Broadcast Reception References for Selective Program Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadcast recording devices record entire programs, including those the user does not wish to record, leading to unnecessary processes.
Innovation Solution
A broadcast reception device that acquires and stores program identification and storage-destination information, allowing selective recording and playback of desired programs from a server device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire broadcast program is recorded, then the user can access any part of the program, but unnecessary programs are also recorded consuming storage space
Solution Approach 1:
The patent extracts only the necessary program data for recording by identifying specific programs through program identification information (such as program IDs or titles) that the user designates. Instead of recording entire broadcast programs, the system extracts and records only the essential identification data, thereby reducing storage space consumption while maintaining the ability to access and retrieve desired programs.
Solution Approach 2:
The patent uses program identification information as a copy or reference marker rather than duplicating the entire program content. By storing only the program identification data and its association with storage destination information, the system creates a lightweight reference copy that enables program retrieval without consuming excessive storage space.
2Productivity
If program identification information is stored, then selective recording is enabled, but additional data management processes are required
Solution Approach 1:
The patent implements a self-service mechanism where the program identification information automatically contains or associates with the storage destination information. This self-contained data structure enables the system to automatically manage program retrieval without requiring complex external data management processes, thereby improving recording efficiency while minimizing operational complexity.
Solution Approach 2:
The patent merges program identification information with storage destination information into a unified data structure. By combining these two pieces of information, the system eliminates the need for separate data management processes, as the merged information directly enables both program identification and location retrieval in a single operational step.
3Quantity of substance
If the broadcast program is deleted after recording, then storage space is freed, but the program cannot be accessed later
Solution Approach 1:
The patent extracts and preserves only the essential program identification information after the broadcast program is deleted. By separating the program content from its identification data, the system frees storage space while maintaining the ability to access and retrieve the program through its identification marker, thereby resolving the contradiction between space availability and access capability.
Solution Approach 2:
The patent creates a persistent copy of the program identification information that survives program deletion. This identification copy serves as a permanent reference that enables program retrieval even after the original program content has been removed from storage, maintaining adaptability while optimizing storage space.
Data Source
AI summary
A broadcast reception device includes: a program recording execution unit that stores, into a recording-content storage area, program identification information for identifying a broadcast program, and storage-destination information for specifying a server device storing the broadcast program; a reception function execution unit that transmits the program identification information and the program storage-destination information to the server device specified from the program storage-destination information; and an output unit that outputs sound information and image information on the broadcast program transmitted from the server device.
