Digital Frame Storage for Television Video
Storage of a full frame of quantized television video using an all-digital memory has now become practical, thanks to the steady increase over the past few years of the data-rate capabilities of MOS shift register devices (now 5–8 MHz) accompanied by decreasing costs (now less than 0.4 cents per bit). The primary advantages of a digital frame store with real-time input/output capability are flexible data rate (as opposed to the fixed rate of a video disc) and long-term stability (as opposed to storage tubes). The recently-built system described in this paper utilizes digital frame storage to provide a flexible interface between standard television video, an Electron Beam Recorder using non-interlaced scanning, and a computer with a relatively slow input and output rate.
