Abstract:
1. A multiplexing device that multiplexes a plurality of pieces of data, comprising: a data conversion unit that segments or concatenates at least one of the plurality of pieces of data to output converted data that is not larger than a predetermined limited size and is delimited into a predetermined data unit; a plurality of adaptation units comprising an image data adaptation unit arranged in parallel that adapts the plurality of pieces of data and the converted data with an adaptation layer; and a multiplexing layer unit that multiplexes the adapted data to output multiplexed data, wherein when the at least one of the plurality of pieces of data is image data and is not terminated as a predetermined data unit and is larger than the predetermined limited size, the data conversion unit segments the at least one of the plurality of pieces of image data by the predetermined limited size to output the converted data and when the size of remaining data is smaller than the predetermined limited size, the data conversion unit holds the remaining data without outputting the remaining data, wherein when the at least one of the plurality of pieces of data is the image data and is not terminated as the predetermined data unit and is smaller than the predetermined limited size, the data conversion unit holds the at least one of the plurality of pieces of image data as remaining data without outputting the remaining data, wherein when the at least one of the plurality of pieces of data is larger than a preset first maximum size, the plurality of adaptation units trim the at least one of the plurality of pieces of data by the first maximum size and output the trimmed data as an adaptation layer function, and wherein when a third maximum size, obtained by subtracting a size of adapted data from other than the image data adaptation unit of the plurality of adaptation units and a size of a header attached by the multiplexing layer unit from a second maximum size of the output data of the multiplexing layer unit, is equal to or less than the first maximum size, the image data adaptation unit trims the at least one of the plurality of pieces of data by the third maximum size as an adaptation layer function.
