MPEG2/4 and Sony
Roman Rumian - 2012-03-17 06:01:00
Dear Friends,
what is the contribution of Sony to MPEG2 or MPEG4 video standard ?
How do this company participate in the benefits of these standards ?
Could you give me a short answer ?
Thank ...

Randy Yates - 2012-03-16 18:28:00
Hey Guys,
Long time no see, huh? Sorry, but I've been busier than a one-legged
man in an ass-kicking contest lately.
Hey, I've got a DSP theory question. It may be obvious and I'm missing
the ...Recommend a faster responding Low Pass Filter than a 2nd Order Butterworth? [14 articles]
andrew66 - 2012-03-16 14:07:00
I have a signal that generally lasts about 6 seconds and has a lot of
Low-Frequency, < 10 Hz, noise in it. I would like to use a filter to
obtain a reliable answer for the mean value of the signal, ...Phase of DC component of FFT [3 articles]
westocl - 2012-03-16 13:28:00
With the FFT the first bin is the dc component. What are the implications
of the 'phase' of that bin?

jacobfenton - 2012-03-16 01:47:00
Suppose you have a classical 2nd order PLL, but instead of having a linear
error curve, with a slope you can determine, you have essentially a slope
of 0, which means that you can detect error, but on...Lytro [3 articles]
glen herrmannsfeldt - 2012-03-15 13:54:00
After seeing discussino of the Lytro light-field camera, the
first thought I had was that DSP would be pretty important in
making it work. Yet I don't remember seeing any discussion of it.
The ar...Coherence and Cross Correlation [10 articles]
ayeriera - 2012-03-15 12:00:00
Dear all,
I have a simple question that I am trying to confirm, but could not find
any clear answer yet.
If I want to compute the coherence of two signals (EEG signals in my case)
in a particula...OT: C macro to declare u32 from "ABCD" [11 articles]
Andre - 2012-03-14 20:51:00
Dear all,
I would like to handle a table of 4-byte long strings by just declaring
them as an array of unsigned 32 bit values.
Of course, this can be done manually, but it would be great if a mac...unclipping [15 articles]
glen herrmannsfeldt - 2012-03-12 03:51:00
I have a digitized WAV file about 71 minutes long (actually, 10
files totaling 71 minutes) with three samples clipped, I believe
not all consecutive.
I can't actually hear them, as I usually can...LDPC - Parity Check Matrix , using: cyclpoly & cyclgen
wuid - 2012-03-11 11:28:00
Hi all,
i tried this for arbitrary matrix size:
%%%%matlab code
pol=cyclpoly(rows,cols); h=cyclgen(cols,pol); henc=sparse(h);
l=fec.ldpcenc(henc)
by doing that i am able to encode my msg wit...
