Two-Way Working Systems TRIZ Cases
- Differential Queuing for Adaptive Video Frame Prioritization
Differential queuing prioritizes essential I-frames over P and B frames to maintain video quality during bandwidth-constrained trick-mode operations.
- Video Streaming Delay Calculation Using Server Buffer Feedback
Information processing apparatus calculates segment transmission delay using server buffer state data.
- Imaging Apparatus Acoustic Echo Cancellation for Video Calls
Dual acoustic echo cancellers remove TV sound and network feedback to maintain video call quality during simultaneous broadcasting playback.
- Video Stream Appropriateness Control via Automated Frame Analysis
Automated video stream analysis detects inappropriate visual content before transmission to protect participant privacy.
- IMS IPTV Personalized Advertisement Insertion via User Profile Segmentation
Segmenting users by profile attributes enables personalized advertisement insertion into common video streams without requiring separate broadcast channels.
- Conditional Bandwidth Re-negotiation for IPTV Channel Switching
Postponing bandwidth re-negotiation via a timer reduces processing delays and unnecessary signaling overhead during rapid IPTV channel switching.
- OS Service for Seamless Audio Video Device Switching
An OS service maps audio and video devices to a single handle, preventing session freezes during hardware transitions.
- Transparent Display Camera Nesting for Eye Contact
Nesting a camera behind a transparent OLED display resolves eye contact misalignment by subtracting reflected light interference from captured signals.
