Methods and apparatuses for dynamic adaptive streaming over HTTP

An apparatus for receiving media data, the apparatus comprising:

• processing circuitry configured to:
• receive a media presentation description (MPD) file that includes an essential property descriptor for session-based dynamic adaptive streaming over hypertext transfer protocol (DASH) operation, the essential property descriptor indicating an address of a session-based description (SBD) file, the SBD file including one or more key-value pairs dynamically generated by a local SBD session controller, each key of the one or more key-value pairs indicating service information of a different service of a local device;
• obtain the SBD file based on the address of the SBD file indicated by the essential property descriptor;
• modify a uniform resource locator (URL) based on the obtained SBD file;
• and
• acquire a resource from a remote server based on the modified URL.

A non-transitory computer-readable storage medium storing instructions which, when executed by a computer for receiving media data, cause the computer to perform:

• receiving a media presentation description (MPD) file that includes an essential property descriptor for session-based dynamic adaptive streaming over hypertext transfer protocol (DASH) operation, the essential property descriptor indicating an address of a session-based description (SBD) file, the SBD file including one or more key-value pairs dynamically generated by a local SBD session controller, each key of the one or more key-value pairs indicating service information of a different service of a local device;
• obtaining the SBD file based on the address of the SBD file indicated by the essential property descriptor;
• modifying a uniform resource locator (URL) based on the obtained SBD file;
• and
• acquiring a resource from a remote server based on the modified URL.
