An apparatus herein coordinates streaming of multimedia content from a streaming server to a client device. While the client device is receiving a first multicast stream from the streaming server, the apparatus receives notification of the recent or impending occurrence of a defined event of interest characteristic of the multimedia content in a second multicast stream. Responsive to receiving such notification, the apparatus directs the streaming server to stream to the client device a third stream whose video content comprises windowed video content of both the first and second multicast streams. This windowed video content comprises video content from the first and second multicast streams arranged in respective windows. Such event-triggered streaming thus enables a user of the client device to simultaneously watch both the first and second streams, as desired, by efficiently receiving only a single third stream.
