Description

  The present invention is a content transfer system suitable for application to a system for transferring video content data such as video data between devices connected by a cable or a network, a transmission method applied to the system, and the system The present invention relates to a display device and a recording / playback device used in the above.

  In recent years, video devices such as television receivers that can be connected to various existing networks are becoming widespread. That is, even in a general home, a personal computer device and its peripheral devices may be connected by wire or wireless to form a network (home LAN: so-called home network). Furthermore, there is a case where a network capable of transferring data with an external device via the Internet is configured. A device for performing such network connection is assumed to have a configuration in which a network connection terminal for Ethernet (registered trademark) connection is provided and connected to the network by a wire, or a configuration in which a communication processing unit for accessing a wireless LAN is provided. . Video devices such as television receivers are connected to such networks by wire or wirelessly. For example, when a television receiver is connected to a network, display can be performed by allowing the television receiver to input video data sent from another device such as a recording / playback device in the network or a server on the network. It becomes possible to make it.

  On the other hand, in recent years, an interface standard called HDMI (High-Definition Multimedia Interface) standard has been developed as an interface standard for transmitting uncompressed digital video data and the like between a plurality of video devices. The HDMI standard is a standard for individually transmitting video data as primary color data of each color in units of pixels (hereinafter, pixels are referred to as pixels). Audio data (audio data) is also transmitted using a video data transmission line during the blanking period of the video data. As primary color data to be transmitted, three primary color data (R data, G data, and B data) of additive color mixture of red, green, and blue are transmitted.

  One pixel data of each color is basically transmitted in units of 8 bits. Synchronization signals such as a horizontal synchronization signal and a vertical synchronization signal are also transmitted at the timing at which each synchronization signal is arranged. Also, a pixel clock transmission line for video data and a control data transmission line are provided. As described above, since the transmission configuration is such that non-compressed digital video data is transmitted in units of pixels, it is possible to transmit high definition video while protecting the copyright.

  When a video device such as a television receiver has both a connection with a cable such as an HDMI standard and a network connection function, display or the like can be processed for video data input through either connection. For devices on the video output side, such as a hard disk recorder, when both cable connection and network connection functions are provided, video data can be output to any connection.

  For example, a hard disk recorder and a television receiver are directly connected by an HDMI standard cable, and a network connection terminal is provided on both the hard disk recorder and the television receiver to connect to a home network. And At this time, there are two types of routes for transmitting the video content reproduced by the hard disk recorder to the television receiver: a route via an HDMI standard cable and a route via a network.

  When a television receiver receives video content from a recording / playback device such as a hard disk recorder, it acquires a content list that is a list of content that can be received through each route, and displays the content list. A process for causing the user to select and request transmission of the selected content is required.

  When there are a plurality of recording / playback apparatuses, it is possible to display the contents list of each recording / playback apparatus in an integrated manner on one display device. An example of the content list in this case is shown in FIG. It is. FIG. 12A shows a content list in which a plurality of contents recorded by the recording / reproducing apparatus 300a are arranged in time series, and FIG. 12B shows a recording / reproducing apparatus 300b created in the same manner. It is a content list. In FIG. 12C, the content lists of both recording / playback apparatuses are integrated and displayed on the display device 100. From the top of the list, “Drama 1st 2006/2/7” of the recording / playback apparatus 300a is displayed. As shown in “News 2006/2/10” of the recording / reproducing apparatus 300b, content information of both recording / reproducing apparatuses is displayed as a list in time series. By creating such a list, the user can browse the desired content simply by selecting the content to be browsed on the integrated content list, and the location where the recording / playback apparatus is actually installed No need to be aware of

Patent Document 1 describes details of the HDMI standard.
WO2002 / 078336

  By the way, in recent years, content recorded by a recording / playback apparatus is stored in an external storage medium such as a memory card, and the external storage medium is attached to a portable player having a video playback function so that the recorded video content can be stored on the go. You can also watch it on the site. In this case, even if the recorded video content is distributed and recorded on a plurality of recording / playback apparatuses, if the integrated content list as shown in FIG. 12C is used, the video to be recorded on the external storage medium Content can be easily selected.

  However, even if information on which recording / reproducing device each content was recorded on is provided with the name of the content on the content list, the recording / reproducing device is identified by the name or number assigned to the recording / reproducing device. There is a problem that the name and number are not displayed on the recording / reproducing apparatus, and various names are likely to be assigned, which is difficult. In addition, if an external storage medium has been installed in the recording / playback device in advance, even if the recording / playback device in which the external storage medium is installed is displayed on the content list, recording / playback is performed using the name and number as described above. Since the device cannot be easily specified, there is a problem that it is not easy to collect the device for using the external storage medium. Even if the recording / playback device can be specified, when the recording / playback device is located in another room, the external storage medium that stores the video content or when the external storage medium is attached to the recording / playback device. When the storage medium was removed, it was troublesome to move to a place where the recording / playback apparatus was located.

  In recent years, a display device provided with a slot for an external storage medium has come out, and it is only necessary to use the slot to solve the above-described problems. However, the display device is originally a tuner or a communication IF. Since this is a device that outputs broadcast-based video content input from the display from a display or speaker, the signal band that can be internally processed is only the band that matches the broadcast signal band, such as 30 Mbps. Processing cannot be performed for signals in the band.

  Furthermore, when the display device and the recording / playback device are connected by a transmission line (HDMI cable) of the HDMI standard, HDMI is a standard for transmitting uncompressed data, so it cannot transmit compressed data. There has also been a problem that video content cannot be stored in an external storage medium such as a memory card.

  The present invention has been made in view of such a point, and in an environment where a plurality of recording / playback apparatuses are connected to a display device via a network, an HDMI cable, or the like, content stored in the recording / playback apparatus is stored in an external storage medium. The purpose is to improve user convenience.

  The present invention stores the format information set via the display device on the recording / playback device side when the content stored in the video device of the recording / playback device is stored in an external storage medium, and stores the video content data in the format information When a specific video content is selected from the content list, the content list of the video content stored in the recording / playback device is displayed on the display device side. , Request the recording / playback apparatus to transfer video content data in a predetermined format, and the recording / playback apparatus will store the video in the format specified by the video content data transfer request from the stored video content data. The content data is extracted and transferred to the display device, and the display device receives it from the recording / playback device. Was video content data is obtained so as to be stored in the external storage medium.

  In this way, when a specific content is designated in the content list displayed on the display device, the video content data is transferred from the recording / playback device storing the designated video content data to the display device. Transferred.

  In addition, video content in a format corresponding to the format of the portable device is stored in advance in the recording / playback apparatus.

  Further, when a video content data transfer request is received from the display device, video content data in a desired format stored in advance on the recording / playback device is transferred to an external storage medium inserted in the display device. Become.

  According to the present invention, since the video content in a format corresponding to the format of the portable device is stored in the recording / playback apparatus in advance, it is not necessary to perform format conversion when transferring the video content data to the portable device.

  In this case, in response to a video content data transfer request from the display device, video content data in a desired format stored in advance on the recording / playback device is transferred to the external storage medium inserted in the display device. Even when it is difficult to specify the recording / playback apparatus storing the content data, there is no need to specify the video content data on the recording / playback apparatus by controlling the display device even when the recording / playback apparatus is at a remote location. Can be transferred to an external storage medium on the display device.

  Furthermore, it becomes possible to transfer video content data stored in an external device such as a recording / playback device to an external storage medium via a display device operated by the user, which enables intuitive operation. , User convenience is improved.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

  In this example, a video program viewing system is configured by a display device and a plurality of recording / playback devices capable of transmitting video data to the display device. FIG. 1 shows an example of the system configuration. In the room A, a display device 10a configured as a television receiver and recording / reproducing devices 30a and 30b are arranged. The display device 10a and the recording / reproducing device 30a are connected by an HDMI cable 1a, and the recording / reproducing device 30b is connected by an HDMI cable 1b. Further, the display device 10a has a function of connecting to a network by Ethernet (registered trademark) or the like, and is connected to a home LAN (Local Area Network) 2, and the room B is recorded via the home LAN 2. Data can be transmitted / received to / from the playback device 30c and the recording / playback device 30d in the room C. The display device 10b and the display device 10c have the same configuration. The recording / reproducing devices 30a to 30c are video devices capable of recording and reproducing a video program (content) using, for example, a hard disk as a recording medium.

  In the case of the system configuration shown in FIG. 1, since the display device 10a and the recording / playback device 30a and the display device 10a and the recording / playback device 30b are connected by an HDMI cable, the video recorded by the recording / playback device 30a or 30b. The data is transmitted to the display device 10a without being compressed. In this example, even video data and audio data compressed by the MPEG2 system or the like can be transmitted via an HDMI cable. Details of the compressed data transmission method via the HDMI cable will be described later.

  The display device 10a and the recording / reproducing devices 30c and 30d are connected via the home LAN 2, and video data and audio data compressed by, for example, the MPEG2 system are transmitted on the home LAN 2. For transmission via this network, for example, transmission conforming to the Digital Living Network Alliance (DLNA) standard is performed, and control data is also transmitted bidirectionally.

  Each display device 10 is provided with a memory card slot as an external storage medium insertion portion. In the configuration example of FIG. 1, a memory card slot 20a is provided in the display device 10a, a memory card slot 20b is provided in the display device 10b, and a memory card slot 20c is provided in the display device 10c. An external storage medium such as a memory card is inserted into the memory card slot 20, and the inserted memory card can store video content recorded by each recording / playback device 30. Data transfer from each recording / playback apparatus 30 to the display apparatus 10 is performed via an HDMI cable or the home LAN 2. Details of the video content data transfer processing from each recording / playback apparatus to the display apparatus 10 will be described later. Also, video content data transfer and storage operations are performed via the remote controller 60.

  FIG. 2 is a diagram illustrating a configuration example of the display device 10 of the present example. A display device 10 configured as a television receiver includes an antenna 11, and the antenna 11 is connected to a tuner 12. The tuner 12 can receive a broadcast signal, and the reception channel is selected by the tuner 12 under the control of the control unit 21. The demodulator 13 demodulates the broadcast signal received by the tuner 12 and sends the demodulated data to the decoder 14. The decoding unit 14 decodes video data compressed by a method such as MPEG2-Video or audio data compressed by a method such as MPEG2-AAC (Advanced Audio Coding), and displays the video data on the display unit 15. If it is audio data, it is output from the speaker 16.

  The decoding unit 14 also decodes the compressed signal received from the recording / playback apparatus 30 via the communication unit 17 or the HDMI IF unit 19. The decrypted data can be stored in a memory card inserted in the memory card slot 20. When a signal is received from the HDMI IF unit, the compressed signal superimposed in the blanking period in the received signal is separated by the separation unit 18 and compressed video content data (hereinafter referred to as compressed content data) is obtained. It can be taken out. Details of the process of superimposing the compressed content data on the blanking period will be described later. The control unit 21 is configured to be able to transfer data to and from the memory 22 via the control bus line, and data necessary for control is stored in the memory 22. Content list information received from a recording / reproducing apparatus 30 described later is also stored in the memory 22. The remote control signal receiving unit 23 receives a signal from the remote controller 60 (FIG. 1), and instructs each unit to perform various operations based on the control of the control unit 21.

  2, the transmission path from the communication unit 17 to the memory card slot 20 and the remote control signal receiving unit 23, and the memory card slot 20 and remote control signal reception from the separating unit 18, as indicated by bold arrows. A high-speed output bus is used for the transmission path to the unit 23. For this reason, even when the video content data is, for example, a one-hour broadcast program, transfer to the external storage medium can be performed in a shorter time.

  In addition, the display device of this example is configured to accept input including video content data encoded in a format that cannot be displayed on the display unit 15 and output it to an external storage medium. Therefore, for the purpose of making it possible to deal with various unknown formats, processing relating to the format is not performed inside the display device.

  FIG. 3 is a diagram showing a configuration example of the recording / reproducing apparatus 30 of the present example. The recording / playback apparatus 30 of this example is configured as a video recorder that receives and records a video program (content) and plays back the recorded video content. The recording / reproducing apparatus 30 includes an antenna 31 and receives a broadcast signal of a broadcast station selected by the tuner 32 based on the control of the control unit 42. The demodulator 33 demodulates the broadcast signal received by the tuner 32, and the compressed content data demodulated by the demodulator 33 is stored in the storage unit 34. Similarly, the content list including the recording date and index of each video content is also stored in the storage unit 34, but may be stored in the memory 43 described later. The format storage unit 41 stores format information of a portable device to which compressed content data is transferred via a memory card, such as PSP (PlayStation Portable (registered trademark)). Details of the format information will be described later.

  The decrypting unit 35 decrypts the compressed content data stored in the storage unit 34. The size / frame number conversion unit 36 and the encoding unit 37 perform transcoding (re-encoding) processing of the compressed content data based on the format information stored in the format storage unit 41. The size / frame number conversion unit 36 converts the screen size and frame rate of the data decoded by the decoding unit 35 in correspondence with the format information, and the encoding unit 37 specifies the converted data in the format information. To the encoded format. The re-encoded data is stored again in the storage unit 34 based on the control of the control unit 43. The storage unit 34 here functions as a format-converted content storage unit. The decoding unit 35, the size / frame number conversion unit 36, and the encoding unit 37 that perform transcoding processing of the compressed content data are collectively referred to as a format conversion unit 50.

  The superimposing unit 38 superimposes the compressed content data stored in the storage unit 34 on the data island period of the blanking period, and the superimposed compressed data is transmitted to the display device 10 via the HDMI IF unit 39. . Here, the data island period will be described with reference to FIG. FIG. 4 is a diagram showing a line configuration and a pixel configuration of one frame transmitted by the transmission configuration of this example. When the transmitted video data (main video data) is uncompressed data, a vertical blanking period and a horizontal blanking period are added. Specifically, in the example of FIG. 4, the display video area (area shown as the active video area) is pixel data of 480 lines × 720 pixels, and the number of lines and the number of pixels including the blanking period is 525. There are as lines and 858 pixels. An area indicated by double hatching during the blanking period is called a data island and is a period during which auxiliary data can be added. The superimposing unit 38 superimposes the compressed content data in this period, and the content list, text information, and the like are also transmitted using the section of the data island.

  Returning to FIG. 3, the description of the configuration example of the recording / playback device 30 will be continued. The communication unit 40 controls the data transmission with other devices such as the display device 10 via the network. is there. When the compressed data is transferred to the display device 10 via the communication unit 40, the communication unit 40 packetizes and transfers the compressed data.

  The control unit 42 is configured to be able to transfer data to and from the memory 43 via the control bus line, and data necessary for performing control is stored in the memory 43. The remote control signal receiving unit 44 receives a signal from the remote controller 60 and instructs each unit to instruct various operations based on the control of the control unit 42.

  As indicated by bold arrows in FIG. 3, a high-speed output bus is used for the transmission path from the storage unit 34 to the superimposing unit 38 and the communication unit 40. For this reason, the video content data is transferred to the display device 10 at high speed via the HDMI IF unit 39 or the communication unit 40, and even when the video content data is a one-hour broadcast program, for example, in a shorter time. Transfer can be performed.

  Next, a device used and format information setting processing example in the display device 10 of this example will be described with reference to the flowchart of FIG. The device used here refers to a portable device such as a portable game device, a portable video display device, and a mobile phone terminal that can browse video content on the recording / playback apparatus via a recording medium. The format information is information such as a compatible codec method, screen size, and frame rate in the portable device. The codec system is, for example, MPEG-2 or MPEG-4 AVC (Advanced Video Coding) if it is a video coding system, or MPEG-1 Layer 2 or MPEG-2 AAC (Audio Code system). Advanced Audio Coding). The image size is information such as resolution and aspect ratio, and the frame rate is frame rate information such as 15 fps (frame per second) and 30 fps, and information such as a scanning method. For major portable devices that are expected to be frequently used by users, device information and format information thereof are registered in advance in the display device 10 at the time of factory shipment or the like.

  In step S500, when an instruction for setting used device information is received from the user via the remote controller 60, the used device information is displayed in a list on the display unit 15 of the display device 10 (step S501). Next, it is determined whether or not the user has selected a device to be used from the existing setting device list (step S502). If the device has not been selected from the existing setting device list, the user newly uses the device. The input of information and format information is accepted (step S503). When the used device information and the format information are received by selection from the existing list or new input, the selected used device is registered as a “use candidate device” (step S504), and the received used device information and format information are stored. Then, it is transmitted to each recording / playback apparatus (step S505).

  FIG. 6 is a flowchart illustrating an example of processing after the recording / reproducing apparatus 30 receives the used device information and the format information transmitted from the display apparatus 10. First, when used device information and format information are received from the display device 10 (step S600), it is determined whether the received used device information is newly registered (step S601). When it is determined that the received used device information is newly registered, the received used device information and its format information are stored in the format storage unit 41 (step S602). If it is determined that the received used device information is already registered, it is determined whether the used device is registered as a use candidate device (step 603). If it is determined that the device is not registered as a use candidate device, the device is registered as a use candidate device (step S604). If it is determined that the used device is registered as a use candidate device, the used device is registered as “a device with high use frequency” (step S605).

  As used herein, “a device that is frequently used” refers to a device that is often used by a user as a portable device that transfers content data stored on the recording / reproducing apparatus 30. This is a setting for preferentially performing format conversion processing, which will be described later, from the format of a frequently used device, and the registration is performed by a method such as adding a flag. Here, the registration as a use candidate device or a use device with a high frequency of use is automatically performed, but the user may be required to determine whether registration is necessary or not.

  Next, an example of format conversion processing by the format conversion unit 41 of the recording / playback apparatus 30 will be described with reference to the flowchart of FIG. The reference numerals in the flowchart are the same as those in FIG. 2 for the display device 10 and in FIG. 3 for the recording / reproducing apparatus 30. In this example, the format conversion of the received content is performed based on the format information stored in the format storage unit 41 at the timing when the recording / playback apparatus 30 starts recording the content. In step S700, it is determined whether recording has started. If it is determined that the recording has started, the broadcast program being received via the tuner 32 is subjected to format conversion processing by the format conversion unit 50 (step S701). The format conversion process in this case is performed based on the format information of the device registered as “a device with high use frequency” among the used device information stored in the format storage unit 41. Even when recording is not being performed, if a format conversion instruction is received from the user (step S702), the format is converted to the designated format (step S703). The content converted into the predetermined format is stored in the storage unit 34 (step S704).

  In this example, the format conversion process has been described as an example of recording, but the content stored in the storage unit 34 is automatically converted to the format of the device registered as “frequently used device” at a predetermined time or the like. You may make it convert with.

  Next, an example of processing for receiving and displaying a content list transmitted from another device on the display device 10 of this example will be described with reference to the flowchart of FIG. First, when a content list display request is received from the user via the remote controller 60 (step S800), the content list is sent to all recording / playback apparatuses connected via an HDMI cable or a network based on the control of the control unit 21. A transmission request is transmitted (step S801). Next, it is determined whether or not the content list has been acquired from all the recording / playback apparatuses (step S802), and the reception of the content list is continued until the content lists from all the recording / playback apparatuses are completed. If it is determined that the content list has been acquired from all the recording / playback apparatuses, the received content list is displayed on the display unit 15 (step S803). In step S804, adjustment of the display order of the content list is received from the user, and the integrated content list is completed. Here, the display order of the content list is adjusted by the user's operation. However, the content list sorting method, such as date order or title alphabetical order, is set in advance, and automatic based on that setting. In other words, the display order may be adjusted.

  Next, a flowchart of FIG. 9 shows a processing example from when a specific content is specified on the display device 10 of this example until the content of the recording / playback device 30 is stored in the memory card inserted into the display device 10. Will be described with reference to FIG. First, when a selection of content is received from the user (step S900), “use candidate device” is subsequently displayed on the display unit 15, and a selection of a specific device is received from the user (step S901). The selected content information and used device information are transmitted to the recording / reproducing apparatus 30. At the same time, a request for transferring content information such as the data size of the content is also transmitted to the recording / reproducing apparatus 30 (step S902). When the recording / reproducing apparatus 30 receives the data from the display apparatus 10, the format information of the device used in the data is read from the format storage unit 41 (step S903), and the requested content is designated in the designated format. Information such as the size of the content data when converted to is transmitted to the display device 10 (step S904).

  At this time, it is also determined at the same time whether content data converted into the format specified by the display device 10 exists in the storage unit 34. That is, it is determined whether or not it is necessary to convert the format of the content data (step S905). If it is determined that format conversion is necessary, the format conversion unit 50 performs content format conversion processing (step S906).

  Next, when the display device 10 receives the content information transmitted from the recording / playback device 30, it determines whether the free space of the memory card inserted into the memory card slot 20 is sufficient to store the received content. (Step S907). If it is determined that there is not enough free space, the user is prompted to create free space by means such as displaying a predetermined message on the display unit 15, and free space securing processing from the user is accepted (step S908). If it is determined that the free space is secured (or has been), a content data transfer request is transmitted to the recording / playback apparatus 30 (step S909).

  When receiving the content data transfer request from the display device 10, the recording / playback device 30 determines whether the connection to the display device 10 is an HDMI cable connection or a network connection (step S910). In such a case, the compressed content data stored in the storage unit 34 is superimposed on the blanking period by the superimposing unit 38 (step S911), and the superimposed compressed content data is transmitted to the display device 10 (step S912).

  When receiving the input signal from the recording / reproducing device 30, the display device 10 determines whether or not the input is via the HDMI cable (step S913). If it is determined that the input is via the HDMI cable, the separation unit 18 separates the compressed content data superimposed in the blanking period (step S914), and determines that the input is via the network, not via the HDMI cable. If it is, the compressed content data is extracted from the IP packet, and the extracted compressed content data is stored in the memory card inserted in the memory card slot 20 based on the control of the control unit 21 (step S915). When the compressed content data is stored in the memory card, a storage processing end notification message is displayed on the display unit 15 (step S916).

  In this way, the content data stored in the recording / playback device is transferred to an external storage medium such as a memory card inserted into the memory card slot of the display device, so that the recording / playback device is in another room. In addition, the content on the recording / playback device can be transferred to the external storage medium on the display device via the display device that is directly operated by the user, and the user can bother to install or remove the external storage medium. No need to move.

  Further, when the display device and the recording / playback device are connected by an HDMI cable, the compressed data stored in the recording / playback device is transferred to the display device so as to be superimposed on the data island period of the blanking period. Since the compressed data is separated by the compressed data, the compressed data can be transmitted even on the HDMI cable that is originally used for transmitting the uncompressed data. It can be stored in an external storage medium as it is.

  In addition, information on portable devices often used by the user is stored in advance in the format storage unit of the recording / playback device as information on the devices used, together with information on the format, and content format conversion processing is performed at the start of recording, free time, etc. As a result, it is not necessary to perform format conversion processing when content data is actually transferred, and time can be saved.

  In addition, when there are a plurality of types of formats stored in the format storage unit of the recording / playback apparatus, the content data is converted into a plurality of types of formats and stored in the storage unit. Even when the user wants to browse with portable devices that use different formats, it is not necessary to perform format conversion processing each time.

  Furthermore, even compressed content data in a format that cannot be decrypted by the display device can be received by the display device and stored in an external storage device inserted in the memory card slot, so all operations are performed on the display device. It is only necessary to do this, and convenience for the user is improved.

  In the embodiment described so far, the memory card slot is provided on the display device 10 side, but may be provided on the remote controller side. A configuration example of the remote controller in this case is shown in FIG. Both the display device and the recording / playback device can be considered as targets of operation of the remote controller. When the recording / playback device is within the range covered by the remote control signal, the recording / playback device is operated directly. If it is in a room or the like, the recording / playback apparatus may be controlled through an instruction to the display device.
