Abstract

The invention relates to a device and a method for monitoring mobile phone video based on optimized H.264 coding standard. The method comprises the following steps: carrying out digitized sampling on acquired audio signals and video signals respectively; carrying out de-noising processing on the video signals, compressing video data by adopting an optimized H.264 compression algorithm, compressing audio data by adopting an optimized AMR algorithm, and overlapping channel number, monitoring date and time into the compressed audio-video data; and sending the compressed audio-video data to a mobile phone terminal through RTP and RTSP protocols, and playing the audio-video signals through corresponding player software. The device and the method adopt a holing mode facing private network TCP penetration, and have functions of reliable monitoring for a multi-frame differential moving target, advanced image record based on a double-buffer area, private area protection, multi-language automatic switch, wire/wireless automatic detection, audio bidirectional talkback based on a TCP5000 port and automatic alarm.

Description

technical field [0001] The present invention relates to mobile phone video monitoring, more specifically, relates to a mobile phone video monitoring device and method based on the optimized H.264 encoding standard. Background technique [0002] H.264 is a high-performance video codec technology. The biggest advantage of H.264 is that it has a high data compression ratio. Under the condition of the same image quality, the compression ratio of H.264 is more than 2 times that of MPEG-2, and 1.5 to 2 times that of MPEG-4. At the same time, H.264 has high-quality and smooth images while having a high compression ratio. [0003] At present, known camera devices all adopt wired transmission based on coaxial cables or 2.4GHZ wireless communication methods, which can only transmit distances of several hundred meters, which limits the range of use. And the QQ camera device that supports remote video transmission needs the support of computer and its related software, which is very i...
