Broadcast Information Characterisation TRIZ Cases

Spatial rendering and decorrelated downmix signals create surround audio from mono or stereo-capable output environments.

Using H.264 for turbo streams while keeping MPEG-2 normal streams improves image quality and compression efficiency in digital broadcasting.

Combining object signals assigned to the same position cuts decoding and rendering complexity while preserving audio quality and spatial accuracy.

Automatic handover between ad hoc and infrastructure networks keeps streaming audio connected when the source moves out of earphone range.

Spatial information and filter-based rendering turn mono or stereo downmix signals into surround output without multi-channel playback hardware.

Conditional 3D rendering preserves spatial audio when multi-channel signals are reproduced through 2-channel outputs such as headphones.

A dual transport stream uses MPEG-2 for normal video and H.264 for turbo video to improve image quality and cut transmission load.

Automatic switching between ad hoc and infrastructure networks keeps wireless earphones streaming when direct range is lost.

Automatic seek logic steps through IBOC frequency channels and digital subchannels with one button, reducing user effort and control complexity.

A cancellation circuit senses shared-return voltage drops in headphones and injects compensating signals to preserve stereo channel separation.

Compensation parameters correct down-mix level attenuation so decoded multi-channel audio preserves channel balance and sound quality.

Compensation data and 3D rendering rebuild multi-channel spatial audio from down-mix signals for headphones and other limited-speaker playback.

Automatic switching between ad hoc and infrastructure wireless links keeps compact earphones connected for uninterrupted internet audio streaming.

An external audio-jack adapter keeps in-ear wireless earphones compact while switching between ad hoc and infrastructure networks for continuous streaming.

Compensation parameters correct down-mix level attenuation, helping decoded multi-channel audio preserve channel balance and sound quality.

H.264 compression on turbo streams cuts transmission load and channel use while preserving MPEG-2 normal streams in dual broadcasting.

Row-column twisted interleaving and shortened punctured LDPC improve OFDM signal efficiency, noise robustness, and channel capacity.

Voice-band removal, amplification, and level compensation improve channel separation and avoid center-heavy mono playback.

Compact left/right coherence side information cuts multi-channel audio data rate while preserving spatial quality and sound image fidelity.

Using H.264 for the turbo stream while keeping MPEG-2 for the normal stream improves image quality and cuts channel load in digital broadcasting.

A configurable recursive IIR filter cuts BTSC Difference-channel noise with one multiplier, preserving stereo audio quality at lower IC cost.
