Information processing apparatus, control method of the same, and storage medium

An information processing apparatus for transmitting, to a client apparatus, image data of one or a plurality of partial areas of a plurality of partial areas forming an image, comprising:

• an accepting unit configured to accept designation of a region of interest in the image from the client apparatus;
• an establishing unit configured to establish a connection as a logical communication path to the client apparatus, and establish, as a plurality of streams based on the connection to the client apparatus, a plurality of streams including a stream for receiving image data of the region of interest, and a stream for receiving image data of a partial area other than the region of interest, such that the stream for receiving the image data of the region of interest and the stream for receiving the image data of the partial area other than the region of interest are different from each other;
• a control unit configured to control the plurality of streams such that the image data of the region of interest is obtained preferentially to the partial area;
• and
• a transmitting unit configured to transmit image data to the client apparatus by using the plurality of streams controlled by the control unit.

A control method of an information processing apparatus for receiving, from a server apparatus, image data of one or a plurality of partial areas of a plurality of partial areas forming an image, comprising:

• determining a region of interest in the image;
• establishing a connection as a logical communication path to the server apparatus, and establishing, as a plurality of streams based on the connection to the server apparatus, a plurality of streams including a stream for receiving image data of the region of interest, and a stream for receiving image data of a partial area other than the region of interest, such that the stream for receiving the image data of the region of interest and the stream for receiving the image data of the partial area other than the region of interest are different from each other;
• and
• receiving image data from the server apparatus by using the plurality of streams controlled such that the image data of the region of interest is obtained preferentially to the partial area.
