Filed:

May 20, 2011

Appl. No.:

13/112215

Inventors:

David IRVIN - Baldwin City KS, US
Todd Andrew FRYER - Liberty MO, US
Nicholas A. NICAS - Blue Springs MO, US

International Classification:

H02B 99/00
B60Q 1/00

US Classification:

315 84, 290 1 R

Abstract:

Methods, apparatuses, and products passively generate electrical energy from waste heat. Electronic components in cabinets generate waste heat that is used to illuminate an interior of a cabinet. A thermovoltaic semiconductor detects a temperature differential between a pair of terminals installed in the cabinet. The thermovoltaic semiconductor generates a low voltage output in response to the temperature differential. A power supply receives the low voltage output and produces a higher voltage for low-wattage light sources installed in the cabinet.

H04N 21/845
H04N 21/81

Abstract:

Aspects of the subject disclosure may include, for example, a method in which a processing system of a media server determines a number of media content playout periods in a media program to be presented at a client device, obtains a media content item for presentation during a playout period, and transmits the media content item for storage in a client device cache prior to presentation of the media program. The method also includes transmitting to the client device a time stamp associated with the transmitting of the media content item, and transmitting an instruction to the client device to perform buffering of streaming media during the playout period. The client device also transmits a first message indicating that the transmitting of the media content item has been performed, and a second message indicating that the presenting of the media content item has been completed. Other embodiments are disclosed.

Appl. No.:

17/060882

Inventors:

- Atlanta GA, US
David IRVIN - Baldwin City KS, US
Nick NICAS - Blue Springs CO, US

International Classification:

H04N 21/2343
H04N 21/24

Abstract:

Media content is encoded based on network quality of service parameters. For instance, quality of service parameters for a network between a media server and a media client are determined by a system. The system selects an encoder based on a list of decoders available at the media client and the quality of service parameters, and encodes at least a portion of the media via the encoder. The system can further determine settings for the encoder based on a media type, and encode the media via the encoder according to the settings. The system can detect when the media client moves to a new network, detect new quality of service parameters, and select a new encoder based on the list of decoders available at the media client, the media type, and the new quality of service parameters.

Abstract:

Aspects of the subject disclosure may include, for example, a process that encodes a number of digital signals representing image data captured by a video camera, the image data being provided by the video camera in accordance with a 4K ultra-high definition (4K-UHD) standard. The number of digital signals are provided to a multiplexing unit that outputs a multiplexed signal including a number of optical wavelengths, the multiplexed signal being transmitted on a single fiber-optic cable unidirectionally from the multiplexing unit to a presentation device. The multiplexed signal is transmitted on the single cable unidirectionally from the proximal end to the distal end. Other embodiments are disclosed.

Abstract:

Aspects of the subject disclosure may include, for example, a device that encodes digital signals representing image data captured by a video camera and provided according to a 4K ultra-high definition (4K-UHD) standard. The digital signals are transmitted as serial digital interface (SDI) streams to a wavelength-division multiplexing (WDM) unit; the WDM unit performs electrical-to-optical conversion of the SDI streams and outputs a multiplexed signal to a single fiber-optic cable. The video camera, encoding unit, and WDM unit form a combined module within a housing; the device connects to a proximal end of a single fiber-optic cable, and a distal end of the single fiber-optic cable is configurable for connection to a demultiplexer of a 4K-UHD video presentation device. The multiplexed signal is transmitted on the single fiber-optic cable unidirectionally from the proximal end to the distal end. Other embodiments are disclosed.
