    摘要: A content protection system prevents illegal key acquisition, without checking uniqueness of device keys. The content protection system includes a key data generation apparatus and a user terminal. The key data generation apparatus converts first key data, which is for using content, based on a predetermined conversion rule, thereby generating second key data, encrypts the second key data using a device key held by valid terminals, and outputs the encrypted key data. The user terminal obtains the encrypted key data, decrypts the encrypted key data using a device key held by the user terminal, thereby generating second key data, converts the second key data based on a re-conversion rule corresponding to the conversion rule, thereby generating the first key data, and uses the content with use of the generated first key data.

    摘要: A fixing device for thermally fixing an unfixed image formed on a recording sheet by passing the recording sheet through a fixing nip. The fixing device has: a heat-generating endless belt having, on a circumferential surface thereof, a sheet passing area through which the recording sheet passes; a first pressure member disposed inside a running path of the endless belt; and a second pressure member disposed to press the endless belt against the first pressure member from outside the running path to form the fixing nip. The endless belt includes: a resistive heat layer that generates heat upon receiving electric current; and a pair of electrode layers that receive electric current. The electrode layers flank the sheet passing area. The resistive heat layer is in contact with the electrode layers at a different one of end faces opposing each other in a width direction of the resistive heat layer.

    摘要: A broadcast receiving device includes a table storage component, a viewing control acquisition component, a first determination component, a table acquisition component and a table updating component. The first determination component determines whether or not one of a following is satisfied: a column determination condition that a column number of a program viewing control information is greater than a first specific number of a first viewing control table, and a row determination condition that a row number of the program viewing control information is greater than a second specific number of the first viewing control table. The table acquisition component acquires a second viewing control table via a television broadcast when the first determination component determines that one of the column determination condition and the row determination condition is satisfied. The table updating component replaces the first viewing control table with the second viewing control table.
