Description

  The present invention relates to a technology for downloading content data via a network.

  2. Description of the Related Art In recent years, with the spread of broadband lines to homes, a network environment that can distribute large-capacity content (information content) centered on video and music to homes without stress is being prepared. Furthermore, coupled with the development of content compression technology and distribution technology, it is now possible to distribute content to the home while maintaining high quality.

  On the other hand, at home, not only personal computers but also household appliances such as televisions and hard disk recorders, the number of devices with network connection functions is increasing, and the number of devices that acquire and use content distributed via broadband lines is also increasing. Yes. With the advancement of such content compression and distribution technologies and the increase in the number of playback devices connected to the network in the home, content is distributed to these playback devices and content usage fees (viewing fees) are received from users. A content distribution service that collects The service of Non-Patent Document 1 is an example.

  There are roughly two types of content distribution methods via the network.

  One is a streaming method in which a playback device acquires content data from a network and sequentially plays back. The data storage function is not necessary for the playback device except for the temporary storage (buffer memory, etc.) between acquisition from the network and playback, and the user can specify the content and start playback immediately. Therefore, it is a method that is easy to implement and use.

The other is a download method in which a playback device collects content data from a network, stores it in a data storage function, and plays it back after the storage is completed. The playback device needs a large-capacity data storage function for storing the entire content, such as a hard disk drive (HDD), but has the following advantages over the streaming method.
Provide high-quality content that does not depend on network quality or bandwidth.
Content reproduction quality degradation due to missing content data does not occur.
Playback operations (trick play) such as fast forward / rewind / cue up and down in the content are easy.
It is easy to copy (copy) content to other media.

  For this reason, download methods are being adopted in content distribution services that place importance on content quality. The service of Non-Patent Document 1 is an example.

  However, if importance is placed on the quality of content in the distribution service, the data size of the content becomes large even when the content compression technique is applied. In the download method, since the entire content is downloaded at a time, it takes a long time to accumulate and reproduce the content.

  In order to solve such a problem, there is a progressive download reproduction technique that can start reproduction of content after a certain amount of content has been accumulated, even if not all of the content has been downloaded. In this technique, content can be reproduced from the accumulated part, and unexecuted download execution and reproduction can be performed simultaneously. The service of Non-Patent Document 1 employs this technology.

  On the other hand, there is a digest reproduction technique that can realize a “look-ahead” of content by reproducing a plurality of reconstructed contents such as characteristic scenes based on a predetermined standard. Thus, since the user can grasp the outline of the content without reproducing the entire content, the technology is used for generating / reproducing the content sample, the trailer, and the shortened version.

  Patent Documents 1 and 2 are listed as related to the digest reproduction technology.

  Patent Document 1 discloses that, in conventional content distribution, when downloading after viewing and downloading a sample, the formal content is downloaded, which is troublesome. Furthermore, in order to solve this problem, the distribution side first downloads the formal content, distributes the profile specifying the playable area, and controls the reproduction by the profile, so that the digest can be synthesized and reproduced. It is disclosed.

  In Patent Document 2, in order to provide content and a digest without imposing a load on the network, the receiving terminal downloads a representative image of the content as a digest, and then receives the content excluding the representative image. And streaming playback is disclosed.

The world's first high-definition video download distribution service that can be dubbed to Blu-ray Discs, etc. started with “TSUTAYA TV on acTVila” (News Release) http://actvila.jp/pdf/press_20081210.pdf

  Here, let us consider progressive reproduction of the digest part in Documents 1 and 2.

  In the conventional example of Patent Document 1, since the entire digest is downloaded after the digest is downloaded, the digest can be progressively reproduced first. However, since the entire download is performed again including the digest part, the efficiency is low.

  In the invention of Patent Document 1, since the digest portion is reproduced after the entire download is completed, it takes too much time to perform the progressive reproduction of the digest portion.

  Furthermore, in the invention of Patent Document 2, since the entire digest portion is downloaded and then reproduced by streaming, the digest portion can be progressively reproduced first. However, the entire download is not considered.

  As described above, none of the documents considers the efficient download of the whole while considering the progressive reproduction of the digest portion.

  In order to solve the above-mentioned problem, in the present invention, the content is composed of a plurality of segments distributed via a network, and is subject to a digest composed of a characteristic scene for each of the plurality of segments. Information on whether or not multiple segments to be downloaded via a network can be digested in a content processing device that downloads and records content that can be divided into those that are not subject to digest. A control unit that determines the download order in segment units in preference to those that are not digest targets, and a management unit that registers the download order in segment units determined in the control unit And a registered Dow registered in the management unit. In accordance with the load order, to download in segments.

  The apparatus further includes a recording unit that records the downloaded segments in accordance with the download order registered in the management unit, and the management unit manages whether or not the recording unit records in segment units. To do.

  The apparatus further includes a playback unit that plays back the segments managed as recorded by the management unit.

  Further, in the apparatus, the management unit further manages whether the segment to be digested and all the segments are recorded by the recording unit, and the segment to be digested by the management unit is A selection unit for detecting whether it is managed as recorded or whether all the segments are managed as recorded by the management unit and presenting a reproducible digest or the entire reproducible content Is further provided.

  In another aspect of the present invention, the content is composed of a plurality of segments distributed via a network, and each of the plurality of segments is a digest target composed of a characteristic scene. A plurality of segments to be downloaded via a network in a content processing apparatus that downloads and records and plays back content that is divided into non-targeted segments and whose segments to be digested are classified into a plurality of digest groups. Information about which digest group is subject to, or not subject to digest, and in order of one that is subject to one digest group, one that is subject to another digest group, and one that is not subject to digest, SE A control unit that determines a download order in a unit of a document and a management unit that registers a download order in a segment unit determined by the control unit, and downloads in a segment unit according to the download order registered in the management unit. Do.

  The apparatus further includes a recording unit that records the downloaded segments in accordance with the download order registered in the management unit, and the management unit manages whether or not the recording unit records in segment units. To do.

  The apparatus further includes a playback unit that plays back the segments managed as recorded by the management unit.

  In the apparatus, the management unit further manages whether each of the plurality of digest groups and all the segments are recorded by the recording unit, and records each of the plurality of digest groups by the management unit. A selection unit for detecting whether or not all segments are managed as recorded by the management unit and presenting a digest group that can be played back or the entire content that can be played back Is further provided.

  According to the present invention, in consideration of progressive playback of the digest portion, the digest portion can be prioritized and can be played back at the time of recording, so that the content outline can be obtained without waiting for the entire download to be completed. Can be grasped. In addition, since the remainder other than the digest portion is downloaded after the digest portion is downloaded, the entire content can be efficiently downloaded.

  In addition, when a plurality of digests are set for one content, ranking is made among the plurality of digests, and playback can be performed at the time when the plurality of digests are downloaded and recorded.

  Example 1 according to the present invention will be described with reference to the drawings.

  In this embodiment, when one content is considered as an aggregate made up of a plurality of segments, a plurality of segments configured as digests are preferentially downloaded. Therefore, playback can be started simultaneously with completion of downloading of a plurality of segments for digest without waiting for completion of downloading of one content.

(Configuration of Example 1)
The configuration according to this embodiment will be described with reference to FIG. As shown in FIG. 1, the content distribution system according to this embodiment includes a content processing device 1 and a content distribution server device 3 connected via a communication network 2.

  The communication network 2 is a network using a wired LAN or a wireless LAN such as an optical line, a communication cable, a telephone line, etc., and can transmit and receive data according to a predetermined communication protocol between connected devices. To do.

  The content distribution server device 3 holds segment information including content data composed of a plurality of segments and information indicating whether or not to be digested. And according to the request | requirement from a user, content data and segment information are delivered via the communication network 2. FIG.

  The content processing apparatus 1 is, for example, an HDD recorder, a television having a storage function, a PC, or the like, acquires segment information from the content distribution server apparatus 3, determines the download order for each segment, and determines the determined order. The download is executed based on the segment information, and storage / reproduction is performed.

  The content processing apparatus 1 includes a communication unit 10, a download recording unit 11, a download control unit 12, a content recording unit 21, a segment information management unit 22, a reproduction unit 31, and a reproduction control unit 32.

  The communication unit 10 performs processing based on a communication protocol so that the download control unit 12 and the download recording unit 11 can communicate with the content distribution server device 3 via the communication network 2.

  When the download control unit 12 is instructed to start downloading content, the download control unit 12 acquires segment information including information indicating whether the content is a digest target from the content distribution server device 3 via the communication unit 10. Based on the information, the digest target segment is prioritized and the download order for each segment is determined, and the segment information is registered in the segment information management unit 22 together with the determined order. In addition, the download recording unit 11 is instructed to download based on the determined download order.

  The download recording unit 11 downloads content for each segment in the determined download order according to an instruction from the download control unit 12 and stores the content in the content recording unit 21. Also, content recording information is acquired from the content recording unit 21 and notified to the download control unit 12. As a content download method, for example, data transfer communication protocols such as FTP and HTTP may be applied.

  The content recording unit 21 is a mass storage device such as a hard disk, an optical disk, or a flash memory, and records the content downloaded by the download recording unit 11.

  The segment information management unit 22 holds and manages the segment information acquired and added with the download order in the download control unit 12. Further, the held segment information is notified to the reproduction control unit 32.

  The playback unit 31 plays back the content recorded by the content recording unit 21.

  The reproduction control unit 32 acquires segment information from the segment information management unit 22, and instructs the reproduction unit 31 to reproduce the digest that is preferentially downloaded and the content itself according to the information.

(Operation of Example 1)
Next, the operation of the present embodiment will be described with reference to the drawings.

  First, content segment and digest playback will be described.

  FIG. 2 shows that digests D1 are obtained by extracting characteristic segments S1 to S5 from the content C1 and reconstructing them. In order to extract a characteristic segment, for example, selection may be made based on a change point of video or audio, or may be selected in content creation work. Further, the segments constituting the digest D1 may not be arranged in time series of the original content C1, as indicated by S3 and S4. In the content C1, a segment that is blank like the segment denoted by reference numeral 201 can be regarded as a virtual segment of the content C1 that is not related to the digest.

  Next, digest playback of the content distribution service of this embodiment will be described.

  The digest playback process is started when a user selects content to be downloaded. Note that content selection is performed with reference to content information (content name, content, price, usage period / number of times, etc.) obtained from the content distribution server device 3 or other information providing server device (not shown). .

The process for performing the digest reproduction is as described above, and the main processes are as follows.
(A) Download order determination / registration process including segments related to digest by download control unit 12 (B) Download / accumulation process for each segment in the order determined by download control unit 12, download recording unit 11, and content recording unit 21 (C) Reproduction Process Based on Segment Information by Reproduction Unit Control Unit 32 and Reproduction Unit 31 These processes will be described in detail below.

  First, the download order determination / registration process (A) in the download control unit 12 will be described with reference to the flowchart of FIG.

  First, segment information regarding the content to be downloaded is acquired from the content distribution server device 3 (S1001). Here, the segment information includes at least the absolute position (position from the beginning of the content) and the size of the segment constituting the digest in the content. As an example of segment information, there is metadata specified in the standard ARIB STD-B38 “Encoding, transmission and storage control system in server type broadcasting” established by the Radio Industries Association (ARIB).

  Next, the acquired segment information is analyzed and registered in the segment information management unit 22.

  Here, an example of the segment information table registered and managed by the segment information management unit 22 will be described with reference to FIG. The segment information table holds a download order 301, a segment identifier 302, a head position 303, a size 304, a recording identifier 305, and a digest target determination 306.

  In the download order 301, the download order of segments is registered. In the segment identifier 302, an identifier for uniquely specifying a segment is registered. In the head position 303, an absolute position in the content of the segment is registered. In the size 304, the data size of the segment is registered. In the recording identifier 305, a recording identifier for uniquely specifying a segment accumulated in the content recording unit 21 is registered. Information indicating whether the segment is a digest target is registered in the digest target determination 306. Note that the end position may be used instead of the size.

  In the segment information table shown in FIG. 4, the segment indicated by reference numeral 306 has a download order of “first”, an identifier of “S1”, a head position of “0” from the top of the content, and a size of “12000”. In addition, it is registered that the recording identifier is “FILE1” and the digest target determination is “target”. Reference numerals 307 and 308 are interpreted in the same manner.

  Returning to FIG. 3, by analyzing the segment information, the identifier of the segment to be digested is acquired and registered in the table (S1002). If no segment identifier is specified, an identifier is generated and registered so as not to overlap.

  Next, by analyzing the segment information, the head position and size of the segment to be digested are acquired and registered in the table (S1003).

  Next, for the registered digest target segment, information indicating that it is a digest target is registered in the table (S1004). At the same time, the download order is registered for these digest target segments so that the order is prioritized. If the order of digest playback is specified in the segment information, the download order follows that order. If the order is not specified, it is determined and registered independently, for example, determined in the order of the start position of the segment.

  Next, it is determined whether or not the registration process for all the segments that are the digest target has been completed (S1005). If not completed, the process returns to S1002. When completed, the digest non-target portion (the blank portion of the content C1 in FIG. 2) in the content is extracted, and the segment identifier, the head position, the size, and the digest target are excluded, as in S1002-S1004. Information and download order are registered in the table (S1006). Here, the download order is registered so as to follow the order registered in the digest target. The extraction of the non-digest portion is performed based on the head position and size of the digest target segment already registered in the table.

  Next, it is determined whether or not the registration process for all segments that are not subject to digest has been completed (S1007). If not completed, the process returns to S1006. If completed, the series of processing ends.

  Next, the download / accumulation process (B) in the download control unit 12, the download recording unit 11, and the content recording unit 21 will be described with reference to the flowchart of FIG.

  First, the download control unit 12 refers to the table in FIG. 4 of the segment information management unit 22 and determines the segment having the highest download rank 301 as a download target among the segments for which no recording identifier is registered (S2001). .

  Next, the download control unit 12 acquires the head position 303 and the size 304 necessary for acquiring the content data of the segment determined to be a download target (S2002).

  Next, the download control unit 12 notifies the download recording unit 11 of the start position and size, and instructs the download of the content related to the segment. The download recording unit 11 requests content distribution to the content distribution server device 3 in accordance with the instruction (S2003).

  Next, the download recording unit 11 receives the content distributed from the content distribution server device 3, and instructs the content recording unit 21 to store the received content (S2004).

  When the storage of the content in the content recording unit 21 is completed, the download recording unit 11 acquires the stored segment recording identifier from the content recording unit 21 and notifies the download control unit 12 of it. The download control unit 12 registers the notified recording identifier in the table of FIG. 4 of the segment information management unit 22. (S2005).

  Here, it is determined whether or not the download / accumulation process has been completed for all segments registered in the table of FIG. 4 (S2006). If not completed, the process returns to S2001. If completed, the series of processing ends.

  In FIG. 5, even if the head position and size of the segment are specified in video frame units in S2002, when a distribution request is made to the content distribution server device 3 in S2003, in byte units, etc. The unit to be specified may be changed. In this case, segment information may be calculated from unit conversion information.

  Next, the reproduction process (C) by the reproduction control unit 32 and the reproduction unit 31 will be described with reference to the flowchart of FIG.

  When the user instructs reproduction, the reproduction control unit 32 refers to the table in FIG. 4 of the segment information management unit 22 and selects the segment with the highest download rank 301 among the segments with the recorded identifier registered. And the record identifier is acquired (S3001).

  Next, the playback control unit 32 notifies the playback unit 31 of the acquired recording identifier and instructs playback. The reproducing unit 31 reproduces and outputs the segment specified by the notified recording identifier from the content recording unit 21 (S3002).

  Next, the playback unit 31 determines whether playback processing has been completed for all segments (S3003). If not completed, the process returns to S3001. When completed, the series of processing ends.

  Note that the start of the reproduction process may not be completed for all segments. That is, when the determined recording identifier of the reproduction target is acquired in S3001 of FIG. 6, the segment can be reproduced even if the reproduction target accumulation process determined thereafter is not completed.

  In addition, by applying the progressive download reproduction technology, it is possible to execute the reproduction process simultaneously with the completion of the download of the reproduction target. In this case, the process of S2005 in FIG. 5 is executed immediately before S2004 so that the recording identifier is acquired before the download process.

  In this way, the download order can be determined so that the digest target segment can be preferentially downloaded, and the digest target segment downloaded preferentially can be reproduced in advance.

  Therefore, the user can reproduce the digest portion without waiting for the entire content to be downloaded.

  In addition, by downloading the digest portion and then downloading the rest, the entire content can be efficiently downloaded.

  In the present embodiment, the digest non-target portion is downloaded following the digest target portion having a high priority, but these may be distinguished from each other.

  That is, in FIG. 3, the process is performed up to S1005, the process proceeds to FIGS. 5 and 6, and only the segment related to the digest target is downloaded / stored / reproduced.

  Then, in response to an instruction for the entire content separately, the processing from S1006 onward in FIG. 3 is performed, and the processing proceeds to FIGS. 5 and 6 to download, store, and play back segments that are not subject to digest.

  In this way, it is possible to omit the download of segments not subject to digest until an instruction is given to the entire content or when no instruction is given. Accordingly, the capacity of the content recording unit can be saved, and the network bandwidth at the time of content distribution and the load on processing can be reduced.

  A second embodiment according to the present invention will be described with reference to the drawings.

  In the first embodiment, the case where one digest playback portion is set for one content is considered. However, in this embodiment, a plurality of digest playback portions are set for one content. Consider the case.

(Configuration of Example 2)
The configuration of this embodiment is the same as that of the first embodiment.

(Operation of Example 2)
Next, the operation of the present embodiment will be described with reference to the drawings.

  First, content segments and a plurality of digest playback contents will be described. FIG. 7 shows the relationship between the content C2 and the digest group that is the digest playback content. As in FIG. 2 of the first embodiment, each of the plurality of digest groups is obtained by reconstructing characteristic segments extracted from the content C2. For example, the digest group G1 in FIG. 7 is composed of characteristic segments (S1, S2, S3) extracted from the content C2. Note that the segments constituting the digest group may overlap. For example, segment S3 overlaps with group G1 and group G2, and segment S5 overlaps with group G2 and group G6.

  Next, digest playback of the content distribution service of this embodiment will be described. The present embodiment is the same as the first embodiment except that the user can execute a plurality of digest reproductions on the same content. Below, it demonstrates centering on a different part from Example 1. FIG.

  First, the download order determination / registration process (A) in the download control unit 12 will be described with reference to the flowchart of FIG.

  First, similarly to S1001 in FIG. 3, segment information is acquired (S4001).

  Next, the acquired segment information is analyzed and registered in the segment information management unit 22.

  Here, the segment information table registered and managed by the segment information management unit 22 and related to the digest group will be described with reference to FIG.

  This table holds a group identifier 601, a constituent segment identifier 602, and a recording state 603.

  In the group identifier 601, an identifier that is information for uniquely specifying a digest group is registered. In the constituent segment identifier 602, a set of identifiers of segments constituting the digest group is registered. In the recording state 603, information indicating whether the download accumulation recording of the segments constituting the digest group has been completed is registered.

  In the table shown in FIG. 9, it is registered that the digest group indicated by reference numeral 604 has a group identifier “G1”, identifiers “S1, S2, S3”, and “recorded”. Reference numerals 605 and 606 are interpreted in the same manner.

  Returning to FIG. 8, by analyzing the segment information, the identifier of the digest group is acquired and registered in the table (S4002). If the digest group identifier is not specified, the identifier is generated and registered so as not to overlap.

  Next, by analyzing the segment information, all the constituent segment identifiers of the digest group are acquired and registered in the table (S4002). Here, the constituent segment identifier 602 is registered in consideration of the segment reproduction order during digest reproduction.

  Next, registration processing is executed in the order of digest playback for the segments constituting the digest group. That is, as in S1002 to 1004 in FIG. 3, information such as identifiers for each segment is acquired and registered (S4005 to 4007).

  Note that the processing of S4005 to 4007 may be performed when it is determined whether or not the segment to be registered has already been registered in S4004.

  Next, it is determined whether or not the registration process has been completed for all the segments constituting the digest group (S4008). If not completed, the process returns to S4004. If completed, it is determined whether or not registration processing has been completed for all digest groups (S4009). If not completed, the process returns to S4002. If completed, S4010 and S4011 are performed as in S1006 and S1007 of FIG.

  Next, the download / accumulation process (B) in the download control unit 12, the download recording unit 11, and the content recording unit 21 will be described with reference to the flowchart of FIG.

  After the recording identifier is registered in S2005 of FIG. 5, the digest group is selected with reference to the table of FIG. 9, and whether all the segment identifiers included in the selected group have been recorded is shown in the table of FIG. Check by referring to the record identifier.

  If it has already been recorded, “recorded” is registered in the recording state 603 of the group selected in the table of FIG.

  Next, the reproduction process (C) by the reproduction control unit 32 and the reproduction unit 31 will be described only with respect to differences from the first embodiment, using the flowchart of FIG.

  At the beginning of FIG. 6, when the user designates reproduction of the digest group recorded in the table of FIG. 9, the processing from S3001 to S3003 is performed for all segment identifiers included in the group.

  In this way, when a plurality of digest groups are set for one content, it is possible to reproduce the content downloaded and stored for each digest group.

  In other words, a downloaded digest group among a plurality of digest groups can be played back without waiting for another digest group to be downloaded.

  A third embodiment according to the present invention will be described with reference to the drawings.

  In the present embodiment, a list is presented to the user regarding the targets and operations related to digest playback and overall content playback related to distinguishing between the digest target portion and the non-digest target portion described at the end of the first embodiment. An example is shown.

(Configuration of Example 3)
The configuration according to the present embodiment will be described with reference to FIG.

  In FIG. 10, a content selection unit 13 is newly provided with respect to FIG.

  In response to a user instruction, the content selection unit 13 acquires segment information from the segment information management unit 22, and presents a list regarding digest playback and playback of the entire content based on the segment information. Then, the operation menu is presented to the user, and when the user gives an instruction for digest reproduction or reproduction of the entire content, the reproduction control unit 32 is instructed to reproduce. When there is a download instruction for digest playback or playback of the entire content, the download control unit 12 is instructed to download. The segment information acquired by the content selection unit 13 is the table shown in FIGS. 4 and 9, and it is confirmed whether or not the segments or groups in these tables have been recorded. Present.

(Operation of Example 3)
Next, the operation of the present embodiment will be described with reference to the drawings.

  FIG. 11 is an example of a screen showing a list related to digest playback and overall content playback that the content selection unit 13 presents to the user.

  A screen 700 showing a digest reproduction list includes digests 701 to 704 and a menu 705 for each content (A, B, C). Each of the digests 701 to 704 indicates information on whether or not the entire content can be reproduced together with information on the content such as a title name. In FIG. 11, “reproduction of entire content” is displayed, reproduction is possible, and when “downloading of entire content” is displayed, it is necessary to download in order to make the entire content reproducible. It shows that. Digests 702 and 703 are displayed when there are a plurality of digests (G1, G2) in the same content B.

  A screen 800 showing a reproduction list includes contents (A, C, D, E) 801 to 804 and a menu 805. Each of the contents 801 to 804 indicates information indicating whether digest playback is possible, as well as information on the contents such as the title name. In FIG. 11, the contents A and C can be digest reproduced.

  In FIG. 11, the user can make a selection by moving black frames such as the digest 702 and the content 802. Menus 705 and 805 present menus of operations performed by the user. Accordingly, for the item selected with the black frame, the operation presented in the menu can be performed.

  In the menu 705, digest playback of the content selected with the blue button can be performed with the 706, download of the entire content selected with the green button can be started with the 707, and a playback list of the entire content can be started with the yellow button with the 708. It shows that the screen can be changed to. Note that 707 is changed to operation details corresponding to the selected content.
