Abstract: Based on a request for media content from a media client, a device identifies one or more: segments of encrypted media content; encryption keys for decrypting the segments of encrypted media content; and segments of unencrypted media content. The device determines an order for sending the one or more segments of encrypted and unencrypted media content. The device sends, to the media client, a segment of encrypted media content, according to the order for sending, along with an encryption key for decrypting the segment of encrypted media content being sent. The device sends, to the media client, a segment of unencrypted media content, according to the order for sending, along with a subsequent encryption key for decrypting a subsequent segment of encrypted media content to be sent after the segment of unencrypted content. The subsequent encryption key permits the media client to decrypt the subsequent segment of encrypted media content.

Abstract translation: 基于对来自媒体客户端的媒体内容的请求，设备识别加密的媒体内容的一个或多个：段; 用于解密加密的媒体内容的段的加密密钥; 和未加密的媒体内容的片段。 设备确定发送加密和未加密的媒体内容的一个或多个段的顺序。 该设备根据发送顺序，向媒体客户端发送一段加密的媒体内容，以及用于解密正被发送的加密的媒体内容的分段的加密密钥。 设备根据发送顺序向媒体客户端发送一段未加密的媒体内容，以及后续加密密钥，用于解密将在未加密的内容段之后发送的加密的媒体内容的后续段。 随后的加密密钥允许媒体客户端解密加密的媒体内容的后续段。
