Cue Playback Skip Time Calculation for Recorded Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Viewers face inconvenience when trying to watch recorded content as they need to wait for the program to start, which can be time-consuming and cumbersome.
Innovation Solution
An information processing apparatus and method that determine if a recorded content is suitable for cue playback by checking its recording start time, allowing viewers to skip to the correct playback time, thereby reducing waiting time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If recording starts before program start time to capture complete content, then recording completeness is improved, but playback waiting time increases
Solution Approach 1:
The system performs preliminary recording before the actual program start time to capture complete content including commercials and transitions. The recording start time is set earlier than the program start time, storing this offset information for later playback to enable skipping of unnecessary preliminary content.
Solution Approach 2:
The system calculates and implements time skipping during playback based on the difference between recording start time and program start time. This allows the playback to rush through the unnecessary preliminary recording period and start displaying the actual program content immediately, eliminating viewer waiting time.
2Reliability
If recording includes all content from recording start time, then content completeness is improved, but playback efficiency deteriorates
Solution Approach 1:
The system extracts and separates the useful program content from the unnecessary preliminary recording content. By calculating the time difference between recording start and program start, the system extracts only the relevant playback duration, excluding the redundant initial period from the playback process.
Solution Approach 2:
The system changes the playback parameter (playback start time) based on the recording metadata. Instead of playing back from recording start time, the playback starts from program start time by adjusting the time offset, thereby improving playback efficiency while maintaining content completeness.
3Device complexity
If automatic playback starts from recording beginning, then simplicity is improved, but user convenience deteriorates
Solution Approach 1:
The system automatically determines and applies the correct playback start time without user intervention. By reading the program start time from recording metadata and automatically calculating the appropriate offset, the system serves itself to provide convenient playback, eliminating the need for users to manually adjust playback timing.

AI summary
In an information processing apparatus, a cue playback decision unit 610 determines, based on recording information acquired from a recording information storage unit in which a recorded content having a program recorded and the recording information of the recorded content are associated with each other, whether or not a recorded content of a playback target is a recorded content whose recording is started prior to starting time of the program and which is to be played back by cue playback. A time confirmation unit 612 acquires, when it is determined that the recorded content is a recorded content to be played back by cue playback, recording starting time included in the recording information of the recorded content of the playback target from the recording information storage unit. A skip time acquisition unit 614 determines, based on the number of seconds of the recording starting time acquired by the time confirmation unit 612, a period of time to be skipped upon cue playback of the recorded content of the playback target.
