Broadcast Transmission Systems TRIZ Cases
- MBSFN Zone Sub-Zoning for Wireless Data Transmission
A wireless data transmission method divides MBSFN zones into sub-zones to enable superposed multicast and unicast service delivery.
- Digital Up-Conversion Module for Cable Modem Signal Interference
A digital up-conversion module block up-converts multiple channels using a digital modulator and integrated DAC.
- Spontaneous Event Context Detection via Media Flow Analysis
A mobile system detects spontaneous event boundaries by analyzing shared media content flow rates between group members.
- Iterative Antenna Pattern Determination for Phase Offset Compensation
An iterative method determines preferred transmit and receive antenna patterns by adjusting coefficients based on received reference signals.
- LTE TDD Subframe Configuration for P2P Communication
Configures MBSFN subframes and guard periods to allocate dedicated symbols for peer-to-peer communication in LTE TDD systems.
- Partial State Block Acknowledgment for Multicast Retries
Reserving channel access prevents collisions during multicast retransmissions, improving reliability without sacrificing transmission efficiency.
- Broadcast Parameter Determination via Channel Quality Classification
A processing node classifies geographic areas using channel quality indicators to determine transmission schemes for wireless devices.
- Multicast Tree Switchover via Forwarding Plane Thresholds
Forwarding plane byte counters detect traffic thresholds to trigger multicast tree switchover, reducing control plane messaging overhead.
- Peer-to-Peer Subscriber Registration Indexing for Frequency Alignment
A numerical registration index resolves race conditions during frequency alignment by establishing a common reference for the last valid subscriber affiliation.
- Motion Sensor Data Resolving Media Source Detection Ambiguities
Motion sensor data from accelerometer tags identifies active media sources, resolving simulcast monitoring ambiguities without complex audio signal acquisition.
- Jackshaft Door Operator Remote Monitoring Delay Mechanism
A programmable control module generates light or sound commands before moving a garage door.
- Multicast System Dynamic Mode Adaptation for Wireless Reliability
A multicast processing module identifies data initiators to receive data in multicast or promiscuous modes.
- 6LoWPAN over USSD Signaling for IPv6 M2M Connectivity
A 6LoWPAN adaptation mechanism transmits IPv6 frames over GSM USSD signaling channels to enable IP connectivity.
- Digital Content Prefetching for Seamless Radio Station Switching
Prefetching digital content via persistent connections eliminates buffering delays during radio station switching.
- Imperceptible SIP Invites for Group Call Quorum Management
An imperceptible Session Initiation Protocol invite gathers participant acceptance without triggering user alerts.
- Unified Messaging Client for Multi-Transport Message Handling
A unified messaging client selects appropriate transports for destination addresses to compose and send messages across multiple protocols.
- Wireless Lighting Device Selection via Link Quality
A wireless remote device selects lighting nodes by broadcasting messages and receiving unicast responses filtered by communication link quality.
