Abstract: Techniques are provided for reducing delay during streaming transmissions. For example, a method may include receiving a stream of data segments. The method may include establishing a first group of segments based on the data segments, and generating a first table of information. The method may include transmitting the first table and the first group of segments, and establishing a second group of segments based on the data segments, the second group of segments including a partial overlap of data segments included in the first group of segments. The method may include generating a second table of information, and transmitting the second table and a collection of segments that includes data segments from the second group that were not part of the first group.

Abstract: In general, this disclosure relates to techniques for switching between media broadcast streams having varying levels of quality. In one example method, a processing pipeline of a communication device processes a first broadcast stream representing a first version of media content. The processing pipeline includes quality checkpoints at which broadcast stream quality may be determined, and receives a second, different broadcast stream that is broadcasted at another data rate. The second broadcast stream represents a second version of the media content of different media quality. The processing pipeline measures a quality of the first broadcast stream and a quality of the second broadcast stream at one or more of the quality checkpoints, and switches the processing from the first broadcast stream to the second broadcast stream if the quality of the second broadcast stream exceeds a defined threshold at one or more of the quality checkpoints.
