One to many transmission method and system to transmit real-time video and audio data on wireless local area network
First Claim
1. A one-to-many transmission method to transmit real-time video and audio data on wireless local area network (WLAN) satisfying a WLAN transmission standard and formed with a first station, a second station, and at least one third station, said first station being capable of providing simultaneous transmission of at least one video and audio program to said second station, said method comprising:
- (a) using said first station to calculate for the number of said at least one video and audio program that said WLAN can accommodate, according to the bandwidth of said WLAN;
(b) transmitting a command-packet from said second station to said first station for performing a command action of said command-packet;
(c) transmitting a set-packet periodically from said first station to said second station;
(d) checking said set-packet for any errors by said second station, in which said step (b) is performed again if there is some error occurred;
(e) transmitting periodically at least one data-packet from said first station to said second station, said at least one data-packet containing at least one video and audio program; and
(f) intercepting said set-packet by said third station and, according to the configuration of said set-packet, receiving said at least one data-packet and selectively playing said at least one video and audio program contained in said at least one data-packet by said third station.

Abstract
A one-to-many transmission method and system to transmit real-time video and audio data on wireless local area network, which includes a first station, a second station, and at least one third station. The first station provides at least one video and audio program and a set-packet, and periodically transmits them to the second station. The second station transmits a command-packet to the first station to determine the content of video and audio program transmitted by the first station, and receives the set-packet to confirm whether the set-packet is correct or not. The third station intercepts and receives the set-packet, and according to the configuration of the set-packet changes its network configuration to receive the video and audio program transmitted by the first station, and selectively play the content.

13. A one-to-many transmission system for transmitting real-time video and audio data on wireless local area network (WLAN), said system comprises:
-
a first station providing at least one video and audio program and a set-packet and using a WLAN to transmit periodically;
a second station transmitting a command-packet to said first station to determine said at least one video and audio program transmitted by said first station, to receive said set-packet and said at least one video and audio program transmitted by said first station, and to confirm if said set-packet is correct or not; and
at least one third station scanning all transmission channels available for said WLAN to intercept said set-packet, and according to said set-packet configuration, to receive at least one data-packet and selectively play one of said at least one data-packet. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
