Streaming media delivery system
Streaming media, such as audio or video files, is sent via the Internet. The media are immediately played on a user's computer. Audio/video data is transmitted from the server under control of a transport mechanism. A server buffer is prefilled with a predetermined amount of the audio/video data. When the transport mechanism causes data to be sent to the user's computer, it is sent more rapidly than it is played out by the user system. The audio/video data in the user buffer accumulates; and interruptions in playback as well as temporary modem delays are avoided.
Scalable media file transfer
Various embodiments of the present application set forth a computer-implemented method comprising determining a set of digital assets to transfer to a destination device, generating, from the set of digital assets, a corresponding set of chunks, where each chunk is a pre-defined size, for each chunk in the set of chunks, transmitting the chunk to a service node included in a set of service nodes, and verifying that the service node received the chunk, where the set of service nodes receives at least two chunks of the set of chunks in parallel, and after the set of service nodes send the at least two chunks in parallel to the destination device, verifying that the destination device received the set of chunks.
Multimedia content delivery with reduced delay
A content delivery server is configured to receive a request for a chunk of a segment of a video stream, the segment of the video stream including a series of chunks, each of the chunks including a set of video frames, a first of the chunks being aligned with a first Instantaneous Decoder Refresh frame in the video stream, and a second of the chunks being aligned with a second subsequent Instantaneous Decoder Refresh frame in the video stream; determine whether the request was received during a first interval or a second subsequent interval of an intra period between the first of the chunks and the second of the chunks; and output the first of the chunks or the second of the chunks for transmission based on the determination of whether the request was received during the first interval or the second interval.
Systems and methods for managing content distribution to an in-transit media system
Systems and methods for dynamically multiplexing requested linear media channels and network data on forward link traffic streams of a communication link to a craft media delivery system are provided. Furthermore, systems and methods for receiving dynamically multiplexed requested linear media channels and network data on forward link traffic streams of a communication link by a craft media delivery system are also provided.
WIRELESS COMMUNICATION APPARATUS, WIRELESS COMMUNICATION METHOD, AND PROGRAM FOR USING A THRESHOLD TO CONTROL MULTICAST RETRANSMISSION
To make it possible to perform retransmission control in which wireless resources are more efficiently utilized, a wireless communication apparatus includes: a wireless communication unit configured to perform wireless communication with a terminal apparatus, a communication control unit configured to control multicast transmission performed by the wireless communication unit; and a setting unit configured to set a threshold for determining whether or not it is necessary for the communication control unit to perform a retransmission process, on the basis of information about reception of a reception acknowledgment response corresponding to the multicast transmission from the terminal apparatus.

Content reproduction device and content reproduction method
A content reproduction device includes a communication unit, a data acquirer, a buffering controller, a buffering condition determiner, a reassembler, and a content reproducer. The communication unit is configured to communicate with an information processing device. The data acquirer is configured to sequentially acquire pieces of data from the information processing device via the communication unit. The buffering controller is configured to buffer the pieces of data in a storage. The buffering condition determiner is configured to determine a buffering condition for buffering the pieces of data, depending on a condition of communication with the information processing device. The reassembler is configured to reassemble the pieces of data buffered in the storage in a predetermined order when the determined buffering condition is satisfied. The content reproducer is configured to reproduce a content based on the reassembled pieces of data.
