PDW-F75

PDFEmail
PDW-F75 là đầu ghi XDCAM, chức năng ghi MPEG HD với sự tương thích phát lại bằng DVCAM. Sản phẩm này có thể ghi 1080 dòng video với nhiều tốc độ khung ở tốc độ bit cao tới 35Mbps trên đĩa quang chuyên dụng. Nó cũng cung cấp bốn kênh chất lượng cao âm thanh không nén. Đầu ghi đọc PDW-F75 cho phép đọc đĩa quang 2 lớp thế hệ mới PFD50DLA có dung lượng 50 GB và cho phép ghi dữ liệu định dạng DVCAM thông qua việc sử dụng board lựa chọn thêm PDBK-104.
PDW-F75 ghi và phát đĩa quang chuyên dụng với chuẩn HD ở 1080/59,94i; 50i; 29,97P; 25P và 23,98P sử dụng bộ mã hoá “MPEG HD” sử dụng chuẩn nén công nghiệp MPEG-2 MP@HL. Ngoài ra để cho chất lượng âm thanh cao có thể sử dụng bốn kênh, 16bit, 48kHz âm thanh không nén.
