摘要： A signaling unit of a display terminal establishes communication with a content server, video communication terminal, and PC server through a communication unit, and transmits/receives image data compressed by MPEG2, MPEG4, and JPEG. A media control unit switches compression schemes for decoding in a media processing unit on the basis of the received image data. The media processing unit performs decoding processing including inverse orthogonal transformation processing and dequantization processing in accordance with the switched compression scheme. At this time, a single processing circuit performs inverse orthogonal transformation processing and dequantization processing.

摘要： The communication unit transmits and receives a communication message. The authentication processor performs an authentication process for establishing the network connection by transmitting and receiving an authentication message to and from an authentication server through the communication unit. The encryption information generator generates an encryption key shared with the authentication server when the authentication process is successfully completed. The first message generator generates a first communication message instructing the destination device to acquire the encryption key from the authentication server. The second message generator generates a second communication message including data to be transmitted to the destination device. The communication unit transmits the first communication message to the destination device, encrypts the second communication message with the encryption key, and transmits an encrypted second communication message to the destination device.

摘要： The detecting unit detects a disconnection of communications that have been established with a display apparatus. When the disconnection of the communications is detected, the message generating unit generates a confirmation message that confirms whether the communications should be reestablished. The transmitting unit transmits the confirmation message to the display apparatus. The receiving unit receives a reply message that indicates whether the communications should be reestablished from the display apparatus. The main power supply controlling unit shuts down the main power supply when the reply message indicates that the communications should not be reestablished, or when no reply message is received.

摘要： When a processor, which transits from a first mode that causes a guest operating system to operate to a second mode that causes a virtual machine monitor managing the guest operating system to operate, when previously set transition condition is satisfied, transits to the second mode, a determining unit determines a cause or the transition. When it is determined that an execution of a process related to a completion of writing the image information in an image storage unit on the guest operating system is the cause, a detecting unit detects an updated portion representing an unmatched portion of the image information between before and after writing.
