Title: Innovations by Song Qiu in Video Technology

Introduction

Song Qiu is a notable inventor based in Beijing, China, recognized for his contributions to video technology. He holds three patents that showcase his innovative approaches to video encoding and security systems. His work has significantly impacted the way video data is processed and transmitted.

Latest Patents

One of Song Qiu's latest patents is a video codec method and system. This invention discloses techniques pertaining to scalable video codecs. It involves analyzing a video image to identify a region of interest (ROI) and a region of non-interest (non-ROI). By comparing the non-ROI image with a previous image, a background ignored identifier is created, indicating whether the non-ROI can be ignored during encoding and decoding processes. The encoder then encodes the images into a basic layer (BL) and an enhanced layer (EL), transmitting the coded bit streams along with the identifier to a decoder. The decoder reconstructs the image based on the identifier and the BL and EL bit streams.

Another significant patent by Song Qiu is a video monitoring system with encrypted video signals. This invention establishes secured communication of video data between a monitoring system, which includes a monitoring camera and a monitoring terminal, by encrypting the video data. The monitoring camera encrypts digital image data before transmission to the monitoring terminal. Instead of using commonly employed encryption schemes, encryption rules are generated according to an encryption key corresponding to a predetermined encryption algorithm. On the monitoring terminal side, decryption rules are generated based on a received description key corresponding to a predetermined decryption algorithm.
