The audio/video network system includes a central processor that controls a plurality of audio/video sources (e.g., DVD players, cable TV receivers, etc.). Output from audio/video sources is encoded by audio/video encoders for transmission via a local area network. Classroom control hubs within each classroom recognize data packets addressed with the bit-wise addressing scheme and in combination with a video decoder, recover the encoded audio/video signal for presentation within the classroom, such as by a video projector and classroom speakers. Transmitting audio/video information in UDP packets addressed with the bit-wise addressing scheme enables near simultaneous presentation of audio and video programs throughout the educational facility. The system can also manage traditional school bells and public address functions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Campus audio-visual control and communication system","description":"A method and system for distributing audio, visual, data, annunciator and other information within an educational facility utilizes a bit-wise addressing scheme to route UDP message packets to individ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8520674","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
