Claim 5:
6. A method comprising:
receiving 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;
receiving, 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 a 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 representations are equal or substantially equal;
receiving at least one decoder reset picture of the second representation; and
decoding 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.
