BACKGROUND OF THE INVENTION
The present invention relates to a technology for extracting viewing frequency of content by time in a system for distributing digital contents such as audio and moving images, and in particular, a method for extracting a portion that is repeatedly viewed in stream distribution, and system , Digest automatic generation method and system The present invention relates to a viewing location extraction program and a recording medium for the program, a digest automatic generation program, and a recording medium for the program.
[0002]
[Prior art]
In stream distribution (a method in which data is continuously transmitted while being reproduced), video and audio data are divided into frames and sent from the stream distribution apparatus to the client. During the stream reception, the client sends various control messages to the server as necessary. This control message includes a connection request message and a disconnection request message sent from the client side, a control message sent when the user plays, stops, fast forwards, rewinds, pauses the stream, and the network quality. Depending on the situation, quality control messages (band change request message, retransmission request message) that are automatically sent regardless of the user's will are roughly classified into three types.
[0003]
The present invention uses a control message (playback, stop, fast forward, rewind, pause message) sent when a user operates. The connection request message is a message for issuing a connection request to a server having content that the user wants to view, and the disconnection request message is a message for issuing a request for disconnecting from the server. The bandwidth change request message is a message sent from the client side to the server side when the current viewing quality is not optimal. The retransmission request message is a packet corresponding to the discarded portion when the packet is discarded on the network. Is a request message for sending the message again.
[0004]
Operations performed by the user include play, stop, pause, fast forward, and rewind. When the user plays, stops, or pauses the player (software for receiving stream distribution), the current counter information and operation details of the content are sent from the client side to the server side. The counter is information for specifying a playback location starting from the beginning of the content, and is usually indicated by a relative time and a frame number.
[0005]
When the user fast-forwards and rewinds, the counter and operation details when the fast-forward and rewind of the content are canceled are sent from the client side to the server side. When the user performs rewinding and fast-forwarding, a video frame corresponding to rewinding and fast-forwarding is sent, and the user can search for the position he / she wants to see while viewing the frame. Normally, when connected to a server, the stream is automatically distributed without performing a playback operation. Therefore, the reproduction operation is generally used after being stopped or paused.
[0006]
The exchange of control messages including user operations with the server is stored in the form of a log on the client, and is sent to the server when the user pauses or stops, or when stream delivery is completed. However, this method has a problem that it is sent to the server only when the stream distribution ends normally and is not sent to the server when it ends abnormally.
[0007]
The conventional technology is as described above, and in the stream distribution performed in the present invention, the user's operation is grasped by the stream distribution apparatus (server side), and aggregated and fed back to content analysis, content creation, etc. Is not done.
[0008]
[Problems to be solved by the invention]
In a streaming system in the city, there is a method for efficiently comprehending which part of the content was repeatedly viewed by counting the operations such as playback, stop, pause, fast forward, and rewind performed by each user. not exist. There is a method of recording user operations in each client and transmitting them to the stream distribution server after distribution ends. However, with the transmission method after the end of distribution, information cannot be collected if the client side does not end normally. In the present invention, as will be described later, information exchanged between the server and the client is accumulated, so that it is possible to collect information of a portion that has been normally communicated even if the client does not end normally.
[0009]
In the present invention, as described later, an intermediate IP driver (software) is installed on the server side of a streaming system in the city, a control message communicated between the stream distribution device and the client is stored, and the information is used. Provided is a means for grasping each user's operation and grasping which part is repeatedly seen or not seen from a plurality of user's operations for arbitrary content.
[0010]
This allows, for example, educational content providers to understand which parts the learner is watching repeatedly and use them for future content creation, and content creators can understand which parts of the content are better. You can see what is being seen. In addition, it is possible to automatically create a digest of content by using information indicating which part has been repeatedly viewed and information indicating which portion has not been viewed and the distributed content. By automatically creating a digest, it is possible to visually grasp the portion that has been viewed repeatedly, and it is possible to efficiently grasp the portion that has been viewed.
[0011]
In addition, by linking with a database (DB) with customer information, it provides functions to identify places with high viewing frequency for each user attribute such as age, gender, and address, and automatically create a digest for each user attribute. Thus, it is possible to efficiently grasp the viewing tendency for each user attribute.
[0012]
[Means for Solving the Problems]
In order to solve the above problems, the present invention introduces an intermediate IP driver to the server, so that when the server receives a play message, a stop message, or a pause message from each client, the message reception time, Copy and save the counter indicating the point the user is viewing and the message type (play, stop, pause). When receiving a rewind message or fast forward message from each client, the server rewinds and transmits a stream corresponding to the fast forward. When the user completes rewinding and fast-forwarding input and playback is resumed, the counter and playback message at that time are sent to the server, so the server receives the message reception time, counter, and message type using an intermediate IP driver. By saving the content, it is grasped which part of the content has been repeatedly viewed by rewinding or skipped by fast forwarding or the like.
[0013]
In solving the above problems, the present invention provides a connection request, a reproduction request, a stop request, a pause request, a rewind request, a fast forward request, and a disconnect request from one or more clients. One or more stream delivery devices that perform message tracing of playback, stop, pause, rewind, fast forward, and disconnection, and message viewing from the stream delivery device and viewing locations connected to stream delivery devices that receive and control stream frames An extraction device is used. However, since the viewing location extraction apparatus is a device in which a program having a viewing location extraction function is installed, it can also be realized by the same device as the stream distribution device.
[0014]
In addition, the stream distribution device also determines the time when stream distribution starts based on the connection request from each client, the distribution band of the bandwidth change request from each client and the time when the request is received, the number of retransmission frames from each client and the request. And a means for recording the time when a disconnection request is received from each client. In addition, it has a function for executing a reproduction request, a stop request, a pause request, a rewind request, and a fast forward request from each client, and means for recording the received time.
[0015]
Here, the user is a viewer of the distributed stream, and the client is a device operated by the user. A server is a device that delivers (including relays) a stream to a client.

It has a function of indicating whether a section (for example, a section obtained by dividing content every 1 second or every 5 seconds) is repeatedly viewed. This function shows, for example, the cumulative viewing frequency in a section in a tabular format or graph.
[0021]
The fourth feature of this system is that the viewing location extraction device 4 uses the messages stored in the second feature to determine which operation is performed by each user and the content counter position for each content. It has a function of performing cumulative processing for a plurality of users as to whether the time (for example, a section in which content is divided every second or every five seconds) has been repeatedly viewed (whether the cumulative frequency in the section is large).
[0022]
The fifth feature of the present system is that the viewing location extraction device 4 uses the messages accumulated in the second feature to determine which operation is performed by each user and the content counter position for each content. It is determined whether the time (for example, the section in which the content is divided every 1 second or 5 seconds) was repeatedly viewed (whether the cumulative frequency in the section is large), and the viewing frequency is determined from the specific number of times based on the result and the delivered content. It has a function to create digest version contents of many parts.
[0023]
