Abstract

An encoding device includes a processor configured to execute a process. The process includes: first calculating, based on a first system rate for encoding data and transmitting the encoded data to a terminal and a second system rate representing a rate for reproducing the data at the terminal, a decoder storage time during which the encoded data received by the terminal is stored; and adding information of the decoder storage time to the encoded data and transmitting the encoded data added with the information to the terminal.

First claim

What is claimed is:

1. An encoding device comprising:
a processor configured to execute a process including:
calculating, based on a first system rate that is predetermined and at which data that is encoded in the encoding device is transmitted to a terminal and a second system rate that represents a rate for reproducing the data at the terminal and is calculated based on the data and data used to multiplex and synchronize the data, a decoder storage time; and
adding information of the decoder storage time to the encoded data and transmitting the encoded data added with the information to the terminal, the terminal storing the transmitted encoded data in a buffer thereof during the decoder storage time, and then repeating the storing when the decoder storage time has elapsed.

2. A system comprising: an encoding device that transmits encoded data to a terminal; and the terminal that receives and decodes the encoded data,
wherein the encoding device includes:
a processor configured to execute a process including:
calculating, based on a first system rate that is predetermined and at which data that is encoded in the encoding device is transmitted to the terminal and a second system rate that represents a rate for reproducing the data at the terminal and is calculated based on the data and data used to multiplex and synchronize the data, a decoder storage time; and
adding information of the decoder storage time to the encoded data and transmitting the encoded data added with the information to the terminal, and
the terminal performs storing the received encoded data in a storage area during the decoder storage time and decoding the encoded data when the decoder storage time has elapsed, and then repeats the storing and the decoding.

3. An encoding method comprising:
calculating, based on a first system rate that is predetermined and at which data that is encoded in the encoding device is transmitted to a terminal and a second system rate that represents a rate for reproducing the data at the terminal and is calculated based on the data and data used to multiplex and synchronize the data, a decoder storage time, by a processor; and
adding information of the decoder storage time to the encoded data and transmitting the encoded data added with the information to the terminal, the terminal storing the transmitted encoded data in a buffer thereof during the decoder storage time, and then repeating the storing when the decoder storage time has elapsed, by the processor.

4. A non-transitory computer-readable recording medium storing an encoding program that causes a computer to execute a process comprising:
calculating, based on a first system rate that is predetermined and at which data that is encoded in the encoding device is transmitted to a terminal and a second system rate that represents a rate for reproducing the data at the terminal and is calculated based on the data and data used to multiplex and synchronize the data, a decoder storage time; and
adding information of the decoder storage time to the encoded data and transmitting the encoded data added with the information to the terminal, the terminal storing the transmitted encoded data in a buffer thereof during the decoder storage time, and then repeating the storing when the decoder storage time has elapsed.
