Product Brief

Features Description (continued)

Audio

MPEG Video Encoder

• Dolby Digital Consumer Encoder, MPEG Audio Encoding with

Programmable Audio DSP

• Input Digital Audio: 2ch, 16-bit, 32/44.1/48kHZ

• Output via I2S interface: 5.1+2ch, 24-bit, up to 192kHz

• Output Analog Audio: stereo class D outputs

The MPEG Video encoder supports real-time encoding into MPEG-2

formats. With programmable spatial and temporal preprocessing

filters, the user can shape the incoming video to optimize the MPEG

encoding. The horizontal decimator allows for a wide range of

horizontal encoding resolutions: 352, 360, 480, 544, 704, and 720.

Programmable horizontal resolution, along with the bitrate, provides

great flexibility in optimizing the encoded video quality versus storage

time. The encoder supports recording of 2/4/6/8 hours on a single

layer DVD+/-R disc.

Graphics

• High quality 16bpp OSD

• 4bpp alpha transparency

Automatic scene change detection and variable/constant bit rate

processing consistently deliver optimal video quality over a variety of

input video quality and content during encoding
