What makes Dr. TV work Dr. TV is a new DRM application. It is What makes Dr. TV work Dr. TV is a new DRM application. It is made possible by enhancement of the Coder (Content. Server) and Decoder (Receiver) and enlargement of the transmitter bandwidth to 20 k. Hz. To receive and play Dr. TV, the receiver (like Uniwave) must have enough CPU power (Central Processing Unit) to be able to decode DRM 20 k. Hz bandwidth. The receiver must be able to convert and display the picture stream on the monitor. January 10 The CPU of an Intel micro-processor
