Introduction This guide is a non-technical introduction to operating The SP-14 for up/down/cross standards conversion with MEMC motion compensation. The guide describes how to setup, scale, adjust for the best pictures. This guide does not replace the product user manual and covers only the essential functions to get started. For further information refer to the user manual.
The Basic Setup The flowchart below represents the basic setup, additional information can be found further in this guide.
Flexible Connectivity The SP-14 can be used as a routing switcher and universal interface for connecting many up-to-date and legacy formats Inputs 2x 3G-SDI with automatic cable EQ, (HD-SDI & SD-SDI compatible) with embedded audio capability for 3G, HD & SD 1x HDMI with audio & deep colour, HDCP compatible 1x DVI-D, HDCP compatible 1x VGA Analogue graphics via 5 BNCs, supports RGBHV & RGsB 2x Composite Video via BNC (NTSC/PAL/SECAM) 1x S-Video via 2x BNC (NTSC/PAL/SECAM) 1x Component video YPbPr via BNCs 4x
Control via Front Panel LCD and Menu Buttons The SP-14 has front panel LCD display which gives status information and access to the in-built menu system. Kramer Electronics Ltd. SP-14 Software Ver: Safe Operation SP-14 features safe operating conditions 1) The front panel Standby button must be pressed and held for 4 seconds to activate 2) The front panel channel select and menu buttons are locked by default; to activate the front panel press the menu button and then the input button IN: 1920x1080i @50.
Setting Scaler Functions Default Settings The SP-14 comes with default setting that should give good results on most content but you do need to decide on some parameters for your application. As you get used to the unit you can be more adventurous Input resolution and frame rate The input resolution and frame rate is recognised automatically and displayed on top line of the status menu screen IN: 1920x1080i @50.00 Hz 3G-SDI 1 OUT:1920x1080i @59.
Set Lock Mode In this same section of menu set the reference mode for the output of the SP-14. Using the up and down arrow keys move Output Settings to the top of the window and press select [Output Settings Audio Closed Captioning Information ]↑ Press select, use the left and right arrow keys to choose the Lock Mode, press select [Lock Mode Reference Source Reference Offset Output Format Auto Format] Off 1080i50 ↓ Free Run mode uses the SP-14’s in-built clocks to provide sync timing.
Set ARC Mode If you are converting the Aspect Ratio of the picture there are pre-set modes to choose from or a custom mode, if you choose Custom Mode then you will also need to set the ARC Custom on the next line of the menu Using the up and down arrow keys move Output Settings to the top of the window and press select [Output Settings Audio Closed Captioning Information ]↑ Using the up and down arrow keys move Arc Mode to the top of the window and press select [Arc Mode Side Panels/Ltrbox 25%]↑ Arc Cus
Set MEMC Mode Background Motion Estimation Motion Compensated (MEMC) Frame Rate Conversion (FRC) creates temporally correct motion in a sequence of pictures when the number of pictures per second is changed. Basic Linear Frame Rate Converters either duplicate frames to increase the frame count or drop frames to reduce the frame count. A variation to this idea is to use an ‘aperture’ setting which causes the stepping of either dropped or duplicated frames to be blurred.
Linear FRC can result in the appearance shown in the second picture where the moving parts of the picture result in adjacent frames being merged together causing the appearance of blurring Picture 2 Linear FRC conversion results in the moving parts of the image being blurred The MEMC/FRC modes are pre-set to give good results on most content however, as with all motion compensation algorithms there are occasions when the video material characteristics require different settings.
FRC Level sets the amount of motion compensation difficulty tolerated before a frame is linearly converted. You may need to lower this level if your content is causing a disrupted picture. You can also turn off motion compensation if required. MEMC Low concentrates on the background, so ensures that global motion, large area pans of the image, are handled correctly even if this means dropping back to linear conversion for smaller objects on the image.
Adjustment of MEMC Cadence and Mask Cadence Detection [MEMC/FRC Settings Time Code Settings Input Select Input Adjust ] 3G-SDI 1 N/A ↓ Press select, to enter the MEMC/FRC menu Using the up and down arrow keys move Preserve Cadence to the top of the window and press select [Preserve Cadence Cadence Detect 23-30Hz Cadence Detect 50-60Hz Advanced On]↑ Non Accepted 3:2, 2:2 only .
MEMC Mask (exclusion area) [MEMC/FRC Settings Time Code Settings Input Select Input Adjust ] 3G-SDI 1 N/A ↓ Press select, to enter the MEMC/FRC menu Using the up and down arrow keys move MEMC Exclusion Zone to the top of the window [MEMC Exclusion Zone MEMC Demo Mode Preserve Cadence Cadence Detect 23-30Hz ]↑ Full Screen On Non Accepted ↓ Press select [Enable MEMC Mask Display Border Left Edge Right Edge Off ] Off 355 365 ↓ An area can be set to be excluded from the motion compensation process as it
Input Settings SP-14 has many features to help improve and re-master older material. The default settings assume that your material is good quality. If your material is noisy or untidy at the edges or lacks definition SP-14 can be used to improve the material in real time and at the same time as it standards converts. The following are suggestions for correcting or improving content.
Input Capture allows you to over-scan the image and then move around inside the area, This is particularly useful when dealing with film transfers where the gate was visible or for video from the M2 format where YC timing errors caused cogging on the leading edge of lines. The forth item is Input Features [Sharpness Detail Unsharp Mask 100] 0 0 Enables Sharpness and Detail settings to be adjusted to suit your material.
