摘要： The invention generates encoded data that properly conforms to pre-specified image quality and suppresses a large change in image quality. An encoding unit encodes pictures block by block according to a parameter. A distortion amount calculation unit calculates a picture distortion amount between a decoded picture and a picture before being encoded. A scene distortion amount calculation unit calculates a scene encoding distortion amount from the picture distortion amounts of a plurality of pictures having been encoded. A distortion bit rate conversion unit calculates a corrected bit rate by calculating a difference between a target distortion amount and the calculated scene encoding distortion amount, and multiplying the calculated difference by a coefficient. A target bit rate calculation unit calculates a bit rate for a picture subsequent to a picture of interest by adding a current target bit rate to the corrected bit rate, and sets it as the parameter.

摘要： An information terminal apparatus includes a memory and a processor. The memory stores information indicating a front operating system. The processor runs a first virtual machine that executes a first operating system. The processor runs a second virtual machine that executes a second operating system. The processor controls user interface of the information terminal apparatus by executing the front operating system. The processor detects, by referring to the information stored in the memory, that the front operating system is changed from the first operating system to the second operating system. The processor notifies, upon the detection, the first virtual machine of a first notification indicating that the user interface stops. The processor notifies, upon the detection, the second virtual machine of a second notification indicating that the user interface restarts.

摘要： A mobile terminal device receives information related to a push email service from a mail server, a calendar server, and a phone book server that provide the push email service via a wireless communication network. The mobile terminal device stores therein setting information that indicates whether the information related to the push email service is received at the time of the standby state. Furthermore, the mobile terminal device determines whether to shift the state of the mobile terminal device to a standby state. If the mobile terminal device determines that the mobile terminal device will shift its state to a standby state, the mobile terminal device transmits, on the basis of the stored setting information, a setting notification that instructs the stopping of the push email service to the mail server, the calendar server, and the phone book server.
