Multi-PIP Channel Display for Broadcast Receiver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in selecting desired channels among multiple broadcasting options due to the lack of comprehensive channel information display, requiring extensive time and key input operations in existing digital broadcast receivers.
Innovation Solution
A broadcast receiver and method that utilize a video processor to process channels in a multi-PIP mode, combining video signals with graphically processed channel data to display channel information on a TV screen, allowing users to view multiple channels' information simultaneously, reducing the need for extensive searching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only channel number is displayed for channel edition, then device complexity is reduced, but user operation becomes more difficult and time-consuming
Solution Approach 1:
The display screen is segmented into multiple picture-in-picture regions, each showing a different channel's video signal simultaneously. This allows users to view multiple channels at once without requiring complex search operations, directly improving channel selection ease while maintaining manageable display complexity through structured segmentation.
Solution Approach 2:
The system transitions from displaying channel information in a traditional list format to a visual spatial arrangement where multiple channel video signals are displayed simultaneously in different picture regions. This dimensional change from 1D list to 2D spatial display enables users to perceive multiple channels at once, significantly improving operation ease.
2Loss of time
If users refer to broadcasting program list to acquire channel information, then channel information can be obtained, but user input time increases
Solution Approach 1:
The system pre-displays video signals from multiple channels simultaneously in the picture-in-picture arrangement before the user needs to select a channel. This preliminary action eliminates the need for users to sequentially search through program lists, directly reducing channel selection time and improving search efficiency.
Solution Approach 2:
The display continuously shows multiple channel video signals in real-time, allowing users to immediately identify and select desired channels without interruption or sequential searching. This continuous display of useful information eliminates idle search time and maintains constant productivity in channel selection.
3Loss of information
If multiple channels are displayed in multi-PIP mode, then channel information visibility improves, but processing requirements increase
Solution Approach 1:
The processing system is segmented into separate picture-in-picture processing units, each handling a specific channel's video signal independently. This segmentation allows the system to process multiple channels simultaneously without overwhelming complexity, as each processing unit operates on a single channel's data while the overall system coordinates multiple units.
Data Source
AI summary
A broadcast receiver and a method for displaying channel information are disclosed, in which video signals of each channel are displayed in a multi-PIP mode when a channel list is displayed, so that a user can identify the channel list through video. Therefore, since broadcasting channel program information is displayed in real time in the multi-PIP mode of a video type, the user can share the broadcasting information with a broadcasting station in real time. Also, since the user can readily identify information on various broadcasting channels on a channel edition screen, it is possible to facilitate channel edition.
