Avenue 7910 HD Upconverter and Cross Converter

The 7910 module accepts an SD or HD SDI input and has four HD SDI outputs. Excellent for on-air use, the 7910 is equally at home in an HD island, in a signal ingest installation, or in a production application. Since the 7910 functions as either an Upconverter or Cross Converter, it’s useful on the output of a server when material may switch between HD programming and SD commercials. It’s also convenient in a dual-rate master control environment.

Sophisticated Adaptive Noise Reduction ensures delivery of a pristine output that is excellent for use in broadcast. Additionally, Picture Detail Enhancement is used to recover information that has been lost due to poor frequency response upstream. Aspect ratio conversion choices include: Letterbox, Anamorphic, Crop and Manual Zoom.

Input standard and frame rate are auto-detected. The 7910 automatically adjusts from SD to HD color space and gamma. The built-in Proc Amp provides adjustment of signal parameters with controls for Video, Chroma and Pedestal. The upconverted output is timeable with respect to the reference input. When converting to film rate (1080sF/23.98) formats, 3:2 pulldown cadence is automatically detected and backed out when present in the input.

The 7910 can be configured locally or controlled and configured remotely with Avenue 5050 Touch Screen, Avenue Tabletop Control Panel, Avenue Express Panel, or Avenue PC Software. Alarm generation, configurable user levels, module lock-out, and customizable menus are just some of the tools included in the Avenue control system.

Metadata

HD closed captioning is carried in data packets in the vertical interval ancillary data space. The 7910 properly translates between traditional SD captioning (line 21 or 23) and HD caption data so that closed-captioning content is converted transparently between video standards and formats.

Automatic Aspect Ratio Conversion

The 7910 supports AFD (Active Format Description) to mark or identify the aspect ratio of the video content. These flags are generated at the output of the module, and they are read at the input. This allows the up and downconversion process to adapt automatically to material that is already in letterbox or pillarbox form in order to produce the most appropriate conversion.

Audio Options

When an audio sub module is installed, audio is automatically delayed as needed to compensate for the video processing in the 7910. For complete audio processing, choose from three different audio sub modules. Sub modules plug onto the 7910 board and do not take up a slot in the frame.

The 8415 is an eight-channel audio sub module with AES I/O that provides management of embedded audio in the processing path, or supports audio embedding/disembedding alongside the video processing elements. Embedded audio is safely bypassed around the video frame store with the lip sync preserved. Level adjustments and channel shuffling are accessed through the built-in audio mixer. The 9670 Automatic Gain Control option can be added to the 8415. All audio processing is performed at full 24 bit resolution.

The 7610 provides carriage of up to eight channels of embedded audio through the format conversion process. Embedded audio in the input signal is delayed to match the video delay and preserve lip sync. The delayed content is reinserted in the video output. No level adjustment or channel swapping is provided.
