    Scaling
  • Dual hardware scalers
  • Accepts 480i - 1080p video and various computer graphics resolutions
  • Edge to edge presentation with zoom, shrink and X/Y axis positioning
  • Native or scales to fixed output resolution, 1080p scaled to 1080i
    
    Encoding
  • MPEG2/H.264 Profile: MP@HL for HD, MP@ML for SD
  • 1080i, 720p, 576i, 480p, and 480i output resolution
  • MPEG2 Video Encoding bitrate 10-25 Mbps, HD, 5-6 Mbps 480i, variable bitrate if set for IP output only
  • H.264 Video Encoding bitrate 5-10 Mbps, HD, 2-4 Mbps 480i, or variable bitrate if set for IP output only
  • Converts PCM or MPEG1, Layer 2 audio to stereo AC-3, AAC or MP12, pass-through AC-3
  • SAP Dual-language capability, second audio track is MPEG1, Layer 2
  • Dual encoders can stream a simultaneous MPEG2 or H.264 QAM MPTS stream and separate IP SPTS streams, or one encoder can process an MPEG2 stream for QAM, and the second can process an H.264 IP stream
