Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no established technical method to provide Non Real Time (NRT) service in digital broadcasting using an IP transmission method, which is a limitation in delivering services that do not require real-time viewing or listening.
Innovation Solution
A reception apparatus and method that includes a channel selection control unit for selecting digital broadcasting channels using IP transmission, an acquisition control unit for acquiring applications based on signaling information transmitted above the IP layer, and an application execution unit for executing the acquired applications, along with a transmission apparatus that generates and transmits signaling information for application acquisition during digital broadcasting using IP transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IP transmission method is used for digital broadcasting, then service flexibility and adaptability are improved, but there is no established technical method to provide NRT service
Solution Approach 1:
The patent introduces signaling information as an intermediary element that bridges the IP transmission method and NRT service delivery. The signaling information includes application identification information and resource identification information, enabling the receiver to acquire and execute applications without requiring a pre-established NRT service framework. This intermediary mechanism allows NRT services to be provided through IP-based digital broadcasting by mediating between the transmission medium and the service application.
2Adaptability or versatility
If application acquisition is controlled based on signaling information above IP layer, then NRT service delivery is enabled, but device complexity increases
Solution Approach 1:
The patent segments the application acquisition process into distinct functional components: (1) receiving signaling information containing application and resource identification, (2) acquiring applications based on application identification, (3) acquiring resources based on resource identification, and (4) executing applications with associated resources. This segmentation allows the complex acquisition control function to be divided into manageable steps, reducing implementation complexity while maintaining full NRT service delivery capability.
Solution Approach 2:
The signaling information is prepared in advance and embedded in the broadcast signal before transmission. The application identification information and resource identification information are pre-organized in the signaling structure, allowing the receiver to perform acquisition operations efficiently without complex real-time decision-making logic. This preliminary organization of acquisition data simplifies the runtime control complexity.

AI summary
The present technology relates to a reception apparatus, a reception method, a transmission apparatus and a transmission method in which NRT service is provided in digital broadcasting using an IP transmission method. There is provided a reception apparatus including: a channel selection control unit that performs a channel selection control of channel-selecting digital broadcasting using the IP transmission method; an acquisition control unit that controls acquisition of an application delivered through broadcasting or communication in the digital broadcasting based on signaling information transmitted at a layer higher than an IP layer in a protocol layer of the IP transmission method; and an application execution unit that executes the application acquired. The present technology is applicable to a television receiver, for example.
