Portable Media Device Tagging Broadcast Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in identifying and recording song information from radio broadcasts due to unreliable services and the need for remembering station details, with existing solutions being error-prone and inconvenient.
Innovation Solution
A portable media device and accessory system that detects and stores track-identifying metadata from radio broadcasts, allowing users to remotely control tuner functions and store track information for later retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users rely on existing song identification services (playlist lookup or sample matching), then they can identify songs from broadcasts, but the services are unreliable and error-prone
Solution Approach 1:
The system performs preliminary action by detecting and storing track-identifying metadata in advance during broadcast playback. The portable media device continuously monitors the broadcast stream for metadata tags and stores them locally, so when a user wants to identify a song, the information is already captured and ready for retrieval, eliminating the need for unreliable real-time matching services
Solution Approach 2:
The portable media device acts as an intermediary between the radio broadcast and the user. It receives the broadcast, extracts metadata tags, stores them locally, and provides retrieval functionality. This intermediary approach replaces unreliable external services with a trusted local system that guarantees information availability
2Loss of information
If users manually record song information during broadcasts, then they can capture track details, but they must remember station details and have ready access to pen or paper
Solution Approach 1:
The portable media device performs self-service by automatically detecting, capturing, and storing track-identifying metadata without user intervention. The system autonomously monitors the broadcast stream, extracts relevant information, and manages storage, freeing the user from manual recording tasks while ensuring accurate information capture
Solution Approach 2:
The system performs preliminary action by pre-capturing and storing metadata during broadcast playback. This advance preparation eliminates the need for users to manually record information during the broadcast, as everything is automatically documented and made available for later retrieval
3Loss of information
If the portable media device continuously monitors for metadata tags, then it can detect available track information, but it increases processing requirements and power consumption
Solution Approach 1:
The system implements periodic action by monitoring the broadcast stream for metadata tags at intervals rather than continuously processing all data. The device checks for the presence of tags periodically during playback, reducing processing load and power consumption while still effectively capturing available track information when it appears in the broadcast
Data Source
AI summary
Track-identifying information can be collected from a broadcast using a portable media device capable of receiving broadcast content in combination with an accessory capable of communicating user input to the portable media player. In some embodiments, the portable media player can detect the presence of track-identifying metadata (a “tag”) within a received broadcast and can alert the accessory when a tag is available for a currently-playing track. If the accessory instructs the portable media player to store the tag, the portable media player can do so and can alert the accessory when a tag for a track has been stored. In some embodiments, the accessory can also remotely control other broadcast-receiving functions of the portable media device, such as entering or exiting a broadcast-receiving mode of operation.
