CD

changers

that

may

be

connected

as

a

media

source

to

the

media

manage

ment

system

10.

As

another

example,

a

media

unit

record

for

a

song

may

denote

that

the

song

is

located

Other

examples

of

the

date

are

also

possible.

The

media

type

de?nes

the

format

used

to

encode

a

media

unit.

Various

media

types

are

available

for

encoding

audio.

For

example,

a

media

type

may

include

the

Motion

Picture

Experts

Groupiaudio

layer

3

(MP3)

format,

a

CD

format,

a

SACD

format,

a

DVD

format(e.g.,

DVD-audio

or

DVD

movie),

a

Wavefonn

audio

(WAV)

format,

pulse

code

modu

lation

(PCM)

format,

free

lossless

audio

code

(FLAC)

format,

or

an

advance

audio

coding

(AAC)

format.

The

media

type

may

also

de?ne

Whether

the

media

unit

is

encoded

as

(i)

encrypted

or

unencrypted

media,

or

(ii)

compressed

or

uncompressed

media.

Other

examples

of

formats

for

digitally

encoding

audio

are

also

possible.

Further,

a

media

type

format

may

have

a

variety

of

encoding

characteristics.

For

example,

an

audio

recording

may

be

encoded

as

an

MP3

?le

in

mono

format

having

a

data

rate

of

96K

bits

per

second

(bps),

or

as

an

MP3

?le

in

stereo

format

having

a data

rate

of

96K

bps,

or

as

an

MP3

?le

in

stereo

format

having

a data

rate

of

192K

bps.

As

another

example,

the

AAC

format

could

be

encoded

using

a variable

bit

rate

or

a

constant

bit

rate

and

With

a

different

amount

of

audio

channels,

(eg

1

channel,

2

channels,

etc.).

Other

examples

of encoding

characteristics

of

the

MP3

format, the

AAC

format,

or

other

media

type

are

also

possible.

The

media

management

system 10

may

display

selected

information

about

the

media

from

the

media

unit

records

stored

in

the

media

database

19

on

a

display

32.

The

media

management

system 10

may

also

alloW

the

user

to

con?gure

and

select

media

to

play using

a

keyboard

34,

an

IR

remote

control

30

or

another

suitable

input

device.

The

media

management

system

10

may

include

a

user

interface

16

that

processes

user

input

and

output

via the

display

32

and

the

keyboard 34

and

provides

con?guration

and

execution

pro

cesses

to

alloW

the

user

to

manage

and

play

the

media

obtained

from

the

media

sources.

As

an

example,

the

display

32

may

comprise

a

touch-screen

that

alloWs

a

user

to

(i)

con?gure

and

select

media,

and

(ii)

select

play

modes,

by

touching

the

touch-screen

While

a

con?guration

and

selec

tion

screen

is

shoWn

on

the

display

32.

In a

preferred

embodiment,

the

user

interface

16

may

be

coupled

to

a

con?guration

process

17

that

alloWs

the

user

to

con?gure

the

media

38

to

dance

With

requirements

speci?ed

in

a

play

mode.

The

con?guration

process

17

may

display

screens

to

query

the

user

prompting

the

user

to

enter

information

about

play

modes

for

the

particular

media

types

available.

For

example,

the

query

may

be

displayed

on

a

display

terminal.

For

instance,

a

querying

function

may

include

querying

a

user

to

select

a

play

mode

of

a

plurality

of

play

modes

to

correspond

With

one

of

a

plurality

of

characteris

tics

identi?ed

in

a

media

unit

record,

continuing

to

query

the

user

to

select

play

modes

until

each of

the

plurality

of

characteristics

corresponds

With

one

of

the

plurality

of

play

modes,

and

storing

the

selected

play

modes

corresponding

to

the

plurality

of

characteristics

in

the

play

mode

record.

As

another

example,

the

querying

function

may

include

query

ing

a

user

to

select

one

of

a

plurality

of

receiver

connections

corresponding

to

one

of

a

plurality

of

media

types,

and

then

continuing

to

query

the

user

to

select

the

receiver

connec

tions

until

each

media

type

of

the

plurality

of

media

types

corresponds

to

a

selected

receiver

connection.

As

an

example,

the

user

may

specify

that

a

song

in

an

MP3

format

Will

be

played

on

a

receiver

via a

2-channel

analog

connection.

In

this

regard,

for

2-channel

analog,

the

media

management

system

10

processes

the

MP3

song

by

extracting

the

left

and

right

channel

analog

signals

of

the

MP3

song

and

then

sends

the

left

and

right

analog

signals

55

to

a

corresponding

2-channel

analog

connection

at

the

media

receiver

38.

The

media

receiver

38

may

process

the

left

and

right

channel

signals

55

by

amplifying

the

signals

before

outputting

the

signals

to

a

left

speaker

and

a

right

speaker

respectively.

As

another

example,

the

MP3

song

may

also

be

commu

nicated

digitally

(in

MP3

or

other

digital

format)

to

another

digital

player.

In

this

regard,

the

user

may

specify

a

receiver

connection

that

sends

a

digital

signal

53

from

the

digital

connection

52

to

a

corresponding

digital

connection

at

the

media

receiver

38.

As

yet

another

example,

the

user

may

specify a

receiver

connection

that

sends

6-channel

audio

signals

57

from

the

6-channel

audio

connection

56

to

a

corresponding

6-channel

audio

connection

at

the

media

receiver

38.

The

2-channel

analog

receiver

connection

is

only

one

of

many

media

receiver

connections

that

may

be

speci?ed

for

a

given

media

type.

Other

examples

of

media

receiver

connections

include:

(i)

5.1

analog

connections,

and

(ii)

digital

connections,

such

as

a

2-channel

digital

connection,

a

5-channel

digital

connection,

or

a

7-channel

digital

con

nections.

Other

examples

of

media

receiver

connections

are

also

possible.

These

media

receiver

connections

may

corre

spond

directly to

the

connections

available

on

the

media

receiver

38.

and

a

6-channel

audio

connection

(eg

for

use

With

5.1

modes)

56.

Audio

signals

received

at

the

media

receiver

38

may

be

played

through

one

or

more

speakers

coupled

to

the

media

receiver.

As

an

example,

the

media

receiver

38

is

shoWn

connected

to

a

?rst

speaker

40

(e.

g.

a

speaker

for

a

left-audio

channel), a

second

speaker

42

(eg

a

right-channel

speaker),

and

a

third

speaker

44

(eg

a

speaker

for

a

center-audio

channel).

Other

examples

of

the

amount

of

speakers

coupled

to

the

media

receiver

38

and/or

the

audio

signal

played

through

a

particular

speaker

are

also

possible.

The

media

receiver

38

may

also

drive

video

equipment,

such

as

a

television

or

monitor

36

via a

video

connection

58.

In

this

regard,

a

video

signal

59

is

sent

to

the

television

or

monitor

36.

The

video

formats

may

include

compressed

media

(video

and/or

audio

content),

uncompressed

media,

or

a

combination of

compressed

and

uncompressed

media.
