    摘要: A decoding/outputting section decodes encoded data. A decoding error determination section determines presence/absence of a decoding error each time the encoded data is decoded by the decoding/outputting section. A storing section stores determination results in a chronological order. A determination section determines whether the number of determination results indicating “decoding error”, among latest N consecutive ones of the determination results stored in the storing section, is greater than or equal to M. A control section has a normal mode in which the control section limits an output of the decoding/outputting section based on a determination and an error mode in which the control section unconditionally limits an output of the decoding/outputting section irrespective of the determination result. The control section transitions to the error mode when the determination section determines that the number of determination results indicating “decoding error” is greater than or equal to M.

    摘要: A reproduction speed conversion apparatus includes an audio decoding section; an audio reproduction speed conversion section; a video reproduction speed conversion section; and a video decoding section. The video reproduction speed conversion section determines whether reproduction speed conversion corresponding to a requested level is possible or not. When the reproduction speed conversion is determined to be possible, the video reproduction speed conversion section performs reproduction speed conversion corresponding to the requested level. When the reproduction speed conversion corresponding to the requested level is determined to be impossible, the video reproduction speed conversion section performs reproduction speed conversion corresponding to a prescribed level lower than the requested level, and outputs a second reproduction speed signal representing the prescribed level to the audio reproduction speed conversion section. The audio reproduction speed conversion section performs reproduction speed conversion corresponding to the prescribed level in response to the second reproduction speed signal.

    摘要: An information processing method has a mechanism wherein mutual verification is performed between tasks and a computer operating system at the time of activating tasks, thereby judging the validity of tasks. The operating system evaluates a key which the task holds at the time of requesting service of the operating system, and permits execution of services only in the event that the operating system itself has the same key. A mail transmitting task specifies a mail ID and address to a mail body, management information is written by the operating system to a secure memory queue list based on the security level of the mail transmitting task and the security level of a transmitting function, and contents wherein mail transmission contents are enciphered with the mail ID, address value of management information, and address value of the mail body, as a key, are written to a buffer. The operating system deciphers the contents of the buffer wherein the received contents exist, with the mail ID, address value of management information, and address value of the mail body, as a key, based on the security level of the mail receiving task and the security level of a receiving function, and copies this onto a buffer on the mail receiving task.
