FIG. 7 is a diagram illustrating a conventional streaming service using the streaming list 600 of FIG. 6.

FIG. 7A illustrates content download (content transfer) from the server 110 to the terminal 120 over time, and FIG. 7B illustrates content playback on the terminal 120 in time. It is shown according to the flow.

In the conventional streaming, since content transmission and content playback are performed at the same time, after the reproduction of the content is completed, the next content is downloaded and reproduced simultaneously.

Referring to FIGS. 7A and 7B, when the download D1 of the first content starts when t = T _D1 , the playback P1 of the first content starts when t = T _P1 .

Since the first content, the second content, the third content, and the fourth content are contents whose bit rate is equal to or less than a predetermined value or longer than the transmission request time, the first content, the second content, the third content, and the fourth content are longer. Playback P1 of the first content continues.

In the conventional streaming, even if the download D1 of the first content is completed, if the reproduction P1 of the first content is not completed, the download D2 of the second content does not start.

When the reproduction (P1) of the first content is completed, the terminal 120 transmits a transmission request message for the second content to the server 110, thereby starting when the download (D2) of the second content is t = T _D2 At the same time, playback of the second content (P2) is started when t = T _P2 .

If, when t = T, the connection state between the terminal 120 and the server 110 worsens or a problem occurs in the communication module of the terminal 120 before t2 is reproduced, P2 is completed, After the playback of the second content (P2) is completed, the download of the third content (D3) and the download of the fourth content (D4) becomes impossible, so that the playback of the third content (P3) and the playback of the fourth content (P4) ) May not be achieved.

This problem is a problem that can often occur when the terminal 120 is a mobile terminal such as a smart phone, a mobile communication terminal, and the user uses the streaming service while moving with the mobile terminal.

A streaming service according to an embodiment of the present invention, which can solve the above-described problem in the conventional streaming service, will be described with the same example with reference to FIG. 8.

8 is a diagram illustrating a case of providing a streaming service according to an embodiment of the present invention using the streaming list 600 of FIG.

FIG. 8A illustrates content download (content transfer) from the server 110 to the terminal 120 over time, and FIG. 8B illustrates content playback on the terminal 120 in time. It is shown according to the flow.

In the conventional streaming, since the content transmission and the content playback are performed at the same time, the content transmission and the content playback are completely independent in the streaming according to the embodiment of the present invention, compared to the download of the next content after the content playback is completed.

Referring to FIGS. 8A and 8B, when the download D1 of the first content starts when t = T _D1 , the playback P1 of the first content starts when t = T _P1 .

Referring to FIG. 8A, after the download D1 of the first content starts when t = T _D1 , when the download D1 of the first content is completed, the terminal 120 returns to the server 110. By sending the transfer request message of the second content, the download D2 of the second content is immediately started when t = T _D2 . Subsequently, when the download D2 of the second content is completed, the terminal 120 transmits a transfer request message of the third content to the server 110, whereby when the t = T _D3 , the download D3 of the third content is performed. Then it starts immediately. Subsequently, when the download D3 of the third content is completed, the terminal 120 transmits a request message for transmitting the fourth content to the server 110, whereby when the t = T _D4 , the download D4 of the fourth content is performed. Subsequently, all contents corresponding to all content information included in the streaming list 600 may be downloaded to the terminal 120.

Referring to FIG. 8B, after the playback of the first content _P1 starts when t = T _P1 , when the playback of the first content P1 is completed, the playback of the already downloaded second content ( P2) starts when t = T _P2 .

While the second content is being played back (P2), when t = T, when the connection state between the terminal 120 and the server 110 becomes worse or a problem occurs in the communication module of the terminal 120, the terminal 120 may not download any content from the server 110.

However, according to the embodiment of the present invention, as shown in (a) of FIG. 8, since all the content corresponding to all the content information included in the streaming list 600 is down to the terminal 120 By using the third content and the fourth content that have already been downloaded, the playback of the third content P3 and the playback of the fourth content P4 may be normally performed.

As described above, according to the present invention, when the external communication situation deteriorates (for example, the connection state between the terminal 120 and the server 110 becomes worse or a problem occurs in the communication module or the server 110 of the terminal 120). Even if it occurs, it is possible to provide a streaming service that provides a streaming service that is robust to changes in the external communication situation in which all the contents on the desired streaming list can be played on the terminal 120.

In the above description, all elements constituting the embodiments of the present invention are described as being combined or operating in combination, but the present invention is not necessarily limited to the embodiments. In other words, within the scope of the present invention, all of the components may be selectively operated in combination with one or more. In addition, although all of the components may be implemented in one independent hardware, each or all of the components may be selectively combined to perform some or all functions combined in one or a plurality of hardware.
