Abstract

A network interface card is provided for supporting a multi-streaming format and a method thereof. The network interface card including a host interface (102) connected to a communication bus (20) linked with a host CPU (30), a stream interface (101) connected to an AV decoder / encoder (10), and a network interface (103) connected to a network comprises a data transmission module including a tag generating unit (131) for creating a tag for recording time information of AV streams and for adding the tag to the AV streams input through the stream I / F, an aggregator (133) for aggregating a predetermined amount of AV streams, in which tag information is created, in order to form one packet, and a header attaching unit (139) for creating a predetermined header including information about a type of a packet to be transferred and a transmission direction of the packet and for adding the predetermined header to the packet.

Description

technical field [0001] Apparatus and methods consistent with the present invention relate to network interface cards, and more particularly to network interface cards for supporting multi-stream formats. Background technique [0002] With the widespread spread and development of digital technology, users can use various digital devices. For example, various digital audio or video devices (hereinafter referred to as "AV devices") such as DVD players, cable set-top boxes, digital video recorders (DVCRs), digital televisions (DTVs), and personal computers (PCs) can be connected to a network. These AV devices can transmit and / or receive AV streams such as MPEG2 transport streams through various network interfaces (network I / F) and protocols as inter-device communication languages. [0003] Recently, some consumer electronics companies have formed the Digital Home Working Group (DHWG) in order to ensure flexibility among AV devices and activate the home network market. The goal...
