ABSTRACT:
An encoded multimedia terminal having a low cost decompression circuit together with a low cost interconnect circuit coupled to a powerful server. The terminal can accept user input via a mouse, keyboard, remote control, or handset. In one embodiment, the server has ports which provide real-time audio and video encoding of source material based on user edits and the original source. An encoded bitstream is then sent to the encoded multimedia terminal for decoding. Broadly speaking, the present invention contemplates an encoded multimedia terminal comprising a microcontroller, a network interface, a multimedia bitstream decoder, and a display controller. The microcontroller receives input from a user-input device and responsively determines a user input signal. The network interface is coupled to the microcontroller to receive the user input signal and is configured to communicate the user input signal to a multitasking server which is executing a software application. The software application accepts the user input signal and responsively updates a video display, and the multitasking server converts the video display to a multimedia bitstream and communicates the multimedia bitstream to the network interface. The multimedia bitstream decoder is coupled to the network interface to receive the multimedia bitstream and is configured to convert the multimedia bitstream into a digital video signal. The display controller is coupled to the multimedia bitstream decoder to receive the digital video signal and is configured to responsively provide a display signal to a display screen. The multimedia bitstream may be DVD-compliant.
