20170235544
The disclosure relates to a communication system configured for enabling chatting between garners, wherein each gamer is communicating with other garners by a respective control device.
For computer games where users are divided into multiple teams competing against each other, it is important to the individual user in each team to hear his teammates clearly with low latency. Therefore, the preferred solution for these kind of computer games is to connect the headsets and game exchange gear together through some sort of analogue or digital chat connection. Online chat solutions like Skype or other internet based chat solutions are not preferred because they have too much latency and can be unstable.
There is a need for a simple solution which can be set-up by individuals without training as well as being easy to control for each individual user.
Patent U.S. Pat. No. 8,602,892 B1 centralizes all audio from each gaming console and distributes it out to each individual user. This is a complex setup and does not allow each individual user any controls. The solution requires a technician as also described in the patent to control the sound distribution in the system.
Patent U.S. Pat. No. 8,571,695 B1 discloses a communication daisy chaining which is a relatively simple method to achieve game chat audio sharing. The system offers little control for each individual user, specifically there are no controls of the sound level of the microphone signal from each individual user that is sent over the daisy chain connection.
There is a need to provide a solution that addresses at least some of the above-mentioned problems.
