Wireless video
In parallel with the 802.11 stream of standards, there has been a steady march of Wireless personal area networks towards the 60 Ghz ISM band as well. In particular the requirements of being able to develop a wireless video area network for full HD resolution leads towards similarly high data rate requirements.
The latest Wireless HD 1.1 standard aims for
- Stream uncompressed audio and video up to Quad Full HD (QFHD) resolution,
- 48 bit color and 240 Hz refresh rates
- Support for 3D video formats
- Efficient data networking using IP
- Flexible wireless connectivity using USB bridging
- Simple, fast file transfer with OBEX.
- Low rate PHY (2.5-40 Mb/s) for omni-directional control and discovery
- Medium-rate PHY (0.5-2 Gb/s) for low power, mobile applications and lowcomplexityuniversal bi-directional data support
- High-rate PHY (1-7 Gb/s) for high quality, full resolution video
- Improved coverage and higher data rates (in excess of 28 Gb/s) through the use of
- the spatial multiplexing high rate PHY (SM-HRP) option
- Video coding to improve link robustness
- HDCP 2.0 in addition to DTCP content protection support
SAI has completed significant work in video streaming on existing protocols – WiMax, LTE as well as 802.11 in their various forms (802.16e, 802.16d, 3G,LTE Rel 9 as well as 802.11g/n/ac). SAI is extending such video streaming work into the Wireless High Definition technologies and markets for high performance full resolution video.
