Abstract: The present invention provides a traffic accident detection device of detecting traffic accident that estimates a precise speed variation for a vehicle, and detects dangerous events similar to traffic accidents. A time series estimation unit (202) chronologically estimates a speed from a detected speed of a vehicle that a sensor unit (102) has detected, and acquires a first estimated value; and a reverse time series estimation unit (204) reverse chronologically estimates a speed from the detected speed, and acquires a second estimated value. An integration estimation unit (206) estimates the speed and the speed shift of the vehicle by defining the first estimated value as an integrated estimated value until a time when the distance between the first estimated value and the second estimated value is at maximum, and defining the second estimated value as the integrated estimated value at the time the distance is at maximum and thereafter.

Abstract: Information provisioning includes acquiring a plurality of audio and video elementary streams of which content is composed, and metadata related to the content. The metadata is divided into metadata processing units, in which the metadata is partially executable, corresponding to the plurality of audio and video elementary streams. A transport stream of a MPEG-2 system is generated by multiplexing an audio packetized elementary stream (PES), a video PES, and a metadata PES. The audio PES and the video PES are acquired by packetizing the plurality of audio and video elementary streams. The metadata PES is acquired by packetizing the metadata processing units. The point of the invention is characterized by transmitting metadata in PES format with the audio PES and the video PES.

Abstract: There is provided a scenario generation device capable of automatically generating a scenario for generating an animation of rich expression desired by a user even from a text created by the user who has no special knowledge about creation of animation. In the device, a scenario generation unit generates a scenario from a text inputted by the user, and a scenario edition unit edits a scenario with information recalled from words in the generated scenario by using external information acquired by an external information acquisition unit. That is, the scenario generation device recognizes information to be added to the text created by the user and adds information to the scenario by using external information acquired from a device owned by the user and a device existing in a communicable range. Thus, even the user has no special knowledge, the user can generate a scenario for realizing animation of expression near to the user's intention.
