Claim 8:
9. One or more computer-readable memory or storage devices having stored thereon encoded data in a bitstream for multiple pictures in a video sequence, each of the multiple pictures being designated in the encoded data as one of multiple picture types, the multiple picture types including (a) a first picture type indicating a broken link access (“BLA”) picture that is capable of being used as a random access point (“RAP”) picture and does not have any associated non-decodable leading pictures, but may have one or more associated decodable leading pictures, (b) a second picture type indicating a BLA picture that is capable of being used as a RAP picture but does not have any associated leading pictures, and (c) a third picture type indicating a random access decodable leading (“RADL”) picture, the encoded data being organized to facilitate decoding of the multiple pictures, in a computer system that implements a video decoder, by operations that include:
decoding a first picture among the multiple pictures, the first picture being designated as the first picture type; and
decoding a second picture among the multiple pictures, the second picture being designated as the third picture type.
