`Description
`
`The present invention generally relates to light-
`weight. portable computers and. more particularly, to an
`entertainment system which is fully integrated into the
`portable computer and supported by software running
`on the computer.

`
`BACKGROUP DESCRIPTION
`
`Small portable computers. sometimes referred to
`as notebook computers. are commonly used in a variety
`of demanding environments for productivity and con-
`venience. The progress of computer technology has
`made notebook computers small. yet powerful enough
`to use in many different physical environments such as.
`for example. at home, in vehicles. or even outdoors.
`Often. notebook computers are carried by profes-
`sional or business users when they travel. During such
`occasions, particularly in airports. users have long peri-
`ods when they are simply passing time. Hence. it would
`be advantageous to integrate an entertainment system
`into a notebook computer to thereby allow a user; wait
`ing to board an airplane. to watch television. watch a
`movie. or listen to music.
`in the past. devices have been developed to occupy
`and entertain travelers. For example. U.S. Patent
`4.521.021 to Dixon shows a video game table tor air-
`planes in which a video console attaches to the seat
`backs to tom-I a table for playing video games lrorn video
`cartridges. While entertaining. this approach is not port-
`able and limited to playing video games in passenger
`vehicles so equipped.
`US. Patent 4.865.515 to Tagawa at at. shows a
`passenger service and entertainment system ‘or cup-
`plying frequency-multiplexed video. audio. and televi-
`sion game software signals to users seats. The system
`consists ota central transmitting apparatus and a plural-
`ity of cathode ray tube (CRT) or liquid crystal display
`(LCD) terminal units mounted in seats. such as. for
`example. airplane seats. stadium seats, or theater
`seats. The central transmitting apparatus of the system
`distributes video signals. audio signals, and television
`game software signals to the terminal units through tre-
`quency-rnultiplexing. Both the central transmitting appa-
`ratus and each of the terminals are permanently located
`at a tlxed location.
`Similarly. the marriage of desktop computers and
`television has been experimented with in the past with
`very limited applications. For eirarnple. US. Patent
`5.3?4.952 to Flohr shows a video conferencing system
`lor fixed location computer workstations that operates
`on local area networks to exchange data and to transmit
`cable television signals via a coaxial cable television
`wire.
`Likewise. U.S. Patents 5.359.357 to Stockhill.
`5.249.164 to K02. and 5.283.819 to Glick et al. show
`personal desk-top cornputers with added television
`capabilities. An obvious drawback to all of these devices
`
`is that desktop computers cannot be carried around.
`Furthermore. only partial hardware is include and.
`therefore. still requires the user to provide the neces-
`sary video signal source such as an external antenna,
`or a video cassette recorder (VCFIJ input
`in order to
`function.
`
`SUMMARY OF THE lN\.lENT10N
`
`In a first aspect, the present invention provides an
`entertainment system which is fully integrated into a
`computer and supported by software running on the
`computer. The invention provides An entertainment sys-
`tem lntegrated into a portable conlputer. comprising: at
`least one of a television receiver and a radio receiver;
`and a built-in antenna mounted to said portable compu-
`ter for providing broadcast signals to one of said televi-
`sion receiver and said radio receiver.
`According to a preferred embodiment of the inven-
`tion. all hardware. including electronic circuits and other
`components. for the entertainment system is fully inte-
`grated in a notebook computer. More specifically. the
`invention integrates television electronics. AIWFM radio
`circuits. at GD—FlOM (compact disk-read only memory)
`drive. and a miniaturized 8-mm \l'CFl into a notebook
`computer. such as an IBM Thinirpacl 75:10 computer.
`The entertainment system takes advantage or the ultra-
`high resolution thin film transistor. liquid crystal display
`{TFTILCD} which is already part of modern notebook
`computers. Hence. the entertainment system can be
`integrated into the notebook computer at minimum cost.
`The entertainment system comprises oi a tele-vi~
`sion.
`radio.
`removable CD-RUM audio andfor video
`disc. and a removable B-mm VCFI. Software running on
`the notebook computer provides a graphical user inter-
`face wherein the user can use a key stroke. mouse. or
`track point to tune to dltterent channels and adjust the
`volume. brightness, and contrast using icons which
`mimic controls that might be found on a conventional
`television, radio. t.-‘CF! or GD-ROM drive. In adcfiticn. the
`software has the capability ct displaying the television
`image in a separate window on the display while simul-
`taneously displaying information on applications run-
`ning in other windows.

`DETAlLED DESCRIPTION OF A PREFERRED
`EMBODIMENT OF THE INVENTION
`
`Referring now to the drawings, and more particu-
`larly to Figure ‘i. there is shown a system block diagram
`of the entertainment system integrated into a notebook
`computer according to a preferred embodiment of the
`present invention. As shown in l-‘igure 1. the television
`receiver 1 and accompanying circuitry receive a pluraiity
`of broadcast television signals from either an external
`source connected to jack 3 or an antenna 5 to provide a
`television picture which can be displayed on an inset or
`a computer display 2.
`it is important that a built-in
`antenna be provided since. in order to be fully portable.
`a constant source of broadcast signals must be availa-
`ble, In the preferred embodiment of the invention. the
`display used is 3.12.1 inch color thin film transistorfliquld
`crystal display {TFT.-‘LCDJ. as used in the IBM Thinkpad
`notebook computer.
`An B—mm VCR 7 or a CD-ROM drive 8 provid e alter-
`nate sources for video signals. Each of the television
`
`receiver 1. the B-mm VCR 7. and the CD-ROM drive 5
`are connected to the display 2 via the system bus 9 of
`the notebook computer. The 8~mm VCR 7 may be built
`into the notebook computer but is typically added to it as
`a detachable module. as indicated by the dashed tines.
`The CD- ROM drive 8. which may also be built into the
`notebook computer but. again. is typically a detachable
`module.
`is capable of playing computer CD—HC}Ms.
`audio CDs as well as the newer MPEG video CDs.
`The antenna 5 is also connected to an AJWFM
`receiver 4. The audio output of the AMIFM receiver 4 as
`well as the audio output from television receiver ‘l. 8mm
`VCR 7, and CD-ROM drive 3 are supplied to audio cir-
`cuits 6 providing an output to a speaker 63 or. selec-
`tively. an earphone (not shown).
`The notebook computer includes a system proces-
`sor" 10. such as an Intel Pentium‘ or IBM PowerPC"
`microprocessor: The system processor is supported by
`read only memory (ROM) 11. which stores the basic
`inputroutput system {EH05}, and random access mem-
`ory {FlAM) 12. which stores portions of the operating
`system (08) and application programs. Also. the note
`book computer has a hard disk drive 14 having suifi~
`cient capacity to support multimedia programs run on
`the computer. The hard disk drive ‘l4 may be aug-
`mented by a second hard disk drive 15 in the term of a
`d etachable module, as indicated by the clashed lines. In
`addition. a floppy diskette drive 13. which may be built
`into the notebook computer but is typically provided as
`a detachable module. is provided to receive input from
`removable diskettes.
`Software. shown in the flow charts discussed
`
`below. running on the system processor 10 is used to
`control the display or a television picture in association
`with the computer operating system (08) software that
`enabies the computer to undertake other functions con-
`currently. The quality or the television picture. contrast.
`brightness. volume. and channel selection can be oper-
`ated by using a mouse (or track point in IBM Thinkpad
`notebook computer) or keyboard. Similarly. software is
`used to control the other muilimeclia functions. as will be
`described in more detail.
`Figure 2 is a pictorial diagram of a notebook oorn~
`puter 20 of the type which may incorporate the enter-
`tainment
`system aocording to the invention. The
`notebook computer has 3 TFT display 21 and a key-
`board 22. Dutwardly. the notebook computerloolss very
`much like any other notebook computer with the excep-
`tion ol the added telescoping antenna 23. which is con-
`veniently housed in an edge of the to|d—up Tl-‘F display
`21. it will be understood that other types oi extendable
`antenna. such as spring-loaded rabbit ears. may be
`used.
`In the preferred embodiment.
`the television
`receiver circuitry and the AMIFM radio circuitry 4 is
`positioned behind the Tl-‘I’ display 21.
`figures 3 and 4 show a view of the IBM Thinlqaad
`‘F508 computer with the keyboard 22 lifted to allow
`access to the removable modules. in Figure 3. a battery
`16. and a hard-disk drive 14 are shown with ailoppy dis-

`Katie drive 13 removed to make room lor either the arrm
`VCR T or the CD-ROM drive 8. in Figure -1». a configura-
`tion is shown where the floppy diskette drive 13 is
`swapped for the B-mm VCR T. and the removable hard
`disk drive 14 is swapped for the CU-FIOM drive 8. The
`removable hardware allows the entertainment system to
`be contained in one compact easy to carry chassis and
`provides the options for users to choose whether to use
`these the additional errtertainrnenttunclions or not. The
`removable 8-mm VCR ? and C[J—FtOIvI 8 can operate as
`entertainment functions which send video signats to tal-
`evision receiver 1 circuits for processing and displaying
`onto the TFULCD display 2 and audio signals to the
`audio circuit 6. or can iunction as storage devices via
`the Small Gonputer System lnterlace (SCSI) and sys-
`tem bus 9 to communicate with the notebook contou-
`ter's standard ports. such as the system microprocessor
`10. RAM 12, and serial and parallel ports {not shown}
`tor other computer tasks.
`The additional hardware of the notebook entertain-
`ment system does not substantially increase the power
`consumption for normal usage. This is because the
`TFTILCD display 2, which is used for both computing
`and entertainment. typically consumes the most power
`of any component (typical power consumption 5.65 watt
`in battery mode . 3,95 watt in AC adaptor mode}, The
`power to the unused part ot the system. whether used
`as a computer system or entertainment system. can be
`turned off it not in use to save power.
`The total weight 01 the electronic circuits ol the tele-
`vision receiver
`1.
`the AMIFM receiver 4. and the
`antenna 5, is estimated to be 8 ounces. Since audio cir-
`cuits and TFTi'LCD display controller circuits are
`already part of the notebook computer. the television
`receiver 1 and AMIFM receiver at radio may exploit
`these existing circuits and theretore add only minimum
`weight to the notebook computer.
`figure 5 shows a detailed block diagram of the tel-
`evislon receiver 1. shown in Figure 1. The television
`receiver 1 is comprises an RF (radio trequency) tuner
`30 which includes electronictuning circuits. videoiauclio
`IF [intermediate irequency) and detector circuit 32, and
`local processor 33 which performs signal conditioning
`and converts NTSC (National Television System Com-
`mittee) signals to digital FIGB {red—green-blue] signals.
`To receive broadcast television signals. the antenna 5
`picks up an incoming RF signal and the RF tuner SD
`tunes the VHFIUHF bands. The television receiver can
`be scanned electronically and continuously under the
`control of soltware until a detectable channel is cap-
`tured ‘oythe HF tuners 30 electronic tuning circuits. It is
`desirable to have the option of the lectronic %nr-Ling
`for television reception since the portable entertainment
`-system with the notebook computer may be used in a
`location of television channel selection unfamiliar to the
`user.
`
`The desired television channel may also be
`selected directly by using keyboard or mouse through
`the software. Once the incoming RF signal from the
`
`antenna 5 is converted to an lF signal, the lF signal out-
`put from the RF tuner 30 is fed to an IF amplifier 31 to
`be amplified. The amplified IF signal is then passed into
`the videofaudic IF and detector 32 which can be imple-
`mented by an integrated circuit such as the TA868-D
`from Toshiba or other ofi—the-shelf electronic compo-
`nents. The audio signal can he extracted by the
`videofauclio IF and detector 32 from the amplified lF sig-
`nal as an intarcarrier component at 4.5 MHz. while the
`desired output of the audio signal from the videofaudio
`IF and detector 32 is input to the audio circuits (figure
`1) for audio processing and output to the speaker 54.
`the video output signal from the videoiaudio IF and
`detector 32 is input to the local processor 33 to be fur-
`ther processed and converted to digital RGB signals.
`with 6-bits for each ot the RGB signals. The RG8 data
`is supplied to the TFTFLCD controller of the notebook
`computer display.
`External connectors for audio and video inputs are
`also available. For acrample. a video camera recorder
`may provide the video and audio signals to the enter-
`tainment system and use the TFTILCD display 2 for dis-
`playing its video picture. External video and audio
`inputs are connected to the videoraudio IF amplifier 31
`and the external video and audio signals are further
`processed in the same fashion as a broadcast television
`signal.
`the AIWFM radio
`Fteterring now to Figure 6,
`receiver circuit 41 shares the local processor 33. the
`local bus 34 and the antenna 5 with the teievision
`receiver I. The AMIFM radio receiver circuit 41 can be
`implemented with an integrated circuit in a single pack-
`age which is readily available as an oft-the-shetl item
`such as radio module TE!-‘l.5T57 from Phillips. The note-
`book computer entertainment system software and the
`local processor 33 help to provide the following addi-
`tional functions trom the AMIFM receiver circuit 41.
`which can be operated trcm rnouselkayboard 22 of the
`system. The functions include automatic electronic tun-
`ing, volume, scanning. preset and AWFM channel
`selections.
`.A difiiculty with embedding the combination of
`entertainment system and notebook computer into a
`single notebook computer chassis is the pachaging oi
`all the hardware oi the entertainment system with the
`hardware of the notebook computer clue to the con-
`straints ot space availability and light weight of the entire
`notebook computer system. A solution provided by the
`present invention is maximization oi the shared use of
`hardware arcl circuits: for example, referring back to
`Figure 1, the teievision receiver 1 and the NWFM radio
`4 share the same antenna 5 and audio circuits 5.
`Fteierrlng now to figure 7. in a similar manner, a
`single audio circuit 50 including an audio mixer 61.
`audio amplifier 62. earphone jack 64, and speaker 63 is
`shared by all the entertainment functions and system
`computer. The audio mixer 61 selects an audio input
`lrom either the TV audio 65. the AM.-‘FM radio audio 66.
`the Bmrrl VCRIGD-ROM audio 6?. or the computer

`
`audio sa. The output of the audio mixer 61 is input to the
`earphone jack B4 and to the power amplifier 52 for
`amplification to the speaker 63 to provide sound for the
`entertainment system.
`As mentioned above. software running on the
`microprocessor is used to control the entertainment
`functions. Figures 3 to 15 show the software flow dia-
`grams as well as illustrate the various user controls for
`selecting between and controlling the individual enter-
`tainment components. Starting at block 100 at Figure 8.
`and proceeding immediately to block 102, the user is
`requested to input a selection for the type of entertain-
`ment that is desired. That is. television. AMIFM radio.
`CD-ROM. or VCR.
`Figure 9 shows an example of a graphical selection
`screen that may be displayed for the user to pick from.
`In this example. the television has been selected by
`marking the box 104 acliacent to the television selection.
`It at this point if it is desired to exit the entertainment
`system, the down arrow 105 may be selected. Selec-
`tions may be made by the user by, for example. key-
`stroke. mouse. trackball, or (or track point in IBM Think-
`pad notebook computer). touch screen, or any other
`input means.
