  • Patent number: 8677001
    Abstract: 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.
