Method of controlling transmission rate in streaming, and system thereof

A method of controlling a transmission rate in streaming of an image transmission device, the method comprising the steps of:

• streaming out, by the image transmission device, image information with a first transmission rate to a system;
• receiving, by the image transmission device, feedback information from the system;
• and
• streaming out, by the image transmission device, subsequent image information with a second transmission rate based on the feedback information, the second transmission rate being different from the first transmission,
• wherein the system is configured to transmit at least one of client image information and subsequent client image information corresponding to the image information and the subsequent image information, respectively, to a client, and
• wherein the client is configured to play the at least one of the client image information and the subsequent client image information.

A system installed in an image reception device, the system comprising:

• a reception module for receiving image information from an image transmission device at a first transmission rate;
• an output module for generating client image information corresponding to the received image information and transmitting the client image information to at least one client;
• and
• a control module for generating feedback information and providing the feedback information to the image transmission device,
• wherein the reception module is configured to receive subsequent image information from the image transmission device at a second transmission rate,
• wherein the output module is configured to generate subsequent client image information corresponding to the subsequent image information and transmit the subsequent client image information to the at least one client, and
• wherein the second transmission rate is determined by the image transmission device based on the feedback information.

An image transmission device comprising:

• a streaming module for streaming out image information with a first transmission rate to a system;
• and
• an interface module for receiving feedback information from the system,
• wherein the streaming module is configured to:
• change the first transmission rate to a second transmission rate based on the feedback information;
• and
• stream out subsequent image information to the system,
• wherein the system is configured to transmit at least one of client image information and subsequent client image information corresponding to the image information and the subsequent image information, respectively, to a client, and
• wherein the client is configured to play the at least one of the client image information and the subsequent client image information.
