Problems solved by technology

[0006] However, the existing building intercom system equipment is diverse and complex, including door phones, fence phones, management centers, indoor extensions, central switches, networking switches, and floor switches. It is necessary to lay an independent line to form a system for the equipment. RVV line transmits audio and data, SYV line transmits video
It is two different networks from the fixed telephone system, which to a certain extent causes redundant construction of lines and low equipment utilization

Embodiment Construction

[0031] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0032] Fixed-line network (PSTN: Public Switch Telephone Network), that is, the fixed-line telephone network commonly used in our daily life; PSTN has the advantages of stable signal transmission, clear sound quality, strong anti-lightning strike, and strong anti-interference performance. The signal and control signal are transmitted through the fixed-line network to improve the stability and anti-interference of the building intercom signal during transmission.

[0033] see Figure 1A and Figure 1B , is a schematic structural diagram of the building video intercom system in the first embodiment of the present invention.

[0034] Building visual intercom system, including PSTN network for transmitting audio signals and control signals, ...

Abstract

The invention discloses a building visual intercom system. In the system, audio and data signals are transmitted by the existing PSTN (public switched telephone network), and video signals are transmitted to an indoor machine through a video transmission network. The system only needs the single distribution of SYV lines for transmitting video signals, the repeated building of transmission lines is avoided, and the utilization rate of equipment is improved. The invention simultaneously discloses a method for carrying out audio processing on the building visual intercom system and a method for carrying out audio and video synchronous processing on the building visual intercom system.

Description

technical field [0001] The invention relates to communication equipment, in particular to a building visual intercom system and an audio processing method and an audio and video synchronization processing method for the system. Background technique [0002] Human society has entered the information age, various information transmission carriers are constantly emerging, and the competition in information channels is also intensifying. However, the landline telephone, the earliest major communication tool used by human beings, has not been able to regain its former glory. [0003] According to the "National Telecom Industry Operation Situation from January to May in 2010", in May 2010, the number of telephone subscribers nationwide increased by 7.788 million, and the total number exceeded 1.1 billion, reaching 1,101.837 million, of which fixed telephone subscribers decreased by 1.627 million. The number reached 305.922 million, with a net increase of 9.414 million mobile phon...
