The invention relates to the technical field of food processing, in particular to a preserved duck egg preparation technology with goose eggs as raw materials, and the technology comprises the following steps: selecting fresh goose eggs, and carrying out slightly acid cleaning pretreatment; preparing clarified pickling liquid containing tea juice, alkaline substances, table salt and a metal salt hole sealing agent; completely immersing the goose eggs in the pickling liquid, and adopting a segmented variable temperature control strategy of high front part and low rear part; and after pickling is finished, citric acid neutralization deastringency and surface coating preservation are performed. The chemical hole sealing effect of metal ions and the sectional temperature control technology are coordinated and matched, the permeation speed and end point of alkali liquor are effectively regulated and controlled, the phenomenon of head rotting of egg white is thoroughly eradicated, and the finished preserved duck eggs are elastic and moist in egg white, clear in pine pollen, strong in soft yolk and free of pungent and astringent taste; and the yield and commodity value of the preserved goose eggs are obviously improved.

This invention relates to a method for sharing real-time IPTV content to a mobile terminal for playback, belonging to the field of wireless communication and terminals. The method includes: the IPTV device and the mobile terminal sending a STUN request to a public STUN server to bypass NAT and automatically obtain the corresponding public IP address; the IPTV device and the mobile terminal establishing an IPSec encrypted tunnel based on the IPSec protocol; the IPTV device receiving the operator's playback stream, extracting video and audio data, re-encapsulating it into RTP format, encrypting it, and transmitting it to the mobile terminal through the IPSec encrypted tunnel; the mobile terminal decrypting and verifying the integrity of the data packets, extracting the RTP payload, and playing the corresponding video and audio data in real time; the mobile terminal sending control commands to the IPTV device through the IPSec encrypted tunnel; the IPTV device parsing the control commands and calling an API to switch channels, synchronously updating the electronic program guide information to the mobile terminal. This method enables mobile devices to remotely receive and play television channel content from a home IPTV device via the public network, overcoming spatial limitations.
