circuit schematic help

[punksatony]

Hello, I was just wondering if you guys could help me decipher this schematic?  I'm pretty bad with electricity and the physics of energy and all that, but I know some basics.  Basically I need help with the following diagram with parts circled in grey:

1. the inputs to the NAND gates... is this just one wire split into two?
2. what do these symbols mean?  Is this a ground symbol?  and if so, can I connect all "grounds" to the same grounded spot?
3. Not sure what these symbols mean either (the two same-length, vertical lines with one bold... around the NAND gates)
4.  the VCC's and VEE's - I understand these are the power (+/- 5v in this case), but should I just connect a power input wire wherever there's a VCC and the output wire (negative) wherever there's a VEE?
5.  Not sure what these symbols are either?  they look like capacitors without the straight line (only the half circle)

Also for the op-amps, there's only one output coming from the point of the triangle, but what are the VCC's and VEE's doing there? (How/where do I connect these if there are only three places to connect (+ terminal, - terminal, and "output" terminal (coming out from triangle point)?

Lastly, in terms of wiring... could I connect wires exactly as they are in the schematic (obviously only making connections where they are implied)?  Like near the top right, after the PNP but before the NPN, after the 1k resistor where the wire from the 1.8k resistor connects - in terms of wires could that wire coming from the 1k be sheathed and just connected to the NPN, but before the NPN also have a thin segment of that same wire (from the 1k) unsheathed and have the wire coming from the 1.8k connected at that unsheathed junction?  Is that how all this works?

Thanks for all your time and help.

I just noticed some lines were left out of the diagram up there (maybe if downloaded they show up, but just in the actual post they're missing). 

1. The line coming out of the non-arrowed line from the NPN should connect to the line that is connected to the + terminal of the top op-amp.
2. All the VCC's and VEE's around the op-amp's should connect directly (either up or down) to the op-amp they surround (the line goes from either VCC or VEE to a side of the op-amp's triangle, not one of the =/- terminals on the left nor the points (outputs) on the right.  Lastly those lines that go from the VCCs/VEEs to the op-amps also are connected to those downward-pointing triangles with the capacitors before the triangles (the two lines intersect before the capacitors)

Thanks again for the help

vcc and vee are your positive and negative supply lines.

The down arrows are reference to ground and are usually a mid point between the vcc and vee.
The grounds should all be connected together and should have a common point at which the ground is connected to the circuit.

The NAND gates with both inputs connected: This is a way to make a NAND gate into an Inverter.

The arrow that is circling the signal wire is a reference that you want to shield this wire.

The symbol with the half circles are capacitors. The 0.1 marking is the value. This is telling you to connect the capacitor between the vcc and ground and to connect a capacitor between vee and ground.

hope this is helpful.

Cool man thanks, that's a bunch of help and confirmed my suspicions for most things.  I'm still a little shaky on a couple of issues though:

#5's circled (the half circles near the RGB & YPrPb's) - are those the "shielding" you're talking about?  Does that mean shield the respective input/output (R/G/B or Y/Pr/Pb) or shield the ground wire coming off those?

#3's (w/ 0.03 and 0.002 markings) are these non-polarized capacitors as opposed to the ones where one line is a half circle with the 0.1 markings like you said (polarized capacitors?)

Also, what kind of wire should I use for all of these connections?  The thinner the better preferably as I'll be putting it all in a project box.
-Does the wattage of resistor I use matter (1/8, 1/4, 1/2, etc) or does only the ohm rating matter?
-How do I adjust the pulse-width at those two points that are arrowed (to 190uS high pulse-width and 2.5uS low pulse-width, respectively)?
-The resistors with the arrows through them, are those potentionmeters or rheostats, or are those the same thing?
-numbers like 74HC0D, 2N3906, 2N2222, EL2D45... I assume those are calling for specific part numbers, but are those the exact parts I need or more like just suggestions?
-"The schematic does not show the power supply, but basically a split supply capable of about 100mA should do fine. In my case, I use a 'wall' transformer which gave me 9VAC and generated split supplies using 78L05 and 79L05 regulators" that's from the site the schematic's from (http://www.keohi.com/keohihdtv/interfaces/diytranscoder.html)... what does that mean?  What's the easiest way to pull that off, whatever it does mean?

Thanks again.

There is no reason to shield a ground wire. Just shield the signal wires.
The cpaacitors are non polarized. You will see them with a half circle or two straight lines. The polarized caps will have a plus symbol on the positive side of the symbol. Very small bypass caps will not be polarized.
You cannot use a 9 volt supply to power a bipolar 5 volt.  Bipolar 5 volt means +5 volts and -5 volts. This is a range of 10 volts.
You will use shielded cable for most of these connections. This is like coax cable used for TV connections to cable.
1/4 watt are probably the most readily available resistors. This will be fine and will give you plenty of overhead.
