  • Patent number: 9319699
    Abstract: Disclosed is a conversion apparatus including a decoding unit that decodes input encoded data into image data, and a size conversion unit that converts size of the image data based on a size conversion request received from outside and that expands/contracts, or splits/synthesizes motion vector or prediction mode of encoding parameters, received from the decoding unit, based upon a size conversion request, and an encoding unit that encodes image data after size conversion using the prediction mode or motion vector converted and transmits the resulting encoded image data via a transmission buffer to outside.

  • Patent number: 8369881
    Abstract: A PTT server includes a controlling unit, a receiving unit, a medium converting unit, and a transmitting unit. The controlling unit controls pieces of connection setting information less than the number of a plurality of PTT terminals having different specifications by complying them with the plurality of PTT terminals. The receiving unit receives a medium coded data from any one of the PTT terminals. The medium converting unit converts the medium coded data with a converting method on the basis of the connection setting information compliant with a PTT terminal for transmission destination to produce an output coded data. The transmitting unit transmits the output coded data to the PTT terminal for the transmission destination.

  • Publication number: 20100239001
    Abstract: A video streaming system includes a streaming server (101) which stores video streams and a transcoding device (102) which receives the video stream desired by a terminal (103), and analyzes the video stream to transcode only a video stream which falls within a range in which transcoding is required, when transmitting the video stream to the terminal (103) upon transcoding it into a video stream which can be transmitted from an arbitrary position designated by the terminal (103). The transcoding device (102) generates a playback start frame by a video transcoder (108) when the video stream reaches a playback start position, and analyzes subsequent frames by using the video transcoder (108). The transcoding device transcodes a video stream only when transcoding is required, while outputting a video stream without any change when transcoding is not required.
