Description

  The present invention relates to a technology of a playback apparatus that plays back audio signals and video signals recorded on an optical disc.

  CD (Compact Disc), DVD (Digital Versatile Disc), BD (Blu-ray Disc), HD (High Definition) -DVD, etc. are optical discs on which audio signals and video signals are recorded. A reproducing apparatus for reproducing these optical discs must first perform processing (loading) for reading TOC (Table Of Contents) information in the optical disc. After loading, the playback device can play back audio / video signals in the disc.

  Loading often takes several tens of seconds. Meanwhile, the operator continues to wait for loading. This is very troublesome for the operator. In particular, when loading next-generation optical discs such as BD and HD-DVD, the current situation is that they spend more time than DVD and CD. Furthermore, in the case of a playback device compatible with both BD and HD-DVD, it is considered that a longer time is required to determine the disc type.

Means for reducing the annoyance caused by this waiting time have been proposed so far. For example, in Patent Document 1, a plurality of segment indicators are used to indicate the progress of loading to the operator by sequentially lighting the segments in accordance with the disk information reading stage.
Further, in Patent Document 2, a hold sound is output or program content is displayed during a waiting time required for powering on and switching channels in digital broadcasting.
Moreover, in patent document 3, a skit, news, etc. are reproduced | regenerated in a communication karaoke apparatus at the time of power activation and during communication time with a data pace.

  Embodiments according to the present invention will be described below in detail with reference to the drawings. In addition, embodiment shown below is an example and is not limited to this.

  FIG. 1 shows a block diagram of an optical disc reproducing apparatus 10 according to the present embodiment. As shown in FIG. 1, the optical disk reproducing apparatus 10 includes a system controller 12, a turntable 14, a spindle motor 16, a pickup 18, a servo control unit 20, a signal processing unit 22, a memory control unit 24, A RAM (Random Access Memory) 26, an output unit 28, an operation unit 30, an interface 32, and a content storage unit 34 are provided.

  The system controller 12 comprehensively controls the operation of the optical disc playback apparatus 10.

The turntable 14 fixed to the spindle motor 16 mounts the optical disk 11. The servo control unit 20 controls to rotate the spindle motor 16 at a predetermined linear velocity.
The pickup 18 includes a laser diode, an objective lens, etc. (not shown). The optical disk 11 is irradiated with laser light having a predetermined wavelength, and the reflected light is analyzed.
The servo control unit 20 controls a focus servo circuit and a tracking servo circuit (not shown) so that the laser light from the pickup 18 correctly follows the pit row of the optical disk 11 and is focused on the pit.
In addition, the servo control unit 20 reads (loads) the TOC information of the optical disc 11 and determines the type of the optical disc 11.

The pickup 18 is provided with at least two types for DVD reading and CD reading. In addition, a pickup for reading BD and HD-DVD may be provided.
First, a laser beam is irradiated from the DVD reading pickup 18. If it is determined to be a DVD, the DVD is loaded. If it is determined that it is not a DVD, and if it is determined that the CD is to be irradiated with laser light from the CD-reading pickup 18, then CD loading is performed. If it is determined that the disc is not a CD, the optical disc playback apparatus 10 determines that an incompatible optical disc 11 is placed, and a series of disc reading processes is stopped.

  The digital data read by the pickup 18 is input to the signal processing unit 22 after being shaped and amplified by the reproduction amplifier 19. The signal processing unit 22 performs demodulation of digital data read from the optical disc 11, extraction of an error signal such as a focus error signal and a tracking error signal, and a synchronization signal.

  The memory control unit 24 inputs the digital data input from the signal processing unit 22 to the RAM 26, and the RAM 26 stores the input digital data. In addition, the memory control unit 24 controls to output the data stored from the RAM 26.

  The output unit 28 converts the data input from the memory control unit 24 into a predetermined format and outputs the data. For example, when the output format is an analog device, the output unit 28 converts the data into an analog audio signal and an analog video signal and outputs them. Alternatively, if the output unit 28 is in a digital format, the data is converted into a predetermined digital format and output.

  The operation unit 30 includes an operation panel, a remote controller, and the like, and is used by the operator to perform operations for causing the reproduction apparatus to operate as desired, such as reproduction of audio / video data recorded on the optical disc 11. .

  The interface 32 constitutes an interface that can be connected to an external network such as the Internet. As shown in FIG. 2, the optical disc playback apparatus 10 is connected to a content server 50 via a network 40.

  The content server 50 stores various music / video contents. The content server 50 includes up-to-date movie preview content, upcoming movie promotion content, upcoming music promotion content, and the like, and the latest information is regularly updated. The content server 50 is provided, for example, by the manufacturer of the optical disc playback apparatus 10.

  Attribute information is attached to each content, and in this example, information indicating that a movie is about to be released is related to a preview content of a movie that will be released soon, and music related to music promotion content that is about to be released The information which shows that is attached | subjected, respectively.

  Returning to FIG. 1, the content storage unit 34 stores music / video content downloaded from the content server 50. Also, the audio / video data of the content downloaded to the content recording unit is transferred to the signal processing unit 22, and written to and read from the RAM 26 under the control of the system controller 12.

The optical disc playback apparatus 10 is configured as described above. In the following, each operation flow when a DVD disk and a CD disk are inserted into the optical disk reproducing apparatus 10 will be described with reference to FIG.
In the embodiment shown below, when a DVD disc is being loaded, a preview content of a movie that will be released soon will be played back, and when a CD disc is being loaded, a promotional content for music that will be released soon will be played back. It is not limited to this.

  In this embodiment, when the optical disc playback apparatus 10 is turned on, the system controller 12 instructs the content server 50 to download the music / video content stored in the content server 50, and the downloaded content is stored in the content storage unit 34. Processing to be stored in However, content download is optional, such as being performed periodically.

  First, when the DVD disk is placed on the turntable 14 (step S11), the servo control unit 20 controls to start reading (loading) the TOC information of the optical disk 11 (step S12). Then, the servo control unit 20 performs disc type discrimination processing (step S13). When it is determined that the disc is a DVD disc, the servo control unit 20 notifies the system controller 12 of the information “loading state” and the information “insert disc is a DVD disc”.

  Similarly, when a CD disk is placed, the servo control unit 20 notifies the system controller 12 of information indicating “loading state” and information indicating “inserted disk is a CD disk”.

  The system controller 12 reproduces different contents according to the type of the optical disk 11 during loading based on the discrimination information of the mounted optical disk 11 received from the servo control unit 20. Specifically, the system controller 12 stores the type of the optical disc 11 and the content attribute information in association with each other, and selects the content attribute information according to the determined type of the optical disc 11. Next, the system controller 12 selects an arbitrary content in the content storage unit 34 that matches the selected attribute information.

  For example, when the system controller 12 receives information indicating “loading state” and information indicating “insert disc is a DVD disc” from the servo control unit 20, the content storage unit 34 receives the content storage unit 34. Is selected arbitrarily, and an instruction to transfer the audio / video data of the content to the signal processing unit 22 is issued (step S14).

  On the other hand, when the system controller 12 receives information from the servo control unit 20 that “the inserted disc is a CD disc”, the system controller 12 records “soon to be released” recorded in the content storage unit 34 to the content storage unit 34. "Music promotion content" is arbitrarily selected, and an instruction to transfer the audio / video data of the content to the signal processing unit 22 is issued (step S14).

  Although the system controller 12 stores the type of the optical disc 11 and the content attribute information in association with each other, the table indicating the relationship may be stored in the content storage unit 34 and referred to.

  Thereafter, until the loading of the optical disc 11 is completed, the content corresponding to the type of the optical disc 11 stored in the content storage unit 34 is reproduced. Loading takes several tens of seconds, for example, and the operator views the video / audio of the content during that time. Here, for example, the content is composed of general commercial video / audio of about 15 seconds.

  In this way, by automatically selecting and playing back the content to be played before the completion of loading according to the type of the inserted optical disc 11, the operator is more conscious of the played content and depends on the waiting time. Annoyance can be further reduced.

  When the system controller 12 receives a notification that “loading has been completed” from the servo control unit 20, the system controller 12 ends the reproduction of the audio / video file of the content recorded in the content storage unit 34 (step S16). Or you may wait after the completion | finish of reproduction | regeneration of content. Thereafter, the audio / video data recorded on the optical disk 11 is reproduced (step S17).

  As described above, in this embodiment, the optical disc 11 is placed and content such as advertisements according to the type of the optical disc 11 is reproduced while being loaded.

  For example, when a BD or DVD disc is inserted into the playback device, the operator may be aware of the movie. Therefore, a preview content of a movie that will be released soon, a promotion content of a movie that will be released soon, and the like are reproduced during loading after inserting the disc.

  Similarly, for example, when inserting a CD of SACD or CD, it seems that there is consciousness about music. Therefore, the advertisement content of music that will be released soon is reproduced during loading after inserting the disc.

  For this reason, the operator can indulge in the content without spending time between loadings. Moreover, since this content is content according to the type of the optical disk 11 placed by the operator, the operator can be more inclined and avoid troublesomeness due to waiting time.

The above embodiment is merely an example, and various changes and modifications can be made within the scope obvious to those skilled in the art.
For example, in the above-described embodiment, the example in which the content is the advertising content has been described. However, the content is not limited to this, and the content may be any content such as a non-commercial free video.
