Data communication apparatus, method and system and programs for data communication process stored in computer readable storage medium
First Claim
1. A transmission apparatus for transmitting compressed still image data that is compressed and encoded by an encoding method or non-compressed still image data that is not compressed and encoded by the encoding method to a printer, said transmission apparatus comprising:
- a detection unit adapted to detect whether or not the printer has a function for decoding the compressed still image data; and
a communication unit adapted to transmit the compressed still image data to the printer, if the printer has the function, and to transmit the non-compressed still image data to the printer, if the printer does not have the function.

Abstract
In a data communication apparatus for encoding information data by using a predetermined encoding method, encoded information data is transmitted isochronously with a predetermined communication cycle when the encoding method corresponds to a decoding method at an object node apparatus and non-encoded information data is transmitted asynchronously with the communication cycle when the encoding method does not correspond to the decoding method at the object node apparatus. It is therefore possible to perform an encoding process for the information data to be transmitted, in accordance with a decoding performance at the object node apparatus, to improve a communication efficiency, and to reduce a capacity of a memory used for communications.

7. A transmission method of transmitting compressed still image data that is compressed and encoded by an encoding method or non-compressed still image data that is not compressed and encoded by the encoding method to a printer, said method comprising:
-
a detection step, of detecting whether or not the printer has a function for decoding the compressed still image data; and
a transmission step, of transmitting the compressed still image data to the printer, if the printer has the function, and transmitting the non-compressed still image data to the printer, if the printer does not have the function. - View Dependent Claims (8, 9, 10, 11, 12)
