Abstract
To enable image data of the interlacing scheme to undergo encoding of an open GOP. An image encoding unit encodes image data of each picture constituting image data in an interlacing scheme in an NAL unit structure and generates a video stream having the encoded image data of each picture. The image encoding unit sets an NAL unit type of a slice of encoded image data of a picture forming a field pair with an intra picture constituting a random access point to a unique type which indicates a picture that is dependent on the intra picture and forms the field pair with the intra picture.

An encoding device comprising:
- an image encoding unit configured to encode image data of each picture constituting image data in an interlacing scheme in an NAL unit structure and generate a video stream having the encoded image data of each picture,
- wherein the image encoding unit sets an NAL unit type of a slice of encoded image data of a picture forming a field pair with an intra picture constituting a random access point to a unique type which indicates a picture that is dependent on the intra picture and forms the field pair with the intra picture.
An encoding method comprising:
- an image encoding step by an image encoding unit of encoding image data of each picture constituting image data in an interlacing scheme in an NAL unit structure and generating a video stream having the encoded image data of each picture,
- wherein, in the image encoding step, an NAL unit type of a slice of encoded image data of a picture forming a field pair with an intra picture constituting a random access point is set to a unique type which indicates a picture that is dependent on the intra picture and forms the field pair with the intra picture.
A transmission device comprising:
- an image encoding unit configured to encode image data of each picture constituting image data in an interlacing scheme in an NAL unit structure and generate a video stream having the encoded image data of each picture;
- and
- a transmission unit configured to transmit a container in a predetermined format which includes the generated video stream,
- wherein the image encoding unit sets an NAL unit type of a slice of encoded image data of a picture forming a field pair with an intra picture constituting a random access point to a unique type which indicates a picture that is dependent on the intra picture and forms the field pair with the intra picture.
A decoding device comprising:
- an image decoding unit configured to decode a video stream having encoded image data of each picture obtained by encoding image data of each picture constituting image data in an interlacing scheme in an NAL unit structure to obtain the image data in the interlacing scheme,
- wherein, in the video stream, an NAL unit type of a slice of encoded image data of a picture forming a field pair with an intra picture constituting a random access point is set to a unique type which indicates a picture that is dependent on the intra picture and forms the field pair with the intra picture.
A decoding method comprising:
- an image decoding step by an image decoding unit of decoding a video stream having encoded image data of each picture obtained by encoding image data of each picture constituting image data in an interlacing scheme in an NAL unit structure to obtain the image data in the interlacing scheme,
- wherein, in the video stream, an NAL unit type of a slice of encoded image data of a picture forming a field pair with an intra picture constituting a random access point is set to a unique type which indicates a picture that is dependent on the intra picture and forms the field pair with the intra picture.
A reception device comprising:
- a reception unit configured to receive a container in a predetermined format which includes a video stream having encoded image data of each picture obtained by encoding image data of each picture constituting image data in an interlacing scheme in an NAL unit structure;
- and
- an image decoding unit configured to obtain the image data in the interlacing scheme by decoding the video stream included in the received container,
- wherein, in the video stream, an NAL unit type of a slice of encoded image data of a picture forming a field pair with an intra picture constituting a random access point is set to a unique type which indicates a picture that is dependent on the intra picture and forms the field pair with the intra picture.
