Solution Overview

Problem

Current radio receivers lack the ability to seamlessly switch between broadcast channels and create composite streams from multiple sources, leading to limitations in receiving and playing signals from various channels efficiently.

Innovation Solution

A radio receiver system that can automatically attempt to receive a selected broadcast stream on alternative channels if not available on the initial channel, and allows users to create composite streams from multiple broadcast sources, using a computer-readable medium and open interface merge replication to synchronize data across databases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a radio receiver is designed to receive only a single broadcast channel at a time, then the device complexity is low, but the adaptability and versatility are limited

Engineering Contradiction:
Improveability to receive broadcast streams on alternative channelsVSAvoidreceiver complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The receiver pre-stores multiple broadcast channels and their signal characteristics in memory before operation. When a selected broadcast stream is not receivable on the selected channel, the receiver can quickly access and switch to alternative pre-stored channels without complex real-time searching, thus improving adaptability while maintaining relatively simple device structure

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The receiver implements dynamic channel switching capability where the broadcast channel can be changed in real-time based on reception quality. The system monitors signal strength and automatically transitions between pre-stored channels to maintain optimal reception, making the receiver adaptable to varying broadcast conditions without requiring complex infrastructure

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a radio receiver attempts to receive multiple broadcast streams simultaneously on different channels, then the adaptability improves, but the device complexity and processing requirements increase

Engineering Contradiction:
Improveability to create composite streams from multiple sourcesVSAvoidreceiver complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The receiver divides the composite stream creation process into separate functional modules: one module receives and processes individual broadcast streams, another module retrieves related information from stored databases, and a third module synthesizes the composite stream by combining selected portions from multiple sources. This segmentation allows complex multi-stream processing while maintaining manageable device architecture

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces databases as intermediary storage elements that hold broadcast stream data and related information separately. The receiver queries these databases to retrieve specific portions of broadcast streams for composite stream creation, rather than processing all streams simultaneously in real-time. This intermediary approach reduces processing complexity while enabling versatile composite stream generation

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If broadcast stream data is stored in databases for later retrieval and composite stream creation, then the productivity and user experience improve, but the loss of time for data synchronization and database updates increases

Engineering Contradiction:
Improveefficiency of signal reception and playbackVSAvoidtime for data synchronization
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary data acquisition and storage by capturing broadcast streams and storing them in databases in advance of when they are needed for composite stream creation. This pre-storing approach eliminates the need for real-time data retrieval during playback, significantly improving productivity while the initial storage time is amortized over multiple future uses of the stored data

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates copies of broadcast stream data and stores them in databases for later retrieval. Instead of repeatedly accessing the original broadcast sources during composite stream creation, the receiver uses stored copies, which eliminates time-consuming real-time data fetching and synchronization delays, thereby improving playback efficiency and user experience

Inventive Principle:
Principle #26Copying

AI summary

A radio receiver may comprise a receiver adaptable for receiving a plurality of broadcast streams over a plurality of broadcast channels, wherein the receiver will attempt to receive a selected broadcast stream on a selected broadcast channel, and if the selected broadcast stream is not receivable on the selected broadcast channel, the receiver will attempt to receive the selected broadcast stream on an alternative broadcast channel. A computer readable medium may allow a user of a receiver to create a composite stream comprising at least one portion selected from each of at least two of a plurality of broadcast streams. A method of open interface merge replication may involve comparing data between first and second databases, and if a conflict exists, updating one of the first and second databases with at least a portion of data from the other of the first and second databases to resolve the conflict.
