The new HVBK-1520 Format Converter Board for the HVR-1500 Digital HD Videocassette Recorder. This new optional interface board greatly enhances the functionality of the HVR-1500, adding a range of conversion capabilities that allow DV recordings to be up-converted to 1080i or 720P signals, and 1080i HDVT recordings to be cross-converted to 720P signals. By adding this board to the already fully functional HVR-1500, DV and HDV assets can be integrated into the same HD editing workflow, and also offers the flexibility to choose between 1080i and 720P. With this optional HVBK-1520 Format Converter Board installed, the HVR-1500 gains an up-conversion capability that allows DV recordings and Standard Definition signals fed to the HVR-1500 to be converted to 1080i or 720P signals and output from the HD-SDI interface. When up-converting DV recordings, the aspect ratio displayed can be converted from 4:3 to 16:9. Display modes can be selected from among Squeeze, Edge Crop, or Letterbox modes. The HVBK-1520 Format Converter Board additionally enhances the HVR-1500 with a cross-conversion capability that allows 1080i recordings to be converted to 720P signals, as well as 720/30P (29.97 frames/s) recordings to be converted to 1080/60i (59.94 fields/s) signals, and output these signals from the HD-SDI interface. Note: Cross-conversion via i.LINK I/O is not supported. Also, up-converted recording is not supported. Additionally, cross conversion is not available from HD Component output - recorded format is output without conversion.
