Knowing Too Much

I heard an old, familiar song on the radio this morning. But something about it was off, and I knew what. I found myself yelling at the radio, “Use a higher bitrate!” For you see, the chorus of the song exhibited something that sounded like the notorious “underwater” artifact in MP3 when encoding with too low a bitrate.

I remember first hearing perhaps 10 years ago that radio stations were starting to move all of their music to MP3 (prior to that, I remember hearing that some would have a stack of about 10 CD players with music queued up; who really knows? And I’m sure varying radio stations use different equipment and setups). I just assumed that a radio station would use the highest bitrate possible. Perhaps this particular encoding was a leftover from when the radio station first moved to MP3 (the song itself was from 1995), when they assigned an intern to use some shareware encoder that was only capable of 96 kbps MP3.

I know I can’t be the only multimedia geek who gets frustrated at seeing sub-optimality deployed in the world at large. I remember staying at a hotel during Christmas of 2000 (the same year I was just starting to study multimedia) where the in-hotel movie preview system through the TV displayed horrible blocking artifacts. At the time, I only vaguely understood what could have been going on.

The Women Of Webhosting

Some of you may have noticed that the various websites hosted here on multimedia.cx were having a tad bit of difficulty recently. Long story short: My previous web host was having some serious problems and I decided it was time to ditch them and move on to a better one. Fortunately, I had (and continue to maintain) consistent, automated backups of everything hosted on multimedia.cx. But I really wasn’t looking forward to the task of finding a new provider. Whenever I have studied web host providers in the past, they all seem pretty much the same– offering UNLIMITED EVERYTHING!! along with perfect uptime and reliability for next to nothing(*** see details below in 5-point font). And most of their websites boast a design style reminiscent of the worst e-marketing sites and guaranteed to annoy the utilitarian, tech-savvy geek.

When it boils right down to it, I think I was being asked to make a decision regarding a new web host based on the female smiling at me on the front page. Honestly, these photos were generally the only distinguishing feature among the various services:

Capturing DV Screenshots

I have a specific task I need to do: I need to view a DV stream captured from an NTSC video source via DV bridge and capture screenshots. Since there is a lot of footage, I need to be able to seek easily through the stream (not unreasonable since DV is purely intra-coded, i.e., it consists of independently coded keyframes). Since this is television source material, I want the data competently deinterlaced while viewing and certainly when the screenshots are taken. One more thing — I want the screenshots to retain their 720×480 resolution that looks correct on a computer monitor, and not be squished down to 640×480, overscan region and all.

If you must know, it’s because I play lots of games for my Gaming Pathology project and contribute data for them — including screenshots — to the MobyGames database for posterity. I have a huge number of console games yet to cover and the screenshot dilemma is one thing that is holding me up. Consider the need to properly preserve representative screenshots of the Sega Saturn version of Space Jam for future generations of video game historians to study.

Måns Got A Gdium

I lost the thread on those pre-release Gdium netbooks sometime ago. After being accepted into the One Laptop Per Hacker program, I responded affirmatively but never heard anything else. So how did Måns Rullgård manage to get ahold of one?

It’s all good. Check out the link to his blog for all the surface details of the OS and default software. The important thing is that we have a computer with a MIPS 64-bit CPU in the FFmpeg developer community. It should only be a matter of time before the unit starts serving FATE duty alongside the Alpha in Måns’ flat.
