Description

  The present invention relates to a chapter skip method and a seek bar method.

  Conventionally, a distribution server method is known. For example, in Japanese Patent Laid-Open No. 2013-214800, the client sequentially requests each HTTP GET request designating each HTTP URL (network location information) indicating each segment on the content file stored in the server, and the server requests the request. Accordingly, a technique is disclosed in which each segment is acquired from the content file and responds sequentially, and the client sequentially downloads each segment.

JP2013-214800A

  By the way, the conventional distribution server method has a problem that it is impossible to provide a chapter skip means or a seek bar means that constitutes a user operation unit.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a method and apparatus that can provide chapter skip means or seek bar means that constitute a user operation unit.

  In order to solve the above-described problem, in the method of the present invention, the apparatus detects a chapter skip means that forms a user's operation section on the display means, detects an operation of the chapter skip means, And a second step of dereferencing a segment corresponding to the chapter skip means.

  According to the present invention, the method and apparatus can provide a chapter skip unit or a seek bar unit that forms an operation unit of a user.

It is an example of the block diagram of the content delivery system of embodiment.

  Hereinafter, an embodiment of the present invention will be described in detail.

FIG. 1 is an example of a configuration diagram of a content distribution system according to an embodiment.
For example, the content distribution system displays the current playback position of the content 21 that is a moving image, and displays the seek bar 22 including the slider 23 that can arbitrarily specify the playback start position of the content 21 and the content 21 by user operation. A server 1 on the Internet 10 that stores the web page 20 and each segment file S obtained by subdividing the content 21, and is connected to the Internet 10 to display the web page 20 and provide the content 21 to the user The client 2 is configured.

  The devices such as the server 1 and the client 2 include a computer unit including a CPU, a ROM, a RAM, an input / output unit (touch panel unit, display unit, etc.), a communication unit (Internet communication unit, etc.), and the like.

  The web page 20 includes index information including HTTP URLs (network location information including the host name or IP address of the server 1) indicating the segment files S of the content 21 arranged in the reference order of the segment files S, and a seek bar 22 Indicates that the HTTP URLs of the index information are sequentially associated with the respective positions divided by the total number of the segment files S of the content 21, and the server 1 sends an HTTP GET request (unreferenced) specifying the HTTP URL from the client 2. ) To respond to the client 2 with the segment file S indicated by the HTTP URL.

  The index information includes each HTTP URL at the start position of each chapter into which the content 21 is divided as chapter index information, and the web page 20 includes a chapter skip button (not shown).

Processing of the content distribution system will be described.
The client 2 requests the web page 20 from the server 1, the server 1 responds to the client 2 with the web page 20 in response to the request, and the client 2 downloads the web page 20 and displays it on the display unit. The server 1 sequentially requests each HTTP GET request designating each HTTP URL after the head of the content 21 with reference to the index information, and the server 1 sends each segment file S pointed to by the HTTP URL to the client in response to the sequential request. In response to 2 in order, the client 2 sequentially downloads the segment files S and displays the content 21 to be reproduced from the top on the web page 20.

  The client 2 playing the content 21 detects the movement of the slider 23 by the user, acquires the HTTP URL of the new position of the slider 23 by referring to the index information, and refers to the index information and the subsequent HTTP URL In response to each sequential request, the server 1 sequentially responds to the client 2 with each segment file S pointed to by the HTTP URL, and the client 2 The file 21 is sequentially downloaded and the content 21 to be reproduced after the position is displayed on the web page 20.

  Further, the operation of the chapter skip button is detected, and each HTTP GET request specifying each HTTP URL after the start position of the next chapter is sequentially requested with reference to the index information, and the server 1 responds to the sequential request. Then, each segment file S pointed to by the HTTP URL is sequentially responded to the client 2, and the client 2 sequentially downloads each segment file S and displays the content 21 to be reproduced after the start position on the web page 20. .

  In the above embodiment, each segment file S starts from an I frame, but may be configured to include a plurality of GOPs in order to correspond to trick play that thins out GOP (Group of Pictures) such as fast forward playback and fast reverse playback, A GOP is a series of media data from an I frame to the previous I frame. Trick play is realized by a configuration in which the client 2 that has downloaded the segment file S supports trick play, or the client 2 makes an HTTP GET request including an HTTP URL including parameters for instructing trick play, and the server 1 supports trick play. The segment file S is generated and responded to the client 2. The server 1 responds to the client 2 after the position on the corresponding segment file S in response to an HTTP GET request including a parameter specifying the position of an arbitrary I frame on the segment file S in the HTTP URL. Also good.

  The client 2 detects an operation in which the user places a finger on the slider 23 and moves the slider 23, acquires the HTTP URL of the moved position by referring to the index information, and an HTTP GET request specifying the HTTP URL In response to the request, the server 1 responds to the client 2 with the segment file S pointed to by the HTTP URL, and the client 2 downloads the segment file S, reproduces the content 21 in a stationary state, 20, detecting that the finger is released, referring to the index information, sequentially requesting each HTTP GET request designating each HTTP URL subsequent to the HTTP URL, and the server 1 requests the sequential request In response, each segment file S pointed to by the HTTP URL is sequentially responded to the client 2, and the client 2 sequentially downloads each segment file S. Then, the content 21 to be reproduced after the position is displayed on the web page 20.

  The server 1 is preferably configured to store each segment file S having a plurality of image quality such as SD, HD, full HD, 4K, 480p, 720p, and 1080p for the content 21. The content 21 may be a homepage, blog, bulletin board, webinar, software, document such as PDF, music such as MP3, IP broadcast such as a TV program, a radio program, etc. in addition to the moving image.

  The server 1 detects that it has exceeded its processing capability, and responds to the client 2 with an HTTP URL including the host name or IP address of the mirror server 1 in response to dereference of the HTTP URL. 2 dereferences the HTTP URL in response to reception of the HTTP URL, and sequentially dereferences it after replacing all the host names or IP addresses of the subsequent HTTP URLs with the received host name or IP address, The segment files S may be downloaded sequentially from the mirror server 1.

  The server 1 may be configured to acquire each corresponding segment from the content file and sequentially respond in response to sequential dereference of each HTTP URL indicating each segment on the content file stored by itself. Each segment file S may be configured to be distributed and stored in each server 1 on the Internet 10.

  In the above description, the case where various control programs including the communication control program are stored in the ROM in advance has been described. However, the control program may be recorded on a storage medium readable by the computer unit. With such a configuration, when the program is read from the storage medium by the computer unit and the computer unit executes processing according to the read program, the same operation and effect as those of the apparatus of the above-described embodiment can be obtained.

  Here, the storage medium is a semiconductor storage medium such as RAM or ROM, a magnetic storage type storage medium such as FD or HDD, an optical reading type storage medium such as CD, DVD or BD, or a magnetic storage type / optical such as MO. Any storage medium can be used as long as it is a computer-readable storage medium regardless of electronic, magnetic, optical, or other reading methods.

  Further, the control program can be downloaded, installed and executed via a network system such as the Internet or a LAN.
