to three Hz. It uses the MS-frame to provide 40ms algorithm latency.The G722.1 achieves lower bit rates and greater compression than the g.722 codec. The goal is to achieve roughly the same quality as the g.722 at approximately half the bit rate. This license to use the code requires the authorization of Polycom Corporation.5, G722.1 Annex CThe G722.1 Annex C is based on Polycom's siren 14 compression technology, which uses 32kHz sampling frequency t

2. g.722.1: low-complexity coding at 24 and 32 kbit/s for hands-free operation in systems with low frame loss
Encoding type: Transform the domain Audio CodingEncoding rate: 24 kbps and 32 Kbps (in fact, more bit rates can be achieved, with an increase of 8 kbps, and a higher bit rate version with 32 KHz sampling );
Theoretical latency: 40 ms (20 ms frame size + 20 ms lookhead)
Sound Quality: audio algorithms such as MP3 and WMA are better at low bit rates.

"One" how to generate a picture grid, I think of two ways:
(1) Cut this large picture into 16 pieces and then use the IMG-labeled SRC
(2) Only a large picture, and then each element of the background map with the CSS background-position to cut positioning, so you need 16 of the array [0,0],[-150,0],[-300,0] ... (I use this)

Preface
In terms of transmission rate, 802.11n can increase the WLAN transmission rate from 54 Mbps currently provided by 802.11a and 802.11g to 600 Mbps or even up to Mbps. The mimo ofdm technology, which is applied in combination with MIMO (multi-input and multi-output) and OFDM (Orthogonal Frequency Division Multiplexing) technology, improves the quality of wireless transmission and greatly improves the transmission rate.
The existing 802.11n Wireless AP/routing devices are mainly M and M pro
