1. A method comprising:
encoding video media content into at least a first representation and a second representation, wherein:
the first representation comprises 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; and
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,
wherein the first representation and the second representation are encoded to enable decoding of a 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 decoder reset picture, without the corresponding switchable inter-coded picture having been decoded.
