And smart card can only be registered an identifier (ID) and password, also can be according to classification, login ID and the password of master unit and each sub-cell.
Such as, can only register at smart card under the situation of an ID and password, can only in master unit, import ID and the password of registering in the smart card, can obtain authentification of user, if the acquisition authentification of user, all sub-cell that just can normally enter master unit and be connected with master unit.Again for instance, no matter be at master unit or in any sub-cell, ID and the password registered in the input smart card can obtain authentification of user, if obtain authentification of user, all sub-cells that just can normally enter master unit and be connected with master unit.
If the home intelligent card behind the ID and password of input oneself, by master unit, can obtain authentification of user according to master unit and each sub-cell classification registration ID and password in relevant sub-cell.In this case, the safety of each sub-cell can be protected.
Such as, if the supposition smart card is according to the Category Accreditations ID and the password of master unit and sub-cell, the user transmits ID and the password of inputing among the sub-cell B to master unit, master unit reads ID and the password of sub-cell B from the smart card of CAS portion, the ID and the password that transmit with sub-cell B compare, if consistent, transmit the announcement information that obtains authentification of user to sub-cell B.So, sub-cell B just can enter normal use.
At this moment, the ID of master unit and password in any one sub-cell, can both obtain authentification of user not only at master unit.This is the operable examples of father and mother.That is, the ID of sub-cell and password only in relevant sub-cell, can obtain authentification of user, and the ID of master unit and password can both obtain authentification of user not only at master unit in all sub-cells.
And smart card also can be according to actual user's difference storage ID and password.In this case, the user imports user ID and the password of oneself in certain unit, if obtain authentification of user, can receive the suitable program of oneself watching.
At this moment, HDD 290 is installed in master unit, master unit and the shared HDD290 of each sub-cell can carry out pre-ordering or video recording in real time.
Here, the user can be provided with pre-ordering and video recording in real time in master unit or sub-cell, the video information that is provided with in each sub-cell is sent to master unit.And the authentification of user of master unit or each sub-cell can use the ID and the password of master unit or sub-cell, also can use user ID and password according to actual user's Category Accreditations.
An embodiment is provided with pre-ordering or when recording a video in real time in each sub-cell, if by user ID and password access authentication, the video information that is provided with and user ID and password are transmitted to master unit together; If by the ID and the password access authentication of relevant sub-cell, the ID and the password of the video information that is provided with and relevant sub-cell transmitted to master unit.
Another embodiment is provided with pre-ordering or when recording a video in real time in each unit, can select records a video is provided with the unit identity code or the user identification code of picture.Here, also the identification code and the user identification code of unit all can be selected, also can be selected wherein any one.At this moment, the identification code of selection is included in the video information.
Simultaneously, the present invention also can select class information when video recording is set.
For convenience of explanation, the present invention will utilize grade (grade 1) without limits, forbid editor/deletion grade (grade 2), forbid that 3 class informations of playback level (grade 3) are used as example and are illustrated.
Here, class information can be the class information that is provided with arbitrarily as top user, also can be the clear and definite class information of indication in the satellite broadcasting grade specification, can also be the class information that is provided with of user with satellite broadcasting grade specification in the combination of the class information of clearly indicating.Because the practitioner of correlative technology field can carry out certain change to this, so not only be confined to this.
Fig. 3 is for being provided with the accompanying drawing of an example of pre-ordering picture according to the present invention.The unit option is as in the program that will record a video, and (that is, master unit and each sub-cell) project can show the unit identity code of distinguishing each unit in the unit of selection additional identification code.Here, each unit identity code can be provided with by the user, also can be that system is provided with automatically.For instance, the user can be provided with the sub-cell that is in the child room by child's name and house title, perhaps, also can ID be set by the unit identity code of correlation unit in the system.
Simultaneously, the grade option is in the program of video recording, the project of the grade that selection will add.
Top Fig. 3 is according to the unit with a identification code, and grade is to forbid playing, and channel is No. 201, and the date is June 12, and the time is points in afternoons 5, and video time is 10 minutes, repeats once to be provided with example.
Also have, under the situation of video recording in real time, in the unit of Set For Current video recording, with the ID of access authentication, such as the identification code of correlation unit or user identification code send master unit to real-time video information, at this time, can select grade.
On the one hand, examine the video information of master unit oneself and the video information of each sub-cell, if arrived the video time that master unit or any one sub-cell are provided with, the program of the predetermined channel of the video information that adjust, detection comprises video time, in the program of detection, additional packets is contained in unit identity code and the class information in the video information and stores HDD into.
That is, in HDD, shown in Fig. 4 a, the program of additional discrete cell identification code of storage and class information.In Fig. 4 a, with unit a is example, we can know that in content (contents) 1 what be provided with is " not limiting (grade 1) " grade, and what content 4 was provided with is " forbidding editor/deletion (grade 2) " grade, content 7 settings be " not limiting " (grade 1) ' grade.
Fig. 5 is according to the present invention, unit identity code and class information is appended in the program that will record a video the flow chart of video recording and playing process in HDD.In any one sub-cell of master unit and a plurality of sub-cells, in HDD, be provided with comprise will video program, the pre-ordering information (stage 501) of unit identity code, class information.At this moment, if video information is set, send the video information that is provided with to master unit in sub-cell.In master unit, store the video information and the video information that transmits of sub-cell of oneself after, carry out the comparison in cycle with the in progress information that receives from TV station and the video information of setting.Then, if to the video time that is provided with in any one video information, the predetermined channel that is provided with in then adjustment, the relevant video information of detection, additional packets is contained in unit identity code and the class information in the relevant video information in the program of detection, stores into (stage 502) among the HDD.For instance, in sub-cell B, as shown in Figure 3, if be provided with pre-ordering, send the video information that is provided with to master unit, if to points in afternoons 5 June 12, master unit is adjusted 201 channels, after the detection, (unit a) and class information (grade 3) stores HDD into to the identification code of additional sub-cell B in the program of the channel of detection.
After, in master unit or sub-cell, if the user selects to play (stage 503), the user imports the identification code (stage 504) of designating unit.Then, whether the program of confirming to have the unit identity code of input records a video among the HDD, if record a video, only needs cancellation have the grade of the program of unit identity code, and all program contents will show (stage 505) on a picture.
In program contents display frame,, then can normally play the program (stage 507) of selection if the user selects to cancel the program contents (stage 506) of the unit of grade.
On the other hand, in program contents display frame, if the program contents (stage 508) of the unit of grade is not cancelled in user's selection, then according to the class information that is provided with, selected program (stage 509) is play and is edited/delete in restriction.
Fig. 4 b is in master unit or sub-cell, after the user selects to play, under the situation of the unit of selecting to have a identification code, only cancels the program grade of unit a, the example of the program contents picture of demonstration.
Here, if the program contents that selection has a identification code can be finished normal broadcast, if the program contents that selection has b, c identification code according to the class information that is provided with in the program, will limit and play and editor/deletion.Such as among Fig. 4 b, if chosen content 5, because the content of selecting, that is, the grade of program is to forbid playing (grade 3), so can not finish broadcast.
At this moment, after selecting to play, in unit identity code input picture, if the identification code (for example, the ID of master unit and password) of input master unit, cancellation can show whole program contents after the grade of all programs of HDD storage.That is, irrelevant with grade, can normally play all programs that are stored among the HDD.This is that the identification code of master unit is set to a kind of situation that father and mother wait the main frame identification code of using.Also have, under the situation of giving user ID and password, can wait user ID and the password setting used to be the main frame identification code father and mother, in this case, can cancel the registration of all programs that are stored in HDD.Here, the main frame identification code can be set to a plurality of.
And, the user if select to play, only cancels other input unit identification code pass through the ID and password acquisition authentification of user of correlation unit in designating unit after, automatically after the grade of the program relevant of access authentication, just can show whole video program catalogues with unit identity code.This is equally applicable to obtain by ID and password according to class of subscriber the situation of authentication.
The present invention records a video by program cells identification code and the class information that will record a video are set, and other people edit arbitrarily for the program of the own video recording of keeping and prevention/and delete cells played crucial effect.
On the other hand, as another example of the present invention,, also can record a video by the program password of recording a video among the HDD is set.
That is, when choosing the program of recording a video in the HDD,, have only, just allow to choose by correctly inputing password if program is provided with password.
Fig. 6 a is that an example of the program contents of the program password of recording a video among the HDD is set.Be provided with in the picture in the video recording identical with Fig. 3, when video recording was set, the user can input password.Then, during to the program recording of the video information that is provided with password, identical password is recorded a video above adopting in HDD.
Fig. 6 a is the example that each program is inputed different passwords.The program of password is not set, such as the content 2 of b unit can be play in unit b, even do not input password, also can play.
Such as, in the program contents picture of Fig. 6 a, if user in selecting content 1 demonstrates the information that needs the input password on picture.At this moment, if the user correctly inputs the password of content 1, shown in Fig. 6 b, cancellation password, the normally program of play content 1.If, password input error, program that can not normal play content 1.
Simultaneously, also can deletion and the editing authority by the program behind the password be provided with.That is, password and grade are set in program, the situation of in HDD, recording a video.If in the supposition program of in HDD, recording a video, stored unit identity code and grade and password,, password should be inputed correctly and unit identity code can be play for this program of normal play.
Fig. 7 a is the example that the program contents of the identical password of the program of identical unit is set.
For example, shown in Fig. 7 a, if the user in the program contents picture, the information of input password just appears requiring in chosen content 1 on picture.At this moment, if the user correctly inputs the password of password a, will shown in Fig. 7 b, can normally play program (content 1, content 4, content 7) with password a.If each program all is provided with grade, in the program contents of password cancellation, will demonstrates grade be set.
Therefore, even the password cancellation has only the identification code of importing correlation unit once more can normally play relevant program.For example, in order to play the program relevant, need correctly input the identification code of password a and unit a with content 1.
On the other hand, the present invention during to program recording, can also can replace the unit identity code storage with user identification code according to actual user's difference according to the memory cell identification code as embodiment simultaneously in HDD.
