XDCAM Professional Disc FAQ's for Broadcasters
XDCAM products automatically confirm laser-writing conditions by checking the focus servo, traking servo, reflection of laser beam, and laser power. An alarm will alert you if an unusual condition is detected. Because optical recording is fundamentally different from tape recording, there is no traditional playback confidence monitoring. Approximately 10 seconds. Yes. Yes. All XDCAM decks automatically create proxy AV that is not included in the MXF file. This function also works at high data transmission speeds via the Gigabit Ethernet or i.LINK (file access mode) interface. No, it is not possible. Direct file access on the disc is provided over the i.LINK interface* (via 'file access mode'). "File access mode" over the i.LINK interface* enables such operations as Browse File Directory, Direct read, Get File, Put File, etc. Since it occurs over the i.LINK interface, all products support the featureas all XDCAM units include the i.LINK interface as part of the standard offering. Avid is supporting i.LINK (FAM) for Proxy, high resolution MPEG IMX, DVCAM and Metadata. Please check with Avid directly for their latest interoperability capability. The Compact Deck is designed to be used horizontally on a flat surface; however, the Mobile Deck and the Drive Unit can be used vertically. Currently, audio insertion cannot be performed directly on XDCAM deck products; however, it will be supported in the future. As of today, audio insertion should be done on either a nonlinear editor or an editing VTR. Fundamentally, when audio is imported through an analog or digital (SDI, AES/EBU) input, it is overwritten on the existing audio track. When audio is imported through an Ethernet or i.LINK (file access mode) port, the audio file is not overwritten. Audio file insertion should be done by an NLE. Once the original lineup was discussed with the market, the voice of the customer clearly said therw weren't enough differentially features beyond what the PDW-1500 already offered, in order to warrant the additional cost. Therefore, it was pushed back to teh engineering table, and will ultimately returns as teh true "bridge deck" to the future, including support HD. Yes, greater capacity discs are under consideration (dual layer is one of the candidates). No, dual layer disc technology is not supported by the current XDCAM HD line-up. However, it is planned that if dual layer products are introduced they will be able to handle single layer discs as well as dual layer discs, therefore protecting the single layer legacy material you record today. No. With today's technology, it is not possible due to the transfer rate. The HDCAM format is a 140 Mbps stream, while the XDCAM cameras utilize a single laser recording at 72 Mbps. | ||
