Video switching for streaming video data |
| 摘要 |
In one example, an apparatus includes a processor configured to provide information to a client device for accessing data for a first representation of a video sequence and a second representation of the video sequence, and to provide information to the client device indicating that the client device can, during transmission of the data for the first representation, switch to the second representation without experiencing a presentation gap when displaying the video sequence and without simultaneously executing more than one decoder to decode the data for the first representation and the second representation during the switch, in response to a first request from the client device to retrieve data from the first representation. In this manner, the client device may use the information to perform seamless switching between the representations. |

1. A method of sending video data, the method comprising:
providing information to a client device for accessing data for a first representation of a video sequence and a second representation of the video sequence; providing information to the client device indicating that the client device can, during transmission of the data for the first representation, switch to the second representation without experiencing a presentation gap when displaying the video sequence and without simultaneously executing more than one decoder to decode the data for the first representation and the second representation during the switch comprising sending, to the client device, a delay value for switching from the first representation to the second representation; in response to a first request from the client device to retrieve data from the first representation, sending the requested data from the first representation to the client device; in response to a second request from the client device to retrieve data from the second representation after sending the requested data from the first representation, sending the requested data from the second representation to the client device. |
