Abstract
A flat screen videophone has a microprocessor card located behind the video display, and an associated keyboard, and can be supported for convenient use in a variety of locations, such as on a wall, under a cabinet or shelf, or on a desk or counter. Wall-mounted versions suspend the keyboard on an adjustable bracket which holds the keyboard in an oblique use position, or in a storage position flat against the wall below the videophone housing. On under-cabinet versions the bracket-mounted keyboard can be swung behind the housing for storage, while the housing can be slid to the rear for storage, or swung upwardly for storage. Desk-top models have one or more cradles for storing the keyboard flat against the housing.The housing can support peripheral devices, such as a printer, a scanner or a fax machine. Other devices may include a microphone, a camera, a motion sensor, a light sensor, a card reader, a telephone handset, and loudspeakers.
Description
TECHNICAL FIELD
This invention relates to videophones and, more particularly, to space-saving videophones adapted for convenient use in a variety of locations.
BACKGROUND
As deregulation of the telephone industry continues and as companies prepare to enter the local telephone access market, there is a need to offer new and innovative services that distinguish common carriers from their competitors. This cannot be accomplished without introducing new local access network architectures that will be able to support these new and innovative services.
Conventionally, customer premises telephone and/or data connections contain splitters for separating analog voice calls from other data services such as Ethernet transported over digital subscriber line (DSL) modems. Voice band data and voice signals are sent through a communications switch in a central or local office to an interexchange carrier or Internet service provider. DSL data is sent through a digital subscriber loop asynchronous mode (DSLAM) switch which may include a router. The DSLAM switch connects many lines and routes the digital data to a telephone company's digital switch.
A major problem with this configuration is that interexchange carriers attempting to penetrate the local telephone company's territory must lease trunk lines from the local telephone company switch to the interexchange company's network for digital traffic. Furthermore, the Internet service provider must lease a modem from the local phone company in the DSLAM switch and route its data through the local phone company's digital switch. Thus, the local phone company leases and/or provides a significant amount of equipment, driving up the cost of entry for any other company trying to provide local telephone services and making it difficult for the interexchange companies to differentiate their services. Furthermore, since DSL modem technology is not standardized, the DSL modem provided by the local telephone company must also be provided to the end user in the customer premises equipment (CPE) in order to ensure compatibility. Additionally, since the network is not completely controlled by the interexchange companies, it is difficult for the interexchange companies to provide data at committed delivery rates. Any performance improvements implemented by the interexchange companies may not be realized by their customers, because the capabilities of the local telephone company equipment may or may not meet their performance needs. Thus, it is difficult for the interexchange companies to convince potential customers to switch to their equipment or to use their services. These factors ensure the continued market presence of the local telephone company.
As part of this system, there is a need for improved architectures, services and equipment utilized to distinguish the interexchange companies' products and services. Existing videophones either make use of large and bulky desktop computer monitors, or are rather large and bulky stand-alone units that take up considerable desk or counter space. This invention addresses the need for greater compactness and versatility in videophones.
SUMMARY OF THE INVENTION
In order to provide an improved network, it is desirable for the interexchange companies to have access to at least one of the twisted-pair lines or alternate wireless facility connecting each of the individual users to the local telephone network before the lines are routed through the conventional local telephone network equipment. It is preferable to have access to these lines prior to the splitter and modem technology offered by the local service providers. By having access to the twisted-pair wires entering the customer's premises, interexchange companies can differentiate their services by providing higher bandwidth, improving the capabilities of the customer premises equipment, and lowering overall system costs to the customer by providing competitive service alternatives.
The new architecture may utilize a videophone and/or other devices to provide new services to an end user; an intelligent services director (ISD) disposed at or near the customer's premises for multiplexing and coordinating many digital services onto a single twisted-pair line; a facilities management platform (FMP) disposed in the local telephone network's central office for routing data to an appropriate interexchange company network; and a network server platform (NSP) coupled to the FMP for providing new and innovative services to the customer and for distinguishing services provided by the interexchange companies from those services provided by the local telephone network.
As part of this system, the invention provides a space-saving flat screen videophone which can be mounted in many convenient locations, and has functional features which make it a highly versatile telecommunications tool.
In accordance with one aspect of the invention, the videophone has a housing, a substantially flat panel video display of the front of the housing, a microprocessor card in the housing behind the video display, and means for mounting the housing on a substantially vertical surface, such as a wall. An adjustable bracket secures an associated keyboard to the housing.
For alternate mounting under a substantially horizontal surface, such as a cabinet or a shelf, the videophone according to the invention includes a housing support which suspends the housing below the horizontal surface. In these suspended embodiments, the bracket-supported keyboard can be stored behind the housing, and the housing either slid back to a storage position, or pivoted upwardly to a storage position.
For desktop support, the videophone according to the invention has a support base. The keyboard can be stored in a cradle either at the front of the housing, or at the rear.
The microprocessor card for the videophone preferably is a plug-in unit, which is accessible through an access opening in the housing.
The videophone also can be mated with one or more housing-supported peripheral devices, such as a printer, a scanner a facsimile machine or a postage meter. It also may be equipped with various built-in devices, such as a microphone, a camera, a motion sensor, a light sensor, a card reader, a telephone handset, or a loudspeaker.

DETAILED DESCRIPTION
Referring to
FIG. 1
, a first exemplary communication network architecture employing a hybrid fiber, twisted-pair (HFTP) local loop
1
architecture is shown. An intelligent services director (ISD)
22
may be coupled to a central office
34
via a twisted-pair wire, hybrid fiber interconnection, wireless and/or other customer connection
30
, a connector block
26
, and/or a main distribution frame (MDF)
28
. The ISD
22
and the central or local office
34
may communicate with each other using, for example, framed, time division, frequency-division, synchronous, asynchronous and/or spread spectrum formats, but in exemplary embodiments uses DSL modem technology. The central office
34
preferably includes a facilities management platform (FMP)
32
for processing data exchanged across the customer connection
30
. The FMP
32
may be configured to separate the plain old telephone service (POTS) from the remainder of the data on the customer connection
30
using, for example, a tethered virtual radio channel (TVRC) modem (shown in FIG.
4
A). The remaining data may be output to a high speed backbone network (e.g., a fiber-optic network) such as an asynchronous transfer mode (ATM) switching network. The analog POTS data may be output directly to a public switch telephone network (PSTN)
46
, and/or it may be digitized, routed through the high speed backbone network, and then output to the PSTN
46
.
The FMP
32
may process data and/or analog/digitized voice between customer premise equipment (CPE)
10
and any number of networks. For example, the FMP
32
may be interconnected with a synchronous optical network (SONET)
42
for interconnection to any number of additional networks such as an InterSpan backbone
48
, the PSTN
46
, a public switch switching network (e.g. call setup SS7-type network
44
), and/or a network server platform (NSP)
36
. Alternatively, the FMP
32
may be directly connected to any of these networks. One or more FMPs
32
may be connected directly to the high speed backbone network (e.g., direct fiber connection with the SONET network
42
) or they may be linked via a trunk line (e.g., trunks
40
or
42
) to one or more additional networks.
The NSP
36
may provide a massive cache storage for various information that may be provided across the SONET net
42
to the FMP
32
and out to the ISD
22
. The NSP
36
and the FMP
32
may collectively define an access network server complex
38
. The NSP
36
may be interconnected with multiple FMPs
32
. Furthermore, each FMP
32
may interconnect with one or more ISDs
22
. The NSP
36
may be located anywhere but is preferably located in a point-of-presence (POP) facility. The NSP
36
may further act as a gateway to, for example, any number of additional services.
The ISD
22
may be interconnected to various devices such as a videophone
130
, other digital phones
18
, set-top devices, computers, and/or other devices comprising the customer premise equipment
10
. The customer premise equipment may individually or collectively serve as a local network computer at the customer site. Application applets may be downloaded from the NSP
36
into some or all of the individual devices within the customer premise equipment
10
. Where applets are provided by the NSP
36
, the programming of the applets may be updated such that the applets are continually configured to the latest software version by the interexchange carrier. In this way, the CPE
10
may be kept up to date by simply re-loading updated applets. In addition, certain applets may be resident on any of the CPE
10
. These resident applets may be periodically reinitialized by simply sending a request from, for example, a digital phone
18
and/or a videophone
130
to the FMP
32
and thereafter to the NSP
36
for reinitialization and downloading of new applets. To ensure widespread availability of the new features made possible by the present architecture, the customer premise equipment may be provided to end users either at a subsidized cost or given away for free, with the cost of the equipment being amortized over the services sold to the user through the equipment.
Referring to
FIG. 2
, the ISD
22
may connect with a variety of devices including analog and digital voice telephones
15
,
18
; digital videophones
130
, devices for monitoring home security, meter reading devices (not shown), utilities devices/energy management facilities (not shown), facsimile devices
16
, personal computers
14
, and/or other digital or analog devices. Some or all of these devices may be connected with the ISD
22
via any suitable mechanism such as a single and/or multiple twisted-pair wires fiber and/or a wireless connection. For example, a number of digital devices may be multi-dropped on a single twisted-pair connection. Similarly, analog phones and other analog devices may be multi-dropped using conventional techniques.
The ISD
22
may be located within the home/business or mounted exterior to the home/business. The ISD
22
may operate from electrical power supplied by the local or central office
34
and/or from the customer's power supplied by the customer's power company. Where the ISD
22
includes a modem, it may be desirable to power the ISD
22
with supplemental power from the home in order to provide sufficient power to enable the optimal operation of the modem.
As shown in
FIG. 2
, in some embodiments the ISD
22
may include a controller
100
which may have any of a variety of elements such as a central processing unit
102
, a DRAM
103
, an SRAM
104
, a ROM
105
and/or an internet protocol (IP) bridge router
106
connecting the controller
100
to a system bus
111
. The system bus
111
may be connected with a variety of network interface devices
110
. The network interface devices
110
may be variously configured to include an integrated services digital network (ISDN) interface
113
, an Ethernet interface
119
(e.g., 10 Base T, 100 Base T, etc.), an IEEE 1394 “fire wire” interface
112
(e g., for a digital videodisc device (DVD)), a digital subscriber line TVRC modem interface
114
) (DL interface (e.g., a a residential interface
114
, (e.g., standard POTS phone systems such as tip ring), a business interface
116
(e.g., a T
1
line and/or PABX interface), a radio frequency (RF) audio/video interface
120
(e.g., a cable television connection), and a cordless phone interface
123
(e.g., a 900 MHZ transceiver). Connected to one of the network interfaces and/or the system bus
111
may be any number of devices such as an audio interface
122
(e.g., for digital audio, digital telephones, digital audio tape (DAT) recorders/players, music for restaurants, MIDI interface, DVD, etc.), a digital phone
121
, a videophone/user interface
130
, a television set-top device
131
and/or other devices. Where the network interface is utilized, it may be desirable to use, for example, the IEEE 1394 interface
112
and/or the Ethernet interface
119
.
A lifeline
126
may be provided for continuous telephone service in the event of a power failure at the CPE
10
. The lifeline
126
may be utilized to connect the ISD
22
to the local telecommunications company's central office
34
and, in particular, to the FMP
32
located in the central office
34
.
The ISD may be variously configured to provide any number of suitable services. For example, the ISD
22
may offer high fidelity radio channels by allowing the user to select a particular channel and obtaining a digitized radio channel from a remote location and outputting the digital audio, for example, on an audio interface
122
, videophone
130
, and/or digital phones
121
. A digital telephone may be connected to the audio interface
122
such that a user may select any one of a number of digital audio service channels by simply having the user push a digital audio service channel button on the telephone and have the speaker phone output particular channels. The telephone may be preprogramed to provide the digital audio channels at a particular time, such as a wake up call for bedroom mounted telephone, or elsewhere in the house. The user may select any number of services on the videophone and/or other user interface such as a cable set-top device. These services may include any number of suitable services such as weather, headlines in the news, stock quotes, neighborhood community services information, ticket information, restaurant information, service directories (e.g., yellow pages), call conferencing, billing systems, mailing systems, coupons, advertisements, maps, classes, Internet, pay-per-view (PPV), and/or other services using any suitable user interface such as the audio interface
122
, the videophone/user interface
130
, digital phones,
121
and/or another suitable device such as a set-top device
131
.
In further embodiments, the ISD
22
may be configured as an IP proxy server such that each of the devices connected to the server utilizes transmission control protocol/internet protocol (TCP/IP) protocol. This configuration allows any device associated with the ISD to access the Internet via an IP connection through the FMP
32
. Where the ISD
22
is configured as an IP proxy server, it may accommodate additional devices that do not support the TCP/IP protocol. In this embodiment, the ISD
22
may have a proprietary or conventional interface connecting the ISD
22
to any associated device such as to the set top box
131
, the personal computer
14
, the video telephone
130
, the digital telephone
18
, and/or some other end user device.
In still further embodiments, the ISD
22
may be compatible with multicast broadcast services where multicast information is broadcast by a central location and/or other server on one of the networks connected to the FMP
32
, e.g., an ATM-switched network. The ISD
22
may download the multicast information via the FMP
32
to any of the devices connected to the ISD
22
. The ISD
22
and/or CPE
10
devices may selectively filter the information in accordance with a specific customer user's preferences. For example, one user may select all country music broadcasts on a particular day while another user may select financial information. The ISD
22
and/or any of the CPE
10
devices may also be programmed to store information representing users' preferences and/or the received uni-cast or multicast information in memory or other storage media for later replay. Thus, for example, video clips or movies may be multicast to all customers in the community with certain users being preconfigured to select the desired video clip/movie in real time for immediate viewing and/or into storage for later viewing.

, a printer/scanner/facsimile
152
, and/or external speakers
154
(e.g., stereo speakers). A keyboard
153
and/or a postage scale
151
may also be connected to the videophone
130
. Any or all of the above-mentioned items may be integrated with the videophone unit itself or may be physically separate from the videophone unit. A block diagram of the videophone unit is shown in FIG.
3
B. Referring to
FIG. 3B
, in addition to the items above, the videophone
130
may also include a signal processor
171
, high speed interface circuitry
172
, memory
173
, power supply
174
, all interconnected via a controller
170
.
When the videophone
130
is used as a video telephone, the display
141
may include one or more video window(s)
160
for viewing a person to whom a user is speaking and/or showing the picture seen by the person on the other end of the videophone. The display may also include a dialed-telephone-number window
161
for displaying the phone number dialed, a virtual keypad
162
, virtual buttons
163
for performing various telephone functions, service directory icons

, a mail icon
164
, and/or various other service icons
166
which may be used, for example, for obtaining coupons or connecting with an operator. Any or all of these items may be displayed as virtual buttons and/or graphic icons and may be arranged in any combination. Additionally, any number of other display features may be shown on the videophone in accordance with one or more of the applications incorporated by reference below.
Referring to
FIG. 4A
, the FMP
32
may coordinate the flow of data packets, separate voice signals from other signals, perform line monitoring and switching functions, and/or convert between analog and digital signals. The FMP
32
may process data sent from the CPE
10
to the central or local office
34
by separating and reconstructing analog voice signals, data, and control frames. The FMP
32
may process data sent from the central or local office
34
to the CPE
10
by separating control messages from user information, and configure this information into segments that for transport across the digital subscriber loop. The FMP
32
may also terminate the link layer associated with the digital subscriber loop.
In some embodiments, the FMP
32
may include an access module
70
and a digital loop carrier
87
. The access module
70
may include a line protector
71
, a cross-connector
73
, a plurality of TVRC modems
80
, a plurality of digital filters
82
, a controller multiplexer
84
, and/or a router and facilities interface
86
. The digital loop carrier
87
may include a plurality of line cards
96
, a time domain multiplexing (TDM) multiplexor (MUX)
88
, a TDM bus
90
, a controller
92
, and/or a facilities interface
94
.
During normal operations, digital signals on the customer connection
30
(e.g., twisted-pair lines) containing both voice and data may be received by the TVRC modems
80
via the line protector
71
and the cross-connector
73
. Preferably, the line protector
71
includes lightning blocks for grounding power surges due to lightning or other stray voltage surges. The TVRC modems
80
may send the digital voice and/or data signals to the controller multiplexor
84
and the digital filters
82
. The digital filters
82
may separate the voice signals from the digital data signals, and the controller multiplexor
84
may then multiplex the voice signals and/or data signals received from the digital filters
82
. The controller multiplexor
84
may then send multiplexed voice signals to the TDM MUX
88
and the data signals to the router and facilities interface
86
for transmission to one or more external networks. The TDM MUX
88
may multiplex the voice signals from the controller multiplexor
84
and/or send the voice signals to the TDM bus
90
, which may then send the digital voice signals to the controller
92
and then to the facilities interface
94
for transmission to one or more external networks. Both the router and facilities interface
86
and the facilities interface
94
may convert between electrical signals and optical signals when a fiber optic link is utilized.
When there is a failure of the digital data link (e.g., if there is a failure of the TVRC modems
80
at the FMP
32
or the TVRC modem
114
at the ISD
22
), only analog voice signals might be sent over the subscriber lines
30
. In such a case, the analog voice signals may be directly routed to the line cards
96
, bypassing the TVRC modems
80
, the digital filters
82
, the controller multiplexor
84
, and the TDM MUX
88
. Thus, voice communication is ensured despite a failure of the digital data link. The line cards
96
may convert the analog voice signals into digital format (e.g., TDM format) and send the digitized voice data onto the TDM bus
90
and eventually through the controller
92
and the facilities interface
94
for transmission to one or more external networks.

232
, while the same links extend from the housing when the keyboard is deployed for use.
The support for keyboard
253
may take any form as long as it positions and supports the keyboard in the described positions. This would include any form of bracket at each end of the keyboard, or a single central bracket which supports the entire keyboard. Alternatively, the keyboard may be held in a tray or rack which itself is adjustably suspended from the housing.
FIGS. 8
,
9
a
and
9
b
depict a videophone
330
which is adapted for mounting below a substantially horizontal surface, such as beneath a cabinet C or shelf. The videophone may have all of the features shown in
FIGS. 3A and 3B
, including a printer/scanner/facsimile
352
, and similarly is paired with a keyboard
353
. Also included are cooling vents (not shown) along the top of housing
332
, and a microprocessor card access port closed by a cover
337
.
In the embodiment shown in
FIGS. 8 and 9
a
, the top of housing
332
is secured to and suspended from the movable elements of a pair of under-cabinet slides
360
. This enables videophone
330
to slide between a use position near the front edge of cabinet C (shown in solid lines in
FIG. 9
a
), and a rear storage position adjacent wall W (shown in dotted lines in
FIG. 9
a
). When in the use position, a suitable brake or lock (not shown) prevents the videophone from sliding backward.
Alternatively, the top of housing
332
may be pivoted to cabinet C in brackets
362
(
FIG. 9
b
) such that the videophone may be pivoted upwardly to a storage position against the bottom of the cabinet (shown in dotted lines in FIG.
9
(
b
). Here, too, a suitable brake or lock (not shown) prevents movement of the videophone from its use position, and also prevents the videophone from dropping from its storage position. Any other form of housing support may be used as long as it affords a similar degree of support, and storage away from the front edge of the cabinet or shelf.
In the embodiments shown in
FIGS. 8
,
9
a
and
9
b
, keyboard
353
is adjustably suspended from housing
332
on adjustable brackets
340
in a manner similar to that used in the wall-mounted embodiment of
FIGS. 5-7
. Here, however, the upper link
342
of each bracket
340
simply is pivoted to a bracket
343
on the rear of housing
332
, and the keyboard is stored behind the housing, with links
342
,
344
folded adjacent one another. Any other keyboard support may be used as long as it affords a similar degree of support, adjustment and storage.
FIGS. 10-12
depict a videophone
430
which is adapted for mounting on a substantially horizontal surface, such as desk, table or counter. The videophone may have all of the features shown in
FIGS. 3A and 3B
, including a printer/scanner/facsimile
452
, and similarly is paired with a keyboard
453
. Also included are cooling vents
435
along the top of housing
432
, and a microprocessor card access port closed by a cover
437
. Here, videophone
430
is supported on a pair of feet
460
, one near each side of housing
432
.
When not in use, keyboard
453
may be stored vertically in front of housing
432
in a front cradle comprising two spaced L-shaped brackets
470
FIGS. 10
,
11
). These brackets are attached to housing
432
just above printer/scanner/facsimile
452
, so that the document feed slot
454
of that peripheral device is not obstructed by the keyboard. Alternatively, housing
432
may be provided with a rear keyboard cradle comprising two spaced L-shaped brackets
480
(
FIG. 12
) which support the keyboard in a storage position behind the housing. The housing may be provided with both front and rear keyboard cradles to give the user two optional locations for storing the keyboard. The keyboard cradles may take any suitable form as long as they provide compact, substantially vertical support for the keyboard. For example, instead of using two discrete L-shaped brackets on either the front or the rear of housing
432
, a single elongated L-shaped cradle may be provided.
In any of the configurations illustrated in
FIGS. 5-12
, peripheral devices, such as printer/scanner
252
,
352
,
452
, may be mounted at any suitable location on the housing. For example, a combined printer/scanner may be mounted along the top of the housing instead of along the bottom. Another peripheral device may be mounted along the left side of the housing. Other combinations are considered to be encompassed within the invention as long as the generally flat configuration of the videophone is preserved.
