Digital Media Broadcasting TRIZ Cases
- Vehicle Message Display for Specific Driver-to-Driver Communication
A vehicle-mounted emissive display and voice-linked phone interface deliver specific road messages without hand gestures or distracted smartphone use.
- Object-Based Audio Packetization with Shared Headers
Shared header extraction groups audio ES packets by common information, cutting overhead and improving object-based audio transmission efficiency.
- Object-Based Audio Packetization With Reduced Header Overhead
By separating common and stream-specific header data, this case cuts packet overhead and improves object-based audio transmission efficiency.
- Object-Based Audio Multiplexing With Shared ES Headers
Filtering ESs by common information and using one multi-object header reduces packet overhead while preserving object-based audio delivery.
- Vehicle Radio Relay Control for Poor Analog Reception
When analog broadcast strength drops, a vehicle radio relays Internet radio as analog so nearby cars can keep listening in tunnels and weak-signal areas.
- Broadcast Radio Ad Bridge for Programmatic DSP Buying
This case uses a bridge bid and creative service to connect DSP bidding with scheduled terrestrial radio ad delivery.
- Digital Broadcast Receiver Silent State Detection and Service Switching
A digital broadcast receiver detects silent audio states and switches to an alternative signal with identical content.
- Circuit Board Shunt Element for Hardware Software Radio Demodulation
A circuit board shunt element directs downconverted signals to a processor or demodulator circuit.
- Dynamic Media Data Management for Aircraft Entertainment
A dynamic media management system ranks content items using usage log data to build a ranked media content data set.
- Multichannel Audio Broadcasting Data Stream Segmentation
Segments audio into independent streams to resolve the contradiction between high quality and legacy compatibility.
- Heartbeat System for ATSC 3.0 Broadcast Signaling
A heartbeat system implements a unicast signaling protocol to monitor device connectivity and signal quality in digital broadcast networks.
- Multicast Streaming for Broadcast Radio
A cloud-based service connects listeners to broadcast radio content via IP multicast streams.
- Dynamic Key Updates via Client State Verification
A digital rights management system verifies client device state to determine encryption key updates.
