-XC Densité Crossconversion Frame Accurate Aspect Ratio Conversion with AFD Frame accurate Aspect Ratio Conversion (ARC) can be performed automatically using signaling based on the Active Format Description (AFD) standard. AFD data can be easily in a signal by the Densité XVP or family, and by the EAP-3901 embedder. With AFD, original image information is maintained throughout the entire conversion for optimal viewing following 4:3 and 16:9 aspect ratio conversion. For example, ing three input source formats (16:9, 16:9 and 4:3 ) in a typical / hybrid plant results in six different output possibilities. However, using automatic aspect ratio control based on AFD will prevent the ARC errors that may occur with manual control. 16:9 EAP-3901 AFD inserter Routing master control 16:9 sources 16:9 Upconverted 16:9 upconvert downconvert Upconverted 4:3 Auto ARC AFD re-insert Auto ARC AFD re-insert 16:9 sources EAP-3901 AFD inserter 4:3 Downconverted 16:9 -I routing Master control EAP-3101 AFD inserter 4:3 16:9 or 16:9 4:3 sources 4:3 4:3 aspect ratio conversion with AFD 16:9 aspect ratio conversion with AFD 4:3 16:9 4:3 16:9 With AFD (desirable) 4:3 With AFD (Desirable) Full frame UP Pillarbox DOWN Full frame X Postage stamp Without AFD (undesirable) 16:9 Letterbox UP Full frame X Postage stamp Without AFD (Undesirable) 2

-XC Densité Crossconversion Flexible 5.1 Processing The can provide very versatile ing sequences, due to the flexibility of the optional s. The s include decoding, decoding, encoding, and Plus encoding, Linear Acoustic upmax 2.0 to 5.1 upmixing and automatic loudness control (ALC). Two s can be fitted to an or.

-XC Densité Crossconversion Decoding, Automatic Loudness Control, Upmixing and (AC-3) Encoding The can be combined with the DAP-1781 for the most advanced multichannel ing. As indicated in the upper diagram, this combination can provide decoding, automatic loudness control (using Linear Acoustic ing), upmixing and (AC-3) encoding, while keeping /video tracking on the output. If upmixing is not required, this can be accomplished with a single signal or card using Grass Valley ALC (lower diagram).
