Reception Apparatus Bearer Selection via Control Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack an efficient method for appropriately selecting bearers transmitted by multiple transmission systems for content delivery, particularly in OTT-V streaming, which affects network resource management and content distribution.
Innovation Solution
A reception apparatus and method that acquire and utilize control information to identify and manage bearers across different transmission systems, such as ATSC3.0 and 3GPP-MBMS, using extended LSID to map ROUTE sessions to various transport bearers, enabling efficient data transmission and bearer selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If data is transmitted through multiple transmission systems (MC and BC bearers), then network resource loads are decreased, but it becomes difficult to appropriately select and manage bearers from different transmission systems
Solution Approach 1:
The patent introduces control information as an intermediary element that mediates between multiple transmission systems and the reception apparatus. This control information contains bearer identification information and acquisition information, enabling the reception apparatus to automatically select appropriate bearers without complex manual configuration or management, thus resolving the contradiction between utilizing multiple transmission systems and maintaining simple bearer management
Solution Approach 2:
The control information structure is designed to be universal across different transmission systems (both MC and BC). By using a standardized control information format that can identify and describe bearers from various transmission systems, the system achieves multi-functionality in handling diverse bearer types through a single unified mechanism, reducing the complexity of managing different transmission systems
2Measurement precision
If control information is acquired from multiple transmission systems, then bearer identification accuracy is improved, but information acquisition overhead increases
Solution Approach 1:
The control information is segmented into distinct functional components: acquisition information (for acquiring data transmitted through a session in a first transmission system at a first layer) and bearer identification information (for identifying a bearer that transmits the data in a second transmission system at a second layer lower than the first layer). This segmentation allows the reception apparatus to process only the necessary portions of control information for each transmission system, reducing overall information overhead while maintaining accurate bearer identification
Solution Approach 2:
The patent organizes control information across multiple layers (first layer and second layer lower than the first layer) of a protocol stack. By distributing bearer-related information across different protocol layers, the system achieves comprehensive bearer identification without concentrating all control information in a single location, thereby reducing the overhead at any single layer while improving identification accuracy

AI summary
The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method and more particularly to a reception apparatus, a reception method, a transmission apparatus, and a transmission method, by which bearers transmitted by a plurality of transmission systems are selected appropriately. The reception apparatus acquires control information including information for acquiring data transmitted through a session in a first transmission system at a first layer in a protocol stack of an IP (Internet Protocol) transmission system and for identifying a bearer that transmits the data in a second transmission system at a second layer lower than the first layer; and controls an operation of each unit that acquires the data transmitted on the bearer on the basis of the control information. The present technology is applicable to a television receiver corresponding to ATSC3.0, for example.
