Description
Technical field
The present invention relates to electronic equipment and control method thereof, particularly relate to the attribute information attached by the content received stored and also with the electronic equipment that can communicate between the exterior storage medium of attribute information storage and control method thereof.
Background technology
In recent years, broadcast technology obtains to be applied more and more widely, and people likely listen under circumstances or watch the content be broadcasted.Such as, broadcast listening when user drives a car through being everlasting or does housework.Now, user has likely heard a first melody oneself be delithted with in the broadcast, but does not hear the name of this first melody.In addition, user also can watch television broadcasting at home or in automobile.Now, user also may miss or not see the name of one section of interesting television program clearly.And in the above case, even if user does not hear or seen the name of melody or television program clearly, also probably not free or condition is recorded.Specifically, such as user has heard a first melody oneself be delithted with when driving a car, from security standpoint, this user can not take out paper pen to record the attribute informations such as song name.
Therefore, if user is after listening to or watching broadcast, it is desirable to obtain (such as entity is bought or downloaded and buys) content of oneself liking, then very possible because information is not enough this content of None-identified, result can only abandon oneself buying behavior.Like this, not only become the sorry of user, also loss is economically caused to the right owner of broadcast operator and broadcasted content.
In order to avoid this situation, broadcast operator has carried out various service, helps user to identify the content be broadcasted.Such as, broadcast operator provides contents list to user, if user knows concrete broadcast operator title and the airtime of content, then the broadcast lists that can provide by searching this broadcast operator obtains the attribute information of this content.In addition, such as additionally provide semi-match service, that is: user can issue operator a part for the content be broadcasted (such as melody), operator, by analyzing and mating, provides the attribute information (such as song name, artist name, album name, kind etc.) of this content to user.
But all there is self problem in above service.Such as, when providing contents list, user may not know concrete operator name, or does not know the concrete airtime, and result cannot obtain the attribute information of the content of hope.In addition, in semi-match service, likely make a mistake coupling, particularly when such as good as the melody tonequality of the content be broadcasted.
For the problems referred to above, patent documentation 1 (US2008/0188209A1) proposes following methods.That is, in patent documentation 1, broadcast operator is except broadcasted content, and also broadcast for identifying the attribute information additional to this content, user can receive this attribute information and store as " label (tag) ".Such as, when the content be broadcasted is melody, the attribute informations such as the song name of this melody, artist name, album name, kind are such as broadcasted by broadcast operator together with this melody, and user can receive these attribute informations and get off as tag storage.Afterwards, user can communicate with media resource Distributor, obtains sample or the content itself of content corresponding to (such as buying) according to this label.
Specifically, Patent Document 1 discloses a kind of receiving system (annex), receive by the content of operator broadcast and the attribute information relevant with this content, and pass through user's manual operation or automatically this attribute information be stored in the memory space of this receiving system as " label ".Such as, enumerated in patent documentation 1 set up the method that XML catalogue carrys out storage tags in the label file of the memory space of receiving system.
In addition, when this receiving system is connected with media player, this receiving system can send instruction thus sets up in this media player or open a label file, more than one label write this file or cut out this file.Such as, in patent documentation 1, be used for the size of the residual capacity of storage tags according to the size of the XML catalogue in the label file of the memory space of receiving system and media player, judge that can media player store this XML catalogue (that is, store this label).Only when judged result be can, by above instruction, this XML catalogue is stored to media player, namely in media player, stores this label.
In patent documentation 1, the process by this receiving system reception attribute information relevant with the content be broadcasted and as tag storage is specifically carried out (Figure 12 see patent documentation 1) according to following flow process.
First, in step 1204, judge whether this receiving system is connected with media player.If connected, then advance to step 1206, if do not connected, then advance to step 1208.
In step 1206, according to the method described above, each tag storage being used in the storage medium of storage tags to media player that the memory space of this receiving system is stored, and this label is deleted from the memory space of this receiving system.Afterwards, step 1208 is advanced to.
In step 1208, receive the content be broadcasted, obtain the attribute information be broadcasted together with this content simultaneously, and this attribute information is stored in the buffer of this receiving system.Afterwards, step 1210 is advanced to.
In step 1210, automatically determine whether the attribute information in buffer is got off (carrying out tag operational) as tag storage according to user operation or this receiving system.If do not carry out tag operational, then return step 1208.If carry out tag operational, then advance to step 1212.
In step 1212, detect this receiving system and whether be still connected with media player.If connected, then advance to step 1214, if do not connected, then advance to step 1216.
In step 1214, this receiving system to the storage medium storage tags for storage tags of media player, and waits for next broadcasted content.
In step 1216, whether the memory space detecting this receiving system has enough residual capacities to store this label.If no, then point out user to connect media player, if had, then the memory space to this receiving system stores this label, and waits for next broadcasted content.
In above-mentioned handling process, likely there is the situation for the residual capacity deficiency of the storage medium of storage tags in media player.Namely, in step 1206, if the size of each label that the memory space that the residual capacity of the storage medium for storage tags in media player is less than this receiving system stores, then all labels in the memory space of receiving system all cannot be stored in media player.Now, part or all label that the memory space of this receiving system stores still is retained in receiving system, and is not transferred to media player.Particularly, when this media player is the iPod (registered trade mark) etc. of apple (apple) company, if the capacity of all labels (attribute information) that the memory space being less than receiving system for the residual capacity of storage tags (attribute information) in this media player stores, according to existing specification, the whole labels (attribute information) stored in receiving system are not transferred in media player, and all remain in the memory space of receiving system.And, in step 1214, if the residual capacity of the storage medium for storage tags of media player is less than the size of the label that will store, then cannot to media player storage tags, even if therefore this receiving system is connected with media player, also to the memory space storage tags of this receiving system.In addition, when the residual capacity for the storage medium of storage tags and the memory space of this receiving system of media player is all not enough, user is sent to the information of " lack of memory capacity ".
The above-mentioned handling process existing problems of patent documentation 1.Such as, we it is contemplated that following situation: user is having carried out tag operational by during broadcast audience melody A, now this receiving system is not connected the residual capacity deficiency (step 1214) for the storage medium of storage tags in (step 1216) or the media player that connects with media player, and the memory space therefore to this receiving system stores this label.After this, this receiving system is connected with media player, but due to the size of whole labels that the memory space being less than this receiving system for the residual capacity of the storage medium of storage tags in media player stores, so this label may still be retained in this receiving system.Particularly when this media player is the iPod (registered trade mark) etc. of apple (apple) company, as mentioned above, the whole labels (attribute information) now stored in this receiving system all former state are retained in this receiving system and are not transferred to media player, so this label is still retained in (step S1206) in the memory space of this receiving system certainly.Then, user again by broadcast audience melody A and carried out tag operational (such as can expect this user listen to specifically melody A different piece or have forgotten last time tag operational and by multiple situations such as different user uses).Now, because media player is connected with this receiving system, so directly by this tag storage (step 1214) in media player.Like this, at the memory space of this receiving system and media player in the storage medium of storage tags, all store the label of identical melody A.
In this case, in the memory space of receiving system, store the label repeated with media player, this obviously becomes the waste of the memory space to this receiving system.Such as, when this receiving system is on-vehicle navigation apparatus, the memory space of storage tags generally adopts EEPROM (EEPROM (Electrically Erasable Programmable Read Only Memo)).The size of guider EEPROM is originally 10kB, in order to storage tags, such as, this EEPROM is increased to 64kB, can store about 50 labels thus.If the EEPROM of guider is full, then cannot storage tags again, and from fail safe angularly, user cannot identification or delete the label stored in this EEPROM.Now, if user by broadcast audience to the melody liked, then cannot store the label of this melody in guider, cannot identify this melody and buy afterwards.Namely, the above-mentioned handling process of patent documentation 1 may store the label repeated with media player in receiving system, this becomes the waste of the memory space to receiving system, and probably causes the economic loss of the right owner of the sorry of user and broadcast operator and broadcasted content.
Particularly when this media player is the iPod (registered trade mark) etc. of apple (apple) company, as mentioned above, if the capacity of all labels (attribute information) that the memory space being less than receiving system for the residual capacity of storage tags (attribute information) in this media player stores, according to existing specification, the whole labels (attribute information) stored in receiving system are not transferred in media player, and all remain in the memory space of receiving system.In this case, if store the label identical with the label that media player stores in the memory space of receiving system, then not only there are the problems referred to above, and the total label capacity to store due to the memory space of receiving system increases, also probably cause this total label capacity to be greater than residual capacity for storage tags in media player, finally all labels (attribute information) in receiving system occur all cannot be transferred to the significant problem of media player.That is, in this case, in receiving system, a unnecessary label probably causes whole label all cannot be transferred to the situation of media player.Obviously, this can buy broadcasted content by media player according to label to user and cause huge obstacle, causes the heavy economic losses of the right owner of the great sorry of user and broadcast operator and broadcasted content.And, if store the label repeated with media player in the memory space of receiving system, so when afterwards receiving system being connected with media player, if enough store this label for the residual capacity of the storage medium of storage tags in media player, then this label stored in the memory space of receiving system is transferred in media player.Now, in media player, store two identical labels.This not only can cause the waste for the storage medium of storage tags in media player, and, when user buys related content by media player according to label, probably cause the repeat buying of user, thus unnecessary economic loss is produced to user, and make the reputation of broadcast operator and receiving system manufacturer impaired.
