TV Compatibility

[freeier]

hi,

ok one question, what is the compatibility of TV purchased in hk overseas ?

i guess japan is out. but can flat screen bought in hk over the past 1-2 years be used in singapore ? what is the frequency range impact.

i know my friend took a CRT tv from sg to hk and it was not really usable for the standard channels but it was ok for the cable.

cheers

The three world television standards are NTSC, PAL and SECAM.
NTSC - National Television Standards Committee, 525 lines, 30 frames per second. This is the system used in America and Japan
PAL - Phase Alternation by Line, 625 lines, 25 frames per second. This is the system used in the UK, Hong Kong and Singapore.
SECAM - Sequence de Couleur a Memoire, 625 lines, 25 frames per second. This is the system used in France.

ok. so it sounds like hk and sg is common.
my fren were only able to see vision and no sound when he brought his CRT to hk.

Can't say why your friends TV didn't work the theory is that they are fully compatible although I haven't actually tested it myself. I know am know a man who has though, I'll ask him ASAP.

There's more than one version of PAL - they differ in the frequency offsets of the audio channels. Singapore uses PAL-B/G, HK uses PAL-I. A multi-system tuner will work in both places either automatically or it may need a manual setting in the menu structure somewhere.

hey Freeier my friend confirms what PDLM says there are different versions of PAL which affects the audio. But you can buy a multi system TV in Singapore also known as a TV with international multiformat and that gets round the problem.

errr.. 8-P
my issue now is bringing back an existing flat panel tv purchased in hk back to sg. so the conclusion is that the freq offset is different and it won't work ?
any way i can put an external LO and force it to modulate in the correct frequency ? 8-)

well, as you can see, technically i am an electronics engineer. but i guess i'm just too far away from the actual practical usability matrix. so bombard me with the necessary jargons i'd understand but essentially i have to figure out if i should bring the tv back home!

Have you considered RTFM?

Or, incase you don't have the M ... let me know the model number. Have a friend who has tons of these manuals scanned and should be able to check compatibility.

To be honest, virtually anything made by a major manufacturer will be compatible between HK and Singapore. Both the markets are too small for them to have a different production line for them individually.
