The HD-SDI/SDI high-definition digital optical terminal manufactured by Beijing Huachuang Shitong Technology Co., Ltd. can transmit high-definition signals up to 1080P, which meets the demand of broadcasting and television industry for transmitting high-definition video signals. At present, the product has been successfully applied to some TV stations nationwide, and its product performance has been recognized.

I. scope of application of high standard equipment

HD/SD equipment is mainly used to achieve long-distance lossless transmission of digital video signals, the premise is that the signal source is high-definition or SD signal source, so generally HD/SD equipment front-end encoder or HD camera, and then back-end encoder for editing.

HD-SDI/SDI often uses two scenarios:

1, live broadcast.

2, the connection before the digital studio video recording and broadcasting equipment.

For example:

1. Live broadcast of TV sports events, large outdoor entertainment activities and radio and TV programs.

2. Transmission and retransmission of signals between the same TV program in two venues.

3, different provincial TV stations jointly produce on-site activities.

4, school auditorium or venue production, recording and broadcasting.

At present, in addition to the radio and television industry, there are also some customers in the field of monitoring need our equipment to monitor important occasions, this should be a trend in the future.

For the analog video signal and broadcasting audio that the broadcasting industry needs to transmit, we can also use our broadcasting audio and video optical terminal to realize the transmission of analog signals.

Broadcast devices usually have access to the front and rear ends.

Front-end devices include: satellite receivers, VCR, DVD, video cameras, etc.

Back-end devices: video recorders, coding systems, coding, modulators, satellite modulators, and microwave elimination

Common scenarios for broadcast level audio and video terminals are:

1, the use of cable TV network.

2, the exchange of provincial, city and district TV programs.

3. Video exchange between enterprises, factories, mines and military units

4, the Beijing music of parks and stadiums.

5. Campus broadcasting
