  • Publication number: 20160050388
    Abstract: A remote resource access interface apparatus is provided. A key input unit has keys for generating input key values. A communication unit transmits a connection establishment request message including screen resolution information to, and receives a connection establishment response message including supportable key information from, a portable device. The communication unit transmits input key information to and receives video information from the portable device after establishing the connection. A pixel information processing unit converts the video information to pixel signals for a video output unit to display as a visual image. A key advisor unit extracts supportable key information from the response message and outputs the supportable key information to the video output unit. The video information is video data adjusted in resolution based on the screen resolution information, and the input key value is mapped to one of key values indicated by the key information of the portable device.
