JP4803501B2 - Content sending device - Google Patents

Description

  The present invention relates to a content transmission device that stores moving image content and provides the stored moving image content to a playback device.

  In recent years, many apparatuses for accumulating and reproducing moving image contents have been announced. In many cases, moving image data is recorded with one program or a unit divided by CMs in the program as one title. In the case of content shot with a video camera, the unit from when the shooting button is pressed until shooting stops is recorded as one scene. When reproducing these recorded contents, only one title or one scene is rarely reproduced, and a plurality of titles or scenes are often combined (connected) and reproduced as new contents. A combination of multiple titles and scenes is called a playlist. Various methods have been proposed for creating a playlist. Basically, a playlist is created by sequentially specifying titles.

  A method of creating a playlist while checking thumbnails on the screen is disclosed in Patent Document 1 below. The device disclosed in Patent Document 1 is a recording / reproducing device, and a video signal is output from the recording / reproducing device to reproduce content. The recording / reproducing apparatus has a main body switch or a remote controller, and can control the recording / reproducing apparatus. Naturally, the recording / playback apparatus can display a menu for selecting contents and thumbnails, and similarly can display a menu for creating a playlist and give instructions for creating a playlist using a remote controller.

  By the way, with the recent spread of home networks, a viewing form via a network is often used instead of viewing of moving image content by a recording / reproducing apparatus disclosed in Patent Document 1. FIG. 6 shows an example of a viewing mode via a home network (network). As shown in FIG. 6, the playback device 601 and the moving image sending device 602 are connected via a network 605. The moving image sending device 602 has a moving image content storage unit 603 that stores moving image content. The playback device 601 can acquire a list of moving image contents included in the moving image transmission device 602 by an operation of the remote controller 604 by a user (not shown), and can display the list on a display unit (not shown). At this time, the list can be displayed hierarchically.

  Also, the playback device 601 can acquire one content selected from the acquired list from the video transmission device 602 and display the content (video content). A series of commands exchanged between the playback device 601 and the moving image transmission device 602 is performed in accordance with a standard specification. Accordingly, the same operation is possible even if the manufacturer is different as long as the playback device and the sending device comply with the standard. For example, even if there are playback devices in each room such as a living room on the first floor and a bedroom on the second floor, the content can be played back on each playback device as long as each playback device is connected to the network. . An example of such a standard is a standard established by DLNA (Digital Living Network Alliance).

  Here, an example of a conventional viewing mode via the home network will be described more specifically with reference to FIG. As shown in FIG. 7, a moving image sending device 702 (corresponding to a content sending device described later) and a playback device 701 are connected via a network 705. The memory device 707 and the PC 706 are devices for storing moving image content in the moving image content storage unit 703 of the moving image transmission device 702. First, the moving image content is entered into the moving image content storage unit 703 of the moving image transmission device 702. There are various methods for putting moving image content, but some examples will be shown.

  The first example is a method of transferring data held by the PC 706 connected on the network 705. The PC 706 recognizes the video transmission device 702 as a network disk or FTP server, and transfers the file to a desired directory. The next example is a method of transferring data in the memory device 707 via the USB terminal of the moving image sending device 702. There are a method of using the PC 706 and a method of automatic transfer. When using the PC 706, the memory device 707 is recognized as an external disk of the moving image sending device 702, so that the user can copy the moving image content on the memory device 707 to a desired directory of the moving image sending device 702.

  In the case of automatic transfer, the moving image content in the memory device 707 connected to the USB terminal is automatically copied to the moving image transmission device 702. Once the moving image content is stored in the moving image content storage unit 703 of the moving image transmission device 702, the memory device 707 and the PC 706 may be disconnected from the network 705. Thereafter, data is exchanged between the playback device 701 and the moving image transmission device 702.

  The playback device 701 can select and play a playback instruction for the moving image content stored in the moving image content storage unit 703 of the moving image transmission device 702. An example is shown in FIG. FIG. 8A shows an initial screen of the playback device 701. A moving image sending device on the network is automatically detected, and a list thereof is displayed. In this example, since one moving picture sending device 702 is detected, only “server 1” which is the name of the moving picture sending device 702 is displayed. The user selects and determines the displayed “server 1” portion (icon). The selection method includes a method of pressing a cursor button on the remote control, but the method is not particularly limited. Similarly, the determination method includes a method of pressing a determination button on the remote controller, but the method is not particularly limited.

  When one moving picture transmission device is selected, the screen transitions to FIG. 8B showing the next screen. On this screen, the directory information of the moving picture transmission device 702 is displayed. In this example, two directories (icons) “moving image” and “user” are displayed. Note that the moving image sending device 702 uniquely determines how to divide the directory. Here, when “moving image” is selected and determined, a transition is made to FIG. 8C showing the next screen. In this example, “travel” and “athletic meet” are displayed. Further, when “travel” is selected and determined, a list of contents as shown in the screen of FIG. 8D is displayed. In this example, “Hokkaido”, “America”, and “Alaska” are displayed. If the user wants to return to a higher level, means are provided for returning by pressing a “return” button or the like on the remote control.

  Here, when “Hokkaido” is selected and determined in the state of FIG. 8D, an actual moving image is reproduced (FIG. 9A). By operating a remote control or an icon on the screen, playback can be paused or ended. Note that the display of directories and contents may be in the form of a list as shown in FIG. 9C instead of the display shown in FIG. If the number of directories and contents is too large to fit on one screen, a desired directory and contents can be selected by performing a page turning operation (scrolling). In the above example, the content and the directory are not mixed, but the directory and the content may be mixed. For example, in FIG. 9B, a directory “Dance” may be displayed together with two contents “Relay” and “Tare”.

  Next, operations of these playback devices and moving image sending devices will be described with reference to examples of their protocols. Hereinafter, directories and contents are collectively referred to as objects. FIG. 10 shows object management information. The object management information includes “ID” 1001, “type” 1002, “name” 1003, “resource” 1004, and “other information” 1005. “ID” 1001 is an arbitrary ID for identifying the object. Each object included in one moving image transmission apparatus has a unique ID. “Type” 1002 is a value for distinguishing between a directory and a content. “Name” 1003 represents the name of the object. “Resource” 1004 is described when the object is content, and describes the location where the content exists and the format of the content. The location where the content exists is described in a URL format, for example. “Other information” 1005 includes the creation time of the object. Object management information is assigned to each object.

  The commands requested by the playback device 701 to the moving image sending device 702 are a BROWSE command for acquiring object management information and a GET command for acquiring content. When a directory is selected and the enter button is pressed, a BROWSE command is sent from the playback device 701 to the moving image sending device 702 together with the ID of the selected directory. In response to the BROWSE command, the moving image sending apparatus 702 returns the number of objects included in the corresponding directory and the respective object management information. Based on the returned information, the playback device 701 displays the lower-level directory and contents.

  When the content is selected and the enter button is pressed, the playback device 701 issues a GET command together with the resource (content URL) that the content has. This is the same as the normal HTTP protocol, and the moving picture sending device 702 sends the header and the content entity to the playback device 701 as a response to the command. These examples are shown in FIG. Although the basic concept has been described in FIG. 11, the start position and number of IDs to be acquired may be specified in the BROWSE command so that a case where the number of objects included in one directory is actually large can be dealt with. it can.

  Here, FIG. 12 shows an example of the configuration of a conventional moving image transmission apparatus. When capturing content (moving image data), the moving image data capturing unit 1209 captures the content via the network interface 1202 and stores the content in the moving image data storage unit 1208. When the content is captured and the moving image data storage unit 1208 is changed, the object information configuration unit 1207 refers to the moving image data storage unit 1208 and updates the object information DB 1206. When the playback apparatus 701 acquires object management information when displaying directory information, the command processing unit 1203 processes command data received from the network interface 1202. If the command processing unit 1203 is a BROWSE command, the command processing unit 1203 accesses the object information DB 1206 via the object information access unit 1204, creates a response to the BROWSE command, and notifies the playback apparatus 701 of the result via the network interface 1202. .

When the playback device 701 plays back content, the command processing unit 1203 processes command data received from the network interface 1202. If the command processing unit 1203 is a GET command, the command processing unit 1203 accesses the moving image data storage unit 1208 via the moving image data access unit 1205 and sends the content entity to the playback device 701 via the network interface 1202. Since the URL of the content may not directly represent the file name, the moving image data access unit 1205 refers to the object information DB 1206 in order to obtain the file name of the moving image data.
Japanese Patent No. 3612274

  Since the recording / reproducing apparatus disclosed in Patent Document 1 has a video output, it has a user interface for creating a playlist and can output it to a monitor. However, since the video transmission device connected to the conventional home network as described above does not have a video output, content can be transmitted in response to a request from the playback device, but a plurality of content can be connected and edited. The user cannot create a playlist that is the content that has been created. Although it is possible to create a playlist with a protocol agreed between the playback device and the sending device, this requires a function that allows the playback device to interpret a special protocol, and the devices that can be operated are limited.

The second icon here corresponds to an additional icon described later.

  The content transmission device of the present invention has the above-described configuration, and it is not necessary to cause the playback device on the home network to interpret a special protocol, and a playlist is generated in the content transmission device using the playback device. The playlist can be viewed on the playback device.

<First Embodiment>
The first embodiment of the present invention will be described below. A method of creating a playlist using a playback device will be described with reference to FIGS. FIG. 1B shows a screen state after “Server 1” shown in FIG. 1A is selected. Note that the screens shown in FIGS. 1 to 3 and 5 are screens displayed on the display means of the playback apparatus. Compared with FIG. 8B, directories of “edit” and “playlist” (also referred to as icons) are added. When “edit” is selected by the user, a transition is made to the screen shown in FIG. In this example, there are two directories, “new” and “delete playlist”.

  Here, when “new” is selected by the user, a transition is made to the screen shown in FIG. In the initial state, there are three directories of “complete”, “cancel”, and “delete”. Since the current state is a playlist editing state, the user reproduces a moving image (also referred to as content) in order to designate a moving image to be registered in the playlist. For example, returning from this state (the state shown in FIG. 1 (d)) to the second hierarchy, when “Movie” is selected by the user, the screen changes to the screen shown in FIG. 2 (d). In this state, when “Athletic meet” is selected by the user, the screen transitions to the screen shown in FIG. 3A, and when “Relay” is selected by the user, the moving image “Relay” is reproduced.

  When the video is played (the screen shown in FIG. 3C) and played for a while (temporary playback), the user stops the video, selects the next video and plays it in the same way, and registers it in the playlist. Add (combine) videos. In other words, the playlist generation unit 412 described later generates a playlist based on the reproduction of the moving image by the user. After adding the moving image in this way, when “edit” is selected from the top screen (the screen shown in FIG. 1B) and “new” is selected from the screen shown in FIG. 1C, FIG. As shown in (a), in addition to “complete”, “cancel”, and “delete” in the initial state, the added moving images (“relay”, “dance 1”, “dance 2”) are displayed.

  When the user wants to delete the added video, when the user selects “Delete” shown in FIG. 2A, the screen transitions to the screen shown in FIG. 2B, and the user can delete it by playing the video. it can. When all the additions of the moving images have been completed, the user selects “Done” shown in FIG. 2A, so that the screen transitions to the screen shown in FIG. That is, the playlist generation unit 412 to be described later stores the generated playlist as a regular playlist in the object information DB 406 to be described later when “complete” shown in FIG. 2A is selected.

  Then, when the user selects a directory called “playlist” on the top screen (the screen shown in FIG. 1B), the corresponding playlist is transmitted from the content transmission device 401 described later, and based on that, FIG. As shown in (b), playlists (“list 1”, “list 2”) are displayed, and selection and reproduction by the user are possible. That is, a playlist is registered using a directory operation and a playback operation. In this example, the playlist is one level, but a playlist having a plurality of levels can be formed by extending the directory designation method.

  Here, FIG. 4 shows a block diagram of the content transmission apparatus 401 according to the first embodiment. The pseudo object information management unit 411 (corresponding to the control means described above) performs processing to return object information in response to the BROWSE command, but returns object management information (directory information) as described with reference to FIG. In some cases, pseudo object information generated by the pseudo object information management unit 411 is returned to create a playlist. Here, the pseudo object information refers to a virtual directory (icon) for creating a playlist. Specifically, the information is information such as the directory “edit” shown in FIG. 1B and the directory “new” shown in FIG.

  When the pseudo object information management unit 411 determines that the command is a BROWSE command for acquiring the pseudo object information, the pseudo object information management unit 411 sends information to that effect to the playlist generation unit 412 (corresponding to the playlist generation means described above) and at the same time, the playback device The corresponding pseudo object information is returned via the network interface 402 based on the instruction from the network interface 402. Note that information (not shown) (information such as a flag) that can be used to determine that the pseudo object information management unit 411 is a BROWSE command for acquiring pseudo object information is included in the command.

  The playlist generation unit 412 also acquires information on the corresponding moving image based on the temporary playback of the moving image by the playback device, and generates a playlist. When the playlist is generated, the playlist generation 412 sends the information to the object information DB 406, and the actual object information (playlist) is managed by the object information DB 406. Thereafter, when a playlist is selected by the playback device, each moving image data corresponding to the selected playlist is transmitted to the playback device via the network interface 402.

  Next, a method for transmitting a moving image specified by a playlist by the content transmission apparatus according to the first embodiment will be described. The playlist is for continuously playing back moving images, but it must be accessible to the playback device as if it were one moving image. A time code is assigned to each moving image at an appropriate interval. However, if a moving image is simply connected and transmitted to the playback device, the time code becomes discontinuous at the original file break. In order to avoid this, the virtual moving image data management unit 410 performs a time code replacement process on the moving image entity. Note that the virtual moving image data management unit 410 may generate time information corresponding to the time code without performing the time code replacement process, and send the generated time information to the playback device together with the moving image. The playback device plays back the moving image using the received time information.

<Second Embodiment>
In the first embodiment, when a playlist is generated or a movie in the playlist is deleted, an instruction to actually play a movie is issued from the playback device. Even when the playback device displays thumbnails or when the content list is displayed, the selected content is displayed as a moving image on a small screen. A video playback command may be issued.

  Therefore, in the second embodiment, the playlist designation method shown in FIG. 1 is changed, and all instructions are given only by accessing the directory. FIG. 5 shows a screen when “athletic meet” is selected in FIG. Along with each content, a directory (add icon) is displayed for each content of “add relay” and “add tweak”. For example, when “add relay” is selected by the user, the content of “relay” is played. Added to the list. The pseudo object information management unit 411 generates pseudo object information (addition icons) such as “add relay” and “add tame” and returns the generated pseudo object information to the playback device.

  The content transmission device according to the present invention does not require a playback device on the home network to interpret a special protocol, generates a playlist in the content transmission device using the playback device, and plays the generated playlist. Therefore, it is useful for a content transmission device that stores moving image content and provides the stored moving image content to a playback device.
