Decoder Closed Captioning Support
The Portal Server supports live streams with closed captioning. It also supports closed
captioning for MPEG-4 stored content as long as the content is recorded with closed
captioning and stored on a VOD-W server. Closed captioning is not supported for NXG
MPEG-4 stored content. The following table shows closed captioning support for VBrick
decoders/IPRs, cross-referenced by live and stored content.
