Introduction
This scheme combines the actual needs and technical characteristics of public security and procuratorate interrogation and inquiry. It adopts advanced H.264HP digital video processing technology. Video can be coded and decoded up to 1080P60 in both mainstream and auxiliary channels at the same time. Audio can support AAC-LD broadband encoding. It provides CD-level sound quality and significantly improves the sense of interaction and fidelity. The system uses high-performance digital signal processing chip, which has very low power consumption and ensures the long-term stable operation of the product without fault. In order to realize the sharing of electronic evidence in remote interrogation, the recording of the process of interrogation, live broadcasting and on-demand broadcasting of cases, the integrated comprehensive interrogation not only achieves the fairness and efficiency of interrogation from a macro perspective, but also makes more efficient use of "fragmentation" time for case handlers from a micro perspective, so that our case handlers and policemen can devote more time and energy to case review. Evidence analysis itself, so as to effectively improve the quality and efficiency of handling cases.

 
Features
1080P60 HD Experience
In the design and implementation of the system, the full HD design of HD acquisition, HD coding and decoding, HD transmission and HD display is realized. In the process of interrogation, the subtle differences of various objects, characters and components can be displayed vividly on the remote screen, which strengthens the effect of face-to-face interrogation and provides interrogation level.
High fidelity audio effect
The system supports broadband audio coding technologies such as G.711, G.722, G.722.1C and AAC-LD, supports voice processing technologies such as automatic echo cancellation (AEC), automatic noise suppression (ANS) and automatic gain control (AGC), performs high fidelity digital processing and intelligent mixing, provides professional audio effects, and makes the voice sound clearer, fuller and richer.
Dual Stream for Demonstration
The guards show that there are single-screen, double-screen, single-screen, three-screen and so on. In addition, the size of the picture can be interchanged, and the layout of various pictures can be flexibly switched.
Open platform, interconnection and networking
The interfaces of all the equipments used in the system are all standard interfaces, which follow the international standard agreement. Besides, it also provides rich API, development documents and DEMO to support the rapid development of classroom control form.
Pure hardware architecture
Every key link of the system is implemented by pure hardware architecture, which has better mutual effect and stronger stability.
