A map data analysis unit refers to map data for a game in which a plurality of players compete in a three-dimensional space to extract positional information on each player. A feature parameter extraction unit extracts a feature parameter related to the game. A spectating area analysis unit analyzes one or more areas in a map that should be viewed by spectators, based on the positional information on each player and the feature parameter related to the game. A map data generation unit generates spectating map data by associating information indicating the area that should be viewed by spectators with the map data.

N (N&#x2265;2) time stretch units receive N channels of second image data which are obtained by dividing each line of first image data by N and are composed of a first number of bits. Each N time stretch unit arranges pixels of the N channels in the order of the pixels of the corresponding line of the first image data within a period which is obtained by stretching a one-line period of the second image data. The N time stretch units generate third image data including N lines of the first image data. N encoders encode each coding target pixel of the third image data outputted from the N time stretch units using a difference between the target pixel and a peripheral pixel to generate encoded data composed of a second number of bits which is smaller than the first number of bits.
