Video Display Device Feature Extraction for Enhanced Service Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadcasting systems limit the ability of video display devices to receive and provide enhanced services directly from broadcasting stations due to bandwidth constraints and the reliance on intermediate devices that may exclude or add enhanced service data, resulting in incomplete or inadequate service delivery.
Innovation Solution
A method for video display devices to extract feature information from received audio-visual content, transmit this information to a server, and retrieve corresponding enhanced services, content information, and database entries, allowing for the selection of appropriate content recognition modules and sampling parameters to efficiently recognize and provide enhanced services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If broadcast receiving device extracts only main AV data and provides uncompressed audio-visual data to video display device, then video display device can display high quality content, but enhanced services from broadcasting station are not available
Solution Approach 1:
The system separates the acquisition of main AV data and enhanced service data into independent parallel paths. The video display device independently acquires feature information from main AV data and queries enhanced service data from the broadcasting station through network communication, rather than relying solely on the broadcast receiving device's extraction and transmission.
Solution Approach 2:
The patent introduces a network server as an intermediary between the broadcasting station and the video display device. The server receives feature information from the video display device, matches it with content databases, and retrieves corresponding enhanced service data, enabling indirect access to enhanced services while maintaining high-quality content display.
2Adaptability or versatility
If MVPD extracts and converts content signals, then content format compatibility is improved, but enhanced service data may be excluded or replaced
Solution Approach 1:
The video display device performs preliminary extraction of feature information from the received main AV data before requesting enhanced service data. This allows the device to identify what enhanced services are needed and query them proactively, ensuring that enhanced service data is obtained even after MVPD conversion processes.
Solution Approach 2:
The system implements a feedback mechanism where the video display device sends extracted feature information to the network server, which then returns matching enhanced service data. This closed-loop feedback ensures that enhanced service data integrity is maintained despite intermediate processing by the MVPD.
3Reliability
If wireless channel bandwidth is limited, then transmission stability is improved, but enhanced service delivery is insufficient
Solution Approach 1:
The patent transitions from a single wireless transmission dimension to multiple dimensions by combining local feature information extraction with network-based data retrieval. Instead of relying solely on wireless bandwidth for enhanced service delivery, the system uses network communication to supplement bandwidth-limited wireless channels, effectively adding another dimension to data delivery.

AI summary
Provided are a method of receiving an enhanced service and a video display device thereof. The method includes: receiving an audio-visual (AV) content; extracting first feature information from the received AV content; receiving a database including at least one of content information, enhanced service information, and an enhanced service, which correspond to the first feature information, from a first server by transmitting the extracted first feature information to the first server; storing the database received from the first server in a memory; extracting second feature information from the received AV content; and searching and obtaining one of content information, enhanced service information, and an enhanced service, which correspond to the extracted feature information, from the database.
