Embodiment
Fig. 1 illustrates consumer's digital audio video system of simplification.The signal source of packing, the audio frequency and video of compression is shown as with decoder with control data and is connected with display.Receiver IRD100 specially is connected with reception antenna 50, and the signal of modulation also can be provided from the cable distribution network (not shown).The packetized signals of this modulation is by tuning, demodulation, and also the program that the user determines is separated in the piece that is designated as bag source 109.The output in bag source 109 comprises by the transmission package of the audio frequency and video of mpeg decode and control data stream, to produce the Voice ﹠ Video signal by decoder 117.The output of decoder 117 is connected to the display 300 that is used to monitor.Other packetized signals source with dashed lines is shown as the alternative data flow of being carried out mpeg decode by decoder 117.Therefore decoder 117 can be used to therefore reduce the cost in other source to decoding from the transport stream in external packets source.For example, the computer of packing output signal can be represented to form in bag source 75.Sort signal can be to extract from computer storage or produce such as computer network from external source.This computer sources can be from the audio frequency and video and the control data of magnetic disc store regeneration compression.In addition, digital video display can be represented in bag source 75, such as the DVD checker-work.Can provide another transmission package source by the magnetic tape reproducing register, bag source 200, it can have such as with D-VHS or the corresponding form of DVC standard.
Consumer's digital video receiver of simplifying, register and display system are illustrated in the example block diagram of Fig. 2.This system adopts digital video signal source, for example integrated receiver decoder or IRD100, and audio frequency and video monitor display device 300 and digital video tape recorder 200, this digital video tape recorder 200 for example adopts D-VHS or DVC form.In illustrated system, the digital video representation signal is modulated on the RF carrier wave and by antenna 50 and receives.Antenna 50 is connected with integrated receiver decoder IRD100., the carrier wave of modulation can be provided to receiver 100 by the cable distribution system (not shown).This integrated receiver decoder 100 is tuned to RF carrier frequency and the decoding and the transmitting data stream of mpeg compatible thus.
This transmitting data stream can be decoded, to produce analogue audio frequency and vision signal, to be monitored by audio frequency and video display 300 immediately.The output signal of this decoding is by being connected receiver, signal 101 between IRD100 and the display 300 and 104 expressions.Consideration designation number register 200 to cost does not comprise mpeg encoded and decoding.Therefore digital recorder 200 plays the function of bit stream register/reproducer, postpones ability so that time migration or program to be provided.The omission that MPEG handles and make and can not come and go for simplifying required complexity of non-standard rate play capability and degree, the image in slow motion or the track manner of playback is reset.Therefore, generally speaking, receiver 100 will be connected to digital A/V bus 112 with the bag stream of mpeg compatible, with by register 200 records.Similarly, come the playback bag stream of self-recorder 200 to send back to receiver, so that mpeg decode produces audio frequency and video.The status message that omits additional consequence that MPEG handles and be display message on the screen or OSD form in register can not make up or be added in the pack bitstream of playback.Therefore, the operating state of register can not offer the user significantly.
In addition, because just at record, resetting and stopping mode obtaining the register pictorial data, then the user does not know what the response of the control command below the register is.For example change to the rewinding meeting and cause that the image of resetting is such as switching to incoming bit stream from playback, this is known electronics to electronics or E to the E state, perhaps, the image of for example resetting can disappear and be replaced by the freeze frame that IRD produces, and perhaps motion video is mixed captions by color field.Therefore, as the sign of recording mode response, the user can not determine and knows these visual display effects.
System shown in Figure 2 has shown first creative jockey, and wherein Xie Ma transmission bit stream is connected to register 200 from receiver IRD100 by BDB Bi-directional Data Bus 112.This transmission package stream is connected to data/address bus by interface 110 and receives at register 200 places by means of receiving 210.This interface is by control data stream and Be Controlled, and this data flow is to carry on the separated wires in data/address bus 112.Control signal can be extracted by start-up control switch (not shown) from user input, or the IR remote control command that is produced by the user produces.For example, the user can select to monitor the digital audio vision signal that is received by antenna 50.Can select this receiver by touch or remote control.The selection of receiver can cause monitoring automatically this demonstration selection, i.e. this demonstration is automatically switched to the audio frequency and video output that monitors mpeg decode.This user can select digital recording mode, and it can make by bus 112 and be coupled to register and opening entry from the transport stream that IRD receives.Similarly, select the manner of playback of digital recorder can make the data flow of playback be coupled to the decoder 117 of receiver 100, so that decode by bus 112.
Be coupled to register 200 and processed with the packetized signals of mpeg compatible, so that by piece D.REC210 record.A buffer memory is included among the piece D.REC210, and data are flow to row buffering, to set up the signal than the more suitable record of packetized signals that comprises the data pulse with variable interval.Buffered data streams is read from buffer, to form record format synchronization blocks, its available error-detecting correction data word code.The formative data flow of this synchronization blocks can be modulated so that be recorded like that as mentioned above, and from record block D.REC210 by selector switch A4 coupling.Control selector switch A4 and A5 according to the D-VCR working method of selecting.For example, shown that in Fig. 2 switch A4 and A5 have digital record contact DR and digital replaying contact DP, be used for data flow is coupled to rotary head device 250 or output stream therefrom.For analog operation, switch A4 and A5 adopt another position, AP, analog record and AP emulated for playback.Be coupled to from the formative data flow of the synchronization blocks of D.REC210 and place magnetic head assembly 250, so as on tape record.
In manner of playback, the formative data flow of the synchronization blocks of record is reproduced from tape by the transducing head 251 that is positioned on the device 250.The signal that is recovered is by digital replaying piece D.REP220 demodulation, to remove any record channel modulation.By means of the data word of inserting before the record signal of resetting is carried out error-detecting and correction then.After error correction, the synchronization blocks format is removed, and the bit stream that is recovered has identical with the packet format that is coupled to register basically packet format.Bag stream from piece D.REP220 is coupled to interface 210, and it should wrap stream in response to the manner of playback of register and be coupled to BDB Bi-directional Data Bus 112, so that by decoder 117 decodings.
100 pairs of bag streams with mpeg compatible of integrated receiver decoder are decoded and are produced the video/audio output signal.For example, Fig. 2 illustrates video and audio output signal 101 and 102 and component video signal 104, for example S-Video., the vision signal of this digital replaying does not have usually by shielding the recording status information that upward demonstration or OSD device provide.
The receiver IRD100 that shows in simplified form in Fig. 2 comprises controller CTRL115, and it provides the The whole control of receiver, and is for example tuning, unwraps head control along separate routes, and bus interface is controlled and is coupled to the bag stream of mpeg decoder 117 and selects.In addition, can indicate the state or the working method of receiver by means of display message on the screen on the vision signal that is added to decoding.Controller 115 can be constructed display message on the screen or be read the message of predetermined storage from memory block MEM510.This screen is gone up display message or OSD is coupled to OSD inserter or adder, piece 520, wherein, the formatted so that analog video of this message shows, and be added to or with the vision signal combination of mpeg decode.This video with osd signal is by output amplifier 118 outputs, so that shown by monitor display 300.
The selector switch A3 of SEL280 can provide primely and be coupled to the signal selection that screen is gone up demonstration adder 275.Provide creationary connection at the switch A3 shown in Fig. 2, the video composition of output signal output 102 is coupled to the input of the last demonstration of screen adder 275.The status message of the register reproducer 200 that therefore, for example produces in playback can be added to from the vision signal composition 102 of output transmission package stream decoding.Therefore, can see the replay signal that is added with the mpeg decode that shields the digital form generation of going up message, signal 103 by display 300.
During the analog operation of register reproducer, switch A3 goes up emulated for playback signal VHS and shows adder 275. therefore to screen, and during analog operation, OSD message is added in the emulated for playback vision signal.When selecting digital record, OSD message can advantageously be added to from the analog video signal 102 of the bit stream decoding reset.Therefore, connect by favourable feedback, recorder status message and video composition make up and export as analog signal 103.
The switch A2 of selector SEL.280 advantageously provides the bypass screen and goes up the connection that shows adder 275, and allows output signal 102 to be directly coupled to monitor display 300.Therefore the bypass of switch A2 action allows to watch the output signal of decoding and gets rid of because the possibility that 275 pairs of signals of adder reduce.When the standby mode register is closed, maybe when watching non-record " in real time " bit stream of decoding, can automatically select bypass path A2.In order during analog record, to allow to watch the non-tracer signal of decoding, can manually operate this by-pass switch.For example by E/E register passage, this favourable bypass connects has got rid of unnecessary analog recorder signal processing, and itself can damage the signal 102 that digitlization produces.In addition, this favourable bypass functionality can for example be simplified by Mechanical Contact, allows receiver IRD100 to be connected to monitor display 300 such as switch A2, and no matter the operating state of register 200.
On-screen display generator 270 produces with specified levels and vertical synchronization formatted message regularly, makes that it was displayed on the precalculated position of display screen when this message was inserted into vision signal., when working in the digital replaying mode and adopt this above-mentioned favourable feedback to connect, can utilize the vertical synchronization different regularly advantageously to produce OSD message with the analog recorder duration of work.Level that these are different and vertical synchronization have regularly advantageously compensated inhibit signal diffusion and the mpeg decode delay issue of running in receiver 100.Therefore use different OSD synchronization timings advantageously in the work of analog or digital register, to obtain identical predetermined message position basically.
The time delay of processing and mpeg decode can be accumulated as the period of multiframe.Multiframe postpones or the time migration meeting causes OSD message prior to the visible phenomenon of the playback of reality.The time migration meeting such prior to replay event of register OSD message is rendered as the result of user's control command and the delay of corresponding playback image effect occurs.When displayed record time code signal or register tape timer, this time migration meeting causes bigger problem.For example, during magnetic tape reproducing, from the screen of register tape timer show or writing time coded signal OSD can see special event.The time of being seen allows the position successively of selected incident., if the time of being seen is used for the in-edit of the electronic editing that carries out between register, the scene of edited result will be located between preview period before the selected scene.By delay, message produces, message communicating, and tape timer time yardage or counter are revised in presenting or passing through of OSD, and the time migration effect between this message and playback image can advantageously be suppressed.In register 200, can be the delay of DLY.207 by switch A7 or A8 selected marker.For example, when the vision signal 102 of decoding is fed the register OSD message of inserting at piece 275 places,, can produce the instruction of OSD message in response to controller 205.Come the message command signal CMD of self-controller 205 to be illustrated as and be coupled to switch A7 and delay line DLY207.In response to being register 200 selected modes, promptly analog or digital comes control switch A7.Switch A7 is displayed on digital form, and selects the delay version from the signal CMD of delay line 207.This delay instruction signal can cause the generation and the insertion of OSD message, and it overlaps with the vision signal of decoding basically.The device of a replacement has adopted switch A8, and it can be inserted into delay line 207 in the output of osd generator 270.In this device, switch A7 is connected to the output of controller 205.Switch A8 also can be used for signal CMD is postponed to be coupled to bus 112 and IRD100.In the access signal by retardation ratio such as DLY.116 being incorporated into memory or the output signal of memory, the also time migration between the delay image of recoverable OSD message and decoding in receiver 100.Utilize the whole bag of tricks, for example by means of the delay of using clock data to latch, shift register, one-shot multivibrator or the like can obtain the synchronous of image and OSD of resetting.For example during carrying out the edit mode of preview by the algorithm process that shows number, tape timer or timing code OSD can be synchronous with the image of decoding.Therefore can import the image of selection and identical demonstration number, so that finish electronic editing.During the analog operation of register 200, come the command signal CMD of self-controller 205 not postpone, and switch A7 is directly coupled to generator 270.
In another creative embodiment, display message can advantageously utilize display capabilities on the screen of receiver 100 on the screen that is produced by register 200.The message that register provides can be coupled to receiver 100 by the pilot of data/address bus 112, inserts so that shield demonstration at the piece OSD520 place of Fig. 2.This register message data can be formatted as word message by generator 270, and attaching thereon has a mark or label.The word message of mark that is shown as signal 271 is coupled to the controller 115 of IRD100, to separate from other control bus data.The word message that separates later is coupled, so that carry out display formatization and video insertion by OSD520.Produce word message in response to the OSD command signal CMD that comes self-controller 205.As mentioned above, at piece 207 places, signal CMD can be postponed., the word message from piece 270 can be postponed in the delay 207 of another point owing to switch A7 insertion.
In another creative embodiment, receiver 100 comprises memory 510, and it comprises receiver screen and goes up the specific OSD message of display message and register 200.Go up the special message that idsplay order signal CMD can the access record device in response to register screen, the last idsplay order signal of this screen can be coupled to controller 115 by control bus.In register 200, produce screen by controller 205 and go up idsplay order signal CMD, the also definite in addition message that will produce of controller.Therefore, command signal CMD can advantageously be coupled to 100 pairs of receivers and be stored in the format that the special graphical messages of register in the memory 510 is carried out access and demonstration.
In the receiver 100 of another creative structure, between register word message or receiver graphical messages, select in response to register instruction adaptability ground.Selection between register literal or IRD graphical messages show allows to have the interconnection of different qualities and the register of setting and various years and receiver.For example, an old receiver can be connected to the register of making recently, and therefore, this receiver memory does not comprise the graphical messages of pre-programmed, comes record support device screen to go up presenting of display message.Therefore this receiver can show the simple text message that is produced by register.On the contrary, the graphical messages of the various products that more modern receiver can be by selecting the various manufacturing age be carried out pre-programmed, and these various graphical messages can replace the register word message and are shown.By appending to sign or the label in the word message, can be reduced at the selection between simple text or the graphical messages.For example, this sign or label can comprise command signal CMD, and it selects and start the special message of needed register.In addition, this label can provide enough capacity, with the characteristic information of announcement recordings device, and the producer of those and register for example, model, version or version height and the relevant information of sequence number.When controller 115 received this literal message with sign or label, this sign or label were translated, and caused selecting from IRD memory 510 a register special pattern message., if receiver memory special register message of no use or carry out pre-programmed for the specific message of register characteristic then should start format and show additional simple text message by sign.As mentioned above, can insert a delay cell and compensate OSD message, the decoding of literal or figure and playback is the displacement in the time between the decoded picture and space.
Fig. 2 illustrates a monitor display, and it has three input end of analog signal: AV signal 101 and 103, audio frequency and component audio signal 104 (for example S-video), or brightness and chrominance component Y, Pr, Pb.In addition, by radio frequency (RF) signal RF IN, display 300 can receive the Voice ﹠ Video signal.A known signal selector 310 is coupled to video and synchronous processing circuit (not shown), and it produces image and shows in combination.Start switch on the display 300 by the user, perhaps start remote control command, with regard to may command signal selector 310 by the emission of modulation IR control flows by the user.By the automatic control of selector switch 310, can advantageously select illustrated these three base-band input signals.For example, just can automatically select to comprise the input signal of register OSD state display message to the selection of digital record or manner of playback.This recorder status OSD can be produced as described above.In addition, the permission of many baseband signal inputs can allow the interconnection of the special device of function.For example, by using such as output signal 101, or component video signal 103,, just the signal of non-record can be decoded from IRD100 direct viewing easily to form A/V signal 103 with being used for the output signal 102 that register OSD inserts.
Fig. 3 illustrates for example operating position of display 301 of display that cost reduced.In order to reduce cost, the quantity of signal input part can be restricted to for example RF input, one-component video or S-video inputs and an AV signal input.This outstanding selection of the selector 280 of Fig. 2 and bypass capability allow display 301 to bring in monitor log and material non-record by single A/V input., this demonstration can advantageously utilize component video signal to connect, and outside connecting at signal, definite and control demonstration input is selected.For example, owing to can suppose that component video signal or S-VIDEO signal provide than the better displayed image quality of NTSC code signal, this component signal that is coupled to the component signal input can automatically cause the selection in component signal source.Therefore, when component and component signal were coupled to display 301 inputs 1 and 2 respectively, input controller had such logic, and its is predetermined selects component signal as with reference to input., this is imported selection automatically and can stop and monitor the signal comprise the special information displayed on screen of register that comes from register 200 couplings of Fig. 2., this is selected to be advantageously used in the remote control that starts AV signal with reference to input automatically and selects, for example the signal 103 on the input 2.By allowing or interrupt output coupled signal 104, and component signal 104 is carried out creative control, can on display 301, watch the signal that comprises information displayed on screen by register 200 couplings from IRD100.For example, the signal that the user selects non-record bit stream promptly to receive will cause the controller 115 of receiver 100 to begin to produce or export to have for example component signal 104 of S-VIDEO form.Selection to the recording picture signal that is used to show will cause controller 115 to interrupt producing or output component signals 104.Therefore, the controller 312 of monitor 301 is connected to the component signal input, to come the disappearance of detection signal 104 by signal 309, and making input selector 311 switch to AV signal 103 on the input 2 for example from the component input signal 104 on the input 1, input 2 is connected to the selector 280 of the register 200 among Fig. 2.
