Explanation Question Answer Explanation Question Answer Explanation Question Answer Explanation Question Answer Explanation Question Answer Explanation Question Answer Explanation Question Answer You will need to check with the CDN Service Provider if their media server can accept a direct RTSP stream. If not, most Service Providers have desktop soft client that accepts USB WebCam and USB Audio. The Vaddio device can be place in USB Streaming mode for these instances How many Clients (media players) can connect to the Vaddio Device? Only one is recommended. The Vaddio devices were designed to support a push model to a Media Server for multiparty distribution. Video drop outs may occur with multiple clients connected to the Vaddio device due to CPU limitations on the embedded processor Can the Vaddio device stream IP and USB at the same time? No. The user will need to determine if USB mode or IP Streaming mode. This is due to limited CPU resource on the hardware platform to support simultaneous operations. Configuration Questions What is the Quality Setting in the Streaming Configuration Page mean? This is composite of encoder setting optimize by Vaddio engineering to produce high quality video. The H.264 encoder on the Vaddio devices are based on variable bit rate (VBR) scheme. The VBR scheme dynamically adjusts frame rate and encoding profiles based upon available network bandwidth. The Quality Setting of "High Quality, Standard, and Low Bandwidth" represent the optimum encoder profile for selected Video resolution Can the Audio and Video synchronization be adjusted Yes for the AV Bridge The AV Bridge includes an audio delay feature that allows buffer audio based upon user setting (in 30msec increments). This allows the installer manually synchronize the audio and video streams compensating for any video frame delay occurring upstream of the encoding Can the Web Pages be used for Remote-­‐Real Time PTZ Controls during streaming operation? Not Recommended The Media Players can introduce significant amounts of delay (up to 15 seconds in HLS mode) associated with buffering. The Web PTZ control pages are near instantaneous. For example a Pan Control issues on the Web Page may not be seen in the Media Player until 15-­‐seconds later Can the RTSP Port be assigned to any value? Not completely The Streaming configuration page has a editable text box allowing the installer to set desired port. The Vaddio device will support port 554 and anything above 1024 The USB Streaming has support for two Color Space formats, what does the IP Streaming support? 4:2:2 Only Vaddio - 131 Cheshire Lane - Suite 500 - Minnetonka - MN - 55305 - www.vaddio.com ph: (763) 971-­‐4400
