Reference numeral  104  indicates a log operating unit comprising a log acquiring means  127  and a contents information sending or transmitting means  129 . 
   Functions and operations of respective elements of structure employed in the system shown in  FIG. 1  will be described with reference to the function block diagram. The function block diagram of the in-home device is in  FIG. 2 . In  FIG. 2 , reference numeral  201  indicates an AV function control means having the function of reproducing or recording/reproducing contents information. The AV function control means  201  notifies user operations such as upper and lower key operations made upon selection of contents, or a user-operated result such as contents information selected by a user operation to a user-designated information acquiring means as user-designated information. Reference numeral  202  indicates the user-designated information acquiring means capable of acquiring or obtaining the user-designated information and holding the user-designated information or user-designated characteristic information indicative of the characteristic of the user-designated information therein as stored user-designated information. The user-designated characteristic information may include accumulative audience times or the like set every contents information, which are obtained by acquiring information about the occurrence of selectively switching between the respective contents information from the user-designated information and about the time of occurrence of the selective changeover and performing calculations based on them. Reference numeral  203  indicates a user-designated information notifying means capable of ON/OFF-controlling the output of the user-designated information according to notice control information  210  and outputting the result of ON/OFF control on the user-designated information as log information.

Reference numeral  204  indicates a user-designated information notification control means for performing switching control on the user-designated information notifying means  203  according to log accuracy information. Reference numeral  212  indicates a log storing and transmitting means for storing or accumulating log information  213  outputted from the user-designated information notifying means  203  and log accuracy information  214  outputted from the user-designated information notification control means  204  and transmitting or optionally transmitting the same. 
   Incidentally, while the user-designated information is notified to the user-designated information notifying means  203  in the present embodiment, the user-designated characteristic information may also be notified thereto. 
   While the information processing apparatus is described as the in-home device, it may similarly be implemented even as a device placed outside the home. 
   The operation of the in-home device will be explained below with reference to  FIG. 2 . The AV function control means  201  notifies a user operation  206  indicative of a user&#39;s operation made to the AV function control means  201  to the user-designated information acquiring means  202  as user-operated information  208  in accordance with one used for the setting of a predetermined AV function relation corresponding to the user operation. The user-designated information acquiring means  202  generates user-designated information  209  from the user-operated information  208  and notifies it to the user-designated information notifying means  203 . The operation of the user-designated information notifying means  203  will be explained using  FIG. 3 . The user-designated information accuracy setting means  205  notifies an accuracy setting  207  set by a user to the user-designated information notification control means as accuracy setting information  211 . An example shown in  FIG. 3  has shown where the user operates such a setting screen as shown in  FIG. 12  by way of example to thereby set accuracy information to 40%. In response to it, the user-designated information notification control means  240  generates notice control information  210  in which the ratio between periods of “H” and “L” designated at numeral  210  shown in  FIG. 3  is given as 40:60. While the period or cycle of this signal is not limited to it, the period thereof will be defined as a cycle of one hour, for example. When the notice control information  210  is “H”, the user-designated information notifying means  203  outputs user-designated information  209  as log information  213 . When the notice control information  210  is “L”, the user-designated information notifying means  203  outputs “L” (indicative of the absence of information) as log information  213 . The log information  213  is notified to the log accumulation controller  103  through the log storing and transmitting means  212  as log information  116 . The log information outputted from the log storing and transmitting means  212  is designated at numeral  116  in  FIG. 3 . It is understood that as to 40% of the entire log information, which is specified by the user&#39;s accuracy setting, log information obtained from user-designated information with a actual user operation as a base is transmitted, whereas as to the remaining 60%, user-designated information is masked so that no log information is transmitted. Thus, the log information  116  includes user-designated information corresponding to a desired log accuracy set by a user. 
   Thus, according to the in-home device of the present embodiment described in  FIG. 2 , the accuracy of the log information can be changed according to the setting of accuracy of each log set by the user. 
   Incidentally, while the present embodiment has adopted the configuration in which the in-home device is implemented by hardware such as a CPU and memory or the like and software such as programs and data or the like, it may use a configuration in which some or all of the functions of the in-home device are implemented as software operated by another information processing apparatus such as a PC or the like, a system which is implemented as software operated by other information processing apparatuses connected to one another by a network and processes only their input/output functions by means of in-home devices, etc. No particular limitation is imposed on a method of implementing the function of each in-home device. 
   For instance, a configuration may also be adopted wherein at leas some of the functions of the user-designated information acquiring means, user-designated information notifying means, user-designated notification control means, user-designated information accuracy setting means, log storing and transmitting means, etc. all of which constitute each in-home device, are implemented as software and executed by means other than the in-home device, such as the log accumulation controller or the like. According to such a configuration, part of the function of the in-home device can be shifted to the center side as in the case of the log accumulation controller or the like, and hence the required function of the in-home device can be reduced. 
   The operation of the log storage or accumulation controller will be described below using  FIG. 7 . In  FIG. 7 , reference numeral  118  indicates an accumulating device capable of receiving log information and log accuracy information from at least two in-home devices, reference numeral  701  indicates a storage means specifying means for recording the log information  121  accumulated by the accumulating device in storage means corresponding to at least two log accuracy classifications according to log accuracy information  122 , reference numerals  702 ,  703  and  704  indicate memory or storage means such as hard disk or the like, reference numeral  119  indicates a log recording device comprising the storage means specifying means  701  and the storage means  702 ,  703  and  704 , and reference numeral  120  indicates a log delivery device capable of notifying log accuracy designation information  124  corresponding to notice information for specifying a log accuracy to the storage means specifying means  701 , acquiring corresponding by-accuracy log information  123  from the storage means specifying means  701  and transmitting the acquired by-accuracy log information  123  to its corresponding log acquiring means. 
   In the log accumulation controller described in  FIG. 7 , the log information  121  and log accuracy information  122  transmitted from at least two in-home devices are received by the accumulating device  118  and notified to the storage means specifying means  701  lying within the log recording device  119 . The storage means specifying means  701  sets log accuracy classifications comprised of two classifications of, for example, a log accuracy from above 0% to less than 50% and a log accuracy from above 50% to below 100%, and stores log information corresponding to the respective log accuracy classifications in the storage means different every log accuracy classifications. Thus, the log information can be recorded every accuracy classifications. The log information recorded every log accuracy classifications are transmitted to the log delivering means  120  according to the log accuracy designation information  124  of the log delivery device as the log information  123  set according to the accuracy. Thus, when a request to provide or offer the by-accuracy log information having the accuracy from over 50% to under 100% is made from the corresponding external log acquiring means, for example, the log acquiring means is capable of obtaining by-accuracy log information corresponding to a desired log accuracy classification according to the operation of the log delivering device. 
   According to the log accumulation controller of the present embodiment described in  FIG. 7  as mentioned above, the log information transmitted from at least two in-home devices are classified according to accuracy. The log information related to the corresponding accuracy classification can be notified to the corresponding log acquiring means according to the by-accuracy log information acquisition request of the log acquiring means. 
   Incidentally, while the above-described present embodiment has adopted the configuration wherein the log information set by accuracy are recorded in the different storage means in  FIG. 7 , for example, a configuration may be adopted in which the log information are respectively stored in different areas of a single storage device. No particular limitation is imposed to a method of recording the log information set by accuracy. Further, while the present embodiment has adopted the configuration wherein the by-accuracy log information are classified and recorded upon reception of the log information, a configuration may be used wherein log information is recorded together with log accuracy information and log information corresponding to an accuracy classification designated upon its transmission is retrieved and transmitted. No particular limitation is imposed on a method of classifying log information according to accuracy. While the present embodiment has adopted the configuration wherein the corresponding log is always recorded in the corresponding storage means, for example, a configuration may also be used wherein, for example, an upper limit capacity of a log to be acquired is provided and old log information is deleted when it is desired to store log information greater than the capacity. A method of managing the acquired log information is not defined in particular. 
   Further, the present embodiment has adopted the configuration wherein the log acquiring means is capable of acquiring the log accuracy classification of the log information managed by the log recording device, and the log accuracy designation information is notified in accordance with the log accuracy classification. However, a configuration may also be adopted wherein arbitrary log accuracy designation information is notified and the optimum log accuracy classification is determined by the log recording device. In the present configuration as well, the log accuracy classification determined by the log recording device may be notified to the corresponding log acquiring device. No particular limitation is imposed on a method of formatting and notifying log accuracy designation information and a method of determining and notifying by-accuracy log information sent as a result of log accuracy designation information. 
   The operation of the contents information transmitting means of the log operating unit will be explained below with reference to  FIG. 8 . In  FIG. 8 , reference numeral  801  indicates a contents information input means capable of acquiring or obtaining contents information from the outside, reference numeral  802  indicates contents information storing means capable of storing the contents information obtained by the contents information input means  801 , and reference numeral  803  indicates contents transmitting means capable of transmitting the stored contents information to the contents delivery controller. 
   According to the contents information transmitting means  129  lying within the log operating unit  104  shown in  FIG. 8 , contents information  804  automatically and/or manually generated based on the by-accuracy log information obtained by the log acquiring means  127  of the log operating unit  104  can be sent to the contents delivery controller  101  through the contents information sending means  129 . 
   The present embodiment has adopted the configuration wherein the contents information is transmitted to the contents delivery controller through the contents information transmitting means shown in  FIG. 8 . However, no particular limitation is imposed on a contents information transmitting method such as a method of sending contents information through other dedicated/general-purpose communication means, a method of storing contents information in a storage medium and sending the medium with the contents information recorded therein, etc. 
   The operation of the AV function control means of the in-home device will next be explained with reference to  FIG. 9 . In  FIG. 9 , reference numeral  901  indicates a receiving means capable of receiving contents information  111  comprising contents substantial information and contents selection information  112 . Reference numeral  902  indicates a separating means capable of separating the contents substantial information and the contents selection information from the contents information. Reference numeral  903  indicates means for reproducing the contents substantial information. Reference numeral  904  indicates a selection information processing means capable of specifying a method of reproducing the content substantial information according to the contents selection information and stored user-designated information  215 . 
     FIG. 10  is a diagram showing a configuration of contents information, and  FIG. 11  is a diagram showing a configuration of stored user-designated information. In the AV function control means shown in  FIG. 9 , the receiving means  901  is capable of obtaining the contents information having the configuration shown in  FIG. 10 . The separating means  902  separates the obtained contents information into contents substantial information  1002  and contents selection information  1003 . In addition, the contents information  1002  is notified to the reproducing means  903 , and the contents selection information  1003  is notified to the selection information processing means  904 . As an example of the contents selection information, may be mentioned, a condition description that “when the frequency of sight and hearing of a program P or a program R is three times or mare, contents information corresponding to Class A is selected, and contents information corresponding to Class B is selected except for it” (condition  1003 ), etc. In the case of this example, the selection information processing means  904  determines a method of reproducing the contents information  1002  from the stored user-designated information  1101  and the contents selection information  1003 . While the contents selection information is information shared between the respectively in-home devices, the stored user-designated information has inherent information corresponding to user operations every in-home devices, and the contents substantial information reproduced as a result can be changed according to each in-home device. When stored user-designated information of a given in-home device, for example is of the information shown in  FIG. 11 , the selection information processing means  904  instructs the reproducing means  903  to reproduce contents information  1005  corresponding to Class A, based on the condition  1003  and the stored user-designated information shown in  FIG. 11 . Thus, the reproducing means  903  reproduces common contents information  1004  and the contents information  1005  corresponding to Class A. 
   In the present embodiment as described above, the method of reproducing the common contents information and the contents information set according to the class has used the configuration wherein the contents information set according to the class is reproduced after the reproduction of the common contents information. However, it may adopt, for example, a configuration wherein common contents information is set as motion-picture information, contents information set according to the class is set as voice information, and the common contents information and the contents information set according to the class are simultaneously reproduced, a configuration wherein a plurality of common contents information and a plurality of by-class contents information belonging to the same class are provided, etc. No particular limitation is imposed on the configuration of contents information and its reproducing method. 
   Further, the present embodiment has adopted the configuration having the correspondence between the specific condition and the reproduced class as the contents selection information. However, for example, a configuration may be adopted wherein a selection condition corresponding to user-designated information is provided as contents selection information, and contents information related to the corresponding class is selected when a user-designated information condition lying within contents selection information and stored user-designated information included in each in-home device coincide with each other. No particular limitation is imposed on a method of selecting the contents selection information and a method of describing it. 
   Furthermore, the present embodiment has adopted the configuration herein the user-designated information acquired form the user operation is processed into information indicative of the frequency of sight and hearing set according to each program and held as the stored user-designated information. However, no particular limitation is imposed on the format and contents of the held information. Further, a configuration may be adopted wherein user-designated information is stored as it is without its processing, or a configuration may be adopted wherein user-designated information is stored without its processing and necessary processing is effected thereon upon selection of contents information set according to the class corresponding to contents selection information. No particular limitation is imposed on stored user-designated information, and the presence and absence of processing of the user-designated information and the timing provided to process the user-designated information. 
   According to the in-home devices each having the AV function control means of the present embodiment described in  FIG. 9  as described above, the contents information reproducing method corresponding to the user-designated information stored in each in-home device can be selected and changed, and the delivery and reproduction of the contents corresponding to individual users who make use of the in-home devices respectively, can be carried out. 
   The operation of the log acquiring system comprising the above-described in-home devices, log accumulation controller, log operating unit, and contents delivery controller will next be explained with reference to  FIG. 1 . In  FIG. 1 , each of the in-home devices  113 ,  114  and  115  has the AV function control means  201  and is capable of reproducing contents information and reproducing/recording it. User-designated information comprised of operations such as the selection of the contents information and the reproduction and recording thereof is transmitted to the log accumulation controller  103  as log information according to each individual log accuracy set by users. The log accumulation controller  103  records the log information as by-accuracy log information every at least two accuracy classifications corresponding to log accuracy classifications on the basis of log information/log accuracy information sent from at least two in-home devices. The log acquiring means  127  and  130  of the log operating unit  104  are respectively capable of specifying log accuracies and acquiring desired log information from the log accumulation controller. Further, the log operating unit  104  is capable of automatically or manually creating contents information from at least one by-accuracy log information acquired, and sending the contents information to the contents delivery controller  101  through the contents information transmitting means  129  and  132 . The contents delivery controller  101  manages the contents information by use of the contents managing means  106  and delivers it to each of the in-home devices  113 ,  114  and  115  through the use of the delivery means  105 . The in-home devices  113 ,  114  and  115  are capable of selectively reproducing the received contents information according to stored user-designated information and contents selection information included in contents information. 
   According to the present embodiment, the user is able to set the accuracy of transmitted log information through the use of the in-home device upon sending and disclosure of the user-designated information produced based on the user operation obtainable in each in-home device to the external means such as the log accumulation controller. 
   According to the present embodiment, the log accumulation controller is capable of arranging the various log informations corresponding to the log accuracy settings of the users different every in-home devices according to the accuracy classifications and storing them. Further, the log accumulation controller is capable of offering desired by-accuracy log information corresponding to the log accuracy designation of the log operating unit to the log operating unit. Thus, log information exceeding a necessary log accuracy is not obtained at the log operating unit, and hence the efficiency of operation of the log information is improved. Further, upon creation of the contents information by the log operating unit, the log operating unit is capable of creating and sending contents information including contents information set every user segments based on the by-accuracy log information. 
   The contents information created by the log operating unit is sent to the contents delivery controller. The contents delivery controller acquires and manages the contents information and delivers the same to each of the in-home devices. It is thus possible to make a change in contents information according to each user segment and hence improve the operating efficiency of the contents information. Further, the user is able to acquire desired contents information. 
   Incidentally, while the present embodiment has adopted the configuration wherein the contents information sent from the log operating unit includes information about the selection of the contents information, a configuration may also be adopted wherein contents information with no contents selection information is transmitted. No particular limitation is imposed on the format and contents of the contents information sent to the contents delivery controller. 
   In the present embodiment as well, the contents delivery controller delivers the contents sent from the log operating unit. However, the delivery of other contents information or the delivery of the contents information and other contents information sent from the log operating unit in mixed form is also made feasible. No particular limitation is imposed on the delivery origin of the contents information or the contents and delivery path of the contents information. 
   While the present embodiment has adopted the configuration wherein the log operating unit has the log acquiring devices and the contents information transmitting means, a configuration may be adopted wherein the log operating unit has only the log acquiring devices, or a configuration may also be adopted which is used as another sending method for recording the acquisition of by-accuracy log information in, for example, a storage medium and mailing it, and wherein the log operating unit has only the contents information sending means. The configuration of the log operating unit is not limited to the configuration of the present embodiment. 
   While the contents delivery controller is configured so as to deliver the contents sent from the log operating unit in the present embodiment, the delivery of contents information created by one other than the operating unit is allowed. No particular limitation is imposed on the method for creating the contents to be delivered and its configuration. 
   While the log accumulation controller according to the present embodiment is configured so as to manage the log information according to log accuracy classification, a configuration or the like may be adopted wherein log information are recorded and managed according to log accuracy information. No particular limitation is imposed on the method for classifying and managing the log information. 
   Another embodiment of the present invention will be explained below with reference to  FIGS. 4 and 5 .  FIG. 4  is a function block diagram showing a configuration of an in-home device. In  FIG. 4 , reference numeral  403  indicates a user-designated information accuracy setting means which performs the setting of the accuracy of log information by a user, reference numeral  402  indicates a user-designated information notification control means for performing switching control on the user-designated information notifying means  401  according to log accuracy information, reference numeral  401  indicates a user-designated information notifying means capable of performing switching between an output indicative of or corresponding to user-designated information and the output of a pseudo information generating means  404  and outputting the result of switching control as log information, and reference numeral  404  indicates the pseudo information generating means capable of generating pseudo user-designated information. 
   The pseudo information generating means  404  generates user-designated information and pseudo user-designated information indicative of information about a pseudo pattern. As an example of a method for generating them, may be used, for example, a method of cutting out log information transmitted in the past every predetermined periods at random and connecting then to thereby generate pseudo user-designated information. 
   The operation of the in-home device according to the present embodiment will be explained below with reference to  FIG. 5 . As to user-designated information  209 , accuracy setting information  405  is notified to the user-designated information notification control means  402  according to an accuracy setting set by a user through the user-designated information accuracy setting means  403 . The user-designated information notification control means  402  generates notice control information  406  having the ratio between “H” and “L” corresponding to accuracy. When the accuracy setting information is given as an accuracy of 40%, for example, the user-designated information notification control means  402  generates notice control information in which the ratio of “H” to “L” is given as 2:3. While the period thereof is arbitrary, it is set as 30 minutes in the present embodiment. According to the present notice control information  406 , the user-designated information notifying means  401  outputs user-designated information during an “H” period, and outputs pseudo user-designated information as log information during an “L” period. Thus, some kind of log information is generated at all times, and user-designated information based on an actual user operation can be generated as log information containing only 40% of its entirety. According to the in-home device of the present embodiment, it becomes difficult to make a distinction between the user-designated information and pseudo user-designated information contained in the log information. Thus, user&#39;s privacy protection against the log information can be enhanced. 
   Incidentally, the present embodiment has adopted the configuration wherein the past log information is utilized as the method of generating the pseudo user-designated information. However, no particular limitation is imposed on the method of generating the pseudo user-designated information.
