Description

System and method for transmitting and receiving interactive contents for low delay interactivity

The present invention relates to a system for transmitting and receiving interactive contents for low latency conversation, and a method and a computer readable recording medium storing a program for realizing the method. Determining the object to be stored in the buffer of the interactive content receiver by using the possible buffer size, the size of the object (MPEG: Moving Picture Experts Group) -4, and the object / scene information to be transmitted in advance, A system and method for transmitting and receiving interactive content for a low latency conversation for storing an object to be stored in a buffer in an interactive content receiving device and minimizing a delay that may occur when a user interacts with the user by using the storage object if necessary. And computer-readable recording media having recorded thereon a program for realizing the above method. Will.

MPEG-4 based interactive content is composed of object / scene information and a hierarchical structure of various objects, and includes the object / scene information. By defining the operations and behaviors of the objects in advance in the scene information, an interactive service that responds to a user's request is possible. Here, the object means media data and metadata such as audio / video / still image, data for information protection and distribution, and the like.

In order to use the interactive content for a remote conversation service through a wired / wireless communication network or a broadcasting network, the interactive content should be transmitted from an interactive content transmitter to a receiver, and a user's request from the interactive content receiver to the transmitter is required. Must be able to convey

In order to transmit the interactive content to the receiving device, the transmitting device should be able to separate the interactive content for each object and be able to transmit the separated object to the receiving device according to the object / scene information. In this case, the object / scene information may include time, location, and behavior information of each object in the scene. The user's request and time will cause the behavior of a particular object according to the object / scene information.

For a simple example of interactive content, a button image called "output" and a button image called "delete" are output at the start of the interactive content, and when a button image called "output" is clicked, a video called "image" appears. If you click on the button image "Delete", and the video called "Video" is interactive content configured to disappear from the scene, the "Output" and "Delete" buttons and the "Video" video become media objects, If you click on the button "Output", a video called "Video" appears, and if you press the "Delete" button, the object's behavior and the position where the video called "Video" disappears from the scene are included in the scene information.

In the above example, the transmitting apparatus first transmits the button image "output" and the button image "delete" to the receiving apparatus according to the object / scene information, and when the user clicks the button image "output", It is delivered to the transmitter. The transmission device transmits a video called "image" to the receiving device by the request. When the user clicks on the "delete" button image, the transmission apparatus stops transmitting the video called "image". If the user clicks the button image "output" again, the user's request is transmitted to the transmitting apparatus through the same process as described above, and the video "image" is transmitted to the receiving apparatus again. Will repeat. That is, when a user requests a specific object, this request must be transmitted to the transmitting apparatus, and the transmitting apparatus must transmit the object to the receiving apparatus, so that a delay occurs in the process of transmitting and processing the object request message of the user. If the data transmitted by the user's request is an object requiring continuous transmission such as audio or video, the buffering operation is performed at the receiving device to minimize the effect of the network. Therefore, not only the transmission delay but also the buffering generally takes several seconds. There is a problem that a delay occurs for.

Therefore, when it is necessary to transmit a specific object constituting the interactive content according to a user's request or time, there is a need for an interactive content transmission / reception system capable of minimizing delay.

1 is a block diagram of an embodiment of a system for transmitting and receiving interactive content for a low latency conversation according to the present invention.

As shown in FIG. 1, FIG. 1 is a system for transmitting and receiving interactive content for a low latency conversation according to the present invention, which includes an interactive content transmitter 10 and an interactive content receiver 20.

The interactive content transmitter 10 may include an interactive content input unit 11 for receiving interactive content input from the outside, and the corresponding interactive content received from the interactive content input unit 11 with object / scene information. The interactive content processing unit 12 for separating and analyzing each object and the receiver storage object determining unit for determining the objects to be stored in the buffer of the interactive content receiving apparatus 20 in advance among the objects constituting the interactive content. (13) and a transmitting / receiving unit 14 for transmitting the object / scene information and each object constituting the interactive content to the receiving device and receiving a message requesting the object from the receiving device according to user or time information. Equipped.

Here, the buffer refers to a device that can store data, such as a memory or a hard disk, included in the receiving device.

The interactive content receiver 20 receives the interactive content transmitted from the interactive content transmitter 10 through a wired or wireless network or a broadcast network, and transmits an object request message based on user or time information. ) A transmission / reception unit 21 for transmitting the object, an object storage determination unit 22 for determining whether to store configuration objects of the interactive content received from the transmission / reception unit 21, and an object storage determination unit 22. Decoding the object received through the buffer 23 and the transceiver 21 to store the object is determined to be necessary through the storage, and to configure the scene by placing the object in the time and space required for each object And an object and scene processing unit 24, and a user input processing unit 25 for processing the interactive request object according to a user's request.

The operation of the interactive content transmission / reception system for low latency conversation of the present invention having the structure as described above will be described in detail as follows.

2 is a flowchart illustrating a process of transmitting interactive content in a method of transmitting and receiving interactive content for a low latency conversation according to the present invention.

As shown in FIG. 2, first, the interactive content transmitter determines whether to use a predetermined value of a buffer size of a receiver necessary for determining an object to be stored in the receiver buffer.

As a result of the determination, if the buffer size of the receiver previously promised is not used, the size of the buffer that can be stored is received from the receiver (202).

As a result of the determination, if the buffer size of the receiver previously promised is used, the step 202 of receiving the size of the buffer that can be stored from the receiver is omitted.

Next, after the interactive content is input to the interactive content input unit 11 (203), the object / scene information of the interactive content input from the interactive content processing unit 12 and each object are separated, analyzed, and processed ( 204).

Thereafter, it is determined whether to store each separated object in the buffer of the receiving apparatus (205), and the objects to be stored in the buffer of the receiving apparatus are transmitted in advance (206). In this case, the objects to be stored in the buffer of the receiving apparatus are performed at the initial connection of the transmitting apparatus and the receiving apparatus, and the time required for transmission may vary according to the state of the network.

Next, the object / scene information is transmitted (207). That is, the process of transmitting the object / scene information 207 does not proceed when the process of transmitting the receiver storage object 206 is completed. When the size of the object to be transmitted is large because the buffer size of the receiver is large, the object / scene information transmission process 207 may be performed in parallel while transmitting the receiver storage object.

Next, it is determined whether there is an object to be transmitted (208). That is, the process 208 of determining whether there is an object to be transmitted is not performed when the process of transmitting a receiver storage object 206 is completed as in the object / scene information transmission process 207. The process of determining whether there is an object to be transmitted while transmitting the storage device storage object may be performed in parallel.

If it is determined that there is an object to be transmitted, the object is transmitted (209) and it is determined whether or not the service is terminated (210). When the object is transmitted 209, when the object of the receiving device stores continuous transmission such as audio or video, the object may be transmitted according to the buffer size of the receiving device.

On the other hand, if it is determined that there is no object to transmit, it is determined whether the service is terminated (210).

If it is determined that the service is terminated, the interactive content processing and transmission process is terminated.

On the other hand, if it is determined that the service is not terminated, the process proceeds to step 208 of determining whether there is an object to be transmitted.

3 is a detailed flowchart of an embodiment of a receiver storage object determining process 205 of FIG. 2.

As shown in FIG. 3, it is determined whether there is an object to determine whether to store the receiving device among the objects constituting the interactive content (301), and when it is determined that there is no object to be determined, the receiving device storage object is determined. The process is terminated, and if there is an object to be determined, it is determined whether the object priority is determined (302).

As a result of the determination, if the priority for each object is determined, the object information is input in order from the object having the highest priority (303). If the priority is not determined, the object information is input in any order (304). Here, the object information means additional information related to the object, such as the size of the object, the location in the file, and whether or not an event is set.

Next, if it is determined that the object is an interactive object (305), if it is determined that the object is not an interactive object, it is determined that it is not a receiving device storage object (307), and determining whether there is an object to determine whether the receiving device is stored ( Proceed to 301).

On the other hand, if it is determined that the interactive object, it is determined whether the size of the object is within the buffer size of the receiving device (306). Here, the interactive object means an object whose behavior is defined by a user's request or time.

If it is determined in step 306 that the object is within the buffer size of the receiver, if the object is an object to be transmitted in one transmission, such as a still image, the size of the object is determined to be within the buffer size of the receiver. After determining as the receiver storage object (308), the buffer size of the receiver device that can be stored is reduced by the size of the receiver storage object (309). If, in the determination step 306, the object is an object requiring continuous transmission such as audio or video, if a part of the stream of the object is determined to be within the buffer size of the receiving device, it is determined as the receiving device storage object (306). ). The amount of part of the object stream is a value that may vary depending on the person implementing it.

On the other hand, if it is determined that the size of the object or part of the object stream is not within the buffer size of the receiver, it is determined that the receiver is not a storage device (307), and whether there is an object to determine whether or not to store the receiver Proceed to step 301.

4 is a flowchart illustrating a process of receiving interactive content in a method of transmitting and receiving interactive content for a low latency conversation according to the present invention.

As illustrated in FIG. 4, the interactive content receiving apparatus 20 first determines whether to use a predetermined value of a buffer size of a receiving apparatus required for determining an object to be stored in the receiving apparatus (401).

If it is determined that the buffer size of the receiver previously promised is not used, the size of the buffer that can be stored by the receiver is transmitted to the interactive content transmitter 10 (402).

On the other hand, if it is determined that the previously used buffer size of the receiving device is determined, the step 402 of transmitting the storeable buffer size of the receiving device may be omitted.

Next, it is determined whether there is an object received (403).

If it is determined that no object is received, it is determined whether the service using the interactive content is terminated (403). If the service is terminated, the reception and processing of the interactive content is terminated, and the service using the interactive content is determined. If is not terminated, the process proceeds to step 403 to determine whether there is a received object.

On the other hand, if it is determined in step 403 that there is a received object, if it is determined that there is a received object, a configuration object of interactive content is received (405), and it is determined whether the received object is an object to be stored in a buffer of the receiving device. (406).

If it is determined that the object is not an object to be stored in the receiving device, the object and the scene are processed because the object is transmitted by the necessity of scene composition rather than the object transmitted for storage (409). The object and scene processing refers to a process for generating a scene of interactive content such as decoding an object, scene composition, and rendering.

On the other hand, if it is determined that the object to be stored in the receiving device, it is stored in the buffer of the receiving device (407) and it is determined whether or not to process the object (408).

If it is determined that the object needs to be processed, the object and the scene are processed (409). If it is determined that the object is not needed, the process of determining the received object after omitting the object and the scene processing is omitted. Proceed to 403.

5 is a flowchart illustrating an example of an interactive object processing process when a user requests a process of receiving interactive content in a method of transmitting and receiving interactive content for a low latency conversation according to the present invention.

As shown in FIG. 5, if there is a request of an interactive object by a user or time (501), it is determined whether the requested interactive object is an object stored in a buffer (502).

If it is determined that the object is stored in the buffer, the requested interactive object is input from the buffer (503), and the requested interactive object is processed (506). If it is determined in the object processing process 506 that the transmission is not completed, the scene is displayed by the data stored in the buffer and the corresponding interactive object is requested by the interactive content transmission device, and then the data is stored in the buffer. Receive from the data.

On the other hand, if it is determined that the object is not stored in the buffer request the interactive object to the interactive content transmission device (504), after receiving the interactive object from the interactive content transmission device (505), the request The interactive object being processed (506).

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).
