Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The automatic generation of metadata for broadcast programs requires significant processing power, making it challenging to efficiently process information extracted on a per-frame basis using limited system resources.
Innovation Solution
A receiving apparatus and metadata generation system that includes a data processing component to generate conversion data from broadcast signals, enabling the generation of metadata representing the content of the broadcast program, and a transceiver component to transmit this data to a server apparatus for further processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic metadata generation is performed using AI on broadcast program information extracted on a per-frame basis, then metadata representing content can be generated, but the processing load becomes too heavy for limited system resources
Solution Approach 1:
The patent divides the metadata generation system into two segments: a receiving apparatus that performs initial processing of broadcast signals to extract program information, and a server apparatus that performs the computationally intensive AI-based metadata generation. This segmentation allows the receiving apparatus with limited resources to avoid heavy processing while still enabling automated metadata generation through the server's greater computational power.
Solution Approach 2:
The patent introduces conversion data as an intermediary format between the receiving apparatus and server apparatus. The receiving apparatus converts broadcast signals into a standardized format that can be efficiently transmitted to the server, which then processes this intermediate representation to generate metadata. This intermediary format reduces the processing burden on both systems.
2Measurement precision
If broadcast program information is processed on a per-frame basis, then detailed content information can be extracted, but the processing time and resource consumption increase significantly
Solution Approach 1:
The receiving apparatus performs preliminary processing by extracting program information from broadcast signals and converting it into a standardized format before transmission to the server. This preliminary action prepares the data in advance, allowing the server to focus computational resources on the AI-based metadata generation without needing to perform initial extraction and conversion, thereby reducing total processing time.
Data Source
AI summary
The present application relates to a receiving apparatus and a metadata generation system. Information of a broadcast program extracted according to each frame is effectively processed using limited system resources. The receiving apparatus is a receiving apparatus for receiving a broadcast program and providing same in a live broadcast viewing mode. The receiving apparatus comprises: a data processing unit that generates converted data according to a broadcast signal of the broadcast program when live broadcast viewing of the broadcast program is provided, wherein the converted data can be used for generating metadata representing the content of the broadcast program; and a first transceiver unit that transmits the converted data to a server apparatus that generates the metadata.
