSC only).

Incidentally, if you show a poor quality digital source, eg
too low bit rate tv program on a large screen, the digital
artefacts are much more apparent than on a smaller screen --
eg the grass on the soccer pitch just looks like a smooth
green billiard table and there is no detail and fast movement
may appear as pixelated blocks.

So LCD screens do not magically make bad video sources look
better.

If you are in the Philippines were the current system is as far I am
aware a variation on NTSC, then your only option for viewing TV on
your laptop is an analog TV USB device.

And according to

<http://wapedia.mobi/en/Television_in_the_Philippines#3.>

when the Philippines does change over to digital TV, it will be
as per the decision of the NTC.
