I have looked online, but find no answer. I believe a common DVD or Blu Ray disc contains 5 audio and 1 video tracks. I do not like HDMI, so I use the coax jacks to connect the audio signal to my receiver in my HT system and component cables to my TV for the video signals. I wonder how many audio tracks this coax cable can carry with 7.1 and the new Dolby Atmos receivers?

Hi,
In the pro world you get something called MADI (Multichannel Audio Digital Interface) aka AES10 (SPDIF/AES-EBU is in effect AES3) which uses a single coaxial cable per direction for distances up to 100 meters.
MADI can handle 28 Channels of 96khz/24Bit audio, higher sample rates can be used at reduced channel count (e.g. 14 Channels @ 192kHz, 7 Channels @ 384kHz....) and lower sample rates can increase channel count.

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to untolerable pain. Really, what more could we need?
The coax cable itself is capable of carrying the full bandwidth of lossless formats like Dolby TrueHD. However, the SPDiF protocol that is used to transports the data only has sufficient bandwidth for the lossy Dolby Digital 5.1 standard.
New formats like Dolby Atmos do not change the capabilities of the SPDIF protocol. Atmos is layered on top of the HD 7.1 format (some call it 7.1.4, for the four overhead channels).
Cerebrate!
In some sets of composite wires (red/white/yellow), the yellow (video) wire is a heavier gauge (I am guessing 16 or 14 gauge), and that is what I am using. I can ask at stores, but I doubt they would know either. I will probably have to call a manufacturer...
When you are looking at a red/white/yellow cable, that is composite video on the yellow and left/right audio on the white/red (normally). The video cable is shielded, so seems heavier.
If you insist on an analog connection, you should be using component video cables, where all three are identical coax conductors, to carry the three independent colors to your display.
But HDMI is so much more capable, and so much easier to connect, it is hard to understand why people use anything else these days for video.
But, whatever! Enjoy your system.
Cerebrate!
I use this for audio only. I do use component cables for video.
There are many problems with HDMI cables as I see it
1) if you use HDMI to the TV, you also get a un needed audio signal there (You want the receiver to do the decoding to get separate audio signals to each speaker)
2) the HDMI connection was designed poorly and comes out to easily
3) Some receivers are "pass trough" only, or worse yet, onlyfor the audio signal. You want the receiver to do the decoding for separate audio signals.
4) I do not like the trend of newer Blu Ray players have of only having only an HDMI jack...I like choices
5) People like to buy receivers or amps with HDMI jacks. Why? The more components a signal passes through, the worse it becomes.
You can send analog or digital signals through it and, depending on the design and construction it will do either, well or poorly.As for your damnation of HDMI, it is not entirely warranted.
Point 1: You do not necessarily get audio on it (if it is sent by a receiver that is doing the audio processing) but there's no harm if it is there.
Point 2: True but there are solutions to reinforce the connection. I use latching HDMI connectors.
Point 3: Only old and cheezy AVRs are that way. Anything bought in the past 5-6 years will do better unless it was bought in a pawn shop.
Point 4: Yes, it is better to have more choices but you have to pay for them.
Point 5: These days, the signals are all digital (except for LPs). So, keeping them digital as long as possible up to the point making sound (at the speaker) or picture (at the display), the better the outcome. Analog connections/processing encumber noise and distortion.

I get 94 Mbps throughput via my cable provider using coax.
Depends on how compressed they are. I suspect you will get only regular old DolbyDigital 5.1 with a coax cable.

Well there is a lot of data and I would prefer a standard where audio and video were separate. HDMI is for convenience as I see it.
