Streaming communication is one way with the exception of VoIP but requires an external computer with VolP software Streaming Pros Allows digital audio quality 20Hz a 15KHz Allows stereo transmissions Interferences free Contras Latency The signal arrives delayed due to the Internet latency This delay depends on the connection type and characteristics of the Internet service in the area It can be from 0 3 to 5 seconds Unidirecional from console to Studio except that case of VoIP but requires an external computer Telephone Pros Without delays Full duplex Contras The audio quality is restricted by telephonic band 300 to 3 400 Hz it can be improved with VQRG system but not reach the audio quality of streaming transmission SOLIDYNE CODEC MIXER MX2400 Not support stereo transmission High cost for long distances Using cell phones distortion increases and they are susceptible to interferences At the studios the operator always will prefer to send on air the streaming audio except in the following cases a If there are problems receiving the streaming eg by overloading of Internet provider s network b When the delay becomes difficult a fluid conversation between Studios and the location The first case rarely happens but if streaming reception fails audio drops or glitches the on air operator switches to the telephone signal to continue the

12. the return from Studios Just in case that a dialogue between the Location SOLIDYNE CODEC MIXER MX2400 and Studios the operator of MX2400 will use the return from studios If the latency is small less than 0 5 seconds does not affect the dialogue being on air the audio streaming while the MX2400 receives return via cell phone If the delay of the streaming make difficult the conversation the operator at the studios leaves the streaming and put on air the cell phone Remember that the phone audio can be improved using the Solidyne amp VQR technology 5 2 1 How to talk in private with the MX2400 s journalist Some time ago when the link were made by land line phone just a phone in parallel with the line was needed to speak with the remote operator But using mobile phones connected via Bluetooth you must consider the talk back circuits of hybrids and consoles In the Solidyne broadcast consoles this issue is solved since the hybrid signal is received directly into the console which has a microphone for talk back which the operator can talk with the MX2400 operator This is true even for an external hybrid connected to the console Some hybrids include a microphone and a headphone output to private speak with the caller when the line is off air In consoles that do not have a talk back communication circuit you must use a microphone connected to a channel Obviously this channel is sent to the hybrid but not
13. transmission from location The second case is a dialogue between Location and Studios If due to the features of the Internet service are not achieved low delays in the streaming transmission the delay can difficult the conversation because the interviewed at the remote location listens the question from Studios by phone in real time but its response reaches the Studios delayed via Internet The results on air are pauses of silence between the question from the Studio speaker and the answer from the remote location In this case put on air the audio from the hybrid with no delay instead of streaming Remember The codec mixer MX2400 allows both digital stream BS and audio by cell phone so that the Studios make the decision of which option will be sent to air For example using the streaming for sports and switching to phone link with lower quality but without delay for the interviews at the end of the match 5 1 2 streaming path As seen 3 2 Transmission over Internet there are two ways to operate Internet communications whether from a broadband Ethernet connection or a GSM cellular data network In either case you can work A Using a streaming server recommended for its operational simplicity Requires a monthly subscription which is very low cost B Direct link from MX2400 to Studios Least cost method due not requiring a Page 25 subscription to a streaming server But requires more knowledge of co
