Broadcast Frame Identification for Multi-Format Test Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack a method to effectively identify and manage multiple transmission formats in test streams used for digital broadcasting, leading to potential incorrect format selection and reduced convenience.
Innovation Solution
A data processing apparatus and method that adds identification information to transmission frames, allowing for the identification of transmission formats, thereby enabling correct format selection and enhancing convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple transmission formats are made available in a transmission frame for test streams, then the versatility and adaptability of the system is improved, but the ability to correctly identify and select the appropriate format deteriorates due to lack of identification information
Solution Approach 1:
The patent applies preliminary action by adding identification information to the transmission frame in advance, before the receiver needs to select a transmission format. This pre-prepared identification data enables the receiver to correctly identify and select the appropriate format without ambiguity, resolving the contradiction between having multiple formats available and being able to identify them correctly.
2Device complexity
If no identification information is added to transmission frames, then the device complexity is reduced, but the ease of operation deteriorates because correct format selection becomes difficult
Solution Approach 1:
The patent applies segmentation by separating the identification function from the transmission format itself. The identification information is extracted and added as a distinct element to the transmission frame, allowing receivers to easily identify and select formats without complex analysis of the entire frame structure. This resolves the contradiction by making format selection convenient while keeping the added complexity minimal and localized.
Data Source
AI summary
The present technology relates to a data processing apparatus and a data processing method capable of achieving higher convenience in a case where a plurality of transmission formats is available in a transmission frame. The data processing apparatus installed in a transmission-side facility processes a transmission frame transmitted as a broadcast signal and adds identification information for identifying the transmission format of the transmission frame, while a data processing apparatus installed in a reception-side facility processes a transmission frame in which a transmission frame has been identified, on the basis of identification information added to the transmission frame transmitted as the broadcast signal. The present technology can be applied as a method of a test stream, for example.
