Encrypted streams to receivers

摘要

Techniques to ensure that a content stream will be encrypted prior to it being served it to the stream receiver if either the stream receiver returned an initial status to the stream caster indicating that only encrypted streams will be accepted or if the user of the stream caster optioned that only encrypted streams will be cast. The invention consists of a stream casting device capable of locally sourcing and encrypting streams, a content stream server capable of sourcing encrypted streams and encrypting streams on the fly, a stream receiver device, and software applications and/or hardware devices to manage key exchanges, encryption, and decryption across the devices serving streams, and stream receiving devices. The casted streams, residing on either a content stream server or on the stream casting devices will be encrypted prior to being served. Encrypted streams can be encrypted at the time they are served to the stream receiver or may have been previously encrypted prior to a key exchange between the stream receiver and the device serving the content stream.

1. A method of playing content from a remote device, comprising:
receiving a content list of content that can be played, said content being content that is on a remote device and displaying said list to a user; receiving a selection from the list by said user of selected content to be received from the remote device; displaying a dialog to a user, querying the user about whether the user desires encryption of the selected content; receiving an answer from the user about whether the user desires the encryption of the selected content; if the user does not indicate that the content should be encrypted, then requesting streaming of clear content from said remote device; and if the user does indicate the content should be encrypted, then commanding carrying out of a key exchange and commanding the content to be sent encrypted.
