Integrated Mobile Communication and Broadcast Recording Trigger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Integrated mobile communication and broadcast program reproduction devices, such as cellular telephones, face challenges in allowing users to seamlessly switch between telephonic communication and broadcast program listening or watching, with limitations in automatic notification and recording of desired programs, as well as prioritization of broadcast content.
Innovation Solution
A cellular telephone with integrated modules for telephonic communication, broadcast reception, recording, and user alerting, featuring a microcontroller unit, user selected criterion detection, and speech recognition, enabling users to select and prioritize programs for recording or reproduction, and alerting them to start times of desired broadcasts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the integrated device is used for telephonic communication, then communication functionality is achieved, but broadcast program listening or watching is interrupted
Solution Approach 1:
The system automatically records broadcast programs before the user needs to use communication functions. The recording is initiated in advance based on predetermined criteria (program type, time, channel) so that when communication is needed, the program is already recorded and available for later viewing without interruption to the broadcast experience
Solution Approach 2:
A recording buffer serves as an intermediary between the broadcast receiver and the user. Instead of requiring direct simultaneous access to both broadcast and communication functions, the buffer stores the broadcast content, allowing the user to switch between communication and broadcast viewing without losing either function
2Ease of operation
If the user manually monitors and selects programs, then program prioritization is achieved, but user time and effort are increased
Solution Approach 1:
The system performs self-service by automatically monitoring broadcast programs and selecting which ones to record based on predetermined user-defined criteria. The microcontroller continuously scans broadcast information, compares it against stored criteria, and initiates recording automatically without requiring manual user intervention for each program decision
Solution Approach 2:
The system provides feedback to the user by alerting them when a program matching their criteria is detected. This feedback mechanism allows users to be notified of relevant programs without requiring continuous manual monitoring, reducing user time while maintaining program prioritization based on user preferences
3Extent of automation
If automatic recording is implemented, then program recording convenience is improved, but device complexity increases
Solution Approach 1:
The microcontroller serves multiple functions: it controls telephonic communication, manages broadcast reception, monitors program information, compares against criteria, and controls recording. By making the microcontroller multi-functional, the system achieves automatic recording capability without adding separate dedicated hardware for each function, thereby limiting the increase in overall device complexity

AI summary
A method for controlling operation of an integrated mobile communication and broadcast program reproduction device and of operating the device includes monitoring an occurrence of a trigger event at the device; and upon occurrence of the trigger event, recording a broadcast program signal received by the device. An integrated mobile communication and broadcast program reproduction device has a trigger event monitor and a broadcast program recorder for recording a broadcast program when a trigger event occurs. A trigger event may be receipt of an incoming call, the making of an outgoing call, the identification of predetermined content in a received program and the start of a predetermined program. Different trigger events may be prioritized. Recorded material may be reproduced, with broadcast material being received being recorded whilst previously recorded material is reproduced.
