Satellite Broadcast Receiving TRIZ Cases
- DVB-S Channel Scanning Method Using Adaptive Frequency Steps
A channel scanning method for DVB-S signals adjusts frequency steps to detect parameters efficiently.
- Satellite Gateway IP Packet Encoding for Multi-Dwelling Units
A satellite gateway repacks digital signals into IP packets with varying security levels for set-top boxes.
- DiSEqC Conflict Recognition via ODU Power-Off and Channel Change Commands
A DiSEqC conflict recognition method uses ODU_PowerOFF and ODU_ChannelChange commands to verify bus availability before transmission.
- Vehicle Satellite Receiver Ad Hoc Relay for Signal Blockage
A vehicle satellite receiver establishes ad hoc wireless connections with nearby receivers to obtain obstructed signals.
- Satellite Dish Reflective Gain Array for Terrestrial Signal Reception
A reflective gain array mounted behind a satellite dish increases digital radio frequency signal strength via rear reflection.
- Frequency Translation Module for Satellite Signal Distribution
A frequency translation module routes polarized satellite signals through existing coaxial infrastructure to support multiple receivers.
- Hierarchical Modulation Satellite Signal Separation
A satellite transmits high and low priority signals using orthogonal circular polarization patterns for efficient single frequency network delivery.
- VSAT Up-Converter Gain Calibration via Operating Frequency
A VSAT up-converting device sets maximum adjustable gain at a configuration location to transmit signals at the operating frequency.
- Optical LNB with Digital Channelizer for Satellite Signal Conversion
An optical low noise block converter uses a digital channelizer switch to select satellite content channels from input signals.
- Vehicular Audio Visual System Location-Aware Media Selection
A vehicular audio visual system uses positional information to determine receivable broadcast areas and restricts output modes accordingly.
- Satellite Signal Interruption Handling via Alternate Stream Switching
A television receiver monitors broadcast signal quality and obtains a lower-quality replacement stream from an alternate network source.
- Single Coaxial Cable Satellite Signal Distribution System
A single coaxial cable system delivers satellite signals to multiple receivers using a multiswitch with tuners and demodulators.
- Band Translation Switch for Multi-Satellite Signal Routing
A band translation switch routes multiple satellite signals through a single coaxial line using dedicated tuners.
- Rotating Wireless Antenna for Fixed Network Alignment
A motor rotates the antenna assembly within a closed cylinder to align directional beams, resolving interference and capacity constraints.
- Hybrid BWA MSS Emergency Alert Network Coverage
A hybrid network merges terrestrial broadband and satellite links to transmit emergency alerts via distinct radio frequency bands.
