This processing includes image sizing, positioning, rotation, warps, light sourcing, textures, and drop shadows. One of the unique features of the 8150 DVE option is its flexible channel configuration. The board comes with two channels: one main channel dedicated for video, and a second channel that can be used for video, key, or shadow.
  • Page 119 Signal Chassis 8150 Technical Guide The video for each channel is read out of the transform framestores, with addresses generated by that channel’s transform controller, and sent to the output interpolators. The transformed video and generated key information from each channel passes to the combiner, which composites the two channels together.

    8150 Technical Guide Signal Chassis Video-Key/Shadow Mode The Video-Key/Shadow mode is similar to the Video/Key mode, except that the key signal input to the B channel is processed by the A channel’s transform controller, so that the video and key are transformed identically.

  • Page 213: Effects Loop Processing

    8150 Technical Guide Effects Loop Processing Effects Loop Processing Conceptual Background Information While keying, it is often desirable to manipulate the processed key and fill signals in a DVE or other device before combining them with the background. Traditionally, this involved performing the key on one keyer, sending the processed key and fill out two Aux outputs to the DVE, manipulating the processed key and fill, and re-entering them to the switcher.
  • Page 214 Effects Loop Processing 8150 Technical Guide There are two types of 8150 Effects Loops. The first sends the processed key and fill of Keyer 1, Keyer 2, or the DSK to the DVE, and returns it to the same keyer. The second type lets you perform an M/E Background A/Background B transition (mix, wipe, or NAM), composite Keyer 1 over this mix, and send the entire composite out to the DVE for manipulation.

  • Page 215: Effects Loop Re-Entry Timing

    8150 Technical Guide Effects Loop Processing NOTE: Since the M/E processor and the PGM/PST/DSK processor share the Effects Loop return path, you can enable only one Effects Loop at a time. However, if you have four Aux outputs installed, you can use them to feed two different DVEs to create different Effects Loops, as long as they are not used simultaneously.
  • Page 216 Effects Loop Processing 8150 Technical Guide The Engineering menu Input submenu Effects Loop Inputs softkey has two pushknobs that select DVE video and key inputs. Note that there are independent settings for DVE 1 and DVE 2, to support two pairs of Aux outputs as described above.
  • Page 217 8150 Technical Guide Effects Loop Processing DVE Effects Loop Inputs must be the video and key outputs of the video combiner, and the other pair of DVE Effects Loop Inputs must remain set to 0. In any Effects Loop mode, the DVE video and key re-entries are not correctly timed for use as direct sources in the 8150.
  • Page 218 Effects Loop Processing 8150 Technical Guide NOTE: Because the input timing window for an entire Input module is changed, the DVE video and key inputs must be connected to the same Input module for effects looping to work properly. STEP 5: This completes the connection and setup for a single external DVE (for two external DVEs, see step 12).

  • Page 220: Encoding The 8150 Output (Ntsc)

    The 8150 processes only component video, so does not provide composite outputs. If you are operating in the 525-line standard and need a composite output, you can use the Accom A28 Digital Encoder to output composite digital and analog video for monitoring, recording, etc.
  • Page 221 Make sure you have the A28 Timing Modification Upgrade STEP 1: Kit (Accom P/N 9300-00-7900) before you begin. This modification lets you delay the A28 output sync and burst to match the delay of the 8150. The modification kit consists of a programmed IC and some rework wire.
  • Page 222 Encoding the 8150 Output (NTSC) 8150 Technical Guide STEP 9: Set DIP switch U15Q position 1 to ON. This delays the A28 output sync and burst to match the 8150 delay; turn the switch OFF if you are feeding a source other than the 8150 to the A28. STEP 10: Reinstall the Main board and option module(s) into the bottom chassis tray and reinstall the tray into the upper chassis housing.
  • Page 223 8150 Technical Guide Encoding the 8150 Output (NTSC) O/P KA and O/P KB (Options G and H only): These are identical composite analog key outputs if Option G is installed, or identical serial composite digital key outputs if Option H is installed. Only use these if you are feeding a key signal to the A28 that matches the timing of the 8150 program or preview output.
  • Page 224 Encoding the 8150 Output (NTSC) 8150 Technical Guide I/P KA and I/P KB: Use these inputs only if you are feeding serial component digital key signals to the A28 that are cotimed to the 8150 program or preview output. Note that the A28 encodes only one input key signal at a time.

  • Page 225: System Timing

    8150 Technical Guide General Timing Considerations Section 6 System Timing General Timing Considerations Introduction Using digital processing in a post production switcher lets you implement features that would be difficult, or at least very expensive, with a traditional analog switcher. Because the video is processed digitally, you can use features such as automatic input timing, key and border defocus, wide keyer borders, vertical key sizing and positioning, and high resolution 4:4:4 chroma key extraction and downsampling.

  • Page 226: System Locking Reference

    Video encoders often require a black burst reference to add correct sync, burst, and blanking to the final composite output. The 8150 does not output a black burst signal, but in 525-line environments, the Accom A28 Digital Encoder has a mode that can properly encode the 8150’s output for a composite digital (D2) or analog (NTSC) signal.

  • Page 227: Aux Output Sources Delayed By Two Lines

    8150 Technical Guide General Timing Considerations Aux Output Sources Delayed by Two Lines Any external input is immediately delayed by approximately two lines from its original timing due to the automatic input timing circuitry (-1/2 to + 2 lines from reference). This means that if an external input to the 8150 is routed directly out an Aux output, it is delayed two lines from 8150 reference, no matter what the original timing of the source.

    4. The example in Figure 6-1 shows a standard Aux bus feed out to an Accom A57, which returns to an 8150 input as a re-entry to the M/E. In this example, the Aux bus and the Aux Ref are delayed two lines with respect to reference.
  • Page 230 General Timing Considerations 8150 Technical Guide If Aux bus outputs 1 and 2 are installed in your 8150, they have one of the three delay values described above, and they are always zero timed to each other. Similarly, if Aux bus outputs 3 and 4 are installed, they have one of the three delays, and are always zero timed to each other, but not necessarily to Aux 1 and 2.
