Panovel Demonstrates iStream Wireless HD Video Technology for HD Video Streaming

Panovel Technology Corporation today demonstrated its wireless HD Video
Streaming Solution. The solution is based on Panovel’s
iStream technology which has been incorporated into Panovel’s new highly
integrated single-chip SoC, the PN101. The solution allows wireless HD
multimedia streaming and sharing amongst multimedia devices such as battery
operated handheld smartphones, camcorders,
cameras, and other power sensitive devices with very low latency and superior
throughput thus delivering very high quality video and user experience.

The PN101 is a feature-rich, single-chip solution enabling OEMs to develop
and offer cost-effective, feature-laden products to the consumer capable of
wireless HD video streaming and
sharing. Panovel’s iStream features patented low latency scheduling
technology for video streaming and interactive gaming applications, a two level
scheduler for efficient utilization of bandwidth, with the lower level scheduler
hardware accelerated. For throughput and efficiency optimization, iStream
utilizes an array of advanced technologies including a patented packet
aggregation/error mitigation algorithm, optimized sliding window
implementation, deep hardware acceleration of MAC, and IO integration with data

Panovel designed for power and cost savings from the outset, optimizing from
system/architecture level to every critical block to achieve its goals. For
example, its two layer intelligent memory management method allows support of HD
video streaming without the need for external memory. Further cost and power
savings are achieved by implementing a mixed-signal, single-chip design in low
power CMOS process technology with integrated 3-8GHz RF capable of 500MHz
bandwidth per channel and sustained data rates of 200Mbps.

"Unlike 802.11n-based solutions, which utilize CSMA protocol, Panovel chose
TDMA protocol. "We chose TDMA because it meets the higher QoS requirements of
wireless HD video streaming. TDMA provides a connection oriented, very low
latency, dedicated bandwidth resulting in a superior predictable end user
experience than 802.11. On the contrary, 802.11n cannot control the latency, the
key QoS requirement for wireless HD video, in the congested unregulated ISM band
due to interference from heavily deployed 802.11a/b/g devices, Bluetooth
devices, and even home appliances devices like microwave," explained company
founder, Junfeng Wang. "We believe our iStream technology will do for
wireless HD multimedia, what Bluetooth did for audio media 10 years ago."
