This notice is to announce some possible issues with the display output of downstream settop boxes when using the D9859 within certain configurations and with certain settings:
Scenario 1: MPEG4HD to MPEG2HD 16:9
We recently found problems on older settop boxes due to the way the D9859 signals the HD content downstream. Those boxes could end up displaying the content in a letterbox format versus a full scale output which would be expected.
Cisco is working on a maintenance release to solve this specific application by adding the proper signaling so older settops can execute the proper output format.
Scenario 2: MPEG4HD to MPEG2SD
It is advised to avoid the mode “None”, "4:3 P/B", "16:9 Scale" when transcoding from an input stream MPEG4 HD with 16:9 Aspect Ratio to MPEG2 SD
Default mode is “None” on the D9859.
For this scenario, we advise 4:3 CCO, 16:9 LB or 14:9 as a fixed setting.
For D9859, “None”, “4:3 P/B” and “16:9 Scale" currently result in letter box display, signaled downstream as 4:3
Note that on the D9858, “None”, "4:3 P/B", "16:9 Scale" resulted in a 16:9 compressed picture, signaled downstream as 4:3
The D9859 Aspect Ratio Conversion options are:
None, Auto, Auto AFD, 16:9 L/B, 4:3 P/B, 14:9, 4:3 CCO, and 16:9 Scale. See D9859 User Manual for full details.
WebGUI setup: change "none" to 4:3 CCO, 16:9 LB or 14:9
