Video Display Enhanced Service Reception via Content Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video display devices rely on Multichannel Video Programming Distributors (MVPDs) for enhanced services, limiting their ability to receive and play enhanced services independently, as they primarily receive uncompressed audio-visual content without embedded enhanced service data.
Innovation Solution
A video display device and method that execute an enhanced service playing application, obtain uncompressed audio-video content, and transmit requests to an enhanced service server to receive and play enhanced services independently, without relying on specific channels or MVPDs, using watermark or fingerprint-based content recognition for service information extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If video display devices receive uncompressed audio-visual content from broadcast receiving devices, then the display quality is improved, but the ability to receive enhanced services independently deteriorates
Solution Approach 1:
The patent introduces an enhanced service providing server as an intermediary between the broadcast receiving device and the video display device. This server receives content information from the video display device, retrieves enhanced services from the MVPD, and delivers them back to the video display device, enabling independent enhanced service reception while maintaining uncompressed video display quality
Solution Approach 2:
The patent segments the enhanced service delivery process into separate components: content information extraction from uncompressed video, independent server communication for service requests, and separate enhanced service delivery. This allows the video display device to maintain its primary function of displaying uncompressed video while independently acquiring enhanced services through a separate communication channel
2Device complexity
If enhanced services are provided through MVPD-dependent broadcast receiving devices, then service delivery is simplified, but device independence and user flexibility deteriorate
Solution Approach 1:
The patent enables the video display device to perform self-service by directly requesting and receiving enhanced services from the enhanced service providing server using its own processor and communication interface. The device extracts content information independently, formulates service requests autonomously, and receives enhanced services without requiring the broadcast receiving device to act as an intermediary, thereby achieving device independence while maintaining relatively simple service delivery through standardized protocols
3Illumination intensity
If broadcast receiving devices extract and provide only uncompressed audio-visual data, then video display quality is improved, but enhanced service availability deteriorates
Solution Approach 1:
The enhanced service providing server acts as an intermediary that retrieves enhanced service data from the MVPD based on content information received from the video display device. This mediator fills the information gap created when the broadcast receiving device strips enhanced service data during compression, allowing the video display device to obtain both high-quality uncompressed video and relevant enhanced services through separate channels
Data Source
AI summary
Provided are a video display device and a method of operating the same. The method includes: executing an enhanced service playing application not dependent on any single channel; obtaining an uncompressed audio video (AV) content; playing the uncompressed AV content through the display unit; attempting to obtain contents information on the uncompressed AV content on the basis of a part of the uncompressed AV content; transmitting an enhanced service request message to an enhanced service providing server not dependent on any single channel by the enhanced service; receiving an enhanced service from the enhanced service providing server; and playing the enhanced service through the display unit by the enhanced service playing application.
