Abstract: When a call session is set over an IP network between a calling IP phone and a called IP phone at the start of a call, information on the quality of communication between a host IP phone and a recording server is exchanged to compare the quality of communication of the two IP phones in each of the calling IP phone and the called IP phone. For example, the called IP phone, or a host IP phone, with a higher quality of communication than the calling IP phone of a conversing party transmits call audio data to the recording server as recording data. Meanwhile, the calling IP phone, or a host IP phone, with a lower quality of communication than the called IP phone of a conversing party refrains from transmitting the call audio data to the recording server.

Abstract: An information processing system equipped with an information processing device, which includes multiple processors and a common parallel port (port), and a peripheral device, which includes a data classification means and multiple computing means. Each processor appends each processor identifier to a respective series of codes capable of expressing given data, thereby generating a writing unit capable of being written one time in the bus width of the port, and sequentially writes the writing unit to the port without performing exclusive control. A data classification means reads the writing units from the port sequentially and sequentially outputs the series of codes included in the writing unit to a computing means associated with the processor identifiers included in the writing unit. The computing means reconstructs the original data on the basis of the series of codes.

Abstract: To provide a video projector which improves visibility in response to changes in projection environment, a video projector has an initial level setter, a level adjuster, a projection display, an image capture, and a projection histogram calculator. The initial level setter performs a prescribed initial level setting on an input video signal and outputs an initial display signal. The level adjuster adjusts the level of the initial display signal on the basis of a projection image and outputs a display signal. The image capture captures the projection image projected on a projection surface by the projection display based on the display signal. The projection histogram calculator prepares a projection histogram for each color. The level adjuster adjusts the level of the initial display signal for each color on the basis of the projection histogram.
