Media receiver hub
View Patent ↗A media receiver hub receives wireless signals from multiple sources (e.g., satellite signals from multiple satellites) and provides the signals to end devices over a local network. According to an example embodiment, a satellite hub is responsive to channel input selections received from end devices by selecting channels from within received satellite signals, and by converting each channel into a format amenable for delivery to and use at an end device requesting the channel. The converted channels are communicated to the end devices over a network that also facilitates communications between the devices, by restricting the communications to using a portion of the available bandwidth of the network, reserving bandwidth for communications with and/or between the end devices (or other network devices).
1. A satellite receiver hub comprising:
a frequency translation module configured to select a subset of channels from a multitude of satellite broadcast channels in response to channel selection inputs received over a local network from end devices requesting the subset of channels, and to frequency translate the subset of channels to a portion of the L band in a restricted frequency range of 10-600 MHz;
a demodulator circuit configured to demodulate the frequency-translated channels and to generate transport streams for each channel,
a packet identification (PID) filter and multiplexer circuit configured to convert the respective transport streams into a multiplexed output stream for use at respective end devices requesting the subset of channels and to filter the respective transport streams to select the desired PIDs and to provide the respective transport streams as the multiplexed output stream based on the type of end device communications to be utilized, and
a network-specific interface circuit configured to receive the multiplexed output stream from the PID filter and multiplexer circuit, to modulate the multiplexed output stream onto the L band in a restricted frequency range of 950-1100 MHz, and to communicate the multiplexed output stream to the end devices on the local network over which the end devices communicate to one another.
2. The satellite receiver hub of claim 1 , wherein PID filter and multiplexer circuit is configured to convert the respective transport streams into a multiplexed Internet protocol (IP) packet stream for use at respective packet-based end devices requesting the subset of channels; and
the network-specific interface circuit is configured to receive the multiplexed IP packet stream from the PID filter and multiplexer circuit, and to communicate the multiplexed IP packet stream over a packet-based local area network.
3. A system for communicating broadcast satellite signals over a local packet-based network, the system comprising:
a plurality of end devices configured to communicate media content with one another over the local packet-based network using a packet-based communications protocol;
a satellite receiver hub configured to
select a subset of channels from a multitude of satellite broadcast channels in response to channel selection inputs received over the local packet-based network from the plurality of end devices requesting the subset of channels, and frequency translate the subset of channels to a portion of the L band in a restricted frequency range of 10-600 MHz;
demodulate the frequency-translated channels and to generate transport streams for each channel,
convert the respective transport streams into a multiplexed output stream for use at respective end devices requesting the subset of channels and filter the respective transport streams to select the desired packet identification and provide the respective transport streams as the multiplexed output stream based on the type of end device communications to be utilized, and
receive the multiplexed output stream, modulate the multiplexed output stream onto the L band in a restricted frequency range of 950-1100 MHz, and communicate the multiplexed output stream to the plurality of end devices on the local packet-based network over which the plurality of end devices communicate to one another.
4. The system of claim 3 , wherein
the local packet-based network is an Internet protocol (IP) network, and
the satellite receiver hub converts each channel for a particular end device into a packet-based data stream for communication on the IP network, with a destination address of the particular end device included with each packet in the packet-based data stream.
5. The system of claim 3 , wherein
the local packet-based network is an Internet protocol (IP) network operating on a cable network that supports both L band data communications and IP-based packet communications, and
the satellite receiver hub converts each channel for a particular end device into a transport stream having a predefined frequency that is specific to the particular end device and that is within a restricted frequency available on the cable network, reserving a remaining frequency range on the cable network for IP-based packet communications.
6. The system of claim 3 , wherein at least one of the plurality of end devices is configured to respond to requests for media content stored at the respective end device to another one of the plurality of end devices over the local packet-based network.
7. The system of claim 3 , wherein at least one of the plurality of end devices is a digital media server configured to receive and store converted data streams received from the satellite receiver hub, and to deliver the stored converted data streams to other end devices in response to requests therefrom.
