Recorder Dubbing Function Batch Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recorder technologies require repetitive and time-consuming user operations for dubbing serial programs broadcast at the same time slot, necessitating individual setting for each episode, which is labor-intensive and prone to errors if a program is missed.
Innovation Solution
A recorder with a dubbing function that allows collective designation of recording and dubbing conditions for a series of programs broadcast at the same time slot, enabling batch processing and automatic handling of subsequent episodes with a single setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual dubbing instruction operations are performed for each program recorded on the hard disk, then the dubbing function can be implemented, but user effort and time increase significantly
Solution Approach 1:
The patent merges multiple individual dubbing operations into a single batch operation. The control unit automatically retrieves program information from the hard disk, displays it on the designation screen, and processes dubbing instructions for multiple programs simultaneously, eliminating the need for repeated manual operations for each program.
Solution Approach 2:
The system performs preliminary retrieval and organization of program information from the hard disk before the actual dubbing operation. By preparing the program list and displaying it in advance on the designation screen, the system enables users to issue a single batch dubbing instruction rather than performing individual operations for each program.
2Device complexity
If dubbing instructions are given only for recorded programs, then the system operates simply, but programs that are not recorded cannot be dubbed
Solution Approach 1:
The hard disk serves as an intermediary storage medium between the broadcast signal and the dubbing destination. The system records programs on the hard disk first, then uses the stored program information as a basis for batch dubbing operations, enabling both recorded and unrecorded programs to be processed through the same interface.
Solution Approach 2:
The dubbing designation screen and control unit are designed to handle multiple types of programs uniformly. Whether programs are newly recorded or previously stored, they are all retrieved and displayed in the same format, allowing the same batch dubbing mechanism to serve multiple functions and program types.
3Measurement precision
If manual searching is required for multiple broadcasts of serial programs, then individual program control is precise, but user effort and time increase
Solution Approach 1:
The system combines multiple serial program broadcasts into a single retrievable set from the hard disk. By automatically gathering program information for multiple broadcasts and displaying them together on the designation screen, the system allows users to select and dub entire series with a single operation rather than searching for each episode individually.
4Device complexity
If dubbing operations are performed one at a time, then system control is simple, but productivity decreases
Solution Approach 1:
The control unit performs preliminary retrieval and organization of multiple program information items from the hard disk before the actual dubbing process. This preparation step enables subsequent batch dubbing operations to proceed efficiently without requiring repeated control actions for each program, significantly improving productivity while maintaining simple control mechanisms.

AI summary
A recording condition and a dubbing condition of a desired program that is to be broadcast are designated by using a remote controller. These conditions are stored in the information storage unit. In accordance with the recording condition, a controller permits a tuner to receive a program for which unattended recording is designated, and to record the program on an HDD. When a DVD is set in a dubbing unit and the dubbing operation is instructed by using the remote controller, a recorded program for which a dubbing condition stored in the information storage unit is applied can be dubbed. Then, the information for this program is displayed on a monitor so as to confirm the program and the dubbing condition, and to examine or correct CM skip if the CM skip is included in the dubbing condition. Thereafter, the dubbing operation is performed.
