Abstract
An encoding method includes encoding moving image; determining whether an information amount of the encoded moving image data in units of a picture satisfies a threshold to control a virtual buffer obtained by virtually modeling a reception buffer of a decoding device that is a transmission destination of the encoded moving image data; and setting, by dividing a picture included in the encoded moving image data, a decoding time for each divided picture to cause the decoding device to decode each divided picture when the determining determines the information amount of the encoded moving image does not satisfy the threshold to control the virtual buffer.
Claims6
An encoding method comprising:
- encoding moving image data;
- determining whether an information amount of the encoded moving image data in units of a picture satisfies a threshold to control a virtual buffer obtained by virtually modeling a reception buffer of a decoding device that is a transmission destination of the encoded moving image data;
- and
- setting, by dividing a picture included in the encoded moving image data, a decoding time for each divided picture to cause the decoding device to decode each divided picture when the determining determines the information amount of the encoded moving image data does not satisfy the threshold to control the virtual buffer, wherein
- the decoding device divides the encoded moving image data, the decoding time of which is earlier than a display time, and assigns a different decoding time to each of the divided encoded moving image data.
An encoding device comprising:
- a processor;
- and
- a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to,
- encode moving image data;
- determine whether an information amount of the encoded moving image data in units of a picture satisfies a threshold to control a virtual buffer obtained by virtually modeling a reception buffer of a decoding device that is a transmission destination of the encoded moving image data;
- and
- divide a picture included in the encoded moving image data and to set a decoding time for each divided picture to cause the decoding device to decode each divided picture when the determination determines the information amount of the encoded moving image data does not satisfy the threshold to control the virtual buffer, wherein
- the decoding device divides the encoded moving image data, the decoding time of which is earlier than a display time, and assigns a different decoding time to each of the divided encoded moving image data.
