Abstract: A communication transmitting apparatus is connected between IP telephones, and includes a tone storage unit configured to store tone data T that is unique, an adding unit configured to add the tone data T to the voice data V transmitted from the IP telephone to generate addition data, an arithmetic processing unit configured to convert a format of the addition data according to a prescribed specification to generate converted data including converted voice data Vc and tone data Tc, a separating unit configured to separate the tone data Tc from the converted data, and a comparison determination unit configured to determine that if the tone data T added to the voice data V before conversion performed by the arithmetic processing unit is different from the tone data Tc separated from the voice data Vc by the separating unit after the conversion, there is quality degradation in the voice data Vc.

Abstract: A communication transmission device is provided with an input sound level detection unit for dividing, per unit time, sound data of a predetermined period of time and converting the sound data into a bit string according to whether or not a sound level thereof exceeds a predetermined threshold value, an arithmetic processing unit for performing predetermined arithmetic processing on the sound data an output sound level detection unit for dividing, per the unit time, sound data of the predetermined period of time after the arithmetic processing and converting the sound data into a bit string according to whether or not a sound level thereof exceeds the predetermined threshold value, and a comparison determination unit for determining whether or not a sound failure has occurred on the basis of a predetermined logic by which the bit string before the arithmetic processing and the bit string after the arithmetic processing are compared.

Abstract: An information processing device includes: an identifier adding unit that adds identifiers including at least one type of valid identifier to each of a plurality of pieces of information; a plurality of input memories that hold the plurality of pieces of information and the identifiers, respectively; a plurality of output memories that hold a plurality of pieces of information processed by the processing unit and the identifiers added to the plurality of pieces of information, respectively; and an identifier inspecting and verifying unit that performs inspection and verification by comparing at least one identifier that becomes an inspecting and verifying target identifier among the identifiers to the valid identifier held in the input memory corresponding to the output memory that holds the inspecting and verifying target identifier.

Abstract: A communication transmission device (1) is provided with an input sound level detection unit (11) for dividing, per unit time, sound data (100) of a predetermined period of time and converting the sound data into a bit string (101) according to whether or not a sound level thereof exceeds a predetermined threshold value, an arithmetic processing unit (10) for performing predetermined arithmetic processing on the sound data (100), an output sound level detection unit (12) for dividing, per the unit time, sound data (100a) of the predetermined period of time after the arithmetic processing and converting the sound data into a bit string (101a) according to whether or not a sound level thereof exceeds the predetermined threshold value, and a comparison determination unit (13) for determining whether or not a sound failure has occurred on the basis of a predetermined logic by which the bit string (101) before the arithmetic processing and the bit string (101a) after the arithmetic processing are compared.

Abstract: Failure of a processing unit that processes a plurality of information pieces is discovered in a short time.

Abstract: Even when a processing unit that processes a plurality of pieces of information has a failure, significant information is prevented from being output erroneously. An information processing device 100 including a processing unit 1 that processes a plurality of pieces of information includes: an addition unit 2A that adds eigenvalues for input memories 20000 to 21023 to values of a plurality of pieces of information 40000 to 41023; a subtraction unit 2B that subtracts the eigenvalues from the plurality of pieces of added information 70000 to 71023 having no overlapping of the values, processed by the processing unit 1; output memories 30000 to 31023 that store the plurality of pieces of processed information 50000 to 51023; and a determination unit 3 that determines whether the value of each of the pieces of processed information 50000 to 51023 is within a predetermined range and outputs the processed information as invalid information when the value is outside the range.

Abstract: [Problem] Failure of a processing unit that processes a plurality of pieces of information is discovered in a short time.
