Abstract

The invention provides an electronic device and a control method thereof. The method comprises the following steps of: under a condition of judging that all attribute information stored in an attribute information storage part of the electronic device can not be transferred to an external storage medium, when an instruction for storing the additional attribute information of the currently received content into the attribute information storage part is input from an operating part, comparing the residual storage capacity of the external storage medium with the data volume of the additional attribute information; under the condition of judging that the additional attribute information can be transferred to the external storage medium, transferring the additional attribute information from an information reading part to the external storage medium through a communication part, and further judging whether the attribute information same as the additional attribute information is stored in the attribute information storage part; and under the condition of judging that the same attribute information is stored in the attribute information storage part, deleting the same attribute information from the attribute information storage part. Thus, the electronic device and the external storage medium are prevented from storing the same attribute information.

Description

technical field

[0001] The present invention relates to an electronic device and its control method, in particular to an electronic device which stores attribute information attached to content being received and communicates with an external storage medium capable of storing the attribute information and its control method. Background technique

[0002] In recent years, broadcasting technology has been more and more widely used, and it is possible for people to listen to or watch broadcasted content in various environments. For example, users often listen to the radio while driving a car or doing household chores. At this point, the user may have heard a piece of music that he likes on the radio, but he has not heard the name of the piece of music. In addition, users also watch TV broadcasts at home or in cars. At this time, the user may also miss or fail to see the name of an interesting TV broadcast program. And, in the above case, even if the user hears or sees the na...

[0049] figure 1 It is a block diagram showing the configuration of the electronic device 100 according to the first embodiment of the present invention. This electronic device 100 includes a digital broadcast receiving unit 110 , an operation unit 120 , a communication unit 130 , an attribute information storage unit 140 , a control unit 150 , and an information reading unit 160 . The specific structure and connection relationship of each part of the electronic device 100 will be described in detail below.

[0050]

[0051] The digital broadcast receiving unit 110 receives broadcast content and attribute information attached to the content. Specifically, the digital broadcast receiving unit 110 includes, for example, an antenna 111 , a tuner receiving unit 112 , a tuner digital information analysis unit 113 , and an information storage unit 114 .

[0052] Antenna 111 detects broadcasts wirelessly, such as through radio, WiFi, cellular communication network or wireless TV, sa...

[0092] image 3 It is a block diagram showing the configuration of electronic device 200 according to the second embodiment of the present invention.

[0093] Such as image 3 As shown, the electronic device 200 according to the second embodiment of the present invention differs from the electronic device 100 according to the first embodiment in that the electronic device 200 includes a notification unit 260 . Other structures of the electronic device 200 are the same as those of the electronic device 100 , and use the same reference numerals as those of the electronic device 100 , which will not be repeated here.

[0094] The notification unit 260 notifies, for example, that the attribute information attached to the content being received by the digital broadcast receiving unit 110 has been transferred from the information reading unit 160 to the external storage medium 1 . Specifically, the notification unit 260 is, for example, a speaker or a display, and notifies the use...
