The Gearbox DVB-T+T2 8 Tuners/IP 52ch is an MPEG-2 to H.264 transcoder or transcaler. It receives multiple DVB-T or DVB-T2 transport streams, transcodes them to H.264 or optional H.265, and outputs them to an IP network. Resulting streams can be viewed with standard transport stream compatible set-top boxes, streaming video, smart phones, or software clients such as VLC or JW Player. The system receives transport streams, demultiplexes the requested services and streams these services using UDP, RTP, RTMP, Adaptive, or HTTP via IP networks as either IP multicast or IP unicast streams.
Typical H.264 dedicated transcodes are up to 52 SD streams, or 13 1080i/p streams, or 20 720p60 streams. Optional H.265 transcodes are up to 20 SD streams, or 3 1080i/p streams, or 5 720p60 streams.
The system supports 50 HLS users natively. An optional built-in Atlas ™ server supports 1,000+ simultaneous HLS, DASH, and/or RTMP users. The Gearbox also supports RTMP, HTTP, and Live Streaming and works with Atlas™, Wowza®, and Adobe® Flash® servers. Audio output is AAC, MPEG-1 Layer II, Optional MP3, and/or optional “SurCode for Dolby Digital” AC-3.
The Gearbox supports rotating key servers like Verimatrix® VCAS™ and performs AES-128 encryption. Support for Variable Bit Rate (VBR) encoding maximizes adaptive streaming video quality and bandwidth efficiency. The Linux® based system relies on an Intel® Dual 18 Core CPU for encoding. We have optimized the encoder to obtain Telco grade reliability.
A higher end system, the Gearbox II T+T2 16 Tuners/IP 104ch, is also available. For the Gearbox II, typical H.264 dedicated transcodes are up to 104 SD streams, or 26 1080i/p streams, or 40 720p60 streams. Optional H.265 transcodes are up to 40 SD streams, or 6 1080i/p streams, or 10 720p60 streams.
