Devices for identifying a leading picture
An electronic device for indicating a leading picture is described. The electronic device includes memory in communication with a processor and instructions stored in the memory. The electronic device encodes a first picture. The electronic device further determines whether a leading picture is present. The electronic device further generates an explicit leading picture indicator if a leading picture is present. The electronic device further sends the explicit leading picture indicator if a leading picture is present.
1. An electronic device for indicating a leading picture, the device comprising:
at least one processor configured to:
identify a first picture including only intra-prediction slices (I-slices) that are decoded using intra prediction only;
generate information of leading pictures included in the first picture,
wherein the information is a Network Access Layer (NAL) unit type associated with a random access picture indicating whether or not the first picture has a subsequent leading picture, and wherein the first picture occurs at a random access point; and
send the information.
2. The electronic device of claim 1 , wherein the leading pictures are one or more pictures following the first picture in a decoding order and preceding the first picture in an output order.
3. The electronic device of claim 1 , wherein the NAL unit type comprises a NAL unit type associated with the Random Access Picture with the subsequent leading picture.
4. The electronic device of claim 1 , wherein the NAL unit type comprises a NAL unit type associated with the Random Access Picture without the subsequent leading picture.
5. A method for indicating a leading picture, the method comprising:
identifying a first picture including only intra-prediction slices (I-slices) that are decoded using intra prediction only;
generating information of leading pictures included in the first picture,
wherein the information is a Network Access Layer (NAL) unit type associated with a random access picture indicating whether or not the first picture has a subsequent leading picture, and wherein the first picture occurs at a random access point; and
sending the information.
6. The method of claim 5 , wherein the leading pictures are one or more pictures following the first picture in a decoding order and preceding the first picture in an output order.
7. The method of claim 5 , wherein the NAL unit type comprises a NAL unit type associated with the Random Access Picture with the subsequent leading picture.
8. The method of claim 5 , wherein the NAL unit type comprises a NAL unit type associated with the Random Access Picture without the subsequent leading picture.
