ALTUM AHE Encoder (HDTV MPEG-2/H.264)
ALTUM AHE is the professional video and audio H.264 (ISO/IEC 14496) / MPEG-2 (ISO/IEC 13181) family of High Definition (HDTV) encoders with support for 4:2:0 and 4:2:2 profiles (both in H.264 and MPEG-2).
ALTUM AHE has one HD-SDI/SDI video input and as audio inputs up to 8 SDI embedded mono channels and up to 4 AES/EBU channels.
ALTUM AHE supports transmission over DVB-ASI (two ports) or IP (two ports). Both transmission systems can be used simultaneously.
ALTUM AHE supports Hi422P@L4, HP@L4 and MP@L4 profiles in H.264 HD as well as 422P@HL and MP@HL profiles in MPEG-2 HD. ALTUM AHE models have different encoding profiles by default and can be upgraded with optional profiles by means of software license.
ALTUM AHE is able to work with bitrates from 250 Kbps using H.264 SD compression up to 80 Mbps using MPEG-2 HD compression or the Hi422P@L4 profile in H.264, with GOP configurable both in length and format, what makes this equipment suitable for both contribution links and content distribution.
ALTUM AHE supports 1080i and 720p at 60, 59.94 or 50 Hz.
ALTUM AHE supports several audio algorithms (depending on the model): MPEG-1 Layer II, MPEG-4 AAC (LC/HE v1, HE v2), Dolby Digital (passthrough), Dolby Digital Plus (passthrough), PCM transparent passthrough and SMPTE-302M.
ALTUM AHE is being continuously improved and due to its architecture, any enhancement can be incorporated by firmware upgrade.
ALTUM AHE with the IP 10/100/1000 BaseT connection and the integrated webserver allows remote and local control over LAN / WAN networks, with the ability to store internal events and potential alarms.
ALTUM AHE power supply can be AC or DC, and optionally it can have a redundant power supply, so AC+AC, AC+DC and DC+DC power supply configurations are possible.
