Techniques are disclosed for multiplexing a dynamic bit-rate video stream with an audio stream received by a client device in a manner that allows the resulting multiplexed stream to be played back without disruption, despite dynamic changes in the bit rate of the video stream that may occur. A content server may stream both a video stream and an audio stream to a client device for playback. The client device may multiplex the video and audio streams prior to them being presented to a playback engine for decoding and playback to a user.

On-device multiplexing of streaming media content

Embodiments for changing bit rates in streaming media are provided. As portions of a streaming media file are downloaded for playback, the size of the portion is compared with an expected size determined prior to initiating playback of streaming AV data. The portion of the media file may be padded such that the size of the portion matches the size specified prior to initiating playback of streaming AV data.

Bit rate stream switching

Techniques are described herein for using cryptographic elements of the Advanced Access Content System (AACS) in a client-server environment to cryptographically authenticate client applications that are executing on non-revoked AACS-compliant playback devices. The techniques described herein may be used to protect a server application from providing information to client applications executing in non-AACS-compliant or revoked environments. In one embodiment, the techniques are used to authenticate a Blu-ray Disc Java Application executing on a non-revoked AACS-compliant Blu-ray Disc Player.
