It records (records, records) television broadcasting, audio, and the like as a recording medium.
[0033]
Next, FIG. 2 shows a circuit configuration of the portable television recorder 1.
[0034]
In the figure, an RF signal of a television broadcast received by a helical antenna 12 is supplied to a tuner 21.
[0035]
The tuner 21 selects a channel (frequency) designated by the control unit 22 and converts it into an intermediate frequency signal, which is separated into a video intermediate frequency signal and an audio intermediate frequency signal by filtering. The signal is output to the video amplification circuit 23, and the audio intermediate frequency signal is output to the audio detection circuit 24.
[0036]
The video amplifying circuit 23 amplifies the transmitted video intermediate frequency signal and then performs video detection to generate a video signal, and further separates a horizontal synchronization signal H-SYNC and a vertical synchronization signal V-SYNC included in the video signal, The video signal is subjected to chroma processing to obtain a chroma signal composed of three primary colors of R, G, and B. The separated horizontal synchronizing signal H-SYNC, vertical synchronizing signal V-SYNC, and the chroma signal are supplied to the video output circuit 25. Output.
[0037]
The video output circuit 25 controls and drives the display section 3 formed of a color TFT liquid crystal display panel based on the horizontal synchronization signal H-SYNC and the vertical synchronization signal V-SYNC and the chroma signal, and displays a television image.
[0038]
On the other hand, the audio detection circuit 24 performs audio detection and FM demodulation on the audio intermediate frequency signal from the tuner 21 to generate an audio signal in the audible frequency range, and sends it to the audio amplification circuit 26.
[0039]
The audio amplifying circuit 26 amplifies the audio signal from the audio detection circuit 24 with an amplification factor specified by the control unit 22 and drives the speaker unit 5 with the obtained signal to emit television sound. Or from the stereo jack 15.
[0040]
The control unit 22 operates as a work memory, a ROM storing a CPU and its operation program, and a RAM holding a recording reservation information, which will be described later, and the like. The operation of the entire portable television recorder 1 is controlled, and the timekeeping unit 28, the memory card 17, the MPEG circuit 29, the indicator unit 9, and the power controller 30 are also connected.
[0041]
The key input unit 27 has the video key 4, the ring key 6, the enter key 7, the function keys 8, the power key 10, and the "bookmark" key 11, and directly inputs an operation signal accompanying the key operation to the control unit. Input to 22.
[0042]
The timer 28 measures the current time irrespective of whether the power of the portable television recorder 1 is turned on or off, and the time information is read out to the controller 22.
[0043]
The MPEG circuit 29 compresses a video signal at the time of recording at a resolution of 720 × 480 dots and a frame rate of 30 frames / second in the standard mode and records the video signal on the memory card 17 in accordance with the MPEG4 standard, for example. Expands the compressed video signal read from the
[0044]
The power supply controller 30 supplies power using the DC voltage to each circuit in the portable television recorder 1 while a DC voltage from an AC adapter (not shown) is applied to the DC jack 16 while the DC jack 16 When no DC voltage is applied from an AC adapter (not shown), the portable TV recorder 1 supplies power generated by a battery power supply built therein.
[0045]
Next, the operation of the above embodiment will be described.
[0046]
FIGS. 3 and 4 show the contents of processing executed when the “recording reservation” key of the function keys 8 is operated, and is mainly based on the operation program stored in the ROM by the control unit 22. Execute operation control.
[0047]
At the beginning of the process, first, the recording reservation pattern, specifically, whether to record “once” in the time zone and channel to be set, to record “every day”, or to record in the same day of the week thereafter The user operates the ring key 6 and the enter key 7 in accordance with the guide message displayed on the display unit 3 to determine whether or not to perform the operation (step S01).
[0048]
Thereafter, a start time, an end time, and a channel of the recording are designated (steps S02 to S04), and finally, for example, one of the modes "fine", "standard", and "economy" is selected depending on the difference in image quality and sound quality (step S02). S05).
[0049]
The approximate required recording capacity can be roughly estimated from the selected mode and the input time range. The control unit 22 checks the free capacity of the memory card 17 (step S06), and sets the recording capacity. It is determined whether or not the memory card 17 has a free space for recording all the reserved contents (step S07).
[0050]
Here, there is no problem when the free space is sufficient, but when it is considered that the free space is insufficient, the display unit 3 displays, for example,
"Not enough memory
Replace the memory or change the entry. "
While prompting for a response (Step S08), it is repeatedly determined whether or not the memory card 17 has been actually replaced (Step S09) and whether or not re-input has been designated (Step S10). To wait for any of these actions to be taken.
[0051]
If the memory card 17 has been replaced, this is determined in step S09, and the process proceeds to step S06 to check the free space of the newly replaced memory card 17.
[0052]
If a re-input has been specified, this is determined in step S10, and the process is repeated from step S01.
[0053]
If it is determined in step S07 that there is enough free space in the memory card 17 to record all of the reservation contents set in step S07, it is determined that one recording reservation has been completed, and whether or not the reservation is to be ended is determined. In other words, the user is urged to perform an operation to select whether or not to make another recording reservation, and a determination is made based on the operation result (step S11).
[0054]
Here, if the operation for continuing the other recording reservation is performed without terminating the reservation, the process returns to the process from step S01 again, and another recording is performed within the free space of the memory card 17. Continue the processing related to the reservation.
[0055]
Then, when an operation for ending the reservation is performed after executing all the recording reservations that can be recorded on the free space of the memory card 17, this is determined in step S11, and all the input information that has been reserved for recording is determined by the control unit. After the data is collectively stored and set in the storage 22 (step S12), it is determined from the signal from the power supply controller 30 whether or not the DC voltage from the AC adapter is applied to the DC jack 16 at that time (step S13). .
[0056]
Here, if it is determined that the DC voltage from the AC adapter is not applied to the DC jack 16, even if the state shifts to the reserved recording state as it is, the reserved recording operation can be executed to the end only with the battery power. While it is unlikely that a DC voltage is actually applied from the AC adapter to the DC jack 16 while the warning message prompting the connection of the AC adapter is displayed on the display unit 3 (step S14), it is determined (step S14). By repeatedly executing the processing of S15), the apparatus waits for power to be supplied from the AC adapter.
[0057]
FIG. 5 shows an example of a warning message displayed on the display unit 3 at this time. Here, a message with a large exclamation mark "!"
"AC Adapter
Please connect"
Is displayed, a warning is issued to a user who has made a recording reservation of the portable television recorder 1.
[0058]
When it is determined in step S15 that the DC voltage from the AC adapter has been applied to the DC jack 16, or in step S13 above, it has been determined that the DC voltage from the AC adapter has been applied to the DC jack 16 from the beginning. In order to re-enter the recording reservation state, a message prompting the user to perform a necessary operation, for example, the operation of the enter key 7 or the power key 10 is displayed (step S16), and the operation of the key is actually performed. It waits (step S17).
[0059]
If it is determined in step S17 that a necessary key operation has been performed, the process shifts to a standby state for reserved recording (step S18). Thereafter, it is determined whether a DC voltage from an AC adapter is applied to the DC jack 16 (step S18). S19) While repeatedly determining whether or not the current time measured by the timer 28 has reached the reserved recording start time (step S20), the process waits for the reserved recording start time.
[0060]
In the standby state of the scheduled recording, the DC jack includes a case where the AC adapter connected to the DC jack 16 is disconnected due to an accident or the like, or a case where the outlet of the AC adapter is disconnected. If the DC voltage applied to the DC jack 16 has stopped, it is determined in the above step S19, and then it is determined whether or not it is necessary to apply the DC voltage to the DC jack 16 at that time (step S19). S21).
[0061]
This prevents a warning message from being displayed every time the AC adapter is disconnected in the portable TV recorder 1 that is presumed to be used for portable use, for example, when a scheduled recording is reserved for daily or weekly recording. It is determined whether or not the recording pattern selected in step S01 is reserved for one-time recording instead of daily or weekly, and whether the recording pattern for the daily or weekly recording pattern is reserved. It is determined whether or not the first scheduled recording has been performed yet.
[0062]
However, if it is determined in step S21 that the DC voltage needs to be applied to the DC jack 16, even if the recording has been performed at the reserved start time, the reserved recording operation is performed to the end using only the battery power. It is determined that the DC voltage is not actually applied to the DC jack 16 while displaying a warning message prompting the connection of the AC adapter on the display unit 3 (step S22). (Step S23), the process waits for power to be supplied from the AC adapter.
[0063]
FIG. 6 exemplifies a warning message displayed on the display unit 3 at this time. Here, a message with a large exclamation mark "!"
"AC adapter
It has come off
Please reconnect. "
Is displayed, a warning is issued to a user who has made a recording reservation of the portable television recorder 1.
[0064]
If it is determined in step S23 that DC voltage from the AC adapter has been applied to the DC jack 16 or if it is determined in step S21 that application of DC voltage to the DC jack 16 is not necessary, Then, the process proceeds to step S20, and returns to the standby state of the reserved recording until the reserved start time comes again.
[0065]
Thereafter, when this is determined at step S20 at the time when the reserved start time has been reached, while the recording process in the selected recording mode and channel is being executed (step S24), the current time is changed to the reserved time. The scheduled recording process is continued by repeatedly executing the process of determining whether or not the recording end time has come (step S25).
[0066]
Then, when it is determined in step S25 that the end time has come, the timer recording process is stopped, and it is determined that one timer recording has been completed, and then it is determined whether there is another timer recording content ( Step S26).
[0067]
Here, if it is determined that there is still another content of the reserved recording, the process returns to the process from step S19 again, and shifts to the standby state for the next reserved recording.
[0068]
On the other hand, if it is determined in step S26 that there is no other scheduled recording, it is determined that all the processing related to the scheduled recording has been completed, and the power is completely turned off to avoid further unnecessary power consumption.
[0069]
As described above, when the DC voltage is not applied from the AC adapter to the DC jack 16 at the time of setting the reservation recording input, the display unit 3 warns the user and notifies the user as shown in FIG. The AC adapter was connected correctly.
[0070]
As a result, a stable power supply state from the AC adapter and no need to worry about the power supply capacity is ensured, and a transition is made to the standby state for scheduled recording, so that the power supply state is unstable due to the built-in battery. It is possible to reliably avoid a transition to a standby state for scheduled recording.
[0071]
In addition, if the connection with the AC adapter is interrupted and the DC voltage is no longer supplied to the DC jack 16 even after the recording reservation is once in the standby state, the display unit 3 displays the DC voltage as shown in FIG. The user was warned and notified, and the AC adapter was correctly connected again.
[0072]
As a result, a stable power supply state from the AC adapter, which does not need to worry about the power supply capacity, is obtained, and then the standby state for the scheduled recording is restored. Therefore, the AC adapter is connected to the DC jack 16 in the standby state. Even if the connection has been disconnected for some reason, by alerting the user of this, it is possible to avoid continuing the standby state of the scheduled recording with the connection disconnected.
[0073]
At the time of displaying the message in step S22 shown in FIG. 6 as well, an alarm sound or the like may be output from the speaker unit 5 only for a fixed time or intermittently in a fixed time cycle.
[0074]
Although the above embodiment describes the case where the present invention is applied to the portable television recorder 1, the present invention is not limited to this, and may be applied to, for example, a notebook type personal computer equipped with a television tuner. It can be easily applied.
[0075]
Even without a TV tuner, the present invention can be applied to a streaming broadcast that connects to the Internet instead of receiving a TV broadcast and records image data distributed on the Internet.
[0076]
In addition, it goes without saying that the present invention can be similarly applied to a portable television recorder or a notebook type personal computer having a tuner capable of receiving digital broadcasting even if the television broadcasting becomes digital broadcasting in the future.
[0077]
In addition, the present invention is not limited to the above-described embodiment, and can be variously modified and implemented without departing from the gist thereof.
[0078]
