Blu Ray just not offer the benefits that DVD offered over VHS. People did not adopt DVD due to video quality, they adopted it for low price and convient features such as no rewinding / menus / and other stuff, standard stuff now\'a\'days.
believe it or not, one of the biggest reasons why many people adopted DVD over VHS is because of picture quality too, beside having convenient navigation menu and stuffs.
If picture quality isn\'t important, consumers would have accepted VCDs but they didn\'t. If navigation menu, and chapter skips, and no need to rewind are really that important to consumers. Then laserdiscs would have taken off because laserdiscs have those features.
but why didn\'t many consumers accepted laserdiscs? the number reason is the size of these disc is like 12" in diameter or 30 cm. Too big, in comparison CDs are only 3.5" or 12 cm.
And why didn\'t VCDs taken off since it\'s 12 cm which is more convenient to store than VHS tape? number #1 reason is picture quality.
VCD has the same resolution as VHS, which is 320 x 240. but VCD carries more resolution in color for channel blue and channel red than VHS, 1/4th of black compare to 1/16th of black that VHS carries. But because of compression quality back in the day isn\'t as efficient as nowadays and the encoder is MPEG-1. It does hurts the picture, which does have a lot of noticable compression artifacts. Second is, because its a digital signal which is precise, the picture looks really pixelated on 480i TV. Because 240 has to be output to 480i and with no good upscaler, it doesn\'t look good.
VHS on the other hand, doesn\'t have this problems because its an analog signal. it can ouput the 320 x 240i into 320 x 480i with no problems. No need to require a video scaler because its analog. it can interpolate those pixels into two and still comes out nicely with no pixelation. Also, VHS don\'t have any compression artifacts because its doesn\'t use any video compression like digital lossy video encoder does...
Also, there is this S-VHS format which doesn\'t get consumers acceptance either even though it has 560 x 420 resolution which is the same as laserdiscs. Sure the picture quality has 3.5 times more detail than VHS, but because it doesn\'t offer the convenience of menu nagivation, and the such. so, it bombed.
[SIZE="3"]So, that led me to believe DVD finally gained consumers acceptance because of picture quality, it\'s the same size as CD, and easier menu navigation.[/SIZE]what makes DVD picture looks so good is that DVD resolution is 720 x 480i or more than 4 times the resolution of VHS, and the 480i is the same resolution as NTSC so no need of a video scaler to scale to match the tv\'s lines like VCD does. Another big reason the more efficient encoder of MPEG-2. Another benefit is the dual layers that DVD can support. Which means it can store 3 hours or longer of a movie on a dvd disc than any older formats could like VCD, VHS, laserdisc...so no need to flip the disc, change disc, or change tape either...
