<First Embodiment>
A first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration of a video recording / playback apparatus according to the present embodiment. FIG. 2 is a block diagram showing an internal configuration of the recording apparatus in the video recording / reproducing apparatus of FIG. FIG. 3 is a block diagram showing the internal configuration of the playback apparatus in the video recording / playback apparatus of FIG.

  The video recording / reproducing apparatus of FIG. 1 reproduces the content recorded on the recording apparatus 1 while being separable from the recording apparatus 1 which is a main body part for recording the content obtained by receiving the broadcast signal and the recording apparatus 1. And a playback device 2 for displaying. At this time, the reproducing apparatus 2 has portability by providing a heavy dischargeable power source (not shown) such as a secondary battery, and the reproducing apparatus 2 is connected to the recording apparatus 1 so that this power source is connected. Is charged.

  As shown in FIG. 2, a recording apparatus 1 that is a main part of the video recording / reproducing apparatus includes an antenna 11 that receives a broadcast signal, a tuner 12 that selects a broadcast signal received by the antenna 11, and a tuner 12. An encoder 13 that encodes a received broadcast signal using a compression encoding method such as the MPEG method, and data obtained by encoding the broadcast signal by the encoder 13 (hereinafter referred to as “content data”). A recording medium 14 such as a hard disk, a memory 15 having a content reference table storing information related to recording reservation or recorded content, and a program for performing various operations, and a timer 16 for measuring time A CPU (Central Processing Unit) 17 that performs the operation of the entire apparatus by a program in the memory 15 and the playback apparatus 2 are placed. Comprises an interface (I / F) 18 that communicates with the reproducing apparatus 2 is connected with Rukoto, a bus 19 for transmitting signals between each block.

  Further, as shown in FIG. 3, the reproducing apparatus 2 that is connected to the recording apparatus 1 by being mounted on the recording apparatus 1 includes an I / F 21 that is connected to the I / F 18 of the recording apparatus 1 and the reproducing apparatus 2. A recording reservation table in which received content data is recorded and recording reservation information is stored, a memory 22 having a program for performing various operations, content data read from the memory 22 is decoded, and a video signal and A decoder 23 for converting into an audio signal, a display unit 24a for displaying video by reproducing the video signal obtained by the decoder 23, and a speaker 24b for outputting audio by reproducing the audio signal obtained by the decoder 23 And an operation unit 25 in which an input operation is performed by the user, a CPU 26 that operates the entire apparatus by a program in the memory 22, and an alarm display. It provided with ED (Light Emitting Diode) 27, a bus 28 for transmitting signals between each block.

  When the video recording / reproducing apparatus is configured in this way, the recording apparatus 1 receives the broadcast signal selected by the tuner 12 via the antenna 11. At this time, when receiving an analog broadcast, the tuner 12 performs a channel selection operation at a channel frequency designated by the CPU 17, and then demodulates and decodes the broadcast signal, and broadcasts using the obtained video signal and audio signal. The signal is sent to the encoder 13. When receiving a digital broadcast, the tuner 12 sends a broadcast signal obtained by demodulation after performing a channel selection operation at the channel frequency designated by the CPU 17 to the encoder 13.

  When the broadcast signal obtained by the tuner 12 is given to the encoder 13, it is converted into compression-encoded content data and recorded on the recording medium 14 via the bus 19. At this time, when an analog broadcast is received by the tuner 12, content data is generated by digitally encoding a video signal and an audio signal, which are analog signals given from the tuner 12, and then compressing and encoding. When a digital broadcast is received by the tuner 12, the broadcast signal supplied from the tuner 12 is converted into a digital signal, whereby content data that has been compression-encoded can be obtained. If the compression encoding method used in digital broadcasting is different from the compression encoding method used when storing in the recording medium 14, the content data recognition of the compression encoding method used when storing in the recording medium 14 in the encoder 13 is performed. Convert.

  As shown in FIG. 4, the content reference table provided in the memory 15 has an address position (start address position), a broadcast channel, a recording start time, a recording end time, Each recording time and memory usage is stored as recording information. In the content reference table, the start address position recorded on the recording medium 14 and the memory usage used for recording are stored for the content data recorded on the recording medium 14. On the other hand, since the content data that is scheduled for recording is not recorded on the recording medium 14, “NULL” indicating that the recording is not performed is stored in the column (address location column) in which the start address position is stored. The memory usage amount column (memory usage amount column) stores the memory usage amount predicted to be necessary for recording.

  The CPU 17 refers to the content reference table stored in the memory 15 to confirm the recording start time of the content data that has not been recorded and reserved for recording. Then, in contrast to the current time measured by the timer 16, the content data that is the recording start time that matches the current time is confirmed. When the content data having the recording start time that matches the current time is confirmed, the channel frequency is set so that the tuner 12 confirms the broadcast channel from the content reference table and the tuner 12 selects the broadcast signal of the broadcast channel. The

  When the recording operation starts, content data is stored in the recording medium 14 by operating the tuner 12, the encoder 13, and the recording medium 14 as described above. At this time, the address where the first data of the content data given to the recording medium 14 is stored is stored in the address position column of the content reference table in the memory 15 as the start address position. Thereafter, when the CPU 17 confirms that the current time from the timer 16 has reached the recording end time, the recording operation to the recording medium 14 is stopped, the recording is ended, and the memory used for the recorded content data Check capacity. This confirmed memory capacity is stored in the memory usage column of the content reference table in the memory 15.

  That is, when it is confirmed by the timer 16 that it is 15:00:00 on March 25, 2004, the recording start time of the unrecorded content C8 is obtained from the content reference table in FIG. Make sure that there is. Then, the channel frequency in the tuner 12 is set to the channel frequency of the broadcast channel Ch3, and the recording operation of the content data obtained by the encoder 13 onto the recording medium 14 is started. At this time, if it is confirmed that the recording is started from the address position Az of the recording medium 14, the start address position Az is stored in the address position column of the content reference table as shown in FIG. When it is confirmed by the timer 16 that 15:58:00 on March 25, 2004, it is confirmed that it is the recording end time of the content C8, the recording operation is ended. At this time, it is confirmed that the memory capacity is 198 Mbytes, and the memory capacity 198 Mbytes is stored in the memory usage column of the content reference table as shown in FIG.

  The playback device 2 also stores in the memory 22 a content data table as shown in FIG. 6 showing a list of a plurality of content data, and recording reservation information in which recording start time, recording end time, and broadcast channel are set. The recording reservation table as shown in FIG. 7 is stored. The content data table of FIG. 6 records the broadcast channel, recording start time, recording end time, recording time, and start address position in the memory 22 of each content data stored in the memory 22, and FIG. The recording reservation table stores a broadcast channel, a recording start time, a recording end time, a recording time, and a memory usage amount of the content reserved for recording.

  When the operation unit 25 is operated to instruct the reproduction of content, the instruction content is confirmed by the CPU 26 and the content data table stored in the memory 22 is confirmed. When the broadcast channel, the recording start time, the recording end time, and the recording time of each content data confirmed in the content data table are read out, they are given to the decoder 23, converted into a video signal, and given to the display unit 24a. The display unit 24a displays the broadcast channel, recording start time, recording end time, and recording time of each content stored in the memory 22.

  For the reproducible content displayed on the display unit 24a, a pointer indicating the selected content is displayed by inverting the color at the designated position. By moving the pointer by operating the operation unit 25 by the user, the pointer is moved to the content desired to be reproduced. When the content desired to be reproduced is selected by the pointer and the operation unit 25 is operated to instruct to determine the selection, the start address position of the content data for the selected content is determined by the CPU 26. It is confirmed.

  When the start address position of the content data for the content selected in this way is confirmed, the content data stored in the memory 22 is read in order from this start address position. The content data read from the memory 22 is decompressed by the decoder 23 to generate a video signal and an audio signal. The video signal is supplied to the display device 24a and the audio signal is supplied to the speaker 24b. Then, the video and audio of the content desired by the user are reproduced and output. Thereafter, when all the content data related to the content is read from the memory 22 and reproduced and output, the reproduction operation ends.

  When the playback apparatus 2 is installed in the recording apparatus 1, the user operates the operation unit 25 of the playback apparatus 2 to change the selected broadcast channel in the recording apparatus 1 so that the desired broadcast channel is set. The content can be reproduced and output by the display unit 24a and the speaker 24b. That is, when a broadcast channel to be received is selected by the operation unit 25, it is given to the recording apparatus 1 through the I / F 21 and the I / F 18. In the recording apparatus 1, the selected broadcast channel is confirmed by the CPU 17, and the channel frequency in the tuner 12 is switched.

  By doing so, in the recording apparatus 1, a broadcast signal of a desired broadcast channel is received by the tuner 12. Then, when the received broadcast signal is converted into content data by the encoder 13, it is given to the playback device 2 through the I / F 18 and the I / F 21. Therefore, in the playback device 2, the content data of the desired broadcast channel is reproduced and output by the display unit 24a and the speaker 24b by decoding the content data by the decoder 23.

  A recording reservation operation by the video recording / reproducing apparatus including the recording apparatus 1 and the reproducing apparatus 2 will be described below with reference to the drawings. FIG. 8 is a flowchart showing the operation of the playback apparatus 2 during the recording reservation operation. FIG. 9 is a flowchart showing the operation of the playback apparatus 2 during data transfer. FIG. 10 is a flowchart showing the operation of the recording apparatus 1 during data transfer.

  First, the operation of the playback device 2 will be described. When the operation unit 25 is operated by the user and the recording start time and the recording end time and the broadcast channel for the content to be reserved for recording are input (STEP 1), is the I / F 18 of the recording apparatus 1 connected by the I / F 21? It is confirmed whether or not (STEP 2). In STEP 1, when a recording reservation is instructed by the operation unit 25, a setting screen for recording reservation is displayed on the display unit 24a. When the operation unit 25 is operated, the recording start time, the recording end time, and the broadcast channel are displayed on the display unit 25. After displaying the recording start time, the recording end time, and the broadcast channel, the user operates the operation unit 25 to determine the input, thereby completing the input.

  When the connection with the recording apparatus 1 is confirmed in STEP 2 (Yes), the input recording reservation information is given to the I / F 21 through the bus 28, and then the recording reservation information is transferred to the recording apparatus 1 (STEP 3). The reservation operation is finished. If it is confirmed that the recording device 1 is not connected (No), the inputted recording reservation information is stored in the recording reservation table in the memory 22 through the bus 28 (STEP 4). Then, the CPU 26 confirms whether or not the LED 27 is blinking (STEP 5). At this time, if another recording reservation information exists in the recording reservation table in the memory 22 and the LED 27 is blinking (Yes), the reservation operation is terminated. If the LED 27 is not blinking (No), the LED 27 starts blinking (STEP 6), and the reservation operation is terminated.

  Therefore, the recording reservation operation is performed when the playback apparatus 2 is not connected to the recording apparatus 1, whereby the operation of STEP 4 in the flowchart of FIG. 8 is performed, and the recording reservation information is stored in the recording reservation table in the memory 22. Stored. When the reproducing apparatus 2 storing the recording reservation information is placed on the recording apparatus 1 and the I / F 21 of the reproducing apparatus 2 is connected to the I / F 18 of the recording apparatus 1, the flowchart of FIG.

It is confirmed whether or not (STEP 102). At this time, if it is confirmed that the recording reservation information is stored (Yes), the recording reservation information stored in the recording reservation table in the memory 22 is read out and is recorded from the interface 21 through the bus 28 through the interface 21. 1 (STEP 103). Then, the blinking of the LED 27 is turned off (STEP 104).

  When the blinking of the LED 27 is turned off in STEP 104 or when the recording reservation information is not confirmed in STEP 102 (No), the operation unit 25 is operated to store the content memory 22 stored in the recording medium 14 of the recording apparatus 1. It is confirmed whether or not storage in the file is requested (STEP 105). At this time, if the storage of the content in the memory 22 is instructed (Yes), a recording information request signal for requesting recording information related to the content stored in the recording medium 14 of the recording device 1 is transmitted (STEP 106). Recording information from the recording apparatus 1 is received via / F21 (STEP 107).

  Then, the received recording information is given to the decoder 23 via the bus 28, so that the decoder 23 decodes the recording information and the recording start time and the recording end based on the recording information regarding the content stored in the recording medium 14 of the recording device 1. The time and the broadcast channel are displayed on the display unit 24a (STEP 108). Thus, when the recording information of the content stored in the recording medium 14 of the recording device 1 is displayed on the display unit 24a, the content stored in the memory 22 is selected by operating the operation unit 25 (STEP 109).

  When the operations of STEP 108 and STEP 109 are performed, the content stored in the memory 22 is confirmed from the content data table, and the recording information regarding the content not stored in the memory 22 is given from the recording device 1. At this time, whether or not it has already been stored in the memory 22 may be confirmed by the recording apparatus 1 from the content reference table in the memory 15. In STEP 109, the recording information displayed on the display unit 24a is selected by the pointer, and a plurality of contents can be further selected. Further, when the selection operation of STEP 109 is being performed, the selection of content may not be performed. Then, when the operation unit 25 instructs to end the selection operation, the process proceeds to STEP 110.

  When the selection operation in STEP 109 is performed, it is confirmed whether or not content has been selected (STEP 110). At this time, if it is confirmed that the content is selected (Yes), the CPU 26 generates a data transmission request signal for requesting transmission of the content data of the selected content, and the recording device 1 from the I / F 21. (STEP 111). Thereafter, the content data transmitted from the recording device 1 is received by the I / F 21 (STEP 112). Then, the content data received by the I / F 21 is recorded in the memory 22 via the bus 28 (STEP 113), and the operation ends. At this time, the recording information of the content related to the recorded content data is stored in the content data table in the memory 22. It should be noted that when the free space in the memory 22 is small, the content data of the already viewed content stored in the memory 22 may be automatically deleted.

  Further, when the storage of the content in the memory 22 is not instructed in STEP 105 (No), or when the content is not selected in STEP 110 (No), the operation is terminated. As described above, when the playback device 2 is placed on the recording device 1 to transmit recording reservation information to the recording device 1 and to receive content data from the recording device 1, the playback device 2 receives the recording device 1. It does not matter if it is charged through

  When the warning time is updated in STEP 11 or when the input recording start time is later than the warning time in STEP 10 (No), the LED 27 blinks as in the first embodiment. Is confirmed, and when the LED 27 is not blinking, the LED 27 starts blinking (STEP 5 and STEP 6).

  As described above, the playback device 2a in which the recording reservation operation is performed performs the following warning switching operation according to the flowchart of FIG. First, it is confirmed whether or not recording reservation information is stored in the recording reservation table in the memory 22, and whether or not there is a warning time is confirmed (STEP 301). At this time, when the warning time is not stored in the memory 22 (No), the operation is terminated. If the warning time is stored in the memory 22 (Yes), the stored warning time is read from the memory 22 (STEP 302).

  Then, the remaining time obtained by subtracting the warning time from the current time confirmed by the timer 29 is confirmed, and it is confirmed whether or not the remaining time is equal to or less than a predetermined threshold (time T1) (STEP 303). At this time, if it is confirmed that the remaining time is within the time T1 (Yes), it is then confirmed whether or not the remaining time is 0 or less (STEP 304). Furthermore, when it is confirmed that the remaining time is 0 or less (Yes), in order to warn that it is impossible to record the content reserved for recording with the warning time as the recording start time, as shown in FIG. Recording reservation information with the warning time as the recording start time is displayed on the display unit 24a (STEP 305). At this time, in order to allow the user to determine whether or not to change the recording start time in the recording information, as shown in FIG. 14, the display "24 Change start time?" Is displayed on the display unit 24a together with the recording reservation information.

  Then, it is confirmed whether or not the operation unit 25 is operated to input the change of the recording start time (STEP 306). At this time, if it is confirmed that the recording start time is changed (Yes), the recording start time in the recording reservation information displayed in STEP 305 is changed to the recording start time newly input by the operation unit 25. And stored in the recording reservation table in the memory 22 (STEP 307). If the recording reservation information is instructed to be deleted without changing the recording start time (No), the recording reservation information displayed in STEP 305 is deleted from the recording reservation table in the memory 22 (STEP 308).

  When the operation for changing the recording start time in STEP 307 and the operation for deleting the recording reservation information in STEP 308 are performed, the contents of the recording reservation table in the memory 22 are confirmed and the recording start time that is the earliest time is recognized and a new warning is issued. After the time is updated (STEP 309), the process proceeds to STEP 301. In STEP 303, if the remaining time is longer than the threshold time T1 (No), the process proceeds to STEP 301.

  Further, in STEP 304, when the remaining time is longer than 0, the blinking speed of the LED 27 is switched to be faster (STEP 309). Then, as shown in FIG. 15, the remaining time is displayed together with the current time on a part of the display unit 24a to inform the user of the remaining time (STEP 310). After performing the display operation for the remaining time, the process proceeds to STEP301. In STEP 309, the speed may be switched so that the blinking speed of the LED 27 becomes faster as the remaining time becomes shorter. In addition, when the blinking speed of the LED 27 is increased, the LED 27 may be finally turned on to give attention to the user.

<Third Embodiment>
A third embodiment of the present invention will be described with reference to the drawings. The video recording / reproducing apparatus of this embodiment is configured as shown in FIG. 1 as in the first embodiment, and the internal configuration of the recording apparatus is as shown in FIG. 2 as in the first embodiment. Configured. The internal configuration of the recording apparatus is also configured as shown in FIG. 11 as in the second embodiment.

  In the video recording / reproducing apparatus of this embodiment, the free capacity of the recording medium 14 of the recording apparatus 1 is confirmed in each of the recording apparatus 1 and the reproducing apparatus 2a. Further, in the playback device 2a, it is determined whether or not recording reservation is possible according to the confirmed free space. Then, when the recording reservation operation is performed in the playback device 2a, the operation is the same as in the first or second embodiment except that the recording reservation availability determination operation is performed.

  In such a video recording / playback apparatus, the recording apparatus 1 checks the memory usage field in the content reference table in the memory 15. And the total memory capacity of the used memory capacity used by the content stored in the recording medium 14, and the total memory capacity of the used memory capacity (referred to as the predicted memory capacity) predicted for the content reserved for recording. Is confirmed. By subtracting the total memory capacity of the used memory capacity and the predicted memory capacity from the total memory capacity of the recording medium 14, the free memory capacity (free capacity) of the recording medium 14 is confirmed and stored in the memory 15.

  When the free memory capacity of the recording medium 14 is confirmed, the free memory capacity of the recording medium 14 is confirmed by subtracting the total memory capacity of the predicted memory capacity from the actual free memory capacity of the recording medium 14. It doesn't matter. Further, the free memory capacity of the recording medium 14 stored in the memory 15 may be stored when the content is recorded and the content data is stored in the recording device 1, and may be stored periodically. 14 free memory capacities may be confirmed and stored.

  The free memory capacity thus confirmed and stored in the memory 15 is transferred from the recording device 1 to the reproducing device 2a when the reproducing device 2a is connected to the recording device 1. That is, as shown in the flowchart of FIG. 16, when the recording apparatus 1 confirms that the I / F 18 is connected to the I / F 21 of the reproducing apparatus 2 a in STEP 201, the free memory capacity of the recording medium 14 stored in the memory 15 is reduced. The data is transferred from the I / F 18 to the playback device 2a (STEP 251), and the process proceeds to STEP 202. Thereafter, the same operation as the flowchart of FIG. 10 is performed.

  At this time, as shown in the flowchart of FIG. 17, when the reproducing apparatus 2 a confirms that the I / F 21 is connected to the I / F 18 of the recording apparatus 1 in STEP 101, the recording medium 14 transmitted from the recording apparatus 1. Is received by the I / F 21 (STEP 151). Then, the received free memory capacity of the recording medium 14 is stored in the memory 22 (STEP 152), and the process proceeds to STEP 102. Thereafter, the same operation as the flowchart of FIG. 10 is performed.

  Further, the reproducing device 2a storing the free memory capacity of the recording medium 14 of the recording device 1 in the memory 22 in this way performs a recording reservation operation according to the flowchart of FIG. That is, when the recording reservation information is input by the user in STEP 1, the recording time is confirmed by the input recording start time and recording end time, and the memory capacity to be used is predicted (STEP 401). Then, it is confirmed whether or not the predicted memory capacity is larger than the free memory capacity of the recording medium 14 stored in the memory 22 (STEP 402).

  At this time, if the predicted memory capacity is larger than the free memory capacity of the recording medium 14 (Yes), it is displayed on the display unit 24a that the recording reserved content cannot be recorded (STEP 403), and the operation is terminated. If the predicted memory capacity is smaller than the free memory capacity of the recording medium 14 (No), the process proceeds to STEP2. Thereafter, the same operation as the flowchart of FIG. 12 is performed. By operating in this way, it is possible to indicate that recording is impossible when a recording reservation is made for a content that is predicted to have a memory capacity larger than the free memory capacity of the recording medium 14.

  In this embodiment, when recording reservation information is input in STEP 1, the free memory capacity that can be recorded by the user so that the free memory capacity of the recording medium 14 stored in the memory 22 is displayed on the display unit 24 a. You may be able to confirm. At this time, the recordable time may be calculated from the free memory capacity of the recording medium 14 stored in the memory 22 and displayed on the display unit 24a.

  Furthermore, in STEP 403, after displaying that the content reserved for recording cannot be recorded, the operation shown in the flowchart of FIG. 19 may be performed. That is, the recording reservation information stored in the recording reservation table in the memory 22 is read (STEP 501) and displayed on the display unit 24a together with the recording reservation information input in STEP 1 (STEP 502). Is selected (STEP 503). At this time, it is confirmed whether or not the recording reservation information in the recording reservation table is deleted (STEP 504).

  When the recording reservation information in the recording reservation table is selected as information to be deleted (Yes), first, the selected recording reservation information is deleted from the recording reservation table in the memory 22 (STEP 505). The used memory capacity of the deleted recording reservation information is added to the free memory capacity of the recording medium 14 stored in the memory 22 and newly updated as the free memory capacity of the recording medium 14 (STEP 506). Then, after confirming the recording reservation table after deletion, the recording start time that is the earliest time is recognized, the recording start time that is the earliest time is updated as a warning time (STEP 507), and then the process proceeds to STEP 402. Thus, the updated free memory capacity is compared with the predicted memory capacity. In STEP 504, when the input recording reservation information is selected as information to be deleted (No), the input recording reservation information is deleted (SETP508), and the operation is terminated.

  As described above, in the case of performing the operation as shown in the flowchart of FIG. 19, when the playback device 2a is connected to the recording device 1, and the predicted memory capacity of the content to be reserved for recording is larger than the free memory capacity, The recording reservation information in the content reference table in the memory 15 of the recording device 1 may be confirmed. At this time, if the predicted memory capacity of the content to be reserved for recording is larger than the free memory capacity, the input recording reservation information or the recording reservation information in the content reference table in the memory 15 is selected and deleted.

  In the first to third embodiments, when the recording apparatus 1 records EPG (Electric Program Guide) in the recording medium 14 or the memory 15 and is connected to the recording apparatus 1 with respect to the reproducing apparatuses 2 and 2a. The contents of the EPG after the current time may be transferred. At this time, the playback devices 2 and 2a store the EPG in the memory 22 and read the EPG when recording reservation information is input, thereby confirming the content name and the memory usage capacity. Therefore, a more accurate memory usage capacity can be predicted for the content reserved for recording, and a content name such as a program name can be stored in each table. Further, the recording apparatus 1 receives a broadcast signal from an antenna. However, the recording apparatus 1 may be connected to a cable, an optical fiber, a DSL (Digital Subscriber Line) line, or the like, and may be received from the wired connection line. .
