A URL search apparatus is configured to perform a method for URL address search in a URL list. The URL search apparatus maintains a URL list, and the method for Uniform Resource Locator (URL) address search includes receiving a connection request containing URL address information from a user; identifying tables that are generated according to characters constituting URL address information in the URL list and lengths of character strings serving as URL address information in the URL list; and performing a URL search by checking whether the URL address information contained in the connection request is present in the URL list on the basis of the identified tables.

Method and apparatus for URL address search in URL list

A high-band speech encoding apparatus and a high-band speech decoding apparatus that can reproduce high quality sound even at a low bitrate when wideband speech encoding and decoding using a bandwidth extension function, and a high-band speech encoding and decoding method performed by the apparatuses. The high-band speech encoding apparatus includes: a first encoding unit encoding a high-band speech signal based on a structure in which a harmonic structure and a stochastic structure are combined, if the high-band speech signal has a harmonic component; and a second encoding unit encoding a high-band speech signal based on a stochastic structure if the high-band speech signal has no harmonic components. The high-band speech decoding apparatus includes: a first decoding unit decoding a high-band speech signal based on a combination of a harmonic structure and a stochastic structure using received first decoding information; a second decoding unit decoding the high-band speech signal based on a stochastic structure using received second decoding information; and a switch outputting one of the decoded high-band speech signals received from the first and second decoding units according to received mode selection information.
