The terms first, second, A, B, etc., may be used to describe various components, but the components are not limited by the terms, but may be used to distinguish one component from another . For example, without departing from the scope of the following description, the first component may be referred to as a second component, and similarly, the second component may also be referred to as a first component. And / or < / RTI > includes any combination of a plurality of related listed items or any of a plurality of related listed items.

Before describing the drawings in detail, it is to be clarified that the division of constituent parts in this specification is merely a division by main functions of each constituent part. That is, two or more constituent parts to be described below may be combined into one constituent part, or one constituent part may be divided into two or more functions according to functions that are more subdivided. In addition, each of the constituent units described below may additionally perform some or all of the functions of other constituent units in addition to the main functions of the constituent units themselves, and that some of the main functions, And may be carried out in a dedicated manner.

Also, in performing a method or an operation method, each of the processes constituting the above method may occur in a different order than that described in the context without explicitly specifying a specific order in the context. That is, each process may occur in the same order as described, may be performed substantially concurrently, or may be performed in the opposite order.

The technique described below relates to a method of streaming contents to a contents reproducing apparatus or a method of providing contents to a contents reproducing apparatus. Content refers to digital contents such as a sound source, a voice, a moving picture, a photograph, and the like. In the techniques described below, the content reproduction apparatus includes a computer apparatus such as a smart phone, a tablet, a PC, and the like. Furthermore, the content reproduction apparatus may be a dedicated apparatus for reproducing the content. If the content reproduction apparatus is a smart phone, the content will be reproduced basically through an application for receiving the content streaming service. In the case of a dedicated device for content playback, a program for receiving a content streaming service may be an embedded device.

The technique described below uses a physical medium that plays a similar role as a conventional compact disc (CD) or the like. Here, the physical medium means a recording medium storing information. The physical medium includes a short range wireless communication module for transmitting the information held by the physical medium to the content reproduction apparatus. The short-range wireless communication module may be at least one of an NFC communication module, an RFID communication module, a Bluetooth communication module, a Wi-Fi communication module, or an ultra-high-speed proximity communication module.

The ultra high-speed proximity communication means a next-generation short-range communication technology in which data is instantly transmitted at a giga level while wireless power is supplied to a medium storing a large amount of data in a reader (a content reproduction device) receiving data. This is the case, for example, in the 60 GHz ultra-fast proximity communication technology field.

The content reproduction apparatus must also include the same local wireless communication module as the physical medium in order to receive the information. Hereinafter, a physical medium is simply referred to as a medium. For example, the medium may be in the form of a card containing an NFC module. Of course, media can have various physical forms rather than card form. The medium includes information and the like for streaming the content. Specific information stored by the medium will be described later.

Hereinafter, a content streaming method using near field wireless communication and a content providing method using near field wireless communication will be described in detail with reference to the drawings.

1 is an example of a block diagram illustrating the configuration of a content streaming system 100. As shown in FIG.

The user can purchase the medium 110 through an offline store or an online marketplace. In FIG. 1, the contents reproducing apparatus 120 shows an example of a dedicated apparatus for reproducing contents. When the user brings the medium 110 close to the content reproduction apparatus 120, the content reproduction apparatus 120 receives the information included in the medium 110. [ It is assumed that the content reproduction apparatus 120 can perform short-range wireless communication such as an NFC card. In the content reproduction apparatus 120, the medium contact area 121 is separately displayed. In general, it is sufficient to temporarily connect the NFC card to a dedicated reader or a smartphone. However, since the content must be streamed in FIG. 1, the medium 110 needs to be connected to the content reproduction apparatus 120 for a relatively long time.

FIG. 1 shows an example in which the medium 110 is close to the content reproduction apparatus 120. FIG. Furthermore, the user can raise the medium 110 above the media contact area 121 of the content reproduction apparatus 120 and stream the content. A short range wireless communication module (e.g., an NFC antenna or the like) may be located at the lower end of the medium contact area 121. In FIG. 1, the medium 110 stores content to be streamed or transmitted.

The content reproduction apparatus 120 measures the intensity of a signal transmitted from the medium 110 or the error rate of data transmitted from the medium 110. FIG. 1 shows an example of measuring the strength of a signal on the basis of a received signal strength indicator (RSSI), and an example of measuring a data error rate with a bit error ratio (BER).

As will be described later, the content reproducing apparatus 120 may receive the stream from the medium 110, or receive and store the same at a time when the signal strength is equal to or greater than the reference value or the rate of data is less than the reference value. In the latter case, the content reproduction apparatus 120 may store all of the content and then reproduce the stored content according to the request of the user.

2 is an example of a procedure flow diagram for a content streaming method 200 using short-range wireless communication. 2 is an example in which the content reproduction apparatus 120 streams the content from the medium 110. FIG.

The content reproduction apparatus 120 accesses the medium 110 through short-range wireless communication (211). The content reproduction apparatus 120 requests the content 110 to stream the content (221). The content reproduction apparatus 120 starts to stream the content from the medium 110 (222).

When the streaming starts, the content reproducing apparatus 120 measures the intensity of a signal transmitted from the medium 110 or the error rate of data transmitted from the medium 110 from a predetermined reference time point or at the start of streaming (231). The content reproduction apparatus 120 can continuously measure the intensity or the error rate of the signal for a predetermined time (e.g., one second). The content reproduction apparatus 120 may measure the intensity or error rate of the signal at a predetermined number of times (for example, five times) for a predetermined time.

Generally, the strength of a signal can be known through received signal strength indicator (RSSI). The error rate may be measured using a retransmission rate of a data packet received from the medium 110 or an error check bit (CRC) included in the data received from the medium 110. Generally, the error rate can be known based on a bit error ratio (BER). For convenience of explanation, it is assumed that the signal strength is RSSI and the data error rate is BER.

The content reproduction apparatus 120 may determine that the data is transmitted stably when the RSSI of the signal is equal to or greater than the reference value or the error rate (BER) is equal to or less than the reference value. For example, this may correspond to a state in which the medium 110 does not move in contact with the medium connection region 121 of the content reproduction apparatus 120. [ If the RSSI is equal to or greater than the reference value or the error rate BER is less than or equal to the reference value, the content reproduction apparatus 120 transmits a continuous streaming request to the media 110 (241) Streaming can be received continuously (242). The process of transferring the continuous streaming request (241) may be omitted. That is, when the content reproduction apparatus 120 does not transmit a separate message, it may automatically receive continuous streaming from the medium 110 without exchanging an ACK message.

Generally, when a certain data packet is transmitted through short-range wireless communication, a subject receiving the data packet sends a message to the transmitting side that the information is properly received. However, when the medium 110 such as an NFC card is positioned on the content playback apparatus 120 without moving, the medium 110 and the content playback apparatus 120 may exchange the ACK message and transmit the received data, . Accordingly, in a state where the reliability of data transmission and reception is ensured, the content reproduction apparatus 120 continuously receives the streaming without exchanging an ACK message with the medium 110.

If the content is streamed without ACK message exchange, it may be streamed without exchanging an ACK message only for a certain period of time (e.g., 1 second). In this case, it is possible to measure the intensity of the signal transmitted again by the content reproducing apparatus 120 or the error rate of the data transmitted by the medium 110 at a predetermined time (251). The content reproduction apparatus 120 transmits (261) a continuous streaming request to the medium 110 when the RSSI of the signal is equal to or greater than the reference value or the error rate (BER) is equal to or less than the reference value, Lt; RTI ID = 0.0 > 110 < / RTI >

After a certain period of time has elapsed since the start of the continuous streaming, the content reproducing apparatus 120 can measure the intensity of the signal to be transmitted again or the error rate of the data transmitted by the medium 110 (271). If the signal strength RSSI is less than the reference value or the error rate BER exceeds the reference value, the content playback apparatus 120 may send a streaming suspension request to the media 110 (281). The streaming of content is then discontinued (282). Of course, without the process of transmitting the streaming stop request 281, the content reproduction apparatus 120 may stop receiving the content. The content streaming will be terminated while the medium 110 is detached from the media contact area 121 of the content reproduction apparatus 120 or is distanced from a communication impossible distance.

A reference value related to the RSSI is referred to as a first reference value, and a reference value associated with the error rate (BER) is referred to as a second reference value. In this case, the first reference value may be the maximum value of the signal strength, and the second reference value may be the minimum value of the error rate. Of course, each reference value may be somewhat different.

When the content reproducing apparatus 120 measures the RSSI or the BER of a signal continuously or a predetermined number of times for a predetermined period of time, the value to be compared with the reference value may be an average value of the RSSI for a predetermined time, And may be an average value of BER.

The content reproduction apparatus continuously transmits the ACK message without exchanging the ACK message with the medium when the signal strength RSSI maintains the maximum value for the reference time or when the error rate (BER) of the data transmitted by the medium maintains the minimum value for the reference time. Or may request streaming.

3 is an example of a procedure flow chart for a content providing method 300 using short-range wireless communication. FIG. 2 shows an example in which the content reproduction apparatus 120 streams content from the medium 110, and FIG. 3 shows an example in which the content reproduction apparatus 120 receives and stores all the content stored in the medium 110.

3 (a) shows an example in which the RSSI value is equal to or greater than the reference value or the BER is equal to or smaller than the reference value. The content reproduction apparatus 120 accesses the medium 110 through short-range wireless communication (311). The content reproduction apparatus 120 requests the delivery of the content to the medium 110 (321). The content reproduction apparatus 120 starts to receive the content from the medium 110 (322).

The content reproduction apparatus 120 measures the intensity of a signal transmitted from the medium 110 or the error rate of data transmitted from the medium 110 from a predetermined reference time point or a reception start time after receiving the content (331). The content reproduction apparatus 120 can continuously measure the intensity or the error rate of the signal for a predetermined time. The content reproducing apparatus 120 may measure the intensity or the error rate of the signal at a predetermined number of times for a predetermined time.

The content reproduction apparatus 120 may determine that the data is transmitted stably when the RSSI of the signal is equal to or greater than the reference value or the error rate (BER) is equal to or less than the reference value. If the RSSI is equal to or greater than the reference value or the error rate (BER) is less than or equal to the reference value, the content reproduction apparatus 120 requests the remaining content on the medium 110 (341). The content reproduction apparatus 120 can receive all the remaining contents without exchanging the ACK message with the medium 110 (342). Of course, the content reproduction apparatus 120 may automatically receive all the remaining content without exchanging an ACK message with the medium 110 without requesting the remaining contents (step 341).

The content reproduction apparatus 120 stores all the received content in its own storage medium (351). Thereafter, the content reproduction apparatus 120 can reproduce the content according to the user's reproduction command (361).

3 (b) shows an example in which the RSSI value is less than the reference value or the BER is greater than the reference value. The content reproduction apparatus 120 accesses the medium 110 through short-range wireless communication (311). The content reproduction apparatus 120 requests the delivery of the content to the medium 110 (321). The content reproduction apparatus 120 starts to receive the content from the medium 110 (322).

After receiving the content, the content reproducing apparatus 120 measures the intensity of the signal transmitted from the medium 110 or the error rate of the data transmitted from the medium 110 from a predetermined reference time point or at the start of streaming (331).

The content reproduction apparatus 120 may transmit the measurement result to the medium 110 when the signal strength RSSI is less than the reference value or when the error rate BER exceeds the reference value 371. In this case, the content reproduction apparatus 120 does not receive the content (372). Of course, the content reproduction apparatus 120 may not transmit a separate streaming stop request to the medium 110, and may not receive the content.

4 is another example of a procedure flow chart for a content providing method 400 using short-range wireless communication. 4 is an example in which the content playback apparatus 120 receives and stores all the content stored by the medium 110 as shown in FIG. However, in FIG. 4, a signal strength (RSSI) or an error rate (BER) is measured using a test packet.

4A is an example of a case where the RSSI value is equal to or greater than the reference value or the BER is equal to or smaller than the reference value. The content reproduction apparatus 120 accesses the medium 110 through short-range wireless communication (411). The content reproduction apparatus 120 requests the test packet to the medium 110 (421). The content reproduction apparatus 120 receives the test packet from the medium 110 (422).

After receiving the test packet, the content reproducing apparatus 120 measures the intensity of the signal transmitted from the medium 110 or the error rate of the data transmitted from the medium 110 from the reference time point or the receiving time of the test packet (431) . The content reproduction apparatus 120 can continuously measure the intensity or the error rate of the signal for a predetermined time. The content reproducing apparatus 120 may measure the intensity or the error rate of the signal at a predetermined number of times for a predetermined time.

The content reproduction apparatus 120 may determine that the data is transmitted stably when the RSSI of the signal is equal to or greater than the reference value or the error rate (BER) is equal to or less than the reference value. If the signal strength RSSI is equal to or higher than the reference value or the error rate BER is lower than the reference value, the content reproduction apparatus 120 requests the medium 110 to transmit the content (441). The content reproduction apparatus 120 can receive all the contents without exchanging the ACK message with the medium 110 (442). Of course, the content playback apparatus 120 may automatically receive all the remaining content without exchanging the ACK message with the medium 110 without requesting the content 441.

The content reproduction apparatus 120 stores all the received content in its own storage medium (451). Thereafter, the content reproduction apparatus 120 can reproduce the content according to the reproduction instruction of the user (461).

4 (b) shows an example in which the RSSI value is less than the reference value or the BER is greater than the reference value. The content reproduction apparatus 120 accesses the medium 110 through short-range wireless communication (411). The content reproduction apparatus 120 requests the test packet to the medium 110 (421). The content reproduction apparatus 120 receives the test packet from the medium 110 (422).

After receiving the test packet, the content reproducing apparatus 120 measures the intensity of the signal transmitted from the medium 110 or the error rate of the data transmitted from the medium 110 from the reference time point or the receiving time of the test packet (431) .

The content reproduction apparatus 120 may transmit the measurement result to the medium 110 when the signal strength RSSI is less than the reference value or when the error rate BER exceeds the reference value.

In this case, the content reproduction apparatus 120 may not receive the content. Further, as shown in FIG. 4 (b), the content may be received using the conventional ACK message exchange method (444). Of course, it is assumed that the medium 110 is adjacent to the content reproduction apparatus 120. [ Thereafter, the content reproduction apparatus 120 stores the received content in its own storage medium (451). Thereafter, the content reproduction apparatus 120 can reproduce the content according to the reproduction instruction of the user (461).

4, the content reproduction apparatus 120 measures the intensity of the signal or the data error rate from the medium 110 using the test packet. Wherein the test packet may use a packet having predefined data. In this case, the content reproduction apparatus 120 can measure the data error rate only by determining whether or not the previously defined data contents are delivered as is without calculating the packet retransmission rate or the like.

In addition, the test packet can partially use the content data stored in the medium 110. That is, FIG. 3 may be considered as an example of using a part of content data as a test packet. In FIG. 3, the process in which the medium 110 delivers the initial content 322 may correspond to an example of delivering a test packet.

Fig. 5 is an example showing the configuration of the medium 110. Fig. FIG. 5 exemplarily shows an NFC card type medium. Media 110 of FIG. 5 illustrates media 110 of FIG. 1 by way of example.

The antenna 111 performs RF communication with the content reproduction apparatus to transmit information stored or generated by the medium to the content reproduction apparatus. The control chip 112 selects information stored in the medium 110 according to an external RF signal, or processes the stored information to select information. The control chip 112 analyzes the command of the RF signal received from the antenna 111 and generates control information for generating the information in response to the RF signal and transmitting the generated information to the antenna 111.

The medium 110 stores certain information in the memory 113. [ Although the control chip 112 and the memory 113 are shown as separate blocks in FIG. 5, they may actually have a single chip form. In addition, the antenna 111, the control chip 112, and the memory 113 may all have a single chip form.

In Fig. 5, the memory 113 stores test data and contents. (1) When separate test data for measuring the signal strength or data error rate is used as described in FIG. 4, the memory 113 may store test data. (2) content refers to the source data for streaming or delivering to the content reproduction apparatus 120. For example, the content may be music data, video data, or the like. Further, the memory 113 may store additional information not shown in FIG.

The CPU 510 controls the content reproduction apparatus 500 with a main processor, and processes signals to be exchanged with the medium 110. The memory 520 may be used as a buffer in the operation process of the CPU 510. [ Further, the memory 520 may store the content received from the medium 110. Of course, in addition to the memory 520, a content may be stored using a separate storage medium. The storage medium includes various media such as a flash memory, a solid-state drive (SSD), a hard disk, and the like.

The short-range communication module 530 means a module for performing short-range communication with the medium 110. The short range communication module 530 includes an antenna, a control chip, and the like.

The display device 540 can basically output the content. For example, if the content is a video-like content, the display device 540 outputs the video. The display device 540 may also output the content information (metadata). For example, if the content is a sound source, the content information may include information about the file name, the name of the sound source, the name of the sound source, the name of the album, the composer of the sound source, the lyrics of the sound source, Or the like. Also, the display device 120 may output an interface screen for the user.

The speaker 550 outputs sound included in the content. For example, if the content is a sound source, the sound source is output.

The interface device 560 receives a control command for the content reproduction apparatus 500 from the user. For example, the user may use the interface device 560 to establish a communication connection between the medium 110 and the content reproduction apparatus 500, or to stream or receive a specific content from the medium 110. The interface device 560 is meant to include various devices such as physical buttons, touch panels, keyboards, keypads, and the like.

On the other hand, the user can edit the information stored in the medium 110 through the content reproducing apparatuses 120 and 500. The user can edit (delete, update, etc.) the content itself stored in the medium 110 or edit content information about the content stored in the medium. For example, the user can delete content stored on the medium 110, store new content on the medium 110, change the metadata of the content (song name, artist name, album information, etc.) have.

7 is an example of a procedure flow diagram for a method 600 of editing content or content information. The content reproduction apparatus 120 accesses the medium 110 through short-range wireless communication (611). The content reproduction apparatus 120 requests the medium 110 for the content information 621 and the medium 110 forwards the content information to the content reproduction apparatus 120 (622).

The content reproducing apparatus 120, 500 may measure the RSSI of the signal transmitted from the medium 110 or the error rate (BER) of the received data (631) as described above in the course of receiving the content information, . The following process can be performed when the RSSI is equal to or greater than the reference value or when the data error rate (BER) is equal to or less than the reference value. That is, the content information and the like can be edited when the medium 110 is placed (fixed) in the medium contact area 121 of the content reproduction apparatus 120.

The content reproduction apparatuses 120 and 500 output the received content information (641). The user confirms the content information, and inputs a target of editing and information to edit (651). The edit command includes data that the user intends to edit content or content information.

The content reproduction apparatus 120, 500 transmits the editing information to the medium 110 (661). The medium 110 updates the data stored therein based on the editing information (671). For example, the user can delete the stored content, update the stored content, store new content, and correct content information (metadata) for the stored content.

Further, the medium 110 may transmit (681) the content information requested by the content reproducing apparatus 120, 500 or automatically edited to the content reproducing apparatus 120, 500. The content reproduction apparatuses 120 and 500 can output the edited content information (691).
