Description

  The present invention relates to a recording / playback apparatus and a recording / playback system, and more particularly to an operation history processing method thereof.

For example, Patent Document 1 discloses a portable terminal with a recording / playback function that can record broadcast contents during a call and reproduce the recorded contents later on the portable terminal.
Patent Document 2 discloses a remote setting system for a television broadcast receiving apparatus that can perform various settings for a television broadcast receiving apparatus placed at home or the like using a remote terminal. Yes.

  Patent Document 3 discloses a device other than a device (P D A) that currently reproduces content by transferring a memory card that records history information from the PD A to the HDD recording / reproducing device. Also shown is a video / audio reproduction apparatus capable of automatically reproducing the continuation of the same program.

  In general, when watching TV (TV) broadcasting, the user's preference for viewing differs between viewing using a mobile terminal and viewing using a receiver or a recording / playback apparatus placed in the home. For example, when watching a program on a mobile terminal when going out, there are restrictions on the size of the display screen that comes from the housing size considering portability. There are many cases of watching a program with a breaking news. On the other hand, viewing using an indoor receiver or recording / playback apparatus has no limitation on the screen size and has a degree of freedom of installation, and therefore, a user often enjoys clear and powerful video and audio on a large screen.

  However, when viewing of TV broadcasts using mobile devices becomes widespread, if you want to watch a program you watch while you are out on the big screen again after you go home, or watch a part of the program when you are away from home, There is a demand for watching the continuation, before and after, or from the beginning to the end of the program on the indoor recording / playback apparatus after returning home.

  By the way, the state of viewing performed using a portable terminal is not usually reflected in an indoor (home) receiver or recording / playback apparatus. For this reason, the user has no choice but to rely on his / her memory for information such as how far the program has been watched and thus from which scene he / she wants to watch.

  Patent Documents 1 and 2 show a method of viewing and recording / playback only with a portable terminal. However, there is no disclosure regarding a technique for improving usability in cooperation with an external device such as a recording / playback apparatus. In addition, a terminal that remotely controls recording settings of the recording / playback apparatus and setting changes of the receiving apparatus is described. However, it does not show usability when the terminal receives TV broadcasting or the like.

  Patent Document 3 discloses that a viewing history is transferred via a memory card. However, the video / audio reproduction device must be operated using the operation unit of the device. In other words, it is required to become familiar with the operation of two types of devices (PDA and recording / playback apparatus). For this reason, improvement in usability cannot be expected.

On the other hand, in Patent Document 4, all the broadcast programs are recorded so that the content that the user was watching on the go can be viewed again after returning home, but the user is actually viewing the content. There was a problem that it was far from the convenience of recording only the program.
JP 2003-348510 A JP 2002-57953 A JP 2003-304477 A Japanese Patent Laying-Open No. 2007-251280 (FIG. 8)

  Now, in the present embodiment, devices such as 4-6-8 in FIG. 6 that have a function of viewing broadcast programs in real time and transmitting information on the viewing state, and those in 2 of FIG. The present invention relates to a device having a function of analyzing viewing information transmitted in real time from a device and automatically recording a broadcast program based on the result.

Devices having a TV function such as 4 and 6-8 in FIG. 6 are classified into a stationary type and a portable type according to user settings. A stationary type is a device that is mainly intended for viewing broadcast programs at home, and that can stably receive and view broadcast waves (eg, LCD TVs, personal computers with TV functions, etc.) and is portable. Is a device whose main purpose is to receive broadcast waves outdoors and to watch broadcast programs outside the home (eg mobile phones, car navigation systems, portable music players, etc.) However, this is set by the user It does not depend on the form or nature of the device.

Further, 2 in FIG. 6 is an apparatus having a function of recording a broadcast program, and the main purpose is to record and reproduce the broadcast program in an environment where broadcast waves can be stably received (eg, HDD recorder, 6) The apparatus 2 in FIG. 6 may be the same as the stationary apparatus as 4 in FIG. 6 (eg, a TV with a recording function).

As a specific example, an example in which a home TV is selected as the stationary device in FIG. 6, a mobile phone having a one-segment broadcasting reception function is selected as the portable device, and an HDD recorder in the home is selected as the recording / playback device. Indicates.

Users routinely watch broadcast programs on their home TV, and use a HDD recorder for recording purposes for scheduled recording. Also, when you go out, you can watch a broadcast program with the 1Seg function of your mobile phone while you are on the move or in a little free time. However, when viewing a broadcast program when going out, it is difficult to view the broadcast program in a satisfactory environment due to radio wave conditions when riding on a train or car. Therefore, in order to solve these problems, the viewing status is sent to the HDD recorder in the home via a public wireless LAN, mail function, or IP communication for devices such as mobile phones that enjoy broadcast programs when going out. A function is added and the HDD recorder analyzes these viewing conditions to record the program that the user is currently viewing in a stable environment at home, and turn on the TV when the user returns home. Then, by notifying that the program is recorded after the user's inquiry, an environment in which the broadcast program can be viewed more easily is provided.

FIG. 7 shows an example of real-time viewing history information actually sent to the HDD recorder. The viewing history information is transmitted when the user performs some action on the device that is currently viewing. The information to be transmitted includes the date and time when the action was performed, program information for uniquely identifying which program is selected after the action, a unique ID for identifying the device on which the action was performed, and , Comprising information indicating the state of the device as a result of its action. However, this action represents both what the user has consciously performed and the situation that has resulted from the user's action. For example, as shown by 107 in FIG. 7, a case where a broadcast wave cannot be received for some reason is one of the actions. As described above, the recording / playback apparatus in the home receives the real-time viewing history data as shown in FIG. 7, and determines whether to record the program being viewed by the user based on the information sent from which device.

FIG. 8 shows a mechanism for determining whether or not to automatically record when the recording device receives viewing history data. First, in the state of step S201, it is determined whether the sent information is information indicating viewing. If the information indicates viewing, it is next determined in step S202 whether the information is sent from a portable device or information sent from a stationary device. This determination is made based on the unique ID of the device. If the information is from a stationary device, it is determined that the user is watching a broadcast program in a stable environment, and the recording / playback apparatus does nothing. If it is information from the portable device, it is determined whether the program that the user is currently viewing can be recorded in the state of step S203, and if it is determined that recording is possible, automatic recording is started as in step S205. .

Also, if it is not viewing information in step S201, it is next determined in step S204 whether the information indicates a situation where viewing is impossible, and if the user is unable to view from that time for some reason. Stores the time in step S206. These times when viewing is impossible include when the user explicitly ends viewing. When the user returns home and starts the recording / playback device, the time information is displayed in the form shown in FIG. It becomes possible to do. At this time, the program can be viewed again from the recording start time.

A second embodiment of the present invention will be described with reference to FIGS. 1 to 7 and FIG. Description of the parts common to the first embodiment is omitted.
The recording / playback apparatus 2 grasps the programs viewed in real time on a daily basis by analyzing the real-time viewing history of the registered apparatus having the TV functions 4 and 6-8 in FIG. 6, as shown in FIG. In addition, when a certain program is started, the program is always viewed in real time (YES in step S301) and is not currently viewed by a stationary device (NO in step S302). The program is automatically recorded (step S303). Accordingly, it is possible to prevent a user from watching a broadcast program that is being watched on a daily basis but not yet being recorded due to an unexpected situation.

A function for transmitting viewing history information in real time is added to a device having a TV viewing function, and the above viewing history information is received for a device having a function for recording and reproducing broadcasts in a stable environment. Equipped with an analysis function that allows users to watch broadcast programs stably, can easily watch broadcast programs on the go, and programs that they watch daily cannot be viewed due to unforeseen circumstances It became possible to prevent.

(Effect of embodiment)
One of the prior arts requires recording all the programs for 24 hours, which is very costly for the current digital broadcasting system, and it is necessary to operate the equipment 24 hours a day, 365 days a year. Also, the load on the environment, such as power, is high. However, in the method of the present embodiment, only the content that the user is actually watching outdoors is recorded, so the programs to be recorded are limited, and there is no need to always record. Since a program that has not been noticed by the user is basically wasted, the technique of this embodiment can satisfy the request to some extent.

In addition, this invention is not limited to the said embodiment, In the range which does not deviate from the summary, it can implement in various modifications.
Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements according to different embodiments may be appropriately combined.
