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: An exemplary method includes a digital advertisement insertion optimization system accessing data that indicates a playback return position at which playback of a media program is to be resumed following insertion of an advertisement in the media program when a first media file comprising the media program encoded in a first media format is used for playback of the media program, analyzing a second media file comprising the media program encoded in a second media format to identify a set of key frames within the second media file, selecting a key frame from the identified set of key frames; and generating data that indicates a new playback return position at which playback of the media program is to be resumed following insertion of an advertisement when the second media file is used for playback of the media program.
