Time-Shifted Content List Management in Image Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in efficiently searching for desired positions in time-shifted content recordings due to the need to remember both channel and shift time information, leading to increased time consumption as the number of time shifts grows, with existing methods only supporting simple searching through a progress bar.
Innovation Solution
An apparatus and method that generate a list of time-shifted contents when the time shift function is selected, allowing users to easily navigate and reproduce programs by displaying a list of time-shifted content details, including start and end times, titles, and source information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If users manually search for time-shifted content using only a progress bar, then the device complexity remains low, but the time required to locate desired positions increases significantly
Solution Approach 1:
The patent segments the continuous time-shifted content into discrete, organized list items with metadata (channel name, start time, end time, title). This segmentation allows users to quickly scan and identify desired content without manually scrubbing through the entire recording, directly reducing search time while maintaining manageable system complexity through structured data organization.
Solution Approach 2:
The patent adds a new dimension to the search interface by displaying time-shifted content as a structured list with multiple attributes (channel, time, title) rather than relying solely on the temporal progression of a progress bar. This dimensional expansion provides users with multiple cues for identifying content, significantly reducing search time without requiring complex hardware modifications.
2Adaptability or versatility
If the number of time shifts increases, then the time shift function becomes more useful, but the time required to search through recordings increases
Solution Approach 1:
The patent performs preliminary organization of time-shifted content into a structured list with metadata (channel names, time stamps, program titles) immediately when recordings are created or stored. This preliminary action ensures that even as the number of time shifts increases, users can quickly locate desired content through the pre-organized list rather than manually searching, thus maintaining versatility while controlling search time.
Solution Approach 2:
The patent provides visual feedback by displaying key information (channel name, time range, program title) for each time-shifted recording in the list. This feedback mechanism allows users to rapidly assess and identify desired content without playing or manually searching through recordings, enabling the system to handle increasing numbers of time shifts efficiently.
3Ease of operation
If users must remember channel and shift time information, then the system remains simple, but the ease of operation decreases
Solution Approach 1:
The patent enables the system to automatically generate and maintain a structured list of time-shifted content with all relevant metadata (channel names, time stamps, program titles). This self-service approach eliminates the need for users to manually remember or track recording information, significantly improving ease of operation. The system manages the information complexity internally through automated list generation and maintenance.
Data Source
AI summary
Provided are an apparatus and a method for controlling a stored image in an image display device. When a time shift function is selected by a user in the image display device having a storage function, information regarding a recording material for each time with respect to time-shifted contents, and exploration to a desired position is conveniently made. That is, a list of time-shifted contents is generated in cooperation with collectable program information and source (channel) information during broadcast, and information for maintenance and management of time shift. The generated list of the contents is displayed in the form of one of summary, a list, and an EPG. When one of the contents displayed on the EPG is selected by the user referring to the EPG, movement is made to a corresponding position, and a corresponding program is reproduced. Therefore, times consumed for searching for and exploring contents, and movement to a position of the contents can he reduced.
