Abstract

A system for the orchestral media service which receives the orchestral media having multiple tracks and neodata from a media service provider and shares the data with multiple connected devices to play, includes: a client engine that parses the orchestral media to separate into each audio/video and neodata, combines the audio/video into one resource to play, synchronizes with the connected devices with a basis of the playback time of the main audio/video, analyzes the neodata, maps the neodata into control command to transfer to the connected devices, and outputs the mapped control command; and a communication interface that performs connection with the devices having respective communication systems and transfers the control command to the connected devices.

Claims

1. A system for the orchestral media service which receives the orchestral media having multiple audio/video tracks and neodata from a media service provider and shares the data with multiple connected devices to play, the system comprising:

a client engine that parses the orchestral media to separate into each audio/video and neodata, renders main the audio/video from the multiple audio/videos on output device like television, synchronizes with the connected devices with a basis of the main audio/video'"'"'s playback time, analyzes the neodata, maps the effect data of the neodata into control command to activate the connected passive devices; and

a communication interface that performs connection with the devices having respective communication systems and transfers the control command to the connected passive devices.

2. The system of claim 1, wherein the client engine includes:

a main controller that manages current synchronization time to play the orchestral media and parses the orchestral media to separate into each audio/video and neodata;

an A/V player module that plays the main audio/video transferred from the main controller;

a parser module that analyzes the neodata received from the main controller and maps the effect inside the neodata into control command to activate the connected passive devices;

a synchronization module that receives the playtime of the main audio/video from the A/V player module and the execution time and control command for passive devices from the parser module and synchronizes with the active devices which receives each audio/video track except main audio/video and passive devices which the control command is to be transferred; and

a device controller that performs connection with the active and passive devices and transfers the control command to the connected active and passive devices.

3. The system of claim 2, wherein the main controller includes:

a main clock manager that manages the whole devices times with a basis of the main audio/video time played through the A/V player module;

a media parser that parses the orchestral media to separate multiple audio/video tracks and neodata including effect information listed by time and scene; and

an A/V controller that transfers the separated multiple audio/video tracks to the A/V player module.

4. The system of claim 2, wherein the player part includes:

a buffer that stores the audio/video data transferred from the main controller;

a sync that synchronizes the audio/video data stored in the buffer;

a renderer that renders the synchronized audio/video data to make it one resource;

a decoder that decodes the rendered resource to output; and

a multi track sender that transfers the audio/video data of different tracks to the connected active device through wired or wireless interface.

5. The system of claim 2, wherein parser module includes:

a parsing table that stores the neodata received from the main controller to perform buffering;

a neodata analyzer that analyzes an effect information included in the neodata to confirm a data structure; and

a neodata mapper that maps the analyzed control command through transforming into control command appropriate for respective devices.

6. The system of claim 5, wherein the data structure of neodata comprises at least one among, effect type, start time, duration, and effect value.

7. The system of claim 2, wherein the synchronization module includes:

a sync table that performs buffering on the mapped data received from the parser module;

a sync time checker that continuously checks synchronization among the connected active devices in accordance with a time of the main clock manager;

a sync table updater that corrects control information by considering an actual execution time of the connected devices; and

a device control interface that is connected with the device controller to send control command and receive feedback.

8. The system of claim 7, wherein the actual execution time of the devices is calculated by subtracting activation time of device and network delay time from start time of device.

9. The system of claims 8, wherein the execution time, when the device is an active device, is:

a sum of a delay time produced to process command and a time taken to read media in actuator side, a processing delay time in the active device receiving audio/video data and a time used to play audio/video data.

10. The system of claims 2, wherein the control command mapped in the parser module comprises:

at least any one among device type, device identification number, connection interface, execution time, control type and control value.

11. The system of claim 2, wherein the device controller performs connection with the active devices or passive devices through communication application program interface and sends control command and receives feedback with the connected active or passive devices.

12. A method for the orchestral media service, comprising:

mapping that analyzes the neodata and maps the neodata into control command to transfer to the connected respective devices; and

transferring that transfers the mapped control command to the passive devices and each audio/video except main audio/video to the active devices.

13. The method of claim 12, wherein the playing back process includes:

a synchronization that synchronizes each audio/video data;

a rendering that combines the synchronized audio/video data into one resource;

a decoding that decodes the combined resource; and

a transferring that transfers the decoded resource to the corresponding devices.

14. The method of claim 12, wherein the mapping process includes:

a buffering that stores the neodata and performs buffering;

a confirming that analyzes a data structure of the neodata and confirms control command to realize effect information included in the neodata; and
