20120014664
This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2010-162164, filed Jul. 16, 2010; the entire contents of which are incorporated herein by reference.
Embodiments described herein relate generally to a recording control apparatus and a recording control method, which execute control to record input data.
In recent years, a recording/reproducing apparatus, which can record and reproduce digital TV broadcast, have been gaining in popularity. This recording/reproducing apparatus can record digital TV broadcast in a hard disk drive (HDD) or a digital versatile disk (DVD).
Further, there has been proposed a recording/reproducing apparatus which can record digital TV broadcast in a card-type recording medium such as an SD memory card. By recording video content in an SD memory card by this recording/reproducing apparatus, it becomes possible to reproduce the video content recorded in the SD memory card by an external device, such as a mobile terminal, which supports SD memory cards.
In the above-described recording/reproducing apparatus, video content is recorded in the SD memory card by a pre-designated data format. If the external device does not support the designated data format, the external device cannot reproduce the video content recorded in the SD memory card.
In order to avoid this situation, for example, the user checks the adaptive data format which is adaptive to the external device, and sets up the recording/reproducing apparatus so as to record the video content in the SD memory card by the adaptive data format. This setup operation is time-consuming for the user. Besides, this setup operation is difficult for users who are not familiar with data formats.
A general architecture that implements the various features of the embodiments will now be described with reference to the drawings. The drawings and the associated descriptions are provided to illustrate the embodiments and not to limit the scope of the invention.
Various embodiments will be described hereinafter with reference to the accompanying drawings.
In general, according to one embodiment, a recording control apparatus includes a setup module and a controller. The setup module is configured to set, in accordance with designation of a device, an adaptive data format which is adaptive to the device. The controller is configured to execute control to record input data by the adaptive data format.
First to fourth embodiments will now be described with reference to the accompanying drawings.
As shown in
The control module 104 controls an operation of recording a program and an operation of reproducing a program. In addition, the control module 104 controls execution of a device-adaptive recording process which will be described later. The communication module 103 can be connected to a server 202 via a network 201, and can transmit various information to the server 202 and receive various information from the server 202. The tuner module 105 selects a broadcast signal of a designated channel, and inputs the selected broadcast signal to the recording/reproducing signal processing module 108.
When a recording process is designated, the recording/reproducing signal processing module 108 inputs program content data (video signal and audio signal) corresponding to the broadcast signal to at least one of the disk drive module 110, hard disk drive module 111 and media interface 112.
The disk drive module 110 records input program content data on an optical disk D, such as a DVD or a BD (Blu-ray) (trademark), in a standard data format (default data format) which is adaptive to a medium that is a target of recording. Specifically, when program content data is recorded on a DVD, the disk drive module 110 records the program content data on the DVD by a predetermined data format (standard data format) which is adaptive to DVD specifications. When program content data is recorded on a BD, the disk drive module 110 records the program content data on the BD by a predetermined data format (standard data format) which is adaptive to BD specifications.
Similarly, the hard disk drive module 111 records input program content data in a hard disk by a standard data format (default data format) which is adaptive to a medium that is a target of recording.
The media interface 112 records, according to the device-adaptive recording process, input program content data in media (e.g. an SD card 301) by a device-adaptive data format. The device-adaptive recording process will be described later in detail.
For example, a mobile terminal 302 includes a media slot for the SD card 301, and the mobile terminal 302 supports one or a plurality of data formats. Hereinafter, a data format which is supported by the mobile terminal 302 is referred to as “support data format”. Specifically, the mobile terminal 302 can reproduce program content data of a support data format, which is recorded in the SD card 301, but cannot reproduce program content data of a non-support data format, which is recorded in the SD card 301.
When a reproduction process is designated, the recording/reproducing signal processing module 108 outputs program content data corresponding to a broadcast signal to a video display device M (digital TV) including a speaker or the like, via the mixing process module 109.
Next, an example of various operations through a remote-controller 102a is described. Various operations through the user operation input module 101 are substantially identical to various operations through the remote-controller 102a, and thus a description of the former is omitted.
The remote-controller 102a includes a plurality of keys, and transmits instructions which are input through these keys. The signal light-reception module 102 receives an instruction from the remote-controller 102a, and notifies the instruction to the control module 104.
Next, the device-adaptive recording process is described.
To begin with, referring to
For example, if the remote-controller 102a transmits a display instruction for displaying the device-adaptive format select OSD screen, in accordance with the user's operation of the remote-controller 102a, the control module 104 receives, via the signal light-reception module 102, the display instruction for displaying the device-adaptive format select OSD screen, and a screen generation module 1041 controls the generation of the device-adaptive format select OSD screen.
The screen generation module 1041 controls the generation of the device-adaptive format select OSD screen, based on device-adaptive format select OSD screen generation information which is stored in the memory module 106. The communication module 103 can download the latest device-adaptive format select OSD screen generation information from the server 202 via the network 201. Thereby, the memory module 106 can store the latest device-adaptive format select OSD screen generation information.
A screen display/select accept module 1042 controls the display of the device-adaptive format select OSD screen. The OSD control module 107 generates the device-adaptive format select OSD screen, based on the device-adaptive format select OSD screen generation information, and outputs the device-adaptive format select OSD screen to the mixing process module 109. Based on the OSD control of the OSD control module 107, the mixing process module 109 can output only the video of the device-adaptive format select OSD screen, can output video in which the video of the device-adaptive format select OSD screen is superimposed on the video of a predetermined program, or can output the video of a predetermined program and the video of the device-adaptive format select OSD screen. Thereby, the video display device M displays the device-adaptive format select OSD screen.
As shown in
Following the above, an adaptive-format registration module 1043 refers to a correspondency table stored in the memory module 106, searches an adaptive data format which corresponds to the designated device (model number), and sets the adaptive data format which corresponds to the designated device (model number) (Yes in BLOCK 102) (BLOCK 103).
Thus, when the designated device (model number) is the terminal A (device A), the adaptive-format registration module 1043 refers to the correspondency table stored in the memory module 106, and sets the format A. When the designated device (model number) is the terminal B (device B), the adaptive-format registration module 1043 refers to the correspondency table stored in the memory module 106, and sets the format B. When the designated device (model number) is the terminal C (device C), the adaptive-format registration module 1043 refers to the correspondency table stored in the memory module 106, and sets the format C.
If the memory module 106 does not store the correspondency table (No in BLOCK 102), or if the correspondency table stored in the memory module 106 is old (i.e. if the correspondency table has not been updated for a period longer than a predetermined period), an expansion table acquisition module 1044 downloads a correspondency table (expansion table) from the server 202 via the communication module 103 (BLOCK 104), and updates the correspondency table in the memory module 106 to the latest correspondency table. Thereby, the adaptive-format registration module 1043 can refer to the latest correspondency table stored in the memory module 106, and can search and set an adaptive data format which corresponds to the designated device (model number), and sets the adaptive data format which corresponds to the designated device (model number) (BLOCK 103).
Alternatively, when the memory module 106 does not store the correspondency table (No in BLOCK 102), the adaptive-format registration module 1043 sets a default format (BLOCK 104).
In the above description, the case has been described in which the number of adaptive data formats, which correspond to the designated device, is one. However, the number of adaptive data formats, which correspond to the designated device, may be two or more.
Next, a first data recording process by the adaptive data format is described.
In accordance with the user's instruction for program recording, the control module 104 executes a first data recording process by an adaptive data format. Specifically, an adaptive format data recording/output module 1045 executes control to record input data (video stream data) by an adaptive data format. Thus, simply by the user designating the device (e.g. mobile terminal 302) in advance, as described above, the adaptive format data recording/output module 1045 executes control to record content in a designated medium (SD card 301) by an adaptive data format which is supported by the designated device (e.g. mobile terminal 302).
In accordance with this, the recording/reproducing signal processing module 108 converts the content data to the adaptive data format, and outputs the content data of the adaptive data format to, e.g. the SD card 301. Thus, the content data of the adaptive data format is recorded in the SD card 301.
For example, simply by loading the SD card 301 in the mobile terminal 302, the user can surely view, with the mobile terminal 302, the content data (the content data of the adaptive data format) which is recorded in the SD card 301.
In the above description, the case has been described in which the content data of the adaptive data format is recorded in the SD card 301. Alternatively, the content data of the adaptive data format may be recorded on the hard disk. In this case, for example, the video recording/reproducing apparatus 1 and the mobile terminal 302 are connected by, e.g. a USB, and the content data of the adaptive data format, which is recorded on the hard disk of the video recording/reproducing apparatus 1, can be copied or moved from the video recording/reproducing apparatus 1 to the mobile terminal 302 by an operation such as a drag-and-drop operation.
In this case, too, by a simple operation such as a drag-and-drop operation, the user can surely view the content data (the content data of the adaptive data format) by the mobile terminal 302.
In the above description, the case has been described in which the recording/reproducing signal processing module 108 converts the content data to one adaptive data format, and records the converted content data of the adaptive data format. Alternatively, when a plurality of adaptive data formats are set, the recording/reproducing signal processing module 108 may convert the content data to the plural adaptive data formats, and records the converted content data of the plural adaptive data formats.
In the meantime, after content data is recorded by a standard data format (default data format), the device designation process and the first adaptive data format setup process may be executed, and thereafter the first data recording process may be executed. Specifically, in accordance with the user's instruction for program recording, the control module 104 executes control to record the content data by the standard format (first data format). In accordance with this, for example, the hard disk drive module 111 records the content data of the standard data format on the hard disk. Subsequently, if the device designation process is executed, the first adaptive data format setup process is executed, the first data recording process is executed, the content data of the standard data format (first data format) recorded on the hard disk is converted to content data of the adaptive data format (second data format), and the converted content data of the adaptive data format is recorded.
In the first embodiment, the first data recording process, which records content data by the adaptive data format, has been described. In the second embodiment, a description is given of a second data recording process which records content data by both the standard data format (first data format) and the adaptive data format (second data format).
As shown in
In accordance with this, the recording/reproducing signal processing module 108 converts the content data to the standard data format, and the hard disk drive module 111, for example, records the content data of the standard data format on the hard disk. Further, the recording/reproducing signal processing module 108 converts the content data to the adaptive data format, and the hard disk drive module 111, for example, records the content data of the adaptive data format on the hard disk (BLOCK 301) (BLOCK 302).
Alternatively, the recording/reproducing signal processing module 108 converts the content data to the standard data format, and the hard disk drive module 111, for example, records the content data of the standard data format on the hard disk. Further, the recording/reproducing signal processing module 108 converts the content data to the adaptive data format, and outputs the content data of the adaptive data format to the SD card 301.
When the content data of the adaptive data format is recorded on the hard disk, the recording/reproducing signal processing module 108 transfers the content data of the adaptive data format, which is recorded on the hard disk, to the SD card 301, for example, in accordance with a data transfer instruction by the user (BLOCK 303). Accordingly, the content data of the standard data format is recorded on the hard disk, and the content data of the adaptive data format is recorded in the SD card 301. In the meantime, it is assumed that the recording/reproducing signal processing module 108 can reproduce recorded data which is recorded, at least, by the standard data format.
For example, simply by loading the SD card 301 in the mobile terminal 302, the user can surely view, with the mobile terminal 302, the content data (the content data of the adaptive data format) which is recorded in the SD card 301 (BLOCK 304). Moreover, the user can view, with the video recording/reproducing apparatus 1, the content data (the content data of the standard data format) which is recorded in the hard disk drive.
In the second embodiment, the second data recording process, which records content data by both the standard data format (first data format) and adaptive data format (second data format), has been described. In the third embodiment, a description is given of a third data recording process which records content data by the standard data format (first data format) and the adaptive data format (second data format) at the same timing, and a fourth data recording process which records content data by the standard data format (first data format) and the adaptive data format (second data format) at different timings.
As described above, the control module 104 executes the third data recording process by the standard data format and adaptive data format. For example, the adaptive format data recording/output module 1045 executes control to record content data by both the standard data format and the adaptive data format at the same timing. Thereby, immediately after the recording of the content data, the content data of the adaptive data format can be used.
Alternatively, the control module 104 executes the fourth data recording process by the standard data format and adaptive data format. For example, the adaptive format data recording/output module 1045 executes control to record content data by both the standard data format and the adaptive data format at different timings. For example, the adaptive format data recording/output module 1045 preferentially executes the recording of content data by the standard data format, and executes, after the completion of the recording of content data by the standard data format, the recording of content data by the adaptive data format. For example, the adaptive format data recording/output module 1045 executes the recording of content data by the adaptive data format in a designated time zone (late-night time zone). Thereby, even if the processing capability of the recording/reproducing signal processing module 108, etc. is low, it becomes possible to record the content data by a plurality of adaptive data formats. Moreover, since the recording/reproducing signal processing module 108 has an excess capability while recording the content data of the standard data format, the recording/reproducing signal processing module 108 can execute a parallel process, such as reproducing other content data.
Aside from the above, content data of an adaptive data format may be prepared in a manner as described below. For example, if the control module 104 detects, for example, additional recording of new content data (content data of the standard data format), the adaptive format data recording/output module 1045 may generate and record content data of an adaptive data format corresponding to the new content data. Thereby, both the standard data format and the adaptive data format are prepared for all content data, and the convenience is enhanced.
In the first embodiment, the first adaptive data format setup process corresponding to the designation of the device has been described. In the fourth embodiment, a description is given of a second adaptive data format setup process corresponding to the designation of the device and the designation of the data format.
For example, in the case where the device A has been designated through the device-adaptive format select OSD screen shown in
In the meantime, the adaptive-format registration module 1043 may preferentially (automatically) set either the format A1 or the format A2. In other words, even in the case where the user has designated the device A, and the device A supports the format A1 and format A2, the adaptive-format registration module 1043 preferentially (automatically) sets either the format A1 or the format A2.
According to the above-described first to fourth embodiments, simply by the user designating a device on the GUI screen, the video recording/reproducing apparatus 1 sets the adaptive data format which is adaptive to the designated device, converts content data to the adaptive data format, and records the content data of the adaptive data format. Specifically, the video recording/reproducing apparatus 1 does not record content data by converting the content data to a designated data format, but the video recording/reproducing apparatus 1 records content data by converting the content data to an adaptive data format which is adaptive to a designated device. Even if the user is not familiar with data formats, it is possible to obtain data of an adaptive data format which is adaptive to a device that is to be used by the user.
In the above-described first to fourth embodiments, the transcode by the video recording/reproducing apparatus 1 has been described. However, for example, the video recording/reproducing apparatus 1 can re-encode MPEG2 content data of BS/CS broadcast to content data of MPEG4AVC for smartphones.
The first to fourth embodiments may be summarized as follows.
(1) The video recording/reproducing apparatus 1 can convert, at the same timing, content data to the standard data format (first data format) and the adaptive data format (second data format) that is adaptive to the designated device, and can record, at the same timing, the content data of the standard data format and the content data of the adaptive data format.
(2) The video recording/reproducing apparatus 1 can convert, at different timings based on a predetermined event, content data to the standard data format (first data format) and the adaptive data format (second data format) that is adaptive to the designated device, and can record, at different timings based on a predetermined event, the content data of the standard data format and the content data of the adaptive data format.
Thus, for example, when the user possesses a smartphone, the user can obtain content data of an adaptive data format which is reproducible by the smartphone, simply by designating this smartphone in the video recording/reproducing apparatus 1. In other words, the video recording/reproducing apparatus 1 records content data by an adaptive data format which is supported by a designated smartphone. The content data of the adaptive data format, which has been recorded by the video recording/reproducing apparatus 1, can be moved to the smartphone by wire, or wirelessly, or via recording media. Thereby, the content data can surely be viewed by the smartphone.
