Description

  The present invention relates to a television receiver with a built-in memory card recording function.

  Recently, there is an increasing expectation to watch television programs in mobile usage environments such as commuting hours, and television receivers capable of recording television programs on a memory card are on the market. The capacity of memory cards as recording media is also increasing. However, the recording capacity of the memory card is smaller than that of a hard disk, a DVD disk or the like, and there is a restriction such as dropping the image quality mode in order to record a program for a long time on one memory card. In addition, in a conventional television receiver with a built-in memory card recording function, when recording a program longer than the recordable time, the recording stops when the remaining memory capacity is exhausted as disclosed in Patent Document 1. In order to perform continuous recording, the recording must be reset, which increases the burden on the user.

In addition, when the recordable time runs out, as a means for continuing the recording, the first and second recording / reproducing devices are connected as disclosed in Patent Document 2, and the first recording is performed. There is a method of continuously outputting to the second recording / reproducing apparatus when the recordable time of the recording medium in the reproducing apparatus is exhausted. However, this method has a drawback that continuous output cannot be performed as it is due to insertion and removal of the memory card.

(Embodiment 1)
Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 5. FIG. 1 is a block diagram of a television receiver as an example of the embodiment of the present invention. The analog tuner 1 converts analog terrestrial broadcast waves and the digital tuner 2 converts satellite digital and terrestrial digital broadcast waves into AV signals, and the converted AV signals are sent to the signal switching unit 3. Further, program information, time information, and audio information obtained from digital broadcasting or analog terrestrial broadcasting are notified to the control unit 8, and the program information is recorded in the program information storage device 11.

  The control unit 8 receives a remote control signal from the remote control transmitter 6 via the remote control light receiving unit 7. The control unit 8 sends information for channel selection to the analog tuner 1 and the digital tuner 2 and sends a switching signal to the signal switching unit 3. The control unit 8 and the memory card control unit 12 communicate bidirectionally, and when the user performs a memory card insertion / extraction operation, the control unit 8 detects the card information inserted into the memory card slot 13 from the memory card control unit 12. Receive. When the user performs a memory card recording or playback operation, the control unit 8 determines whether the operation is possible based on the card information, and transmits a recording / playback command to the memory card. At the time of recording, the control unit 8 transmits to the memory card control unit 12 a time information notification and a recording target selection notification acquired from the terrestrial broadcast or digital broadcast together with the recording command. Further, the control unit 8 determines that the recorded program has transitioned from the main part to the CM due to a change in the audio mode (stereo broadcast, monaural, bilingual) of the audio signal obtained from the analog tuner 1 and the digital tuner 2. The control unit 8 creates on-screen information to be displayed on the display 5 and sends it to the OSD display circuit 9.

  The memory card control unit 12 includes an MPEG encoder and a decoder. When a recording command is received from the control unit 8, the memory card control unit 12 encodes the AV signal input from the signal switching unit 3 and inserts the memory card into the memory card slot 13 or for video storage. Video / audio data is recorded in the memory 14. At this time, the time (time stamp) is written together with the video / audio data recording. During reproduction, the MPEG data from the memory card is decoded and the decoded AV signal is output to the signal switching unit 3. When a memory card is inserted / removed from / to the memory card slot 13, the memory card control unit 12 notifies the control unit 8 of the card insertion / removal. If the remaining capacity of the memory card runs out during recording, the memory card control module stops recording and notifies the control unit 8 that the remaining capacity has run out.

  The LED 10 is turned on by a control signal from the control unit 8. The signal switching unit 3 switches between an analog AV signal, a digital AV signal, and other external inputs based on a switching signal sent from the control unit 8. The video OSD combining unit 4 combines the AV signal output from the signal switching unit 3 and the on-screen signal output from the OSD display circuit 9 and outputs the combined signal to the display 5.

  The video storage memory 14 is a non-volatile memory that temporarily records video signals until the capacity of the memory card is lost during recording and the card is replaced. If a recording device such as an HDD or a DVD is mounted inside, they can be substituted. When a plurality of memory card slots are mounted, a memory card inserted in the second slot may be used.

  FIG. 2 notifies the user that the remaining capacity of the memory card is insufficient with respect to the program time at the time of executing the memory card recording or reservation, and notifies the user that the remaining capacity is insufficient. Shows an example of a message prompting the user to select whether or not to continue recording using the card.

  FIG. 3 shows an example of a message prompting the user to replace the memory card when the remaining card capacity is reduced during recording.

  FIG. 4 shows that when recording a program from the EPG to a memory card or recording a program being viewed, the remaining card capacity is insufficient when the recordable time of the card is insufficient with respect to the broadcast time of the program. This shows the processing procedure until the message is displayed. When a program recording reservation operation (S401) is performed from the EPG, the control unit 8 acquires the broadcast time of the corresponding program from the program information storage device 11 (S402). Further, the control unit 8 obtains the recordable time of the memory card inserted into the memory card slot 13 from the memory card control unit 12 (S403). The control unit 8 compares the acquired broadcast time with the recordable time (S404). If the recordable time is shorter than the recording time, the control unit 8 displays a remaining capacity shortage message (FIG. 2) (S405). When recording on a plurality of cards is selected by the user (YES in S406), a recording continuation setting state is set (S407).

  FIG. 5 shows the flow of recording processing when a television program is recorded on the memory card and the recording continuation setting state is set. During execution of recording on the memory card, the control unit 8 obtains the remaining card recording time from the memory card control unit 12 (S501). When the remaining card recording time becomes shorter than a certain time (S502), the remaining memory card capacity decreases. This is notified to the user by a message (FIG. 3) (S503). When the card replacement is selected by the user (YES in S504), if it is determined that the audio information being recorded has changed and switched to CM (YES in S505), the memory card capacity is lost and a notification of no remaining card capacity is sent to the memory. When notified from the card control unit 12 to the control unit 8 (YES in S506), the control unit 8 stops recording on the memory card and causes the video storage memory 14 to continue recording (S507).

  When the memory card is replaced by the user (YES in S508), the memory card control unit 12 transmits a card insertion / removal notification to the control unit 8 (S509). The control unit 8 acquires the remaining card recording time from the memory card control unit 12 (S510), and if it can be recorded on the memory card (YES in S511), transmits a recording execution command to the memory card control unit 12, Upon receiving the recording start command, the memory card control unit 12 stops recording in the video storage memory 14 and starts recording on the memory card (S512).

  FIG. 6 shows the flow of recording processing when a television program is recorded on the memory card and the display power is turned off in the recording continuation setting state. During the memory card recording execution, the control unit 8 acquires the remaining card recording time from the memory card control unit 12 (S601). If the remaining card recording time is less than a certain time (YES in S602), if it is determined that the audio information being recorded has changed and switched to CM (YES in S603), the memory card capacity is exhausted and a notification of no remaining card capacity is sent to the memory card. When notified from the control unit 12 to the control unit 8 (YES in S604), the control unit 8 stops recording on the memory card and causes the video storage memory 14 to continue recording (S605). Controls the LED 10 to blink the LED (S606).

  When the memory card is replaced by the user (YES in S607), the memory card control unit 12 transmits a card insertion / removal notification to the control unit 8 (S608). The control unit 8 acquires the remaining card recording time from the memory card control unit 12 (S609), and if it can be recorded on the memory card (YES in S610), transmits a recording execution command to the memory card control unit 12, Upon receiving the recording start command, the memory card control unit 12 stops recording in the video storage memory 14 and starts recording on the memory card (S611). The control unit 8 controls the LED 10 and turns off the LED (S612).

  FIG. 7 shows the flow from the end of recording until the video temporarily recorded in the video recording memory is moved to the memory card. After the end of recording (S701), the control unit 8 acquires the remaining card recording time from the memory card control unit 12 (S702), and the remaining card recording time is longer than the recording time recorded in the video storage memory 14 (S703). If YES, the control unit 8 controls the memory card control unit 12 to move the video file to the memory card (S704). The memory card control unit 12 rearranges the recorded video files in time series based on the time stamp of the recorded video file (S705).

  The television receiver of the present invention enables recording to a memory card continuously without replacing the card by installing a plurality of card slots, and even when a video storage memory cannot be secured inside, This can be applied by using a memory card.
