Satellite Broadcast Receiving TRIZ Cases
- Satellite Radio Ad Targeting via Mobile Location Relay
A satellite radio receiver uses a nearby mobile device to determine its current location for ad delivery.
- Satellite Bandwidth Efficiency via Overlapping Signal Combining
Combines source signals into overlapping frequencies using digital signal processors, separating interference to boost spectral efficiency.
- Dual FEC Decoders for Secondary Data in Single-Frequency Networks
Segmenting forward error correcting decoders enables regional data transmission in satellite audio systems while maintaining legacy receiver compatibility.
- Satellite Signal Combiner for Multi-Band Distribution
A combiner merges downconverted Ku and Ka intermediate frequency signals into a single delivery stream.
- Edge Cache System for Local Content Distribution
An edge cache system stores media content locally and transmits it via short-range wireless protocols to nearby consumer devices.
- SWM Device Frequency Drift Compensation for Satellite Broadcasting
Dynamic bandwidth adjustment in a single-wire multiswitch reduces excess spectrum while maintaining signal quality across varying transponder types.
- Primary Receiver Authorization for Multi-Device SDAR Subscriptions
A primary receiver manages multi-device satellite radio subscriptions by periodically verifying secondary receiver proximity to prevent unauthorized sharing.
- Shared Local Oscillator for Multi-Band Ka-band LNB
A shared local oscillator downconverts multiple satellite frequency bands into intermediate signals for distribution.
- Antenna Socket Authorization Control for Satellite One-Cable Systems
An antenna socket uses a control unit to check user IDs against stored configuration data before forwarding signals.
- Satellite LNB Power Supply Adaptive Load Waveform Control
Dynamic current sink circuit preserves 22 kHz waveform shape under high capacitive loads while minimizing average power consumption.
- Power Splitter Controller for DiSEqC Command Conflict Resolution
A power splitter controller unit manages DiSEqC commands via separate forwarding paths to prevent signal conflicts.
