VoIP codecs convert analog voice signals to their digital encoded version. Codecs vary in size, sound quality, bandwidth and computation requirements. The most common VoIP codecs currently available are: G.711 (alaw & ulaw), G.723, G.726, G.729, GSM, and iLBC.

The word "codec" comes from COder/DECoder. A codec defines the algorithm used to convert analog signal into digital signal and vice versa. Each algorithm consumes different amount of bandwidth and provides different voice quality level. In the VoIP world the codecs are used to encode the voice for transmission across an IP backbone. Another name for voip codecs is "vocoders".

The codec for each call are negotiated between the caller and called party at the time the call is being setup. Moving your preferred codec higher in your VoIP phones priority list may allow it to be selected over the other codec's.

Dial-up can be used for VoIP when necessary or if its the only type of connection available. However, we recommend using broadband since certain VoIP codecs (e.g. G.711) require higher bandwidth.

VoIP Service Providers can be selected based on the services and calling plans that they provide. The features they offer can greatly differ based on the price of the calling plan that you choose. Rates vary between providers and their pricing ranges from per minute charges to flat monthly bills. Choosing the right calling plan should be based on your monthly telephone usage and company budget. The list shows current available VoIP Service Providers

A codec is a downloadable software encoder or decoder for a particular media format that is geared towards a specific computer platform. Codecs function much like plugins for browsers, and are used by players or authoring software to work with the specific media type. Most codecs that you will come across are decoders that are geared to presenting media content to players.

Voice over Internet Protocol (VoIP) - technology that enables one to make and receive phone calls thru the Internet instead of using the traditional analog PSTN (Public Switched Telephone Network) lines.

Yes, you can connect the V12 to a PC or Mac that supports the Bluetooth Headset or Handsfree profile. To do this you need to have Bluetooth enabled in your computer by using a Bluetooth USB Dongle or having a computer that has Bluetooth inbuilt. Depending on the Bluetooth software installed, the connection process is different. Simply put the V12 into Pairing mode, then activate a search using your computers Bluetooth Software.

In order to transfer voice (analog signal) over IP (internet), the voice message must first be digitized. Codec basically transfers voice into data in order to travel through the public internet network. Presently codec algorithms are designed to reduce the size of their voice packets to increase speeds of transmissions and reduce bandwidth loads on the network.

Open an uncompressed audio file with QuickTime Pro. Go to the File menu and select Export... Export As should be set to either Sound to AIFF or Movie to QuickTime Movie. Press the Options... button. If you have chosen Sound to AIFF as your export type then skip to step 6. If you have chosen Movie to QuickTime Movie then you need to press Settings... in the Sound area. Set the Compressor to "QDesign Music Codec". Set the desired Rate, and Use. The Size must remain "16 bit". Press the Options..

Contact your camera manufacturer. Although Microsoft provides some guidance and input to camera makers on their RAW codecs, they ultimately decide which features get implemented. If you have run into an issue that you believe to be a bug, they may need information from you to help troubleshoot and resolve the issue, so it's best to contact them directly.

VoIP gateways are devices that take analog voice signals and convert them to IP for transport over the LAN or WAN.

There are a lot of codecs, and as many places to get them as there are codecs. If you downloaded a video from the web, and you don't have the codec it requires, check the website you downloaded the video from for information on where to get the codec.

VoIP stands for Voice over Internet Protocol. VoIP is the technology that makes SunRocket service work. VoIP enables the transmission of voice data over the Internet using a voice adapter. By utilizing the power of the Internet, rather than the antiquated traditional phone network, SunRocket can deliver more powerful features and greater cost savings.

The TX1 uses Motion-JPEG, which is essentially a series of JPEG compressed images taken in quick succession and strung together into a movie (for a more scientific overview of the codec, see this Wikipedia article) Many people believe this was an odd choice by Canon because it is not a commonly used codec for video cameras, and creates movies that are extremely large (in file size) when compared to more modern codecs like MPEG4

There is no one right codec and each is designed for a different purpose. The common codecs for web delivery are: in QuickTime, Sorenson and Cinepak; in Windows Media Player, MS MPEG4. Real uses its own codecs.

Yes, you can use the DivX codec with our products. You can either use the compression dialog of the control and select the codec from the list of available codecs, or use @ctiVideo together with AVIEncoder to gain programmatically access to the codec selection and properties. Please, send any questions, comments or suggestions about this site to webmaster@activevideotools.com

The HiView 1000XP will automatically select the correct Video/Audio Codec, but if you wish you can select the preferred version. From a quality aspect, H.264 represents the best Video quality and G.722 gives the best Audio quality.

POTS Codecs are most commonly used for live broadcast of news, interviews, traveling talk shows, sports, and entertainment audio. POTS Codecs often stand by as backups when ISDN or satellite is used for a primary feed. Some radio stations use a POTS Codec as a backup to their studio-to-transmitter link.

ISDN Codecs are most commonly used for remote broadcasts of traveling talk shows, traffic and weather services, and sportscasts. Today, many on-air personalities have ISDN connections at their home in order to broadcast from a home studio. Some radio stations use an ISDN Codec as a backup to their studio-to-transmitter link.

iVideoMail is using the most popular build in codecs on the Mac (H.264,MPG4,SORENSON3). There are maybe better ones but don't forget, it will be delivered by email, so it's best to keep the files as small as possible. Play around with the settings and let me know which config works best. ˆback

The G.711 codec has traditionally been used in telephony networking. The 64kbps rate is due to using an 8 bits sample size x 8000 Hz sampling rate. Speech encoded using G.711 is not compressed but uses much more bandwidth that other codec designed for packetised speech. G.711 a-law offers a slightly wider dynamic range but less sensitivity to small changes in speech compared to G.711 µ-law. Astratel support the G.711 a-law codec.

Suppose I have a 4-bit signal, continuously updated, which I want to feed to a DAC (4bit,16steps of output voltage) which drives a speaker. The audio DAC takes a 16-bit sample in serial at certain sampling frequency. You can map your 4-bit sample to a 16-bit sample to drive the audio DAC. You can certainly combine (sum) these output signals sample by sample (if they are output at the same frequency) and then map the result to a 16-bit sample to the on-board DAC.

None. Why? I can't find any that would compress as good as Winzip could and that are not lossy. The best lossy codec turns that 140 MB video to a little over 1 MB. The best lossless one I found still puts it to 3 times what you download (about 300 KB (Usually, lossless compression is much bigger than lossy, for me, it's the other way around.)). Plus, if a user doesn't have the right codecs on their system, they won't be able to view the video at all.

Yes if you get an internet connection just for VoIP. This is an option which only big companies would go for. In normal circumstances we get internet connection for surfing the net so we need a computer for that, though you can bypass the computer while making VoIP calls by using ATA or IP Phone.

bull; Sometimes when I am on a call there is a beeping noise which is so loud that I cannot hear the other party. This applies to Vigor 2100V, 2500V and 2700V models only. When you are on a call which is going thro...
