摘要： Methods and apparatuses are provided for use with a client and server device connected through a communication link. The client device sends a startup request to the server device. The startup request identifies a streamable media content that is to be provided to the client device, a communication link bandwidth associated with the communication link, and an amount of the desired streamable media content that is to be provided at a bitrate greater than the encoded bitrate but no greater than about the communication link bandwidth. The server device buffers at least the amount of the streamable media content, and transmits the amount of the buffered streamable media content at the higher bitrate. The server device locates a discrete rendering point in the amount of the buffered streamable media content and initiates transmission beginning with the discrete rendering point. After transmitting the amount of the buffered streamable media content, the server device transmits subsequent portions of the streamable media content to the client device at a bitrate about equal to the encoded bitrate. The client device buffers received streamable media content, and subsequently renders the buffered streamed media content.

摘要： A source device permits a user of a remote device to access a protected file on the source device when the user of the remote device has a right to access the protected file. The user locates the protected file on the source device using the remote device and accesses the protected file using a media player on the remote device. The media player constructs a path by which the source device streams the protected file. The remote device responds to an authentication request from the source device that the user of the remote device has a right to access the protected file. The user is authenticated to confirm that the user of the remote device has a right to access the protected file. The protected file is streamed to the remote device via a path constructed by the remote device.
