Fig. 7. You just saved $30,000 again (typical HD encoder cost for the ENG Van) by using the built-in HD Super Encoder in the ProHD camcorder. The highly cost effective BMS camera-back TX unit does not include a (expensive) built-in HD encoder, as it takes in the compressed 20Mbps HD stream from the camcorder. Easy microwave!

The BMS Microwave Camera-back unit accepts the 1394 output from the camcorder (MPEG-2 TS at 20Mbps), modulates 16-QAM and transmits COFDM in the 2GHz microwave band (12MHz channel with the 8MHz pedestal and guard bands) to the ENG Van, where a matching BMS Microwave Diversity Receiver decodes the modulation and formats the MPEG-2 TS at 20Mbps to ASI output, which is then supplied to your existing (or new) digital Eng Van-to-Studio microwave transmitter’s ASI input. You have eliminated the need for that $30,000 HD encoder in the ENG Van, and your news master control receives a live, broadcast quality full bandwidth 1280x720p60 native signal. Easy microwave!

What about CODEC latency? The ProHD MPEG-2 Super Encoder compresses the 1280x720p60 using a GOP of 12, which GOP section equals 1/5th of a second or 200mS (12 frames of total 60 frames in a second). Other manufacturers employing HDV in 1080i60 (30 frames) use GOP of 15, which GOP section equals ½ of a second or 500mS (15 frames of total 30 frames in a second). Total encode/decode latency for ProHD is marginally more than 400mS, quite acceptable in HD ENG even in live remote interviews, while the HDV 1080i60's encode/decode latency

of more than one second may be problematic.

NAB-2007 specifications

The JVC NAB-2007 is a notable entry in the world of professional broadcasting and production equipment, showcased by JVC at the National Association of Broadcasters (NAB) Show in 2007. This camcorder was designed to meet the demanding needs of videographers and broadcasters, emphasizing high-definition video quality and advanced technology.

One of the standout features of the JVC NAB-2007 is its ability to capture high-definition video in various formats. It supports both 720p and 1080i resolutions, allowing users to choose the format that best fits their production needs. This flexibility has made it a popular choice among filmmakers, event videographers, and news organizations looking for quality in their content creation.

The camcorder utilizes JVC’s advanced HD CMOS technology, which enhances image quality by providing better low-light performance and reducing noise. This is coupled with a powerful optical zoom lens that enables users to capture detailed shots from a distance, making it ideal for dynamic shoots where proximity to the subject may be limited.

Another key feature of the JVC NAB-2007 is its ergonomic design, which is crafted for ease of use during extended shooting sessions. The camera is lightweight yet robust, providing operators with comfort and stability. Additionally, the user interface is intuitive, allowing for quick adjustments to settings without disrupting the workflow.

Built-in stabilization features further enhance the usability of the JVC NAB-2007, ensuring that footage remains smooth even during handheld operation. This is particularly advantageous for documentary shoots or on-the-go filming where traditional stabilization rigs may be impractical.

Connectivity options are expansive on the JVC NAB-2007, including HDMI and component outputs, enabling seamless integration with various editing systems and broadcast environments. The camcorder also includes features for live broadcasting, making it versatile for both recorded and real-time production scenarios.

In summary, the JVC NAB-2007 encapsulates a blend of impressive features, cutting-edge technology, and user-centric design, making it a suitable choice for professionals in the broadcasting and film industries seeking reliable and high-quality performance in their equipment.
