Abstract: Roughly described, a system and method for delivering video content to a user's client device in a video-on-demand (VOD) system, which includes providing a collection of video segments, the segments having a predefined default sequence; establishing a streaming video session according to a session-oriented protocol; transmitting toward the client device a script executable by the client device, the script operable to transmit navigational codes toward the head-end equipment in response to and indicating user selection among navigational choices; beginning transmission of the video segments in the collection toward the client device in accordance with the default sequence of segments; and in response to receipt of one of the navigational codes, and without tearing down the streaming video session, altering the transmission sequence to jump to the segment that the user selected.

Abstract: Dynamically managing an operation of a content delivery network (CDN) to address excessive load upon an upload link for updating data thereto and/or upon particular portions of the CDN. A network optimizer may receive bit rate utilization data that identifies a current bit rate amount being utilized by the upload link and what digital video data is being uploaded to the CDN thereon. The network optimizer may also receive, from an analytic server, consumption information about the current load being experienced throughout different regions of the CDN. The network optimizer analyses the bit rate utilization data and the consumption information to dynamically render any changes necessary to the bit rate utilization of the upload link and to the representations of digital video propagated to some or all portions of the CDN to ensure the load remains below a predetermined threshold in both the upload link and throughout the CDN.

Abstract: Ensuring a long-term average bitrate for channels of a statistical multiplexing meets or exceeds a specified limit. An arbitrary target average bitrate for each of a set of channels of the statistical multiplexer is received. The long-term average bit rate for each channel of the statistical multiplexer is tracked. For each allocation cycle of the statistical multiplexer, bitrates to each encoder are assigned by splitting a bit allocation pool of the statistical multiplexer into a first portion and a second portion. The first portion is allocated to maximize video quality and the second portion is allocated to minimize a gap between the set of channels that are below their arbitrary target average bitrate based on the long-term average bit rate for the set of channels. Thereafter, the bit rates allocated from the first and second portions are distributed to the encoders encoding/transcoding the set of channels.

Abstract: Roughly described, a system and method for delivering video content to a user's client device in a video-on-demand (VOD) system, which includes providing a collection of video segments, the segments having a predefined default sequence; establishing a streaming video session according to a session-oriented protocol; transmitting toward the client device a script executable by the client device, the script operable to transmit navigational codes toward the head-end equipment in response to and indicating user selection among navigational choices; beginning transmission of the video segments in the collection toward the client device in accordance with the default sequence of segments; and in response to receipt of one of the navigational codes, and without tearing down the streaming video session, altering the transmission sequence to jump to the segment that the user selected.
