Claim 13:
14. A video encoder system comprising:
a buffer, implemented in memory, configured to store multiple pictures in a video sequence to be encoded; and
a video encoder, implemented with one or more processing units and memory, configured to perform operations to encode the multiple pictures, thereby generating encoded data in a bitstream for the multiple pictures, wherein each of the multiple pictures is designated in the encoded data as being 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, and wherein the operations include:
encoding a first picture among the multiple pictures, the first picture being designated as the first picture type; and
encoding a second picture among the multiple pictures, the second picture being designated as the third picture type.
