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.
