Patent ID: 7958530

Claim:
A network information communication system, comprising (a) a display apparatus and (b) an information terminal apparatus which are connected through a network, the system communicating a video image data therebetween, wherein the information terminal apparatus includes: (1) a communicating unit which receives the video image data from the display apparatus through the network by TCP/IP communication; (2) a decode unit which decodes the video image data received by the communicating unit, which outputs the decoded video image data to a display unit of the information terminal apparatus, and which detects an occurrence of a decode error having occurred in the decode unit during receiving of the video image data, wherein the communicating unit notifies the occurrence of the decode error to the display apparatus through the network by turning on a decode flag of a TCP/IP header, wherein the display apparatus, which is connected with a video player, includes: (1) a communicating unit which transmits the video image data being played in the video player to the information terminal apparatus by TCP/IP communication; (2) a storage unit which stores a time stamp of a play position at which the decode error occurs by specifying the time stamp corresponding to a sequence number of the TCP/IP header of which the decode flag is turned on, and which stores a still image corresponding to the time stamp, in response to the notification of the decode error from the information terminal apparatus during the video image data communication; (3) a display control unit which controls to display the still image stored in the storage unit on a display unit of the display apparatus; and (4) an operation unit which selects the still image displayed on the display unit in accordance with a user's instruction, and wherein the video image data is played from the play position of the time stamp corresponding to the still image selected by the operation unit.
