We recorded this DVD in Santiago de Chile, on NTSC. If it would have been superb quality (PAL) and
top notch equipment that we were after, we would have recorded in Amsterdam or another big city in Europe.
From Wikipedia:
"PAL, short for Phase Alternating Line, is a colour encoding system used in broadcast television systems in large parts of the world. Other common analogue television systems are SECAM and NTSC."
"NTSC is the analog television system in use in the United States, Canada, Japan, Mexico, the Philippines, South Korea, Taiwan, and some other countries, mostly in the Americas (see map). It is named for the National Television System Committee[1], the U.S. standardization body that adopted it. It is frequently but wrongly called National Television Standards Committee. The original document at the Library of Congress is clear in that respect[1]."
PAL vs. NTSC:
Because the PAL format has greater resolution than NTSC, it is generally accepted as being of higher quality.[2] NTSC receivers have a tint control to perform colour correction manually. If this isn't adjusted correctly, the colours will be faulty. The PAL standard automatically removes hue errors by utilizing phase alternation of the colour signal (see technical details), so a tint control is unnecessary.
However, the alternation of colour information — Hanover bars — can lead to picture grain on pictures with extreme phase errors even in PAL systems. Usually such extreme phase shifts do not occur; this effect will usually be observed when the transmission path is poor, typically in built up areas or where the terrain is unfavourable. The effect is more noticeable on UHF signals than VHF as VHF signals tend to be more robust.
A PAL decoder can be seen as a pair of NTSC decoders:
* PAL can be decoded with two "NTSC" decoders.
* By switching between the two NTSC decoders every other line it is possible to decode PAL without a phase delay line or two phase-locked loop (PLL) circuits.
* This works because one decoder receives a colour sub carrier with negated phase in relation to the other decoder. It then negates the phase of that sub carrier when decoding. This leads to smaller phase errors being cancelled out. However a delay line PAL decoder gives superior performance. Some Japanese TVs originally used the dual NTSC method to avoid paying royalty to Telefunken.
* PAL and NTSC have slightly divergent colour spaces, but the colour decoder differences here are ignored.;
* PAL supports SMPTE 498.3 while NTSC is compliant with EBU Recommendation 14.
* The issue of frame rates and colour sub carriers is ignored in this technical explanation. These technical details play no direct role (except as subsystems and physical parameters) to the decoding of the signal."
CONCLUSION:
PAL and NTSC dont have
necessarily to do with image quality, only format.
Therefore, thats not the correct answer to why the image is crap.
