Decoding chip:
Mt8580 mainly includes Video Decode, Audio Processing, Memory Controller, HDMI transmitter, servo
Processing, External Interface, HDMI Receiver modules.
Mt8580 can support BD, DVD, and CD playback, including the latest BD-ROM formats, such as BD-Live
and BonusView. It features AVC, VC1, and MPEG-2 video decoders that can decompress full high-
definition video streams. And for audio decoding, its multi-format decoder is capable of decoding Dolby
TrueHD and DTS-HD lossless audio.
MT8580 is fabricated with advanced silicon process and offers higher CPU performance and more
DRAM bandwidth. This SoC also includes a powerful graphics engine and a variety of peripherals,
including USB 2.0 ports. To support popular network applications, MT8580 also implements 10/100
Ethernet interface and support WLAN connection thru its USB port.
Besides the connectivity features, audio and video output quality and flexibility is another focus of state-
of-the-art Blu-ray devices. MT8580 embeds 4 channels of 148MHz/12-bit video DAC and also an HDMI
1.4 compliant transmitter for 2D/3D video output. And MT8580 also embeds an HDMI 1.4 Receiver for
video input. Its audio output via I2S, SPDIF and HDMI can be configured independently. Moreover,
MT8580 also supports audio bit stream input from HDMI and SPDIF, which is a key function in the growing
Blu-ray HTiB segment
