A method of selective pre-caching content fragments is disclosed. The method comprises receiving and analyzing, by an analytics engine, environment data pertaining to a wireless communication device and, based on the analyzing and based on a media presentation response, determining, by a pre-cache manager, an amount of fragments to provide to the wireless communication device for pre-caching to enable playback of the content at a certain quality. The method also comprises selecting, by the pre-cache manager, a subset of fragments of the content based on the determined amount of fragments and sending, by the computer system, the subset of fragments to the wireless communication device. The wireless communication device pre-caches the subset of fragments and presents the content using the cached subset of fragments and remaining fragments received from a content delivery network. The method further comprises receiving, by the analytics engine, playback data from the content delivery network.

The method comprises:—receiving, at a rendering system (101), from a plurality user devices (102-1,102-2,102-3), a plurality of cast requests over a home network (110) for casting data from a cast device (106) communicatively coupled to a first network (108) and a third network (120), onto a plurality display devices (130-1, 130-2, 130-3) communicatively coupled to the home network (110);—transmitting the cast request over a second network (114) to a casting system (104), wherein the casting system (104) is coupled with the cast device (106) through the third network (120);—receiving, in response to transmitting, from the casting system (104) and over a dedicated network (115), the requested data, wherein the data is provided to the casting system (104) by the cast device (106) and the data is obtained by the cast device (106) over the first network (108) and wherein the data over the dedicated network (115) are transmitting at a dynamically changing transfer rate and wherein the dynamically changing transfer is based on a real time available bandwidth of the dedicated network (115).

Systems and methods to enable grouping and routing of data packets are disclosed. Packets that together make up a data or content item may include grouping information that identifies or classifies the packets into a group. Grouping information may further contain information regarding maximum packet drop thresholds and instructions for a network device to follow if such a threshold is approached or exceeded. Network devices may receive and process the grouping information associated with packet groups and act in accordance with any given instructions. Network devices may intelligently decide to drop packets of one group to meet delivery thresholds for another group, including dropping all packets if necessary, or drop packets from several groups to meet delivery thresholds for all received groups. Network devices may notify other network devices about dropped packets and packet groups.

A data packet transmission method includes receiving, by a first network element, a first data packet of a first service from an application server. The method also includes determining, by the first network element, first sequence information of a second data packet. The second data packet is a to-be-discarded data packet of the first service. The first sequence information indicates a sequence of the second data packet. The method further includes determining, by the first network element, a third data packet. The third data packet includes the first sequence information. The method additionally includes sending, by the first network element, the third data packet to a terminal device.

Computer-implemented methods for hosting online video games are provided. One method includes generating a plurality of video frames. The method includes initiating a sending of each one of the plurality of video frames to a client. Each of the video frames that is sent is compressed. The method includes stopping the compression and sending of video frames when one of the plurality of video frames is taking longer than a frame time to compress and send. A frame time is defined as one over a frame rate, and wherein stopping the compression of video frames includes ignoring said video frames by an encoder. The method includes continuing to compress and send audio data to the client when one or more of said plurality of video frames are not sent to the client.

A data relay apparatus arranged between a client apparatus and a server apparatus that delivers content, discriminates a packet based on a data size thereof, the packet transmitted from the client apparatus to the server apparatus, and detects re-buffering based on a frequency of transmission of a predetermined packet discriminated.

Systems and methods for providing timing information from a R-MACHPHY device to a video core while the R-MACPHY device receives video data from the video core while operating in asynchronous mode. In some embodiments, the R-MACPHY device may alternately and selectively configure its mode of operation to alternate between synchronous mode and asynchronous mode, and provide the timing information to the video core when it switches to asynchronous mode.

One embodiment provides a video transport system. The video transport system includes graphics processing circuitry to generate a video transport unit (TU) corresponding to a scan line of a first video frame that is unchanged from a second video frame, wherein the video TU includes a control sequence and an unchanged data payload corresponding to a defined number of pixels of the scan line of the first video frame. The video transport system of this embodiment also includes source tunneling bridge circuitry to generate a bus TU based on the video TU; the source tunneling bridge circuitry to parse the control sequence or the unchanged data payload of the video TU, and to generate the bus TU having a header that includes a field to identify the defined number of pixels of the unchanged data payload, and to eliminate, in whole or in part, the unchanged data payload in the bus TU.
