Technical field
The utility model relates to a kind of video frequency transmitter, more particularly, relates to a kind of video transmission server.
Background technology
Video monitoring has had very long developing history as a kind of important security protection means; At present, video monitoring is used more and more widely in every field such as education, traffic, video, health quarantine, customs, the energy, finance, national defence, and the video monitoring technology becomes one of most popular security and guard technology undoubtedly.
Along with development of science and technology, video monitoring is gradually from digitlization, simulated to networking, high Qinghua, intelligent direction development; Along with continuing to optimize of Network Video Surveillance product image definition, the also more and more strictness of bandwidth environment that the supervisory control system transmitting video-frequency flow is required; Image is clear more, and the required bandwidth condition of transmitting video-frequency flow is also just high more.
Domestic, external big security protection enterprise all for how solving this problem of bandwidth environment is working hard.Such as: the front end video is adopted compressed format more efficiently, and abroad from MPEG-1 to MPEG-4, domestic then from H.261 developing into present main flow H.264, the progress of every kind of compressed format has all promoted several times of radixes with compression efficiency.
In the video transmission process, the definition of transmission of video images is also relevant with multiple restrictive conditions such as bit rate, code streams; Bit rate is meant bit (bit) number that per second transmits.Unit is bps (BitPerSecond), and bit rate is high more, and the data of transmission are big more.Bit rate representes need represent with what bits each second through sound, video data behind the coding (compression).The relation of bit rate and sound, video compression briefly is exactly that bit rate is high more, and the quality of sound, video is just good more, but the file behind the coding is just big more; If situation is just opposite at least more for bit rate.
Code stream (DataRate) is meant the data traffic that video file uses in the unit interval, also be code check, is most important parts during image quality is controlled in the video coding.Under the same resolution, the code stream of video file is big more, and compression ratio is just more little, and image quality is just high more.
Therefore in order to solve bandwidth problem, existing video server is also needed the frame per second that effective technical means reduces images badly except the video coding technique that adopts high compression.
