FIELD

OF

THE

INVENTION

The

present

invention

relates

to

the

distribution

of

multi

media

from

one

location

to

another.

More

particularly,

this

invention

relates

to

the

automated

distribution

of

digital

media,

most

preferably

by

‘pushing’

media

to

receiving

units

and

‘pulling’

media

from

distributing

units.

BACKGROUND

There

has

long

been

a

need

for

ef?cient

methods

and

sys

tems

for

distribution

of

differing

types

of

media

such

as

data,

images,

audio,

or

video

information.

In

attempting

to

ful?ll

this

need,

a

Wide

variety

of

types

of

systems

have

been

devel

oped,

from

manual

systems

such

as

postal

and

express

physi

cal

delivery

systems

to

digitiZed

systems

such

as

those

built

around

Wide

area

computing

netWorks

(WANs)

and

the

Inter

net.

Manual

systems

suffer

from

a

Wide

variety

of

problems,

such

as

high

cost,

limited

reach,

unreliability,

and

time

delay.

The

Internet

and

traditional

e-mail

types

of

distribution

sys

tems

have

become

have

become

a

much

more

omnipresent

vehicle

for

distributing

media,

but

the

Internet

presents

sig

ni?cant

problems

for

those

seeking

to

reliably,

ef?ciently,

and

quickly

distribute

digital

media,

particularly

voluminous

media

?les,

to

a

variety

of

users.

In

this

regard,

the

Internet

does

presently

support

certain

types

of

‘push’

distribution

and

‘pull’

distribution.

Internet

facilities

such

as

traditional

e-mail

alloW

an

Internet

user

to

‘push’

content

out

to

many

other

Internet

users

(but

usually

not

other types

of

users)

through

the

Internet.

Through

the

Web

and

other

facilities,

the

Internet

alloWs

Internet

users

(again,

not

others)

to

log

onto

Web

sites

and

‘pull’

or

doWn

load

content

from

the

sites.

The

Internet

‘pull’

model

of

distribution

is

unreliable

and

often

quite

untimely

because

it

requires

the

receiving

party

to

have

access

to

the

Internet

and

to

initiate

on

its

oWn

the

‘pull’

or

media

doWnload.

Similarly,

the

Internet

‘push’

model

of

distribution

is

either:

(i)

unreli

able

and

untimely

because

it

does

not

accomplish

any

deliv

ery

at

all

until

the

intended

receiving

party

logs

onto

the

Internet

and

retrieves

the

pushed

e-mail

content

from

the

party’s

e-mail

facility;

or

(ii)

expensive

if

the

‘push’

model

is

made

more

reliable

by

a

permanent

connection

to

the

Internet

by

all

desired

receiving

parties.

Moreover,

While

the

Internet

can

serve

as

an

effective

plat

form

for distribution

of

relatively

small

e-mail

messages

to

those

Who

have

corporate

or

educational

LANs

permanently

connected

to

the

Internet

24

hours

per

day,

7

days

per

Week,

the

Internet

is

not

effective

When

timing

of

the

reception

is

important

and

the

sending

and

receiving

entities

either

do

not

both

have

access

to

the

Internet

or

are

not

both

on-line

to

send

and

receive

When

needed.

The

Internet

also

suffers

from

Well

bandWidth

and

other

constraints

that

make

it

and

often

impossible,

to

rely

on

the

Internet

to

distribute

large

media

?les,

such

as

those containing

images,

audio,

or

video,

for

use

by

others

Who

must

receive

and

use

such

?les

in

a

timely

fashion.

One

approach

to

solving

the

problem

of

distribution

of

digital

media

has

been

to

develop

private

Wide

area

netWorks

(“WANs”)

independent

of

the

public

Internet.

Examples

of

these

types

of

systems

include

corporate

WAN’s

and

the

private

WAN

audio

distribution

systems

deployed

by

compa

nies

like

Digital

Courier

International

and

Musicam

Express.

entitled

“Audio

File

Distribution

and

Production

Sys

tem”).

These

private

WANs

often

consist

of

netWorks

of

(of

ten

specialiZed)

personal

computers

linked

through

dedi

cated,

private

telecommunications

types

of

links

in

order

to

produce

and

distribute

digital

information

and

media

from

one

computer

on

the

netWork

to

another.

These

types

of

prior

art

WAN’s

have

limited

reach

since

they

usually

are

connected

only

to

those

users

Who

have

systems

connected

to

the

WAN.

They

also

typically

have

required

dedicated

telecommunications

connections

for

each

machine

on

the

WAN

in

order

to

assure

accessibility

of,

and

push

distribution

to,

each

machine

on

the

WAN.

They

also

typically

have

required

use

of

substantial

expensive

propri

etary

or

non-standard

softWare

systems

in

order

to

reliably

distribute

voluminous

media

information,

particularly

audio

or

video

content,

throughout

the

WAN.

In

addition,

these

prior

art

systems

have

typically

required

deployment

of

many

thousands

of

expensive,

customiZed

PC’s

for

use

by

each

receiving

or

producing

entity

on

the

WAN.

These

types

of

WANs

have

thus

not

only

required

huge

expense

and

effort

required

to

manufacture,

deploy,

and

install

the

customiZed

PC’s

to

establish

the

WAN

and

to

achieve

the

distribution

sought

by

the

WAN,

but

also

inher

ently

limited

the

ability

to

easily

and

economically

upgrade

the

installed

base

of

PC’s

and

other

netWorking

equipment

over

time

When

hardWare

upgrading

is

required

or

advisable

(as

it

so

often

is

in

the rapidly

evolving

?eld

of

personal

computers

and

telecommunications).

BRIEF

SUMMARY

OF

ASPECTS

OF

THE

INVENTION

The

applicants

have

developed

an

integrated

and

auto

mated

system

and

method

for

reliably

distributing

digitiZed

media

information

(preferably

any

type

of

digitiZed

media

information

Whatsoever)

to

multiple

recipients.

The

present

system

and

method

includes

push

distribution

through

terres

trial

and/or

extraterrestrial

facilities

With

con?rmation

of

delivery

from

the

recipients,

and

a

combination

push-pull

distribution

by

a

contact

With

the

intended

recipient

(prefer

ably

Without

incurring

any

substantial

communication

charges)

and

a

responsive

pull

or

doWnloading

of

information

by

the

recipient,

also

With

con?rmation

by

the

recipient.

The

applicants’

system

and

method

also

preferably

includes

pull

distribution,

independent

of

the

push/pull,

alloWing intended

recipients

to

call

in

on

their

oWn

and

then

select

and

doWnload

information.

The

system

and

method

further

preferably

includes

an

automatic

fallback

method

of

physically

shipping

information

to

intended

recipients

that

have

not

con?rmed

receipt

of

the

media

information

through

the

other

push,

push/pull,

or

pull

methods.

The

preferred

system

and

method

also

provides

that

many

of

those

connected

to

the

system

may

be

producers
