An image information transmission system includes an image information transmitting apparatus (1), and an image information receiving apparatus. The image information transmitting apparatus (1) obtains primary-image transmission data, which is subjected to predetermined compression-coding (19, 20, 21) including bidirectionally predictive coding, for transmitting a moving image representing a primary image, and generates secondary-image transmission data for transmitting a secondary image to be displayed together with the primary image on a display screen. The primary-image transmission data and the secondary-image transmission data are transmitted to the image information receiving apparatus via a predetermined network communication link (26). Upon receipt of the primary-image transmission data and secondary-image transmission data, the image information receiving apparatus decodes the primary-image transmission data using a decoding scheme corresponding to the coding process, and decodes the secondary-image transmission data to generate a secondary-image video signal. The primary-image video signal and the secondary-image video signal are combined to display an image. |
