摘要： A system and method for effectuating fast channel change in an adaptive streaming environment. A plurality of adjacent channels may be predicted relative to a current streaming channel engaged by a client device. Upon prioritizing the adjacent channels, the client device may be configured to pre-fetch metadata and initialization information for a subset of the prioritized adjacent channels based on bandwidth conditions, video player buffer status, etc. When a channel is changed, the client device is operative to use the pre-fetched data to quickly obtain encoded media content at a select bitrate for rendering.

摘要： A recording device and a method are described herein that provide a network-based personal video recording service utilizing adaptive bit rate technology for a plurality of users. In operation, the recording device records at a minimum a single bit rate (one set of segmented files) of the broadcast content within each user's network personal video recorder storage unit. Plus, the recording device stores the other bit rates (remaining sets of segmented files) in a central storage location or some other storage location.

摘要： A streaming policy management system and method wherein bandwidth may be allocated based on external device information received from a streaming client device connected to one or more external audio/video (A/V) devices. When a streaming network back office receives a request from the streaming client device for delivery of a particular content, wherein the request includes external device information of one or more external A/V devices connected to the streaming client device, a bandwidth is determined for streaming the particular content to the streaming client device and a request may be made to a content delivery network to create a distribution pipe having the bandwidth to accommodate the delivery of the particular content. A manifest file is provided to the streaming client device that includes one or more pointers that point to content segments of the particular content.

摘要： A system and method for effectuating channel changes in a multicast adaptive bitrate (MABR) streaming network using a dedicated bandwidth pipe for burst transmitting a requested channel's data. A video management agent is configured to stitch burst-transmitted data with the regular channel stream during the channel change to generate a hybrid stream, which is multicast streamed toward the requesting device. Once the data from the regular channel stream is properly joined, burst transmission ceases and the bandwidth consumed for sending burst-transmitted data is released.

摘要： A scheme for managing ABR streaming of content in a wireless radio network environment that may have radio white spot areas. Upon determining that the wireless UE device executing an ABR client application is in a radio white spot area, the current ABR streaming session may be suspended at a particular segment. Thereafter, playback of other content locally cached at the wireless UE device may be commenced in lieu of the ABR media segments. When the wireless UE device exits the radio white spot area, the ABR streaming session may be resumed from a point adjacent to the particular segment where the ABR streaming session was suspended.

摘要： Apparatuses and methods control communication of content streams through a content distribution network. A data repository is accessed to retrieve information which identifies a group of user equipment nodes that are registered with one of a plurality of subscriber accounts and which further identifies weight values that are associated with the group of the user equipment nodes. Communication bit rates that are provided by a weighted fair queuing scheduler node to individual ones of a group of the content streams within bandwidth allocated to a virtual pipe for carrying the group of the content streams through the content distribution network to the group of the user equipment nodes, are regulated responsive to the weight values associated with the group of the user equipment nodes. Weighted fair queuing scheduling can thereby be provided at a virtual pipe level and, furthermore, at a user equipment node level.

摘要： A system and method that utilize a learning system to maintain a set of geographical locations indicating an area where network data coverage is poor. When it is determined that a client device is moving towards such an area, the client is forced or instructed to switch to a lower delivery bitrate for video segments in order to force the client's Adaptive Bit Rate (ABR) playback buffer to fill itself with enough low-quality video segments to enable the client to cross the area without video playback interruption. Thus, the client mobile device may be preemptively forced to choose the lowest bitrate specified in a manifest file for the delivered video segments as the bitrate for downloading video segments when approaching the poor coverage area. Hence, the client device can maintain a minimum level of Quality of Service (QoS) when moving through network areas with poor data coverage.

摘要： A scheme for optimizing segment sizes for an adaptive bitrate (ABR) streaming client engaged in a current ABR streaming session. In one implementation, a determination is made whether a wireless UE device executing the ABR streaming client is approaching a radio white spot area. If so, a video buffer of the ABR client is configured to preload a fixed number of segments having an adjusted size depending on the duration of the radio white spot area. The preloaded segments may comprise lower quality video segments, and as the wireless UE device exits the radio white spot area, the segment size and/or bitrates may be restored depending on the signal quality.

摘要： A scheme for modulating an adaptive bitrate (ABR) streaming client engaged in a current ABR streaming session. In one implementation, a determination is made whether a wireless UE device executing the ABR streaming client is approaching a radio white spot area. If so, a video buffer of the ABR client is configured to preload lower quality video segments to last for the duration of the radio white spot area. One or more ABR client controls may be selectively deactivated while the wireless UE device is in the radio white spot area.
