Two-Way Working Systems TRIZ Cases
- CATV Network Frequency Response Measurement via Low-Amplitude Test Signals
Low-amplitude test signals injected during allocated time slots measure CATV frequency response while preventing interference with normal digital transmission.
- Multicast Control via Layer 2 Switching for IPTV
Layer 2 switches perform IGMP snooping to forward joins and leaves, reducing system complexity and channel-change latency.
- Remote Media Format Transcoder for Seamless Content Sharing
A remote media format transcoder converts program data between incompatible formats for seamless content sharing.
- Wireless Hotspot Signal Quality Switching for Video Delivery
A wireless hotspot system switches between cellular and ATSC transmissions based on signal quality assessments.
- Remote Video Device Controller via IP Network Intermediary
A control server translates local inputs into device-specific commands for remote video devices over IP networks.
- Video Sampling Resolution Matching for Distortion-Free Communication
A transmitting terminal selects camera resolution based on receiving terminal configuration to sample video content at the matching aspect ratio.
