Abstract: Aspects are related to reducing size of diagnostic data downloads. To reduce the size, format and content are read from a diagnostic data file so that pre-defined priority rules may be applied to the diagnostic data file and/or a subset of the diagnostic data file utilizing the format or the content. Then, a priority level is assigned to the diagnostic data file or the subset based on an ability of that file or that subset to diagnose a failure as determined by the pre-defined priority rules. Next, an ordering of the diagnostic data file and/or the subset into a file stream occurs, followed by a streaming of the file stream to a remote diagnostic system. A notification can be received from the remote diagnostic system to stop the streaming if sufficient diagnostic data to diagnose the failure has been received by the remote diagnostic system.

Abstract: 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.

The method also includes transmitting the playlist and each of the segment files to a cache server, obtaining the video broadcast stream as a series of frames, and transmitting each frame in the series of frames to the cache server using an HTTP chunk transfer protocol, each frame being associated with, and written to, a first segment file identified in the playlist. When a frame in the broadcast stream is a break frame, the method includes transmitting an end of file marker for the first segment file and adding a video header for the break frame before it is transmitted.

Abstract: Systems and methods for identifying, assembling, and publishing content are described. A content item, such as a video, having a first time length, is identified by a system to be included in a program scheduled for a first time period. The video may be hosted on a third party system.

The system determines, prior to or at the first time period, a time difference between a current length of the video and the first span of time. At least partly in response to determining that the video has a time length shorter than the first span of time, the system selects supplemental content based at least in part of the determined time difference to be streamed to user terminals over a data network within the first time period.

Abstract: User equipments can download a video file by instantiating multiple video requests, each request specifying different parts of the video file. If each video request initiates a separate transmission control protocol (TCP) session, which is the case with an hypertext transfer protocol (HTTP) partial get request, then a network device in a communications network would be oblivious of contextual information, which indicates that the TCP sessions download different portions of the same video file. This disclosure provides systems and methods for correlating multiple TCP sessions so that a network device in a communications network can be aware of the contextual information.
