One way to think of slow-scan television (SSTV) is to imagine fast fax An SSTV signal, like a fax signal, is sent within a band of frequencies as narrow as that of a human voice And, like fax, SSTV transmission is of still pictures, not moving ones The big difference between SSTV and fax is that SSTV images are sent in much less time The frame time is 8 seconds, rather than several minutes This speed bonus comes with a tradeoff: lower resolution, meaning less fineness of detail The resolution of an SSTV image is a bit less than that of an ordinary television picture All SSTV signals are received on cathode-ray-tube (CRT) displays A computer can be programmed so that its monitor will act as an SSTV receiver Converters are also available that allow SSTV signals to be viewed on a consumer type TV set An SSTV frame has 120 lines The black and white frequencies are the same as for fax transmission; the darkest parts of the picture are sent at 15 kHz and the brightest at 23 kHz Synchronization (sync) pulses, that keep the receiving apparatus in step with the transmitter, are sent at 12 kHz A vertical sync pulse tells the receiver it s time to begin a new frame; it lasts for 30 milliseconds (ms) A horizontal sync pulse tells the receiver it s time to start a new line in a frame; its duration is 5 ms These pulses prevent rolling or tearing of the image Ham radio operators like to send SSTV with SSB transmitters It s also possible to transmit SSTV using AM, FM, or PM But these modes take up more spectrum space than SSB An SSTV signal, like a fax signal, can be sent over the telephone This puts the video phone within reach of current technology, and the equipment isn t too expensive Although the images don t convey movement, because the frame time is long, telephone SSTV lets you see people on the other end of the line, and also lets them see you The bugaboo is that the other person or you might not want to be looked at The camera can be switched off easily enough And, as often as not, users of video phones prefer it that way. itext java lang illegalargumentexception pdfreader not opened with owner password: Adobe LiveCycle * Removing Password Encryption remove password from pdf using java unlock protected pdf files - Stack Overflow
