Media content presentation systems and methods are operable to present media content received by a media device, wherein the media device comprises a plurality of tuner systems. An exemplary embodiment tunes the plurality of tuners to receive different broadcasting media content streams each comprising a streaming media content event; communicates the streaming media content events from the receiving tuner to a corresponding tuner buffer of the tuner system; and stores a portion of the streaming media content events into the corresponding tuner buffers. When a user selection is received for presentation of one of the streaming media content events, the selected one of the streaming media content events are presented to a user of the media device.

A system and method is provided for performing lossless switching in a redundant multicast network. An exemplary method includes receiving a primary media stream and a redundant media stream over different forwarding network paths by network ports of a receiver communicatively coupled to an A/V device. Furthermore, the receiver outputs media data of the media streams to the A/V device to be presented thereon. In response to a control signal to switch the receiver to a new primary media stream, the method disconnected either the primary ort the redundant media streams from the respective network port of the receiver receiving that stream. Furthermore, the method includes controlling the disconnected network port to receive the new primary media stream and then outputting media data of the new primary media stream to the A/V device to be presented thereon.

Examples of the systems and methods described herein relate to reducing latency issues associated with playing online digital video on client devices. An example method includes: determining a likelihood that a user will trigger presentment of video content within a portion of digital content, and when the likelihood is determined to exceed a threshold, obtaining a video tag that identifies the video content or caching a portion of the video content prior to presentment of the video content.

Systems, apparatuses, and methods are described for a user device controlling a playback buffer to reduce latency in a service change.

To reduce latency in streaming media a playlist requested from a content delivery network may be modified to have modified segmentation. After receiving the playlist from the content delivery network, the location of one or more I-frames in each segment in the playlist may be determined and these locations may be used to generate the modified playlist. The modified playlist may then be sent to a client device. Media segments may be modified in accordance with the modified segmentation of the modified playlist to generate modified media segments that can be sent to the client device.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. When automatically switching from presenting a service on a first frequency to a second frequency such as when a mobile receiver is moving through a boundary region between two broadcasters, the current broadcaster application is notified and depending on the context, may continue executing or send data to the new broadcaster application.

A method for managing reception of digital contents by a management device suitable for receiving a command for selecting a content, termed the main content, arising from a control device. The management device is suitable for requesting reception of the main content and of other digital contents, termed secondary contents. It is also suitable for receiving the data streams representative of the requested contents, and for requesting the retrieval of the main content. According to the method, in the course of retrieval of the main content, a detection of an activity related to the control device triggers a request suitable for requesting reception of the secondary contents.

Systems and methods are disclosed herein for adaptively buffering content of a media asset from a media source when a different media asset from a different media source is being played at user equipment. The media guidance application may predict when and which channel or other media source the user is likely to switch to and then buffer content from the predicted channel or other media source accordingly. The pre-tuning buffering may enhance the user experience by reduce tuning latency when the user switches channels.

One aspect of the instant application facilitates reduction of multicast group join latency. During operation, the system can receive, at a network device, a first multicast group leave packet corresponding to a first multicast group. In response to receiving a first multicast group leave packet from an IPTV client, the system can simulate a second multicast group join on behalf of the IPTV client by updating, based on a predictive model, at least an entry in a table maintained in hardware with a next likely multicast group that the IPTV client is likely to join; and sending a simulated second multicast group join packet for initiating an IPTV stream associated with the next likely multicast group. In response to receiving an actual second multicast group join packet from the IPTV client, the system can facilitate the IPTV stream to the IPTV client, thereby reducing multicast group join latency.

A predictive tuning system is disclosed in order to reduce the tuning channel delay time in a cable TV architecture. The system comprises a set-top box (STB) configured to instantiate a given number of video decoding pipelines allowing for start broadcasting a particular set of channels which include a sub-set of pre-define channels, such as the antecessor and predecessor channels which are normally pre-tuned, and other sub-set of channels chosen using a predictive algorithm. This algorithm runs locally at the user interface level of the STB suggesting the more likely channels to be watched by the user according to his past behavior according to a specific time slot of a day.
