:: خيارات لاسلكية للإرسال في إطار مبادرة HD-SDI للأحداث الحية مع Sony آلة تصوير من طراز XDCAM EX3
مضى على هذا 16 سنة. قد تكون المعدات والأسعار قد تغيّرت منذ ذلك الحين.
ما توصّل إليه النقاش
- والنظم اللاسلكية المنخفضة التكلفة مثل الـ IDX كاموايف و Transvideo Boxx مناسبة لرصد الثقة والمساعدة بالفيديو، ولكنها تفتقر إلى ما يكفي من النطاق والقوة للتسجيل الحي على مستوى البث والتصوير في أماكن أكبر.
- Professional COFDM wireless systems capable of reliable HD-SDI transmission for live events start at approximately 50000 USD and can reach 100000 USD or more.
- The IDX Camwave 5HD supports multicasting to multiple receivers, allowing coverage across large venues by positioning receivers at different locations such as lighting rigs, front of house, and mid-stage positions, with reported range around 150 feet.
- The Boxx Meridian system demonstrates reliable performance in large venue applications, maintaining signal integrity across extensive distances and complex environments like theaters with multiple cameras.
- Power management for wireless transmitter units requires careful planning, with options including powering from the camera or using dedicated power breakout boxes.
- The Transvideo Boxx system shows consistently better signal quality for live work compared to the IDX Camwave, according to field experience reports.
- Vision control positioned behind stage or screen in live events means wireless receivers do not need to maintain extreme range from the camera position.
