AI Technical Summary

Technical Problem

Existing IPTV systems cannot enable secure, low-latency remote access to home IPTV devices from mobile terminals, and suffer from problems such as network dependence, fixed equipment, insufficient transmission security, and difficulty in network penetration.

Method used

By combining the STUN client with the IPSec protocol, NAT traversal and encrypted tunnel communication between devices are achieved. The public STUN server works with IPTV devices and mobile terminals to obtain public network addresses, and an encrypted tunnel is established based on the IPSec protocol for data transmission, ensuring security and low latency.

Benefits of technology

It enables secure, low-latency communication between mobile terminals and home IPTV devices, overcomes spatial limitations, adapts to resource-constrained devices, reduces deployment costs, ensures the security of transmitted content, and enhances user experience.

Abstract

The invention relates to a method for sharing an IPTV (Internet Protocol Television) real-time picture to a mobile terminal for playing, which belongs to the field of wireless communication and terminals, and comprises the following steps: an IPTV device and a mobile terminal send an STUN request to a public STUN server, penetrate through an NAT (Network Address Translation) device and automatically obtain a corresponding public network address; the IPTV equipment and the mobile terminal establish an IPSec encryption tunnel based on an IPSec protocol; the IPTV equipment receives the service provider playing stream, extracts video data and audio data, repackages the video data and the audio data into an RTP format, encrypts the video data and the audio data, and transmits the video data and the audio data to the mobile terminal through an IPSec encryption tunnel; the mobile terminal decrypts and verifies the integrity of the data packet, extracts the RTP load, and plays corresponding video data and audio data in real time; and the mobile terminal sends a control instruction to the IPTV equipment through the IPSec encryption tunnel, and the IPTV equipment analyzes the control instruction, calls the API to switch the channel and synchronously updates the electronic program guide information to the mobile terminal. According to the method provided by the invention, the mobile equipment can remotely receive and play the television channel content of the family IPTV equipment through the public network, and the space limitation is broken through.
