For TelVue Broadcast Servers to be able to communicate with Connect, they must be able to access outbound ports:
- 443 – HTTPS
- 53 – DNS
Nearly all firewalls have these outbound ports open by default.
- TLS / SSL / HTTPS – All communication to and from Connect is encrypted using a 256-bit SSL certificate from Verisign. This includes all communication from web browsers, our broadcast-server appliances, and other software clients connecting to Connect’s REST API.
- Passwords – Passwords are stored using a 512-bit, one-way, cryptographic-hash algorithm. They cannot be seen or decrypted by anyone or anything.

Embedded Closed Captioning is preserved in VOD and most Broadcast output formats when uploaded source files contain 608/708 embedded captioning.
The CloudCast Video Player and OTT Apps including Roku and Apple TV support displaying Closed Captioning for both on-demand and live streams containing embedded 608 captions. Your streaming encoder must support embedded 608 captioning for captioning to display on your live streams.
The CloudCast Video Player and OTT Apps support displaying Closed Captioning from a WebVTT, SRT, or SCC closed caption sidecar file uploaded for on-demand videos via the CMS Media Edit page.
Uploaded, sidecar caption files can be used to embed 608/708 captioning in transcoded Broadcast files for playback or sharing in the Media Exchange.
For Media without embedded captions or an available sidecar file, Connect supports Automatic Closed Captioning with advanced Custom Language Modeling that can be used to generate captions for both Broadcast and Streaming/OTT content.
