II. Description of the Related Art
Historically, the recording and playback of sound and video has involved dumb media and smart machines. Vinyl records are simply mechanical grooves from which a phonograph could interpret and produce sound and music. Audio tapes are recorded using a recording head that magnetizes the tape in a pattern that is reflective of the sound to be recorded. During playback, the tape moves past a playback head. The magnetic fields from the magnetized region of the tape sweep past the playback head and cause fluctuating electric currents to flow through the head. The changing magnetic field produces an electric field in the head which is amplified and used to operate the speakers to produce the recorded sound. Thus, the magnetized regions of the tape provide the same function as the mechanical grooves of a phonograph record. Video tapes work in a similar fashion with recording heads to create magnetic patterns on the tape and playback heads to read those magnetic patterns.
Even in the digital age, compact discs are dumb. A recording device creates lands and pits representing ones and zeroes on the disc. The compact disc player then lo reads the lands and pits and processes them to play back sound and video. Whether it is a phonograph, an audio tape player, a video tape player or even a CD player, all of the logic and intelligence is located in the player rather than in the media used with the player.
Various systematic disadvantages arise from the approach of using dumb media and smart players. For example, it is almost impossible to change the way the user interacts with the media to any significant degree. Even with audio compact discs, the media is so limited that the only option really available to the user is to change the order in which the songs recorded on the media are played. The creator of content for media such as phonograph records, audio tapes, video tapes and even compact discs are severely restricted since they are only able to use functions of the player in only the prescribed manner in developing content.
Over the past 20 years, video cassette recorders, compact disc players, televisions, stereo receivers, audio tape players and the like have been sold with a user interface on the machine itself, as well as a remote control which provides a second user interface. Until very recently, each remote control was designed specifically for use with a particular type and model of device. More recently, remote control function has become more standardized. As such, universal and teachable remote controls are now offered for sale which interface with multiple consumer electronic hardware products in the home.
Digital versatile disc (DVD) represents a sea change. DVD players are smarter than their predecessors. More importantly, DVD media (the authored discs) are very smart. DVD video players support a wide range of digital formats and allow many avenues of access through a standardized set of commands. The authors of DVD media can take advantage of these capabilities to create a variety of products, all of which can be played on the DVD player. The remote control of the DVD player can be used to access the various features of the DVD media. Such access can be through numbers on the remote control's keypad, the remote control's arrows that move a cursor around a menu, or through the remote control's direct input keys. As such, a standard DVD remote control is the most complex consumer interface yet produced.
The DVD's specification universally adopted by most manufacturers assigns key functions to each key or button of the remote control However, a DVD disc can be authored to use that function or key in a completely different manner than that intended by the specification. For example, a DVD disc could be authored so that the viewer has to enter an entire numeric code to gain access to the disc or certain sections of the program. Also, the DVD disc can be authored to perform entirely different functions in response to signals created by the user pressing the direct input keys than those contemplated by the standard. Such capabilities represent opportunities heretofore unknown in the consumer electronic industry for media authors.
The present invention takes advantage of the capabilities of DVD players and expands the usefulness of DVD media by providing a totally unique remote control having interchangeable faceplates, each of which is matched to one or more DVD disks. Specifically, icons on the faceplate are matched to icons in program menus displayed on television when the DVD disk is played in the DVD player. The viewer can press the matching icon on the remote control to navigate and use the program.
This invention has a variety of applications. First, the present invention can be used in international or multi-lingual environments. Internationally recognizable icons can be incorporated into the program and a matching faceplate for a remote control so that language barriers do not preclude one from using the program.
Second, the present invention has broad application for media designed for young children who can learn, but have not yet learned to read. Programs designed for them can include icons that match those on the faceplate. The icons can, for example, be cartoon characters, shapes, colors, numbers or letters. The program can be a learning tool that captures the child's attention and the remote control equipped with the title-specific faceplate can easily be used by the child to direct the program. The child does not become frustrated by the user interface because the matching icons of the program and the faceplate are geared to his or her level. Also, depending upon the program itself, the child receives constant feedback. Children's programs on DVD can be in the form of either entertainment or educational media.
Third, the present invention permits DVD media to be combined with books, such as children's books, to provide an interactive multimedia experience. For example, a book can be packaged with a DVD media capable of being played on any DVD player. Switches are built into the book beneath pictures or other icons printed on the pages of the book. Thus, the pages of the book become the faceplate of the remote control for the DVD player. As the switches are actuated, signals are sent to the DVD player which control the operation of the DVD player based upon software instructions coded on the DVD media.
Fourth, the present application has application as a low cost training aid. For example, the DVD player and television set, in conjunction with the program stored on the DVD media, can function as a simulator for any of a variety of pieces of equipment such as hazardous material disposal equipment, medical equipment, manufacturing equipment or the like. The faceplate for the remote control can be designed to match the controls for the piece of equipment, the operation of which is simulated by the program recorded on the DVD disc. A specific advantage provided by applicant's invention is that any of a variety of pieces of equipment can be the subject of the simulation using the same television, player and remote control. All the creator of the simulation needs to provide is the program on a DVD disk and a matching faceplate.
The type and number of applications of the present invention can be expanded further through use of the programmable memory registers of a standard DVD video player. Such players have sixteen 32 kilobyte programmable memory registers. These registers can be used for a variety of functions such as tracking scores in a DVD-based game, monitoring progress through a DVD-based lesson, or even tailoring the program recorded on the DVD based upon the ability level of a user.
A greater understanding of the present invention and the advantages it affords can be derived from the following detailed description of the invention in light of the drawings which form a part of this disclosure.
As shown in
As indicated above, the remote control 103 of the present invention consists of two major separate components--a base unit 104 and at least one interchangeable faceplate 105. The construction of the base unit 104 is shown in
As shown in
Control chips for DVD remotes include certain standard pins. These pins are used to create the electrical paths 1-30 from the female connector 114 to the control chip 110. The signals received by the control chip 110 via each of the pins are intended to cause the control chip 110 to send specific signals to the player 102 via the IR lamp 116. The design of the female connector 114 of the present invention is such that it can be quickly and easily mated with a male connector 118 of any of a number of interchangeable, title-specific faceplates 105. In addition to the male connector 118, the faceplates 105 each have at least one switch 120. Each switch is colored, labeled or shaped to correspond to the icons displayed by the program with which the particular faceplate 105 is associated. Each switch 120 is wired to the male connector 118 such that when the switch is actuated, a signal indicative of the switch actuation can be processed by the controller chip 110. In response to this signal, the controller chip 110 causes the IR lamp 116 to illuminate in a given pattern to send a message indicative of the specific switch closure to a receiver in the player 102.
The various switches 120 of the faceplate 105 are each electrically connected to the male connector 118 in such a way that when the male connector 118 and female connector 114 are connected and a switch is actuated, the control chip 110 knows which switch 120 has been actuated. The control chip 110 responds to the closure of different switches 120 by causing the IR lamp 116 to send a different signal to the player 102.
In
The advantages of the present invention from a user standpoint may be better understood with reference to
Although not shown, other faceplates having buttons of different shapes and colors that can be wired to a male connector 118 in a predefined manner so the controller can send the desired standard signal to the DVD player upon actuation of each button.
From the foregoing, it should be clear that the faceplate 5 can include one to twenty-nine switch buttons. More, of course, can be added if a control chip other than a standard DVD chip is used in the remote and if the player can respond to a larger number of different signals. The switch buttons can be any shape, color or size. The switch buttons can be labeled with text or other symbols. What is important is that the switch buttons match (or at least correspond to) icons displayed on the television 1 or monitor attached to DVD player 2. The user simply presses the switch button that matches an icon on the screen with a menu selection from a menu of options shown on the screen to signal the program. The icons can be any shape, color, size, character, number, letter, symbol or group thereof. The present invention is highly useful in creating a simple user interface such that selection options shown on the screen of the television or other type of monitor match the switch buttons on the remote control.
A key to preferred embodiments that include faceplates is the connection between the male connector of the faceplate with the female connector of the base. This can be accomplished in any of a variety of ways. The base unit and faceplate can be designed to snap together. These components can be built to incorporate interlocking rails or grooves. Even fabric hook and loop-type fasteners could be used. An extension cable can be used to electrically connect the male and female connectors, particularly if the user wants to be able to manipulate the switches from a position out of a direct line of sight from the DVD player 102. Such an extension cable permits the faceplate 105 and the base unit 104 to function together even if the faceplate 105 is positioned remotely from the base unit 104.
Further, while specific connectors are shown in the drawings, other connectors would be used. Also, reversing the connectors so the male connector is on the base and the female connector is on the faceplate is well within the scope of this invention. Whatever connectors and arrangement of connectors are used, there must be an output on the faceplate coupled to an input on the base unit such that the depression of any switch on the faceplate will cause the remote control 103 to issue a predetermined command to the player 102.
Further, while specific embodiments of a remote control base unit 104 and interchangeable faceplates 105 have been shown and described in
The generic “remote” 104 of
Still further implementations of a remote control having interchangeable user interface components are shown in
The embodiment of
Finally, the various faceplates shown in the drawings are just some examples of suitable faceplates. Virtually any arrangement, shape, size, color and labeling of the switch buttons can be used. The number of switches can range from one to twenty-nine or even higher. This is all dependent on the design of the program and creativity of the developer in developing a user interface that takes advantage of the present invention.
