Definitions
- the present invention relates to a multiplexing apparatus and a multiplexing method for multiplexing a plurality of types of stream data such as moving image data and audio data.
- multiplexing is performed when multiple types of stream data such as moving image data and audio data are recorded on a recording medium such as a disk or sent out on a transmission path.
- a buffer for temporarily storing stream data that has been generated (encoded) or transmitted is temporarily stored, and each stream data is stored in an amount that can be multiplexed. There is something to multiplex.
- the first stream data (for example, moving image data) is multiplexed every time it is accumulated in the buffer by an amount that can be multiplexed, while the second stream data (for example, audio data).
- the second stream corresponding to the first stream data (to be reproduced at the same time) at the time of multiplexing the first stream data is not immediately multiplexed even if the amount that can be multiplexed is accumulated.
- the size of the buffer required for the multiplexing device can be kept small. Therefore, the multiplexing position of the moving image data and audio data to be reproduced at the same time tends to be separated. For this reason, the size of the buffer required for the playback device that plays back the multiplexed data increases.
- the virtual buffer fullness must be small. Since the buffer is not multiplexed and the actual buffer fullness continues to increase, the buffer size cannot always be reduced.
- the present invention has been made in view of the above points, and it is possible to easily reduce the buffer size and to make the multiplexed position of the stream data to be reproduced at the same time close to each other in the multiplexed data.
- the purpose is to be.
- An apparatus for multiplexing stream data includes: A multiplexing device for multiplexing a plurality of types of stream data, A buffer memory for temporarily storing each stream data, A multiplexing unit that multiplexes the stream data stored in each buffer memory; A multiplexing control unit that controls stream data to be multiplexed; With The multiplexing controller is A multiplexing reference time determined based on time information included in the stream data stored in the buffer memory; When there is a buffer memory that does not store stream data, the stream data to be multiplexed is controlled based on the predicted multiplexing time that is predicted as the multiplexing reference time for the stream data that is stored in the buffer memory later. It is characterized by that.
- the stream data to be multiplexed can be easily arranged.
- the stream data to be multiplexed can be determined even when there is unstored stream data. It is possible to multiplex quickly.
- the buffer size can be kept small, and the multiplexed position of stream data to be reproduced at the same time in the multiplexed data can be easily approached.

- FIG. 8 is a block diagram illustrating a configuration of a multiplexing device according to the fourth embodiment.
- FIG. 1 is a block diagram showing the configuration of the multiplexing apparatus according to the first embodiment of the present invention.
- the stream data to be multiplexed is, for example, audio data and video data, and the number (type) thereof is two.
- This multiplexing apparatus includes first and second stream data generation units 101 and 111, buffer memories 102 and 112, a multiplexing control unit 103, a multiplexing unit 104, and a selector 105.
- the first and second stream data generation units 101 and 111 are for generating stream data by encoding analog signals such as audio and video. It should be noted that the present invention is not limited to generating and outputting new stream data, but may be one that receives and outputs stream data transmitted by broadcasting or a network. Further, the first and second stream data generation units 101 and 111 are not necessarily provided in the multiplexing apparatus, and stream data may be directly input from the outside.
- the buffer memories 102 and 112 temporarily store the stream data input from the first and second stream data generation units 101 and 111.
- the selector 105 selects stream data stored in one of the buffer memories 102 and 112.
- the multiplexing unit 104 multiplexes the stream data selected by the selector 105 and outputs multiplexed data composed of, for example, fixed-length packets.
- the multiplexing control unit 103 controls selection by the selector 105 and multiplexing operation by the multiplexing unit 104. More specifically, for example, a multiplexing reference time indicated by time information such as a time stamp of the stream data and PCR (Program Clock Reference) for synchronizing the reproduction time included in the stream data stored in the buffer memory 102. Is used as a comparison time, and control is performed so that the first or second stream data is selected and multiplexed in the order of the comparison time, that is, in the order of the timing to be reproduced. If the buffer memory 102 is empty, a predicted multiplexing time is obtained as a multiplexing reference time for the next accumulated stream data, and the stream data to be multiplexed is determined using this as the comparison time. It is supposed to be.
- the multiplexing prediction time is, for example, an average required for the amount of first and second stream data that can be multiplexed to be accumulated in the buffer memories 102 and 112 at the multiplexing reference time of the last multiplexed stream data. It is obtained by adding time (accumulation cycle such as accumulation start cycle and accumulation completion cycle).
- the accumulation cycle is such that, for example, the first and second stream data are accumulated in the buffer memories 102 and 112 at an average constant rate (for example, encoding rate), and the multiplexed data is composed of fixed-length packets. Then, the packet length / encoding rate can be obtained.
- the multiplexing reference time of the accumulated first and second stream data (the leading stream data when a plurality of each is accumulated) is held as a comparison time, and these are compared and multiplexed in that order. Is done. As a result, the multiplexing positions of the first and second stream data to be reproduced at the same time can be multiplexed so as to be close to each other.
- the predicted multiplexing time is held as the comparison time for the second stream data, and the multiplexing reference time for the first stream data is more than this. If it is earlier, the first stream data is multiplexed, while if it is later, multiplexing is waited. Thus, in the former case, the first stream data is multiplexed without waiting until the second stream data is actually accumulated, whereas in the latter case, the second stream data is accumulated and multiplexed. Then, the first stream data is multiplexed.
- the comparison prediction time is the multiplexed prediction time, so that the newly accumulated stream data is updated to update this.
- the multiplexing reference time is obtained based on the included time information.
- the same processing is performed on the second stream data, and the accumulation in the buffer memory 112 is monitored and the comparison time is updated.
- Multiplex control (S111) First, it is determined whether or not the first stream data is stored in the buffer memory 102 in an amount that can be multiplexed. If not, monitoring is repeated until multiplexing is possible.
- the first stream data is selected by the selector 105 and multiplexed by the multiplexing unit 104.
- the same processing is performed on the second stream data, and multiplexing is performed while the comparison time is compared and updated.
- the accumulation cycle of the first stream data is 10 and the accumulation cycle of the second stream data is 4.
- the numbers in parentheses attached to the names of the stream data in FIG. 4 and below indicate the reference time of each stream data (for example, “0” of the first stream data (0)).
- the first and second stream data are multiplexed in the same manner.
- the stream data indicates two types of multiplexers.
- the present invention is not limited to this, and three or more types of multiplexers may be configured.
- it is determined whether accumulation from the empty state of the buffer memory is completed or multiplexing is completed for any of the stream data. That's fine.
- the comparison time of each stream data is compared with the comparison times of all other stream data, or at least the updated comparison time is other stream data. It may be compared with the comparison time.
- the stream data to be multiplexed is determined according to the preset priority. However, the comparison times are the same. Depending on the priority, one stream data is multiplexed if the difference is within a predetermined range even if the comparison time is late, while the other stream data has a comparison time earlier. If the difference is within a predetermined range, multiplexing may be waited. In addition, when the comparison time for comparison is the multiplexed prediction time, if the difference is within a predetermined range, multiplexing is performed, or is the comparison time for comparison the multiplexed prediction time? The predetermined range may be varied depending on how, or such control and control according to priority may be combined. Further, whether or not to multiplex may be controlled based on the buffer capacity, the accumulation amount, the type of stream data, and the like.
- the buffer control that is normally performed such as data discard at overflow or stuffing at underflow, may be variously applied as long as there is no logical contradiction.
- FIG. 5 is a block diagram showing the configuration of the multiplexing apparatus according to the second embodiment of the present invention, which differs from the configuration of FIG. 1 mainly in that it includes skip determination units 201 and 211.
- the skip determination units 201 and 211 determine that a skip has occurred and This is transmitted to the multiplexing control unit 103.
- the multiplexing control unit 103 forcibly updates the multiplexing reference time of the stream data on which the skip has occurred, for example, to the next multiplexing prediction time obtained by adding the accumulation period, and the comparison time and To do.
- the other stream data is multiplexed if the comparison time is later than the comparison time before the update in the stream data on which the skip occurs, but is earlier than the comparison time after the update. Is done.
- the buffering amount of the buffer memories 102 and 112 can be reduced. Therefore, the capacity of the buffer memories 102 and 112 can be kept small.
- FIG. 6 is a block diagram showing the configuration of the multiplexing apparatus according to the third embodiment of the present invention, which is different from the configuration of FIG. 1 mainly in that buffer monitoring units 301 and 311 are provided.
- the buffer monitoring units 301 and 311 monitor whether or not the accumulated amounts of the buffer memories 102 and 112 have reached a predetermined threshold value, and if so, the multiplexing control unit 103 determines the other stream data. For example, the comparison time is forcibly updated to the next comparison time obtained by adding the accumulation period.
- the threshold value of the accumulation amount in the buffer monitoring units 301 and 311 is two times of multiplexing.
- the second stream data (0), (4), and (8) are sequentially stored in the buffer memory 112 and multiplexed as described in the specific example of the first embodiment (FIG. 1).
- the first stream data is not input and stored in the buffer memory 102 due to the occurrence of a skip at time t10.
- the comparison time of the first stream data is not updated with the multiplexed prediction time “10”.
- the comparison time “12” in that case is later than the comparison time “10” of the first stream data.
- the second stream data is not multiplexed and remains stored in the buffer memory 112.
- the multiplexing reference time (the value set as the sequential comparison time) of the second stream data (12) (16) stored in the buffer memory 112 is earlier than the updated comparison reference time. Therefore, the data is sequentially multiplexed without waiting for the first stream data (10) to be actually input.
- the buffer memories 102 and 112 can be The capacity can be easily kept small.
- the buffer monitoring units 301 and 311 are provided to monitor the accumulated amounts of the buffer memories 102 and 112.
- the present invention is not limited to this, and the type of stream data, the capacity of the buffer, and the like In response to this, only one of the buffers may be monitored.
- the threshold value of the accumulation amount is not limited to the same for each buffer and can be set variously.
- addition value when the comparison time is forcibly updated is not limited to the above-described accumulation cycle, and may be any value that can at least reduce the accumulation amount of the buffer.
- FIG. 8 is a block diagram showing a configuration of the multiplexing apparatus according to the fourth embodiment of the present invention, which is different from the configuration of FIG. 1 mainly in that timer monitoring units 401 and 411 are provided.
- the timer monitoring units 401 and 411 have built-in timers, and notify the multiplexing control unit 103 that the stream data has not arrived when the stream data has not arrived in the buffer memories 102 and 112 for a certain period of time. To do.
- the multiplexing control unit 103 forcibly updates the comparison time of the unarrived stream data to the next comparison time.
- the stream data stored in the other buffer memories 102 and 112 can be quickly multiplexed.
- unmonitored monitoring may be performed only for one of the buffers.
- the constituent elements described in each embodiment or modification may be combined in various ways as long as it is logically possible.
- the comparison time may be updated when any of stream data generation skip, buffer memory accumulation amount increase, or stream data non-arrival occurs.
- multiplexing reference time and the multiplexing prediction time are not limited to being held as comparison times, but may be obtained, for example, as needed or referenced from accumulated stream data.
- the multiplexing device and the multiplexing method according to the present invention have an effect that the buffer size can be reduced and the multiplexing position of the stream data to be reproduced at the same time can be easily approached in the multiplexed data.
