SECURE PROGRESSIVE DOWNLOAD FOR MEDIA CONTENT PLAYBACK

摘要

In embodiments of secure progressive download for media content playback, a client device (128) implements a media player (142) and a proxy application (144). The proxy application is implemented to receive media content (136) from a media server (126), and the media player controls playback of media content (148) on the client device. The proxy application receives the media content (136) encrypted and formatted by the media server for playback by the media player, and the proxy application initiates storing segments of the media content (148) as encrypted media content on the client device. The proxy application also requests an encryption key (124) to decrypt the encrypted media content for playback by the media player. The proxy application receives the encryption key from a key server (122) and stores the encryption key on the client device to decrypt the encrypted media content when requested by the media player.
