When a SETUP message of RTSP is received, a port number having the same number of digits as a client port number notified by a client is assigned from a port number pool, and is registered in an NAPT table. The SETUP message is rewritten with the port number."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gateway device and port number assignment method","description":"When streaming transfer of voice or image is performed using a real time streaming protocol (RTSP), streaming transfer of a high bit rate is enabled even in an environment of using network address por","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8462800","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.
