As mentioned above, catch the image of printing, can permit to catch and print or control it and catch printing for the permission in the image of broadcasting.Thus, program control document only can be caught when printing during looking the hearer and having pointed out existing, and therefore, there is no need to carry out actual print management, and this way makes control become simple, simultaneously, can also be unit execute permission, objectionable control with the frame.Can in broadcasting process, point out the demonstration permission to catch the image of printing.Thus, on one side on one side the audiovisual broadcast program is carried out and caught printing, thereby can improve convenience.
As mentioned above, in the 1st execution mode, can from the SI data, get access to and be attached to the data of catching in the image.Owing to the satellite information of SI information as program data is transmitted, therefore, on capacity, also be restricted, so, do not transmit the details of each scene etc., and only at the information of catching image additional program name degree.Situation when therefore, explanation has added more multidata in the 2nd execution mode.
(the 2nd execution mode)
Next, just the broadcast system of the 2nd execution mode describes according to the present invention.In the 2nd execution mode, describe having used the example under the situation of dividing segment metadata.With regard to the structure of device,, therefore omit its explanation because it is identical to the 1st execution mode of Fig. 5 with Fig. 1.So-called metadata is the general name with the corresponding attribute information of data.
In international standardizing bodies that is called as TV Anytime Forum (hereinafter referred to as TVAF) and ARIB etc., discuss for metadata as video and audio program.In addition, in the record scheme of metadata MPEG7 is arranged, above-mentioned TVAF also discusses it as the basis.
That is, there are 3 kinds in this in the metadata related with program.First is a content metadata.This metadata is corresponding to program integral body, recorded and narrated exercise question, kind, summary, impresario of program etc.In broadcast data, include and the identical information that from the SI information that is transmitted, obtains.The 2nd is example (instance) metadata.
This metadata has been recorded and narrated contents such as the valid expiration date, charge information, other service regeulations of recipient's information, the reproduction of program.The 3rd kind is the branch segment metadata.This minute, segment metadata was to be the record document of unit with the scene, and it has recorded and narrated the information of the special scenes (segmentation) that is used for visiting or to operate the video/audio of program, it and program simultaneously or stagger the time (at other times) be sent to receiving terminal.
By these data of suitable control, thereby can executive summary reproduce, classification is unifiedly reproduced, this reproductions of multiway is this and surpassed the reconstructing of the various corresponding video/audios of audiovisual mode of program scope.Also can utilize metadata to carry out scene retrieval etc.In addition also has consumer's metadata.This metadata is different with other metadata, does not attach in program but produces at receiving terminal, and therefore, it is made of this content of audiovisual resume, taste information of looking the hearer, and carries out under the situation of program commending etc. and be used looking the hearer at the TV device.
Represented structure among Figure 16 by the branch segment metadata of the 2nd execution mode use.This minute, the structure of segment metadata followed TVAF, MPEG7 standard.
As shown in figure 16, the information with reference to program (CRID) of dividing segment metadata to have to become the object that has formed scene, this minute segment metadata the scene title, scene abstract, the time started of scene, the duration of scene of segmentation ID, this scene, in addition, also have free keywords.In the 2nd execution mode, recorded and narrated and caught the printing permission flag, as a kind of information wherein.As other free keywords, photography place, impresario, brief introduction (profile), bent name etc. been have also have been recorded and narrated.
In the 2nd execution mode, for the program that is received, as shown in figure 17, segmentation ID is recorded and narrated in minute segment metadata the data of 6 scenes from S001 to S006.These minutes, segment metadata at first generated by the editing saving person, was saved to afterwards in the Internet Server portion 2112 of above-mentioned broadcaster 21.
In addition, when program receiving, in additional information preservation portion 2103, preserve the program control document that comprises the control script and catch printing control information, wherein, the control script is a control script of downloading above-mentioned minute segment metadata from Internet Server 2112, catch printing control information and be used for the control method item of catching printing control information shown in Figure 7 be set to " the stream permission flag; Divide segment metadata " structure.
Next, use Figure 13 and Figure 19 that the operation of relevant the 2nd execution mode is described.That is, as shown in figure 13, at first, establish identically with the 1st execution mode, arriving program after the zero hour, utilize the output control part 2121 of broadcaster 21, the synthetic program control data that comprises program data and permission type information begins to send afterwards.Afterwards, in step ST2101, utilize the data broadcasting control part 1191a of the TV device 11 received this program control data, establish identically, detect the program control data of above-mentioned program with the 1st execution mode.
Afterwards, carry out this program analysis, and detect: the control script that comprises the download instruction of above-mentioned minute segment metadata; And the item of control method is set to " stream Xu Kebiaozhi ﹠amp; Divide segment metadata " catch printing control information.
Afterwards, in step UST2102, to the 1191b of acquisition control portion inquiry TV device 11 whether with catch print corresponding.
Simultaneously, detected the download instruction of branch segment metadata originally, and controlled Internet connection portion 1171 according to control pin.Afterwards, be connected to Internet Server portion 2112, download branch segment metadata shown in Figure 17, and it is kept in the memory section 1151.
Afterwards, to step ST2116, carry out and the 1st execution mode identical operations, as for the prompting of looking the hearer from step ST2104 shown in Figure 13.
On the other hand, Figure 19 be illustrated in permission catch printing during in, supress operating process under the situation of the catching press-button that will control by looking the hearer.In step UST2201, utilize the 1191b of acquisition control portion that catching by sending a notice from other control parts 1191e is provided.Afterwards, identical with the 1st execution mode, in step ST2202, interrupting in the writing of acquisition control portion 1135, keeping for example is stipulated time of 5 seconds, afterwards, the writing of interrupt trap buffer storage 1136.
Afterwards, among the step ST2203 in Figure 19, the catching in the interim storage area of data of memory section 1151 will be kept between these data and trapping period.Represented among Figure 18 in the TV device 11 in the 1st execution mode, preserve the content of catching file when catching data.Extract scene name, scene abstract, shooting place and actor information (name, brief introduction etc.), bent information (bent name, write words, composer etc.) the branch segment metadata of the correspondence when catching image, these information are saved to catching the part of file as other information.
Afterwards, in step ST5401, establish at being independent variable, the instruction of sending the inquiry capturing information between the trapping period of data broadcasting control part 11191a.
For sending of this inquiry instruction, in step ST5402, data broadcasting control part 1191a reads and retrieves from memory section 1151a from outside the programm name between trapping period, also reads and retrieve the branch segment metadata of corresponding time.Afterwards, permission printing sign, scene name, shooting place, performer, brief introduction, the bent name with permission type information and branch segment metadata returns to the 1191b of acquisition control portion.
Next, in step ST2211, if the printing permission flag of the capturing information that is returned is for the permission printing, then in step ST2212, whether whether the 1191b of acquisition control portion is by the GUI picture shown in the displayed map 12A, thereby catch and finish and printable to looking hearer's notice.In notice, in step ST2213, in the demonstration of this GUI picture, urge and look the hearer and select will begin in a minute printings ("Yes" button), still select preservation to catch data (" preservation " button).
Identical in the operation of having carried out after selecting to begin to print with the step ST2212 shown in Figure 14 operation afterwards of illustrated mistake in the 1st execution mode.
Promptly, in step ST2213, after supressing save button, forward step ST2241 to, as shown in figure 18, in catching data except between program names, trapping period, the permission type information, the branch segment metadata that provides by data broadcasting control part 1191a also has been provided, afterwards, it is kept in the data preservation portion 1182.
Next, being located at the file of preserving among the step ST2241 can be shown once more, can carry out licensed printed contents during this and print.The data of catching of this preservation are read once more, and the display frame of demonstration, the preservation capturing visual inventory when printing is shown in Figure 20.Figure 15 B that illustrated in Figure 20 and the 1st execution mode is corresponding.
Catch, when preserving owing to preserved content shown in Figure 180, therefore, in the capturing visual inventory, also display program name and catching constantly not, and the displayed scene name, show performer, bent name etc. at the image marge.
Owing to pass through to carry out above the demonstration, look the hearer and be easy to hold the image that is captured, therefore, can print the image of wishing printing at an easy rate.
So, identical with the 1st execution mode in the image that can utilize this inventory to select to wish to print, executive editor, correction etc. are carried out afterwards and are printed.
More than be that still, the present invention is not limited in above-mentioned execution mode, and the various distortion of recording and narrating thought based on the present invention also can be arranged to the specifying of embodiment of the present invention.
For example, in the above-mentioned execution mode,, also can use different with it data content and display frame as required even if data content that is exemplified and display frame do not exceed example on earth yet.
In the 1st and the 2nd above-mentioned execution mode, establish the control of catching printing of execution, also can carry out the control of catching printing according to program control document according to the branch segment metadata that illustrated in the 2nd execution mode.In the case, by judge the image caught whether be in the permission of catching in the printing control information and print during, permission the duration in, thereby come execute permission/objectionable control.
Except that the operation of the 2nd execution mode side, also can utilize the program of 11 pairs of broadcasting of TV device to record a video, and after broadcasting, the branch segment metadata in the broadcaster 21 is upgraded with timing arbitrarily, when the TV device reproduces video program, can download from the broadcaster 21 in broadcasting station and divide segment metadata.By carrying out this operation, carry out when reproducing in back that program is recorded a video, can reflect up-to-date permission type information.For example, although printing is caught in permission immediately after broadcasting, but be also with good grounds situation and make the situation of print inhibit, or, become big owing to look hearer's hope, thereby be defined in certain scene, thereby prolong the valid expiration date that printing is caught in permission.Under the different situation of the Time of Day that causes broadcasting with local difference, can make this valid expiration date and the place that is broadcasted consistently carry out renewal.
Above-mentioned catching is just to carry out the situation of catching according to motion picture video to describe, but, for example, when audiovisual, caught under the situation of the data broadcasting picture displayed that comprises Figure 21, when catching image, also preserved the program control data of control display frame together, thereby can be when printing, select the capturing visual or the data broadcasting picture of display video, afterwards, carry out and print.
In the above-described embodiment, by overlapping display message in picture, thereby show the image that permitted user is printed to user prompt, but, as reminding method for user's information, there is no need necessarily to be defined as and in picture, carry out the method that shows, also can adopt additive method in addition.For example, can by or can the loud speaker in being arranged at TV set device output voice or audio frequency, or make lamp (for example indicator light) light on and off that are arranged in the device, thereby can the execute permission user print the part of program moving image, or disapprove the prompting of a part of printing the program moving image.
The data of being lifted in for example above-mentioned execution mode also can be used different with it numerical value only for example as required.
The present invention's effect in the demonstration of the moving image program that is applied to a part of moving image of only licensed printing is relatively good, but also it might not be limited to the demonstration aspect of the moving image program of only licensed printing portion moving image.
