Latest Patents

Katoh holds two notable patents that showcase his expertise. The first is a patent for a **Transmission system and method thereof**. This invention introduces a frame disassembly unit designed to receive MAC frames, enabling the identification of destination addresses and tags. Additionally, it includes an information retrieval unit that accesses a VLAN information database to match tags and ports with destination addresses. The system can determine the type of MAC frame—be it unicast, multicast, or broadcast—and incorporates controls to ensure appropriate transmission based on the frame type.

The second patent is for a **Voice communication system and its method**. This invention addresses the needs of voice over IP (VoIP) terminals, particularly in handling incoming multicast calls. Upon receiving such a call, a subscriber line interface circuit (SLIC) emits a ringing signal to activate a loudspeaker interface. This system ensures that even if the user does not respond, the voice output will commence, thereby enhancing the communication experience. Compressed voice data is extracted from received IP packets and converted into voice signals through a digital signal processor (DSP) and a CODEC.
