Niagara SCX and SimulStream View tab Use the View tab (Figure 99) to preview videos as you encode. To watch the incoming video or see the output video standards, you must have installed Osprey SimulStream for the capture. Osprey SimulStream lets a single card produce multiple outputs. For more information or to purchase SimulStream for your Osprey video capture card, visit http://viewcast.com/products/software/simulstream. Figure 99. View tab The View tab has the following controls.
Niagara SCX User Guide Niagara SCX and SimulStream Niagara SCX and SimulStream represent the perfect team of tools for maximizing resources for encoding purposes. With just one capture card, you can encode a single source into multiple outputs. Examples include using a single video that you can encode in Adaptive, Flash, MPEG-4, and Windows Media. You can encode these simultaneously by using SimulStream.
Niagara SCX and SimulStream WARNING! If you enable or disable SimulStream after you save an encoder profile, you could disable the profile you saved. For instance, if you save a profile using Capture Device 1, then enable SimulStream, Niagara SCX no longer recognizes Capture Device 1 but sees Capture Device(s) 1.n instead. You see a red X designating a non-recognized capture device by that profile and must reselect your input device to Capture Device 1.n to clear the red X and use the profile.
Niagara SCX User Guide Enable checkbox The checkbox at the top of the group (Figure 100) turns on SimulStream for the currently selected device. The following table indicates the conditions for SimulStream. Figure 100.
Niagara SCX and SimulStream Show N filters per device With the Show N filters per device control (Figure 101) you can set up the driver to expose 1 to 10 filters per device for applications to specify and select. If, for example, you choose four filters per device, device lists in applications show four entries for the current device. For device 1, the system designates them as 1.1, 1.2, 1.3, and 1.4. Figure 101.
Niagara SCX User Guide Allow Multiple Instances of Each Filter This control enables you to run multiple application instances on one device that does not have device select controls. ViewCast recommends that you do not allow multiple instances of each filter unless you have a specific need for it. Turning it on affects some of the above description.
Niagara SCX User Guide Deinterlace This option removes artifacts that the system can introduce when encoding NTSC, PAL, or SECAM formatted video. These artifacts usually manifest as a jaggedness surrounding a moving object. You apply and store these filters per each device. Applies to all filters and pins associated with a specific device.
Deinterlace Motion adaptive deinterlace Motion adaptive deinterlace is the reverse of telecine. It is an algorithm for deinterlacing pure video (non-telecine) content. It detects the portions of the image that remain still and the portions that remain in motion then applies different processing to each. Motion adaptive deinterlace allows you to set the Motion Threshold and Smooth Motion or Sharp Motion.
Niagara SCX User Guide Tuning Utilities Some electrical signals convey television pictures. Cables then carry this video signal from one place to another. Along the way, the signal may pass through various pieces of equipment such as video tape machines, switchers, character generators, special effects generators, and transmitters. Any of this equipment can change or distort the signal in undesirable ways.
Tuning Utilities Understand the display The vectorscope display has two parts: the graticule and the trace. Graticule - A scale you use to quantify the parameters of the signal under examination. Graticule works with a color bar signal. Note: Remember, the color bar’s signal consists of brightness information (luminance) and high frequency color information (chrominance or chroma). Trace - The video signal itself. The demodulated chrominance signals electronically generate it.
Niagara SCX User Guide Waveform monitor Vectorscopes and waveform monitors (Figure 105) complement one another and provide a full representation of all information about the video signal. Figure 105. Waveform Monitor Display The nominal video signal level for television studios and production facilities equates to one volt (1 V) peak-to-peak. Note: The term peak-to-peak means from the bottom of the signal to the top. You often see it abbreviated as p-p.
Tuning Utilities Understanding the display The waveform consists primarily of a brightness signal (called luminance) and a high-frequency color signal (called chrominance). The luminance and chrominance added together form the overall waveform. The luminance signal, a series of voltages or levels, determines brightness and variations across the picture.
Niagara SCX User Guide Gamma Correction Gamma refers to the response curve of video cameras/CRTs. When you capture video with a camera, the camera response remains deliberately nonlinear – it boosts low lumen values and compresses high lumen values – based on two reasons: It increases the effective bandwidth in low lumen ranges, where you need it, at the expense of high lumen ranges, where you need it less. It matches the response characteristics of TV sets and monitors.
Gamma Correction Note: These values represent the inverses of the gamma bias that you applied at the video source per the video standard so the resulting video becomes gammaneutral.
Niagara SCX User Guide Appendix A: An Introduction to Streaming Media A live video stream refers to sending online video and audio signals real time to any number of viewers. No matter what the live content is – sporting events, local interest stories, governmentmandated open meetings, specialized business opportunities, or training sessions – there is a local or global audience for it.
Appendix A: An Introduction to Streaming Media Main workflow processes Media files can be quite large. For example, five minutes of uncompressed video requires almost one Gigabyte of space. To prepare audio and video for streaming, the media needs to be compressed to make the file size smaller. When a viewer requests the file, the video server sends a compressed file in a steady stream.
Niagara SCX User Guide What video streaming can do for you Broadband Internet makes possible a massive new audience that broadcasters, news services and other multimedia content providers can reach. The audience is already poised to receive voice, data and video content on their cell phones, PDAs, and notebook computers. Mass media via the Internet is a new source of advertising revenue. ViewCast empowers you to stream your content successfully to the perfect audience.
Appendix A: An Introduction to Streaming Media Figure 107.
Niagara SCX User Guide Video compression TV-quality video contains a huge amount of brightness information, color information and picture detail… much too much to cram down a small IP pipe like the Internet. Therefore, it needs to be converted to a form suitable for Internet or private network delivery. The technical terms for this conversion are scaling and compression, which together reduce the amount of network resources needed to convey a reasonable facsimile of the original picture and sound.
Appendix A: An Introduction to Streaming Media you “hire” a CDN to deliver your content. Some CDN companies have online account signup so you can create an instant relationship and be streaming globally in mere minutes. How viewers find the stream So far, you are capturing and encoding live video and audio and creating a TCP/IP stream. You have signed up a CDN, and now you want your audience to view it.
Niagara SCX User Guide Simple guide to streaming audio and video types As noted above, the encoder can create several different types of audio and video streams. Although all are a type of IP video format, each has certain properties that make it more attuned to a specific streaming video application. The following chart lists all formats available on ViewCast Niagara encoders. All of these formats can be used for many different applications.
