Embodiment Construction

[0043] For the transmission device of the embodiment of the present invention, refer to Figure 6 Be explained.

[0044] A central processing unit (CPU) 400 will exercise overall control of the conveyor.

[0045] The MPEG standard decoder 402 receives video and audio (AV) data, and decodes the received AV data according to the MPEG standard to generate an MPEG standard transport stream, and provides the MPEG standard transport stream to the priority transmission control unit 404 .

[0046] Priority transmission control unit 404 obtains the MPEG standard transport stream, text data, WWW browser data and other diversified data packets output by MPEG standard decoder 402, and provides them to media access control processor 406. The control signal of the type of data is provided to the media access control processor 406 .

[0047] The detailed description is as follows: the priority transmission control section 404 checks whether the corresponding data packet is an MPEG standard...

Abstract

The method thereof comprises: checking the specific bits in a specific position of data packet to be transmitted in order to decide if it is described as an audio / video data; if the bits indicates it is audio / video data, then the data packet is wireless transmitted in priority. The apparatus thereof consists of: a controller for checking the bits in a specific position of data packet to decide if it is described as audio / video data and in term of the checking result controlling a priority transmission of the data packet; and a WLAN transmitting device for transmitting in priority the data packet from the controller.

Description

technical field [0001] The present invention relates to a method and device for transmitting data through a wireless local area network, in particular to a method and device for transmitting audio and video (AV: Audio and Video) data through a wireless local area network. Background technique [0002] In recent years, with the increase in consumer demand for wireless network technology, data transmission technology using wireless LAN is also developing rapidly. In particular, the technical standard of the wireless network is improved from the wireless local area network standard IEEE802.11b to the IEEE802.11a standard, and the data transmission rate is also increased from 11Mbps to 54Mbps. Therefore, with the improvement of this data transmission rate, it has become a reality to receive and send video and audio (AV) data through a wireless local area network. [0003] Generally, in order to transmit audio-visual (AV) data through a wireless LAN, not only broadcasting requir...
