TCP protocol provides reliable transmission guarantee for no loss of frame. Its bandwidth probing and congestion control will attempt to use all of the available bandwidth between the server and client, fetching content as quickly as possible while being friendly to other (TCP) traffic on the same links. The TCP output can push the stream directly to a TCP socket or to an HTTP server.
To Create a TCP Output:
- In the Zixi Broadcaster Outputs page, click
. The New Output window is displayed.
- Type in the unique identifier for this output in the Output Name.
- Select an Input Stream to be made available on this output from the adjacent drop-down list.
- Select the Show in Matrix check box to display this stream in the Matrix (see Using the Matrix). Default: Selected.
- Select TCP.
- Do one of the following:Stream to multiple destinations - you can stream the same identical stream to multiple destinations by entering the destination parameters and then clicking the "+" button to add another destination Specify the Output parameters (see Output Stream Parameters Table).Bonded link to a single destination - you can split the stream into multiple links, which will be forwarded to a single Zixi Broadcaster by selecting the Bond Links checkbox (see Broadcaster Output with Network Bonding)
- If the target is an HTTP server, select the HTTP checkbox. In this case, HTTP headers will be added to the stream.
- Enter additional parameters as necessary (see Output Stream Parameters Table).
- Click OK. The new Push TCP Output with its settings is created and now appears on the screen.

| Parameter | Description | |
|---|---|---|
| Output Parameters | Links||
Host | The destination host for the push stream.Note: additional failover destinations can be added by clicking the adjacent “+” button. | |
Port | Specify the ports to listen on for Push streams. | |
| IPHTTP | Specify the local IP address. | |
Max Bitrate (for Bond Links enabled) | Relevant for Bond Links option. Specify the max bitrate in Kbps for the specific link. | |
Bond Links | Click this checkbox to split the stream into multiple links, which will be forwarded to a single Zixi Broadcaster. | |
Backup (for Bond Links enabled) | Relevant for Bond Links option. Select this checkbox to define the link as a backup. The backup will be used only if the accumulated bandwith of the non-backup links is not sufficient. | |
Stream ID | Specify the unique Stream ID that the remote Zixi Broadcaster expects. | |
Password | Optional - Specify a string to be used at the receiving Zixi Broadcaster to authenticate that the pushing Broadcaster is allowed to push this stream. | |
Max Latency [ms] | Specify the buffer size that Zixi Broadcaster will keep for error correction. For example, 6000 milliseconds would ensure that the stream is protected for six seconds of errors in the network. Default:6000 | |
Ignore TLS certificate errors | Select this option when streaming to a trusted server that does not have a valid certificate. When this option is selected, Zixi Broadcaster will ignore the TLS certificate errors and transmit the stream to its destination. | |
Enable Encryption | Select this checkbox to encrypt the Output stream. | |
| Encryption type (for Encryption enabled) | Specify the type of Encryption (AES 128/192/256). Click Generate to generate an encryption key or enter another encryption key. | |
| Enable IFB/Talkback | Select this checkbox to enable IFB/Talkback for one-way communication from the director or assistant director to on-air talent or a remote location. Selecting the checkbox allows the decoder with a Zixi Receiver to send audio back to the encoder with a Zixi Feeder. This offers the ability to, for example, give audio feedback to the camera operator. | |
| Port | The port that will be used to send the audio feedbackIf the target is an HTTP server, select the HTTP checkbox. In this case, HTTP headers will be added to the stream. | |
Enable Decryption | Select this checkbox to enable decryption of an encrypted stream. | |
| Decryption type | If the stream has been encrypted, you can decrypt through the output by selecting this checkbox and specifying the type of encryption that was used. Select Automatic to decrypt a stream that has been encrypted using Automatic encryption. Only if the stream has not been encrypted, select None (default). Important Notice: if the stream has been encrypted you must decrypt it in the output. | |
| Decryption key | Enter the decryption key to decrypt the encrypted stream. |
