Abstract: Systems and methods are described for load balancing between a set of servers. Subsets of servers from the set of servers are assigned, via deterministic subsetting, to respective clients from a set of clients. Unlike conventional load balancing techniques using deterministic subsetting, the disclosed techniques enable configuring a client to distribute different amounts of load among the servers in its server subset. Techniques for constructing the subsets are also described.

Abstract: A messaging system automatically populates a stream of messages using only a seed selected by the requesting account holder. In one embodiment, the seed includes the streams of one or more of the “top” accounts of the messaging system. Here, “top” is according to any one of a number of different metrics stored in the messaging system. With knowledge of the seed, the messaging system automatically populates a stream for the requesting account holder, without requiring any other input. As a result, an account holder is provided with a fully functioning stream with very little effort or knowledge required on their part.

Abstract: Implementations provide a structure for low-latency live-video streams using existing content delivery networks. An example method includes creating, at the start of a broadcast stream, a playlist for the broadcast stream that identifies at least two segment files.

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: A system is described that receives first user identifiers from a first user space and a first set of hash values generated from a hash function applied to first information that identify users associated with the set of first user identifiers. The system determines a hash value included in both of the first set of hash values and a second set of hash values that are generated from the hash function being applied to second information that identify users associated with second user identifiers from a second user space. The system generates a mapping between the first user identifiers and the second user identifiers that each correspond to the same hash value. The system determines targeted information directed to the first user identifiers and based on the mapping, outputs the targeted information to user devices associated with the second user identifiers.

Abstract: A real time messaging platform identifies an audio snippet of a time-based media (TBM) event. The messaging platform maintains a real time repository of concurrently broadcasting TBM events as well as a historical repository of previously broadcast TBM events. These repositories contain acoustic fingerprints of their respective TBM events. The messaging platform matches an acoustic fingerprint of the audio snippet with one of the stored acoustic fingerprints to identify the TBM event in the recorded snippet. To identify the TBM event, the messaging platform matches multiple overlapping reference audio segments of the reference audio stream with multiple test audio segments of the audio snippet. This allows the platform to account for time delays between the test and reference audio segments that would otherwise hinder the matching process.

Abstract: Techniques of playing back a looping video file involve providing multiple video codecs for decoding a video file. Each video codec performs its own decoding operation on the looping video file, resulting in multiple buffers of video frames and a buffer of audio frames. Then, as the GPU renders the ending video frames from a first buffer, it begins rendering the beginning video frames from a second buffer. In this way, the beginning of a next video cycle is already rendered for viewing by the time a current video cycle is ending.

Abstract: Images of key phrases or hashtags appear on televised feeds. Image processing techniques, such as feature locating algorithms or character recognition algorithms, can be used to locate the images of key phrases in the images. Then, character recognition algorithms can be used to generate a list of candidate key phrases for the key phrase in image format. However, identification of the key phrase in image format is not completely accurate with conventional methods. Social media content items associated with the televised feed are used to filter the list of candidate key phrases. Using known information about the televised feed as well as about key phrases in text format in the social media content items, candidate key phrases in the list of candidate key phrases can be scored and, thus, a final candidate key phrase selected based on the scores.
