fair use, copyright, license thoughts

Posted on February 28, 2010 at 2:32 PM

fair use, copyright, license, sync here's a note from another thread that got started. Thought it might be good to post it here as well.

There are discussions within fair use for educational and documentaryuse in specific circumstances that you can use 10% or 30 seconds.EXAMPLE

"Use 10% of a song, not to exceed 30 seconds, and donot show the finished video out of the classroom. Do not duplicate,distribute, broadcast, webcast or sell it. Proper attribution mus...

more on cable seletion... This is some of ESP's comments that I find interesting and agree with from my past work in Communications, RF and engineering.

Interconnects

All well designed interconnects will sound the same. This is acontentious claim, but is regrettably true - regrettable for those whohave paid vast sums of money for theirs, at least. I will now explainthis claim more fully.

The range (and the associated claims) of interconnects is e...

More on cable selection and design HERE's ANOTHER!

How big should the conductors be?

The required size (or gauge) of the conductors depends on threefactors: (1) the load impedance; (2) the length of cable required; and(3) the amount of power loss that can be tolerated. Each of theseinvolves relationships between voltage (volts), resistance (ohms),current (amperes) and power (watts). These relationships are definedwith Ohm's Law. The job of a speaker cable is to move a...

tri-level bi-levle sync SD and HD are 2 different standards.

Posted on February 28, 2010 at 1:01 AM

tri-level bi-levle sync SD and HD are 2 different standards. They require two different types of sync.

SD bi-sync and HD tri-sync are different signals.

SD Bi-sync supports computer video, composite video, s-video, andcomponent video, by using 2 voltage levels ( high and low )... systemsusing bi-syn are triggered by the differential voltage at the leading (negative) edge of the signal. Bi-sync basically runs at 0 votage (black) then drops to a negative volt...

Stereo downmixes (or fold-downs)

Posted on February 28, 2010 at 1:00 AM

Stereo downmixes (or fold-downs)

Left total/Right total (Lt/Rt)

Lt/Rt is a downmix suitable for decoding with a Dolby

Lt = L + -3dBC - -3dB(Ls + Rs)

Rt = R + -3dBC + -3dB(Ls + Rs)

(Ls,Rs 90-degree phase shifted)

Left only/Right only (Lo/Ro)

Lo/Ro is a downmix suitable for stereo playback

Lo = L + -3dBC + attLs

Ro = R + -3dBC + attRs

(att=-3dB or -6dB or -9dB or 0)

5.1 downmix

BEYOND DOLBY DIGITAL

There is little sense in having an emission coding system such as DolbyDigital (AC-3) that can carry 5.1 channels of audio if you can't get5.1 channels to the encoder. In 1996, all commonly used VTRs had onlyfour audio channels; servers could in theory do more but were notgenerally configured that way, and digital plants rarely had more thantwo AES pairs available for routing. Once the Dolb...

CONVERSION of Audio for PAL / NTSC / FILM

Posted on February 28, 2010 at 12:54 AM

Some notes on CONVERSION of Audio for PAL / NTSC / FILM Ifthe PAL version was a frame-to-frame transfer, and is thus runningfaster than the original film (25fps vs 24, or even PAL video at 25 andHD video at 23.98), the key is to first get your stems back up to filmspeed, which would involve an SRC using 47952 as the source samplerate. THEN, when it's back at film speed (48k), you could do theNTSC>PAL SRC, the 4.1% thing. Maybe? Try just the center channelusing the fastest setting as a...

Frame Rate Info

Posted on February 28, 2010 at 12:53 AM

Frame rate is the rate at which videoplays back frames. Black and white video ran at a true 30 frames persecond (fps). When the color portion of the signal was added, videoengineers were forced—for various technical reasons related to thephysical circuits—to slow the rate down to 29.97 fps. This slightslowdown of video playback leads to distortions in the measurement ofvideo vs. real time. Video is measured in indivisible units calledframes. Real time is measured in hours, minutes...
