In-stream controls for national video distribution
Systems and methods are described for delivering regional content for a lineup over a national network. A content provider may select a particular regional broadcast for inclusion in a regional service lineup. The content provider may be able to broadcast multiple, or even all, services nationally. At regional distribution centers, a multiplexer may select only those services that are desired for the region in response to in-stream signals. In some instances, a single region-specific version of a given service may be selected from multiple versions broadcasted nationally. The regional lineup, including the selected services, can then be multiplexed and transmitted to customers throughout the region.
Technologies for end of frame detection in streaming content
Technologies for end of frame marking and detection in streaming digital media content include a source computing device communicatively coupled to a destination computing device. The source computing device is configured to encode a frame of digital media content and insert an end of frame marker into a transport stream header of a network packet that includes an encoded payload corresponding to a chunk of data of the frame of digital media content. The destination computing device is configured to de-packetize received network packets and parse the transport stream headers of the received network packets to determine whether the network packet corresponds to an end of frame of the frame of digital media content. The destination computing device is further configured to transmit the encoded payloads of the received network packets to a decoder in response to a determination that the end of frame network packet has been received. Other embodiments are described and claimed.
Method and system for processing multimedia content within a metropolitan area network
A method for processing a multimedia content previously digitally encoded into an audio-video stream and transmitted from a distribution platform for the purposes of on-demand transmission to a plurality of receiving terminals includes the following steps: applying a demultiplexing function to the audio-video stream, said function being arranged to generate at least one group of data streams; applying a transformation to each data stream; segmenting each data stream; storing the at least one group of segmented data streams in a memory; carrying out, only in response to a request issued by a receiving terminal among the plurality of receiving terminals, the following steps: selecting, on the basis of the request, at least one data stream of at least one group of stored data streams; and transmitting the at least one selected data stream to the receiving terminal that issued the request.

CMAF CONTENT PREPARATION TEMPLATE USING NBMP WORKFLOW DESCRIPTION DOCUMENT FORMAT IN 5G NETWORKS
Systems, devices, and methods for media processing and streaming, including receiving content to be prepared for a 5G media streaming (5GMS) corresponding to an input Common Media Application Format (CMAF) track and a set of output CMAF tracks; determining a content preparation template (CPT), wherein the CPT includes a Network Based Media Processing (NBMP) workflow description document (WDD) which specifies an input format of the input CMAF track, and an array of task instances corresponding to the set of output CMAF tracks; preparing the content according to the CPT; and streaming the prepared content over the 5GMS network to a media streaming client.
Retaining legacy STB support with HFC plant migration to high split
Propagating a downstream (DS) Out-of-Band (OOB) signal at a frequency receivable by a set of legacy set-top boxes (STBs) while supporting enhanced upstream peak data rates. At an input of an amplifier of a physical device, a portion of the DS-OOB signal is tapped to create a tapped DS-OOB signal, which comprises both the DS-OOB signal and all other downstream signals and channels sent from a head-end to a set of customer premises equipment (CPE) via the physical device. The tapped DS-OOB signal is introduced to a band-pass filter that passes the DS-OOB signal and attenuates all other radio frequency (RF) signals to create a filtered DS-OOB signal. The filtered DS-OOB signal is amplified and coupled to a low-pass side of a high-split diplex filter to propagate onto a transmission medium coupled to the CPE. The physical device may be a high-split RF amplifier or a high-split node.

System and method of streaming content between peer devices in a broadcast environment
A system is provided for streaming broadcast media content between peer devices in a media distribution network. The system includes a virtual router panel that includes a notification service controller that receives a data communication request from two or more peer devices and a data communication handshaking controller selects a delivery protocol between the two devices based on exchanging communication candidates that identify peer addresses. A media streaming tunnel generator establishes a streaming tunnel between the first device and the second device based on the respective delivery protocol selected by the data communication handshaking controller; and an encoder packetizes video, audio and ancillary grains directly as packets of the broadcast media content to be streamed directly from the first device to the second device via the established streaming tunnel without multiplexing.
