Manifest file updates for network streaming of coded multimedia data

A device for retrieving multimedia data, the device comprising:

• means for retrieving data of a first segment of a representation of multimedia content in accordance with data of a copy of a manifest file stored by the device, wherein the data of the first segment correspond to a period of the multimedia content;
• means for retrieving a portion of a second segment of the representation in accordance with the manifest file, wherein data of the second segment corresponds to the period to which the data of the first segment corresponds, wherein the second segment occurs after the first segment in the representation, and wherein the portion of the second segment indicates that the manifest file is to be updated;
• means for updating the copy of the manifest file stored by the device based on the indication that the manifest file is to be updated;
• and
• means for retrieving media data of the second segment in accordance with the updated manifest file.

A computer program product comprising a non-transitory computer-readable medium having stored thereon instructions that, when executed, cause a processor of a device for retrieving multimedia data to:

• retrieve data of a first segment of a representation of multimedia content in accordance with data of a copy of a manifest file stored by the device, wherein the data of the first segment correspond to a period of the multimedia content;
• retrieve a portion of a second segment of the representation in accordance with the manifest file, wherein data of the second segment corresponds to the period to which the data of the first segment corresponds, wherein the second segment occurs after the first segment in the representation, and wherein the portion of the second segment indicates that the manifest file is to be updated;
• update the copy of the manifest file stored by the device based on the indication that the manifest file is to be updated;
• and
• retrieve media data of the second segment in accordance with the updated manifest file.

A method of sending information for multimedia data, the method comprising:

• sending data of a manifest file of multimedia content to a client device, wherein the manifest file includes information indicative of a first segment of a representation of the multimedia content, wherein data of the first segment corresponds to a period of the multimedia content;
• sending at least a portion of the first segment of the representation to the client device in response to a request from the client device, wherein the portion of the first segment indicates that the manifest file is to be updated, wherein an updated version of the manifest file includes information indicative of a second, different segment of the representation, wherein data of the second segment corresponds to the period to which the data of the first segment corresponds;
• and
• sending, in response to a request received from the client device and formed according to the updated manifest file, data of the second segment to the client device.
