1. A video server comprising:
- a memory;
a processor coupled to the memory configured to;
select a unicast mode in response to a request for video content from a single mobile video device via a network and that receives location data from a plurality of mobile video devices via the network;
select a multicast mode in response to multiple requests for the video content from the plurality of mobile video devices and an analysis of the location data that indicates that the plurality of mobile video devices are within a common proximity; and
generate a video signal for transmission to the single mobile video device via the network when the unicast mode is selected and for transmission to the plurality of mobile video devices via the network when the multicast mode is selected.

Abstract
A video transmission system includes a video server module that selectively operates in a unicast mode and a multicast mode, wherein the video server module generates a video signal that includes a unicast video signal when the video server module is in the unicast mode and that includes a multicast video signal when the video server module is in the multicast mode. A wireless access device transmits the video signal to at least one mobile video device.

9. A method comprising:
-
selecting, via a video server, a unicast mode in response to a request for video content from a single mobile video device; receiving, via a video server, multiple requests for the video content and location data from a plurality of mobile video devices; analyzing, via a video server, in response to the multiple requests, the location data to determine when the plurality of mobile video devices are within a common proximity; selecting, via a video server, a multicast mode when the plurality of mobile video devices are within the common proximity; and generating, via a video server, a video signal for transmission that includes a unicast video signal when the unicast mode is selected and that includes a multicast video signal when the multicast mode is selected. - View Dependent Claims (10, 11, 12, 13, 14)

15. A video transmission system comprising:
-
a video server module that selectively operates in a unicast mode in response to a request for video content from a single mobile video device via a network and that receives location data from a plurality of mobile video devices via the network and that selectively operates in a multicast mode in response to multiple requests for the video content from the plurality of mobile video devices and an analysis of the location data that indicates that the plurality of mobile video devices are within a common proximity; wherein the video server module generates a video signal that includes a unicast video signal when the video server module is in the unicast mode and that includes a multicast video signal when the video server module is in the multicast mode; and wherein the video server module sends the video signal to the single mobile video device via the network in the unicast mode and to the plurality of mobile video devices via the network in the multicast mode. - View Dependent Claims (16, 17, 18, 19, 20)
