With HDMI you dont Need a Multi-System Video Converters

A USA standard TV screen with a built in High Definition support (DMI port) will work with any cable TV service in Tanzania that transmit HD signal. You don't need to use a PAL to NTSC video converter because HDMI format is independent of both those standards. I researched on this and decided to buy a flat screen from the US, where the latest TV technology is available at a comparatively lower price. It worked perfectly!

I have also been told by mshikaji wangu at DSTV kwamba soon wataanza kuuuza cable box zenye HDMI ambazo zitakuwa very cheap – less than $100. The only downside to this is that, you have to be on DSTV (or other cable service that transmit HDMI signal) to use NTSC TVs in Bongo. Regular air-wave reception are on PAL so you will still need a converter!

I hope this will help someone…

mnh sijaelewa kaka hdmi ina mahusiano gani na ku convert, sababu ninavyojua hdmi ni waya kama waya zengine ambayo kazi yake ni kupitisha data.

Kaka, ninacho jua mimi ni hivi;
Sigal zote za TV zina beba both audio na video (na information nyingine ambazo zinahitajika kwenye signaling). System ya PAL na NTSC zina define how color information is to be carried (encoded) on a TV signal. kwasababu PAL wana encode color tofauti na NTSC, basi hizo signal aziingiliani mpaka uwe na converter. Pia, kuna issue za timing amazo PAL hutegemea umeme wenye frequency ya 50HZ, wakati NTSC hutegemea timing kutoka umeme wa 60HZ.

On the other side, color coding ya High Definition haiku based on PAL or NTSC, bali is the same for any TV that can decode the HD signal. I believe HD ina tumia encoding scheme ya H.264/MP-4 ambazo ni digital standards ….
Kwahiyo kama TV yako in HDMI basi inaweza decode HD color format, which is independent of PAL or NTSC across the world…

Also, kumbuka kwamba any communication cable zina define a particular communication protocol na kila wiring pin kwenye port in kazi yake according to that protocol, which in this case it is HDMI port. Ukisha ingiza signal kupitia HDMI port basi umo ndani ya TV kuna decoder circuit ya HD iamabyo inafanya kazi ku-reproduce rangi; mpangilio wa rangi ambao hauko based on PAL wala NTSC.


I hope nimefafanua zaidi …sorry niliyasoma analog/digital transmission more than 20 years ago!
