Overview
H.264 Advanced Video Coding (AVC) is the latest and most
advanced video coding standard recommended by ITU &
ISO. It contains a rich set of video coding tools to support
a variety of applications ranging from video conferencing,
digital broadcast, to digital storage media. Subsets of
coding tools are defined as profiles. The most widely used
profiles are Baseline Profile (BP), Main Profile (MP) and
High Profile (HP).
H.264
Baseline Profile Encoder
H.264 Baseline Profile has the advantages of high
coding efficiency, low latency, low complexity and low power
consumption. It has been widely adopted for the conversational
services which operate typically below 1 Mbps with low latency
requirements such as video conference, wireless streaming
services, MMS/Video Mail, etc.
System
Requirements
ASTRI H.264 Baseline Profile Encoder software solution
requires an embedded CPU system running on the ARM926EJ-S
(160MHz) platform with 32K I-cache and 16K D-cache. Memory
requirements are 110KB ROM and 600KB RAM. |
