- the memory 204 is assumed to be a DRAM.
- the memory 204 may not be a DRAM, and other recording media such as a flash memory may be used. At this time, it is not necessary to always energize the flash memory.
- the memory 204 is configured by a flash memory, there is no need to separately provide a buffer memory as in Patent Document 1.
- the storage area of the memory 204 is divided into a plurality of uses. Specifically, the storage area of the memory 204 is divided into a work memory 301, a recording list application rendering buffer 302, a program guide application rendering buffer 303, and a frame buffer 304.
- the rendering buffers 302 and 303 may be called.
- the total capacity of the memory 204 is, for example, 512 megabytes (MB).
- the work memory 301 has a capacity of 488 MB
- the rendering buffers 302 and 303 each have a capacity of 8 MB
- the frame buffer 304 has a capacity of 8 MB.
- the work memory 301 is used to develop a computer program when the recorder 101 operates based on the computer program, and temporarily store data necessary for the operation.
- an application program for displaying a recording list (recording list application) program and an application program for displaying a program guide (program guide application) will be described as computer programs. These programs are stored in the HDD 203.
- the LSI 202 is a computer represented by a semiconductor processor or the like. The LSI 202 reads a program from the HDD 203, loads it into the work memory 301, and executes the program.
- the recording list application rendering buffer 302 is used to temporarily store image data for displaying a list of recorded programs. This image data is generated by a recording list application.
- the program guide application rendering buffer 303 is used to temporarily store image data for displaying a list of program guides. This image data is generated by the program guide application.
- the program guide application has a function of making a recording reservation for a program.
- the frame buffer 304 stores image data to be output to a display device such as a television. For example, when outputting an image of a recording list or an image of a program guide to the television 102, the LSI 202 transfers the image data stored in the rendering buffers 302 and 303 to the frame buffer 304, and the image data is transferred to the frame buffer. The data is output from 304 to the television 102 via the HDMI terminal 205.
- FIG. 4 is an external view of the remote control 103 according to the present embodiment. As illustrated, the remote control 103 is provided with various buttons. Among these, in this embodiment, five buttons to which reference numerals are attached will be described.
- the remote control 103 has a power button 405, a recording list button 401, a program guide button 402, a submenu button 403, and a playback button 404.
- the power button 405 is used for turning on or off the power of the recorder 101.
- a recording list button 401 is used to start a recording list application and display a list of recorded programs.
- the program guide button 402 is used to start the program guide application and display the program guide.
- the submenu button 403 is used to execute a recording program editing process on the recording list application.
- a play button 404 is used to play a recorded program selected on the recording list application.
- FIG. 5 is a flowchart for explaining the transition from power on to power off of the recorder 101 according to the present embodiment.
- the LSI 202 When the recorder 101 is powered on (S501), the LSI 202 receives a power-off instruction by pressing the power button 405 of the user's remote control 103 (Yes in S502), and the video / audio signal from the HDMI terminal 205 is received. The output is stopped (S503), and the energization of the HDD 203 is stopped (S504). As a result, the above-described power-off state is entered. However, the LSI 202 and the memory 204 continue processing.
- the LSI 202 activates the recording list application, generates image data of the recording list using the recorded program information table temporarily stored in the memory 204, and stores the image data in the rendering buffer 302 ( S505). Details of the recorded program information table will be described later.
- the LSI 202 stores the image data in the rendering buffer 302, then starts the program guide application, generates image data of the program guide using control data separately stored in the memory 204, and sends the image to the rendering buffer 303.
- the data is stored (S506).
- control data is superimposed on the broadcast wave.
- program arrangement information SI Service Information
- the LSI 202 may obtain control data from the Internet.
- the recorder 101 shown in FIGS. 1 and 2 does not clearly indicate that it is connected to the network. However, for example, by further providing the recorder 101 with a communication interface described in FIG. 16 to be described later, the recorder 101 can acquire control data from the Internet.
- the program guide application generates a program guide using the above-described program arrangement information SI or control data acquired from the Internet.
- the image data of the recording list and the program guide described above are stored in the rendering buffers 302 and 303 as color data for each unit constituting the image (for example, RGB value data for each pixel). By storing such data in the rendering buffers 302 and 303, it is possible to speed up image display.
- the LSI 202 turns on the LED in red (S507), and continues to wait for an instruction from the remote controller 103 (S508). Then, the LSI 202 stops supplying power to the TV tuner 201 and the HDD 203. As a result, the recorder 101 is turned off. Note that the supply of power to the memory 204 including the rendering buffers 302 and 303 is continued. Although the application resides in the work memory 301, the application has stopped its operation at this point. The recorder 101 transits from power-on to power-off by the above processing. When a predetermined operation is performed after the power is turned off, processing shown in a flowchart of FIG. 7 described later is executed.
- FIG. 6 is an example of the recorded program information table 600 according to the present embodiment.
- the recorded program information table 600 is referred to when the recording list application generates and displays an image.
- the program name of the recorded program, the recording date and time, the channel number, the file path to the thumbnail image, and the file path to the video data are described. These data are called metadata or control data.
- the metadata is all attribute information related to the program, and includes data other than the data described in the recorded program information table 600.
- the LSI 202 of the recorder 101 stores the video data of the recorded program and all metadata related to the program in the HDD 203.
- the recording list application extracts the minimum metadata necessary for displaying the images of the recording list, and temporarily stores the metadata as a recorded program information table 600 on the work memory 301 in the memory.
- Transition from Power Off to Power On FIG. 7 is a flowchart for explaining a transition from power off to power on of the recorder 101 according to this embodiment.
- the process of this flowchart is performed after the process of the flowchart shown in FIG. Therefore, in this flowchart, the power-off state (S508), which is the final state of the flowchart of the transition from power-on to power-off in FIG. 5, is set as the initial state.
- the recorder 101 turns on the power of the recorder 101 and displays the program guide. Specifically, when detecting the pressing operation of the program guide button 402 of the remote controller 103, the LSI 202 determines that there is an instruction to display the program guide (S901). The LSI 202 transfers the image data 800 from the program guide application rendering buffer 303 to the frame buffer 304 (S911). The LSI 202 outputs image data from the frame buffer 304 using the HDMI terminal 205 (S912).
- the LSI 202 turns off the LED (S913), starts energization of the HDD 203 (S914), and ends the recording list application when the recording list application is executed (S915). This process is performed for the purpose of avoiding pressure on the capacity of the work memory 301. This is not necessary if the capacity of the work memory 301 is sufficiently large.
- the program guide application is in an execution state and the program guide is displayed (S916).
- FIG. 8A shows an example of a program guide 800a displayed after the program guide button 402 is pressed.
- the startup process of the HDD 203 has not been completed yet. For this reason, information that cannot be acquired unless the startup process of the HDD 203 is completed, for example, information on the remaining recording time that can be recorded cannot be displayed on the HDD 203.
- FIG. 8A shows an area 8a where information on the remaining recording time is to be displayed. It is understood that nothing is displayed in the area 8a.
- thumbnail video is displayed in a part of the leftmost column of the image 800 in the program guide.
- This thumbnail video is an image of a program being broadcast acquired by the TV tuner 201. Since the TV tuner 201 is activated faster than the HDD 203 from the power-off state, the thumbnail moving image is also displayed soon after the program guide is displayed. At this time, the startup process (spin-up process) of the HDD 203 is not completed.
- the process proceeds to step S917.
- the program guide application reads information about the HDD 203 from the HDD 203 (for example, information on the remaining time that can be recorded in the HDD 203), and updates the program guide already displayed.
- FIG. 8B is an example of a program guide image 800b whose display is updated.
- image 800 information 8b of the remaining time that can be recorded in the HDD 203 is displayed.
- the program guide image 800a (FIG. 8A) can be generated by the program guide application.
- Information that cannot be displayed without waiting for completion of the activation process of the HDD 203 is acquired from the HDD 203 after the completion of the activation process, and the image of the program guide is updated (FIG. 8B).
- the recorder 101 When the pressing of the recording list button 401 is detected when the power is turned off, the recorder 101 turns on the power and displays the recording list. Specifically, when detecting the pressing operation of the recording list button 401 of the remote controller 103, the LSI 202 determines that there is an instruction to display the recording list (S901). The LSI 202 transfers the data of the image 700 from the recording list application rendering buffer 302 to the frame buffer 304 (S921), and outputs the image data from the frame buffer 304 via the HDMI terminal 205 (S922). Further, the LSI 202 turns off the LED (S923), starts energizing the HDD 203 (S924), and ends the program guide application when the program guide application is executed (S925).
- This process is also performed for the purpose of avoiding pressure on the work memory 301. If the capacity of the work memory 301 is sufficiently large, it is not necessary. As a result, the recording list application enters an execution state (S926). It should be noted that the spin-up process of the HDD 203 has not yet been completed at the time when the recording list application enters the execution state. Therefore, access to the HDD 203 remains impossible.
- FIG. 9 shows an example of a recording list image 700 displayed when the HDD 203 cannot be accessed. Since the contents of the HDD 203 cannot be referred to, the LSI 202 cannot acquire data that exists only on the HDD 203 or information about the devices of the HDD 203. Specifically, in the present embodiment, the LSI 202 cannot obtain information about the thumbnail image of the recorded program and the remaining recordable amount of the HDD 203 from the HDD 203.
- the recording list image 700 generated by the recording list application information cannot be displayed in the thumbnail area 701 in which thumbnail images are displayed and the area 702 in which the remaining recordable capacity of the HDD 203 is displayed.
- the LSI 202 generates image data in which no information is displayed in the recorded program thumbnail image display area 701 and the HDD remaining capacity display area 702 displayed when the HDD is accessible.
- the user can immediately display and operate a desired application without waiting for the HDD 203 to be accessible after operating the recording list button 401 and the program guide button 402 of the remote controller 301.
- “immediately” means, for example, within one second after the button is pressed.
- power supply to the HDD 203 is stopped when the power is turned off, both power saving and high-speed display can be achieved.
- FIG. 10 is a flowchart for explaining processing according to whether or not HDD access is possible in the recording list application according to the present embodiment.
- the recording list application execution state S926
- S926 which is the final state of the flowchart of the transition from power-off to power-on in FIG. As described above, in this state, access to the HDD 203 is impossible.
- the submenu button 403 is pressed when executing a recording program editing process on the recording list application.
- FIG. 11 shows an image display example of the recorded program list 1100 displayed with the warning panel 1101 superimposed. In FIG. 11, a message “HDD is starting up. Please wait for a while.” Is displayed on the warning panel 1101.
- the LSI 202 discards the editing instruction and enters the instruction waiting state again.
- the “edit instruction” is an object of discarding, but the “edit instruction” is an example.
- the instruction to be discarded may exist other than the “edit instruction”. For example, this is a dubbing start instruction that requires data writing to the HDD 203.
- the instruction to be discarded can be determined in advance.
- the LSI 202 determines that this operation is an instruction to request updating of the program list information (S1003). Then, the LSI 202 refers to the recorded program information table 600 stored in the work memory 301 to generate a recording list image, and transfers the image data to the recording list application rendering buffer 302 and the frame buffer 304 (S1004). .
- the HDD 203 transmits a notification indicating that the spin-up process has been completed to the LSI 202.
- the LSI 202 detects that access to the HDD 203 is possible (S1005).
- the LSI 202 accesses the HDD 203 and obtains information on the remaining recordable capacity of the HDD 203 and thumbnail image data of a recorded program existing on the HDD 203 (S1006).
- the LSI 202 generates image data in which the recorded program thumbnail image display area 1201 and the HDD remaining amount display area 1202 are updated.
- the LSI 202 transfers the image data to the rendering buffer 302 and the frame buffer 304 (S1007).
- the image of the recording list is updated.
- FIG. 12 shows an image 1200 of the updated recording list.
- the LSI 202 updates the display of the area that could not be displayed due to the failure to access the HDD 203, and enables all the functions of the recording list application. As a result, it is possible to eliminate a user's disadvantageous state that a state in which a specific function cannot be used continues.
- FIG. 13 is a flowchart for explaining processing until HDD access is enabled in the recording list application according to the present embodiment.
- the recording list application execution state (S926) which is the final state of the flowchart of the transition from power-off to power-on in FIG.
- FIG. 14 shows an image display example of the recorded program list 1400 displayed with the warning panel 1401 superimposed. In FIG. 14, a message “HDD is starting up. Please wait for a while” is displayed on the warning panel 1401.
- the HDD 203 transmits a notification indicating that the spin-up process has been completed to the LSI 202.
- the LSI 202 detects that access to the HDD 203 is possible (S1303).
- the LSI 202 deletes the display on the warning panel 1401 (S1304), and starts playing the selected recorded program (S1305).
- the video data of the recorded program is stored on the HDD 203, and the video data to be reproduced can be identified by referring to the file path information to the video data in the recorded program information table 600.
- the warning panel 1101 (FIG. 11) is deleted, and the warning panel 1101 is deleted after 3 seconds. .
- the play button 404 is pressed, the warning panel 1101 is not deleted.
- the editing operation usually requires various operations, and the user is trying to start the operation with such awareness. Therefore, it can be considered that there is relatively little resistance to pressing the submenu button 403 again to perform the operation again.
- the replay operation only requires pressing the “replay button” 404 for the designated recorded program, and the operation to be performed is clear. Since the user does not intend to perform the operation many times, it is preferable to reduce the number of operations as much as possible. In view of such circumstances, the operational differences described above are provided.
- the recorder 101 temporarily stores in memory a minimum amount of data required when the recording list application displays the recording list. Thereby, the recorder 101 can display a recording list at high speed from the power-off state. More specifically, the recording list can be displayed at a higher speed (for example, within one second) than the configuration in which data is stored in the flash memory and read into the buffer memory after power-on as in Patent Document 1. .
- the user can immediately check the recording list, and can immediately find a desired program. Further, when the user presses the reproduction key to reproduce a desired program, a message is displayed until the HDD 203 becomes accessible, and the process automatically shifts to reproduction processing when the HDD becomes accessible. This eliminates a user's useless remote control operation such as pressing the reproduction key many times.
