Abstract
An improved electronic solid-state record/playback device (SSRPD) and electronic system may be used to record and playback information such as audio, video, control, and other data. The SSRPD uses no tape or moving parts in the actual record/playback process but includes an audio and/or video and/or other data record/playback module (RPM), which performs all of the record signal conversion, recording and data compression algorithms, digital signal processing, and playback signal conversion. The SSRPD has program input processing and control output processing modules so that other devices may be controlled in different ways including interactive control. A time and control processor module facilitates internal synchronization of the SSRPD audio, video, and control information, as well as synchronization with other devices. The SSRPD information described is recorded into an internal resident memory(s). The novel interface allows information to be exchanged without degradation via a digital Portable Storage Device (PSD) which may be a Random Access Memory card (RAM card), with other SSRPDs as well as to a special Computer Interface Device (CID). The CID is an intelligent device that …
