Abstract:
1. A terminal apparatus comprising: a communication unit that simultaneously establishes two or more communication paths between said communication unit and a content delivery server connected to said communication unit, wherein said communication unit is implemented in hardware; a session managing unit that manages said two or more communication paths, wherein said session managing unit is implemented in said hardware; a decoder that decodes content data received from said two or more communication paths, wherein said decoder is implemented in said hardware, wherein when said communication unit receives first content data via a first communication path of said two or more communication paths, said session managing unit selects a second communication path from among said two or more communication paths, and transmits a request for a delivery of second content data via said second communication path to said content delivery server, and wherein after said communication unit receives the first content data from said first communication path and the second content data from said second communication path simultaneously, said session managing unit terminates reception of the first content data via said first communication path, and performs switching between said first communication path and said second communication path; a first buffer which stores the first content data from said first communication path; and a second buffer which stores the second content data from said second communication path, wherein when said communication unit receives the first content data from said first communication path and the second content data from said second communication path simultaneously, said session managing unit determines a content time of the second content data in said second buffer, which is not less than the minimum content time in the first content data in said first buffer, as a session switching time which is a time to switch the first buffer and the second buffer, and wherein said session managing unit switches the content data received from said two or more communication paths, from the first content data stored in said first buffer to the second content data stored in said second buffer at the session switching time.
