Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of efficient techniques for acquiring components configuring a service through a Real-time Object Delivery over Unidirectional Transport (ROUTE) session, which is essential for providing advanced digital broadcasting services.
Innovation Solution
A reception device and method that utilize an IP transmission scheme to efficiently acquire components such as videos, audios, or subtitles by employing a ROUTE session, where signaling data is used to access and reproduce streams of components, and broadband servers deliver additional content via the internet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ROUTE session is used for transmitting service components, then service delivery efficiency is improved, but there is no established technique for acquiring components configuring a service
Solution Approach 1:
The patent segments the service component acquisition process into distinct phases: initial service information acquisition through signaling data, followed by component-specific acquisition through ROUTE sessions. This segmentation allows the system to first obtain service metadata and then efficiently retrieve specific components, resolving the contradiction between acquisition efficiency and implementation complexity by breaking down the complex task into manageable steps
Solution Approach 2:
The patent applies preliminary action by acquiring service information and signaling data before actually acquiring the service components through ROUTE sessions. This preliminary step provides necessary metadata and configuration information that simplifies subsequent component acquisition, thereby improving overall efficiency while maintaining manageable system complexity
2Adaptability or versatility
If hybrid broadcasting and communication setup is used, then service versatility is improved, but service component acquisition becomes more complex
Solution Approach 1:
The patent implements universality by designing a component acquisition mechanism that works across both traditional broadcasting and IP-based communication environments. The ROUTE session framework provides a unified approach that can handle service components regardless of the delivery medium, thereby maintaining service versatility while simplifying the acquisition process through a common interface
Solution Approach 2:
The patent introduces signaling data as an intermediary that bridges broadcasting and communication systems. This intermediary carries service information that enables the receiver to appropriately acquire components from either broadcasting or communication channels, thus managing the complexity of hybrid setups while maintaining versatility

AI summary
The present technology relates to a reception device, a reception method, a transmission device, and a transmission method, which are capable of acquiring a component configuring a service efficiently, appropriately, and easily. A reception device acquires second metadata including first and second flags, the first flag indicating whether or not it is possible to acquire components configuring a service through only first metadata, the second flag indicating whether or not there is a stream of a component transmitted from a server on the Internet by way of communication among the streams of the components configuring the service, the first metadata including information related to a stream of a component transmitted by way of broadcasting through a broadcast wave of digital broadcasting using an Internet Protocol (IP) transmission scheme, acquires the first metadata based on the second metadata, accesses the stream of the component transmitted by way of the broadcasting based on the first metadata, and controls reproduction of the component. The present technology can be applied, for example, to a television receiver.
