Abstract

The invention describes a method of efficient way of video delivery in the legacy (non-802.11e) infrastructure networks and a device (Transmitter) based on this method. The invention permits the video stream to bypass the access point and therefore increases the available bandwidth by a factor of two or more and permits increasing the throughput by improving only the radio and antenna on the Transmitter (as opposed to improvements on both the Transmitter and AP necessary without the invention).

Claims

1. A method of efficient transmission of video stream via home 802.11 network bypassing the legacy Access point by using the multicast frames that are sent directly from the video transmission STA to the video reception STA and a device (the Transmitter) utilizing this method.

2. Method and device per claim 1, where the said frames are either not encrypted (if the home network uses no encryption), are encrypted using a WEP key with an index different from the default one (if the home network uses WEP encryption), or a group key with an unused index (if the home network uses WPA-PSK encryption).

3. A method of efficient transmission of video stream via home 802.11 network bypassing the legacy Access point by using the unicast frames that are sent directly from the video transmission STA to the video reception STA, similar to the DLP protocol, but not utilizing the AP for the configuration, and a device (the Transmitter) utilizing this method.
