Broadcast Transmission Systems TRIZ Cases
- Power Supply Control for Fast Surge Protector Reset
When a surge protector stays active too long in polarity-switched DC supplies, control logic raises polarity frequency to reset it faster and limit hardware damage.
- Sigma-Delta Modulator Notch Shaping for Wired Spectrum Efficiency
A modified noise transfer function adds a passband notch, letting wired links carry extra bandpass signals without disturbing the low-pass band.
- Decoder Buffer Depth Control for Predictable SFN Signal Delay
A controllable FIFO buffer adjusts decoder depth to align SFN signal timing, reducing overlap-area reception errors and delay uncertainty.
- MIMO OFDM Channel Feedback Using Capacity Threshold Updates
A receiver compares open- and closed-loop channel capacity and sends MIMO feedback only when the gain justifies bandwidth overhead.
- Dual-Cell Multicast Reception During Terminal Handover
Simultaneous source and target cell connections keep multicast broadcast data flowing during handover, reducing delay and reception loss.
- Access Network Handover Mapping for MBS Service Continuity
Pre-synchronized QoS flow to radio bearer mapping helps base stations maintain MBS packet continuity and reduce handover loss.
- 5G Bearer Mode Switching for Multicast and Broadcast Services
Dynamic switching between PTP and PTM bearers improves multicast and broadcast delivery while using 5G radio resources more efficiently.
- SMF Multicast Join Management for Relay and Remote UEs
Unified SMF handling of relay and remote UE join requests supports multicast service over UE-to-network relay with lower management complexity.
- PDCP State Initialization for Active NR Multicast Sessions
Network-signaled HFN and SN let a UE join active NR multicast sessions with synchronized PDCP state and reliable packet handling.
- CPE Theft Detection Using RF and DOCSIS Location Signals
RF broadcasts, DOCSIS telemetry, and pre-equalizer data are combined to flag unauthorized CPE use in nearby premises and cut network strain.
- Combined Multi-Waveform Signals for Shared-Band Receiver Discrimination
Multiple waveform signals are combined in one frequency band using power-level adjustment, enabling receiver separation without extra signaling.
- Audio Broadcast Template Adjustment Using Reception Feedback
Reception feedback lets a UE tune rebroadcast count and timing, cutting airtime use and power draw while maintaining audio packet delivery.
- Audio Device Bidirectional Data Over Shared Charging Line
Bidirectional data on the charger-to-broadcaster line enables simultaneous charging and communication while reducing power use and noise.
- Two-Way Smart Radio Music Control for Safety Communications
Geofenced rules and emergency detection adjust music volume or pause playback so frontline workers can hear safety communications.
- Two-Way Smart Radio Audio Synchronization via Geofencing
Geofenced facility rules adjust music playback and safety messages on two-way radios, helping frontline workers stay connected without extra devices.
- Two-Way Smart Radio Music Control Using Geofenced Worker Locations
Location-aware rules adjust music playback and safety messages as workers enter geofenced areas or approach nearby equipment.
