Design Considerations
A DVD Recorder is a consumer video/audio product that can record and play back full-motion video/audio using the ISO MPEG audio/video standards for the compression of video and audio content. The storage media include hard disks and recordable DVD disks.
Core Subsystem include:
Analog Video Decoder - digitizes and decodes baseband analog video formats (NTSC/PAL/SECAM) into digital video.
MPEG Video CODEC/Audio Processor - performs MPEG video encoding/decoding, MPEG audio encoding/decoding, and multiplexing/demultiplexing of the audio and video bit streams.
CPU - controls the DVD Recorder operating system software, overlay of text/graphics, and the user interface.
Triple DAC - convertes digital video into analog video output in different formats: CVBS, S video, RGB, and component video. The output stages require high-performance op-amps to amplify the video signals
Stereo Audio Data Converter - uses audio ADC and DAC to digitize and playback analog audio.
Speaker Driver - includes analog and digital power amplifiers for driving headphone and speakers.
User Interface - allows the user to control the DVD recorder using the panel keypad or the remote control.
Broadband Connectivity - allows streaming audio and video to transmit and receive through ADSL and cable modem.
Power Conversion - converts the input power from the AC adaptor to run various functional blocks.
