Abstract: A method and receiving device are provided that determine a synchronization byte in a plurality of transport stream packets, wherein the synchronization byte has a predetermined synchronization value. The method/receiving device receives, via a receiver, a portion of a first transport stream packet of the plurality of transport stream packets; detects, starting from the beginning of the portion of a first transport stream packet, a continuous four byte pattern that does not include the predetermined synchronization value; detects a first occurrence of a byte having the predetermined synchronization value; detects a subsequent byte separated from the first occurrence by a predetermined byte length; determines a byte value of the subsequent byte; and validates that the first occurrence is the synchronization byte based on a comparison of the byte value and the predetermined synchronization value.

Abstract: In a streaming server, companion content may be received and incorporated along with media that is streamed to clients. The companion content may originate from one of the clients, in some cases. In other cases, the companion content may originate from a source other than a client. The companion content may be any media relates to the media being streamed to the clients or directives that control the processing of the media being streamed to the clients.

Abstract: A home gateway (102) includes a receiving component (106), a reformatting (109) component, a transcoding component (107), and a transmitting component (110). The receiving component (106) can receive an emergency alert system message in a first format. The reformatting component (109) can output a reformatted emergency alert system message in a second format, wherein the reformatted emergency alert system message is based on the received emergency alert system message. The transcoding component (107) may transcode content of the received emergency alert system message. The transmitting component (110) can transmit a notification, based on the reformatted emergency alert system message, to a client device (104).

Abstract: A method performed by an apparatus provides for adaptive bit rate content delivery to one or more client devices. The method includes: receiving data presentation content encoded into a first data stream using a first set of encoding parameters, wherein the first data stream comprises a first plurality of frames corresponding to a first encoded bit rate, wherein each frame in the first plurality of frames includes as payload a portion of the data presentation content; receiving a request, for a client device, for a second data stream having a second bit rate that is lower than the first encoded bit rate; determining a first subset of the first plurality of frames, which corresponds to the second bit rate, and generating the second data stream using the first subset of the first plurality of frames, for delivering the data presentation content to the client device.

Abstract: A method of streaming multimedia data over a network to a client device is provided. At least one playlist file is downloaded using a transfer protocol, such as HLS, from a streaming server over the network for a selected multimedia presentation. The client device subscribes to an update event notification service with the streaming server or an intermediate server with respect to the at least one playlist file for the selected multimedia presentation and then listens for an update event notification. Only when such a notification is transmitted by the streaming server or the intermediate server to the client device is an updated version of the at least one playlist file downloaded by the client device from the streaming server over the network using the transfer protocol.

Abstract: A device and a method are disclosed. The device contains a network interface configured to receive a media stream, a processing device coupled to the network interface and configured to implement the method to determine an unknown media encoding format of a media stream, and a decoder device configured to decode media frames of the media stream.

Abstract: A method and apparatus for streaming multimedia data over a network is provided. A playlist file for a selected multimedia presentation is downloaded by a client device over the network from a streaming server using a transfer protocol. The playlist file provides a list of URIs for media files each providing compressed video data corresponding to a segment of the multimedia presentation. The compressed video data includes reference frames used for video compression. A data file that is associated with the playlist file is also downloaded by the client device over the network from the streaming server using a transfer protocol and provides information identifying a location, a size, and a time stamp for each the reference frames contained in the media files listed by the playlist file. This information can be used by the client device to perform trick plays and to switch and stitch between variant streams.
