Electronic Program Guide Channel Subscription Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic program guide (EPG) systems do not effectively differentiate between subscribed and unsubscribed channels, leading to user frustration when trying to record programs on unsubscribed channels, as they display all channels by default, and users may only discover the lack of subscription after recording a program.
Innovation Solution
Implementing a method to classify channels as subscribed, unsubscribed, or unavailable, allowing users to distinguish between them through selective highlighting and organizing listings to prioritize subscribed channels, with the set-top box receiving and processing subscription data to differentiate channel listings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the EPG displays all channels including subscribed and unsubscribed channels, then the viewer can see all available programming options, but the viewer cannot easily distinguish which channels are subscribed and which are not, leading to frustration when attempting to record programs on unsubscribed channels
Solution Approach 1:
The patent applies local quality by differentiating the visual presentation of channels based on their subscription status. Subscribed channels are displayed with one set of attributes (e.g., normal highlighting) while unsubscribed channels are displayed with different attributes (e.g., dimmed appearance or distinct iconography). This allows the EPG to maintain completeness while providing localized visual differentiation that helps users quickly identify subscribable channels without requiring separate listings.
2Quantity of substance
If the EPG shows all channels to promote programs and encourage subscriptions, then more programming options are available to viewers, but users may only discover the lack of subscription after recording a program, causing annoyance
Solution Approach 1:
The patent implements preliminary action by checking subscription status before allowing program selection or recording. The system pre-validates whether a user has subscription to a channel before enabling them to select programs for recording. This preventive measure ensures users only attempt to record programs they have subscribed to, eliminating the frustration of discovering subscription issues after recording attempts and improving the reliability of the recording function.
3Ease of operation
If the EPG provides a favorites listing with selected channels, then the viewer can access frequently watched channels, but the viewer may not remember which channels are subscribed when viewing the full channel list
Solution Approach 1:
The patent applies feedback by providing real-time visual cues in the EPG that indicate subscription status for each channel. When users view the channel list, the system provides immediate visual feedback through distinct graphical indicators, color coding, or iconography that shows which channels are subscribed and which are not. This continuous feedback mechanism eliminates the need for users to remember subscription status and helps them quickly identify available channels without relying on favorites listings alone.
Data Source
AI summary
A method for providing an electronic program guide is disclosed. The method comprises receiving subscription data indicating channels for which a subscription exists; and displaying a list of available channels wherein currently unsubscribed channels and currently subscribed channels are distinguished from each other.
