A data processing apparatus edits an actual data portion excluding a header from data transmitted by streaming transmission from a first information processing apparatus after start of streaming transmission. The data processing apparatus transmits edited actual data portion and header to a second information processing apparatus by streaming transmission. The second information processing apparatus reproduces the voice data or the animation data transmitted by streaming transmission. The actual data portion is edited so that the voice data or the animation data to be transmitted may be reproducible in the second information processing apparatus, and so that a program may become unexecutable even if it would be transmitted to the second information processing apparatus. Even if the voice data or the animation data transmitted from the first information processing apparatus by streaming transmission would be deteriorated, an executable virus program does not transmitted to the second information processing apparatus, thereby that makes it possible to realize the streaming transmission method which can realize simple and high security.

A sensor event controller dynamically switches a destination to which sensor event data are to be notified, according to a service application program (AP) that a user is using, and notifies sensor event data in compliance with an interface of the service AP as the notification destination. An information collection part stores information for identification of a service AP used on a browser and header information transmitted/received between the browser and the service AP in a collected data storage part. Upon receiving sensor event data, a data-notified application determination part decides that the service AP used on the browser is a service AP as the notification destination, by referring to the collected data storage part. A notified data conversion part converts the sensor event data so that the data are compliant with an input interface of the service AP as the notification destination, and transmits a processing request to the service AP as the notification destination, the processing request being generated by adding the header information to the converted sensor event data.
