Abstract

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.

First claim

What is claimed is:

1. A client media receiver utilized in conjunction with a display device and a streaming media server, the client media receiver comprising:
a storage medium containing computer-readable code; and
a processor coupled to the storage medium and, when executing the computer-readable code, causing the client media receiver to:
receive a prioritized streaming channel bundle transmitted over a communications network by the streaming media server;
output, to the display device, a first streaming channel contained in the prioritized streaming channel bundle;
further receive a user channel change request to view a second streaming channel contained in the prioritized streaming channel bundle;
monitor for an additional channel change request within a predetermined wait period commencing upon receipt of the user channel change request;
if an additional user channel change request is not received within the predetermined wait period, transmit 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 prioritized streaming channel bundle; and
if an additional user channel change request is received within the predetermined wait period, output a historical gap fill segment from the streaming media server for the second streaming channel received upon conclusion of a recorded segment to the display device wherein the historical gap fill segment extends from a time of live streaming to a conclusion of the recorded segment.

2. The client media receiver of claim 1 wherein, prior to elapse of the predetermined wait period:
the first streaming channel is assigned a higher priority ranking than is the second streaming channel; and
the first streaming channel is received by the client media receiver at an optimal quality level, while the second streaming channel is concurrently received by the client media receiver at a reduced quality level.

3. The client media receiver of claim 1 wherein, prior to elapse of the predetermined wait period:
the first streaming channel is assigned a higher priority ranking than is the second streaming channel; and
the first streaming channel is received by the client media receiver as a continuous stream, while the second streaming channel is concurrently received by the client media receiver as a discontinuous stream.

4. The client media receiver of claim 1 wherein the processor, when executing the computer-readable code, further causes the client media receiver to:
assign a current priority ranking to each streaming channel contained in the prioritized streaming channel bundle; and
when transmitting the channel reprioritization command to the streaming media server, include information in the channel reprioritization command identifying the current priority ranking assigned to each streaming channel contained in the prioritized streaming channel bundle.

5. The client media receiver of claim 4 wherein the processor, when executing the computer-readable code, further causes the client media receiver to:
assign an intermediate priority ranking to at least one streaming channel contained in the prioritized streaming channel bundle based, at least in part, upon a predicted likelihood of receiving a future user channel change request to view the at least one streaming channel.

6. The client media receiver of claim 4 wherein the processor, when executing the computer-readable code, further causes the client media receiver to:
assign at least one streaming channel contained within the prioritized streaming channel bundle a high priority ranking, while assigning a plurality of other streaming channels contained in the prioritized streaming channel bundle lower priority rankings.

7. The client media receiver of claim 1 wherein the prioritized streaming channel bundle comprises over-the-top streaming television programming.

8. The client media receiver of claim 1 wherein the streaming media server comprises a set-top box located in a residence of an end user; and
wherein the processor, when executing the computer-readable code, further causes the client media receiver to:
transmit commands from the client media receiver to the set-top box enabling placeshifting of the prioritized streaming channel bundle for viewing at the client media receiver.

9. The client media receiver of claim 1 wherein the processor, when executing the computer-readable code, further causes the client media receiver to:
in response to receiving the user channel change request to view the second streaming channel, output to the display device:
a live stream of the second streaming channel if currently provided to the client media receiver as part of the prioritized streaming channel bundle transmitted over the communications network; and
a recorded segment of the second streaming channel if a live stream of the second streaming channel is not currently provided to the client media receiver.

10. The client media receiver of claim 9 wherein content from the second streaming channel is presented at a time position; and
wherein the processor, when executing the computer-readable code, further causes the client media receiver to:
when the time position of the second streaming channel is delayed relative to a time of live streaming due to presentation of the recorded segment, provide a user option to advance to the time of live streaming.

11. The client media receiver of claim 1 wherein the processor, when executing the computer-readable code, further causes the client media receiver to:
when receiving a user channel change request to view a second streaming channel contained in the prioritized streaming channel bundle, output to the display device:
the live stream of the second streaming channel if currently provided to the client media receiver as part of the prioritized streaming channel bundle; and
the recorded segment of the second streaming channel if the live stream of the second streaming channel is not currently provided to the client media receiver.

12. The client media receiver of claim 1 wherein the processor, when executing the computer-readable code, further causes the client media receiver to:
if an additional user channel change request is received within the predetermined wait period, repeat the process of monitoring for an additional channel change request within the predetermined wait period.

13. A method carried-out by a streaming media server, the method comprising:
transmitting, from the streaming media server, a prioritized streaming channel bundle over a communications network to a client media receiver, the prioritized streaming channel bundle including a first streaming channel prioritized over a second streaming channel;
receiving, at the streaming media server, a channel reprioritization command from the client media receiver to prioritize the second streaming channel over the first streaming channel in continued transmission of the prioritized streaming channel bundle; and
in response to receipt of the channel reprioritization command at the streaming media server, further transmitting the prioritized streaming channel bundle over the communications network to the client media receiver, while prioritizing second streaming channel over the first streaming channel;
wherein, when the first streaming channel is prioritized over the second streaming channel, the streaming media server transmits the first streaming channel at an optimal quality level, while concurrently transmitting the second streaming channel at a reduced quality level;
wherein, when the second streaming chan
