Description

  The present invention relates to a recording / reproducing apparatus having a function of executing editing while communicating with a server via a network.

  In recent years, we have used editing functions such as creating new video data by cutting out video data shot with a video camera, digital camera, etc. in a desired section, or creating new video data by combining multiple video data. Thus, a user can create a desired video.

  However, some editing functions may be difficult to implement in a device body such as a video camera due to restrictions on memory capacity and the like. One of them is a combined editing function. As an example of combined editing, an outline of a case where stream A and stream B are combined to generate a new stream C will be described.

  In order to combine the two streams, first, the last encoded data of stream A and the first encoded data of stream B are decoded, expanded, and expanded on the memory. Next, the expanded video data can be re-encoded and encoded to be combined as one stream.

  During the above process, a memory capacity to expand the uncompressed video data at the coupling part is required at the time of re-encoding, but it cannot be realized by a mobile device such as a camera or a video camera that cannot secure a sufficient memory capacity. there were.

  On the other hand, a system has been proposed in which video from a camera is received by a server via a network and an editing function is realized on the server side (see Patent Document 1).

JP 2007-166074 A

  The prior art includes a video storage server that receives and stores video data from a camera via a network, and a video display terminal that receives and displays video data from the video storage server. For the video data stored in the server at the video display terminal, an edit list specifying the video data and the cut-out time is created and transmitted to the server. The video storage server edits and stores video data based on the received edit list.

  However, in the above-described prior art, it is necessary to transmit video data captured by the camera in advance to the video storage server, and it is necessary to follow a procedure of creating and transmitting an edit list for the video that has already been stored. Become. Therefore, it is necessary to wait in this state for the period during which captured video data is transmitted from the camera. The video data of a moving image may have a capacity of several gigabytes, and it takes a considerable time to complete transmission of the video data. In addition, if it is not possible to shift to the shooting operation during the transmission of the video data, there is a possibility that the shooting opportunity will be missed. Further, when editing, a complicated operation of selecting a video to be edited via the network and instructing editing contents is required, and it is assumed that the user's operational feeling is significantly deteriorated.

  Accordingly, an object of the present invention is to provide a recording / reproducing apparatus that efficiently edits video in cooperation with a video editing server.

  The present invention provides a recording / playback apparatus capable of transmitting and receiving predetermined information by communicating with a video editing server capable of substituting at least a part of an editing function, and information of each video to be combined in a combined editing of a plurality of videos, Means for determining whether combined editing is executed in the recording / reproducing apparatus or in the video editing server based on memory capacity of the recording / reproducing apparatus and mode information of the apparatus; and According to the determination result, the video editing server receives the combined editing command, the identification information, and the video data in the vicinity of the coupling portion of each video, and receives the video data in the vicinity of the coupling portion combined in the video editing server. The combined video data is generated by inserting the video data of the recording / reproducing apparatus based on the identification information.

  According to the present invention, it is automatically determined whether a predetermined editing function can be realized in a device such as a camera, and when the editing function is realized in cooperation with a server via a network, only necessary information is transmitted / received. Since it is processed, operability is improved. In addition, since the transition to the shooting operation can be performed simply, convenience is improved.

[Example 1]
FIG. 1 is a block diagram of a recording / reproducing apparatus 10 according to the first embodiment of the present invention. In FIG. 1, reference numeral 101 denotes an optical system such as a lens, and a zoom lens or the like can be used. Reference numeral 102 denotes an imaging unit, which includes an imaging device such as a CMOS sensor or a CCD sensor, an AD converter, and the like. A signal processing unit 103 performs processing such as conversion of the captured signal.

  A memory 106 holds video data, encoded data, control data, and the like. Reference numeral 107 denotes a graphic processing unit that generates GUI parts such as icons and characters to be superimposed on the captured image and draws them in a predetermined area of the memory 106.

  Reference numeral 108 denotes a video signal processing unit that synthesizes video data being shot obtained through the imaging optical system and a GUI component drawn by the graphic processing unit 107 and outputs the resultant to the display panel 109.

  The display panel 109 displays the video signal synthesized by the video signal processing unit 108. As the display panel, a liquid crystal panel, an organic EL panel, or the like can be used.

  An encoding processing unit 110 compresses and encodes the video data held in the memory 106 and holds it in the memory 106. At the time of reproduction, the compressed and encoded data read from the recording medium and held in the memory 106 is decoded and held in the memory 106.

  Reference numeral 111 denotes a recording / playback processing unit that performs a process of writing encoded data held in the memory 106 to the recording medium 112. In addition, a process for reading data recorded on the recording medium 112 is performed.

  Reference numeral 112 denotes a recording medium, which can be a semiconductor memory such as a flash memory or an SD card, an optical disk such as a DVD or a BD, a hard disk, or the like.

  An operation unit 104 detects an operation state of members such as buttons and switches. In a configuration in which a touch panel is pasted on the display panel 109, a touch operation with a finger or a pen on the touch panel, a movement, and the like are detected.

  Reference numeral 105 denotes an MPU (microprocessor), which can control each processing block via a control bus (not shown), performs various arithmetic processes, and controls the entire apparatus.

  Furthermore, the apparatus 10 has a plurality of modes such as a shooting mode for shooting a subject, a playback mode for browsing the shot video, and an editing mode for editing the video. The MPU 105 manages the mode information of the apparatus, and in each mode. Transition processing between control and mode is performed.

A communication processing unit 113 converts data according to a predetermined protocol and transmits / receives data to / from an external communication network by communication means such as a wireless LAN.
The recording / reproducing apparatus 10 of this embodiment is connected to a video editing server as shown in FIG. 2 via a network such as a wireless LAN, and transmits / receives video data and editing information.

  Next, the operation of the apparatus of this embodiment will be described with reference to the flowchart of FIG. In FIG. 4, the operation member of the operation unit 104 is operated in S400 to shift to the edit mode, and the combined editing is started. In S401, video data to be combined and edited is selected.

  Here, the video data selection procedure in S401 will be described. Selection of video data can be performed as shown in FIG. FIG. 5A shows a case where stream B is connected after stream A. FIG. 5B shows a case where the area A1 of the stream A and the area B1 of the stream B are cut out and connected.

  In the case of FIG. 5A, selection of video data to be combined is completed by selecting stream B after stream A and determining button 502 using an operation member (not shown) on screen 501. In FIG. 5B, an operation of cutting out the areas A1 and B1 to be combined from the stream A and the stream B is performed. As shown in a screen 505 in FIG. 5B, this sets the start point of clipping on the time axis bar 507 of the stream A. The starting point is determined by moving the pointer 506 of the time axis bar 507 by operating an operation member (not shown).

  At this time, a frame image 508 corresponding to the position of the pointer 506 is displayed at the top of the screen. As a result, the user can set the cutout start point while checking the video. When the starting point is determined, the button 502 is used to determine the starting point. Since the end point is the same operation, the description is omitted.

  For the stream B, the region B1 to be combined is determined by repeating the same procedure as described above. In S402, it is determined whether the combined editing process is executed on the server or in the apparatus. Here, if the server does not perform the combining process, the process proceeds to S404 and the combined editing is executed in the apparatus. When the combination is completed in the apparatus, the process proceeds to S411 and the combination editing is terminated.

  Here, a method for determining whether the combined editing in S402 is processed by the video editing server or in the apparatus will be described.

  First, an outline of combined editing of video data will be described with reference to FIG. FIG. 3A is a schematic diagram of two streams A and B to be combined. When combining, the last GOP (Group Of Pictures) 301 of stream A and the first GOP 302 of stream B are extracted. FIG. 3B is a schematic diagram of the GOP 301 and the GOP 302.

  When the combined editing is performed, the GOP 301 and the GOP 302 are decoded by the encoding processing unit 110 to generate the uncompressed frames 303 and 304 in FIG. Then, the GOP 305 and the GOP 306 are generated by re-encoding the uncompressed frame.

  FIG. 7 shows an outline of the re-encoding process. FIG. 7A schematically shows the buffer occupancy at the time of decoding the uncompressed frame 303 in FIG. FIG. 7B shows the buffer occupancy at the time of decoding the frame 304 in FIG. As an encoding method, MPEG2, H.264 or the like is used. A known technique such as H.264 is used.

  In FIG. 7A, video data encoded from the recording medium 112 is accumulated in a buffer at a predetermined rate. The slope α is an amount indicating the reading rate from the recording medium. The encoded data stored in the buffer is read and decoded by the encoding processing unit 110 at a predetermined interval of 1/30 seconds. The code amount shown in FIG. 7A is the amount of encoded data for one frame read to the encoding processing unit 110. When compressing and encoding video data, code amount allocation is controlled so that the upper limit V of the buffer amount is not exceeded during decoding.

  Here, FIG. 7C shows the transition of the buffer occupancy when the GOP 301 and GOP 302 of FIG. 3B are successively decoded and displayed. Decoding of GOP301 is executed at time T1, and then the process proceeds to decoding of GOP302. Here, in order to display as a continuous moving image, it is necessary to perform decoding by the encoding processing unit 110 at time T2 after 1/30 second after time T1. However, the decoding process cannot be started because the reading of the encoded data from the recording medium is not completed at the time T2. As a result, a state in which the screen is not updated while the video of the last frame of GOP 301 is displayed on the display panel 109 occurs.

  In order to avoid the above situation, the encoded GOP 301 and GOP 302 are decoded and once expanded in the memory 104, and then the encoding processing unit 110 performs the encoding process again. As a result, the code amount allocated to each frame is controlled so that the decoding process can be executed after 1/30 second of time T1, as shown in FIG.

  The re-encoded encoded data GOP 305 and GOP 306 are joined with the original encoded data as shown in FIG. 3D to generate one stream C.

  In order to perform the above-described series of processing in the apparatus, a memory capacity for developing the decoded video data is required.

One frame size of the uncompressed frame is, for example, 1920 × 1080 × 2 (bytes) = about 4 MB in the HD video YUV422 format.
Since GOP 301 and GOP 302 in FIG. 3 are composed of a total of 24 frames, the total capacity of uncompressed frames is 4 (MB) × 24 (frames) = 96 MB.
Therefore, since a large-capacity memory is required, a sufficient capacity of memory must be provided in the apparatus.
In the case of SD video, 720 × 480 × 2 (bytes) = about 700 KB
3 and GOP 301 and GOP 302 in FIG. 3 are 24 frames in total. 7 (MB) × 24 (frames) = 17 MB
Therefore, there is a high possibility that the capacity of the stream buffer during normal recording / playback will fit.

  Therefore, in the apparatus of this embodiment, when the video data to be combined in S402 in FIG. 4 is HD video, the processing for combined editing is performed in the video editing server, and in the case of SD video, it is performed in the apparatus. to decide.

  Here, whether the video is HD video or SD video is detected to determine whether the combined editing is in the apparatus or the video editing server, but it is also possible to determine by other methods.

  Another example is shown below. In the memory 106 in the apparatus, S is a capacity that can be used for developing uncompressed video data during combined editing. Next, when the number of GOP frames to be re-encoded by combined editing and the type of HD or SD video are detected, it is possible to estimate the capacity required to decode the video data and expand it in the memory as described above. This is M.

Whether combined editing is possible in the apparatus can be determined by comparing the memory capacities S and M as follows.
If S ≧ M, combined editing is possible in the device. If S <M, combined editing is not possible in the device. Based on the result of the above-mentioned size determination, combined editing is executed in the server or in the device. It may be judged. It goes without saying that a reliable determination can be made by evaluating the memory capacity M with a predetermined margin added.

  Further, in the above description, the estimation is made based on the capacity available in the memory 106, but it is also possible to use a virtual memory technique in which a part of the recording medium 112 is operated as a memory.

The description of the virtual memory system is omitted as it is realized by a known technique.
When a virtual memory is used, the capacity of the virtual memory that can be used by the recording medium 112 in addition to the memory 106 is used as the memory capacity S.

  This increases the number of cases where combined editing can be executed in the apparatus. If it is determined in S402 that combined editing is to be executed by the server, the process proceeds to S403.

  In S403, data to be transmitted to the server, such as encoded data in the vicinity of the combined portion of the two streams A and B (or a part thereof) to be combined, is prepared. When the data preparation is completed, the process proceeds to S405.

  An outline of data to be transmitted to the server prepared in S403 will be described with reference to FIG. As shown in FIG. 8A, the video data transferred to the server is the last GOP 301 of stream A and the first GOP 302 of stream B. Therefore, the management information of the stream A is analyzed by the MPU 105 and seeks to the position of the final GOP 301, and the size of the final GOP 301 is copied from the position to the memory 106.

  At the same time, management information 810 for combined editing shown in FIG. 8B is generated, “identification number” is set, and then the seek position and size values are held as “transfer GOP1 area”.

  Similarly, for stream B, the management information is analyzed, the data of GOP 302 is copied, and the position and size values are held as the “area of transfer GOP 2” of management information 810.

  Further, the following information is set and held in the management information 810 in order to synthesize the data processed by the server and generate one stream. The file name of stream A is held as “combined file name 1”. The file name of stream B is set and held as “combined file name 2”.

  When values are set for predetermined items of the management information 810, the identification numbers of the GOP 301, GOP 302 and management information 810 are prepared as data to be transferred to the server. The data format for transferring to the server can be arbitrarily determined.

  In step S403, a capacity for a stream generated by combining the original video after receiving the video data processed by the server is secured on the recording medium 112. As shown in FIG. 8C, the streams to be combined are a stream A1 that is a part of the original stream A, a stream B1 that is a part of the original stream B, and the capacities of the GOP 305 and GOP 306 that are re-encoded by the server. Is the total capacity. Therefore, the MPU 105 controls such that an area for this capacity is secured on the recording medium 112 and is not used by other processing.

  In S405, communication with the video editing server is started. In S406, it is detected whether or not the connection with the video editing server is completed. Repeat detection until connection is complete. The detection of the completion of connection may be controlled at a predetermined interval so as to reduce the processing load on the apparatus. In addition, if the completion of the connection cannot be detected even after being repeated a predetermined number of times, it is possible to notify the user as a timeout error.

  When the connection with the server is completed in S406, the process proceeds to S407, and transmission data including the GOP data prepared in S403, the identification number, and a command for instructing the server to perform combined editing is transmitted to the video editing server. When the transmission is completed, the process proceeds to S412 and the MPU 105 determines whether the apparatus power is turned off.

  When the power of the apparatus 10 is turned off during the combined editing at the server, the power off is detected in S412 of FIG. 4, and the management information 810 of FIG. 8B is recorded on the recording medium 112 in S413. , The combined editing ends.

  When the power is turned on next time, the presence / absence of the management information 810 is detected. When the management information 810 exists, the data being processed by the server exists, and communication with the server is performed to receive the data that has been combined and edited. The received data can be compared with the “identification number” of the management information 810 and combined with the corresponding stream to complete the combined editing.

  Although the case where the power is turned off is shown here, the same procedure can be used when it is desired to end the editing operation in the apparatus during the combined editing at the server. In this case, when the mode is again changed to the edit mode, the combined editing may be continued by determining the presence / absence of management information in the same manner as when the power is turned on.

  If it is determined in S412 that the power is not turned off, the process proceeds to S408. In S408, an inquiry is made as to whether the combined editing at the video editing server has been completed. Whether the combined editing is completed can be inquired using the identification information transmitted together with the video data when transmitting from the apparatus to the video editing server. The video editing server is inquired at a predetermined interval as to whether or not combined editing has been completed. If it has been completed, the process proceeds to S409.

  Here, a case where a stream is temporarily inserted in the GOP area of the combining unit so that the server can continue working in the apparatus while waiting for completion of the combined editing in S408 will be described with reference to FIG.

  9, stream A1 and stream B1 in FIG. 9A are stream data excluding the area transmitted to the video editing server shown in FIG. A stream 901 indicates data corresponding to the GOP area transmitted to the video editing server.

  FIG. 9B schematically shows video frames corresponding to the vicinity of the stream 901. However, each video frame in FIG. 9B is obtained by arranging video frames extracted from the original video at predetermined intervals.

  In the apparatus according to the present embodiment, when an image corresponding to the stream 901 being edited by the server is displayed on the screen of the display panel 109, an image indicating that the server is processing is superimposed as shown in FIG. 9B. And make it clear to the user. The superimposition of the video is performed by using the video frame for OSD (on-screen display), and by combining the video signal processing unit 108 that has drawn elements such as characters and symbols by the graphic processing unit 107. .

  In FIG. 9B, the characters “server processing” are superimposed on the video frame corresponding to the stream 901. As a result, the server can recognize that the combined editing is being performed, and can continue other editing operations.

  Further, when the editing operation is continuously performed in the apparatus while waiting for the completion of combined editing at the server in S408, it is possible to delete the stream that is the target of the combined editing. For example, when the MPU 105 detects that the stream A or the stream B shown in FIG. 8 is selected by the operation unit 104 and is instructed to be deleted, a warning is displayed on the display panel 109 that the stream is to be edited.

  When the user agrees to delete the target stream, the target stream is deleted from the recording medium 112 of the apparatus 10 and the command for supporting the identification number and the combined editing stop in FIG. .

  When the video editing server 11 receives the command, the video editing server 11 executes a predetermined process. When the combined editing stop process is completed, the video editing server 11 returns a confirmation command to the apparatus 10. The apparatus 10 can receive the confirmation command and complete the combined editing stop.

  In step S409, the video data combined and edited from the video editing server based on the identification information is received. In S410, the received video data and the original video data are connected and combined into one video data. The synthesized video data is recorded on the recording medium, and the combined editing is finished in S411.

  Here, the process of synthesizing the video data received from the server in S410 with the original video data will be described.

  As described above with reference to FIG. 3, when video data (GOP 305 and GOP 306) combined and edited by the video editing server 11 is received, stream A1, GOP 305 + GOP 306, and stream B1 are combined as shown in FIG. Create one stream.

  For this purpose, first, the stream A1 and the stream B1 are extracted. The stream A1 can be extracted by removing the transfer GOP1 area from the combined area of the file 1 using the management information 810. Stream B1 can be extracted by excluding the transfer GOP2 area from the file 2 combination area.

  By combining these three pieces of data as shown in FIG. 8C, the combined stream C shown in FIG. 3 is generated. Stream C is recorded on the recording medium 112 as a new file.

  As described above, the apparatus according to the present embodiment operates by automatically determining whether to perform combined editing in the apparatus or in the video editing server from the video data, the memory capacity, etc., so that convenience is improved. Further, it is possible to flexibly cope with power-off during server processing and termination of editing work in the apparatus.

[Example 2]
A second embodiment according to the present invention will be described below. The feature of this embodiment is that processing is switched to processing at the video editing server during combined editing in the apparatus. Another object is to reduce the load of combined editing in the apparatus by giving conditions to the processing in the video editing server. The operation will be described with reference to the flowcharts of FIGS.

  In the flowchart of FIG. 4, it is determined whether or not the server performs the combining process in S <b> 402. FIG. 6 is a flowchart relating to combined editing and switching of processing to the video editing server in the apparatus in S404.

  In step S601, combination editing in the apparatus is started. In step S <b> 602, the MPU 105 determines whether the user has operated a button or the like (not shown) of the operation unit 104 to shift to the shooting mode. If there is no request for shifting to the shooting mode, the combined editing in the apparatus is continued, and it is determined in S604 whether the combined editing is completed. If it is not completed, the process proceeds to S602 and returns to the determination of whether or not there is a shooting mode request. If the completion of combined editing is detected in S604, the flow proceeds to S614, and the combined editing is terminated.

  If there is a request for switching to the shooting mode in S602, the process proceeds to S603 and editing in the apparatus is stopped. In S604, data to be transmitted to the server is prepared as described with reference to FIG. In step S606, communication with the video editing server is started. In step S607, it is detected whether the connection with the server is completed. If the connection is confirmed, the process proceeds to step S608.

In step S608, in addition to the GOP data of the coupling unit, the identification number, and a command for instructing coupling editing, processing conditions for processing on the server side are transmitted. The processing conditions here are such that the GOP data to be transmitted and the GOP data obtained as a result of re-encoding have the same capacity. That is, in FIG.
Capacity (GOP301 + GOP302) = Capacity (GOP305 + GOP306)
It becomes.

  The GOP data re-encoded by the video editing server according to this condition can be synthesized by simply replacing the original GOP data. In addition to the re-encoded GOP data, address information indicating the position of the video frame in the GOP is acquired from the server. On the device side, the acquired GOP data is replaced, and management information for managing the stream is updated based on the address information. Only the management information corresponding to GOP 305 and GOP 306 needs to be updated in the apparatus, and the management information relating to other areas can be used as it is, so that the processing load on the apparatus side can be reduced.

  In step S609 after data transmission, the apparatus is switched to the shooting mode. In S610, it is determined whether the current mode is a shooting mode. During the shooting mode, the process stands by in S610. If it is detected that the shooting mode has been switched to another mode, the process proceeds to S611.

  In step S611, an inquiry is made as to whether processing at the video editing server is completed. If not completed, the process proceeds to S610. If it is detected that the process has been completed, the process proceeds to S612. When making an inquiry about the completion of the process to the server, the above identification number is transmitted to the server, and the server inquires whether the process has been completed based on the identification number.

  In step S612, the video data re-encoded from the server using the identification information and the address information indicating the position of the video frame in the GOP described above are received. Note that the address information may always be returned from the server, or may be returned only when a condition is given so that the address information is returned when the server side is instructed to perform combined editing.

  In step S613, as shown in FIG. 8, the original video data and the video re-encoded by the server are combined to generate one stream. At this time, as shown above, it is confirmed whether the capacity of the re-encoded video data is the same as the capacity of the transmitted original video data. If it can be confirmed that the capacity of the original video data is the same, the composition processing is completed by updating the management information only for the data replacement and re-encoding unit.

  When the synthesizing process is completed, the process proceeds to S614 to finish the combination editing. In this flowchart, the server is inquired after the shooting mode is determined in step S610. However, the order may be changed so that the shooting mode is determined and data is received after confirming the completion of processing at the server. Good.

  As described above, even if there is a situation where you want to shoot during combined editing in the device, you can move to shooting while continuing combined editing by automatically switching combined processing to processing at the server. And convenience is improved.
