5120 video networking codec from LSI Logic is the
industry鈥檚 first full-duplex, real-time, MPEG-2 codec engine. It is specifically
designed to meet the quality and performance requirements of today鈥檚
latency-sensitive enterprise video networking systems. Combining ultra-low-
delay compression technology with the space and cost savings of a single-
chip design, the DVxpert 5120 delivers broadcast-quality MPEG-2 video that
is far superior to video networking based on H.32x standards.
The DVxpert 5120 leverages the MPEG-2 Main Level @ Simple Profile
(ML@SP) codec standard to achieve end-to-end delays of less than 100 ms.
The DVxpert 5140 is a superset of the DVxpert 5120 that provides several
options to the video compression solution for networking. For half-duplex
video communications applications where full resolution picture quality is
an absolute must (such as distance learning or corporate communications),
DVxpert 5140 offers the ability to MPEG- 2 compress video at 鈥渇ull D1鈥?/div>
resolution at bit rates from 2 to 10 Mbps.
TARGET APPLICATIONS:
DVxpert 5120/5140 it the most flexible solution available on the
market today:
鈥?MPEG-2 鈥淔ull D1鈥?compression up to 10 Mbps
鈥?MPEG-2 鈥?/2 and 2/3 D1鈥?compression up to 15 Mbps
鈥?MPEG-2 ML@SP compression/decompression up to 15 Mbps
鈥?MPEG-1 compression 56 kbps to 5 Mbps
8MB of SDRAM
The DVxpert 5120/5140 codec sup-
ports a wide range of high-quality
video applications, including:
鈥?Video networking
鈥?Professional conferencing
鈥?Distance learning
鈥?Interactive desktop video
