Description
MPEGS422 Professional Studio Encoder
MPEGS422 Professional Studio Encoder maintains IBM’s leadership position in 4:2:2 profile applications and
addresses the special needs of high quality applications. The chip supports MPEG-2 IBP encoding for 4:2:2
Profile at Main Level and compressed data rates up to 50 Mb/s. It maintains this conformance with a search
range of +/-101H, +/-64V.
MPEGS420 Professional Broadcast Encoder
IBM’s MPEGS420 Professional Broadcast Encoder provides real-time 4:2:0 MPEG-2 encoding at CCIR601
resolution. The MPEG420 offers high performance and functionality at a search range of +/- 101H, +/-64V
and data rates up to 50 Mb/s. The MPEGS420 can also be congured by the user for 15Mb/s (or less) com-
pressed data rates, and for a search range of +/-64H, +/-56V. This allows ASRAM to replace SSRAM on the
search memory interface. User selectable chrominance down sampling from 4:2:2 and 4:2:0 in either pro-
gressive or interlaced mode assures color quality.
MPEGSI Intra-Frame Encoder
IBM’s MPEGSI Intra-Frame Encoder offers the flexibility and editability of an intra-frame bitstream along with
the excellent picture achieved through many of the rate control features available on the MPEGS422 product.
Image statistics and user-specified encoding functions combine to produce high quality images at rates of up
to 50Mb/s. The MPEGSI is a low power solution, well suited for applications with high picture quality and min-
imal hardware requirements.
