EPG-Reserved Recording List for Digital TV Timing Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in managing reserved recordings on digital TV systems due to incorrect PSIP information, leading to erroneous recordings and inconvenience in registering, modifying, or canceling reserved programs, especially when program start/end times change.
Innovation Solution
A broadcast receiver and method that utilize an Electronic Program Guide (EPG) to manage reserved recording information by receiving and storing reserved recording signals, creating an EPG-reserved recording list, and providing a user interface for registration, modification, and cancellation of reserved recordings, ensuring accurate display and management of user-selected programs with changed recording times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users rely on PSIP information for reserved recording management, then program information can be displayed on EPG, but incorrect PSIP information leads to erroneous recordings and inaccurate program timing
Solution Approach 1:
The patent introduces an EPG-reserved recording list as an intermediary data structure between PSIP information and the recording execution. This list serves as a verification layer that cross-checks program timing information, preventing erroneous recordings caused by incorrect PSIP data while maintaining accurate program scheduling
2Adaptability or versatility
If users manually select reserved time different from program start/end times on EPG, then recording can be activated at user-desired times, but the process becomes complex and inconvenient
Solution Approach 1:
The patent pre-generates and displays the EPG-reserved recording list showing all programs with their accurate start/end times before the user makes recording decisions. This preliminary presentation of information allows users to easily select desired recording times without complex manual adjustments, as the system has already organized the data in a user-friendly format
3Device complexity
If EPG internal module indicates reserved recording registration for only some programs, then system complexity is reduced, but users cannot recognize reserved recording status for all programs
Solution Approach 1:
The patent segments the reserved recording information display into two parts: the main EPG showing program information, and a separate EPG-reserved recording list showing all reserved recording statuses. This segmentation allows comprehensive information display without overcomplicating the main EPG module, as the additional information is presented in a dedicated separate interface
Data Source
AI summary
A broadcast receiver and a method for managing reserved recording information are disclosed. If a cell for a reserved recording list is added to an EPG (Electronic Program Guide), a user can easily check, modify, or delete all information associated with the reserved recording on the EPG, such that the user can conveniently manage the reserved recording information on the EPG. A method for managing reserved recording information of a broadcast receiver includes the steps of: a) receiving a reserved recording signal of a specific program; b) storing reserved recording information of the program on the basis of the reserved recording signal; and c) loading the stored reserved recording information, inserting the loaded reserved recording information into a pre-stored Electronic Program Guide (EPG), and creating an EPG-reserved recording list.
