TelVue ProVue® Release Notes
The TelVue ProVue is a reliable, user-friendly IP video decoder that decodes MPEG-2 and H.264 transport streams into broadcast quality SD/HD-SDI, Analog, HDMI or IP video for processing and broadcast. Operation is as simple as selecting your input source IP stream and desired output format. The TelVue ProVue SDI model supports SD/HD-SDI outputs, and the TelVue ProVue Analog model supports Composite, Component, and HDMI outputs. IP Output as encoded Transport stream is available as an option on certain models.
