In the following description, the secondary display 3 is used as a term including not only an LCD and a touch panel but also a configuration for communication with the primary display side, compression / expansion processing, system control, and the like.

  A video signal to be displayed is supplied to the primary display 2 through the media receiver 5. The video signal is a broadcast signal or streaming data distributed via the Internet. The broadcast signal is received by the antenna 6, and the streaming data is branched by the switch 7 and supplied to the media receiver 5 via a LAN (Local Area Network). A personal computer 8 is connected to the other branch of the switch 7.

Streaming data distributed via the Internet 10 is ADSL (Asymmetric
A digital subscriber line (MODEM) 9 (modulator-demodulator) 9 is input to a WAN (Wide Area Network) side, and a switch 7 is connected to the LAN side of the MODEM 9. ADSL is an example of a broadband connection, and video content may be received via a broadband connection using CATV (cable television), FTTH (Fiber To The Home), or the like. Furthermore, it is also possible to obtain streaming data using IP (Internet Protocol) streaming broadcasting. Normally, audio data is attached to video content.

  The media receiver 5 has two tuners in order to be able to supply separate television broadcast programs for each of the primary display 2 and the secondary display 3. The media receiver 5 transmits a video signal to the secondary display 3 via the wireless LAN access point 11. On the other hand, control data such as a remote control signal can be transmitted from the secondary display 3 to the access point 11, and bidirectional communication is possible. For example, an IEEE (Institute of Electrical and Electronics Engineers) 802.11 wireless system can be used, among which, for example, the 802.11a standard can be used. This standard uses a frequency of 5.2 GHz and can realize a maximum transmission rate of 54 Mbps.

  FIG. 2 shows the configuration of an example of a display system including the primary display 2 and the secondary display 3 in more detail. The primary display 2 includes a relatively large display panel 21 of, for example, 30 inches or more and a driving unit (not shown).

  The media receiver 5 includes a main tuner 22a and a sub tuner 22b for receiving terrestrial waves. Reference numeral 23 is a digital tuner for receiving BS (Broadcasting Satellite) and 110 ° CS (Communicaton Satellite). Although not shown, the tuners 22a and 22b are supplied with the output of the UHF / VHF antenna, and the digital tuner 23 is supplied with the output of the BS / 110 ° CS receiving parabolic antenna. In one embodiment, the main tuner 22 a is used for the primary display 2 and the sub-tuner 22 b is used for the secondary display 3.

  Video signals of the main tuner 22 a and the sub tuner 22 b are supplied to the AV switch 24. An output video signal from the AV switch 24 is input to the image processing unit 25 and the signal processing unit 32. The image processing unit 25 performs image processing for improving image quality such as higher resolution.

  An output signal of the image processing unit 25 is input to the display panel 21 of the primary display 2 via a DVI (Digital Visual Interface) 26 that is a display interface. Although not shown, an image quality adjustment circuit for the display panel 21 is provided in the preceding stage of the DVI 26. Further, when a digital video signal is supplied to the display panel 21, a copy prevention signal for preventing unauthorized copying of broadcast content is also output. For example, HDCP (High band with Digital Content Protection) can be used to prevent copying.

  An output signal of the digital tuner 23 is input to the video decoder 27. For example, the video decoder 27 decodes MPEG2 (Moving Picture Experts Group Phase 2). An HD (HIgh Definition) video signal from the video decoder 27 is supplied to the image processing unit 25 and input to the display panel 21 via the DVI 26.

  The video decoder 27 has a function of outputting an SD (Standard Definition) video signal, for example, 480I (interlaced signal having 480 effective lines) to the signal processing unit 32. Reference numeral 28 denotes a system controller that controls the operations of the primary display 2 and the media receiver 5, and is composed of a CPU (Central Processing Unit). For example, the system controller 28 controls the channel selection state of both the main tuner 22a and the sub tuner 22b, and has information on the current channel selection state of each tuner for control.

Streaming data received via the Internet and HTML (Hypertext Markup Language) content data such as a home page are supplied to the signal processing unit 32 via the LAN 31. In the signal processing unit 32, two DSPs (Digital Signal Processors) 33 and 34 are connected to a bus such as a PCI (Peripheral Component Interconnect) 35, and a controller 36 composed of a CPU is connected to the PCI 35 via a bridge 37. Yes.

The signal processing unit 32 decodes the input streaming data (for example, decoding of MPEG4 (Moving Picture Experts Group Phase 4), Windows (registered trademark) Media Player, RealVideo, etc.)). The decoded video signal is supplied to the image processing unit 25 and displayed on the primary display 2. Therefore, the primary display 2 can display broadcast signals from the main tuner 22a and the digital tuner 23, and can display HTML content and streaming content received via broadband.

  The signal processing unit 32 encrypts the video signal from the sub tuner 22 b and the digital tuner 23, further converts the encrypted video signal into a format that can be transmitted wirelessly, and sends it to the secondary display 3 via the access point 11. Send it out. When the streaming content received via the broadband is displayed on the secondary display 3, the signal processing unit 32 does not perform decoding and remains compressed in the streaming compression format, that is, through the access point 11 in a through state. To the secondary display 3. On the other hand, a control signal such as a remote control signal from the secondary display 3 received by the access point 11 is processed and sent to the system controller 28 on the primary display side. In this case, the decoding process of the streaming content is performed on the secondary display 3.

  The secondary display 3 includes a transceiver 41 that performs wireless communication with the access point 11, and a signal processing unit 42 is connected to the transceiver 41. The signal processing unit 42 is configured such that a system controller 43 that controls the operation of the secondary display 3 and a DSP 44 are connected via a PCI 45.

  A display panel such as an LCD 46, a transparent touch panel 47 laminated on the screen of the LCD 46, a speaker 48, and a memory card 49 are connected to the signal processing unit 42. Furthermore, a battery 50 as a power source is provided. The battery 50 can be charged by, for example, a charging circuit housed in the cradle 4 (see FIG. 1). The signal processing unit 42 decrypts the encrypted video signal received from the access point 11, decrypts the data received via the Internet, and displays the decrypted signal on the LCD 46. Further, remote control signals, commands, etc. generated by operating the touch panel 47 are transmitted to the primary display 2 side. Further, it has a function of decoding still image data stored in the memory card 49 and displaying it on the LCD 46.

  The operation of the display system according to the embodiment of the present invention described above will be described below. The baseband analog video signal demodulated by the main tuner 22a is converted into a digital signal, which is subjected to image quality improvement processing and interlace / progressive conversion processing by the image processing unit 25, and then displayed via the DVI 26. Output to the panel 21.

  The baseband analog signal demodulated by the sub-tuner 22b is supplied to the signal processing unit 32, converted into a digital signal, and then compressed in a digital compression format such as MPEG2 or MPEG4. The compressed video signal is transmitted to the secondary display 3 by the wireless LAN through the access point 11 after being subjected to the encryption process. The signal processing unit 42 of the secondary display 3 receives the decryption and decompression processing of the encryption, and is displayed on the LCD 46.

  When the input source is a digital broadcast signal, the digital broadcast signal is input to the digital tuner 23, demodulated by the digital front end block of the digital tuner 23, and then decoded by the video decoder 27. The digital video signal is displayed on the display panel 21 via the image processing unit 25 and the DVI 26.

  An SD signal, for example, a 480I video signal output from the video decoder 27 is sent to the signal processing unit 32, and is compressed and encrypted in the digital compression format by the signal processing unit 32. Then, it is transmitted from the wireless LAN access point 11 to the secondary display 3. When the input source is an HD signal, it is down-converted to an SD signal, for example, a 480I video signal, and then sent to the signal processing unit 32. Down-conversion is a process performed for copyright protection of digital broadcast content.

When the input source is streaming content from the Internet, the signal input from the LAN 31 is subjected to streaming decoding processing in the signal processing unit 32 according to the streaming compression format (MPEG4, Windows (registered trademark) Media Player, RealVideo, etc.). The image data is sent to the display panel 21 via the image processing unit 25 and the DVI 26.

  Further, when displaying streaming content on the secondary display 3, the signal processing unit 32 does not receive the decoding process and remains compressed in the streaming compression format, with respect to the secondary display 3 by the wireless LAN. Sent out. Then, decoding processing of streaming compression is performed by the signal processing unit 42 of the secondary display 3, the decoded video is displayed on the LCD 46, and the decoded audio is reproduced by the speaker 48. By this process, it is possible to prevent the content from being deteriorated due to the decoding and re-encoding process of the streaming content.

In the receiving system according to the embodiment of the present invention, copyright protection is performed as described below. First, regarding the content of an analog broadcast signal, if the content restricts analog copying, the signal processing unit 32 digitally compresses the content before sending it to the secondary display 3, and as a content protection measure, encryption methods for example D ES (Data encryption Standard), is encrypted by AES (Advanced encryption Standard) or the like. For example, when a macrovision copy restriction signal is added to an analog video signal, analog copy is restricted.

Further, as a protection measure for the transmission system, encryption on the transmission path is performed by an encryption method used in wireless LAN transmission. For example, RC4 ((Rivest Cipher) 4 Stream Cipher) is used in a wireless LAN (IEEE 802.11), and WEP (Wired Equivalent Privacy protocol) is used as an encryption key generation algorithm. In WEP, an encryption key is generated from an IV (Initial Vector) and a common key, and network packets are encrypted. In this way, the first encryption for the content protection measure and the second encryption for the protection measure for the transmission system are applied to the content of the analog broadcast signal.

  On the secondary display 3 side, authentication is performed through communication with the primary side, and then the encryption on the transmission path is decrypted by the wireless LAN transceiver 41, and further, the signal processing unit 42 performs content protection. The encryption is decrypted. When the secondary display 3 has an analog recording function, it is possible to limit recording before recording by detecting a macrovision signal. Further, when the secondary display 3 has an external output interface, copy restriction can be similarly applied to an external recording device by outputting an analog video signal with a macrovision signal added.

Next, copyright protection for digital broadcast signal contents will be described. In one embodiment, an example one of the digital tuner 23 are al provided. In this example, there is one conditional access mechanism having a copyright protection function (specifically, one IC card), and the data decrypted by the digital tuner 23 is sent to the video decoder 27. And output to the primary display 2. The conditional access mechanism depends on the number of digital tuners. In order to simultaneously view different digital broadcast contents on the primary display 2 and the secondary display 3, two digital tuners each having a conditional access mechanism may be provided.

  Further, as described above, when the content of the digital broadcast signal is viewed on the secondary display 3, the analog signal once decoded by the video decoder 27 is sent without sending the digitally compressed signal to the secondary display 3. Is transmitted to the signal processing unit 32, and the signal processing unit 32 re-encodes the signal using a compression method suitable for home transmission. The data is sent to the secondary display 3 after double encryption with encryption for protection. In the case of digital broadcast HD content, since it is downconverted to 480I SD content and sent to the secondary display 3, the copyright of the HD content can be substantially protected even if the encryption is decrypted. it can. In this way, copyright protection of content transmitted between the media receiver 5 (primary display 2) and the secondary display 3 can be achieved with high security.

  Information related to television broadcast programs, such as synopsis about drama, performers, etc. can be viewed on a predetermined URL (Uniform Resource Locator) site on the Internet. The system controller 28 of the media receiver 5 on the primary display side has channel selection information regarding the current channel selection state of the main tuner 22a in order to control the main tuner 22a. This channel selection information is sent to the system controller 43 of the signal processing unit 42 of the secondary display 3.

  The secondary display 3 is equipped with a browser for browsing and displaying Internet information and a database indicating the correspondence between programs and URLs. Channel selection information received from the primary display 5, such as the channel selection channel and current time information, shows the program being viewed, and the URL of the related site of the program is known from the database. Then, the site is accessed via the Internet 10 and related information of the program being viewed is acquired and displayed on the secondary display 3. That is, related information of the broadcast program being viewed can be displayed on the LCD 46 of the secondary display 3 while displaying the broadcast program on the large display panel 21 of the primary display. Since the related information is not displayed on the screen of the display panel 21, there is no possibility that the viewing of the program is hindered by the related information, and since the related information is viewed on the LCD 46 at hand, small characters can be easily seen.

  Note that a signal necessary for accessing related information included in a broadcast signal may be detected, and a related information site may be accessed based on the detected signal. For example, a data signal serving as a trigger when a program is transmitted from a broadcasting station may be transmitted, and the URL of the related site may be automatically detected by detecting this data signal.

  In the display system described above, selection of a broadcast program to be viewed and selection of Internet content are performed by a GUI (Graphical User Interface) using the touch panel 47. On the touch panel 47, a desired content can be selected by a touch and release operation, that is, a single operation.

  FIG. 3 shows a selected display, for example, a menu display 54 displayed when the finger 52 (or touch pen) touches the sensor unit 51 b on the right side of the touch panel 47. When the finger 52 is moved up and down while touching the sensor unit 51b, only the menu item having the same height as the finger 52 is highlighted. FIG. 5 shows a state where the channel list of the menu item is highlighted.

  Then, when the finger 52 is released at the position of the highlighted menu item, the menu item is selected. A lower-level screen corresponding to the selected menu item is displayed. Although omitted in FIG. 3, when the menu display 54 is displayed, the image on the LCD 46 of the secondary display 3 is displayed on the display / sensor unit 51 a of the touch panel 47.

  Note that if the position of the finger 52 is on the sensor unit 51b but there is no menu item on the side, the menu item is not highlighted. That is, when an area above or below the area where the six menu items are arranged is touched, no button is highlighted because there is no adjacent button. In this state, when the finger is released from the sensor unit 51b, it is determined that the selection action has been canceled, the process ends, the state does not change, and the menu display 54 continues to be displayed.

  Further, when the finger 52 is shifted to the display / sensor unit 51a having a size substantially equal to the display surface of the LCD 46, it is determined that the selection action has been canceled, the processing ends, and the menu display 54 disappears. . In this case, even if the finger 52 is subsequently released from the touch panel 47, the state does not change.

  FIG. 4 is an example of the display 55 when the menu item “TV channel list” is selected. The terrestrial, BS, CS, and input (video 1 to video 4) channels are displayed on the LCD 46, and a desired channel can be selected by the display / sensor unit 51a of the touch panel 47. The channel list of FIG. 4 is a list display indicating what is displayed on the primary display 2, for example.

  FIG. 5 shows an example of the display 56 when the “channel list” menu item is selected. This shows a list of all contents that can be viewed on the secondary display 3. In addition to the television channel and video input for viewing the television broadcast content shown in FIG. 4, there are channels such as news received via the Internet and streaming content received via broadband. A desired channel can be selected by the display / sensor unit 51 a of the touch panel 47 displayed on the LCD 46.

  As in the example of the display 56 of FIG. 5, by displaying all the lists of receivable sources on the LCD 46 of the secondary display 3 in a centralized manner, it is possible to perform a single selection operation without distinguishing between television broadcasting and the Internet. Desired content can be selected. In other words, it is possible to seamlessly select broadcast content and network distribution content including images and sounds such as moving images and still images.

A remote control button is displayed on the screen of the LCD 46, and the primary display 2 and the media receiver 5 can be controlled by pressing a desired button on the display / sensor unit 51a of the touch panel 47. The buttons for the remote control are buttons such as a numeric keypad, volume increase / decrease, and channel switching. Thus, since the secondary display 3 has a function as a remote control commander, it is not necessary to prepare a separate commander, and it is possible to prevent the number of commanders from increasing in the home. In addition to remote control of the primary display 2, a remote control mode for AV equipment such as recording equipment may be prepared.

  Although not shown, when the menu item “Memory Stick (product name)” is selected, the display when the menu item “Internet” is selected, and when the menu item “setup” is selected. A corresponding display is displayed on the LCD 46.
