Paralinx تأمين قدرات وقيود نظام البث اللاسلكي
مضى على هذا 14 سنة. قد تكون المعدات والأسعار قد تغيّرت منذ ذلك الحين.
ما توصّل إليه النقاش
- The Arrow transmitter is compact and powered via USB, with a receiver about the size of a 3x5 card and 1 inch fish, both designed for portable use on sets.
- The system advertises 320 feet line-of-sight transmission range and 150-200 feet with obstructions, using enhanced antennas and power amplification compared to consumer WHDI sticks.
- والانتقال غير مكتظ بالبطء الفرعي 2ms، مما يتيح تحديد النطاقات التي يمكن الاعتماد عليها في المرصد وقراءات الصور الفوتوغرافية لمشغلي الكاميرات.
- The system requires 7-10 seconds to lock signal initially and the same time to recover if signal is lost during a shot, which could cause production delays.
- HDMI is the only connection type available; achieving HD-SDI compatibility requires add converter boxes like a Decimator 2 on both ends, significantly increasing system cost and complexity.
- ويبلغ مجموع تكلفة النظام مع المحولات اللازمة نحو 985 1 دولارا، وهو ما لا يزال أقل تكلفة بشكل ملحوظ من النظم اللاسلكية المتنافسة مثل الكانترانت الجديدة أو شركة Switronix Recon.
- إذا كانت الكاميرا تحتوي على ناتج HDMI، يمكن للسهم أن يتواصل مباشرة دون الحاجة إلى محولات خارجية مثل Decimator 2.
- The system was initially priced at $995 during CineGear 2012, then increased to $1,195 after the show ended.
- Multicast capability allowing one transmitter to work with multiple receivers was under development but release timeline was not provided.
يعتمد على
- Testing was limited to demonstrations at CineGear; real-world on-set performance had not been comprehensively verified at the time of discussion.
- The HDMI-only connector type makes integration into professional HD-SDI workflows difficult without additional conversion equipment.
- Manufacturer stated no plans to release an HD-SDI version, though some participants believed this position might change after seeing industry demand.
- Signal recovery time could be problematic on larger professional productions with multiple crew members monitoring video village.
- Power input via USB rather than professional power connectors like D-tap was considered less robust than industry alternatives.
- Performance of the system indoors versus outdoors had not been fully tested by participants.
