Hybrid Broadcast Communication Synchronization via Application Control Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional broadcast communication cooperative services face delays in accessing and synchronizing communication contents due to the lack of efficient methods for quickly accessing communication contents and selectively receiving broadcast contents, particularly in Hybridcast standards, which cannot cope with high-definition synchronous reproduction of broadcast and communication contents.
Innovation Solution
A transmitting method that includes application control information for synchronizing contents transmitted via both broadcast waves and communication paths, allowing quick access and synchronization of contents on the receiving side by including location and reference clock synchronization information, enabling simultaneous reproduction of broadcast and communication contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If contents are transmitted using both broadcast wave and communication path, then content distribution capability is improved, but access delay and synchronization difficulty increase
Solution Approach 1:
The patent applies preliminary action by including access information for communication contents directly in the broadcast wave transmission. The receiving apparatus obtains location information and access URLs through broadcast before needing to access communication contents, allowing immediate retrieval without waiting for communication network responses. This resolves the access delay issue while maintaining the versatility of dual-path transmission.
Solution Approach 2:
The patent uses broadcast wave as an intermediary to deliver access information that enables subsequent communication content retrieval. The broadcast transmission serves as a mediator that provides location information and access details, allowing the receiving apparatus to efficiently access communication contents without direct broadcast-communication interaction delays.
2Adaptability or versatility
If contents are transmitted using both broadcast wave and communication path, then content distribution capability is improved, but synchronization complexity increases
Solution Approach 1:
The patent applies preliminary action by embedding timing information and synchronization data in the broadcast wave before communication contents are accessed. The receiving apparatus receives reference timing information through broadcast in advance, enabling it to synchronize communication contents with broadcast contents without complex real-time synchronization protocols.
Solution Approach 2:
The broadcast wave serves as an intermediary that carries synchronization timing information to the receiving apparatus. This intermediary mechanism provides a common time reference that simplifies the synchronization process between broadcast and communication contents, reducing the complexity of coordinating dual-path transmissions.
3Speed
If quick access to communication contents is enabled, then content retrieval speed is improved, but information organization complexity increases
Solution Approach 1:
The patent applies segmentation by dividing access information into distinct components: location information, access URLs, timing information, and synchronization data. Each component is separately organized and transmitted through the broadcast wave, allowing the receiving apparatus to retrieve only the necessary segments for quick access without processing unnecessary information, thus maintaining simplicity despite enhanced functionality.
Solution Approach 2:
The patent applies local quality by providing specific access information tailored to different communication contents within the broadcast transmission. Each content segment has its own location information and access parameters embedded in the broadcast wave, allowing the receiving apparatus to efficiently access only the required content without organizing or processing information for all possible contents, reducing overall organizational complexity.

AI summary
A transmitting method for transmitting contents using a broadcast wave and a communication path comprises: an information transmitting step of, including content information in application control information when transmitting the contents using both the broadcast wave and the communication path, the content information being information for synchronizing a content transmitted by using the broadcast wave with a content transmitted by using the communication path at a reception side that receives the contents and being related to the content transmitted by using the communication path and transmitting the application control information by using at least the broadcast wave in the broadcast wave and the communication path. As a result, a contents transmitting method is provided for enabling a quick access to contents through communication when the contents are reproduced by a combination of broadcast and communication on the receiving side.
