Devices, systems, method, and program products are provided, which support temporally-seamless change functionalities during multichannel streaming sessions established between a streaming media server and a client media receiver. In embodiments, the method includes outputting, to a display device, a first streaming channel contained in a streaming channel bundle and assigned a high priority level. When receiving a channel change request to view a second streaming channel, the client media receiver monitors for additional channel change requests over a predetermined wait period. If an additional channel change request is received within the wait period, the client media receiver repeats the step of monitoring. Conversely, if an additional channel change request is not received with the wait period, the client media receiver sends a channel reprioritization command to the streaming media server to prioritize the second streaming channel over the first streaming channel in continued transmission of the streaming channel bundle.
