AV Cables
Microsoft has released a handful of Audio Video Cables for the Xbox, which they refer to internally as AV Packs. They are connected to the port labelled "Audio Video Input/Output" on the backside of the console.

Pinout
The following table gives the pinout in the way it is arranged on the XBOX AVIP cables, or AV Packs. The other end is reversed and on the console.
| Description | Audio Right | Audio Right GND | SPDIF Digital Audio | V-Sync (VGA Mode) | Mode GND | Mode GND | Mode GND | GND | Variable | 9 GND | Variable | 11 GND |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Pin | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
| Pin | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 |
| Description | Vcc | Audio Left | Audio Left GND | H Sync (VGA Mode) | Mode Select 1 | Mode Select 2 | Mode Select 3 | (+12V) | 22 GND | Variable | 24 GND | Variable |
Supported signals / AV cables
Below is a table which lists all known officially AV cables released by Microsoft and their respective signal. The constants used in the av-prefixed Kernel-functions are also listed.
| Pin 19 | Pin 18 | Pin 17 | SMC Constant | Region | Official Microsoft product name | Signal | Pin 24 | Pin 22 | Pin 11 | Pin 9 | Kernel av-Constant |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 0 | 0 | 0 | 0 | PAL | Advanced SCART Cable | SCART (15 kHz RGB) Stereo | V | R | G | B | AV_PACK_SCART = 3 |
| 0 | 0 | 1 | 1 | NTSC | High Definition AV Pack | Component SPDIF | - | Pr | Y | Pb | AV_PACK_HDTV = 4 |
| 0 | 1 | 0 | 2 | - | Not officially available / supported | VGA (31 kHz RGB) Stereo | - | R | G | B | AV_PACK_VGA = 5 |
| 0 | 1 | 1 | 3 | NTSC / PAL | RF Adapter | RF Mono | V | C | Y | - | AV_PACK_RFU = 2 |
| 1 | 0 | 0 | 4 | NTSC | Advanced AV Pack | S-Video Stereo | V | C | Y | - | AV_PACK_SVIDEO = 6 |
| 1 | 0 | 1 | 5 | - | Not officially available / supported | Unknown Mono | V | C | Y | - | AV_PACK_NONE = 0 |
| 1 | 1 | 0 | 6 | NTSC / PAL | Standard AV Cable | Composite Stereo | V | C | Y | - | AV_PACK_STANDARD = 1 |
| 1 | 1 | 1 | 7 | - | No cable connected | - | - | - | - | - | AV_PACK_NONE = 0 |
A signal value of 0 means connection to ground (Pins 7, 6, 5), whereas a value of 1 means an open-connection[citation needed]
The region only identifies which territory the cable was originally available / intended for. The kernel still might support other video-standards (NTSC / PAL / SECAM) using the same cable.
