Does that imply you have a Hauppauge (PCI) tuner?
I will set it up. However, my wife has the most interest in
programming shows, so a friendly interface is required!
It sounds like sort of an interesting project. Thus, far I have avoided
any sort of file sharing over our (local) network, but there are some
interesting possibilities here.
Thank you for your encouragement! : )
I have two hauppauge tuners. The first one stopped working properly on
one input and was replaced with another with more features. The first
one is PCI, while the second is PCIe. They are not compatible!
You may find the biggest hassle in all this is getting program guide
data for scheduling. Not all digital TV stations send out their guide
data properly or very far in advance.
I haven't checked the situation recently, but I think I got a good deal
on my PCIe external HDD because of the lack of popularity of PCIe at the
time. I think it's much faster than USB 2.0 as well, more akin to USB
3.0, but don't quote me on that. I can just say that it does what it's
supposed to do quite well. What are you sentiments about PCIe?
PCIe's just the next generation of expansion slot. I usually prefer
internal cards to external devices because it makes it harder to lose
the device or for it to become distached.
For TV tuner use, the tuner matters more than the interface. If the
tuner is doing the hard work itself, you only need to send the finished
data to the system.
A PCIe external hard drive doesn't make sense. Are you thinking of
eSATA? (Firewire and USB are common interfaces as well.)
Yes, it is surely eSATA. Sorry about the confusion. Are eSATA devices
very popular now with the presence of USB 3.0? My motherboard (made by
GIGA-BYTE) has USB 3.0 too, but I haven't used it. Strangely, its USB
3.0 shares a bus with its graphics card, so my graphics speed is
supposed to be cut in half if I use USB 3.0. Not having used it, I don't
know whether that means all the time, or only when the USB port is
"working". I would guess the former.
I'm not sure about eSATA devices and USB 3.0. I really haven't had a
need for external drives since I set up a NAS box. The NAS box has
eSATA ports, but I've never used them.
eSATA might turn out to be kinda like Firewire. The standard and
interface has been out for years, but not a lot of devices use it.
For non-consumer usage, eSATA is preferred. Will run at full 6Gbit/sec
with SATA III ports. (SATA I - 1.5Gbits/sec, SATA II = 3.0Gbits/sec).
As a consumer, I'd prefer eSATA because the consumer SATA <-> USB
interface adapters are quite often junk (the drive itself is still
SATA even when connected via USB).
USB 3.0 is spec'ed to do 5.0Gbits/sec, but there've been reports of
cheap USB 3 hardware reverting to 0.5Gbits/sec (particularly when using
cheap cables, but often for other reasons).
Not a bus, per se, but rather bandwidth. The port upstream (to/from memory)
root complex handling the USB 3 and Graphics has bandwidth which is
less than the combined required bandwidth of the super-speed (5.0Gb/s)
USB and the Graphics. Common when using the DMI bus from the processor
to a chipset providing legacy devices (USB, integrated graphics, SATA,
et. al.) such as the ICH (Nahalem) or PCH (Sandybridge).
The PCI local bus is a standard parallel bus used to connected peripheral
adapter cards to the processor complex, via one or more PCI bridges. The
PCI bus is pretty much obsolete at this point, having been replaced in
most systems by the serial, point-to-point PCI Express bus (aka PCIe).
A PCIe root complex provides one or more SERDES lanes (usually in groups of
four, 8 or 16) which use differential signalling to support fast serial
transfers on each lane; the lanes can be grouped such that 1, 4, 8 or 16
lanes are connected to a PCIe endpoint (e.g. SATA adapter, NIC, Infiniband,
Graphics card). The number of lanes (and PCIe generation) govern the bandwidth
available between the adapter card and the memory subsystem.
Most new systems no longer have PCI peripheral slots (but may, internally within
the chipset, use PCI-PCI bridges for legacy peripherals); but rather include
one or more X1, X4, X8 or X16 PCIexpress slots.
I suspect that your "PCIe external HDD" is really eSATA (external SATA) connected
to a SATA controller which interfaces via a PCIe Root Complex to the
subsystem. There is a new standard coming for SSD (solid-state disk) access via
PCIe (Called NVM Express/NVMe), but it won't handle ATA drives (it's designed for
plugin PCIe cards with large quantities of NAND/NOR flash chips on board).
I can see you really know your stuff! One just can't have enough
communication protocals! ; )
Seeing the tiny little 32-GB micro-SD chips on sale for $30 or so
(which plug into a phone, for instance), one has to accept that some
things have changed! -- LOL. ; )
It wasn't a Seagate ST225 by any chance, was it? It was a really common
drive that fit your description.
I've got an IBM XT with a full-height hard drive. I don't remember the
capacity, but it wasn't much. Somewhere less than 20MB, I believe. (I've
also got a couple of the ST225s.)
Last year, we used punch cards in a chemistry class... Ok, we wrote on
them like they were note cards because the instructors claimed they were
easier to handle than 1/2 sheets of paper for the short quizzes they gave
My first desktop was an XT clone with a 30 MB hard drive and an amber
Had an internal Fax card and a 56K modem.
Ran my business well into the mid '90's before the HD crapped out.
So the little 32GB Micro-SD card holds 50 x 32 = 1600 times as much!!!
I was thinking that multiple was 160, at first, and it's how many times
smaller? Wikipedia says it's 15mm by 11 mm, or about 5/8" x 1/2" to
non-metricians. Yep, 32 GB in 5/16" of a square inch. More than 32
billions bytes, which is 8x32%6 billion bits! More than enough to
count even... Even 256 would be too many for me to count, unless I put
them in stacks of 10 = F +1 (=2^4 -1).
When I started in the biz, we had the large 5MB (5ms latency) head-per-track disk
drive (the size of a washing machine - the heads were pneumatically
loaded, so each disk unit had a built-in air compressor and storage
tank). We also had a bunch of 100-200MB removable drives. When we got
our first memorex 3680 (1GB), it took a fork lift to bring it into the
computer room. The 3682's were even larger, but fast (for the day).
Today, you've got helium-filled multiplatter drives coming this year
from WD, and in a couple of years, heat-activated recording technology
is poised to double or triple areal density, and there are additional
technologies in the pipeline; not to mention the terabyte SSD's by
Violin, FusionIO, Huawei, LSI, et alia. You've also got a couple of
flash replacements in the pipeline with Phase-Change Recording (PCR) and
Magento-resistive memory (MRAM).
How about a USB 2.0 Device: Hauppauges "WinTV HVR-950 hybrid TV stick"
(NTSC/ATSC HD TV reciever). This is handy since my wife already has one
(I've got her looking for the software)! It being small, I expect it is
leaving lots of processing to the host CPU which otherwise might be done
by a tuner on a PCI card. True? It reminds me of the "hardware (phone)
modem versus virtual modem" debate that the Linux people carried on for
I downloaded the software and drivers to support the TV-stick for
Windows Media Center from Hauppauges support pages. Then I unplugged the
rabbit ears from my tv and hooked them up to my usb device. And hey it
works, including 2 weeks of TV-guide info!
A little file sharing, and we'll practically have a DVR!
I need more rabbit ears! I think this "system" needs ot be on my
wife's computer. : )
It looks like it uses a software-based encoder. If it works for you,
then no problem. You should be able to see how hard your CPU has to
work in Task Manager.
Hardware modems are still best. ;-)
Following that point of view cost me several hundred dollars over the
years at $79 a crack. A crack of lightning that is. I've still got my
last one; I would be willing to let you have it for $39.99. Do they
still sell them? : ) Maybe it's a "collectable"? : )
They do still sell them... priced around the $50-70 mark. I decided a
software modem would be good enough, especially considering the dual-core
nature of the machine I put it in. (Plus, it was free.)
Did you have a surge supressor on your line?
