A device for audio and video playback is operable to receive a digital video signal input or an analog video signal such as a National Television System Committee-standard (NTSC) video signal input through an input connector port of the device. The device may also receive an audio signal input through an audio input connector port. The audio and video playback device includes a storage device for storing audio and video signals in Moving Picture Experts Group-standard (MPEG) format. The audio and video playback device also includes output connector ports operable to provide audio output and video output. A central processing unit in the device receives audio and video input signals from the input connector ports, compresses the audio and video input signals into MPEG format and can store the MPEG-format signals in the storage device. The processor is also operable to retrieve and decompress stored audio and video signals from the storage device and provide output signals to output connector ports.
