Meanwhile, in data transmission using a transmission control protocol (TCP), TCP is a connection-oriented protocol based on IP (Internet Protocol). This means that the client-server has to undergo a connection establishment process. In the TCP / IP suite, data is segmented and transmitted, and check checksum, sequence number (S / N) check, and data corruption are confirmed. TCP is a reliable transport mechanism that requires not only receipt acknowledgment but also completeness and serial number to the recipient.

TCP uses port numbers for inter-process communication and supports flow control and error control that can be provided by the transport layer protocol. Sliding window protocol is used for flow control and TCP timer, retransmission etc. are used for error control in addition to checksum.

TCP flow control refers to controlling and defining the amount of data transmission on the transmitting side at the receiving end. TCP uses a buffer to store data that is passed in an application program, and defines a window to determine the size of the data to be transmitted. TCP can transmit only the number of bytes defined in the window. For this flow control, a sliding window technique is used.

In general, the TCP transmission rate is inversely proportional to the end-to-end latency and is proportional to the "Rcv Window ". However, due to problems such as loss and memory, it is usually difficult to increase the "Rcv Window" of the kernel by 800 KB or more. As a result, it is limited to process high definition video such as UD (Ultra definition) video. Accordingly, the present invention recognizes the UD-class video or higher and processes the video using a plurality of TCP connections at the same time.

[0156] For example, the mobile terminal 100 sets the video display device 200 as a proxy, and requests the video display device 200 to display a Youtube video (content) linked to the selected icon.

The control unit 270 of the video display device 200 requests the server 400 for the requested content (S12).

The control unit 270 determines whether the requested content size is equal to or greater than a preset capacity (for example, a high quality movie file) (S13). The preset capacity may be changed according to the intention of the user or the designer.

If the capacity of the content requested by the mobile terminal 100 is less than the predetermined capacity, the controller 270 requests the server 400 to transmit the requested content through a single TCP connection (S14 ).

The control unit 270 may reject the content request if the requested content is not video content.

On the other hand, when the capacity of the content requested by the mobile terminal 100 is equal to or greater than a preset capacity, the controller 270 generates a plurality of TCP connections (S15). The number of TCP connections may be changed according to the capacity of the contents or may be changed according to the intention of the user or the designer.
