Below, we are with reference to description of drawings example of the present invention.
Fig. 1 is the block diagram of an example of the formation of the expression Tai Nei system that is suitable for the digital broadcast signal multichannel dispensing device relevant with the present invention.As shown in Figure 1, system according to the present invention has encoder (ENC) 11,12, multiplexer (MUX) 13, coding multichannel control device (EMC) 14, data broadcasting dispensing device 15, automatic program transmission control device (APC) 16, platform internal clock 17, and data server (DS) 18.
The output of 13 pairs of each encoders 11,12 of multiplexer and the transmission stream of exporting from data broadcasting dispensing device 15 that is used for data broadcasting carry out demultiplexing, send as the transmission stream (TS) that is used to send.Again, the information according to from 14 outputs of coding multichannel control device generates PMT (Program Map Table (flowchart)), and the data of PAT (ProgramAssociation Table (program contingency table)) etc., multichannel change into the transmission stream that is used to send.
Coding multichannel control device 14 is according to the indication information that provides from automatic program transmission control device 16, broadcasting schedule data and encoder 11,12 and multiplexer 13 are controlled with the moment of weaving into that platform internal clock 17 is measured.In addition, at PMT, among the PAT, comprise and be illustrated in about the information of program and transmit the information that whether comprises the data that are used for data broadcasting in the stream.
Data broadcasting dispensing device 15 is according to the indication information that provides from automatic program transmission control device 16, and the TS that is used for data broadcasting of constructed in groups is sent to multiplexer 13.
Automatic program transmission control device 16 is weaved into the moment to coding multichannel control device 14 and data broadcasting dispensing device 15 transmission indication informations according to the broadcasting schedule data that provide from data server 18 with what platform internal clock 17 was measured, coding multichannel processing to coding multichannel control device 14 is controlled, and the transmission of data broadcast transmitting device 15 is handled controlled again.
Fig. 2 is the block diagram of the concrete formation of the above-mentioned multiplexer 13 of expression.As shown in Figure 2, multiplexer 13 has packet filtering apparatus 131,132,133, buffer 1341～134n, 1345～135m, 1361～136p, selector 137, counter 138, multichannel processing unit 139, multiway decision device 140, send cycle management device 141, TS generates buffer 142 and buffer monitoring arrangement 143.
Packet filtering apparatus 133 is kept at other information among each buffer 1351～135m with decided number respectively according to the TS grouping row that are used for data broadcasting that separate from the packet priority sequential bits of data server 18 notices from 15 outputs of data broadcasting dispensing device.
138 pairs of packet count from selector 137 outputs of counter are counted, and when less than fixed number, will export in the puppet grouping insertion transmission stream.
139 couples of each buffer 1341～134n of multichannel processing unit, 1345～135m, the packet content of 1361～136p monitors, this is monitored that the result sends to multiway decision device 140, and read according to the result of determination of multiway decision device 140 and to be kept at each buffer 1341～134n, 1345～135m, the grouping of 1361～136p is also controlled.In addition, in result of determination, comprise the transmission rate of the transmission stream (TS) that is used for television broadcasting.
TS generates buffer 142 and preserves the grouping row that for example arrive from coding multichannel control device 14 process LAN with decided number, under the control of multichannel processing unit 139, outputs to selector 137.In addition, packet count and the packet content that is kept in the TS generation buffer 142 by 141 pairs in transmission cycle management device manages.
143 pairs of buffer monitoring arrangements are kept at each buffer 1341～134n, 1345～135m, and the packet count among 1361～136p monitors.
Secondly, our following explanation work of treatment in the above-described configuration.
At first, the transmission band of data broadcasting, as shown in Figure 3, the remaining frequency band in the frequency band that use is used in the image/sound of television program has become the basic conception of transmission.Because the image in digital broadcasting/sound adopts the compression coding technology of MPEG2 regulation, so the frequency band that is used for television broadcasting is along with visual scene change.
Now, because be that target transmits the TS that is used for data broadcasting with fixing bit rate with frequency band in advance, so when the size of code minimizing of image/sound, the frequency band what demultiplexing does not all have takes place invalidly from the maximum code amount remainder of image/sound.
Therefore, in this example, to be listed as intactly input multiplexer 13 from the data broadcasting TS grouping of data broadcasting dispensing device 15 outputs, in multiplexer 13, carry out being used for accordingly the transmission control of the TS grouping row of data broadcasting with the frequency band change.At this moment appearance such as Fig. 4 (a) of transmission control, (b) shown in.
Fig. 4 (a) presentation code device 11,12 output, the output of Fig. 4 (b) expression data broadcasting dispensing device 15, the output of Fig. 4 (c) expression multiplexer 13, in each figure, A represents to be used for the TS grouping of television broadcasting, B represents puppet grouping not, C is used to represent the TS grouping of the data broadcasting of high precedence bit, and D represents that the TS grouping that is used for data broadcasting that precedence bit is lower than C, E represent the TS grouping of demultiplexing expeditiously.
Here, in multiplexer 13, future, the own coding device 11,12 the TS grouping row input packet filtering apparatus 131 that is used for television broadcasting, after being separated into the TS grouping and pseudo-grouping that is used for television broadcasting, the TS grouping that only will be used for television broadcasting is kept at each buffer 1341～134n in turn with decided number respectively.Be kept at the supervision that grouping among each buffer 1341～134n is subjected to multichannel processing unit 139 respectively, and this is monitored result notification multiway decision device 140.
Again, in multiplexer 13, to be input to packet filtering apparatus 133 from the TS grouping row that are used for data broadcasting of data broadcasting dispensing device 15, for example be separated into the TS grouping that is used for data broadcasting with the 1st of television program interlock, with independently the 2nd TS grouping that is used for data broadcasting of television program, the grouping of DII section, after the grouping of event message section, according to precedence bit from data server 18 notice, with the packets in sequence of deciding number be kept among each buffer 1361～136p.Be kept at the supervision that grouping among each buffer 1361～136p is subjected to multichannel processing unit 139 respectively, and this is monitored result notification multiway decision device 140.
In the time will giving multichannel processing unit 139 from the result of determination of multiway decision device 140, multichannel processing unit 139 is judged the transmission rate of the TS that is used for television broadcasting from this result of determination, according to this result of determination, read the TS grouping that is used for television broadcasting in turn from each output buffer 1341～134n, give selector 137.
And, in multichannel processing unit 139, during should reading pseudo-grouping, read the TS grouping that comprises PSI/SI from each buffer 1345～135m, and selectively read the 1st TS that is used for data broadcasting according to precedence bit from each buffer 1361～136p and divide into groups, the 2nd is used for the TS grouping of data broadcasting, reads the grouping of DII section, the grouping of event message section gives selector 137.So, be listed as from the grouping shown in demultiplexing device 135 output maps 4 (c).
Therefore, even if the size of code of image/sound that can television program can not influence like that transmission when changing to maximum yet, transmit the data of the high data broadcast program of the precedence bit of visual scene of 1 scene etc. of for example subsidiary general knowledge quiz problem and drama.
When the above-mentioned transmission rate that is used for the TS of television broadcasting surpass during fixed threshold value, for example deposit the low TS grouping that is used for data broadcasting of precedence bit in the continuation of insurance of buffer 1362 relayings.Frequent amount of savings notification buffer monitoring arrangement 143 with this buffer 1362.The amount of savings of buffer monitoring arrangement 143 look aside buffers 1362 is when the buffer information notification data broadcast transmitting device 15 that surpasses institute quantitatively the time, will go off the air the TS grouping that is used for data broadcasting.
As mentioned above in above-mentioned example, packet filtering apparatus 131～133 is set, buffer 1341～134n, 1351～135m, 1361～136p, at packet filtering apparatus 131, the TS that will be used for television broadcasting is separated into TS grouping and the pseudo-grouping that is used for television broadcasting, and the TS grouping that wherein only will be used for television broadcasting is kept at buffer 1341～134n respectively.Again, at packet filtering apparatus 133, the TS that will be used for data broadcasting is separated into the 1st TS that is used for data broadcasting and divides into groups, the 2nd is used for the TS grouping of data broadcasting, after grouping of DII section and the grouping of event message section, the groupings that each is different are kept among buffer 1361～136p.And, at multichannel processing unit 139, transmission rate with the TS that is used for television broadcasting is read the TS grouping that is used for television broadcasting in turn from buffer 1341～134n, give selector 137, and during should inserting pseudo-grouping, read the grouping of DII section from buffer 1361～136p, the grouping of event message section, give selector 137, and divide into groups, give selector 137 with high the 1st and the 2nd TS that is used for data broadcasting that calls over of precedence bit.
Thereby, even if be used for the transmission rate of the TS of television broadcasting surpass fixed threshold value, also can be change into the TS that is used to send like that to the high TS grouping that is used for data broadcasting of major general's precedence bit and the grouping of DII section and event message section grouping multichannel more accordingly, carry out and the corresponding optimal data transmission of the change of transmission rate.By effectively utilizing the frequency band that is used for data broadcasting limited in the broadcast band, can transmit the high TS grouping that is used for data broadcasting of precedence bit expeditiously again.
Again, when the frequency band occupation rate that is used for television broadcasting shows hour, because also can promptly see and hear data broadcast program for even if the user at any time begins to receive, can in the frequency band that may transmit, launch whole programs, so as prior art,, can in frequency band, not waste by being fixed for the broadcast band of data broadcasting, therefore, can carry out transmitting with the corresponding optimal data of the change of frequency band.That is, can improve all effective rates of utilization of broadcast band.
Further, because the frequency band occupation rate that is used for television broadcasting surpass the state of fixed threshold value, amount of savings by 136 pairs of output buffers 1341～1344 of buffer monitoring arrangement monitors, when this amount of savings is quantitative above institute, the control that stops for data broadcasting dispensing device 15 implementation data broadcast packe, so do not need to change output buffer 1341～1344 into jumbo buffer, thereby can lower the processing load of multiplexer 13, and cheap device can be provided.
Again, in above-mentioned example, because at multichannel processing unit 139, during should inserting pseudo-grouping, also read the PSI/SI grouping that is kept among buffer 1351～135m, give selector 137, so be not subjected to the influence of broadcast band change, for example when generation information is changed and in the situation in program when change etc., can change into the TS that is used to send and launch changing the corresponding PSI/SI multichannel of dividing into groups with this transposing and program.
In addition, the present invention is not limited to above-mentioned example.For example, in above-mentioned example, when the transmission rate that is used for television broadcasting surpass during fixed threshold value, send the high data broadcasting grouping of precedence bit, DII section grouping and the grouping of event message section, the data broadcasting grouping and the DII section of high precedence bit are divided into groups but also can only send.Use the event message section not necessarily to need relevant with content.Again, can set fixed frequency band arbitrarily, also can often launch precedence bit by setting is 1,2, and 3 data broadcasting grouping.
Again, in above-mentioned example, packet filtering apparatus 133 goes out the grouping of the 1st data broadcasting according to the information of weaving into from data server 18 from the data separating that is used for data broadcasting, the grouping of the 2nd data broadcasting, the grouping of DII section and the grouping of event message section.But, be not limited thereto, also can according to be included in the data that are used for data broadcasting decide the control information grouping, go out the grouping of the 1st data broadcasting from the data separating that is used for data broadcasting, the grouping of the 2nd data broadcasting, the grouping of DII section and the grouping of event message section.
Further, in above-mentioned example, we will be illustrated as object by the fixing television broadcasting system that receives service, but for example also go for to the broadcast system of the moving body that uses portable receiving terminal with to the broadcast system of portable terminal.Also go for utilizing the computer system of special-purpose gauze and INTERNET (internet) again.
Other, is about the formation of Tai Nei system, the kind of multiplexer and formation thereof, the multichannel control sequence of the TS grouping in multiplexer, the content of TS grouping also can be carried out all distortion in the scope that does not break away from main idea of the present invention.
As above stated in detail, if according to the present invention, then can provide when broadcast band changes, also can be neatly and expeditiously that precedence bit is the high data multiplex that is used for data broadcasting change into the digital broadcast signal multichannel dispensing device that television broadcasting signal is broadcasted.
