Communication apparatus, communication system, communication method, and recording medium

A communication system comprising circuitry to:

• acquire receiver side environment information indicating a communication environment of the counterpart communication apparatus that receives content data from the communication apparatus;
• determine a number of layers of the content data for scalable coding, based on the receiver-side environment information;
• code the content data in the determined number of layers by using the scalable coding;
• and
• transmit the coded content data to the counterpart communication apparatus through a communication network.

A method of controlling communication of a communication apparatus with a counterpart communication apparatus, the method comprising:

• acquiring receiver-side environment information indicating a communication environment of the counterpart communication apparatus that receives content data from the communication apparatus;
• determining a number of layers of the content data for scalable coding, based on the receiver-side environment information;
• coding the content data in the determined number of layers by using the scalable coding;
• and
• transmitting the coded content data to the counterpart communication apparatus through a communication network.
