Media presentation description

Abstract

A method for indicating repeat occurrences of advertisements in media content may include one or more of the following. The method may include inserting a first descriptor element for a media content in a media presentation description (MPD) associated with the media content. The method may include inserting a second descriptor element for a repeat occurrence of the media content in the MPD. The second descriptor element may indicate that, during the repeat occurrence of the media content, the media content be presented from the beginning.

1 - 15 . (canceled) 
     
     
         16 . A method comprising:
 providing a plurality of period elements in a media presentation description (MPD) for a MPEG-DASH media asset; and   inserting a descriptor element in a period element of the plurality of period elements to indicate a last period element corresponding with the MPEG-DASH media asset.   
     
     
         17 . The method of  claim 16 , wherein inserting the descriptor element comprises inserting a string that indicates the last period element corresponding with the MPEG-DASH media asset. 
     
     
         18 . The method of  claim 16 , wherein the period element is the last period element corresponding with the MPEG-DASH media asset. 
     
     
         19 . The method of  claim 16 , wherein providing the plurality of period elements comprises generating the plurality of period elements or receiving the plurality of period elements. 
     
     
         20 . (canceled) 
     
     
         21 . The method of  claim 16 , further comprising inserting a second descriptor element in a second period element of the plurality of period elements, wherein the second descriptor element indicates that the second period element is not the last period element associated with the MPEG-DASH media asset. 
     
     
         22 - 23 . (canceled) 
     
     
         24 . The method of  claim 16 , wherein the descriptor element comprises a SupplementalProperty descriptor element. 
     
     
         25 . (canceled) 
     
     
         26 . The method of  claim 16 , further comprising sending the plurality of period elements to a media playback client over a communication network. 
     
     
         27 . A method comprising:
 receiving a period element corresponding with a MPEG-DASH media asset;   determining whether the period element is the last period element associated with the media asset; and   managing a playback resource associated with the media asset based on determining whether the period element is the last period element associated with the media asset.   
     
     
         28 . The method of  claim 27 , wherein determining whether the period element is the last period element comprises determining whether the period element includes a descriptor element that indicates that the period element is the last period element of the media asset, the descriptor element comprising a SupplementalProperty descriptor element. 
     
     
         29 . The method of  claim 27 , wherein managing the playback resource comprises purging a playback buffer based on determining that the period element is the last period element associated with the media asset. 
     
     
         30 . The method of  claim 27 , wherein managing the playback resource comprises maintaining a current state of a playback buffer based on determining that the period element is not the last period element. 
     
     
         31 - 39 . (canceled) 
     
     
         40 . A computing device comprising:
 a processor configured to:
 provide a plurality of period elements in a media presentation description (MPD) for a MPEG-DASH media asset; and 
 insert a descriptor element in a period element of the plurality of period elements to indicate a last period element corresponding with the MPEG-DASH media asset. 
   
     
     
         41 . The computing device of  claim 40 , wherein the processor is configured to insert the descriptor element by inserting a string that indicates the last period element corresponding with the MPEG-DASH media asset. 
     
     
         42 . The computing device of  claim 40 , wherein the period element is the last period element corresponding with the MPEG-DASH media asset. 
     
     
         43 . The computing device of  claim 40 , wherein the processor is configured to provide the plurality of period elements by generating the plurality of period elements or by receiving the plurality of period elements. 
     
     
         44 . The computing device of  claim 40 , wherein the descriptor element comprises a SupplementalProperty descriptor element. 
     
     
         45 . A computing device comprising:
 a communication interface;   a processor coupled with the communication interface, wherein the processor is configured to:
 receive a period element corresponding with a MPEG-DASH media asset; 
 determine whether the period element is the last period element associated with the media asset; and 
 manage a playback resource associated with the media asset based on determining whether the period element is the last period element associated with the media asset. 
   
     
     
         46 . The computing device of  claim 45 , wherein the processor is configured to determine whether the period element is the last period element by determining whether the period element includes a descriptor element that indicates that the period element is the last period element of the media asset, the descriptor element comprising a SupplementalProperty descriptor element. 
     
     
         47 . The computing device of  claim 45 , wherein the processor is configured to manage the playback resource by purging a playback buffer based on determining that the period element is the last period element associated with the media asset. 
     
     
         48 . The computing device of  claim 45 , wherein the processor is configured to manage the playback resource by maintaining a current state of a playback buffer based on determining that the period element is not the last period element.
