Description

Thor Broadcast's compact IP to RF Gateway produces up to 4 modulated channels from UDP/RTP Transport Streams. The miniature gateway features a dedicated data port for IP UDP, RTP unicast, or multicast from IP MPEG encoders, along with a second RJ45 port strictly used for NMS monitoring and device management.

It directs the encoded TS streams into 4 agile CATV carriers, serving as a gateway. If the IP streams encoded video/audio is in a specific format such as MPEG2 or H.264, the modulated channels will maintain the same encoding format.

This unit can multiplex multiple IP streams into a single RF carrier as subchannels, provided there is available bandwidth in the RF channel (modulation dependent).

For instance, in QAM 246, J.3B has 38Mbps bandwidth available. This one RF carrier channel can accommodate 12 programs encoded at 4Mbps (38x4=12).

The 4 Ch IPRF also includes VCT - Virtual channel numbers and unique channel names. All these settings are configured via the NMS port in conjunction with creating channels in RF.

All RF standards are preloaded into the modulator, enabling you to select any modulation standard you need, regardless of your location in the world.

It is an ideal solution for applications requiring a low-cost and straightforward approach to IP to cable conversion for local TV systems

ASI to QAM or ATSC CATV RF Modulator

Digital modulator with ASI Input and CATV RF output - QAM or ATSC or DVB-T or ISDBT (model dependent) Also IP output in UDP/RTP/RTSP - SPTS/MPTS, Unicast/Multicast

IP to CATV RF Digital QAM Gateway with the MPEG4 H.264 to MPEG2 transcoding option - 64 Channel.

The H-HERMES-64 can receive up to 64 IP UDP streams encoded in H.264 video, trans-code them to MPEG2 with AC3 Dolby audio, and modulate them on a 16-channel CATV RF QAM or ATSC spectrum. An example application is to use incoming streams from the Technicolor COM3000 or any multi-channel HDMI H.264 IP encoder, and transcode them to the format standard supported in the USA, Canada, and Mexico in order to be able to receive them on any televisions' tuner over the existing coaxial network,
