Image Processing Apparatus Thumbnail Generation for Channel Browsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing apparatuses lack efficient methods for displaying and browsing multiple channels and external input signals simultaneously, making it difficult for users to intuitively recognize and manage various broadcasting and input contents.
Innovation Solution
The apparatus employs two tuners and demodulators to process and display multiple channels, along with a channel browsing processing circuit that extracts and re-encodes partial images into a transport stream format, allowing for thumbnail views of channels and external input signals, enabling intuitive content recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple channels and external input signals are displayed simultaneously, then content recognition is improved, but device complexity increases
Solution Approach 1:
The display screen is divided into multiple regions, with each region dedicated to displaying a specific channel or external input signal. This segmentation allows simultaneous display of multiple content sources without requiring complex switching mechanisms, as each content type has its own designated display area.
Solution Approach 2:
The display apparatus is designed to handle multiple types of input signals (broadcast channels and external inputs) through a unified display framework. The same display screen and control interface serve multiple functions, displaying different content types simultaneously without requiring separate dedicated displays for each input source.
2Ease of operation
If thumbnail views of multiple channels are generated and displayed, then ease of operation is improved, but use of energy increases
Solution Approach 1:
Instead of processing and displaying full-resolution images for all channels simultaneously, the system generates and displays reduced-size thumbnail views. This partial action approach provides sufficient information for content recognition while significantly reducing the computational energy required for image processing and display rendering.
Data Source
AI summary
An apparatus for processing images may include a de-multiplexer that receives a data stream and de-multiplexes a video signal and channel information from the data stream, a first decoder that provides a decoded video signal, a thumbnail generator coupled to the first decoder to generate at least one of a still picture thumbnail or a moving picture thumbnail based on the decoded video signal, and an encoder coupled to the thumbnail generator and the de-multiplexer. The encoder encodes the thumbnail with the channel information to provide a thumbnail data stream to provide thumbnails of moving pictures and/or still pictures on a display.
