Embodiment approach 900

[0049] Figure 9 An exemplary embodiment 900 is shown in which MPD extensions may be generated. The source MPD 910 and the updated MPD 920 can be included in the MPD extension. The source MPD 910 can be the MPD received from the streaming media server. For the sake of clear description, its content will not be repeated here. The updated MPD 920 It may be one of the MPDs mentioned in the above embodiments (eg, the embodiment 300 shown in the updated MPD 920 ). The UE may parse the MPD extension and choose to use one of the source MPD 910 and the update MPD 920 .

[0050] Figure 10A and Figure 10B An exemplary embodiment 1000 is shown in which the MPD and segment data may be packaged into mutually independent portions of a file, such as a Multipurpose Internet Mail Extensions (MIME) Hypertext Markup Language (HTML) (MHTML) file. The file may be a multipart message in MIME format. In one embodiment, MPD is associated with segment data through URL and / or URI, for example, s...
