Description

  The present invention has an HDMI terminal which is an input / output terminal for a digital video signal compliant with the HDMI (High Definition Multimedia Interface) standard, and can be connected to a television receiver compliant with the HDMI standard via an HDMI cable. More particularly, the present invention relates to an information recording / reproducing apparatus having a constant recording function for constantly recording data for a predetermined time according to a reception channel of a television receiving apparatus.

  In an information recording / reproducing apparatus for recording (recording) and reproducing broadcast data including video such as a television program, data for a predetermined time is always stored in accordance with the reception channel of the television receiver, such as a hard disk recorder. Some have a constant recording function for recording. A time shift function is realized in which data recorded temporarily in a predetermined recording area of the hard disk is read using this continuous recording function, and is played back up to the predetermined time at the maximum.

  By the way, in order to realize the continuous recording function and the time shift function by such an information recording / reproducing apparatus, it is necessary to consider the interlocking with the connected television receiver, and considering this interlocking, An apparatus for the convenience of the user is disclosed (for example, see Patent Document 1).

  In the device described in Patent Document 1, when a user instructs power-on using a remote controller, a system power supply is activated, and in response to this, a power-on reset pulse generation circuit outputs a reset pulse signal and inputs it to a microcomputer. The microcomputer that received the reset pulse signal reproduces the last channel state before the previous power-off, inputs the selected program to the simultaneous recording / playback circuit, and inputs the recording start command to the simultaneous recording / playback circuit. The recording / playback circuit starts to constantly record the selected program. That is, the user can always start recording simply by operating the remote control of the television receiver.

However, the apparatus described in Patent Document 1 has a structure in which an information recording / reproducing apparatus is integrally incorporated in a television receiving apparatus.

  However, when the information recording / reproducing apparatus is connected to the external input terminal of the television receiving apparatus using a signal cable, the above command is easily transferred between the information recording / reproducing apparatus and the television receiving apparatus. In such a connection structure, after turning on the power of the television receiver, it is necessary to turn on the information recording / reproducing device to start the continuous recording function, which is troublesome for the user. Met.

  In addition, in the conventional continuous recording function, when the reception channel of the television receiver is switched to another channel during continuous recording, the continuous recording channel is switched to another channel accordingly. Yes. In this case, for example, when the program currently being viewed enters the CM (commercial), the user switches to another channel only during that time, and then returns to the original channel at the time when the CM would have ended. Is often done. Then, when returning to the original channel, if the CM has already ended and the continuation of the program has started, the first part of the program after the CM will be missed. In this case, in the conventional continuous recording function, a program corresponding to the user's channel switching is recorded. Therefore, even if the program is rewound and played back, the program portion that was overlooked cannot be played back. There is a problem that the recording function is not fully utilized, that is, the recording is not always performed in consideration of user convenience.

  By the way, in recent years, with the progress of the liquid crystal panel manufacturing technology, the display screen of a television receiver used in an information recording / reproducing apparatus such as a DVD recorder or a hard disk (HD) built-in DVD recorder has been improved in definition. In a television receiver and an information recording / reproducing apparatus, an interface circuit compatible with HDMI (High Definition Multimedia Interface) is used to transmit and receive a large amount of video data and audio data.

  HDMI is an interface for transmitting and receiving various data including video data and audio data between a transmitting device such as a DVD recorder or a built-in DVD recorder and a receiving device such as a television receiver or a projector. With the HDMI CEC control function, for example, when the power of a television receiver or the like is turned on, the information recording / reproducing device can be turned on.

  The present invention was devised to solve the above problems by paying attention to the CEC control function of the HDMI standard, and the object thereof is a predetermined time according to the reception channel of the television receiver connected by the HDMI cable. It is an object of the present invention to provide an information recording / reproducing apparatus that improves the usability of a constant recording function for constantly recording minute data.

  In order to solve the above-described problems, an information recording / reproducing apparatus of the present invention includes an interface circuit capable of acquiring the operating state of a television receiving device connected to an external connection terminal, and matches the reception channel of the television receiving device. In an information recording / reproducing apparatus having a constant recording function for continuously recording data for a predetermined time, the recording control means for executing the continuous recording detects the power of the television receiving apparatus when detecting that the television receiving apparatus is turned on. Turn on the power and start continuous recording. If the reception channel of the television receiver is switched from the first channel to another channel during the continuous recording, the recording channel is switched accordingly and the continuous recording is performed. And when it detects that the power of the television receiver is turned off, it turns off the power of its own device. It is a symptom. Here, the interface circuit is an HDMI compatible interface circuit, and the external connection terminal is an HDMI terminal.

  That is, in the CEC control function of the HDMI standard, various control data can be transmitted and received using the CEC line of the HDMI cable, and the information recording / reproducing apparatus uses the CEC line to turn on the television receiver. Information such as off and channel switching can be acquired. Similarly, also in a television receiver, it is possible to acquire information on the power on / off of the information recording / reproducing apparatus and the recording / reproducing state.

  Therefore, according to the present invention, when information indicating that the power of the television receiver is turned on is obtained through the CEC line using the HDMI standard CEC control function, the self-device is turned on and always recorded. To start. That is, channel information received by the television receiving apparatus at this time is acquired from the television receiving apparatus via the CEC line, and its own tuner is adjusted to the receiving channel to start continuous recording. When the reception channel of the television receiving device is switched from the first channel being received to another channel during the regular recording, the recording channel is switched following this and the continuous recording is continued. Then, when information indicating that the power of the television receiver is turned off is acquired via the CEC line during such continuous recording, the power of the own device is turned off. As a result, according to the information recording / reproducing apparatus of the present invention, although the external connection terminal of the television receiver is externally attached, the recording and the time shift are always performed by using the power of the television receiver as a trigger. It becomes possible to start.

  Also, according to the information recording / reproducing apparatus of the present invention, the recording control means receives the first channel received data when the receiving channel of the television receiving apparatus is switched from the first channel to another channel during continuous recording. Is CM data, the received data of the first channel up to that time is continuously recorded without following the channel switching of the television receiver, and the TV is not changed even if a predetermined time elapses. When the reception channel of the John reception device does not return to the original first channel, the constantly recording channel may be switched to the current channel received by the television reception device at that time. Here, the predetermined time is set to a time (for example, 3 minutes) slightly longer than the continuous broadcast time of one CM. In addition, the first channel referred to here is a reception channel at that time of the television receiver when the power of the television receiver is turned on. That is, the channel that was viewed immediately before the television receiver was turned off last time.

  That is, the recording control means obtains information indicating that the reception channel of the television receiving apparatus has been switched from the first channel currently being received to another channel through the CEC line during continuous recording. It is determined whether or not the received data of the first channel is CM data. In this case, since the information recording / reproducing apparatus receives the broadcast data by its own tuner, even if the channel on the television receiving apparatus side is switched, the information recording / reproducing apparatus receives the original first channel broadcast data before switching. Thus, the presence or absence of CM data can be determined.

  As a result, when the broadcast data of the first channel is CM data, the received data of the first channel up to that time is continuously recorded without following the channel switching of the television receiver. At this time, the recording control unit activates the timer unit and starts measuring a certain time that is slightly longer than the CM broadcast time. If the reception channel of the television receiver does not return to the original first channel even after a certain period of time has elapsed, the current channel on which the television receiver is receiving the constantly recorded channel at that time. Switch to.

  On the other hand, when information indicating that the reception channel of the television receiver has returned to the original first channel is acquired via the CEC line before a certain time has elapsed, continuous recording is continued on the channel as it is. . That is, in this case, even if the channel of the television receiver is switched from the original first channel to another channel for only a few minutes, the information recording / reproducing apparatus continues the broadcast data of the original first channel. And always recording. Therefore, when the user returns the channel of the television receiver to the original first channel, the information recording / reproducing apparatus can be rewound and reproduced even if the CM has already ended and the continuation of the program has started. Thus, it is possible to view from the continuation of the program immediately after the missed CM ends.

  Also, according to the information recording / reproducing apparatus of the present invention, the recording control means receives the first channel received data when the receiving channel of the television receiving apparatus is switched from the first channel to another channel during continuous recording. Is the CM data, the received data of the first channel up to that time is continuously recorded without following the channel switching of the television receiver, and after the completion of the reception of the CM data, a predetermined constant is set. If the reception channel of the television receiver does not return to the first channel even after a lapse of time, the constantly recording channel may be switched to the channel received by the television receiver at that time. Here, the fixed time is, for example, 30 seconds to 1 minute. In this way, by measuring a certain time using the end of CM as a trigger, it is always determined whether or not the channel for continuous recording has been switched at the same time after the end of CM regardless of the length of the CM data broadcast time. Can do.

  According to the information recording / reproducing apparatus of the present invention, although the external connection terminal of the television receiver is externally attached, the constant recording and the continuous time shift are started by using the power of the television receiver as a trigger. Can do.

  Further, according to the information recording / reproducing apparatus of the present invention, the reception data of the first channel when the reception channel of the television receiving apparatus is switched from the first channel to another channel during constant recording is CM data. In such a case, the received data of the first channel up to that time is continuously recorded without following the channel switching of the television receiving device, and even if a predetermined time has elapsed, the reception of the television receiving device is continued. When the channel does not return to the original first channel, the constantly-recorded channel is switched to the current channel received by the television receiver at that time, so that the user can change the channel of the television receiver. When returning to the original channel 1, the CM has already ended and the continuation of the program has started. Also by rewind playback information recording and reproducing apparatus, in which the user can view the rest of the missed CM immediately after the end of the program. Thereby, it is possible to realize continuous recording and continuous time shift in consideration of user convenience.
