| DoubleAnalFan Member 50 Posts 11/04 | Hi guys. I'm a tech noob. I'm thinking about getting a HD-TV. I just bought a DVD player that upscales SD to look more "HD". I'm wondering whether it's true. Am I really going to see a discernable difference on a HD-TV by upscaling SD pornos? Anyone have any experiences with this? Thanks in advance. [Link] |

The upsampling processes takes place in chipsets working on heightened frequencies, providing extended signal bandwidth, accommodating filtering/ manipulating all kind of (unwanted) data-related signals (noise, harmonic distortion, picture non-linearities) out of the video signals (and interpolatating new/ desired data), without SD's frequency limitations. These chipsets are more vulnerable for non-optimal board (PCB) layout/ less-then-stable clocking/ high frequency interference (non-optimal screening) and so on, making 'upsampling' not a general magical trick. Poorly executed, it will create nasties like macroblocking and smearing. When done right, I can say without hesitation that a well encoded (SD-)movie will look just stunning on a HDTV (poorly encoded it will not look that great, but that is just because the DVD player will show these imperfections a lot more due to the higher quality display connected). There are substantial benefits upconverting SD material to 720/1080 on a HDTV: in general positively more crisp and detailed, with a more natural and non-fatiguing picture than probable thought possible from SD-DVD's. Not 'true-HD', but upconverted SD-DVD signal, via HDMI/DVI or component-video onto a HDTV screen is absolutely higher-def: very worthwhile doing IMO. p_n |
| DoubleAnalFan Member 50 Posts 11/04 | Thanks again. I ask, because I'm watching Throat Gagges 4 with a Sony DVD player on a CRT Panasonic (3 year old model). And I'm noticing that background objects, such as couches and tables, are not very well defined. What's more, sometimes their blurriness shifts into what looks like a more precise image. The shifts last less than a second; I'm wondering if upscaling would correct such a problem. |
| pinc_noiz Deactivated User 758 Posts 6/05 | Besides, the blurriness you noticed when watching Throat Gaggers 4 can be related to both the filming/recording technique and the disc-manufacturing process used for this DVD. Please take note, faults in content and/or production of DVD's can't be corrected by upconverting (when upconverting corrupted data, the new data will be corrupt too ...). BTW; I read 'upscaling' in your posts too: as this is done by fixed-scaling (like 2x3=6) this will hardly add anything on picture-quality. 'Upconverting' uses intelligent software to make up/ fill in needed data (the 3...5's to get from 2 to 6 in this numerical example): when done right this will add on picture-quality. p_n |
