This fiber optic product Video+Audio+Data Multiplexer relates generally to telecommunications systems, for example cable, television, video and satellite broadcasting; printers; scanners (such as those utilized in photocopiers, facsimile machines and the like); recording and storage media; and like devices capable of producing a raster scan. It particularly concerns efficient methods and systems for simultaneous digital compression of video, audio and/or data (VAD) signals to preselected examples of compression, to be used in military intelligence and civilian applications.
Why was Video Audio Data Multiplexer invented? It is the background here. In a video and audio multiplex recording apparatus, an allocation table of your unit video block along with a unit audio block is generated in the control section, along with a control signal is generated according to the allocation table. Multiplexing data of the data structure by which each unit video block matches each unit audio block in 1 to 1, is outputted from your multiplexer based on the control signal. Accordingly, the correspondence with the audio data for the video information is distinct, and the audio insert can be conducted. Further, as the data structure that isn't discontinuous at first part of the overwrite from the audio data, is formed in line with the allocation table, thereby, the audio insert in which noises do not occur during the time of reproducing, may be conducted, and also the fine quality audio editing can be conducted.
Analog baseband video and analog audio signals are often transmitted and received via separate channels. Common examples will be the familiar standard television monitors, video tape recorders, and video cameras. It's well known that standard television broadcast and cable signals include a separate frequency modulated radio frequency carrier just above the companion video band, where the total channel bandwidth is 6 megahertz. Current activity concerning the state of television and video art is focused primarily on digital techniques. Video has created great strides in laptop or computer displays, and has made some practical advances in satellite broadcasting, however, increased bandwidth requirements (steer clear standing costly data compression techniques) and relatively high expense have yet to be overcome if broad public acceptance will be achieved.
And it's instructive to remember that during the computer networking environment, where digital video is king, video communications (as an example, video conferencing) remains of poor quality at best due to bandwidth limitations in conjunction with the shortcoming of current data compression strategies to overcome these limitations. Furthermore, video traffic usually brings other network activity to a standstill as a result of large information load that video places of all computer networks. Perhaps the greatest impediment to video transmission on computer networks may be the cost factor. The cost of every digital video product currently available for computer networks is so high that it is hopelessly away from line with what users anticipate paying in accordance with what they are accustomed to paying for other capabilities at hand.
So this invention Video Audio Data Multiplexer addresses baseband audio/video signal transmission. Particularly, it possesses a way to either transmit or receive both audio and baseband video signals on a single channel, for instance a transmission line, without worrying about yet another audio carrier, including the standard 5.7 megahertz broadcast carrier or perhaps the 10.7 megahertz intermediate frequency carrier. Additionally, it offers the transmission of ancillary information, such as alphanumeric data, or command streams for handheld remote control, via judicious allocation of that time period and bandwidth available in the recording signal profile.
