Abstract
An XBOX optical connector has a miniature phone plug at one end of an adapter cable. The phone plug plugs into a jack provided in a console connector that plugs into the console of an XBOX game machine. A semiconductor laser modulator optical transmitter that modulates digital audio signal data onto a laser light beam is provided. The optical transmitter is powered by 5 volts dc received from the game console. The digital audio signal data is received from the game console, is conducted by the adapter cable, and provided to a television set by means of an optical connector provided at the other end of the adapter cable.
Description
TECHNICAL FIELD OF THE INVENTION
The present invention relates to cabling between a game machine console and a television set and, more particularly, to an adapter employing fiber optics to conduct digital audio signals from a game machine to a television set.
BACKGROUND OF THE INVENTION
Microsoft has developed a game machine called XBOX which has a console that connects to a television set by means of a special cable referred to as a “High Definition AV Pack”. This “pack” connects the console of the XBOX game machine to standard or high definition ready television sets that support 480 pixel, 720 pixel, and 1080i component video signals, analog audio inputs, and/or digital receivers or to audio systems. This “High Definition AV Pack” comprises a multiconductor cable with a console connector at one end, and a connector connector block at the other end having a plurality of RCA connector jacks. Additional cables connect from the connector block to the television set. The connector block has a fiber optic connector at one end to provide for using a fiber optic cable to conduct digital audio to the television set.
This “High Definition AV Pack” provided by Microsoft for use between the XBOX game machine console and a high definition ready television set is cumbersome, inconvenient, expensive and confusing. It requires the purchase of extra cables to connect from the RCA connector jacks in the connector block to the television set. Accordingly, there is a need for an improved XBOX optical adapter that eliminates the foregoing disadvantages of the Microsoft cable.
SUMMARY OF THE INVENTION
In accordance with the principles of the present invention, there is provided a console connector cable that connects directly to the television set. The cable has a console connector at one end, and has connectors that mate with the connectors on the television set at the other end. For those audio systems that support digital audio, a special optical adapter is provided. It comprises an adapter cable having a miniature phone plug at one end that plugs into a jack provided in the console connector. At the other end, the adapter cable is provided with a fiber optic connector that mates with a fiber optic connector provided on the audio systems. The connector includes a semiconductor laser modulator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1
is a block diagram illustrating a game machine
10
connected by a cable
11
to a television set or audio system
12
. In the preferred embodiment, the game machine
10
is of the type referred to as the XBOX manufactured by Microsoft. The primary purpose of the game machine
10
is to permit the user to play high tech games, but it may also be used to play music via a CD player and to play movies via a DVD player. The television set or audio system
12
may be a high definition ready television that supports 480 pixel, 720 pixel, or 1080i component video signals, analog audio inputs, and/or digital receivers. Alternatively, the television set
12
may be a home theater video projector with stereo surround sound, or other types of television sets or monitors. The cable
11
may be a “High Definition AV Pack” or any other multiconductor cable having a console connector at one end to connect to the game machine
10
, and being adapted to connect to the television set or audio system
12
at the other end. The cable
11
may also include a fiber optic cable to conduct digital audio from the game machine
10
to a television set or audio system
12
that supports digital audio.
Referring now to
FIG. 2
, there is shown a schematic diagram of an XBOX “High Definition AV Pack”
20
as provided by the manufacturer of the game machine
10
. The “High Definition AV Pack”
20
comprises a console connector
21
, a multiconductor cable
22
connected to the console connector
21
, and a connector block
23
connected to the other end of the multiconductor cable
22
. The connector block
23
is provided with a plurality of RCA connector jacks
24
, and an optical connector
25
at one end.
Referring now to
FIG. 3
, there is shown a schematic view of a modified console connector
21
a
provided with a jack
30
for receiving a miniature phone plug. Referring now to
FIG. 4
, there is shown a schematic view of connectors
31
employed to connect the console connector
21
a
of
FIG. 3
to the television set or audio system
12
of FIG.
1
. Referring now to
FIG. 5
, there is shown a schematic diagram of an XBOX optical adapter
36
that is provided with a miniature phone plug
37
that plugs into the jack
30
shown in FIG.
3
. The optical adapter
36
employs an adapter cable
38
that terminates in an optical connector
40
that connects to the television or audio system
12
shown in FIG.
1
. The optical connector
40
is a standard rectangular connector of the type conventionally used to terminate fiber optic cables known as a TOS link fiber optic transmitter. The optical connector
40
is mounted in a terminating block
41
attached to the adapter cable
38
. The terminating block
41
contains a semiconductor laser modulator optical transmitter
50
, represented as a dashed block, that modulates digital audio signals onto a laser light beam. The miniature phone plug
37
is a standard stereo mini plug having a tip
42
, a ring
43
, and a sleeve
44
. The miniature phone plug is 2.5 mm in diameter. It receives 5 volts dc on the tip
42
to power the semiconductor laser modulator optical transmitter that is within the terminating block
41
. The ring
43
conducts the digital audio data. The sleeve
44
is the ground connection for the 5 volts dc and for the digital audio data.
Thus, there has been described an XBOX optical adapter
36
in accordance with the present invention for use with an XBOX game machine
10
to conduct digital audio signals to a television set
12
that supports digital audio signals. The XBOX optical adapter
36
of the present invention provides better performance, and is cheaper, more convenient and less confusing than the cables used heretofore.
It will be appreciated by those skilled in the art that there can be departure from the specific embodiment of the invention described herein without departing from the true scope of the claims appended hereto.
