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.

Disclosed is an interface display method, including: acquiring a button value and judging whether the acquired button value is a button value associated with any one of the shortcut applications, if yes, sending a first preset message and a second preset message to each of the shortcut applications; when a first shortcut application having an application identifier being different from the application identifier carried by the first preset message receives the first preset message, judging whether an application interface is in a display state, if yes, terminating the display of the application interface; when a second shortcut application having an application identifier being the same as the application identifier carried by the first preset message receives the first preset message and the second preset message, judging whether an application interface is in a display state, if yes, terminating the display of the application interface, or else displaying the application interface.

The application discloses video data redundancy control methods and apparatuses. Video packet redundancy control information is determined according to packet loss at a reception apparatus. The video packet redundancy control information is received from the reception apparatus. Video data is encoded according to the video packet redundancy control information to obtain encoded video data of a plurality of frames by a transmission apparatus. A frame-level redundancy budget is allocated for one of the plurality of frames according to the video packet redundancy control information. Further, the one of the plurality of frames is packetized according to the frame-level redundancy budget to generate a packetized frame. Redundancy coding is performed on the packetized frame to generate video packets including data packets and redundant packets for transmission to the reception apparatus.
