Claim 18:
19. A computer program product comprises at least one non-transitory computer-readable storage medium having computer executable program code instructions stored therein, the computer executable program code instructions comprising program code instructions configured, upon execution, to:
receive at least one bitstream corresponding to a first representation of encoded video media content, the first representation comprising a switchable inter-coded picture, wherein the switchable inter-coded picture comprises a first characteristic that no pictures preceding the switchable inter-coded picture in decoding order are used as reference pictures for non-switchable pictures following the switchable inter-coded picture in decoding order;
receive, from or along the at least one bitstream, an indication about suitability of switching between the first representation and a second representation of the encoded video media content in decoding, wherein the second representation comprises one or more decoder reset pictures aligned with switchable inter-coded pictures of the first representation, wherein the frame rate of the second representation is smaller than or equal to a frame rate of the first representation and resolutions of the first and the second representation are equal or substantially equal;
receive at least one decoder reset picture of the second representation; and
decode the at least one decoder reset picture of the second representation, followed by decoding of pictures of the first representation that are subsequent to a switchable inter-coded picture of the first representation that corresponds to the at least one decoder reset picture, without the corresponding switchable inter-coded picture having been decoded.
