EMDTV(4) BSD Kernel Interfaces Manual EMDTV(4)NAME
emdtv -- digital video driver for Empia Technology EM28xx based cards
SYNOPSIS
emdtv* at uhub?
dtv* at dtvbus?
DESCRIPTION
The emdtv driver provides support for digital video cards based on the Empia Technology EM28xx series of DTV interface chips (in particular,
the EM2883). This chip is used in USB products.
Supported cards include:
Device Demodulator Tuner
ATI TV Wonder 600 USB lg3303(4)xc3028(4) (XC3028L)
The XC3028L digital tuner requires firmware. This is provided by the pkgsrc/sysutils/xc3028l-firmware package.
SEE ALSO dtv(4), dtviic(4), usb(4)HISTORY
The emdtv device driver first appeared in NetBSD 6.0.
AUTHORS
The emdtv driver was written by Jared D. McNeill <jmcneill@NetBSD.org>.

DTVIIC(4) BSD Kernel Interfaces Manual DTVIIC(4)NAME
dtviic, au8522, cx24227, lg3303, mt2131, nxt2k, zl10353, tvpll, xc3028, xc5k -- Inter IC (I2C) modules for DTV
DESCRIPTION
The dtviic modules provide support for dtv(4) devices. The dtviic module group includes tuners, demodulators, and analog video decoders.
The usual hardware structure consists of a host controller (connected for instance via usb(4) or pci(4)) that provides the data moving facil-
ities (for the analog or digital video streams) and an iic(4) bus over which the other chips can be configured.
For example, a typical dtv(4) setup would look like this:
1. Initialize transport stream (TS) port on the host controller.
2. Configure the demodulator that ``demodulates'' the information from an intermediate frequency (IF) that is provided to it by the
associated tuner. This step typically includes setting the desired quadrature amplitude modulation (QAM) and bandwidth, among
other things.
3. Configure the tuner. Typically this step includes at least setting the frequency.
4. Start TS transfer (using DMA transfers or USB high speed transfers).
The supported demodulators include:
au8522 Auvitek AU8522 ATSC/QAM64/QAM256 demodulator
cx24227 Conexant CX24227 ATSC/QAM64/QAM256 demodulator
lg3303 LG LGDT3303 ATSC/QAM64/QAM256 demodulator
mt2131 MicroTune MT2131 ATSC demodulator
nxt2k NxtWave Communications NXT2004 ATSC demodulator
zl10353 Zarlink ZL10353 (Intel CE623x) COFDM/DVB-T demodulator
The supported tuners are:
tvpll Generic PLL-based tuners
xc3028 XCeive XC3028 analog and digital tuner
xc5k Xceive XC5000 analog and digital tuner

Introduction
I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:
$ ls -ld /usr/bin /usr/bin/cat
drwxrwxr-x 3 root bin 8704 Sep 23 2004 /usr/bin

I have a file which looks roughly like this:
996 mmmmmmm

9964 fffffffffffff
and would like to sort it numerically on the first field. I tried:
sort -nr --key=1 ....
The output I get is:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I'm trying to install a PGX32 video card on my Sparc 10 Ultra running Solaris 10.
I've got the Oracle installation guide for it and I got as far as:

I don't have a CD-ROM by that name and a web search for that... (21 Replies)
Hey All,
Quick question...
I'm writing a short script to check if a continuous port is running on a server.
I'm using "ps -ef | grep -v grep | grep processName" and I was wondering if it was better/more reliable to just check the
return code from the command or if its better to pipe to... (12 Replies)
I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
Hi,
I am learning shell scripting for the first time. I use AT&T Korn Shell, Version AJM 93u+ 2012-08-01, compiled from source on NetBSD.
So far I have managed to set up what I think is a useful and pleasing shell prompt, which can be seen in the image attached to this post.
The prompt is... (2 Replies)
Hey gang, I have a list of times I need to sum up. This list can vary from a few to a few thousand entries. Now I had found a closed reference to adding time titled "add up time with xx:yy format in bash how?" In it, the example works great for that formatted list of times... This is the reply code...

Usually when I on the evening go to bed I take some interesting book with me. I read it for a while to get me down to sleep. Probably most people seek information from the Nett by googleing but I am so oldfashioned I prefer a real book ;)
But what a book. The one I found and ordered is BSD Unix®... (0 Replies)
