The BKPF-L642 is an encoder board that converts a component 4:2:2 serial digital signal into an NTSC/PAL composite analog signal. It features 10-bit processing, 2x over sampling and a line synchronizer.
In conjunction with the BKPF-L641 4:2:2 to NTSC/PAL decorder board, the color frame ID extractor function avoids the reverse color framing that may be generated by the encode/decode chain. It maintains ancillary data within the VBI. An internal test signal generator is provided for maintenance purposes. The BKPF-L642 uses 10-bit conversion for quality-critical application such as distribution or on-air transmission applications. The BKPF-L Series function boards install in the PFV-L Series Interface Units in any combination with other BKPF-L Series function boards.
