Multimedia, AV An interesting anecdote at MinimalMac about television being broken. The author's young daughter, who is growing up in a Netflix/Hulu/iTunes/etc. household, was confronted with actual TV for the first time, and wonders why she can't pick what to watch, why the shows are being interrupted all the time, and so on. Clearly - TV is broken.

Upscaling (and for that matter, transcoding anything to higher bitrates) will _never_ improve quality. The absolute best you can hope for is the same as your source.


Sorry, but that is simply not true in all cases. Upscaling (as the OP was using the term) has nothing at all to do with bitrate or improving the quality of the source material - it is about preparing it as best as possible for the screen it will be presented on.

Most older HD TVs simply enlarge the lower resolution image of a DVD to fit the screen size by performing simple block scaling. This works but generally looks horrible, and the larger the screen the worse it looks.

TVs or DVD players that perform "upscaling" are using much more sophisticated interpolation algorithms to perform the scaling, as well as usually performing motion compensation to correct issues that arise during scene transitions, etc.

Also, if you are preparing DVD material for display on a 1080p screen, transcoding it to 1080p resolution can improve the picture quality relative to the original DVD - it depends on the TV it will be displayed on. It isn't a matter of bitrate, it is simply compensating for poor scaling circuitry in the TV. Granted, most current HDTVs have very good scaling performance - but if you have an older one the difference can be quite dramatic.

Just saying, it is not always pointless.
