Panasonic DVD Video Recorder
If you are recording from a TV
and the DVD recorder’s output is hooked up to the same TV
Do Not adjust any settings on the DVD recorder
or bring up any menus
If you do not follow these cautions, the output from the TV will include those menus, thereby ruining your recording. Also, this can create a very nasty visual feedback loop that could harm the TV and/or DVD recorder.
Getting Started
Check the Connections
First, to verify that the DVD recorder is/will record(ing) successfully/properly, make sure that the RCA (Yellow, Red, and White plugs) OUTPUT connections are hooked up to a TV’s INPUT connections.
Second, ask yourself a simple but important question: I wish to record from …?
If you have a VHS tape, then the VCR would be appropriate
If you wish to record a TV program, a TV will be needed
etc
Hook the OUTPUT from the device you wish to record from (VCR, TV, etc.) into the INPUT on the DVD recorder. INPUT 2 is located on the front left of the DVD recorder, under a panel that flips down.
There are Two Types of DVDs
Now that the connections have been verified, insert a blank DVD into the recorder. There are two primary types of recordable DVDs:
DVD-R(W) is the standard type
and DVD-RAM (also available in rewritable)
The difference/benefit of the –RAM type is that you can watch (access) previously recorded pieces while recording at the same time! This allows you to perform your own instant replays of things, without having to stop the recording process.
Lights, Camera, and Action …
Now that you have inserted the blank media, you are ready to record.
Queue up the portion of the video that you wish to capture (fast forward or rewind as necessary if you are recording from tape)
Simply press Record on the DVD recorder remote, and press Play on the video source (if you source is a live broadcast, pressing Play is a moot point!)
As always, it is extremely beneficial to give yourself a bit of extraneous video at the beginning and end of the clip. These can be easily edited out later
But NOT, however, if you are using a non-rewritable disk
When the portion you wish to record has finished, simply press Stop on the DVD recorder remote to stop the record process.
What if you cannot “stand by” while recording? If you press Record more than once, you will “preset” a fixed recording time. This is sometimes called One Touch Recording, but is not the same as Timed Recording (see next section). The number of presses sets the time as follows:
Pressing the Record button 1 additional time will set the timer for 30 minutes
Pressing it 2 additional times will set it for 1 hour
Pressing 3 additional times will set it for 1 hour 30 minutes
Pressing 4 additional times will set it for 2 hours
Pressing 5 additional times equals 3 hours
Pressing 6 additional times equals 4 hours
Pressing 7 additional times will turn off the timer
To view the amount of time remaining, slide down the cover on the bottom of the DVD recorder remote (on the side with buttons; it’s just covering up the really advanced buttons). Pressing the Status button will display the remaining time until the recorder stops recording, if you have initiated the timer.
Timed Recording
Timed recordings are used most often when you want to capture a live broadcast such as your favorite TV show.
Press the Functions button, located to the lower left of the four arrow selection buttons on the remote
Select Timer Recording, which is the middle, left selection (press enter, the button in the center of the four arrow selection buttons to make a choice)
If you have no other timings set up, then the top spot will be available to input a time
If you have other timed recordings already set, arrow down to an empty spot and press enter.
In the screen that is then pulled up, enter the channel you wish to record from (arrowing up or down will allow you to select the Line In options, but why you would want a timed recording from them is beyond me.)
Once you have entered a channel, arrow right once to get to the date option.
Select the date you wish the recording to take place on; the default is today.
Using the up and down arrows will allow you to set the date to “every Saturday” or whichever day you choose, or to record every weekday, weekend, or weekday + Saturday. There are several options; arrow through them and pick which one is best for your needs
Arrow right when you have chosen a date.
The next box is the start time, that is when should the recording start.
I recommend starting approximately 5-10 minutes before the event you wish to capture, depending on the importance of the event. The reason for this is that you may disagree with the broadcast company as to the current time, so your show might start a minute or two before you think it should.
The default “on” time is the current time
Arrow right when you have entered the appropriate time
The next box is the time to stop time
For the previously mentioned reasons, I recommend selecting a time 5-10 minutes after the event you wish to capture
Arrow right when you have selected an appropriate time.
The final box is the quality you wish of your video capture. The higher the quality, the better the playback, but the more space it takes up on the DVD. Below is a chart illustrating the number of hours of video various DVDs can hold at the different qualities:
Mode/Disc type
DVD-RAM
DVD-R(4.7 GB)
Single-sided(4.7 GB)
Double-sided(9.4 GB)
XP (High Quality)
1
2
1
SP (Normal)
2
4
2
LP (Long Play)
4
8
4
EP (Extra Long Play)
6
12
6
FR (Flexible Recording Option)
There is an additional option not mentioned in this list, FR. If this option is selected, the recording process will automatically adjust the picture quality to give you the best possible quality for the remaining space on the DVD
SP (standard play) should be good enough for any and everything, hence the reason for it being the default
Press enter when you have chosen the quality. To delete a recording time, arrow to the selection you wish to delete, and press enter to open it. Press the cancel button located to the left of the zero button. This will erase that time. Press enter to exit the now-deleted time.
Exploring the Contents of the DVD
Once you have recorded something (or while you are recording something, if you are using a DVD-RAM) you may navigate the contents of the DVD using the Direct Navigator button, located to the upper left of the arrow selection buttons. In the menu that this button brings up will be a list of the recorded programs, with a red circle next to the one that is currently recording.
To edit any of these programs
Arrow up or down to highlight the desired program
Arrow right to select the program
NOTE: you cannot edit a program while it is being recorded
You now have six options
Erase program, which does just what it says
Enter title, which pulls up an onscreen keyboard that allows you to name a previously recorded program
Properties, which will tell you
the number of the program
the date/time it was recorded
the length of the clip
and the channel it was recorded from
Protection, which allows you to protect the program from being deleted, or to remove that protection
Shorten segment, which will remove a selected chunk from the clip
Divide program, which will divide your program at the desired point
I recommend using Divide program instead of Shorten segment if you wish to remove a chunk starting at the beginning
Shorten segment requires you to press the enter button to select the starting and stopping frame, while Divide program requires only that you pick the point to separate the two portions.
If you use the Direct Navigator menu, and wish to begin recording again, the Direct navigator menu must be closed before the DVD recorder will allow you to record anything. If you are recording something using a DVD-RAM, and press the Direct Navigator button, it will begin previewing your previously recorded programs while still recording whatever it is you are recording. You can even preview the program you are recording while you record it, with a thirty second delay between record time and preview time. To exit the preview, press the stop button once. If you press it twice, you’ll stop the recording process.

ASSIGNMENT No:2-PACKAGE TYPES

The first Pentium III core, Katmai, was not much different from its predecessor, Pentium II Deschutes core. Like the Deschutes-based Pentium II processors, the Katmai-based Pentium III CPUs had 512 KB back-side L2 cache running at half of the core frequency. These Pentium 3 CPUs were packaged in SECC 2 package, plugged into Slot 1 connector, used the same 0.25 micron manufacturing technology, and even had the same core voltage as Pentium IIs. As a result new Pentium 3 processors had good compatibility with old Pentium II motherboards.

The major feature of the Katmai core was SSE instruction set - 70 new SIMD instructions. These instructions were originally called KNI, or Katmai New Instructions. The SSE instructions could significantly improve performance of multimedia and graphics applications, but only if the applications were recompiled to take advantage of new instructions.

Another new "feature" of Pentium III processor was Processor Serial Number, or PSN. The PSN was unique for each Pentium III CPU, and it could be used to uniquely identify the computer. Due to privacy concerns this feature was by default disabled on many motherboards.

All CPUs with Katmai core were released during short period of time. First Pentium IIIs, running at speeds 450 and 500 MHz, were introduced in February of 1999. Just in 7 months, in September 1999, Intel released the latest and the fastest Katmai 600 MHz CPU with 133 MHz FSB.

To compare different versions of Pentium III CPUs please see Intel desktop Pentium III CPU chart.

Pentium III family

At a glance


Introduction:
1999
Technology:
0.25 micron
Frequency (MHz):
450 - 600
L2 cache size (KB):
512



Intel Pentium III 400 - DC1EC501A400 KATMAI
400 MHz
512 KB L2 cache
Single Edge Contact cartridge (slot 1)

This early engineering sample of Pentium III processor is interesting for a few different reasons:


It was manufactured about 8 months before the launch of Pentium III family.

The processor is clocked at 400 MHz, and production version of Pentium 3 400 MHz was never officially released.

The processor has unusual part number. It's also curious that the "Katmai" core name is printed on the CPU next to the part number.

Intel Pentium III 400 - 80525PZ400512

400 MHz (133 MHz bus)
512 KB L2 cache
Single Edge Contact cartridge 2 (slot 1)

Produced later than the DC1EC501A400 CPU this engineering sample has very significant feature - 133 MHz front side. Increasing front side bus speed from 100 MHz to 133 MHz allowed to increase processor performance by 5% - 10% on average.

It's worth to note that this processor was manufactured almost 11 months before the release of first Katmai processors with 133 MHz bus speed


FC-PGA Package Type

















The FC-PGA package is short for flip chip pin grid array, which have pins that are inserted into a socket. These chips are turned upside down so that the die or the part of the processor that makes up the computer chip is exposed on the top of the processor. By having the die exposed allows the thermal solution can be applied directly to the die, which allows for more efficient cooling of the chip. To enhance the performance of the package by decoupling the power and ground signals, FC-PGA processors have discrete capacitors and resistors on the bottom of the processor, in the capacitor placement area (center of processor). The pins on the bottom of the chip are staggered. In addition, the pins are arranged in a way that the processor can only be inserted one way into the socket. The FC-PGA package is used in Pentium® III and Intel® Celeron® processor.



Cpu Sockets

Socket 939

Socket 939 is a PGA socket designed for desktop K8 microprocessors. The socket is primarily used with Athlon 64, Athlon 64 X2 and Athlon FX microprocessors. AMD also manufactured uni-processor single and dual-core Opteron processors for the socket 939, although these processors were just re-branded Athlon 64/64 X2 CPUs with larger level 2 cache. In addition to that small number (compared to the total number of processors for this socket) of socket 939 Sempron processors was produced for this socket.

Picture of Socket 939

The socket can be used with processors with internal frequencies from 1.8 GHz to 3 GHz, or with rated frequencies 3000+ - 4800+. All processors working in this socket have one HyperTransport link, dual-channel DDR memory controller, and support DDR-200 - DDR-400 unbuffered memory DIMMs.

Supported processors

Sempron / Sempron 64 (1.8 GHz - 2 GHz, or 3000+ - 3500+)
Athlon 64 (1.8 GHz - 2.4 GHz, or 3000+ - 4000+)
Athlon 64 X2 (2 GHz - 2.4 GHz, or 3800+ - 4800+)
Athlon 64 FX (FX-53 - FX-60)
Opteron (1.8 GHz - 3 GHz, or model 144 - model 156)
Dual-Core Opteron (1.8 GHz - 2.6 GHz, or model 165 - model 185)

There are no Intel or VIA processors compatible with this socket.

NOTE: Not all processors may be supported by all motherboards. Please see "Upgrading socket 939 motherboards" section below on how to determine what microprocessors can be supported by your motherboard.




Socket 7 (Socket7)

Socket 7 was introduced by Intel for it's Pentium 133 - 200 MHz processors and for Pentium MMX processor family. The major feature of the new socket was support for dual plane voltage - the socket could supply different voltages to processor core and I/O logic. At the same time, the socket 7 was backward compatible with socket 5, and it was possible to run older (single voltage) processors in socket 7 motherboards. For their next generation of processors Intel chose different socket type - slot 1, and completely abandoned socket 7. Luckily, Intel competitors continued to support socket 7 architecture, and they even enhanced it by creating a "Super socket 7" specification by adding support for 100 MHz bus frequency, backside L2 cache and frontside L3 cache.

Picture of Socket 7

Socket 7 has 321 pin holes arranged as 37 x 37 pin matrix. The socket has the same size as the Socket 5, but the socket 5 has only 320 pin holes. The extra pin on socket 7 processors is not electrically connected and it's main purpose is to prevent socket 7 processors to be inserted into socket 5 motherboards.

Supported processors

AMD K5 (75 MHz - 200 MHz)
AMD K6 (166 MHz - 300 MHz)
AMD K6-2 (200 MHz - 570 MHz, often requires 100 MHz bus support)
AMD K6-III (333 MHz - 550 MHz, often requires 100 MHz bus support)
Cyrix 6x86, 6x86L and 6x86MX (90 MHz - 266 MHz)
Cyrix MII (233 MHz - 433 MHz)
IBM 6x86, 6x86L and 6x86MX (90 MHz - 300 MHz)
IDT Winchip C6 (180 MHz - 240 MHz)
IDT Winchip 2 (200 MHz - 240 MHz)
Intel Pentium (non-MMX) (75 MHz - 200 MHz)
Intel Pentium MMX (166 MHz - 233 MHz)
Rise Technology MP6 (150 MHz - 366 MHz)
ST 6x86 (90 MHz - 166 MHz)

Compatible package types

296-pin staggered Plastic Pin Grid Array (PPGA)
296-pin staggered Ceramic Pin Grid Array (CPGA or SPGA)
296-pin Flip-Chip staggered Ceramic Pin Grid Array
321-pin ceramic Ping Grid Array (CPGA)

Upgrading socket 7 motherboards

Although many socket7 microprocessors will fit into your motherboard, not all of them may be supported by the board. To determine the fastest processor for your motherboard you'll need to:

  • Determine manufacturer and model of your motherboard,
  • Search on manufacturer's website for the motherboard model.
To determine upgrade options for brand name computers (like Dell or HP) try to search for computer model on computer manufacturer website.

For upgrade information for ABIT, ASrock, ASUS, DFI, ECS, Gigabyte Technology, Jetway, MSI, PC Chips and Shuttle motherboards please check CPU-Upgrade motherboard database.

Motherboard Form Factors
The form factor of a motherboard determines the specifications for its general shape and size. It also specifies what type of case and power supply will be supported, the placement of mounting holes, and the physical layout and organization of the board. Form factor is especially important if you build your own computer systems and need to ensure that you purchase the correct case and components.



The Succession of Motherboard Form Factors
AT & Baby AT

Prior to 1997, IBM computers used large motherboards. After that, however, the size of the motherboard was reduced and boards using the AT (Advanced Technology) form factor was released. The AT form factor is found in older computers (386 class or earlier). Some of the problems with this form factor mainly arose from the physical size of the board, which is 12" wide, often causing the board to overlap with space required for the drive bays.
Following the AT form factor, the Baby AT form factor was introduced. With the Baby AT form factor the width of the motherboard was decreased from 12" to 8.5", limiting problems associated with overlapping on the drive bays' turf. Baby AT became popular and was designed for peripheral devices — such as the keyboard, mouse, and video — to be contained on circuit boards that were connected by way of expansion slots on the motherboard.
Baby AT was not without problems however. Computer memory itself advanced, and the Baby AT form factor had memory sockets at the front of the motherboard. As processors became larger, the Baby AT form factor did not allow for space to use a combination of processor, heatsink, and fan. The ATX form factor was then designed to overcome these issues.


ATX
With the need for a more integrated form factor which defined standard locations for the keyboard, mouse, I/O, and video connectors, in the mid 1990's the ATX form factor was introduced. The ATX form factor brought about many chances in the computer. Since the expansion slots were put onto separate riser cards that plugged into the motherboard, the overall size of the computer and its case was reduced. The ATX form factor specified changes to the motherboard, along with the case and power supply. Some of the design specification improvements of the ATX form factor included a single 20-pin connector for the power supply, a power supply to blow air into the case instead of out for better air flow, less overlap between the motherboard and drive bays, and integrated I/O Port connectors soldered directly onto the motherboard. The ATX form factor was an overall better design for upgrading.

micro-ATX

MicroATX followed the ATX form factor and offered the same benefits but improved the overall system design costs through a reduction in the physical size of the motherboard. This was done by reducing the number of I/O slots supported on the board. The microATX form factor also provided more I/O space at the rear and reduced emissions from using integrated I/O connectors.



LPX
White ATX is the most well-known and used form factor, there is also a non-standard proprietary form factor which falls under the name of LPX, and Mini-LPX. The LPX form factor is found in low-profile cases (desktop model as opposed to a tower or mini-tower) with a riser card arrangement for expansion cards where expansion boards run parallel to the motherboard. While this allows for smaller cases it also limits the number of expansion slots available. Most LPX motherboards have sound and video integrated onto the motherboard. While this can make for a low-cost and space saving product they are generally difficult to repair due to a lack of space and overall non-standardization. The LPX form factor is not suited to upgrading and offer poor cooling.
NLX
Boards based on the NLX form factor hit the market in the late 1990's. This "updated LPX" form factor offered support for larger memory modules, tower cases, AGP video support and reduced cable length. In addition, motherboards are easier to remove. The NLX form factor, unlike LPX is an actual standard which means there is more component options for upgrading and repair.
Many systems that were formerly designed to fit the LPX form factor are moving over to NLX. The NLX form factor is well-suited to mass-market retail PCs.

BTX
The BTX, or Balanced Technology Extended form factor, unlike its predecessors is not an evolution of a previous form factor but a total break away from the popular and dominating ATX form factor. BTX was developed to take advantage of technologies such as Serial ATA, USB 2.0, and PCI Express. Changes to the layout with the BTX form factor include better component placement for back panel I/O controllers and it is smaller than microATX systems. The BTX form factor provides the industry push to tower size systems with an increased number of system slots.
One of the most talked about features of the BTX form factor is that it uses in-line airflow. In the BTX form factor the memory slots and expansion slots have switched places, allowing the main components (processor, chipset, and graphics controller) to use the same airflow which reduces the number of fans needed in the system; thereby reducing noise. To assist in noise reduction BTX system level acoustics have been improved by a reduced air turbulence within the in-line airflow system.
Initially there will be three motherboards offered in BTX form factor. The first, picoBTX will offer four mounting holes and one expansion slot, while microBTX will hold seven mounting holes and four expansion slots, and lastly, regularBTX will offer 10 mounting holes and seven expansion slots. The new BTX form factor design is incompatible with ATX, with the exception of being able to use an ATX power supply with BTX boards.
Today the industry accepts the ATX form factor as the standard, however legacy AT systems are still widely in use. Since the BTX form factor design is incompatible with ATX, only time will tell if it will overtake ATX as the industry standard.
