The present invention also provides a method for providing information capable of acquiring the service and contents.

In addition, the present invention provides a method for providing requirement information of a terminal capable of using the service and contents.

The present invention also provides a method for providing information about special functions in a system.

According to the present invention, a new table can be defined in the MMT to provide information on services and contents.

Also, according to the present invention, it is possible to facilitate acquisition of information on the service and content, and to provide information that can acquire the service and content.

In addition, the present invention can provide information on requirements of a terminal that can use the service and contents and information on special functions in the system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the same configurations of the drawings denote the same reference numerals as possible whenever possible.

It will be apparent to those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims and their equivalents. I will do it. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Layer C

Layer C controls MME Asset delivery, MMT Item delivery and MMT Encapsulator delivery and provides all the information and functions required for MMT Item consumption.

The functions provided by layer C are as follows.

Information Table Provision: The various information tables provide the information required for MMT Item consumption.

Connection Management: Efficient QoE for MMT Encapsulator controls layer T and provides point-to-point connection between MMT server and MMT client.

Device Capability Management: Provides static device capability information, monitors dynamic device capability, and manages software, firmware, and applications.

System Specific Function Provisioning: Some systems may have optional features required for MMT Item consumption. Typical examples are Audience Measurement Function and Downloadable DRM function.

Layer C data generation: Layer C has data transmitted by layer T. They are information tables, commands for device capability management, and data from system specific functions.

 Session Management: Controls layer T to provide efficient QoS for MMT T Frame.

Hybrid Network Synchronization: Provides synchronization information for hybrid network delivery.

Next, the operation of the layer C1 and the operation of the layer C2 will be described.

Layer C1 (only communicating with layer E1 / E2)

Layer C1 provides information tables for MMT Item consumption, connection management functions, device capability management, system specific information, and security.

Information table

The MPEG2 TS has five different tables for program information. They are PMT, PAT, CAT, NIT and TDT. When the TS was designed for the first time, these five tables were sufficient. However, considering the hybrid network environment and the hybrid content consumption environment, these tables need to be expanded. In addition, new tables are required for hybrid content consumption.

The information tables for MMT are as follows.

MMT Asset Configuration Information Table (MACIT)

MMT Item Configuration Information Table (MICIT)

MMT Service Information Configuration Information Table (SICIT)

Delivery Information Table (DIT)

Specific Function Information Table (SFIT)

Device Capability Information Table (DCIT)

TDT can be reused.

1. MMT Asset Configuration Information Table

MACIT provides information for MMT Asset and is similar to PMT. The difference between MACIT and PMT is that MACIT provides a wide range of assets, including applications and web pages, and the device capabilities required for MMT Asset comsuption.

MACIT is shown in Table 1 below. More fields can be added in Table 1.

In Table 1, Table ID is the ID of MACIT, Version is the version of MACIT, and MACIT Transmission Time Info provides information on the start time and repetition period of MACIT transmission. The MMT ASSET ID is mapped to information about the MACIT. Required Device Capabilities are the device capabilities required for MMT Asset consumption. Component Relation Info describes the relationship of the components in the MMT Asset. Component Info is information about the n components in the MMT Asset.

2. MMT Item Configuration Information Table

MICIT provides information for MMT items and is similar to PAT. The difference between MICIT and PMT is that MACIT provides relevant information between assays to provide MMT items of hybrid service type.

MICIT is shown in Table 2, and more fields can be added.

*

In Table 2, Table ID is the ID of the MICIT, Version is the version of the MICIT, and MICIT Transmission Time Info provides information on the start point and repetition period of the MICIT transmission. The MMT ITEM ID is mapped to information about the MICIT. Required Device Capabilities are the device capabilities required for MMT Item consumption. Asset Relation Info describes the relationship of MMT Assets in MMT Item. Asset Info is information about n assets in the MMT Item.

3. Service Information Configuration Information Table

SICIT provides information on all information tables. With SICIT, the MMT device easily checks which information tables are to be transmitted or which information tables are to be updated.

SICIT is shown in Table 3, and more fields can be added.

In Table 3, Table ID is the ID of the SICIT, Version is the version of the SICIT, SICIT Info provides information on the start time and repetition period of the SICIT transmission, and provides the position of the SICIT when the device can not access through the interaction network do. The Information Table Info provides information about all of them. Each information table consists of IT ID, version, IT transmission time, IT repetition period, IT access location and IT access 2 ^nd location. For 2 ^nd location, the device can connect through the interaction network.

4. Delivery Information Table

The DIT provides delivery information on MMT Assets and MMT Items. DIT is especially useful when MMT Assets and MMT Items are transmitted through the network. DIT Type 1 provides delivery information in terms of MMT Asset and / or MMT Item, and DIT Type 2 provides delivery information in the network side.

The DIT is as shown in Table 4 and Table 5, and more fields can be added.

In Table 4, Table ID is the ID of the DIT, Version is the version of the DIT, DIT Info provides information on the start time and repetition period of the DIT transmission, and provides the location of the DIT when the device can not access through the interaction network do. Delivery Table Info provides information for accessing each MMT Asset or MMT Item. Two different connection information are provided for each MMT Asset or MMT Item. The first information is used when the MMT Asset or MMT Item is transmitted through the broadcasting network, and the second information is used when the MMT Asset or MMT Item is transmitted through the interaction network.

In Table 5, Table ID is the ID of the DIT, Version is the version of the DIT, DIT Info provides information on the start time and repetition period of the DIT transmission and provides the location of the DIT when the device can not access through the interaction network do. The Delivery Table Info provides information about the network through which the device can access a set of MMT Assets or MMT Items.
