Multimedia Signal Processing in
Wireless
With the exponential
growth of wireless voice markets, demand for wireless video services
is soon to follow. However, bandwidth limited wireless channels
coupled with mobility issues pose a great challenge in the hardware,
software and algorithm design of communication systems. Raw video
transmission is a high bandwidth application due to its spatial and
temporal redundancies. Hence effective video communication over
wireless channels calls for intelligent video coding and protection
schemes. Also, the real-time nature of video necessitates high
performance hardware and efficient software. A modular and
standards-independent DSP-based platform can be designed for real-time
video communication over low-bandwidth channels, which makes it
possible for real-time transmission of MPEG-4 video and JPEG2000 still
images over the Bluetooth wireless standard. Such a demonstration has
many potential applications. To explore the possibilities, demands,
and challenges of real-time wireless video transmission, we can
implement the MPEG-4 and JPEG2000 source coding on DSP platforms like
Texas Instruments (TI) TMS320C6211 OR TI TMS3206416.
