Broadcast Receiving Apparatus Genre-Based Channel Group Zapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of broadcast channels increases, users face significant time constraints when selecting a desired channel using sequential search methods, necessitating a more efficient method for channel selection.
Innovation Solution
Implementing a method for channel zapping that groups channels by genre, allowing users to select a channel group and perform zapping within that group, as well as switch between channel groups in the same or higher/lower class, using user authentication and external input commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sequential search method is used to change channels, then user can check programs on each channel, but time required to select desired channel increases significantly
Solution Approach 1:
The patent segments the large set of broadcast channels into multiple channel groups based on genre categories (e.g., news, sports, entertainment, education). This segmentation allows users to navigate to a desired channel group first, then select from a smaller subset of channels within that group, significantly reducing the time required to find a desired channel compared to sequential searching through all channels.
2Productivity
If channels are classified into multiple groups by genre, then user can select channel more efficiently, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-classifying channels into genre-based groups before the user needs to select a channel. The channel group information is prepared in advance and stored in the broadcast receiving apparatus, allowing users to immediately access organized channel lists without requiring complex real-time processing or user-initiated classification operations.
3Speed
If group zapping is implemented across multiple channel groups, then user can navigate channels more quickly, but control complexity increases
Solution Approach 1:
The patent implements a nested structure where channel groups are organized hierarchically within genre categories. The zapping function operates at two levels: first navigating between channel groups within a selected genre, then selecting specific channels within the current channel group. This nested organization simplifies control by breaking down the complex task of channel navigation into manageable hierarchical steps.

AI summary
A channel zapping method is provided. The channel zapping method includes setting a channel group selected from among a plurality of channel groups classified by genre as a target for group zapping, and if a channel zapping command is input, performing channel zapping to a next channel in the channel group to which a current channel belongs, and if a group zapping command is input, performing channel zapping to a channel in another channel group included in the target for group zapping, and the another channel group is a channel group in a highest class or in a sub class which belongs to the highest class in the each genre.
