The IP Link MPXp codecs support AES192 digital signal transport, which minimizes analog-to-digital conversions and positions all audio processing and limiting functions at the studio. Ray Smith, Transmission Manager for MediaWorks New Zealand, correlates the audio quality improvements with the flexibility of MPX over IP transport. The synchronous performance across the SFN has been outstanding, and Mediaworks reports excellent audio quality and stability from the next-generation Flexiva exciters.” “This eliminates signal drops and vulnerability issues of the legacy architecture, which required Mediaworks to route the Auckland program to Hamilton for local ad insertion. “The migration from older E1 linking technology to IP, while partially prompted by the recent availability of the latter, also enabled simplification of the routing for the Auckland transmitter as it now comes directly from the Auckland studio,” said Simpson. The modernized design eliminates the need to transport program audio to a separate studio for local ad insertions. The complete solution leverages Intraplex IP Link MPXp codecs with built-in SynchroCast technology to transport FM baseband and manage local ad insertions across its single-frequency transmission network (SFN), with Flexiva FAX50 exciters to support FM radio signal generation at each transmission site. Mark Simpson, Account Manager, Transmission and Distribution Systems at Gencom Technology, confirms that migration from a more complex legacy TDM networking infrastructure was the “prime catalyst” for the upgrade. GatesAir’s regional channel partner Gencom Technology provided all presales design support, working with GatesAir product specialists and MediaWorks engineers to develop the now-live IP-based configuration. Specifically upgrading the transport infrastructure of MediaWorks Radio’s iconic commercial brand, The Sound, the project refines and enhances the delivery of program audio from its studio in Ponsonby, Auckland, to synchronous transmitters on 93.8MHz FM at Auckland’s Sky Tower and Mount Ruru in the Waikato region. The new transport solution keeps all signals in the digital domain and streamlines signal delivery, at once improving audio quality, reducing system complexity, and lowering the costs of live distribution linking across a single-frequency FM radio network (SFN). A full list of available transitions types is here.Transition to Intraplex IP Link MPXp codecs and next-generation Flexiva exciters simplify local ad insertions, improve audio quality and reduce networking costs across single-frequency networkĬINCINNATI, SeptemGatesAir, a global leader in wireless, over-the-air content delivery solutions for TV and radio broadcasters, has transitioned longtime customer MediaWorks, a New Zealand-based television, radio and interactive media company, to an uncompressed Audio over IP networking architecture. You can use any transition type that is supported in MFormats SDK. 0.1 - in this case transition takes only 10 frames). To make transition slower you should set step for transitionPos smaller (for example, 0.01 - in this case a complete transition from 1st source to 2nd one takes 100 frames), and to make it faster you should increase the step (e.g. So you can vary a speed of transition by changing transition position parameter. if it is 1.0 - the frameResult is equal to frameTo.if it is 0.0 the frameResult is equal to frameFrom,.The effect depends on a transition position ( transitionPos): You can use a frameResult object for preview or to output, or whatever you like :) MySecondSource.SourceFrameGet(-1, out frameTo, "") įrameTo.MFTransition(frameFrom, out frameResult, transitionPos, transitionType, "", "") MyFirstSource.SourceFrameGet(-1, out frameFrom, "") In common case transition between frames looks like: // get a frame from 1st source You can receive them from sources or create new ones. To make a transition you need 2 MFFrame objects. This property is reserved for future usage. ![]() ![]() _ bsPropsList - additional properties._ pFrameFrom - a frame from which the transition is used.You can control the position of a transition and its type. This method mixes 2 source frames according to given parameters and returns you a mixed frame. You can do it with the MFTransition method. For smooth switching between sources, you can use transitions between frames.
