Embodiment
Below, with reference to accompanying drawing, the embodiment of the invention is elaborated.
Fig. 2 is the audiovisual grade that utilization of the present invention constitutes by image and level of sound signal type system, the formation block diagram of controlling by image and level of sound signal type receive-transmit system.
As shown in Figure 2, it is to be made of following structure that the present invention utilizes the receive-transmit system of image and level of sound signal type: for violence, selected scene and incorrect language (rumors, humiliate swear at people, the local dialect etc.) etc. audiovisual limit the broadcast singal of grade, when not changing whole plot structure, selected scene is made into many parts by the grade type, and for sending the sending part that the various images that are made into by the grade type and voice signal are provided with; From the grade type of press image and voice signal that sending part transmits, find out image and voice signal below the broadcast singal grade that the user sets, and the acceptance division that is provided with hypograph and voice signal for output level.
Here, sending part is the broadcasting station 10 of broadcasting after being equivalent to programme usually; And acceptance division is the system that is equivalent to by by image and level of sound signal type constitution, the digital television 20 that the audiovisual grade is controlled.
And, sending part, as the broadcasting station is to be made of following structure: limit level signal if comprise audiovisual such as violence, selected scene and incorrect language in the broadcast singal, when then not changing whole plot structure, for to corresponding scene by the grade type be divided into image stream and sound stream make and be provided with by grade type program making portion 24; To can not only in a channel, transmitting an image and sound by image stream and the sound stream that is made into by grade type program making portion 24, and in the scope that transfer rate allows, many image stream and sound stream can be transmitted together, it is controlled and the broadcasting station control part 27 that is provided with.
And acceptance division is to be made of following structure as digital television set: the key input part 21 that the user is provided with audiovisual material by various function keys; Not only control transmit each component part of signal by key input part 21, and, if sending part is to being suitable for the identical scene by audiovisual grade type, transmit after constituting by many images and voice signal, then find out and be suitable for corresponding image and voice signal, and export for image and the voice signal found out, it is controlled and the control part 22 that is provided with; Pass through the storage part 23 that control part 22 interim memory images and voice signal are provided with in order to need; In order to show the display part 25 that is provided with by the image of grade shunting by control part 22; And the audio portion 26 that is provided with for the voice signal of exporting by control part 22 output by the grade shunting.
Here, digital television broadcasting normally not only transmits 1 image in a channel, but transmit many images, owing in the scope that its speed allows, can transmit simultaneously together to many images, therefore, high definition HD (High Definition) television set utilizes the Packet Identifier PID (PacketIDentifier, not shown) that comprises at head portion usually for separating the image that is transmitted in being transmitted the structure of image.
And, single-definition SD (Standard Definition) television set represents that in a channel audiovisual grade data package draws together a plurality of, and a plurality of data comprise image/video Packet Identifier PID (Video Packet IDentifier), audio pack identifier PID (Audio PacketIDentifier) separately by each grade type, and perhaps a plurality of data are to take all factors into consideration constituting by grade type Packet Identifier of image and voice signal.
Particularly, the grade type of pressing image and voice signal that acceptance division transmits sending part not only to the differentiation of image and voice signal, and for the differentiation of level of signal, can be worked out Packet Identifier (PID) by different numberings usually.
Because above-mentioned formation of the present invention, if because of the reasons such as use of selected, violence or incorrect language need limit the audiovisual grade, then all families can not press grade audiovisual TV (TV) together in conventional art, whole in the present invention outline does not have under the situation of much variations, and all families can be suitable for the audiovisual of carrying out of user gradation together.
Fig. 3 is that audiovisual limits grade control procedure flow chart in the system of Fig. 2.
At first, if comprise violence that audiovisual limits grade, selected or incorrect language etc. in the broadcast singal that the broadcasting station sends, though then whole plot structure does not have much variations, but comprise the scene that audiovisual limits level signal, be divided into many parts by the grade type and make (S201).
After, will transmit (S202) by various images and the voice signal that the grade type is made.
Therefore, at the television receiver end, whether user's decision is set audiovisual to the signal that is transmitted and is limited grade.If the user sets audiovisual and limits grade, the grade that will set according to the user of digital television is then found out image and voice signal and according to its grade output image and voice signal (S203).
Here, what is called is suitable for constituting broadcast singal by grade and is: limit grade if the scene that the lover falls in love is set at audiovisual, then for the audiovisual user below the junior middle school student, the scene that the lover falls in love is set at the lover and shakes hands; For the audiovisual user below the middle high school student, the scene that the lover falls in love is set at the lover and kisses each other; For the adult audiovisual user more than the university student, it is warmly in love each other that the scene that the lover falls in love is set at the lover; And constitute by the sound accompaniment that is suitable for various scenes, be suitable for constituting in turn of audiovisual grade thereby can not change under the situation of whole outline.
And, if setting audiovisual, the user limits grade, then the broadcast singal input rank is judged; Otherwise in statu quo export the image and the voice signal of broadcasting.
, there are many here if satisfy the program that audiovisual that the user sets limits grade, the high program of then first comparatively speaking display level, but preferentially show any grade this is relevant with user's setting in advance.
And, comprise audiovisual qualification signal if exist, then the grade of setting according to the user is come image and the voice signal below the retrieval user setting grade, and the image and the voice signal of retrieval are exported.
, in the program that broadcasting transmits, show preferentially that usually audiovisual limits the high signal of grade though set here, this mainly is to set relevant with prior user.
Fig. 4 is that audiovisual limits grade control procedure the 1st flow chart in the system of Fig. 2.
At first, the control part 22 (with reference to Fig. 2) of digital television will periodically detect the user and whether set audiovisual qualification grade (S301).
Here, set audiovisual the user and limit before the grade, user's identification is generally included the User Recognition stages such as using identifier (ID) and password (Password), fingerprint recognition, identification.
If the user does not set audiovisual and limits grade, then image and the voice signal with broadcasting in statu quo outputs in screen and the loud speaker, thereby can make user's audiovisual material (S305); If the user sets audiovisual and limits grade, then the broadcast singal input rank is judged (S302).
Here, so-called broadcast singal input rank is meant with the broadcasting station broadcast singal, the grade that shows on the screen display (OSD) of user scope that can audiovisual.
The broadcast singal input rank is to set separately as benchmark with image or the language that uses, also can take all factors into consideration image and use language to set.
After the broadcast singal input rank differentiated, whether the broadcast singal of current broadcast is comprised audiovisual that the user sets limit level signal and detect (S303).
Suppose, it is that the user of audiovisual below 12 years old imports or selects that the user limits level setting with audiovisual, then in current in progress broadcast singal, comprise the inappropriate scene of the user of audiovisual below 12 years old (that is, comprising the signal that audiovisual limits grade) and detect whether existing.
Here, comprise the signal that audiovisual limits grade if exist, then owing to transmit the differential back formation program that carries out that is suitable for its grade in advance in the broadcasting station, therefore the control part 22 (with reference to Fig. 2) of Digital Television will constitute in the various images of identical scene and sound stream of program the differential back that is suitable for above-mentioned grade, the grade of setting according to the user is found out the user and is set image and sound stream (S304) below the grade, and comes output image and voice signal (S306) according to its grade.
But, do not limit level signal if comprise audiovisual in current television set (TV) broadcast singal, then the program below the grade of setting by the user is judged as the grade that all audiovisual users can audiovisual, therefore image and the voice signal that the broadcasting station is transmitted in statu quo exported (S305).
The present invention is the same at the virgin locking device (V-CHIP) of above-mentioned analog signal, if the user does not set grade, the scene that then broadcasting station will corresponding part (violence, selected etc.), and after using language to make by the grade type, identical scene is transmitted with many images; Be suitable for corresponding image and voice signal and in TV (TV) receiver, find out, and image and the voice signal found out are exported.Therefore, by program that can not audiovisual in the grade type TV machine (TV), also the grade that is suitable for the audiovisual user with identical outline is carried out audiovisual existing.
Fig. 5 is that audiovisual limits grade control procedure the 2nd flow chart in the system of Fig. 2.
As shown in FIG., sending or receiving terminal, according to age-based type or press the benchmark of content type, setting audiovisual qualification grade separately; Or in certain part, can set (S501).
At transmitting terminal, each grade intrinsic information that expression is set above comprises that Fig. 6 b is sent in the channel (S502) together.
At receiving terminal, limit grade and judge (S503) whether setting audiovisual, if setting audiovisual, judged result limits grade, then carry out in the high data of data middle grade rank that are transmitted, show output image and sound (S508).But can change according to the setting situation.
In addition, limit grade if set audiovisual at receiving terminal, after whether the audiovisual of then reading setting limits grade (S504) and confirms to exist audiovisual to limit grade, detect the user who whether has receiving terminal set the following data of grade (S505, S506).
Export the data of setting grade corresponding to the user according to testing result.There are many if satisfy the data that the user sets grade, then high data of output level rank therein.But the setting situation can be different, or the opposite multiple situation (S507) that also can exist that reaches.
Fig. 6 a and Fig. 6 b are that the present invention transmits and the picture example schematic by image and sound stream grade type.
Shown in Fig. 6 a, the Digital Television great advantage is to have flexibility (Flexibility), and utilizes data compression technique to realize high definition TV of high-quality screen off grade (HDTV) or multichannel standard definition television (SDTV).
Here, digital television broadcasting normally not only transmits 1 image in a channel, and transmit a plurality of images simultaneously, owing to have in the scope that speed allows the feature that can transmit simultaneously together many images, therefore, for distinguishing the image that transmits with many data, the Packet Identifier PID (Packet Identifier) that utilizes the head portion of image to comprise usually.
And, single-definition SD (Standard Definition) television set represents that in a channel audiovisual grade data package draws together a plurality ofly, and a plurality of data comprise separately that by each grade type image/video Packet Identifier PID (Video Packet Identifier), audio pack identifier PID (Audio PacketIdentifier) constitute.
And Digital Television is not only to TV (TV) signal, but also can carry out diversified Additional Services.
Shown in Fig. 6 b, the present invention utilizes above-mentioned Digital Television characteristic, virgin locking device (V-Chip) as above-mentioned analog signal, if the user does not set grade, the benchmark of conduct that then broadcasting station will corresponding part (violence, selected or use language etc.) is made (thick, thicker a little a little) by the grade type, and, be sent in a plurality of images and the voice signal with identical scene with after the voice signal of correspondence is made therewith.Be suitable for corresponding image and voice signal and in TV (TV) receiver, find out, and image and the voice signal found out are exported.
In a channel, comprising the data of representing many video level, and its data are to comprise image and sound programme identification PID by the grade type to constitute.
For example, the audiovisual grade supposition as TV (TV) drama of Fig. 6 b is divided into: the following audiovisual user of junior middle school student is set at the A grade; The middle following audiovisual user of high school student is set at the B grade; The above audiovisual user of university student is set at the C grade.
In the formation of whole drama,, this scene is made by each grade type if lover's scene in love does not then change whole outline and constitutes simultaneously for the audiovisual of setting limits grade.
That is, for just being audiovisual user below the student, as the grade a-signal, lover's scene of shaking hands; For the audiovisual user below the middle high school student, as grade B signal, lover's scene of kissing each other; For the adult audiovisual user more than the university student, as grade C lover scene warmly in love each other, in content also as thick, thicker a little a little ..., and make by the high rank of grade.And, and making is suitable for separately, and the sound accompaniment of image forms in turn.
Digital Television (TV) receiver to the broadcasting station transmit by grade types of image and voice signal, be not only for differentiation image and voice signal, and be for the differentiation to level of signal, usually the numbering of program identification PID is worked out by different needs.
For example, image/video Packet Identifier PID:0 * 21 of grade A, audio pack identifier PID:0 * 24; Image/video Packet Identifier PID:0 * 31 of grade B, audio pack identifier PID:0 * 34; Image/video Packet Identifier PID:0 * 41 of grade C, audio pack identifier PID:0 * 44, thus the PID numbering can be distinguished.
The TP connotation is to transmit bag (Transportation packet) in Fig. 6 b.
In addition, also there are selected or incorrect language etc. in recent years in music video, music program and commerce (CF) advertisement, make the audiovisual of carrying out of the grade that is suitable for the audiovisual user after therefore making by each grade type.
As above-mentioned, to selected property or violence nature scene in the broadcasting station, after the making of grade type, if identical scene is sent in a plurality of images and the voice signal, then television receiver is found out and is suitable for corresponding image and voice signal, and image and the voice signal found out exported, therefore the audiovisual user can the following content of audiovisual grade, if can not audiovisual press television set (TV) program of existing grade type, then go to be suitable for audiovisual user gradation ground and carry out audiovisual with identical outline.
