1. Technical Field
The present invention relates generally to video display units such as televisions and monitors (including but not limited to computer monitors), and more particularly to communicating video-image content and optionally also audio content to such video display units for playback.
2. Background Art
The variety of electronic systems in the modern household continues to grow.
Turning first to the TTV systems 14, the predominant end-user device here is a television 18, with
The first television 18a is a big screen, high definition plasma unit (say, a 52″ screen, 1080 native resolution, 120 Hz unit presently costing US$2,500). To facilitate operation of the first television 18a, the user employs a remote controller 20 (here a first remote controller 20a). Of particular importance herein, the first television 18a in our hypothetical household is connected to a service box 22 (here a first service box 22a) that is connected to a service portal 25 (described in more detail presently). Of further importance, this first service box 22a has an integrated digital video recorder (DVR unit 24) and a set of network ports 26. And in typical manner, the first remote controller 20a here additionally is used to control the first service box 22a and the DVR unit 24.
The second television 18b is a medium size LCD unit (say, a 40″ screen, 720 native resolution unit presently costing US$1,000). Also of importance for what follows, the second television 18b is connected to a second service box 22b that is also connected to the service portal 25 and a separate digital video disk player (DVD player 28, here generically representing any of video tape players, laserdisc players, conventional DVD players, HD-DVD players, Blu-ray (TM) disc players, etc.) is connected between the second television 18b and the second service box 22b. The user here employs a second remote controller 20b to control all of the second television 18b, the second service box 22b, and the DVD player 28.
The third television 18c is a near antique. It is a 10-year old picture tube based unit with a “rabbit ears” antenna and might fetch US$50 at a yard sale, but its owner keeps it in the garage to occasionally watch baseball games or soap operas when waxing the car. The third television 18c is manually controlled (no remote controller) and it is not connected to the service portal 25.
The equipment in the TTV systems 14 thus performs entertainment functions, playing video content on the televisions 18, with the other equipment here providing communications to support this.
Turning next to the P/H systems 16, there is no predominant end-user device here but this equipment can collectively be viewed as having many “brain” like functions, including logic-based processing, data storage, and communications handling capability. As can be seen in
In the P/H systems 16 the brain-like functionalities are very powerful, being flexibly configurable, distributable, extendable, etc. For example, the logic-based processing functionality of the PC 30, laptop computer 32, or even the PDA 34 can be applied to virtually any task where data for that task can be communicated to and from these devices. The home kiosk 38 also has logic-based processing and, although typically dedicated to home utility control tasks, there is no inherent reason for this limitation and the utility control tasks performed by the home kiosk 38 might instead, for instance, be performed by the PC 30 when it is turned on. Similarly, the data storage functionality among the P/H systems 16 is noteworthy, being especially distributable and extendable. For example, a spreadsheet prepared on the PC 30 can be moved to the laptop computer 32 or a grocery list accumulated at the home kiosk 38 can be copied to the PDA 34. Our household members here also may have extensive multimedia collections (e.g., photographs, home videos, purchased music recordings, etc.) stored as files in the PC 30, laptop computer 32, or especially in the NAS 36. These are also easily moved or copied across the LAN 40 and, if these collections grow, more storage capacity can easily be added, say, in the NAS 36 or the PC 30. In particular however, it should be observed that all of the P/H systems 16 here can communicate across the LAN 40 and via it onto and across the Internet 46.
The problem in all of this, unfortunately, is that the P/H systems 16 generally cannot communicate with the TTV systems 14 because the TTV systems 14 will not “listen.” Even though the service boxes 22 and the modem 44 here in this example are physically connected to the very same service portal 25 via cable, the service boxes 22 typically are configured by their providers to “listen” only to what those service providers send as instructions or entertainment content. Thus, if a member of our hypothetical household has an AVI format video file stored on the NAS 36 they typically cannot play this on the big screen of the first television 18a. Or if another member of our hypothetical household has a MP3 audio file stored in the PDA 34 they cannot play this on the speakers of the second television 18b in the master bedroom. While especially the first television 18a and even the second television 18b represent substantial financial investments, each quite possibly costing more than any single unit among the P/H systems 16, access to the televisions 18 is effectively held hostage by the cable/satellite service providers of the service boxes 22 or else is not technically practical.
To say that cable/satellite service providers hold their customers “hostage” may seem overly blunt, but it is all to often true today. Most cable and satellite services are monopolies, either outright or effectively, and television owners that want cable or satellite service rarely have more than two or three suspiciously similar choices. In the case of cable service, a municipality or some other regional government entity usually enforces a geographically defined monopoly, selling the “cable rights” in that region to a single service provider. Similarly, satellite service today is effectively a monopoly because of the very high capital investment required to provide satellite based service and in the United States, for instance, there are effectively only two satellite service choices currently available.
As a result of this situation, the service boxes 22 shown in
Thus, as some additional examples, a member of our hypothetical household in
Before concluding here with
Accordingly, what is need is a system to bridge at least the divide 10 between the TTV systems 14 and the P/H systems 16, and additionally to bridge the sub-divides 48, 50 among groupings of TTV systems 14.
Turning away now from the problem towards the inventor's solution for it, it should be noted that many aspects of the underlying display technologies involved here are conventional. In the interest of summarizing some major aspects of this and establishing some of the terminology that is used herein, the following additional background information is provided.
a-b (background art) are of a video display unit (VDU 60), wherein
Starting with
Other than a housing or cabinet 62, the salient visual feature of the VDU 60 here is the front of a display screen 64 that displays images. The images may be single or “still” images (hereinafter “image content”), but more typically these are related sets of images that are perceived as video or moving pictures (hereinafter “video content”; and hereinafter “visual content” when either content can be applicable). The salient audible feature of the VDU 60 here is one or more speakers 66 that play sounds (two in a simple stereo arrangement are shown). The sounds usually are sequences of many sounds (hereinafter “audio content”) that typically (but not necessarily) are in some way related to visual content being presented on the display screen 64 of the VDU 60. A less prominent feature of the VDU 60 is a set of controls 68 that a user can use to change the various functions of the VDU 60 (e.g., powering it on or off, selecting what visual and/or audio content is played, and setting playback characteristics for such content, like color balance, volume, etc.). Historically the various controls 68 of early VDUs 60 operated manually, and most VDUs 60 still have at least limited capability for this, but the overwhelming case today is to employ a remote controller 70 to remotely and wirelessly operate the controls 68.
Turning now also to
VDU 60. The cabinet 62, display screen 64, speakers 66, controls 68, and remote controller 70 are all again shown. Additionally shown here are a power section 72, a signal receiver section 74, a video-image processing section 76, an audio processing section 78, and a controlling section 80. The power section 72 is physically connected to an external power source (not shown) to receive and distribute power as needed throughout the VDU 60. The signal receiver section 74 is physically connected to an external signal source (not shown) to receive visual and audio content, and to distribute it to the video-image processing section 76 and the audio processing section 78. Although many modern VDUs 60 can receive visual content and audio content as separate signals, most commonly these are received as an integrated signal (often also with an ability to select among individual or multiple such integrated signals provided from multiple external signal sources), and the signal receiver section 74 here is therefore depicted as a single unit. The video-image processing section 76 processes the received visual content as needed to present it on the display screen 64. Depending on the nature of how the visual content is received as a signal and on how a user of the VDU 60 wants to view this content, this can entail considerable work and sophisticated circuitry but this is not particularly relevant here. Similarly, the audio processing section 78 process the received audio content as needed to present it on the speakers 66. And also similarly, depending on the nature of how the audio content is received as a signal and how a user of the VDU 60 wants to perceive it, this also can entail considerable work and sophisticated circuitry but this also is not particularly relevant here. The controlling section 80 controls all of this functionality, subject to established default settings or changes made by a user with the controls 68. The controlling section 80 will vary in capability and the circuitry used for this, depending on the designed purpose of the VDU 60.
The reader by now has probably observed that the generic VDU 60 just described resembles a monitor or a television. [As an aside, the term “computer monitor” is herein avoided because this unduly implies use only with a computer.] Both monitors and televisions are, of course, major classes of VDUs 60.
Historically, monitors have not included speakers or an audio processing section. But this is no longer always the case. Some monitors today do include speakers or a capability to attach them as an option, and some monitors today include an audio processing section to provide audio content to such speakers. Furthermore, some VDU manufacturers now market monitors (often “computer monitors”) as being television-capable. With reference briefly back to
Televisions are VDUs 60 that are particularly characterized by having a tuning capability in their signal receiver section 74, to permit reception of and selection (via the controlling section 80) among multiple channels of visual and audio content. Early televisions received “television channels” (signals with integrated video and audio content) that were broadcast by radio waves). An antenna was the external signal source used to receive this and provide it to the signal receiver section, where tuning to a particular channel ensued. A major evolutionary enhancement of this was the advent of cable distribution of television channels, which continues today also with satellite distribution now being common. In the cases of both cable and satellite television channel distribution, however, the underlying television remains essentially the same. With reference again briefly back to
Accordingly, it is an object of the present invention to provide a network accessible display.
Briefly, one preferred embodiment of the present invention is a network accessible display. A video display unit including a display screen, a video-image processing circuit, an audio processing circuit, and a controlling circuit is provided. The video-image processing circuit plays visual content on the display screen and the audio processing circuit plays audio content on one or more speakers that are physically integrated into or externally connected to the video display unit. The controlling circuit directs functions of the video display unit. And a communications circuit is further provided to wirelessly connect the video display unit to a local area network to receive the visual and audio content for playback with the video display unit.
Briefly, another preferred embodiment of the present invention is an improved television of the type in which a video-image processing circuit plays visual content on an integrated display screen and an audio processing circuit plays audio content on one or more integrated or externally connected speakers and a controlling circuit directs functions of the television. The improvement comprises a communications circuit integrated into the television to wirelessly connect to a local area network to receive the visual content and the audio content via said local area network for playback by the television.
And briefly, another preferred embodiment of the present invention is a communications circuit to connect a video display unit to a local area network to receive visual content and audio content for playback. A wireless fidelity (WiFi) type receiver is provided to wirelessly receive the visual and audio content from the local area network. Interface circuitry is provided to communicate the visual and audio content from the communications circuit to the video display unit. And a processor and a logic running therewith are provided that controllably receive the visual and audio content and play it back with the video display unit.
These and other objects and advantages of the present invention will become clear to those skilled in the art in view of the description of the best presently known mode of carrying out the invention and the industrial applicability of the preferred embodiment as described herein and as illustrated in the figures of the drawings.
The purposes and advantages of the present invention will be apparent from the following detailed description in conjunction with the appended figures of drawings in which:
a-b (background art) are of a video display unit (VDU), wherein
In the various figures of the drawings, like references are used to denote like or similar elements or steps.
A preferred embodiment of the present invention is a network accessible display (NAD). This is illustrated in the various drawings herein, and particularly in the views of
Briefly and very basically, the inventive NAD 100 is essentially a conventional video display unit to which a communications circuit 102 has been added.
Since the communications circuit 102b here is external to the NAD 100b, a conventional remote controller like the second remote controller 20b (
First, because the externally added communications circuit 102b here typically will not be able to control the second television 18b (e.g., change speaker volume, etc.), the communications circuit 102b of the NAD 100b here will likely have to appear to a conventional remote controller as an additional device being controlled. In the scenario depicted in
There is also a second reason that using a conventional remote controller with an externally added communications circuit, like the communications circuit 102b here in
Digressing briefly, it should also be recalled that the old third television 18c in the garage in the scenario in

Of course, the circuitry in VDUs 60 is typically much more integrated than what is shown in
Once the overall inventive principles covered above are appreciated, the elements of the communications circuit 102a are largely straightforward. The major elements include a WiFi receiver 110 (here having an optional WiFi transmitting capability as well; Wi-Fi (TM) is short for “Wireless Fidelity” and is a radio communications protocol based on technology is based on IEEE 802.11 standards), a processor 112, logic 114 that controls the processor (here shown as firmware), and general interface circuitry 116.
While various embodiments have been described above, it should be understood that they have been presented by way of example only, and that the breadth and scope of the invention should not be limited by any of the above described exemplary embodiments, but should instead be defined only in accordance with the following claims and their equivalents.
