23. Channel Tuning

(Command:

m a)

To tune

channel

to

following

physical/major/minor

number.

Digital

channels

have a Physical,

Major,

and

Minor

channel

number.

The Physical

number

is the

actual

digital

channet

number,

the

Major

is the number

that

the channel

should

be mapped

to, and the

Minor

is

the sub-channel.

Since the ATSC tuner automatically

maps the

channel to the

Major number,

the

Physical

number

is not required

when

sending

a command.

Data 00: Physical Channel

Number

NTSC air: 02-45,

NTSC cable: 01, 0E-7D

ATSC air: 01-45,

ATSC cable: 01-87

Data 01 & 02: Major Channel Number

Data 01 : High byte

Data 02: Low

byte

Two

bytes

are available

for the

Major

and

Minor,

normally

only the second

byte is used.

Data 03 & 04: Minor Channel

Number

Not needed

for NTSC.

The table

above

lists

the

binary

code

which

must

be

converted

to

Hexadecimal

before

sending.

For

example:

The binary

code to tune

the sub source

to an NTSC

cable

channel

is "1000

0001 ", which

translates

to

"81 " in Hex.

*

7th

bit : For which

source

do you want

to

change

the channel.

*

6th

bit:

Use a two

part or one

part channel.

Most

cases

just

use

0 since

it's

ignored

when

using

NTSC.

*

5th

bit:

Use

0 with

NTSC

since

it can

only

use

the

physical

channet

number.

Normally

use

1 for

ATSC

since most

times

it doesn't

matter

what

the

physical

number

is.

* 4th bit: Set to 0.

* 3-0 bits: Choose

signal type.

* Tune Command

Examples:

1. Tune to the analog (NTSC) cable channel 35.

Data 00 = Physical of 35 = 23

Data 01 & 02 = No Major = 00 00

Data 03 & 04 = No Minor

= 00 00

Data 05 = 0000 0001 in binary = 01

Total = ma 00 23 00 00 00 00 01

2. Tune to the digital

(ATSC) local channel 30-3.

Data 00 = Don't

know

Physical = 00

Data 01 & 02 = Major

is 30 = 00 1E

Data 03 & 04 = Minor

is 3 = 00 03

Data 05 = 0010 0010 in binary = 22

Totat = ma 00 00 00 1E 00 03 22
