The content transmission request from the user terminal 100 includes terminal model information for specifying the model of the user terminal 100. The data transmission / reception unit 24 acquires the terminal model information of the user terminal 100 from the content transmission request received from the user terminal 100 and inputs it to the terminal specification acquisition unit 28. The terminal specification acquisition unit 28 acquires terminal specification information from the terminal specification DB 26 based on the terminal model information.

  The terminal specification database (terminal specification DB) 26 stores specification information indicating content display capability for each model of the user terminal 100. FIG. 2 is a table showing an example of specification information stored in the terminal specification DB 26. As shown in FIG. 2, in the content display capability information table, the display size, the number of displayable characters, and the memory capacity are recorded for each model of the user terminal 100 (mobile phone 1, 2,...). Here, the display size is the number of pixels in the vertical and horizontal directions of the display screen of the user terminal 100, and is represented in a format of (vertical pixel number) × (horizontal pixel number) in FIG. The number of characters that can be displayed is the number of characters that can be displayed on the display screen of the user terminal 100, and is represented in the form of (number of vertical characters, number of displayable lines) × (number of horizontal characters) in FIG.

  The transmission content determination unit 20 determines the number of items to be displayed in the content to be transmitted (the number of display items) based on the specification information acquired by the terminal specification acquisition unit 28. For example, the transmission content determination unit 20 sets the number of display items on one screen of the content to be transmitted based on the number of displayable rows. Then, the transmission content determination unit 20 outputs information on the set number of display items to the data conversion unit 22.
