Other purpose, characteristics and the effect thereof of present invention will be described in detail with reference to the accompanying example will have further clear and definite understanding to the present invention.
Describing the digital satellite broadcast receiver reservation of developing according to the present invention in detail with reference to accompanying drawing watches with the correct example of method for recording as follows: (annotate: the structure and the effect that illustrate and illustrated in this specification, at least be an example of the present invention explanation, but technological thought of the present invention and core texture thereof and effect are not limited to following several particular instance.) promptly,
Fig. 1 is the conceptual module figure that above-mentioned " No. 38808 " digital satellite is play receiver, and it comprises: the antenna 101 that can receive high frequency band value digital satellite play signal; The high frequency band value satellite-signal that receives by above-mentioned antenna 101 is carried out low noise amplifier (the Low Noise Block that low noise amplification is handled; LNB) 102; The satellite-signal that to export from LNB102 is divided into a plurality of signals, and a plurality of transducers 103 of outwards exporting; A plurality of satellite-signals that reception is exported from a plurality of transducers 103 are adjusted into the channel of each servo request by a plurality of tuners, and after converting the form of transport stream (TP) to, to the main frame 110 of each servo output; Be located at each respectively independently in the space, and in the channel that main frame 110 is adjusted, receive it by main frame 110 and send the channel code stream of request, carry out a plurality of servies 120 that shown after descrambling and the encoding process.
Fig. 2 is the detailed block diagram about above-mentioned main frame 110, wherein is not provided with display unit (for example, TV).Main frame among Fig. 2 is by a plurality of tuners and demodulator (111a～111d) form, it also is made up of following several structures: promptly, the satellite RF signal that reception is exported from a plurality of transducers 103, and be adjusted into the channel of the request of sending in each servo simultaneously, carry out demodulation process then, and with a plurality of tuners 111 of TP form output; For the TP signal that will export sends each servo to, those signals are carried out a plurality of channel TP distributors 112 of allocation process from each tuner in a plurality of tuners 111 and demodulator; Main control system motion comprehensively, and the CPU (CPU) 113 of the data communication between main control system and each servo; Be received in the main frame TP signal that is distributed in the distributor 112 by CPU113, and export or receive from the signal of each servo output to each servo, the main signal that sends CPU113 then to sends or receiver 116; The request of sending according to each servo is with the modulator-demodulator 114 of satellite play signal transmission place carrying out two-way communication.
At this, each tuner and demodulator in above-mentioned a plurality of tuner 111, with QPSK (Quadrature Phase Shift Keying: the mode quadrature phase change over switch), the satellite-signal of adjusting channel is carried out demodulation process, and these conversion of signals is become the TP form.
Each servo is to receive the TP signal that is transmitted by main frame 110, and they are reverted to servomechanism installation IRD (the Integrated Receiver ﹠amp of original digital picture and audio signal; Decoder: Ji Chengjieshouqi ﹠amp; Decoder).They link to each other with showing the display unit (for example, TV) that has been encoded as vision signal, and its inside is not provided with satellite receiver turning.
Above-mentioned modulator-demodulator 114 is not located in each servo, and only is located on the main frame 110.Each servo all by the modulator-demodulator 114 of main frame, carries out signal with satellite play service provider and receives or transmit.That is, main frame 110 sends the purchase information of each servo to satellite play service provider separately, and its result is resend to corresponding servo.Therefore, need not modulator-demodulator to each servo to be installed all, this has significantly reduced user's expense expenditure.
If append the module that installation can be carried out the inverse multiplexing processing for above-mentioned main frame 110, main frame 110 will be by the inverse multiplexing processing, analyze additional data information such as performance guide information, and these information are kept in the memory 115 in the main frame 110 with the form of database (DB).At this moment, each servo need not to preserve additional data information separately with the form of database (DB).That is, after specific servo request provided additional data information, main frame only in the additional data information memory 115 in, read the information of necessity, and sends it to corresponding servo.For convenience of description, the form with database (DB) is kept at performance guide information in the memory 115, is designated hereinafter simply as EPG DB.Because each servo need not to preserve additional data information separately with the form of database (DB), therefore can increase substantially the service efficiency of memory, and the memory span that can dwindle each servo, and effectively reduce user's cost.
At this, can utilize wired connection between above-mentioned main frame 110 and each servo 120, also can utilize wireless linking to each other.If utilize wireless connections main frame and each servo, just there is no need to prepare the wiring between main frame and each servo, so to the installation of each servo or move all very convenient.What relate among the present invention is the example of radio communication between main frame and each servo.
In addition, be equipped with CAS on each servo, they carry out user's registration and authentication by being inserted in the smart card among the CAS, and the relevant information of chargeing is carried out maintenance and management, also scrambled data are carried out scramble process simultaneously.At this, the smart card that is inserted among the CAS is applicable to the unified smart card on all servies (family smart card), and the retrievable unified smart card quantity of user equals to be registered to the servo quantity of satellite play service provider.That is, an ID and password can only be registered in the above-mentioned smart card, also each ID of servo registration and password can be given respectively.
If a smart card has only been registered an ID and password, so any servo all can authenticate this user ID and password.
If in a smart card, give each ID of servo registration and password respectively, so corresponding servo only can authenticate one's own user ID and password.At this moment, the security measures of each servo are very perfect.
In this external smart card, when giving each ID of servo registration and password respectively, all registrable in any one servo have authentification of user required main ID and a password.For example above-mentioned main ID and password are meant, only supply the user ID and the password of guardian's (for convenience of description, hereinafter to be referred as main user) uses such as father and mother, can be main ID and password with the ID and the password setting of main frame at this.Promptly, servo ID and password can only obtain authentification of user in corresponding servo, but main ID and password can obtain authentification of user in all servies, if in a servo, utilize main ID and password to obtain authentification of user, can in this servo, set the reservation of other servo that comprises it and watch or reserved recording task so.
The user can set the reservation of specific channel and watch the time in advance at least more than one servo in a plurality of servies, and at this when time is up, by the broadcasting channel programme information of servo automatic reception main frame, and it is presented on the display unit.
In addition, the user also can set the pre-recording time of specific channel in advance at least more than one servo in a plurality of servies, and when this time arrives, by servo by main frame, the programme information of automatic reception broadcasting channel, and it is saved in save set is presented on the display unit.
As mentioned above, reservation is watched or the pre-recording assignment procedure closely similar.Difference between them is that at setting-up time then, the assignment procedure that reservation is watched is presented at channel program on the display unit, and the assignment procedure of pre-recording then is saved in information in the save set.For convenience of description, below reservation is watched or pre-recording is referred to as reservation and watches and record.
If the user in a servo, sets reservation to other servo and watches or the pre-recording time, this servo will be watched or the pre-recording set point to the reservation that main frame transmits servo so.In addition, main frame retransfers this set point to corresponding servo, so that corresponding servo is grasped the reservation of oneself is watched or the pre-recording set point.
At this moment, can watch and the pre-recording set point according to the reservation of each servo by above-mentioned main frame, corresponding servo preengage accordingly watch or pre-recording control, also can be by each servo according to watching and the recording setting value to the reservation of oneself, the reservation of oneself is watched and recorded and control.
To watch and the pre-recording set point according to the reservation of each servo by main frame, corresponding servo preengage watch when controlling with pre-recording, if watching with recording time, the reservation that each servo is set arrives, main frame will be adjusted the channel of preengaging when watching with recording setting automatically, and it is carried out demodulation, then it is sent to corresponding servo.When the time is watched in the setting reservation, corresponding servo will carry out encoding process to the channel program that main frame transmits, and it is presented on the display unit so; And setting pre-recording during the time, corresponding servo then is saved in it in save set.At this moment, if the power supply of servo is in closed condition, main frame can be opened the power supply of this servo, can also open the power supply of oneself in corresponding servo.
By each servo basis the reservation of oneself is watched and the recording setting value, watch and record when control to oneself preengaging, main frame sends current time information to each servo, each servo is then watched with the recording setting value the reservation of current time and oneself and is compared, and watch in the reservation of oneself and to send the request that corresponding channel is provided to main frame when reaching with the recording setting time.
Main frame can be adjusted the channel of the request of being sent by each servo, and it is carried out demodulation process, then it is sent to corresponding servo.When the time was watched in the setting reservation, servo carried out encoding process to the channel program that main frame transmits, and it is presented on the display unit, and is setting pre-recording during the time, then in the save set with its preservation.At this moment, if the power supply of servo is in closed condition, main frame can be opened the power supply of this servo, can also open the power supply of oneself in corresponding servo.
Fig. 3 is that the menu screen exemplary plot required with recording time watched in the reservation of setting in a servo of developing according to the present invention.That is, in a plurality of servies, the user can utilize input units such as remote controller, shows the menu screen as Fig. 3 a in any one servo.If the user in the menu item of menu screen, has selected reservation to watch and the recording setting project, on display unit, the reservation of displayed map 3b is watched and the recording setting picture so.
At this, the user can watch the reservation of menu screen with the pre-recording menu item and weave into one group, shown in Fig. 3 a, watches and the setting item of pre-recording to select reservation simultaneously, also can show and select reservation to watch and the pre-recording menu item respectively.
Fig. 3 b is after the user selects the reservation of Fig. 3 a to watch and records menu, reservation watch with the recording setting picture on set reservation and watch that the reservation of desirable value is watched and set the picture exemplary plot.
That is to say, the reservation of Fig. 3 b watch with the recording setting picture on the servo options, be for setting that reservation is watched or the pre-recording time is selected the project of servo, will showing the servo identifier that can distinguish each servo on this picture.At this, each servo identifier can be set by the user, also can be by system's automatic setting.For example, the user can be set at the title in children or bedroom with being located at servo in the children bedroom.
In addition, the Type project among the present invention is for selecting reservation to watch the project that (Timer) or pre-recording (record) are set.Shown in Fig. 3 b, Type is set at that reservation is watched, channel setting is 201 channels, day settings are June 12, time set be afternoons 5 point, watch that time set is that 10 minutes, number of repetition are set at once.
The user can set mutually different reservation to each servo and watch and recording time, and can set reservation to any one servo in a plurality of servies and watch and recording time, also can watch and recording time setting reservation with all servies of host machine wired or wireless connections.
In addition, the user can watch that setting reservation with the servo of recording setting watches and recording time to carrying out current reservation, also can be to being not that a plurality of servies of all servies are set identical reservation and watched and recording time.
If set mutually different reservation will for each servo watches and recording time, need just should select setting to preengage the servo of watching with recording time, and set reservation for selected servo and watch and recording time, and this process is carried out on each servo successively, selects then " affirmation ".Do not watch and recording time if do not want to set reservation, select " cancellation " to get final product so.
If want to watch and recording time to the identical reservation of all servies settings that is connected on the main frame, can be set according to said process, also the menu item that shows " all servies " can be added in the servo option among Fig. 3 b, and set simultaneously.That is, in the servo option, select by " all servies ", set the value of type (Type), channel (Channel), date (Date), time (Time), time limit (Duration), repetition (Repeat) etc. then.
If watch that to carrying out current reservation setting reservation with the servo of recording setting watches and recording time, also can be such to said process, select current servo, and set reservation and watch and record desirable value, also the menu item that shows " current servo " can be added in the servo option among Fig. 3 b, select then by " current servo ", and desirable value is watched and is recorded in the reservation of setting current servo, just can only current servo setting reservation be watched and record, this mode can make the user more easily set the time that reservation is watched and recorded.
If set identical reservation to a plurality of servies that are not all servies watches and recording time, can set the reservation of each servo in a manner described successively watches and recording time, also can be presented on the picture among Fig. 3 b being connected all servo identifiers on the main frame, and utilize remote controller, select a plurality of servies simultaneously, set the desirable value that reservation is watched and recorded then, and select " affirmation ", just can set the restriction of a plurality of servies simultaneously and watch grade.At this, required a plurality of files select process identical entirely during duplicating or deleting in the process of selecting a plurality of servies and the computer, and the personnel that are engaged in of the sector know this principle already, so will not describe in detail in the present invention.
On the menu screen in Fig. 3 a, the user desires to open restriction when watching menu item, must the correct password of input.Therefore, only when the user imports proper password, just understand the menu screen among the displayed map 3b.Its purpose is, prevents main user (father and mother) people (children) in addition by appointment mode, watches or preserve the broadcast program that father and mother abstain from.Suppose in the smart card that registration has main ID and password, have only the user of main ID of correct input and password just can open restriction so and watch menu item.In addition, above-mentioned main ID and password can also be the ID and the passwords of main frame.
At this, only illustrated by the input password to enter the example that menu item was watched and recorded in reservation.But mode that in addition can be by input ID and password or the mode of only importing ID enter reservation and watch and record menu item, and this depends on designer's hobby.
Fig. 3 a and Fig. 3 b are that the reservation of developing according to the present invention is watched and recording setting menu screen exemplary plot.So long as person skilled all can be carried out various deformation and change to it.Therefore, technical scope of the present invention is not limited to above-mentioned several particular instance.

Fig. 4 watches in the process with recording time the communication instance institute diagrammatic sketch between each servo servo B being set reservation by servo A.
That is to say, if main user inserts smart card in servo A, and input ID and password, through after the user authentication process, pass through the process among Fig. 3 again, servo B is set reservation watch and recording time that servo A watches the reservation of servo B with recording time information and sends main frame to so.Main frame watches the reservation of servo B with recording time information and preserved, and sends this temporal information to servo B, so that servo B grasps the reservation of oneself watched and recording time information.At this moment, the reservation of each servo is watched with recording time information and all can be saved in the smart card.For example, ID, password, temporal information and the reservation of each servo watched with recording setting information carry out the interface processing, and be saved in the smart card, after the user obtained authentication by smart card, specific servo will be grasped automatically to the reservation of oneself setting and watch and recording time information so.
Fig. 5 be control of the present invention reservation watch with method for recording in, main frame, servo B and and the user between the communication instance flow chart.
That is to say, periodically transmit current time information to each servo by main frame, each servo then to current time and the reservation of oneself watch with the recording setting value in temporal information compare.If the subscription time of setting is consistent with the current time, servo (for example, servo B) will send the request that subscription channel is provided to main frame so, and main frame is then adjusted the channel that servo B sends request, and after it is carried out demodulation process, send servo B to.When the time is watched in the setting reservation, servo B will carry out descrambling and encoding process to the channel program that main frame transmits, and according to subscription time, it is presented on the display unit, and setting pre-recording during the time, servo B will be recorded to it in save set according to subscription time.That is, setting pre-recording during the time, servo B will be to save set input beginning record command, channel program with reservation is saved in the save set simultaneously, and after subscription time finishes, give the record command of above-mentioned save set end of input again, to finish recording to broadcast program.At this, save set is meant the save set that is located on each servo, and it can be external memory storage or save sets such as VCR, DVD, HDD such as random asccess memory
Suppose in servo B, to have set and watch the time as the reservation among Fig. 3 b, servo B will receive 5 temporal informations in afternoon June 12 from main frame so, if current channel displayed is not 201 channels, servo B will send the request that 201 channels are provided to main frame, main frame then carries out modulation and demodulation to 201 channels to be handled, then it is sent to servo B, servo B will show the program of 10 minutes 201 channels of duration on display unit so.At this moment, if the user does not have within a certain period of time to servo B input function key, the power supply of servo B will be in closed condition so.
Fig. 6 further specifies above-mentioned control reservation to watch and the method for recording flow chart that it is that the diagrammatic sketch with recording setting control procedure institute is watched in the reservation of servo B.
That is to say that servo B receives (the 601st stage) behind the current time information from main frame, compare with recording starting time (the 602nd stage) watched in current time and the reservation set.By the comparison in the 602nd stage, if the current time preengage just watch and recording starting time that the power supply of servo B will be in closed condition so, promptly be in and prepare special topic (the 603rd stage).
If the power supply of servo B is in closed condition, so at first open its power supply (the 606th stage), if the power supply of servo B is in opening, check so whether the shown channel of display unit that is connected on the servo B is subscription channel (the 604th stage).
If judge in the 604th stage channel displayed it is not subscription channel, servo B will send the request (the 605th stage) that is converted to subscription channel to main frame, main frame is then adjusted and demodulation process the channel that servo B sends request, then it is sent to servo B.Servo B receives the channel program signal of the request of oneself sending from main frame so, and it is carried out descrambling and encoding process (stage 607), set then and preengage when watching the time, the image and the speech data that will carry out encoding process are input in the display unit, and setting pre-recording during the time, then these data are sent to (stage 608) in the save set.At this moment, if the reservation of servo B watch with the recording setting value in be provided with time restriction, servo B only fulfils in this time and shows or recording function so.If the user is input function key not within a certain period of time, the power supply of servo B will be in closed condition so.
Though only servo B is illustrated in Fig. 6, the present invention is applicable in all servies.
By above-mentioned description, so long as those skilled in the art all can carry out various deformation and change in not breaking away from technological thought scope of the present invention.
Therefore, technical scope of the present invention is not limited to above-mentioned several particular instance, but depends on patent claim of the present invention.
