Wherein, it is described from play the first decoded signal switch to play the second decoded signal include：
The state of first video window is changed to hidden state from dispaly state；By the state of the second video window from hidden
Tibetan state is changed to dispaly state.
In the embodiment of the present invention, after the broadcasting of the second decoded signal is ready, before the first decoder stops to switching
The programme signal of current channel is decoded；Or, first decoder continue to the progress of the programme signal of the current channel before switching
Decoding.
For the first situation, after the handoff is complete, the first decoder is stopped, and only the second decoder is in solution
Code state, that is to say, that in normal viewing, only in running order there are one decoder, another is in idle condition, only
Have after handover request is received, and before switching completion, two decoders are simultaneously in decoded state.
For the second situation, after the handoff is complete, the first decoder keeps the program letter of the current channel before exchange
It number is decoded, that is to say, that two decoders are in running order simultaneously, this in the case of playback button is frequently clicked
Than advantageous, furthermore, it is possible to a timer be set, if the corresponding channel of the first decoder is not cut in the given time
Current channel is changed to, then the first decoder stops decoding, for example, can will be set as the predetermined time 3~10 minutes.It is answered certain
With under scene, user usually in the advertising time or is temporarily switched to other channel viewing, is watched before being switched back into after advertisement
Channel, the setting of the predetermined time can preferably be applied under the scene, that is, consider the application scenarios frequently played back, again
Reduce the consumption to system resource and network bandwidth.
In the embodiment of the present invention, after receiving after handover request, before broadcasting second decoded signal is switched to,
Displaying is prepared for the prompt message of switching.For a user, feedback is not received after sending the request, may to use
Family generates doubt, takes for handover request and does not send success, bad usage experience is brought to user, in order to optimize user's body
It tests, can show the prompt message for being prepared for switching, prompt message can include channel information, such as channel number, channel
Actual program title and prompting user command have received at least one in the information handled.Displaying is prepared for cutting
The prompt message changed can by showing that the information that corresponding text information or character pattern combine is shown on the screen,
It can be shown, can also be shown by playing special prompting ringing tone by way of speech play.
Based on design same as the previously described embodiments or similar, the embodiment of the present invention also provides a kind of video play device,
