Latest Patents

One of his latest patents is the "Embedded code-excited linear prediction speech coding and decoding apparatus and method." This invention provides an embedded code-excited linear prediction speech coding and decoding apparatus that can adapt to changes in the capacity of speech transmission channels. It models an error signal not coded at a core speech coder based on the transmission rate in either a multiple pulse search mode or gain compensation mode. The apparatus includes a core speech coding unit for coding an input speech signal with spectral envelope and an excitation signal, a transmission rate determination unit for allocating additional bits based on the transmission channel's capacity, and an embedded excitation signal coding unit for coding a residual excitation signal based on the number of allowed bits.

Another notable patent is the "Caller identification method, and billing system and method using the same in internet telephony." This system provides a caller identifier that reflects the actual user rather than relying on the conventional telephone number associated with a caller terminal. The billing method allows for user authentication through a certification authority for a caller identifier that is independent of the caller terminal. The method includes receiving authentication information from a caller terminal, verifying this information, and setting up the call if the authentication information matches the certificate.
