Problems solved by technology

However, systems using hardware protocol stacks have the disadvantage that there is a limit to the number of channels used for Internet connections
However, in general computer systems, various Internet application programs use multiple channels at the same time, so when only the hardware protocol stack is used, the number of Internet application programs that can be executed simultaneously is limited to only one or two programs

Embodiment Construction

[0029] The present invention will now be described more fully with reference to the accompanying drawings that illustrate example embodiments of the invention.

[0030] refer to figure 2 , the digital TV 210 or the mobile device 230 can receive and reproduce a large amount of multimedia data through the multimedia server 220 . In each apparatus, multimedia communication devices 211, 221, and 231 using a software protocol stack and a hardware protocol stack according to the present invention are included.

[0031] By using the multimedia communication device according to the present invention, when digital TV 210 or mobile device 230 transmits a large amount of high-speed multimedia data, it can use the hardware protocol stack, and when it transmits a small amount of data other than multimedia data such as the control of multimedia data Data, or common Internet applications, use the software protocol stack.

[0032] Therefore, by using a hardware protocol stack when transfer...

Abstract

A multimedia communication device using a software protocol stack and a hardware protocol stack, a communication method thereof, and a computer program product are provided. The multimedia communication device includes: a hardware protocol stack processing a packet using hardware; and a software protocol stack processing the packet using software. According to the device and method, while the overhead to the CPU can be reduced to enhance the processing speed, a large volume of multimedia data can be transmitted at a higher speed without a limit to the number of channels that can be supported at the same time.

Description

technical field [0001] The present invention relates to a multimedia communication device using Transmission Control Protocol / Internet Protocol (TCP / IP), in particular to a multimedia communication device using a software protocol stack and a hardware protocol stack and a communication method thereof. Background technique [0002] TCP / IP is a standard protocol that provides Internet communications for computers and, like other network protocols, is formed using multiple layers. These layers are called protocol stacks, protocol suites, or protocol structures. [0003] More specifically, the protocol stack is based on the two most important protocols, Transmission Control Protocol / User Datagram Protocol (TCP / UDP) and Internet Protocol (IP). The TCP / UDP protocol is used to transmit data in units of packets, and each packet has a header storing control information. This header includes a port number that distinguishes application protocols such as Hypertext Transfer Protocol (...
