COMMUNICATION SYSTEM, INFORMATION PROCESSING APPARATUS, COMMUNICATION METHOD AND PROGRAM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240056288 titled 'COMMUNICATION SYSTEM, INFORMATION PROCESSING APPARATUS, COMMUNICATION METHOD AND PROGRAM

Simplified Explanation

The communication system described in the patent application includes an information processing device that offers a video conference service. Communication terminals utilize this service. The information processing device encrypts and transmits communication data from each communication terminal, storing it in a first storage. It also sends a ciphertext to the communication terminals, which is an encryption key capable of decoding the communication data in the first storage. The communication terminals decode the communication data using the ciphertext and reproduce the video and audio content in synchronization with others based on control data in the communication data.

  • The patent application describes a communication system that provides a video conference service.
  • Communication data from each communication terminal is encrypted and stored in a first storage.
  • An encryption key, capable of decoding the communication data, is transmitted to the communication terminals.
  • The communication terminals decode the communication data using the encryption key.
  • The decoded communication data includes video and audio content, which is reproduced in synchronization with others based on control data.

Potential Applications:

  • Video conferencing systems for remote communication.
  • Secure transmission and storage of communication data.
  • Collaborative work environments where synchronized video and audio are essential.

Problems Solved:

  • Ensures the privacy and security of communication data through encryption.
  • Facilitates the decoding and reproduction of communication data by providing an encryption key.
  • Enables synchronized playback of video and audio content in a video conference.

Benefits:

  • Enhanced privacy and security of communication data.
  • Efficient decoding and reproduction of communication data.
  • Improved synchronization of video and audio content in a video conference.


Original Abstract Submitted

a communication system includes an information processing device that provides a video conference service; and communication terminals using the service. the information processing device records communication data related to a video conference encrypted and transmitted from each communication terminal in a first storage for the communication terminal; transmits, to the communication terminals, a ciphertext obtained by encrypting an encryption key capable of decoding each item of the communication data recorded in the first storage such that the encryption key can be decoded by the communication terminals; and transmits the communication data recorded in the first storage to the communication terminals. each communication terminal decodes the communication data for the communication terminal using a decoding result of the ciphertext; and reproduces video and audio included in the communication data decoded for the communication terminal in synchronization with the others based on control data in the communication data.
