Philips Semiconductors’ second generation real time
MPEG-2 encoder, the SAA6752HS, is a highly integrated
single-chip audio and video encoding solution with flexible
multiplexing functionality. With our expertise in two critical
areas for consumer video encoding, noise filtering and
motion estimation, we have pushed the boundaries for
video quality even further, providing enhanced quality for
low bit rates and enabling increased recording times for a
given storage capacity. The SAA6752HS will also enable
a key driver for new consumer digital recording
applications and system cost reduction. By integrating all
audio encoding and multiplexing functionality we will be
moving from a three chip to a one chip system, with cost
efficient design and process technology, thus providing a
truly low cost, high quality encoding system.
The SAA6752HS/V104 is intended for customers whose
application does not require the DDCE function.
The SAA6752HS gives significant advantages to
customers developing digital recording applications:
(1) MIPS is a registered trademark of MIPS Technologies.
Fast time-to-market and low development
resources. By adding a simple external video input
processor IC, an audio analog-to-digital converter, and
an external SDRAM, analog video and audio sources
are compressed into high quality MPEG-2 video and
MPEG-1 layer 2 or AC-3 audio streams, multiplexed into
a single program or transport stream for simple
connection to various storage media or broadcast
media. Hence, making design effort for our customers a
minimum, as well as removing the need for in-depth
experience in MPEG encoding.
Low system host resources. All video and audio
encoding algorithms and software are run on an internal
MIPS
small amount of communication from the system host
processor to set up and control required encoding
parameters via the I
