JP 2004-120476 A (Page 6: FIG. 2)

  Here, today, a mobile phone having a function of receiving a television broadcast and a function of recording the received television broadcast is known.

  However, since a mobile phone is carried by a user and used, it may be difficult to obtain a stable reception environment for television broadcast signals. When a television broadcast is recorded in an unstable reception environment, the television broadcast signal received in this unstable reception environment is recorded, so that a television broadcast signal that is difficult to view is recorded. As a result, the storage area of the storage medium is wasted.

  Specifically, when a user moves from point A to point B to point C while recording a desired television broadcast on a mobile phone, the user can successfully receive the television broadcast at point A. It is difficult to receive a television broadcast at the point, and when the user can successfully receive the television broadcast again by moving to the point C, the user is present at the point B where the reception of the television broadcast is difficult. The recorded television broadcast signal is a television broadcast signal that is difficult to view. For this reason, the storage area of the storage medium used for recording the television broadcast signal while the user is at the point B is wasted. When a television broadcast signal that is difficult to view is recorded as described above, a troublesome reproduction operation such as fast-forwarding and reproducing the difficult-to-view part is required during reproduction.

  In the case of the broadcast receiving device disclosed in Patent Document 1 described above, it is possible to reproduce while jumping a portion with many errors. To perform this jump reproduction, there are many errors apart from broadcast data during recording. It is necessary to record error location identification data indicating the location of broadcast data in a storage medium. For this reason, the storage area of the storage medium is used wastefully in the recorded part of the broadcast data with many errors out of the recorded broadcast data, and the error part identification data indicating the recording part of the broadcast data with many errors is stored. It will be used more wastefully in the recording part.

  In addition, in the case of the broadcast receiving device disclosed in Patent Document 1, broadcast data with many errors can be deleted based on the error location identification data. This deletion processing is performed once for broadcast data with many errors. After all the broadcast data including it is recorded, the broadcast data with many errors is deleted again.

  For this reason, since broadcast data with many errors is once recorded in a storage medium, until the broadcast data with many errors is deleted, the storage area of the storage medium is filled with the broadcast data with many errors. There is a problem of wasted use. Further, there is a problem that a complicated processing system for deleting broadcast data with many errors after recording is required.

  In addition, when a broadcast receiving device disclosed in Patent Document 1 is provided with a recording system capable of performing high-speed recording / reproducing on a storage medium, broadcast data with many errors is recorded after the broadcast data is temporarily recorded. It is possible to delete and re-record new broadcast data in the storage area formed by this deletion. However, to achieve this, a high-speed and complicated recording system is required, which is inevitably costly. There is a problem that becomes high.

The present invention has been made in view of the above problems,
1. When recording broadcast signals, the storage area of the storage medium can be used effectively,
2. Troublesome playback operations such as fast-forward playback of recorded locations where broadcast signals that are difficult to watch or listen to are recorded can be eliminated,
3. It is an object of the present invention to provide a portable terminal device and a broadcast signal recording method that can be realized at low cost with a simple system configuration.

The movement detection means detects that the mobile terminal device is moving, and the reception intensity of the broadcast signal detected by the reception intensity detection means is less than or equal to a predetermined reception intensity. If the mobile terminal device is moving and the reception intensity of the broadcast signal is equal to or less than a predetermined reception intensity, the compression encoding process performed by the compression encoding means is stopped and controlled. And a control means for stopping controlling recording of the compression coding processing broadcast signal to medium.

When the reception intensity of the broadcast signal detected in the step of detecting the reception intensity is greater than a predetermined reception intensity, the broadcast signal that has been compression-encoded by the compression encoding means is stored. The compression encoding means is driven and controlled so as to be stored in the medium. On the contrary,

[Broadcast signal recording operation]
The cellular phone according to the embodiment is configured such that the broadcast signal received by the television unit 11 or the radio unit 13 is externally connected to the memory 18 built in the cellular phone or externally connected to the cellular phone. It can be recorded in the memory 16. The user designates the recording destination of the broadcast signal in advance, and the control unit 19 stores the recording destination information indicating the recording destination of the broadcast signal in the memory 18 as a part of the setting information. When recording of the broadcast signal is designated by the user, the broadcast signal is recorded and controlled in the memory 18 designated by the user or the external memory 16 based on the recording destination information stored in the memory 18. It has become.

  In the following description, the operation of recording a broadcast signal (video and audio) of a television broadcast will be described as an example. However, the operation of recording a broadcast signal (audio) of a radio broadcast is similar to the operation of recording this television broadcast. Therefore, please refer to the following explanation.

  The flowchart of FIG. 2 shows the flow of the recording operation of the television broadcast signal in this mobile phone. This flowchart is executed by the control unit 19 based on a television signal processing program stored in the memory 18, and starts when a user selects a desired channel for television broadcasting. It becomes.

  That is, when a user selects a desired channel for television broadcasting, the control unit 19 selects a channel designated by the user based on the television signal processing program stored in the memory 18. Thus, the television unit 11 is channel-controlled. Then, the television broadcast video received by the channel selection control is displayed and controlled on the display unit 5, and the television broadcast sound is output controlled via the speaker unit 3. Thereby, the user can view a television broadcast of a desired channel.

  When the control unit 19 controls viewing of the television broadcast of the channel designated by the user in this way, in step S1, it is determined whether or not the recording designation operation of the television broadcast of the currently selected channel has been performed by the user. Start monitoring. Then, the process proceeds to step S2 at the timing when the recording designation operation of the television broadcast is detected.

  In step S2, the control unit 19 determines whether or not the mobile phone is currently moving. The control unit 19 determines whether or not the vehicle is moving by comparing the position information transmitted from the base station every predetermined time, or as shown by a dotted line block in FIG. When the GPS antenna 20 and the GPS unit 21 are provided in the telephone, the current position detected by the GPS antenna 20 and the GPS unit 21 is compared every predetermined time.

  If it is determined in step S2 that the mobile phone is not currently moving, it is considered that the user is watching the television broadcast in a good reception state with the position of the mobile phone fixed. Then, the control unit 19 advances the process to step S4, and performs recording control of the television broadcast signal of the currently selected channel.

  Specifically, a television broadcast signal (video signal and audio signal) of a channel currently selected by the television unit 11 is supplied to the encoder 15. Based on the “master clock” for setting the encoder 15 in a driving state and the frame synchronization signal added to the television broadcast signal received by the television unit 11, the control unit 19. The “frame synchronous clock” formed in this way is controlled.

  Based on the “master clock” and “frame synchronization clock”, the encoder 15 performs, for example, the MPEG-2 standard (MPEG) on the television broadcast signal (video signal and audio signal) of the currently selected channel. : Perform compression encoding processing based on Motion Picture Experts Group) and output.

  When the video signal and the audio signal subjected to the compression encoding process are output from the encoder 15, the control unit 19 controls to write these in a memory (external memory 16 or memory 18) selected in advance by the user. To do. As a result, the television broadcast signal of the currently selected channel is recorded.

  On the other hand, if it is determined in step S2 that the mobile phone is currently moving, it is considered that the user is watching the television broadcast in an unstable reception state while carrying the mobile phone. Therefore, the control unit 19 advances the processing to step S3, and whether or not the reception intensity of the currently selected channel television broadcast detected by the reception intensity detection unit 14 is equal to or lower than the predetermined reception intensity. Is determined.

  If the reception intensity of the television broadcast of the currently selected channel is a reception intensity having a value larger than the predetermined reception intensity, the process proceeds to step S4, and the channel currently being selected is not changed. The television broadcast signal of the channel is recorded and controlled in any one of the memories 16 and 18 described above. As a result, a television broadcast signal that is well received even during movement is recorded in one of the memories 16 and 18.

  On the other hand, when the reception intensity of the television broadcast of the currently selected channel is equal to or lower than the predetermined reception intensity, the process proceeds to step S6, and the control unit 19 performs the compression code of the encoder 15. Control stop processing.

  Specifically, as described above, the encoder 15 has a “master clock” for setting the encoder 15 in a driving state, and a frame synchronization signal added to the television broadcast signal received by the television unit 11. A “frame synchronization clock” formed based on the above is supplied.

  The encoder 15 is driven by the “master clock” and performs the compression encoding process of the television broadcast signal while synchronizing the frame by the “frame synchronization clock”. When it is detected that the intensity is less than or equal to the intensity, the “frame synchronization clock” supplied to the encoder 15 is stopped at this timing.

  As a result, the encoder 15 is held in the driving state by the “master clock”, but the “frame synchronization clock” is not supplied, and therefore the encoder 15 does not execute the compression encoding process. For this reason, the output of the above-mentioned compression-encoded television broadcast signal output from the encoder 15 is also stopped, and writing of the television broadcast signal to the external memory 16 or the memory 18 is also stopped. .

  Such “frame synchronization clock” supply stop control is determined in step S3 that the reception intensity of the television broadcast of the currently selected channel is greater than the predetermined reception intensity. At this time, the supply of the “frame synchronization clock” to the encoder 15 is resumed. Then, by restarting the supply of the “frame synchronization clock” to the encoder 15, the writing of the television broadcast signal to the external memory 16 or the memory 18 is also resumed.

  In other words, the encoder 15 is driven by the “master clock” and the “frame synchronization clock” while the reception intensity of the television broadcast of the currently selected channel is higher than the predetermined reception intensity. As long as the television broadcast signal is written to the external memory 16 or the memory 18 and the reception intensity of the television broadcast of the currently selected channel is below the predetermined reception intensity, the “frame synchronization clock” ”Is stopped, the compression encoding process of the encoder 15 is stopped, and the writing of the television broadcast signal to the external memory 16 or the memory 18 is controlled to stop.

  Such an operation will be described in more detail with reference to FIGS. 3 is a hardware diagram illustrating the supply stop control of the “frame synchronization clock”, FIG. 4 is a time chart of each signal and clock relating to this operation, and FIG. 5 is written in the external memory 16 or the memory 18. It is the figure which showed the television broadcast signal typically.

  The television unit 11 shown in FIG. 3 supplies the television broadcast signal of the channel selected as shown in FIG. 4A to the encoder 15 and also supplies it to the comparator 30 that forms the reception intensity detection unit 14. . In the case of the example shown in FIG. 4A, the reception intensity of the television broadcast signal is low between time t1 and time t2 and between time t3 and time t4, and good reception intensity between the other times. It is shown that.

  Further, as shown in FIG. 4B, the television unit 11 is synchronized with the frame synchronization signal based on the frame synchronization signal added to each frame of the television broadcast signal of the selected channel. A frame synchronization clock shown in FIG. 4D is formed and supplied to the AND gate 32.

  The comparator 30 is supplied with a reference signal from the comparison signal generator 31 in addition to the television broadcast signal. The value of the reference signal is a threshold value for reception intensity, and the comparator 30 outputs the high-level comparison signal to the AND gate 32 while the value of the television broadcast signal is larger than the value of the reference signal. The low-level comparison signal is supplied to the AND gate 32 while the value of the television broadcast signal is equal to or lower than the value of the reference signal.

  The AND gate 32 forms a “recording control clock” shown in FIG. 4 (e), in which the comparison signal from the comparator 30 and the frame synchronization signal from the television unit 11 are high only during the high level, This “recording control clock” is supplied to the encoder 15 as a frame synchronization clock. As a result, when the reception intensity of the television broadcast signal is high, a “recording control clock” that is at a high level in synchronization with the frame synchronization signal is supplied to the encoder 15, but the reception intensity of the television broadcast signal is high. A low-level “recording control clock” is supplied to the encoder 15 between the low time t1 and the time t2 and between the time t3 and the time t4.

  The encoder 15 is driven by the master clock shown in FIG. 4C and compresses the frame of the television broadcast signal supplied from the television unit 11 at the timing when the high-level “recording control clock” is supplied. When a low-level “recording control clock” is supplied, until the next high-level “recording control clock” is supplied, compression encoding of the frame of the television broadcast signal is performed. Stop processing. That is, in the case of the example shown in FIG. 4, the encoder 15 stops the compression encoding process of the frame of the television broadcast signal between time t1 and time t2 and between time t3 and time t4.

As a result, while the compression encoding process is stopped, the compression encoding output from the encoder 15 is also stopped, and the control unit 19 also stores any memory of the television broadcast signal subjected to the compression encoding process. Writing to 16 and 18 is also stopped. Therefore, as shown in FIG. 5, only the television broadcast signal received with good reception strength is continuously recorded in the external memory 16 or the memory 18.

[Effect of the embodiment]
As is clear from the above description, the mobile phone according to the present embodiment has the encoder 15 while the reception intensity of the television broadcast signal detected by the reception intensity detection unit 14 is lower than the predetermined reception intensity. Of the master clock and the frame synchronization clock supplied to the TV, the frame synchronization clock is controlled to stop (= the recording control clock is set to the low level), and the encoder 15 is held in the driving state, and the television Stops the compression encoding processing of the broadcast signal. As a result, the encoder 15 outputs a television broadcast signal that has been compression-encoded only while the television broadcast signal is being received with good reception strength. 18 can be recorded. For this reason, it is possible to continuously record only broadcast signals that have been successfully received, and to prevent inconvenience that the storage area of the memory is wasted due to the television broadcast signal having low reception intensity that is difficult to view, The storage area of the memory can be used effectively.

  In addition, it is possible to continuously record only a well-received television broadcast signal without recording a low-intensity television broadcast signal that is difficult to view. This eliminates the need for troublesome playback operations such as fast-forward playback of recorded locations.

Further, it can be realized with a simple system configuration in which the frame synchronization clock supplied to the encoder 15 is stopped and controlled while the reception intensity of the television broadcast signal is lower than the predetermined reception intensity. For this reason, it can be realized at low cost.

Then, it is encoded again by the encoder 15 and recorded in the external memory 16 or the like. At this time, the reception error amount is detected by the reception error detection unit, and this reception error amount is equal to or larger than a predetermined error amount. If there is, the encoder 15 is controlled to stop.
