How do you desensitize a jitter in an application?

Answer 1

Buffering, on the receiving end, desensitizes transmission jitter for the receiver. Once data is received, the more random (not uniform) the transmission, the more buffer space is required. Each process on the 7-step OSI (Open Systems Interconnect) model layer takes processing power & time for each nugget of data passing up from the physical layer to the application layer. If there is not enough buffer for each part of the process, before it is dealt with and passed up to the next layer, bits may get dropped, and not all data makes it to the application layer. Note that encryption, deployed today, plays a very negative role here (but does play a very important role). If all data has to basically bypass the mid transportation layer and has to be taken care in software (e.g. to un-encrypt), the advantages of hardware performance are avoided. Also, any dropped packets/information has to be replaced if needed. The OSI transportation layer does this fairly efficiently with TCP (Transmission Control Protocol), relative to how well the application layer will. Some types of data do not require that all bits get to the destination but enough needs to get there for the use of the information to be understood. How much information needs to get to the destination is determined by the application and user acceptance. Most data is considered corrupt if one bit is missing but there is enough redundancy in audio & video that some bits can go missing. When bits are missing from an audio or video stream, the result may be un-noticed, un-comfortable, or un-recognizable depending on the amount not received and presented to the user. Audio and/or video streaming can be buffered to counter act the effects of transmission jitter. Applications that need real-time response (2-way communication) will have some delay, to the end user, due to buffering requirements. This is just the simple version of the jitter issue. There is an incredible amount of impressive research that has been done and is still being done to further enhance the effects of jitter.
