# Transcoding

### Transcoding Solutions

The migration from traditional networks to IP core networks has simplified the overall deployment overhead involved with physical equipment interoperability, but it has not reduced the challenges in making these devices understand each other. Signaling compatibility is certainly one of these challenges, but it is also very close to media compatibility, when it comes to making diverse vendor equipment and networks communicate with each other. TelcoBridges transcoding solutions are designed to overcome these challenges in IP networks by offering a wide range of vocoders packed with extensive signaling transcoding capabilities. This ideal combination offers the most efficient solution to fulfill transcoding needs for carriers, operators and enterprises while keeping CAPEX and OPEX within budget without sacrificing agility or rapid deployment.

#### IP network adaptation

Whether TelcoBridges solutions are required to resolve signaling or complex media stream transcoding, or all of these at the same time, the state-of-the-art architecture and hardware technology of the ProSBC Session Border Controller can tackle these challenges head-on. With a vast list of supported vocoders for wireline, wireless and high-definition media streams, the solution can address all possible transcoding needs. The embedded resource optimization engine included in these solutions dynamically ensures transcoding capabilities are used only when necessary to maximize the system throughput.

#### Rapid and ease of deployments

Deploying transcoding solutions to bridge devices and networks should be a painless and straightforward process for operators, carriers and enterprises. To guarantee this, TelcoBridges solutions offer multiple provisioning and monitoring interfaces for fast integration into existing network infrastructures. From legacy console configuration to RESTful API programmatic and web interface, the SBC access interfaces satisfy all operation personnel from IT network managers and on-site technicians, to Network Operations Center (NOC) engineers. Less time spent managing a network means more time to invest in delivering innovative end-customer services.

#### Carrier Grade

TelcoBridges solutions all benefit from a decade of experience in building and deploying always-on services with the highest industry standards for reliability and up-time. Targeted to carriers, operators and large enterprises around the world, TelcoBridges’ carrier grade portfolio is designed to be a worry-free experience. TelcoBridges is proud to have deployed highly available equipment in more than 100 countries around the world.

#### Cost effectiveness

Budget is always a key consideration when introducing a transcoding solution into a network. TelcoBridges’ scalable approach for transcoding media resources ensures the initial capital expense addresses not only what is required to start a project, but also allows for an adjustment of those needs down the road when the traffic grows and evolves. TelcoBridges’ transcoding solutions provide a fast Return-On-Investment (ROI) to help get more traction with new services and deployments.

ProSBC Session Border Controller is ideal for transcoding needs.

### Configurations

For ProSBC Hardware Transcoding, you need to purchase the hardware and install this in your central office. The network setup is described here:

* [ProSBC:Hardware Transcoding Network Setup](/configuration-details/configuration-by-use-case/transcoding-unit-configuration/baremetal-and-virtual-machine.md)
* [Transcoding use case with an external transcoding device](/configuration-details/configuration-by-use-case/transcoding-unit-configuration.md)

### Network interfaces & cabling

For the number of network interfaces (NICs) required per deployment topology — standalone, 1+1, and with or without an external transcoder — and how to wire the ctrl0/ctrl1 control interfaces in a High Availability system, see [Network Interface Requirements](/initial-installation/1.-instructions-by-platform/network-interface-requirements.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://prosbcdocs.telcobridges.com/use-cases/applications/transcoding.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
