Rendering Figure 1 1 Video Preferences Showing NVIDIA SDI Configuration CHAPTER 1 RVSDI rsd Video device latency ls the sum of the latency computed by the video device the known latency an external flxed latency In seconds and an additional external latency In frames relative to the current video format frame rate The total latency can be used to offset audio output Device Latency 208 333 ms Fixed Latency o seconds Frame Latency 6 5 frames Total Latency 479 167 ms x Cancel Figure 1 2 Latency Configuration Panel With a Manually Added External Frame Latency CHAPTER 1 RVSDI Output Audio to this Device If checked audio will be packaged as ancillary data in the SDI frames Otherwise audio will be output through the selected audio device on the computer RVSDI currently will output audio data on the first four audio channels Only a left and right channel is supported and each is duplicated Incorporate Video Latency into Audio Offset If checked the total latency as indicated in the Con figure Latency dialog box will be applied to the audio offset but only if audio is being played by the controller instead of the output device i e Output Audio to this Device is not checked This is especially useful with NVIDIA SDI output because the device has up to five frames of latency The buffer size can vary over time so RVSDI can measure and automatically add latency to the computer s audio output
3. computer s audio output if you don t have an SDI audio device We recommend the latest certified SDI NVIDIA driver You can find this on NVIDIA s website for your operating system and specific Quadro card Make sure you search for the Quadro SDI driver not the generic Quadro driver 1 2 1 Using the NVIDIA Driver The SDI video device should be turned off in the NVIDIA driver configuration On Linux this is done in the nvidia settings program On Windows use the NVIDIA control panel In other words do not use the SDI devices as an extension to the desktop When used in that manner RVSDI cannot access the device itself RVSDI will start up the SDI device during presentation mode and turn it off when presentation mode is off or RVSDI is not running 1 3 Getting Started You should have received a license file containing both an RVSDI license and an RV license Both licenses can be floating if desired The rvsdi executable or rvsdi exe on windows differs from the regular rv binary in that it can interact with the NVIDIA SDI hardware On Windows navigate to the RV installation s bin folder and launch the rvsdi exe binary On Linux go the bin directory of the RV installation tree and start the rvsdi program CHAPTER 1 RVSDI Once the RVSDI executable has started the first thing you should do is open the video preferences tab under RV Preferences Video This is the primary interface to configure the SDI device for presentation
4. to aid in keeping audio synced with video When outputing the audio in the SDI packets directly Output Audio to this Device then this is not an issue If you have additional SDI devices that also buffer frames connected to the output you may have incorporate that into the total latency in the Configure Latency dialog box Controller Display Mode When presentation mode is active the session window can behave in one of two ways It will either mirror the output going to the presentation device literally or it can have its own seperate display The default is for the session to have its own display which is scaled independently of the presentation display When using the NVIDIA SDI video devices there s no good reason to the mirror mode 1 5 Issues with Stereo The SDI device has a single additional stereo mode beyond stereo emulation that rv already has stereo dual output This data format outputs the left and right eyes each on its own SDI output When using SDI stereo you do not need to set any of the stereo modes under the View Stereo menu you should leave this off for most situations The View Stereo Hardware mode is not only unecessary but can be confusing in this situation That mode is for use only by the controller window it has no effect on the SDI output This mode enables Quad Buffered Stereo which is only available with Quadro cards connected to 120 Hz or faster DVI or DisplayPort monitors The other stereo emulati

6. on modes anaglyph etc will function with SDI when not using the dual output format When the dual stereo output format is selected the stereo emulation modes will output images for each eye So for example anaglyph will output a red left eye image and cyan right eye image for each SDI output Right and left eye only modes will duplicate the eye on each output 1 6 Command Line Invocation You can start RVSDI like this to fully specify To use the presentDevice option you could do e g rvsdi presentDevice NVIDIA SDI O for the first SDI device These can also be set using the prefs by selecting the Use as Presentation Device check box The presentVideoFormat and presentDataFormat will search for a video or data format that contains the passed in string So for SDI you could do rvsdi presentVideoFormat 1080p 24Hz presentDataFormat Dual which would find 1080p 24Hz SMPTE274 as the video format and Dual 8 Bit YCrCb 4 2 2 as the data format Some other examples rvsdi presentVideoFormat 720p presentDataFormat 4 4 4 would be 8 bit 720p 59 94Hz because that is the first 720p format The first matching data format to 4 4 4 is 8 bit YCrCb 4 4 4 You can be more specific like CHAPTER 1 RVSDI rvsdi presentVideoFormat 720p 60Hz presentDataFormat 10 Bit YCrCb 4 4 4 RV will pick the first video or data format that contains the passed in string These strings are device dependent Ideall
