Abstract

Techniques and systems are provided for encoding and decoding video data. For example, a method of decoding video data includes accessing an encoded video bitstream encoded according to a first coding protocol. The encoded video bitstream includes one or more enhancement layers and a video parameter set defining parameters of the encoded video bitstream. The method further includes determining that a syntax element indicative of a number of video signal information syntax structures provided in the encoded video bitstream is not present in the video parameter set. The method further includes determining whether a base layer is included in the encoded video bitstream or to be received from an external source. The method further includes determining the number of video signal information syntax structures included in the video parameter set to be a first value or a second value based on whether the base layer is included in the encoded video bitstream or to be received from the external source.
