Abstract: A method of providing channel content in a broadcast content reception and distribution system includes: receiving, by a broadcast content reception device, information that identifies a channel that provides channel content, from a content player device; receiving, by the broadcast content reception device, a signal that transmits the channel content, from an antenna; receiving, by the broadcast content reception device, information that indicates a signal strength corresponding to the channel based on the signal that transmits the channel content received from the antenna; determining, by the broadcast content reception device, that the signal strength is less than or equal to a threshold value based on the information that indicates the signal strength; and transmitting, by the broadcast content reception device, a message to the content player device in response to the determining that the signal strength is less than or equal to the threshold value.

Abstract: A technique is directed to methods and systems for live streaming. In some implementations, the method includes (1) monitoring, by a bitrate feedback extension (BFE) module, a bitrate for a client device during a live streaming process; (2) in response to a bitrate change during the live streaming process, notifying, by the BFE module, the bitrate change to a buffer switch handler (BSH) module; (3) sending, by the BSH module, a request to adjust the bitrate for the client device to a media engine; and (4) switching, based on the request, a media source of the live streaming process.

Abstract: Methods and apparatuses for detecting timestamp discontinuities and video resolution discontinuities within a packet stream and marking locations of the detected discontinuities within the packet stream are described. Prior to transmission of the packet stream, an electronic device may perform timestamp discontinuity detection by acquiring a sequence of packets to be transmitted, identifying a first timestamp associated with an earliest packet within the sequence of packets, identifying a second timestamp associated with a latest packet within the sequence of packets, determining a timestamp time difference between the first timestamp and the second timestamp, determining a maximum chunk time difference based on a data rate at which the sequence of packets were encoded and a data size of the encoded packets, and detecting that a timestamp discontinuity exists within the sequence of packets if the timestamp time difference is greater than the maximum chunk time difference.

Abstract: A television receiver receives media data from a media content provider. The television receiver is also connected to a wireless network. When the television receiver receives a request via the wireless network to provide media content to an electronic device over the wireless network, the television receiver adjusts the size of a socket buffer associated with a TCP/IP socket and a transmission ring buffer associated with a wireless driver.

Abstract: A system includes a processor and a memory. The memory stores instructions executable by the processor to receive first and second media units with respective first and second time stamps that are assigned based on a first clock cycle time and a data transmission rate, and to assign an adjusted time stamp to the second media unit based on the first clock cycle time, a second clock cycle time, the first time stamp, and the data transmission rate.

Abstract: Various systems, methods and devices are presented for performing media encryption. A media stream comprising video packets can be received. A chunk of the media stream can be sorted to create a first group of a plurality of audio packets with an I-frame header and a second group of a plurality of P-frames and an I-frame payload. The first group can be encrypted while the second group is not encrypted. A fully-protected output media stream that includes the encrypted first group and the second group can then be streamed to a remote device via a network for output.

Abstract: Systems, devices and automated processes are described for improving media streaming in a server device through intelligent selection of initial cache bitrates. The initial cache bitrate is selected with consideration to both historical data and operating parameters of the server device. Operating parameters can include an amount of cache memory that is available on the server device, as well as an amount of reserve space that is desired to be maintained in case of degradation in network performance or other factors that may occur during transcoding or transmission of the media stream.

Abstract: Methods and apparatuses for improving the delivery of streamed audiovisual content derived from over-the-air digital television signals by reducing streaming start latency are described. In response to detecting a request from a client device to begin a streaming session for a video stream captured by an over-the-air antenna, a streaming device in communication with the client device via a wired or wireless networking connection may transmit a reduced resolution version of the video stream to the client device, establish encryption and decryption keys for a secure connection with the client device while the reduced resolution version of the video stream is transmitted to the client device, communicate a point in time after which an encrypted version of the video stream will be transmitted to the client device, and transmit the encrypted version of the video stream to the client device starting at the point in time.
