Mechanisms are provided for replacing default advertisement streams in a media stream with replacement advertisement streams. User profile information is obtained for a particular user and/or device. A default advertisement stream is identified and replaced with advertisement streams selected using the user profile information. Timestamp information and sequence number information is maintained to allow uninterrupted delivery of the modified media stream while customizing media streams for particular users.

A media stream delivery system encodes and fragments media streams into numerous media stream fragments maintained on fragment servers. Playlist information, media data, and bandwidth adaption data is provided as box information with media stream fragments to reduce the number of client requests required to begin playback or perform a channel change. A client no longer needs to make separate requests for bandwidth adaptation data, media data, or playlist information. Playback can begin as soon as sufficient media stream fragments are received.

A content server is configured to buffer and transmit numerous live media streams to individual devices. The content server analyzes characteristics associated with the live media streams to determine timing and sequence number information. Other characteristics such as network congestion metrics, device buffer usage metrics, etc., can also be evaluated. Combined peak transmission times are determined to allow packets designated for transmission at a bandwidth usage peak to be transmitted earlier in time. Earlier packets are shifted even earlier as sequence numbers allow. This evens out bandwidth usage rates and allows improved live media stream transmission.

Mechanisms are provided for generating and modifying live media streams. A device establishes a session and requests a media stream from a content server. The content server provides the media stream to the device. The content server also obtains an insertion stream for inclusion in the media stream. Packets are removed from the media stream to allow inclusion of the insertion stream. Timestamp information and sequence number information is maintained to allow uninterrupted delivery of the modified media stream.

Mechanisms are provided to support intro stream merger and outro stream merger into a live stream without disrupting application operation. An intro merger stream corresponding to a requested live stream including multiple packets is obtained. The intro merger stream is transmitted to a device. Time and sequence number information is maintained during transmission of the intro merger stream to allow modification of the live stream using time and sequence number information. The device receives both the intro merger stream and the live stream in a single session.

Mechanisms are provided to transmit media stream bursts upon recognizing that a device buffer is low or empty. In particular examples, a content server transmits 6 seconds of video in 2 seconds in order to quickly replenish a device buffer so that the device can start playback sooner. Content server buffers for particular channels can be prefilled even before any stream is requested for that channel. The content server can transmit at a higher bit rate for a short period of time or alternatively can switch to transmitting a lower quality stream for a short period of time. A media stream burst can be provided without disrupting system operation or requiring client rebuffering.
