Paralinx Capacidades y limitaciones del sistema de transmisión inalámbrica de alta definición sin compresión
Tiene 14 años. Es posible que el equipo y los precios hayan cambiado desde entonces.
Lo que encontró el hilo
- El transmisor Arrow es compacto y alimentado a través de USB, con un receptor sobre el tamaño de una tarjeta 3x5 y 1 pulgada de espesor, ambos diseñados para uso portátil en conjuntos.
- 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.
- Transmission is uncompressed with sub-2ms latency, allowing reliable on-monitor scoping and histogram readings for camera operators.
- 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 adding converter boxes like a Decimator 2 on both ends, significantly increasing system cost and complexity.
- Total system cost with necessary converters reaches approximately $1,985, which is still notably less expensive than competing wireless systems like new Canatrans or Switronix Recon.
- If a camera has HDMI output, the Arrow can connect directly without requiring external converters like a 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.
Depende de
- 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.
