This is a continuation of application Ser. No. 08/162,500, filed Dec. 3, 1993 now U.S. Pat. No. 5,479,302.

BACKGROUND OF THE INVENTION

1. Field of The Invention

This invention pertains to videocassette recorder (“VCR”) systems, and more particularly to a single deck dual tape path videocassette recorder (“VCR”) system that enables utilization of two tape paths for selective simultaneous functions. The present invention provides an integrated (single chassis, single videocassette platform, single tuner, single power supply, single control set,) dual tape path VCR system usable with a fully featured television set or with one or more components of a video system (e.g. antenna, monitor, tuner) enabling recording of an off-the-air broadcast or a cable transmitted signal to a videocassette tape from one tape path of the dual tape path VCR system, while allowing near simultaneous playback of the same videocassette tape from the other tape path to an associated television set or monitor.

2. Background Information

Video cassette recorders (VCR) are currently in widespread use and have several operable modes. In a record mode, the VCR is operable for recording a television broadcast on a suitable videocassette tape. In a playback mode, the VCR is operable for transmitting a previously recorded television broadcast to a conventional television receiver where it may be played back at the convenience of the viewer. The use of VCRs has therefore provided a means for viewers of television broadcasts to control their viewing habits by, for example, recording a television program at the time of its broadcast and then viewing the recorded program at some point in time after the broadcast.

Viewing a recorded program through the VCR enables the viewer to take full advantage of many useful VCR functions, including pause, fast-forward, and rewind. The pause function enables the user to stop the prerecorded program and resume viewing the program at any time. The viewer can rewind selective scenes and, more importantly, fast-forward through any unwanted commercials.

Several prior inventions have provided an additional degree of viewer convenience over and above the standard VCR functions described above. One such class of inventions automatically eliminates commercials from the recorded program. Most of these systems (“commercial killers”) focus on the detection of certain signals, fades, or pauses in the original broadcast. As a result the recorded programs can be subsequently viewed on playback without commercials.

Other prior disclosures describe means for enabling the viewer to record two broadcast programs simultaneously through the use of dual recording decks. One advantage of such a system is that the viewer can record two programs at the same time while viewing a third program on a TV monitor. The circuitry for dual simultaneous recording and playing was disclosed in detail in U.S. Pat. No. 4,124,807, issued Jun. 23, 1992, to Dunlap et al. The Dunlap invention enables simultaneous recording/playback onto two separate video cassette tapes.

Setting or programming the recording time for a broadcast has also been made easy with the invention of user friendly on-screen commands and with the new “VCR Plus” codes. In many cases the user has only to input a few numbers to program the VCR. Many other inventions have also enhanced the overall quality and usefulness of the standard VCR.

Viewing recorded programs through a VCR enables the user to have near total viewing control of the transmitted program. Even though the viewing of recorded programs through a VCR has so many advantages, it still appears that most people watch the majority of their broadcast programs as the program is being transmitted. Why, for example, should a viewer sit through lengthy commercials when they can record a program and then subsequently watch the program on playback without commercials? One major reason, and the biggest disadvantage of prior art, is the time it takes to record and subsequently playback the desired program. There is no system described that allows the user to playback a program during recording. If the viewer wants to utilize the VCR playback functions while viewing a recorded program, the viewer must wait until the program has finished and the VCR has stopped recording. Only then can the recorded program be played back.

Applicant's invention addresses the need for a VCR system that provides the user with near simultaneous recording and playback of a broadcast or cable communicated television signal in addition to all of the standard controls of existing videotape systems.

SUMMARY OF THE INVENTION

The present invention is a videocassette recorder/playback system enabling near simultaneous recording and playback of a broadcast or cable communicated television signal. The system consists of standard elements which allow the receipt of a videocassette, the extracting and return of video tape from and to the videocassette, and the recording of a broadcast or cable communicated signal. The system, however, also consists of two tape path assemblies and a videotape compartment consisting of a tape feed channel, a storage assembly, and a vacuum system. The first tape path is for recording a television signal or for playing a recorded television signal and the second tape path is for playback of a recorded television signal from videotape extracted from the storage assembly or for recording a television signal on videotape extracted from the storage assembly.

The system of the present invention minimizes the time delay between recording a program and subsequently playing back the recorded program, allowing near simultaneous playback of a transmitting broadcast program. The unique simultaneous record/playback feature of the present invention allows the viewer to take full advantage of the many useful VCR functions without interrupting the recording of the program.

It is, therefore, an object of the present invention to overcome the prior-art drawbacks associated with standard recording and subsequent playback techniques and apparatus. The system of the present invention minimizes the time delay between recording a broadcast program and subsequent playback of the recorded program. The present invention allows the viewer near simultaneous record and playback of a broadcast program as it is transmitting.

It is also an object of Applicant's invention to provide a VCR system which, by incorporating dual tape paths and a storage assembly permits the simultaneous recording of two programs on a single videocassette.

Another object of Applicant's invention is to provide an enhanced videocassette recorder (VCR) system which, by incorporating a variety of record, playback, and videotape storage features, allows commercial free viewing as well as replay viewing during simultaneous recording and playback. Every program can now be viewed commercial free. The viewer may fastforward through an unwanted commercials. Sporting events may be viewed in a whole new manner with the viewer having total control over the creation and viewing of instant replays. The user, for example, may rewind, pause, or slow motion his favorite football play without interrupting the recording of the broadcasting program.

In addition, the present invention is an ideal “safety net” for viewing all programs. If the present invention is consistently used, the viewer will never miss parts of a broadcast program due to personal interruptions. If the viewer is interrupted during the program or needs to take a break from the program and cannot wait until a commercial appears, the viewer can, through Applicant's invention, simply hit the pause button, attend to the interruption and then begin viewing the program again without interrupting the recording and without missing any part of the transmitting broadcast program. The present invention enables the viewer near instant playback of the recording broadcast program through the VCR.

It is a further object of Applicant's invention to provide a low cost, mass-market single deck, duel taping system videocassette recorder unit which is easy to understand and use, adaptable with current and future circuitry, reliable and multi-functional, with a range of useful operations available for entertainment, educational and/or business purposes. The system of the present invention can be adapted to most VCRs manufactured today, as well as new developments currently in progress with minimal modifications and cost to the manufacturers. Because of the flexibility of the storage assembly's shape, the present invention can be custom designed to fit into almost any type of VCR system. Most of the standard VCR parts will not require modification thus minimizing manufacturing costs.

Further objects and advantages of the present invention will become apparent from the following description in light of the attached drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawings and particularly to FIG. 1, the housing (7) and front panel (8) of a single deck dual tape path videocassette system (9) providing broadcast recording and playback control and utilizing playback features hereinafter described is shown. System (9) is contained within a single housing (7) and, as will be described, includes a dual tape path arrangement for receiving a conventional videocassette tape therein.

Tape path-A (10) and tape path-B (11) are connected to built in storage assembly (18) and single access port (16). “Tape path” as used herein comprises hubs, for engaging drive wheels of the videocassette, motor means for driving one or both hubs, motor controls and electromagnetic, electrostatic, and/or optical transducer heads for exchange of control signals and information with the videotape medium of the videocassette. Built-in storage assembly (18) and its connection to tape path-A (10) and tape path-B (11) are described in conjunction with FIG. 4. Control panel (21) is used to control tape path-A (10), specifically for recording/playing-back a videocassette tape located-in access port (16). Thus, control panel (21) enables the user of the present invention to rewind, fast forward, stop, pause, play, record, and eject a videocassette tape located in access port (16). In turn, control panel (23) is used to control tape path-B (11), specifically for recording/playing-back video tape located in storage assembly (1). Likewise, control panel (23) enables the user of the present invention to rewind, fast forward, stop, pause, play and record video tape located in storage assembly (18).

Control panels (21) and (23) may be operated simultaneously. LCD time display (26) and optical sensors (not shown) in conjunction with a standard microprocessor well known in the art determine which functions on control panel (21) can operate simultaneously with the functions on control panel (23) by keeping track of the location of the video tape in path-A (10) and path-B (11) and the amount of tape, if any, in storage assembly (18). For example, the fast forward, playback and record functions of control panel (23) will only operate if there is video tape in storage assembly (18) and will automatically stop operating once storage assembly (18) is empty.

Input selection switches (20) and (22) are located on the front of housing (7) below port (16). Input selection switch (20) is provided for selecting the input signal line from which a program will be recorded onto a blank videocassette tape that has been inserted into access port (16). Input selection switch (22) is provided for selecting the input signal line from which a program will be recorded onto video tape in storage assembly (18). Output selection switch (24) is located on the front of housing (7) below and to the right of port (16) and, as will be described, selects a signal line which will be connected to the video monitor (not shown) for viewing. Input selection switches (20) and (22), output selection switch (24), and other VCR functions, i.e., play, record, rewind, fast forward, could also be operated from a remote control device (not shown).

Referring now to FIG. 2, the single deck dual tape path videocassette system (9) (shown in FIG. 1) according to the preferred embodiment therefor is schematically illustrated and in this connection it is understood that the electrical components, as illustrated in block diagram form, are composed of conventional circuitry well known in the art except as otherwise specified herein. As shown in FIG. 2, electrical inputs into system (9) (shown in FIG. 1) include a TV antenna signal or cable TV input (29) that is directed through TV tuner (28), video input (31) that is directed through isolation amplifier (30), and camera video input (32). Port (16) provides video cassette tape access to path-A (10) and path-B (11), both of which have VCR play and record capabilities. Switch positions 1-3 of selector switch (20) direct the signals from inputs (29), (31), and (32) into VCR tape path-A (10). Therefore, position #1 on selector switch (20) directs the signal from the TV tuner (28) into path-A (10). Position #2 on switch (20) directs the signal from isolation amplifier (30) into path-A (10), and switch position #3 directs the signal from camera video (32) into path-A (10). Selector switch (22) and switch positions 1-3 therefor are disposed in parallel relation with respect to switch (20) and the switch positions thereof and direct the signals from inputs (29), (31), and (32) into VCR tape path-B (11). Thus, the input signal from TV tuner (28) is directed to path-B (11) through switch position #1 on selection switch (22), while the signal from isolation amplifier (30) is directed to path-B (11) through switch position #2 on selection switch (22), and switch position #3 on selection switch (22) directs the signal from camera video (32) to path-B (11). In addition, the output of tape path-A (10) is directed to path-B (11) through witch position #4 on selection switch (22). Thus, a broadcast program recorded through path-A (10) can be played back, before the completion of the transmitting broadcast, through path-B (11) by moving selection switch (22) to position #4.

The input signals may also be directed to TV monitor (not shown) for video display thereon. For this purpose, output selection switch (24) through the switch positions 1-7 thereof is moved to the appropriate position for selecting the desired signal among the seven outputs for connection to the TV monitor. As shown in FIG. 2, TV tuner (28) is connected directly to the TV monitor through switch position #1 on selection switch (24). A video line through isolation amplifier (30) is also connected to the TV monitor through switch position #2 of selection switch (24). If the videocassette tape located in access port (16) has been prerecorded, and it is desired to view this tape information on the TV monitor, selection switch (24) is moved to switch position #6. If the video tape located in storage assembly (18) (shown in FIG. 1) has been prerecorded, and it is desired to view this tape information on the TV monitor, selection switch (24) is moved to switch position #7.

The combination of input selection switches (20) and (22) and output selection switch (24) enables a versatility of operations that was not available in the previously known single and dual deck VCR systems of the prior art. The operations available through the combinations of input selection switches (20) and (22) and by output selection switch (24) are illustrated below:

By utilizing the single deck dual tape path VCR system of the present invention, it is now possible by use of selection switches (20) and (22) to record a TV program through TV tuner (28) that is connected to switch position #1 of selection switch (20), while at the same time playing back the recording program on a TV monitor from tape path-B (11) through switch position #4 of selection switch (22) by activating record function on control panel (21) (shown in FIG. 1) and the play function on control panel (23) (shown in FIG. 1) and movement of output switch (24) to position #7.

Referring once again to FIG. 1, the system (9) can also be used for simultaneously recording from a broadcast or auxiliary input to the video tapes in both tape path-A (10) and tape path-B (11). This is accomplished by feeding enough blank tape into storage assembly (18) while maintaining adequate blank tape on the videocassette for the recording of the two desired programs.

Referring now to FIG. 3, a typical prior art path taken by tape (37) as it moves from supply reel table assembly (36) located in video cassette (34) to take-up reel table assembly (100) located in video cassette (34) is illustrated. Tape (37) is extracted from cassette (34) and passes supply tension regulator arm assembly (38) and (40). Supply tension regulator arm assembly (38) and (40) changes the forward direction of tape (37) toward drum (42). Tape (37) then passes full-width erase head (44). Tape (37) runs approximately 180 degrees around drum (42) where rotary video heads (not shown) make contact with it during record and playback. Tape (37), having passed drum (42), passes ACE (Audio, CTL and Erase) head (50). Tape (37) is squeezed between capstan assembly (52) and pinch roller assembly (54). Capstan assembly (52) rotates at a constant speed, advancing tape (37) at a fixed rate into take-up reel (100) located in cassette (34). The present invention utilizes this basic standard tape path arrangement with minor modifications when combining tape path-A (10) (shown in FIG. 1) with a second tape path, tape path-B (11) (shown in FIG. 1).

FIG. 4 is a diagrammatic plan view of Applicant's invention. It is understood that the mechanical components illustrated in FIG. 4 and in FIG. 5 are composed of conventional mechanical components well known in the art except as otherwise specified herein. It is further understood that the electrical components in FIGS. 4 and 5 are composed of conventional circuitry well known in the art except as otherwise specified herein. According to the present invention, tape path-A (10) and tape path-B (11) are identical to one another, except where noted, and are connected by means of built-in storage assembly device (18), which will be described in detail later.

Tape path-A (10), tape path-B (11) and storage assembly (18) are contained in single housing VCR unit (7) (shown in FIG. 1). Video tape (37), by way of tape path-A (10), moves from supply reel table assembly (36) located in video cassette (34) to storage assembly (18).

Tape (37) is extracted out of cassette (34) and passes supply tension regulator arm assembly (38) and (40) of tape path-A (10). Supply tension regulator arm assembly (38) and (40) changes the forward direction of tape (37) toward drum (42). Tape (37) then passes full-width erase head (44). Tape (37) runs approximately 180 degrees around drum (42) where rotary video heads (not shown) make contact with it during record and playback. Tape (37), having passed drum (42), passes ACE (Audio, CTL and Erase) head (50). Tape (37) is squeezed between capstan assembly (54) and pinch roller assembly (52). Capstan assembly (54) rotates at a constant speed, advancing tape (37) at a fixed rate through Path-A (10) and into storage assembly (18). If desired, a standard prior art tape path could be followed, tape (37) bypassing storage assembly (18) being directly fed into take-up reel (100) located in cassette (34) by way of capstan assembly (92) and pinch roller assembly (94).

Video tape (37) by way of tape path-B (11) moves from storage assembly (18) to take-up reel table assembly (100) located in videocassette (34). Specifically, tape (37) is extracted from storage assembly (18), and is passed between capstan assembly (77) and pinch roller (76) to supply tension regulator arm assembly (78) and (80) of tape path-B (11). Supply tension regulator arm assembly (78) and (80) change the forward direction of tape (37) toward drum (82). Tape (37) then passes full-width erase head (84). Tape (37) runs approximately 180 degrees around drum (82) where rotary video heads (not shown) make contact with it during record and playback. Tape (37), having passed drum (82), passes ACE (Audio, CTL and Erase) head (90). Tape (37) is squeezed between capstan assembly (92) and pinch roller assembly (94). Capstan assembly (92) rotates at a constant speed, advancing tape (37) at a fixed rate out of storage assembly (18), through path-B (11), and into take-up reel (100) located in cassette (34).

Capstan assembly (54) and pinch roller (52) feed tape (37) through tape path-A (10) into and out of storage assembly (18) and cassette (34), Capstan assembly (77) and pinch roller (76) draw tape (37) through path-B (11), into storage assembly (18) and cassette (34), while capstan assembly (92) and pinch roller (94) draw tape (37) through path-B (11) out of storage assembly (18) and into cassette (34). Capstan assemblies (54) and (92) direct tape (37) through a tape path during record/playback at a constant fixed speed thus enabling the recording of a program through Path-A (10) and the play back of the same recorded program through Path-B (11).

Since the standard tape path is only slightly modified, prior art threading techniques can be utilized in the present invention and therefore is not described in detail herein. The following patents are illustrative of tape threading and guiding arrangements that could be adapted to the present invention: U.S. Pat. Nos. 5,164,868, issued Nov. 17, 1992, to Mosher et al.; and 5,144,505, issued Sep. 1, 1992, to Kaneko et al.

FIG. 5 is a diagrammatic plan view of the preferred embodiment of the present invention. Storage assembly (18) consists of floor (55), ceiling (not shown), and surrounding walls (57), (58), (59), (60), (61), (62), (63), and (64). The height of storage assembly (18), the distance between floor (55) and the ceiling of storage assembly (18), is slightly greater than the width of tape (37) preventing tape damage and tape entanglement. The size of storage assembly (18) enables two hours of video tape (recorded at EP speed) to be stored. When digital videocassette recording becomes standardized and available to the general public, the size of storage assembly (18) could be reduced in half since digital videocassette tape will be half the length and width as standard videocassette tape.

Once tape (37) is fed in storage assembly (18), by capstan assembly (54) and/or capstan assembly (77), optical sensors (not shown) operating in conjunction with a microprocessor (51) activate vacuum system (56). Vacuum systems such as that utilized in Applicant's invention are well known in the art and are thus not disclosed in detail here.

Vacuum system (56) draws air through perforated walls (61a), (62a), (63a), and (64a) causing tape (37) to be drawn against perforated walls (61a), (62a), (63a), and (64a). The perforations in walls (61a), (62a), (63a), and (64a) are a fraction above and below the edges of the width of tape (37), thus preventing tape (37) from blocking vacuum system (56). As tape (37) forms slack in storage assembly (18), vacuum system (56) draws tape (37), in a controlled random manner, towards walls (61a), (62a), (63a), and (64a) thus effectively utilizing storage space. Roller guides (66), (68), (71) and (73) constantly rotate in a clockwise direction, while roller guides (67), (69), (70), and (72) constantly rotate in a counter clockwise direction, preventing tape (37) from prematurely storing between walls (57), (58), (59), and (60). Vacuum system (56) is deactivated by means of sensors (not shown) operating in conjunction with a microprocessor once all of tape (37) is extracted from storage assembly (18).

It will now be apparent to those skilled in the art that other embodiments, improvements, details, and uses can be made consistent with the letter and spirit of the foregoing disclosure and within the scope of this patent, which is limited only by the following claims, construed in accordance with the patent law, including the doctrine of equivalents.
