Channel Overlay Navigation for Faster TV Channel Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video processing apparatuses have complex and inconvenient user interfaces that make it difficult for users to select desired channels among numerous options, often requiring multiple manipulations and occupying significant screen space.
Innovation Solution
A video processing apparatus with a memory to store character strings corresponding to channels, a display to superpose character strings on channel pictures, and a signal receiver and controller to manage forward and backward changes, allowing users to easily navigate channels using a simple and minimal user interface with a remote controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional user interface is used to allow channel selection among hundreds of channels, then channel selection capability is provided, but the interface becomes complicated and requires many manipulations
Solution Approach 1:
The patent extracts the essential channel identification information (channel number and channel name) from the complex EPG-based interface and displays it directly on the screen as overlay text. This allows users to see channel identifiers without navigating through complicated menus or EPG screens, thereby maintaining channel selection capability while dramatically simplifying the user interface and reducing the number of manipulations required.
2Adaptability or versatility
If a conventional user interface is used for channel selection, then channel information display is provided, but the interface occupies a relatively large area of the screen
Solution Approach 1:
The patent transitions from a traditional full-screen or large-area menu-based interface to a minimal overlay approach where channel information is displayed in a compact format directly on top of the video content. By using small, strategically positioned text overlays showing only essential channel identifiers, the interface provides necessary channel information while occupying minimal screen area and not interrupting the user's view of the video content.
3Adaptability or versatility
If multiple manipulations are required for channel selection, then comprehensive channel control is achieved, but user time and operational complexity increase
Solution Approach 1:
The patent displays channel numbers and channel names as overlay text on the screen during normal video playback, preparing the information in advance so that users can immediately see channel identifiers without needing to navigate through menus or wait for EPG data to load. This preliminary display of essential channel information allows users to quickly identify and select desired channels, significantly reducing channel selection time while maintaining comprehensive channel control functionality.

AI summary
A video processing apparatus including a memory to store a plurality of character strings corresponding a plurality of channels in predetermined sequence, a display part to display the character string to be superposed on a picture of the corresponding channel, a signal receiver to receive a forward or backward change signal for the character string in accordance with selection of a user, and a channel selection controller to control the display part to display a character string previously or next to the character string of the channel being currently displayed such that the previous or next character string is superposed on the picture of the corresponding channel, when the signal receiver receives the forward or backward change signal for the character string. Thus, a user can easily and quickly select a desired channel from among a plurality of channels. Also, a user can select a desired channel through simple, convenient and small user interface.
