A Word of Thanks Congratulations on choosing an openGear LDP-8242 Multi-Definition Loudness Processor. Your LDP-8242 is part of a full line of Digital Products within the openGear Terminal Equipment family of products, backed by Ross Video’s experience in engineering and design expertise since 1974.
Overview The LDP-8242 is ideal for correcting irritating loudness differences between programs and commercials. Featuring 24-bit audio processing that supports 16 channels of embedded audio from an HD/SD-SDI signal. With Linear Acoustic AEROMAX™ technology, the card applies loudness control on up to six channels of audio from any of the 16 channels of embedded audio.
Note: The input/output complement listed above and shown in Figure 1.1 and Figure 1.3 represent the maximum capability of the LDP-8242. Video and Audio Options In addition to the I/O options described in Table 1.1, the LDP-8242 offers the video and audio options described in Table 1.2. Table 1.2 Video/Audio Options...
Supported Audio and Video Formats Table 1.4 provides details regarding the audio and video formats supported by the LDP-8242. Table 1.4 Supported Audio and Video Formats Item Description/Specification Raster Structure: Frame Rate: 25; 29.97 1080i Input / Output 720p 50; 59.94 Video 29.97...
As such, functions described in this manual may pertain specifically to cards loaded with a particular software build. If you received your LDP-8242 card and this manual at the same time, this manual reflects all facets of your card.
“Video and Audio Options” on page 1-3, and as applicable throughout this manual. This section provides a functional block diagram that outlines the workflow of the LDP-8242. Note that signal connections shown depicts full input/output capability. Practical input/output signal availability is determined by the licensed features installed.
Descriptions below include some functions and features that are available only as options. The LDP-8242 features a frame sync that can select from either of two card frame reference sources, or free-run input video sync. In the event of input video loss of signal, the output can be set to disable video, go to black, go to an internal test signal generator pattern, or freeze to the last intact frame (last frame having valid SAV and EAV codes).
This function provides support for closed captioning setup. When enabled, the function allows passage of timecode data. The function also allows the selection of the ancillary data line number where the ancillary closed caption data is outputted when the output is HD. 1–8 • Introduction LDP-8242 User Manual (Iss. 03)
Descriptions below include some functions and features that are available only as options. Audio Processing Overview The LDP-8242 audio processing subsection is built around a card internal 16-channel bus. This 16-channel bus receives inputs from an input routing crosspoint that routes de-embedded and discrete AES signals over the 16-channel bus.
The resulting stereo pairs thru Downmix-A(L/R) Downmix-D(L/R) can in turn be routed and processed just like any of the other audio sources described earlier. See Figure 1.4 for an example. 1–10 • Introduction LDP-8242 User Manual (Iss. 03)
The internal bus receives its audio inputs from the input routing function and accommodates a maximum of 16 concurrent channels. This conduit serves as a centralized point for managing audio delay offset from video and master gain controls for outputs from the input routing function. LDP-8242 User Manual (Iss. 03) Introduction • 1–11...
A bulk (master) video/audio delay function allows adding or reducing audio delay from the video delay. The LDP-8242 re-establishes video/audio sync following framesync changes by applying an offset in small, progressive amounts to provide a seamless, glitch-free retiming. In addition to the master sync/delay controls, each bus channel has its own independent delay and gain control.
The example in Figure 1.8 shows routing of embedded output channels Emb Out Ch 1 thru Ch 6 fed through the loudness processor. A master output gain control is provided which allows fine adjustment of the overall output level. LDP-8242 User Manual (Iss. 03) Introduction • 1–13...
Figure 1.8 5.1-Channel Loudness Processor with Example Sources Tone Generators The LDP-8242 contains eight built-in tone generators (Tone Generator 1 thru Tone Generator 8). Each of the eight tone generators can be routed to the upmixer or directly to card audio outputs.
This section briefly summarizes the communication types available for the LDP-8242. Rear Modules The LDP-8242 physically interfaces to system video and audio connections using the R2-8242 Rear Module. All inputs and outputs shown in the video and audio block diagrams (Figure 1.1 and Figure 1.3 respectively) enter and exit the card via the card-edge backplane connector.
Figure 1.9 User Control Interface DashBoard™ User Interface Using DashBoard™, the LDP-8242 and other cards installed in the DFR-8321 series frame can be controlled from a computer and monitor. DashBoard™ allows users to view all frames on a network with control and monitoring for all populated slots inside a frame.
