CPIX API Guide

Overview

The CPIX API is an API implemented in accordance with the Content Protection Information Exchange Format (CPIX) Standard Guide as defined by the DASH Industry Forum. It defines specifications that link the keys required to apply multi-DRM in the process of packaging media contents. With this API, PallyCon Multi DRM can be easily linked with encoder/transcoder solution supporting CPIX based key exchange.

CPIX API Types

PallyCon Multi DRM can be integrated with the following types of CPIX API depending on the implementation subject of API.

  • PallyCon CPIX API: The CPIX API implemented by PallyCon, allowing encoder/transcoder solution vendors to work with PallyCon Multi DRM with the corresponding API.

  • SPEKE API: The CPIX API implemented by AWS Elemental, which is pre-integrated with PallyCon to easily apply PallyCon Multi DRM to MediaPackage or MediaConvert products of AWS Elemental Media Service. For more information about SPEKE API integration, please refer to the guide.

  • Anevia CPIX API: The CPIX API implemented by Anevia. It can be easily applied to PallyCon Multi DRM with Anevia NEA-DVR solution.

PallyCon CPIX API

This API is implemented by PallyCon according to the CPIX implementation guide of DASH-IF.

Please refer to the following guide for details of CPIX specification. https://dashif.org/docs/CPIX2.1/HTML/Index.html

Supported Features

PallyCon CPIX API supports the following content types and functions.

PlayReady Widevine FairPlay AES-128
DASH (key rotation supported) (key rotation supported)
HLS (key rotation supported) (NCG DRM supported)
Smooth Streaming

KMS URL Specification

PallyCon CPIX API provides the following KMS URL specifications. The enc-token at the end of the URL is an API authentication token that is generated when you sign up PallyCon service, and can be found on the PallyCon Console site.

https://kms.pallycon.com/cpix/pallycon/getKey/{enc-token}

Encoder/transcoder solution calls the above URL to get the key needed for DRM encryption. Add the CPIX data as shown in the following example to the body part of the request data, and call it by POST method.

Example for DASH live content

For live content, the API responds with a key value that is rotated according to the ContentKeyPeriodList index value.

SPEKE API

Secure Packager and Encoder Key Exchange (SPEKE) API is the CPIX API implemented by AWS Elemental and is used to interface with AWS Elemental MediaPackage or MediaConvert products. The basic specification is the same as the PallyCon CPIX API except the KMS URL. For details on SPEKE integration, please refer to the guide.

KMS URL Specification

KMS URL specification for SPEKE API is as follows. The enc-token at the end of the URL is an API authentication token that is generated when you sign up PallyCon service, and can be found on the PallyCon Console site.

https://kms.pallycon.com/cpix/getKey?enc-token={enc-token}

Anevia CPIX API

CPIX API for integration with Anevia’s NEA-DVR solution. Through this API, PallyCon multi-DRM can be applied easily to Anevia solution.

Supported Features

Multi-DRM integration via Anevia CPIX API supports the following content types and functions.

PlayReady Widevine FairPlay AES-128
DASH
HLS
Smooth Streaming

KMS URL Specification

The KMS URL specification for Anevia CPIX API is as follows. The URL generated according to the following specifications is called by the Anevia solution in GET method to get the key.

https://kms.pallycon.com/cpix/anevia/{streamingFormat}/{encToken}/{cid}
Path Description
streamFormat dash or hls. The key is issued with the drm type supported according to the streaming format type.
encToken The API authentication token that is created when you sign up for the PallyCon service. You can find it on PallyCon Console site.
cid Content ID
