Image transmission apparatus and method utilizing different transmission modes for transmitting moving image data and still image data
First Claim
1. An image transmission apparatus, comprising:
- a first memory, which stores moving image data;
a second memory, which stores still image data obtained from the moving image data; and
a digital interface adapted to transmit data to outside said image transmission apparatus using at least a first transmission mode and a second transmission mode, wherein said digital interface transmits the moving image data stored in said first memory using the first transmission mode, and transmits the still image data stored in said second memory using the second transmission mode, and wherein said digital interface transmits the still image data along with the moving image data in response to a user instruction.

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.

5. An image transmission method of an image transmission apparatus, said method comprising the steps of:
-
storing moving image data in a first memory;
storing still image data obtained from the moving image data in a second memory;
transmitting, to outside the image transmission apparatus, the moving image data stored in the first memory using a first transmission mode of a digital interface; and
transmitting, to outside the image transmission apparatus, the still image data stored in the second memory using a second transmission mode of the digital interface, wherein said transmitting steps transmit the still image data along with the moving image data in response to a user instruction. - View Dependent Claims (6, 7, 8)
