Description

The present invention relates to a broadcast program recording method and system, and more particularly to a method and apparatus for recording a television broadcast program via a communication system.

  When an incoming call is received while watching a television broadcast program, the call is usually interrupted and the volume is lowered to make a call. During a call, you cannot watch the program. In order to eliminate such inconvenience, there has been proposed a method of automatically recording a TV broadcast program being viewed when a call is received.

  Japanese Patent Application Laid-Open No. 2001-333334 describes that a television receiver has a built-in modem and automatically records a TV broadcast program being viewed when a fixed telephone call is detected. This document further describes that a television receiver is provided with a communication antenna to automatically record a TV broadcast program being viewed when an incoming call from a mobile phone is detected.

  When a telephone call is received while using a household electric appliance, the electric appliance in use is usually stopped or turned off before making a call. After the call ends, return the electrical device switch to its original position. In order to eliminate such inconvenience, there has been proposed a method of automatically disconnecting a switch of an electrical device in use when an incoming call is received while the home electrical device is being used.

Japanese Patent Application Laid-Open No. 2002-27142 automatically pauses an electrical device in use or turns off the power when a call is received while using a household electrical device. It outputs that the signal for making it into. In this way, operations such as stopping the electrical device that have been conventionally performed until the incoming call is answered can be omitted.

  However, in the examples disclosed in Japanese Patent Application Laid-Open Nos. 2001-333334 and 2002-27142, it is necessary to manually perform a process of stopping the recording after the call ends and reproducing the recording. In addition, it is impossible to deal with the case where reception of TV broadcast radio waves becomes impossible due to radio wave interference or the like.

  A mobile communication device according to the present invention includes a broadcast signal receiving unit for receiving a broadcast signal, a received signal recording unit for recording broadcast reception information, and an incoming call for detecting incoming or outgoing call of mobile communication. And a recording start / recording stop / playback instruction information generation unit for generating recording start / recording stop / playback instruction information, and the incoming call detection unit receives a mobile communication during reception of a broadcast signal. When a call is detected, broadcast reception information being received is recorded in the reception signal recording unit.

  According to the present invention, a mobile communication device capable of receiving a television broadcast can be viewed when a television broadcast program cannot be viewed due to an outgoing call or an incoming call while the television broadcast program is being viewed. Since the program is automatically recorded, there is an advantage that a program that could not be viewed due to a telephone call can be viewed later.

  First, with reference to FIG. 1, an example of a recording system for a television (hereinafter simply referred to as television) broadcast program according to the present invention will be described. The television broadcast program recording system of this example includes a mobile communication device 20 capable of receiving a television broadcast, a recording server 30 for recording the television broadcast program, and a communication system. As shown in FIG. 1, the communication system may include a communication carrier 8, the Internet 5, and a gateway 6 via both.

  A mobile communication device 20 capable of receiving a television broadcast receives a mobile communication function unit 21 for executing mobile communication via a communication system, a mobile communication antenna 22, a display unit 23, and a TV broadcast radio wave broadcast from the TV broadcast station 12. A television broadcast receiving function unit 25 for receiving, a television broadcast receiving antenna 26 and a built-in recording device 27 are provided. The mobile communication function unit 21 may have a W-CDMA mobile communication function, for example. The TV broadcast receiving function unit 25 may have a function of receiving, for example, terrestrial digital television broadcast, but receives terrestrial analog television broadcast, BS (Broadcast Satellite) broadcast, CS (Communication Satellite) broadcast, and the like. It may have a function.

  The recording server 30 includes a television broadcast receiver 35, a television broadcast receiving antenna 36, and a recording device 37. Details of configuration examples of the mobile communication device 20 and the recording server 30 capable of receiving a television broadcast will be described later.

  A method of recording (recording) a television broadcast program using the television broadcast program recording system of this example will be described. It is assumed that the user receives a call from the communication partner 10 to the mobile communication device 20 while viewing the TV broadcast program by the mobile communication device 20 capable of receiving the television broadcast. Alternatively, it is assumed that a call is made from the mobile communication device 20 to the communication partner 10.

  According to this example, when the mobile communication device 20 detects an incoming call from the communication partner 10 or a call to the communication partner 10, the mobile communication device 20 records the TV broadcast program that the user is viewing. Note that the mobile communication device 20 may start recording a television broadcast program when it detects the start of a call rather than when it detects an incoming call or a call. However, in the following description, it is assumed that the TV broadcast program being viewed is recorded when an incoming call or a call is detected.

  Furthermore, an automatic recording mode and a manual recording mode may be provided. In the automatic recording mode, a TV broadcast program is automatically recorded when an incoming call or a call is detected, and in the manual recording mode, a TV broadcast program is recorded to the user when an incoming call or a call is detected. When the user gives an instruction for recording, the TV broadcast program is recorded. In this case, the display unit 23 indicates whether the automatic recording mode is currently set or the manual recording mode is set. However, in the following description, it is assumed that a television broadcast program is automatically recorded when an incoming call or a call is detected.

  When the call with the communication partner 10 is finished, the recording of the TV broadcast program is stopped. The user can view the portion of the program that could not be viewed during a call by playing the recorded television broadcast program.

  The program recording destination is the internal recording device 27 of the mobile communication device 20 or the recording device 37 of the recording server 30. When recording a program in the built-in recording device 27 of the mobile communication device 20, the mobile communication device 20 outputs a recording command to the built-in recording device 27 when detecting a call or an incoming call. When detecting the end of communication, the mobile communication device 20 outputs a recording stop command to the built-in recording device 27.

  When recording in the recording device 37 of the recording server 30, the mobile communication device 20 transmits a recording command to the recording server 30.

The television broadcast receiver 35 provided in the recording server 30 receives the television broadcast radio wave via the television broadcast receiving antenna 36 and records the received television broadcast program in the recording device 37. Similarly, the recording stop command from the mobile communication device 20 is transmitted to the recording server 30.

  Furthermore, according to this example, the mobile communication device 20 transmits a recording command to the recording server 30 when the user detects a radio wave interference in the television broadcast while viewing the television broadcast program. The recording server 30 records a television broadcast program in the recording device 37. When the radio interference is recovered, the mobile communication device 20 transmits a recording stop command to the recording server 30. The user can view the portion of the program that could not be viewed during radio wave interference by playing the television broadcast program recorded on the recording server 30.

  In the example shown in FIG. 1, the built-in recording device 27 of the mobile communication device 20 or the recording device 37 of the recording server 30 is used as the program recording destination, but other recording destinations are also possible. For example, another portable recording device (not shown) may be used as a program recording destination using short-range wireless communication such as Blue Tooth. In this case, like the built-in recording device 27, it cannot be used in the case of radio interference.

  Further, in the example of FIG. 1, the case of recording a TV broadcast program has been described, but all programs, information, etc. broadcasted by the TV broadcast station 12 such as digital teletext broadcasting, digital music broadcasting, program information, etc. are described by the same method. Can be recorded.

  In the case of a W-CDMA mobile communication device, incoming / outgoing calls for mobile communication and Internet connection can be executed simultaneously. However, when an incoming / outgoing call for mobile communication and connection to the Internet cannot be executed simultaneously as in a normal cellular phone, a dual antenna or the like may be provided. Thereby, a recording command can be transmitted to the recording server 30 via the Internet.

  With reference to FIG. 2, the example of a structure of the mobile communication apparatus 20 which can receive television broadcast by this invention is demonstrated. The mobile communication device 20 of the present example records a broadcast signal receiving unit 222 for receiving a television broadcast signal, a broadcast reception information converting unit 223 for converting the broadcast signal into broadcast reception information, and recording the broadcast reception information.

  The TV broadcast signal is received by the broadcast signal receiving unit 222 via the TV broadcast receiving antenna 26, and further converted into an image signal, that is, broadcast reception information by the broadcast reception information converting unit 223. The broadcast reception information is recorded by the reception signal recording unit 224 and reproduced by the reproduction unit 233 by the method described below.

  The recording state detection unit 225 monitors the recording state in the reception signal recording unit 224 and notifies the recording start / recording start / recording stop / reproduction instruction information generation unit 228 whether the recording is possible or impossible. The reception status detection unit 226 detects the reception status of the television broadcast signal and notifies the recording start / recording stop / playback instruction information generation unit 228 of the television broadcast reception status. The incoming / outgoing call detection unit 227 detects an incoming / outgoing call / call disconnection, and notifies the recording start / recording stop / reproduction instruction information generation unit 228 of the call status.

  The recording start / recording stop / reproduction instruction information generation unit 228 generates recording start instruction information, recording stop instruction information, or reproduction instruction information according to the recording state, broadcast reception status, and call status, and manages recording / reproduction instruction information transmission destinations Notification to the unit 229. The recording / playback instruction information transmission destination management unit 229 notifies the recording destination set by the user of a recording / playback instruction.

  When the recording destination is the built-in recording device 27, the recording / playback instruction information transmission destination management unit 229 notifies the reception signal recording unit 224 of the recording instruction and notifies the playback unit 233 of the playback instruction. When the recording destination is the external recording server 30, the recording / reproduction instruction information transmission destination management unit 229 transmits the recording / reproduction instruction information to the recording / reproduction instruction information transmission unit 230. The recording / reproduction instruction information transmission unit 230 transmits the recording / reproduction instruction information to the recording server 30 via the communication network.

  The reproduction information receiving unit 231 receives the reproduction information from the communication network or the reception signal recording unit 224 and transmits it to the reproduction information conversion unit 232. The reproduction information conversion unit 232 converts the reproduction information into image information and transmits the image information to the reproduction unit 233. The reproduction unit 233 reproduces the image information based on the reproduction instruction from the recording / reproduction instruction information transmission destination management unit 229.

With reference to FIGS. 3 and 4, an example of a method for controlling a mobile communication apparatus capable of receiving a television broadcast according to the present invention will be described.
First, in step S001 of FIG. 3, it is assumed that the user is watching a television broadcast program by the mobile communication apparatus capable of receiving the television broadcast of this example. In step S002, it is determined whether or not mobile communication has been called or received while viewing a television broadcast program, or viewing of a television broadcast program has become impossible. When viewing of a TV broadcast program is impossible, for example, reception of TV broadcast radio waves due to radio wave interference or the like may be impossible. If a call is made or received, or if viewing is disabled, it is determined in step S003 whether a recording destination for the television broadcast program is set. If the recording destination is set, the process proceeds to step S005.

  If the recording destination has not been set, the user is requested to set the recording destination in step S004. However, in the case of radio interference, the recording device 27 of the mobile communication device 20 cannot be designated as the recording destination. When the recording destination is set by the user, the process proceeds to step S005.

  In step S005, it is determined whether the recording destination set by the user is the internal recording device 27 of the mobile communication device 20 or the recording device 37 of the external recording server 30. If the recording destination is the internal recording device 27 of the mobile communication device 20, a recording start instruction is transmitted to the internal recording device 27 in step S006. In step S007, the built-in recording device 27 of the mobile communication device 20 starts recording the TV broadcast program being viewed. Then, in step S009, it waits for recovery of call disconnection or radio wave interference.

  If the recording destination is the external recording server 30, the recording / playback instruction information transmitting unit 230 of the mobile communication device 20 transmits recording start instruction information to the external recording server 30 in step S 008. The recording server 30 records the television broadcast program being viewed by the user in the recording device 37. Then, in step S009, it waits for recovery of call disconnection or radio wave interference.

  Next, in step S010 in FIG. 4, a call waiting or recovery from radio wave interference is awaited. In step S011, it is determined whether the call has been disconnected or the radio wave has been recovered. If the call is disconnected or the radio wave interference is recovered, it is determined in step S012 whether or not “recovery processing setting” has been made. “Processing setting after recovery” is to set in advance to execute, for example, recording stop, recording continuation, recording / reproducing, etc. after a call disconnection or after recovery from radio wave interference.

  If processing after recovery is set, the process proceeds to step S014. If the post-recovery process setting has not been made, the user is asked for the post-recovery process setting in step S013. When the user has made recovery settings, the process proceeds to step S014.

  In step S014, it is determined whether the recording destination is the internal recording device 27 of the mobile communication device 20 or the recording device 37 of the external recording server 30. If the recording destination is the built-in recording device 27 of the mobile communication device 20, the instruction selected in the setting of the process after recovery is executed in step S015. For example, the recording / playback instruction information transmission destination management unit 229 instructs the reception signal recording unit 224 to stop recording, or instructs the playback unit 233 to play back the program recorded in the internal recording device 27. To do. If the recording destination is the recording device 37 of the recording server 30, in step S016, the recording / playback instruction information transmitting unit 230 of the mobile communication device 20 sends the instruction selected in the setting of the process after recovery to the external Transmit to the recording server 30. For example, the program recorded in the recording device 37 of the external recording server 30 is reproduced. After that, in step S017, the process proceeds to a call waiting or incoming call / radio wave interference waiting state.

  According to the method of this example, a television broadcast program is automatically recorded when a mobile communication call is made or received, or when a television broadcast program cannot be viewed due to radio interference or the like. When the mobile communication is disconnected or the radio wave interference is recovered, the recording is stopped and the recorded television broadcast program is reproduced. Therefore, it is possible to view a television broadcast program that could not be viewed during a call or during radio wave interference. Processing such as start of recording, stop of recording, continuation of recording, and reproduction may be automatically executed.

  With reference to FIG. 5, an example of a recording continuation method using the mobile communication device 20 capable of receiving a television broadcast according to the present invention will be described. First, in step S018, a television broadcast program is recorded in the built-in recording device 27 of the mobile communication device 20 capable of receiving the television broadcast of this example. In step S019, it is determined whether the recording status detection unit 225 of the mobile communication device 20 detects that recording is impossible or the reception status detection unit 226 detects a radio wave interference during the recording of the television broadcast program. When the recording state detection unit 225 detects that recording is impossible, for example, when the recording capacity of the internal recording device 27 is smaller than a predetermined amount, when the internal recording device 27 is used by another device, etc. There is. If the recording state detection unit 225 detects that recording is impossible, or if the reception state detection unit 226 detects radio wave interference, the process proceeds to step S020.

  In step S020, it is determined whether a second recording destination for continuing recording is set. If the second recording destination is set, the process proceeds to step S022. If the second recording destination is not set, the user is asked to set the second recording destination in step S021. When the user sets the second recording destination, the process proceeds to step S022.

  In step S022, the recording start / recording stop / reproduction instruction information generation unit 228 transmits the recording start instruction information to the second recording destination, for example, the external recording server 30. As a result, recording can be continued in the recording device 37 of the external recording server 30. Thereafter, in step S023, the process proceeds to a call waiting / call waiting / radio wave interference waiting state.

  With reference to FIG. 6, the example of the recording / reproducing instruction | indication method using the mobile communication apparatus 20 which can receive television broadcast by this invention is demonstrated. In this example, a television broadcast program is recorded on the external recording server 30. First, in step S024, the mobile communication device capable of receiving a television broadcast of this example receives a television broadcast signal, and a user views a television broadcast program. In step S025, it is determined whether or not the mobile communication has been called or received during viewing of the television broadcast program, or whether or not the television broadcast program cannot be viewed due to radio wave interference. When a call is made or received for mobile communication, or when it is impossible to view a television broadcast program, in step S026, the recording start / recording stop / reproduction instruction information generation unit 228 displays an instruction time measurement unit. At 234, the recording start instruction time A is stored, and the recording start instruction information is transmitted to the external recording server 30.

  In step S027, it is determined whether the call has been disconnected or the radio wave interference has been recovered. If the call is interrupted or the radio wave interference is recovered, in step S028, the recording start / recording stop / reproduction instruction information generation unit 228 stores the reproduction start time B in the instruction time measurement unit 234, and The reproduction start instruction information is transmitted to the recording server 30.

  In step S029, it is determined whether or not all data recorded in the recording device 37 of the external recording server 30 has been reproduced. The difference B−A between the reproduction start time B and the recording start instruction time A stored in the instruction time measuring unit 234 is the recording time. The recording start / stop recording / reproduction instruction information generation unit 228 determines whether or not all data recorded in the recording device 37 has been reproduced by determining whether or not the recording time B-A has elapsed. can do.

  In step S030, the recording start / recording stop / reproduction instruction information generation unit 228 transmits reproduction end instruction information to the external recording server 30 when detecting that the recording time B-A has elapsed. The external recording server 30 stops the reproduction process. In step S031, the chasing playback or the recording is continued using the built-in recording device 27 of the mobile communication device 20.

  In this way, in this example, a television broadcast program is recorded on the external recording server from the occurrence of a call or incoming call or radio disturbance to the call disconnection or recovery from the radio disturbance. Furthermore, the portion recorded in the external recording server 30 is automatically reproduced when the call is disconnected or the radio wave is recovered, and at the same time, the TV broadcast program is recorded by the built-in recording device 27 of the mobile communication device 20. When the reproduction by the external recording server 30 is finished, the television broadcast program recorded in the built-in recording device 27 may be reproduced.
