A method and apparatus for controlling a gain of an amplifier of a cable modem operating in a full duplex (FDX) mode. A cable modem includes an amplifier configured to amplify a received signal, a power meter configured to measure a power of the received signal on a plurality of channels, and a control unit configured to estimate a maximum expected power to receive on the plurality of channels based on the measured power and set a gain of the amplifier based on the maximum expected power. The cable modem is configured to operate in a full duplex mode. The channels include a full duplex upstream channel, a full duplex downstream channel, and a legacy downstream channel. The maximum expected power may be estimated via a sounding procedure. A power spectral density may be measured and the maximum expected power may be derived from the power spectral density.

A system for queuing flows to channels.

A vehicle includes a plurality of broadcast reception antennae; a speaker; and an audio-video-navigation (AVN) device electrically connected to the plurality of broadcast reception antennae and the speaker; wherein the AVN device is configured to receive broadcast signals of a plurality of different frequencies from the plurality of broadcast reception antennae, synthesize the broadcast signals of different frequencies, and provide the synthesized broadcast signal to the speaker to output a sound corresponding to the synthesized broadcast signals.

The system may include a headend and/or a hub that includes a processor that provides signals to consumer premises devices. The headend and/or the hub is configured with a headend configuration table defining broadcast video services for a desired distribution of broadcast video services, where configurating the headend configuration table is performed based upon data from a digital video configuration service that is independent of the broadcast video services.

Implementations for combining at least two video streams received from devices of a plurality of participants of a video conference into a composite video stream are described. A video conference including the video streams received from the devices of the plurality of participants is established. A capability associated with consuming at least two of the video streams is received from at least one of the devices. The at least two video streams are then combined into a composite video stream based on the capability associated with consuming the at least two video streams. The composite video stream is transmitted to the at least one of the devices.

In various implementations, modifications and/or additions to the ISOBMFF can indicate that a file that has been formatted according to the ISOBMFF, or a format derived from the ISOBMFF, includes virtual reality content. The file can include a restricted scheme information box, written into a track box in the file. The restricted scheme information box can indicate a virtual reality scheme for the contents of the track. For example, a signaling mechanism may indicate a most-viewed viewport associated with the virtual reality data.

An audio/video stream recording, storage, and delivery system 10 utilizes an Internet-based browser connection. The system 10 includes recording software 20, storage memory 30, a code generator 40, and a user interface 50. Preferably, the recording software 20 is located on the host back end 60 where it processes and records audio and video material that originates from the user front end 70 and is streamed to the host back end. The storage memory 30, which is also located on the host back end 60, stores the recorded audio and video material. The user interface 50 to the system provides a user located at the user front end 70 with remote access to a virtual recording room. The user interface 50 further enables the user to record audio and video material streamed from the user front end 70 by activating the recording software 20 located on the host back end 60. This is accomplished without requiring recording functionality on the user front end 70. The code generator 30 produces code associated with the recorded audio and video material. This code can be easily copied and pasted to an additional location 80, such as an auction website. Activating the code pasted at the additional location 80 provides access to the recorded audio and video material from the additional location while allowing the recorded audio and video material to remain stored at the host back end 60.

The present invention refers to the field of television experience in particular the simultaneous use of the portable computing device and a television to share a user's experience. The present disclosure proposes a method to create a snapshot from a video transmission received by a receiver, said receiver being connected with a portable computing device and having a screen output, said method comprising the steps of receiving a video transmission by the receiver, converting by the receiver, the video transmission into a lower-bandwidth video transmission, sending the lower-bandwidth video transmission to the portable computing device, receiving from the portable computing device to the receiver, a command to execute a snapshot, producing by the receiver a snapshot from the video transmission, sending the snapshot to the portable computing device.

The present disclosure relates to a method of transmitting multimedia content in a broadcast communication system, and comprises the steps of: identifying protocol information mapped for each service corresponding to multimedia content; transmitting service-related information including the identified protocol information mapped for each service; and transmitting multimedia content corresponding to related services to a receiving side by using the identified protocol.

An entry device for communicating external network signals between an in-home network and an external network, for communicating in-home network signals within the in-home network, and for preventing the in-home network signals from being communicated from the in-home network to the external network, the entry device includes a signal attenuation and communication device comprising one or more directional couplers, the signal attenuation and communication device being configured to permit upstream and downstream external network signals to communicate between an entry port and a first network work, and between the entry port and a second network port, and to block and permit communication of in-home network signals between the first network port, the second network port, and the entry port at least partially depending on a direction in which the in-home network signals are travelling.
