RUI system, RUI server, RUI terminal apparatus and controlling method thereof

A controlling method of a first remote user interface (RUI) terminal in an RUI service environment, the controlling method comprising:

• receiving, from an RUI server, a request to trans-code stream data, in response to the RUI server determining that the RUI server does not have enough trans-coding resources to trans-code the stream data;
• transmitting, to the RUI server, an answer message regarding available trans-coding resources of the first RUI terminal;
• receiving, from the RUI server, trans-coding process information including the stream data;
• trans-coding the stream data into a format of a second RUI terminal which requests a streaming service, based on the trans-coding process information, to yield trans-coded stream data;
• and
• transmitting the trans-coded stream data to the second RUI terminal.

A remote user interface (RUI) server comprising:

• a communication interface configured to communicate with a plurality of RUI terminals regarding a streaming service;
• and
• a processor configured to:
• receive, from an external server, stream data related to streaming service request information received from a first RUI terminal among the plurality of RUI terminals,
• determine whether the RUI server has enough trans-coding resources to trans-code the received stream data, to yield a determination,
• in response to the determination indicating that the RUI server has the enough trans-coding resources, trans-code the received stream data, and
• in response to the determination indicating that the RUI server does not have the enough trans-coding resources, transmit a request to trans-code the received stream data to a second RUI terminal among the plurality of RUI terminals, the second RUI terminal being different from the first RUI terminal.

A remote user interface (RUI) terminal apparatus, comprising:

• a communication interface configured to communicate with an RUI server;
• and
• a processor configured to:
• receive, from the RUI server, a request to trans-code stream data, in response to the RUI server determining that the RUI server does not have enough trans-coding resources to trans-code the stream data,
• transmit, to the RUI server, an answer message regarding available trans-coding resources of the RUI terminal,
• receive, from the RUI server, trans-coding process information including the stream data,
• trans-code the stream data into a format of another RUI terminal requesting a streaming service, based on the trans-coding process information, to yield trans-coded stream data, and
• transmit the trans-coded stream data to the another RUI terminal.

A remote user interface (RUI) system configured to provide an RUI service, the RUI system comprising:

• an RUI server configured to trans-code stream data received from an external server, and transmit the trans-coded stream data to a first RUI terminal which requests a streaming service, the first RUI terminal being one among a plurality of RUI terminals;
• and
• the first RUI terminal apparatus configured to perform signal processing on the stream data trans-coded by the RUI server and output a result of the signal processing,
• wherein the RUI server is further configured to, in response to the RUI receiving streaming service request information from the first RUI terminal and upon determining that the RUI terminal does not have enough trans-coding resources to trans-code the stream data, transmit, to a second RUI terminal among the plurality of RUI terminals, a request to trans-code the received stream data, the second RUI terminal being capable of providing available trans-coding resources.
