I am trying to
-capture and synchronize video and audio
-compress the captured data
-transport the compressed data using suitable protocols
-decompress the received data at the other end
-and finally playing it over the LAN.
So, which protocols should I use: H.323 or RTSP or anything else?Which are the best suitable APIs for the above steps?
I'm trying to put together the best scenario for a large business to set up videoconferencing between users within the states and overseas. From my understanding, the company would have to set up a MCU to manage multiple audiovisual sessions. Then implement an SIP software such as Asterisk, with a registrar server to maintain a database with information about the network addresses of each user on the domain.The diagram in my head is something like this:

There is a Video Conferencing device setup in the branch office . We want to reserve 1MB bandwidth for the video conferencing and leave the remaining BW for Data .

I have only seen this problem with several video conferences from one location. Currently there is only one T1 connection from our HQ to remote location. When two conference calls are set to use 256Kbps connection to come back to the main HQ, after an hour or so the T1 connection would drop. What I mean about drop is that the route on the 2911 will disappear. I have to wait about 10 minutes for the connection to come back up or I have to reboot the router for the connection to appear again. There are no interface drops on the serial connections or ethernet connections.

I need to transfer live video and if possible video from station A to station B over wireless network. So what are the hardware requirements and setup cost...
Secondly how should i connect my CCTv cameras atleast 5 to computer's webcam so that i can transfer video over internet.
I recently bought 3 DCS-920 to monitor my home while at the office. However I can't seem to get the damned things to stream video using the dyndns service. I linked my router to the dyndns account and host service. I portforward the ports my cameras are assigned. Up to this point its all good, I can access the cameras and their settings pages while outside. However both the Java and ActiveX options for video streaming do not work. Even within the network, using their raw IPs to view the cameras the videos stream works.But putting in the hostname and port they are assigned brings up the camera page, but no video.I can only assume the ports the video and audio run on are seperate, as when I put one camera's IP in the DMZ host on my router, it works with the DNS. Unforunately I can only do that with 1, and I'd rather not do that at all.
View 6 Replies View Relatedlooking to pick a good managed gigabit switch for my central media server implementation.I will have probably 10-12 tvs connected to this along with other things like ip pbx extensions, music streamers, ip cameras etc.Now I can imagine about 2-3 tvs simultaneously streaming HD quality movies. In that case, I am assuming I will need a minimum 150-200mbps throughput switch. Is my assumption wrong?I have been looking at some switches which seem nice and relatively inexpensive but the throughput is much lower than that.If I wouldnt need that kind of throughput then can you explain me how do I come up with my max limit.I initially thought that since its going to be a gigabit switch it would be able to handle that kind of traffic through all its port at once, but I guess thats not a correct assumption. Throughput is what reall dictates simultaneous maximum? Am I correct?

View 1 Replies View RelatedI am currently wirelessly streaming BR rip movies from my PC tower to a PS3. I have a gigabit connection from the PC to the router (D-Link DIR-825) which is broadcasting (5Ghz 'N') to a D-Link DAP-1522 bridge. Gigabit connection from the bridge to the PS3. The router is reporting a 70-75% connection with 240mbps, although I am realistic and don't expect that. I had been ripping and compressing my BR movies to 4-8GB. I had never noticed any trouble with these because my network can easily handle the additional traffic if it had been doubling or tripling these. I recently purchased a 2TB HDD and decided to just rip and not compress a few of my favorites. So now instead of a 3-10Mbps stream I have 15-45Mbps streams. I am ripping them straight to an .m2ts container (AVC/AC3) when the original video codec is AVC and converting to .mp4 (AVC/AAC) with Ripbot if the original codec is VC-1. Neither container makes a difference.
What's happening is that when I stream these uncompressed BRs, the picture and audio stutter and jump (indicating a bit-starved network connection). When I check the bitrate reported by the PS3, it is showing 80-150Mbps. I have run these video files through Bitrate Viewer just to be sure, and they are all running at normal bitrates, i.e. <50Mbps. Somewhere along the line, my network is doubling or tripling the stream. I have used both Mezzmo and TVersity as my DLNA servers with the transcoding turned off. The files playback fine at the expected bitrates on the PC with VLC Media Player.
Also, the problem is not with the wireless bridge. I was linked with a Linksys WET610N, while working on this problem, I attempted to update the firmware and bricked it. If anyone needs a DOA WET610N, they can have it for the cost of shipping. The DAP-1522 is getting a better signal and reporting a higher bitrate ceiling than the Linksys was.Is there a PC or router setting that could be causing this? I have even done a reset to restore the factory defaults on my router, but it hasn't made a difference.
I have been having a problem with my 4400n dropping connection when streaming video / audio.It is connected half duplex to a cat2950 and the media server is mediatomb on a linux box the client is a ps3 presently.

Before the router change, I was able to playback video over the network with no problems. If I connect the Linksys WRV54G again, the issue goes away. The Linksys WRV54G does not have gigabit and I have read related issues of video stuttering over gigabit.

View 1 Replies View RelatedEvery year I attend a local motorsport event and I am usually responsible for providing a live online video broadcast of the event which I do using a website such as ustream.tv or similar. The event is non-profit so spending as little money as possible or none at all is the best option for us. We use a 3G card/dongle and a laptop with 2 or 3 webcams for the video feed....The results/scoring system in use at the event is controlled by the organisers and they have setup a VNC server where teams can connect with their laptops via a wireless network to view results, what I would like to do, is to include the results screen in my video feed. So somehow, I need to trick my computer into thinking that the VNC viewer software is a video input device.I have looked for something similar last year but didn't have much success, If separate laptops are needed, I have 3 windows laptops at my disposal and a macbook pro which will be on the same network. Whichever one will be most suitable for the task will be used.

Netflix works decent most of the time, buffering occasionally but Youtube buffers all the time and is not watchable. Using a Netgear WGT624 b/g router located some 60 feet away a half floor upstairs. Internet downstream speed is about 5.5 Mbps on the hard wired main computer and laptops show the same speed when connected wirelessly.
