Combined with the MSB in Register 0x8E these bits
indicate the last active video pixel in the display. All
pixels past this comprise a right vertical bar. If the
2-byte value is greater than the number of pixels in the
display, there is no vertical bar.

These bits identify the audio coding so that the
receiver may process audio properly.

These bits specify how many audio channels are being
sent—2 channels to 8 channels.

For compressed audio only when this value is
multiplied by 8 kHz represents the maximum bit rate.
A value of 0x08 in this field would yield a maximum
bit rate of (8 kHz × 8 kHz = 64 kHz).
7-0
These bits define the mapping (suggested placement)
of speakers.
