SVT-A Supported Transcode Pairs
The transcoded output video is a Variable Bit Rate (VBR) Single Program Transport Stream (SPTS) programmed with the following data rates:
MPEG2 HD: 15-18 Mbps      H.264 HD: 7-10 Mbps
MPEG2 SD: 3.75-6 Mbps     H.264 SD: 1.5-4 MbpsNote: The programmed video VBR data rate is the average over 15 frames and may peak at ~ 1.5x between PCR cycles.
(Please download datasheet to view chart.)
Digital Tier Distribution
The SVT Advanced Transcoder ASI and IP outputs can carry multiple transcoded video programs for efficient digital tier distribution.
Network Reception and Backhaul
Receive network and live feeds via ASI and simultaneously transcode to the required digital video compression format for distribution. The ASI transport stream outputs can carry multiple transcoded programs for efficient distribution of services.
HD to SD Down-Conversion
Convert HD broadcasts to SD for support of an existing distribution infrastructure.
