Description




FIELD OF THE INVENTION




The present invention pertains to computerized entertainment systems and to methods of constructing user interfaces for those systems.




BACKGROUND OF THE INVENTION




The home electronics industry, in the midst of an on-going convergence of televisions and computers, has produced a new class of products, known as PC-TV systems, or personal-computer-television systems. In their simplest form, these systems allow users to selectively switch between using a video monitor, or display, to watch television or to support computer activities, like word processing, creating spread sheets, playing computer games, or even surfing the world wide web. A seminal example, the Gateway Destination PC-TV system, from Gateway 2000, Inc., not only weds a television to a personal computer, but allows system expansion to receive programming from internal sources such as video-cassette recorders, laser-disc players, and video cameras and from external sources such as direct-broadcast-satellite receivers, etc.




In home entertainment systems, a number of devices are often interconnected. Such devices may include various components such as a VCR, laser disc player, a stereo receiver, speakers, a television, a CD-player/recorder, a tape deck, equalizers, amplifiers, and the like. Increasingly, personal computers, with their attendant peripherals such as a DVD-ROM drive, printer, scanner, mass storage, internet browsers and other programs, mouse or pointing device, and the like have been used in home entertainment systems.




One problem in owning and operating a PC-TV system concerns adding and controlling new components. Conventional PC-TV systems generally use a categorical, one-size-fits-all approach, to controlling new components and thus include a very basic set of controls for all external components. For example, these systems provide a basic VCR category which typically only includes play, stop, pause, fast-forward, and rewind commands. Yet, many VCRs include more functionality, such as frame advance, set-up menu, programming, and so forth which is inaccessible through these controls. Thus, the limited basic controls of conventional PC-TV systems are more or less useless with the broad range of extra functions inherent to many components.




Currently, there are several partial solutions to this problem. One is the DestiVu (tm) AV Panel which provides static user interface (UI) controls for categories of devices. Individual functionality of an attached device is not available in the DestiVu system.




Through the use of simplified templates, the user may use “least common denominator” interface elements. For example, any VCR identified as a VCR will have certain core functions, such as “play,” “record,” “stop,” and the like. Many VCRs have a wide variety of further functions not necessarily present on all VCRs. The “least common denominator” solution does not provide access to the further functionality.




A second is the Crestron wireless remote control touchpad provides a graphical user interface (GUI) on a large hand held touch sensitive input device. However, the user interface elements must be manually placed in the user interface by the end user of the system. Similarly, each component capable of attachment to a system has its own set of functions it is capable of performing. Not all components will have the same features, but each component in a device category will meet a minimum standard of functions. This minimum standard of core functions is called the “least common denominator.” Each device of a certain type will have at a minimum the “least common denominator” features.




Further, the Crestron solution uses a proprietary operating environment for generating its graphical user interface. The Crestron system is constructed to operate only on a proprietary platform. If the user is unaware of certain functions a device is capable of performing, the functionality of those features will not be present in the constructed user interface.




A third partial solution is the Phast Landmark (tm) system. The Phast system uses complex UI elements to describe many external devices. However, like the Crestron system, the Phast solution forces users to go through an elaborate manual setup procedure to define the interfaces for particular devices. In a windows environment, this entails a drop-and-drag technique. As in the Crestron system, if the user is unaware of certain functions a device is capable of performing, the functionality of those features will not be present in the constructed user interface.




Computer-based home entertainment systems are interconnecting an increasing number of components. Not all of these components can be connected directly to the computer-based controller. Current computer-based television solutions either support an internal tuner or tuners directly connected to an audio/video input on the computer based controller. Tunable devices such as televisions, stereo receivers, VCRs, satellite dishes, and the like are not supported by the current solutions if they are not connected directly to the computer-based controller. Tunable devices such as those described have a set of channels or stations which are available for viewing or listening.




Home entertainment systems may have a variety of peripheral devices connected together to from a complete system. Computers are increasingly more likely to be contained in such a home entertainment system. Peripheral devices are connectable to the system in any number of different configurations. A representative but not exhaustive list of such peripheral devices includes tunable devices such as television, VCR, Video Disk Player, Satellite Dish, and Stereo receiver. Each of these devices may be connected to various channel receiving components, such as an antenna, a satellite dish or satellite receiving system, a cable television cable, and combinations thereof. Further peripheral devices which may be connected to a computer-based home entertainment system may include, by way of example, DVD players, CD-ROMs, amplifiers, and equalizers. These further devices may also be connected to various channel receiving components, but are often connected simply to the computer via a direct connection to a computer-based controller or the like.




Accordingly, there is a need for a system with a much broader range of controls that can address the broad functionality not generally controllable using conventional control architectures.




SUMMARY OF THE INVENTION




To address these and other shortcomings, the inventor devised a computer-based system used to represent in a graphical user interface the interconnected components or peripheral devices of a home entertainment system. An embodiment of the computer-based system of the present invention includes a comprehensive database of device functionality capabilities, user interface elements, and channel maps, and a mechanism which responds to the addition of a new component by searching the database and constructing a specific control interface. The specific control interface addresses all the capabilities and functions of the new component without the need for manual input of functions and capabilities by the user.




A method of operating the computer-based system is also embodied by the present invention. The method comprises providing a database listing functions of one or more peripheral devices and corresponding graphical-user-interface elements (objects) for accessing the functions, searching the database for a particular media device, and displaying a graphical user interface for the particular media device based on functions and corresponding graphical user interface elements listed in the database.




In a further embodiment of the present invention, the interconnection of various components is determined, and tunable devices connected to the system are identified by the type of connection to a further channel receiving component they employ, namely “off-air antenna,” “cable,” “satellite,” or “no antenna.” “No antenna” devices may include those directly hooked to the computer as described above, such as DVD-ROM, equalizers, amplifiers, and the like, which have functionality but not necessarily channels. A channel map for the various tunable devices is generated (or supplied in a database) and is used to identify the channels available for each device. Each tunable device propagates its available channels to the computer system (software) and each interconnecting device supplements the information appending control information and its own channel map information. The end result is a computer based model representing the components attached to the home entertainment system, and the channels they are capable of receiving, their available channels.




Further embodiments of the present invention include a database containing information concerning not only the channel map of connected devices, but also the functionality of devices and non-device specific user interface protocols from a database containing functionality information and user interface protocols. A user interface assembly program or module creates a computer based set of objects in a GUI allowing control of the devices attached to the system. Instead of requiring the user to generate manually a list of the available functions, capabilities, and available channels of the devices attached to the system, this embodiment uses a series of user interface elements or protocols which can be retrieved from the database when it has been successfully queried as to the functionality of the attached components.




A further embodiment of the present invention comprises a computer system having a first device database, and a software program having database lookup capabilities for all devices from a device database, and a second database for the retrieval not only of available channels for the device, but also the elements or user interface protocols for the generation of a computer based system of objects displayable on a computer screen allowing for computer control of all aspects of the computer based home entertainment system.




Other embodiments and advantages of the invention will become apparent after considering the accompanying drawings and the following detailed description.

. Monitor


110


, the heart of the system from a user perspective, displays video programming from peripheral devices


120


or personal computer


130


.




Peripheral device


120


receives audio, video or digital data signals via direct connection or wireless coupling to a multi-channel programming source. Examples of multi-channel programming sources include satellite television and radio broadcasts, cable television transmissions, traditional television transmissions, radio broadcasts, and the like. A plurality of peripheral devices may be connected to or in communication with a variety of programming sources by a variety of configurations. Such configurations include antenna, cable, satellite, and no-antenna.




Personal computer


130


, operatively coupled to monitor


110


and device


120


, includes by way of example but not limitation a processor


132


, a local memory


134


, a mass-data-storage device


136


, a modem


138


and a set of user interface devices including, for example, a keyboard


140


and a mouse or other pointing device


142


all of which support user interaction with a graphical user interface or operating system, such as a version of Microsoft Windows.




Mass data storage device


136


is shown in greater detail in

FIG. 1



a.


Mass data storage device


136


preferably includes a hard drive which stores software including various user programs, an operating system, communications software, and the like. It should be understood that the configuration of the system


100


, including computer


110


and mass storage


136


may be changed to include additional components, or to delete components, without deviating from the scope of the invention. Such alternate configurations are well known in the art.




Additionally, storage device


136


stores a comprehensive peripheral device functionality and user interface element database


144


. Database


144


preferably contains comprehensive information pertaining to the functionality of peripheral devices, including brands, models, and types. Database


144


further preferably contains a comprehensive set of user interface build elements, also called protocols, designed to provide the blocks for building graphical user interfaces modeling the functions and features of peripheral devices


120


connected to computer


130


and system


100


. User interface build elements are designed to replicate the various functions and features of peripheral devices


120


in a graphical user interface environment. The user interface elements described are treated as individual objects within the software architecture, allowing more flexibility in design and the capability of introducing the entire system to other computing platforms.




Database


144


further contains channel map information pertaining to available channels from various sources, including as discussed above cable, satellite, and antenna. Database


144


may be split into separate databases, such as a device functionality database, a user interface element database, and a channel map database, without departing from the scope of the invention.




Storage device


136


stores an interface-assembly program or software module


146


. Graphical user interface assembly program


146


contains a set of machine readable instructions for communicating with the various databases


144


, and, through computer processor and memory, the connected peripheral devices


120


, and thereafter to construct a graphical user interface


148


for display on monitor


110


. The software module


146


of the present invention may be implemented by computer programs of machine-executable instructions written in any number of suitable languages and stored on machine or computer readable media such as disk, diskette, RAM, ROM, or other device commonly included in a personal computer such as computer


130


.




For example, the database may contain a peripheral device description for an attached peripheral device such as a VCR. Typical functionality information contained in the database includes the following functions: play, stop, pause, fast forward, rewind, frame advance, frame speed, tape speed, and menus. Thus, in response to detecting that the VCR is connected to one of the system input ports of computer


130


, system


100


would determine which graphical user interface objects, or elements, are available to control the identified functions of the VCR. In other words, the system


100


searches an interface object database


144


for elements that correspond to each identified function of the VCR, and returns links to the objects. In this example, searching the resource database yields the following interface objects: play, stop, pause, fast-forward, rewind, frame-advance, frame-speed slider, tape-speed selector, and set-up menu items. The interface assembly program


146


then assembles these objects into a specific graphical user interface for the VCR. This graphical user interface


148


is displayed on monitor


110


for control of the connected VCR from the screen of monitor


110


.




Construction of the graphical user interface of the present invention is accomplished without the requirement for manual user input. The functions of preferably the vast majority of peripheral devices available for connection to a computer based home entertainment system such as system


100


are contained in the database


144


. Database


144


, or individual databases containing portions of the database


144


, may be easily updated and replaced entirely. The present invention is therefore not limited to the “least common denominator,” instead generating comprehensive graphical user interface controls for all of the functionality of the connected peripheral devices.




Graphical user interface assembly program


146


may also contain instructions for communication with various peripheral devices


120


to determine the functionality of the peripheral devices if the device functionality is not available in the database


144


. Once functionality is determined, the software program retrieves the appropriate user interface elements from database


144


for construction of the graphical user interface


148


.




Referring now to

FIG. 2

, a method embodiment


200


for generating a computer-based model of connected peripheral devices in a home entertainment system comprises identifying a peripheral device connected to the computer in block


202


, and querying a database regarding functionality of the identified device in block


204


. If the device is in the database, device specific user interface elements for the specific device are retrieved in block


206


. If the device is similar to a device in the database, in that the functions are nearly the same, device specific user interface elements are retrieved in block


206


as well. If the device is not in the database, generic user interface elements are retrieved in block


208


. Alternatively, the device not in the database may be queried to determine specific functionality in block


210


and user interface elements retrieved in block


212


. Once user interface elements have been retrieved in blocks


206


,

302


, searching the database for a particular peripheral device which is connected to the computer in block


304


, and displaying a graphical user interface for the particular media device based on functions and corresponding graphical user interface elements listed in the database in block


306


.




A number of peripheral devices


120


may be attached to the system in known fashion. Such attachments or connections include but are not limited to wire connections directly to the audio/video input of the computer-based controller, or interconnected in a chain-like fashion between components. Each peripheral device is therefore connected to or interconnected with the system, but need not be directly connected to the internal tuner connected to the audio/video input of the system.




Each peripheral device has its own connection or link to a source of programming or channels available for its use. For example, the devices may receive programming information from an off-air antenna, a cable line, a satellite link, or the like. In addition, certain peripheral devices might not be attached to any antenna at all. These no antenna devices include DVD-ROM, CD-ROM, laserdisc, equalizers, amplifiers, and the like.




Each peripheral device has its own set of channels or signals which it is capable of receiving. The channels a device is capable of receiving are referred to as its available channels. Each device further has specific functionality which determine how the device is tuned to a particular available channel, as well as control information.




Another embodiment of the present invention gathers from each peripheral device


120


attached to or interconnected with a system the type of connection the device has to its programming source, that is antenna, cable, satellite, or no antenna. Also, the embodiment gathers from each device a list of its available channels. Tuning information, specifically the operations or instructions required to tune each various peripheral device to a specific available channel, is also gathered. From the gathered information, a computer based channel map may be generated for the entire system.




Each peripheral device provides to the channel map its functionality, tuning information, connection information, and available channels. A computer based model of the entire system us generated from the information received from the attached or interconnected devices.

404


. The devices propagate their channel information through the model in block


406


. Control information and channel map information for the peripheral devices is appended to the model in block


408


. The generated computer based model provides a way to operate the functionality of each peripheral device from a computer based user interface. The computer model generated may be stored in a data structure in machine readable format in the computer system.

512


, DVD, modem, and the like. The processor unit of such a computer typically includes a microprocessor, memory (RAM and ROM), and other peripheral circuitry, not shown.




The computer programs run on the central processing unit


506


out of main memory, and may be transferred to main memory from permanent storage via disk drive


510


or CD-ROM


512


when stored on removable media or via a network connection or modem connection when stored outside of the personal computer, or via other types of computer or machine readable medium from which it can be read and utilized. The computer programs comprise multiple modules or objects to perform the methods

, or


400


, or the functions of the modules in apparatus


100


. The type of computer programming languages used to write the code may vary between procedural code type languages to object oriented languages. The files or objects need not have a one to one correspondence to the modules or method steps described depending on the desires of the programmer. Further, the method and apparatus may comprise combinations of software, hardware and firmware as is well known to those skilled in the art.




An embodiment of a computer system


500


for creating graphical user interface objects includes a device database


514


containing functionality information pertaining to peripheral devices, a resource database
