Digital Broadcast Recorder Automatic Program Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital broadcast recorders require users to manually edit and search through recorded programs, which is inconvenient due to the difficulty in identifying desired recordings amidst unrelated content during time shift or instant recording.
Innovation Solution
A digital broadcast recorder that analyzes and edits broadcast programs using Electronic Program Guide (EPG) data for automatic storage and management as separate units, allowing for efficient identification and retrieval of recorded content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual editing and searching methods are used for recorded programs, then users can identify desired recordings, but the process is inconvenient and time-consuming due to difficulty in identifying desired content amidst unrelated content
Solution Approach 1:
The system performs preliminary actions by automatically analyzing broadcast content and pre-organizing recorded programs into categories and tags before the user needs to search. The EPG data is processed in advance to create structured metadata, including program titles, genres, and key content identifiers, so that when users search for content, the work of organization has already been completed, significantly reducing search time and improving ease of operation.
Solution Approach 2:
The patent introduces an intermediary system consisting of automatic analysis algorithms and EPG data processing mechanisms that act as a mediator between the raw recorded content and the user. This intermediary layer automatically extracts meaningful information from broadcast content, organizes it into structured formats, and presents it to users in an easily navigable manner, eliminating the need for users to manually sort through unrelated content.
2Adaptability or versatility
If time shift recording is used to store broadcast streams, then users can view programs during phone calls or interruptions, but the recorded content includes unrelated programs that complicate content identification
Solution Approach 1:
The patent applies segmentation by dividing the continuous time-shift recorded content into distinct program segments based on EPG data boundaries. Each segment is tagged with program-specific metadata including title, start time, end time, and genre. This segmentation allows users to easily identify and navigate to desired programs within the time-shift recording without being overwhelmed by unrelated content, preserving the flexibility of time-shift recording while solving the information loss problem.
Solution Approach 2:
The system uses visual differentiation (analogous to color changes) by displaying different visual indicators or highlights for different program types or importance levels in the recorded content. Programs that match user preferences or are currently playing are highlighted or marked with distinctive visual cues, making it easy for users to identify desired content amidst the time-shift recording buffer.
3Productivity
If instant recording is used to capture current broadcast programs, then users can record programs of interest, but the recorded content may include programs before or after the desired program that require editing
Solution Approach 1:
The system performs preliminary organization of instant recording content by automatically detecting program boundaries using EPG data and analyzing broadcast stream metadata during the recording process. This preliminary action creates a structured index of the recorded content with program titles, timestamps, and categories before the user needs to manage or search the content, reducing the complexity of recording management while maintaining fast recording speed.
Solution Approach 2:
The patent implements self-service by enabling the recording system to automatically manage its own content organization without user intervention. The system autonomously analyzes broadcast content, identifies program boundaries, extracts EPG data, and organizes recorded programs into categories and playlists based on user preferences. This self-service capability eliminates the need for manual editing and simplifies recording management complexity while maintaining high productivity.
Data Source
AI summary
A digital broadcast recorder and a recording method thereof are disclosed. The recording method of a digital broadcast recorder having a storage medium, includes analyzing transmitted channel data and program data, and editing a broadcast program for the unit of program referring to the analyzed channel data and program data during recording of the broadcast program to store and manage the edited broadcast program in the storage medium. Therefore, it is possible to enhance a user's convenience when searching for and reproducing a recorded program.
