A method for managing computational resources allocated for encoding of one or more multimedia content streams for distribution in dynamic mode to viewing devices through a distribution network is proposed, which comprises, by a processing node of the distribution network: obtain, for a multimedia content stream corresponding to a channel distributed to the viewing devices, a value of a computational resource allocation criterion, wherein the computational resource allocation criterion comprises an audience measurement for the corresponding channel; and determine, based on the computational resource allocation criterion, an allocation of computational resources of a computing platform configured for encoding the multimedia content stream.

A method for monitoring video streams is proposed, which comprises: generating, by one or more source encoders, encoded multimedia content signals based on the encoding of monitored video streams respectively corresponding to one or more monitoring points along a workflow chain of a video broadcasting headend configured for one or more video channels broadcasted by the headend, and transmitting the encoded multimedia content signals to a remote monitoring device through a content distribution network.

Remote master control room monitoring

Aspects of the subject disclosure may include, for example, obtaining live video content from equipment of a media content provider, determining priority content within the live video content; segmenting the live video content into a plurality of tiles according to the priority content, and transcoding the live video content according to a type of client device. Further embodiments include determining an encoding schedule for the plurality of tiles according to the priority content, encoding the plurality of tiles according to the encoding schedule, and providing the plurality of tiles to the client device. Other embodiments are disclosed.

Methods, devices, and systems for encoding portions of video content according to priority content within live video content

Aspects of the subject disclosure may include, for example, embodiments include obtaining video content, the video content comprises a plurality of frames, monitoring, by an image sensor, a facial feature of a user to determine a visual focus of the user in relation to the video content, and detecting from a group of frames of the plurality of frames at least a reduction in movements of objects in the group of frames. Further embodiments include determining, according to the monitoring and the detecting, a measure of attention of the user within a region of the group of frames, determining that the measure of attention of the user within the region of the group of frames satisfies a threshold, and embedding in at least a portion of subsequent frames of the plurality of frames a visual advertisement in the region via a communication device. Other embodiments are disclosed.

Methods, devices, and systems for embedding visual advertisements in video content

Aspects of the subject disclosure may include, for example, a method comprising sending a first list of formats associated with media content to a client device via a network, and receiving from the client device a selection of a format from a second list of formats filtered from the first list using filtering criteria. The second list includes formats compatible with the client device. The filtering criteria can be based on performance metrics of the network and on capabilities of the client device. During presentation of the content at the client device in the selected format, transmission of the content item can be dynamically altered in response to a message that the presentation be continued in a different format. Other embodiments are disclosed.

Dynamic playlist customization by adaptive streaming client

Devices, computer-readable media, and methods for providing a timeout for an adaptive bitrate streaming video chunk download are disclosed. For example, a processing system including at least one processor may determine a first bitrate for a first segment of a video program based upon an occupancy level of a video buffer of a device, request a first video chunk of the first segment encoded at the first bitrate, determine that the first video chunk is not received within a threshold of a duration of time after the requesting of the first video chunk, and request, responsive to the determining that the first video chunk is not received within the threshold of the duration of time, a second video chunk of the first segment encoded at a second bitrate that is lower than the first bitrate.

Adaptive bitrate streaming techniques

A processing system may obtain a video chunk of a segment of a video program via a network link, the video chunk encoded at a first bitrate of a plurality of available bitrates for segments of the video program in accordance with a mapping function of buffer occupancy levels to the plurality of available bitrates, determine a bandwidth of the network link based upon the first bitrate, a length of the segment, and an elapsed time to receive the video chunk via the network link, determine that the bandwidth of the network link is between two of the plurality of available bitrates, and increase, responsive to the determining that the bandwidth of the network link is between the two of the plurality of available bitrates, a buffer occupancy threshold of the mapping function for switching to a higher one of the two of the plurality of available bitrates.

Aspects of the subject disclosure may include, for example, identifying a region of interest included in a plurality of candidate regions of interest associated with a presentation of a first content item on a user equipment, wherein the first content item includes a panoramic video, comparing first metadata associated with the region of interest to a plurality of metadata associated with a plurality of secondary content items, responsive to the comparing, identifying a second content item included in the plurality of secondary content items, wherein the identifying of the second content item is based on a distance between the first metadata and second metadata associated with the second content item being less than a threshold, and transmitting the second content item to the user equipment responsive to the identifying of the second content item. Other embodiments are disclosed.

Method and apparatus for provisioning secondary content based on primary content

Aspects of the subject disclosure may include, for example, determining a first viewpoint in response to detecting a user's head movement in viewing video content, determining a capacity of a network, determining a tile schedule for receiving tiles from a server over the network according to the first viewpoint and the capacity of the network, and providing the tile schedule to the server over the network. The server schedules transmitting of the tiles according to the tile schedule and provides the tiles to the client device according to the tile schedule. In addition, embodiments include decoding the tiles according to a decoding schedule, buffering the decoded tiles in a decoded frame buffer, detecting a change in viewpoint from the first viewpoint to a second viewpoint, selecting a portion of the decoded tiles according to the second viewpoint, and presenting the selected tiles. Other embodiments are disclosed.
