1Area of stationary object
If content viewing is transferred from portable terminal to information processing apparatus, then viewing can be continued on larger screen, but multiple operation steps are required increasing user interaction
Solution Approach 1:
The portable terminal acquires identification information about the content being viewed and transmits it to the information processing apparatus before the user completes the transfer operation. This preliminary acquisition and transmission of content identification data enables the receiving device to automatically prepare and display the content, reducing the number of steps the user must manually perform.
Solution Approach 2:
The system automatically handles the content transfer process by having the portable terminal transmit its own identification information and the information processing apparatus automatically acquire and display the corresponding content. This self-service mechanism eliminates the need for extensive manual intervention from the user, allowing seamless content continuation.
2Area of stationary object
If content viewing is transferred from portable terminal to information processing apparatus, then viewing can be continued on larger screen, but transfer process becomes more complex
Solution Approach 1:
The patent extracts only the essential identification information from the portable terminal's content state and transmits it to the information processing apparatus. By taking out only the necessary identification data rather than transferring the entire content stream, the system simplifies the transfer process while maintaining the ability to continue viewing.
Solution Approach 2:
The identification information acts as an intermediary that bridges the portable terminal and information processing apparatus. Instead of directly transferring complex content data, the system uses this intermediate identification information to trigger automatic content acquisition and display, simplifying the overall transfer mechanism.

AI summary
A portable terminal includes a receiving unit which receives content information, an external device communication unit which conducts communication with an external information device, a display unit which displays the content information received by the receiving unit, an acquiring unit which acquires identification information identifying the content information displayed by the display unit, an operation unit which receives an operation indication from a user, and a control unit which conducts control such that if a transmission indication of the identification information is received by the operation unit while the content information is being displayed, the identification information acquired by the acquiring unit is transmitted to the external information device and the display of the content information by the display unit is terminated.
