Aspects of the disclosure provide methods, apparatuses, and non-transitory computer-readable mediums for receiving media data of a session. One apparatus includes processing circuitry that receives a media presentation description (MPD) file and one or more session-based description (SBD) files. The MPD file includes one or more essential property descriptors for session-based dynamic adaptive streaming over hypertext transfer protocol (DASH). Each of the one or more essential property descriptors for session-based DASH is associated with a different SBD file in the one or more SBD files. The processing circuitry determines, for a period in the MPD file, whether the period has a supplemental property descriptor for session-based DASH. The processing circuitry applies all of the one or more SBD files to the period in response to the period not having any supplemental property descriptor for session-based DASH.
