ES7020
Vantage-II Audio/Video Codec
Product Brief
ESS Technology, Inc.
DESCRIPTION
FEATURES
• MPEG-2 video encoding up to MP@ML.
• Constant and variable bit rate (CBR/VBR) encoding.
• Inverse 3:2 pull-down.
The ES7020 Vantage™-II codec is a highly integrated
superior performance chip that combines an advanced
MPEG-2 decoder with a sophisticated MPEG-2 encoder
and an NTSC/PAL encoder. The ES7020 provides time
base correction (TBC) for recording from VCR
videocassette tapes with weak signals without loss of
synchronization, low delay monitoring of decoded video
output signal, ATAPI interface, built-in CPRM encode/
decode, state-of-the-art progressive-scan video, and S/
PDIF input and output support.
• Built-in time base corrector (TBC).
• Frame mode and field mode encoding.
• Vertical blanking interval (VBI) data slicer.
• CPRM encryption.
• ATAPI Interface with control for up to two storage media
devices, such as hard disk drives, A/V recordable
loaders, and Flash memory cards.
The MPEG encoder portion does flexible NTSC or PAL
encoding on a YUV 4:2:2 stream in response to firmware
control of the internal CPU. The internal CPU, in
conjunction with an additional hardware accelerator,
allows for very flexible encoding and allows for additional
functionality to be easily added. An audio DSP engine
facilitates the encoding of MPEG-1 layer 2 audio while the
host CPU interface unit allows for easy reading of close
caption data. In addition, the ES7020 has inverse 3:2 pull-
down capability, allowing it to dynamically analyze
incoming fields and compress from 60 fields to 24 frames
in the case of film material.
• 4x-8x high speed archiving over ATAPI interface to
storage media, such as a hard disk drive to DVD+RW or
DVD-RW disc.
• Real time clock.
• On-chip modem with integrated low voltage DAA.
• Integrated NTSC/PAL encoder with pixel-adaptive de-
interlacer and five 10-bit 54MHz video DACs.
• High-quality progressive scan video output for flicker-free
video display.
• DVD-Video, DVD-VR, VCD and SVCD playback.
• Media playback with CD-ROM, CD-R/RW, DVD-R/RW,
The MPEG decoder portion is built on the ESS proprietary
dual CPU Programmable Multimedia Processor (PMP),
consisting of a 32-bit RISC processor and a 64-bit vector
engine. This architecture is extremely programmable and
allows for the best DVD feature set. The RISC processor
performs bit stream parsing, transfers data to the vector
engine, and manages the chip as a whole.
DVD+R/RW, and DVD-RAM.
• Up to 7.1 channel audio outputs.
• Bass management.
• Direct 8/16-bit SDRAM interface up to 16 MB capacity.
• Macrovision 7.1 for NTSC/PAL interlaced video or
progressive (480p/576p) video.
• Composite, S-video, and CCIR656 video outputs.
The vector engine performs all the computationally
intensive tasks required by applications such as Dolby®
Digital, DTS Surround™, and MPEG and JPEG imaging.
These tasks include video motion compensation and
estimation, loop filtering, discrete and inverse discrete
cosine transforms (DCT/IDCT), quantization, and inverse
quantization.
• OSD graphics plane with 256 colors and eight levels of
transparency.
• ESS Music Slideshow ™
• S/PDIF digital audio input and output.
• MP3, MPEG AAC, and WMA digital audio decoding.
• Dolby Digital, Dolby Pro Logic™, Pro Logic II digital audio
The ES7020 with DTS support is offered with the
ES7020D, which has the same pinout as the standard
ES7020. The ES7020 and ES7020D are available in an
industry-standard 388-pin BGA package.
decoding.
• DTS Surround and DTS ES digital audio decoding
(ES7020D only).
• Lead-free leads using 98%-Sn/2%-Cu or 98%-Sn/2%-Bi.
