Abstract: The present invention provides a mobile terminal that can accomplish power saving of power consumption involved in decode processing, and that can shorten the time required until the video signal corresponding to the point is output to the display even if playback is executed at any desired point in moving image data. When a stream control section 19 detects a decode start trigger, a video decoding section 15 starts decode with a key frame of a video frames as a start point, the key frame being synchronized with an audio frame decoded by a sound decoding section 12. When the stream control section 19 detects display operation, a video output section 16 starts output with a first video signal as a start point, the first video signal being synchronized with a sound signal output by a sound output section 14.

Abstract: An object of the invention is to provide a communication terminal capable of causing an associated communication terminal to execute the function at the level required by the home terminal. A communication terminal of the invention is a video telephone 1 having a communication function and installing a common function to a function that a video telephone 2 installs, and includes a display image generation section 13A for generating data to execute the function that the video telephone 1 installs and data to execute the function that the video telephone 2 installs, and a data transmission section 11A for transmitting the data to execute the function that the video telephone 2 installs.

Abstract: The present invention provides a videophone terminal by which the emotions and impressions of a user can be transmitted to and easily understood by a co-communicant. When a user performs a predetermined operation or when an audio processor identifies a predetermined keyword in the speech of the user, a picture of a virtual character is modified, or a completely different picture is displayed. To modify the picture of the virtual character, the size of each part of the face or the whole face is changed, or a pattern expressing an emotion is added thereto. And when a pending mode is released, the virtual character is recovered and displayed on the screen while a melody is played. At the end of a video conversation, in accordance with the user's selection, a picture indicating that the virtual character disappears from the screen is displayed before disconnecting the line.
