FOR

SATELLITE

TELEVISION

SYSTEM

FIELD

OF

THE

INVENTION

[0001]

The

present

invention

relates

to

television

con

verter

devices.

More

speci?cally,

the

invention

provides

a

method

and

apparatus

for

Wirelessly

communicating

to

a

television

converter

device.

BACKGROUND

OF

THE

INVENTION

[0002]

The

prior

art

includes

various

devices

Which

can

be

used

to

receive

pay-television

signals.

Pay

television

service

involves

a

pay

television

distributor

sending

television

sig

nals

to

subscribers.

These

subscribers

are

given

or

pay

for a

television

converter.

Television

converters

are

commonly

knoWn

as

cable

boxes

or

satellite

television

set-top-boxes.

These boxes

receive

and decode

the

pay-television

signal

for

authoriZed

display

on

a

television

set

or

monitor.

[0003]

Many

of

the

pay-television

distributors

need

to

receive

communications

from

set-top-boxes.

Communica

tions

may

include

pay-per-vieW

purchase

records

or

other

types

of

information.

These

communications

may

be

shoWn

on

the

television

or

may

affect

the

operation

of

the

set-top

box.

[0004]

Many

current

pay-television

systems

utiliZe

a

phone

line

connected

to

the

set-top-box.

The

phone

line

acts

as

a

communications

pathWay

betWeen

the

pay-television

distributor

and

the

subscriber.

It

is

desirable

to

provide

an

alternative

communications

pathWay Where

a

phone

line

is

not

available

or

not

connected.

Sometimes

the

subscriber

installs

the

television

system

or

set-top-box

Where

a

phone

line

is

not

available.

In

recent

years,

many

people

have

sWitched

exclusively

to

Wireless

or

cellular

phones

and

may

not

have

a residential

telephone

line to

communicate

to

the

pay-television

distributor.

In

other

installations,

the

sub

scriber

fails

to

or

forgets

to

connect

the

phone

line.

In

some

situations,

the

subscriber

may

simply

refuse

to

install

the

phone

line.

Thus,

there

exists

a

need

to

provide

a

commu

nications

pathWay

betWeen

the

subscriber

and

the

pay

television

distributor

that

does

not

rely

on

a

landline

phone.

There

also

exists

a

need

for a

communications

pathWay

betWeen

the

set-top-box

to

the

pay-television

distributor

that

cannot

be

inadvertently

or

intentionally

disconnected

by

a

subscriber.

[0005]

Some

subscribers

Who

do

not

have

access

to

a

landline

phone

line

may

nevertheless

also

Wish

to

connect

a

landline

telephone

unit

for

use

With

this

alternative

commu

nications

pathWay.

A

need

therefore

exists

to

permit

the

use

of

a

subscriber’s

conventional

landline

telephone

unit

via

the

alternative

communications

pathWay.

BRIEF

SUMMARY

OF

THE

INVENTION

[0006]

The

present

invention

solves

the

above

problems

by

attaching

a

Wireless

phone

device

and

antenna

to

the

set-top-box.

This

Wireless

phone

system

transmits

data

betWeen

the

subscriber’s

box

and

a

Wireless

netWork.

The

cellular

netWork

may

relay

the

data

to

the

pay-television

distributor.

Other

features

and

advantages

of

the

present

invention

Will

become

apparent

from

the

folloWing

detailed

description

of

the

invention

and

the

accompanying
