Abstract

According to an aspect of an invention, a method for signaling reference pictures in video coding is disclosed. The method comprises: decoding a number of entries in a reference picture list syntax structure; decoding a number of reference index active minus one syntax in a slice header, if the number of entries is greater than one; and deriving an active variable by using the number of reference index active minus one syntax.

Claims (9)

1. A method of decoding video data, the method comprising:

decoding a flag in a reference picture list structure, wherein the flag specifies whether long-term reference picture Picture Order Count (POC) least significant bit (LSB) information is signaled; and

decoding the long-term reference picture POC LSB information in the reference picture list structure or in a slice header according to a value of the flag.

2. A device comprising one or more processors configured to:

decode a flag in a reference picture list structure, wherein the flag specifies whether long-term reference picture Picture Order Count (POC) least significant bit (LSB) information is signaled; and

decode the long-term reference picture POC LSB information in the reference picture list structure or in a slice header according to a value of the flag.

3. A method of encoding data, the method comprising:

encoding a flag in a reference picture list structure, wherein the flag specifies whether long-term reference picture Picture Order Count (POC) least significant bit (LSB) information is signaled; and

encoding the long-term reference picture POC LSB information in the reference picture list structure or in a slice header according to a value of the flag.
