Abstract: Techniques are described for synchronous capture and playback of 4D content. A 4D synchronous capture system retrieves sensor readings that describe environmental parameters at a point of time at which the sensor readings have been captured. Based the sensor readings, the system generates 4D content data, which digitally represents the environmental parameters captured by sensor readings. The system synchronizes the 4D content data with concurrently captured audio-visual content data and causes the concurrently captured 4D content data and the audio-visual content data to be associated with the same timing information. Based on the time synchronization, the 4D content data reproduces the environmental parameters in synch with the playback of the audio-visual content, in an embodiment.

Abstract: A system and method for effectuating channel changes in a multicast adaptive bitrate (MABR) streaming network using a dedicated bandwidth pipe for downloading a requested channel's data in a recovery segment by issuing an HTTP request. A video management agent is configured to stitch the recovery segment's data with the regular channel stream during the channel change to generate a hybrid stream, which is multicast streamed toward the requesting device. Once the data from the regular channel stream is properly joined, recovery segment downloading ceases and the bandwidth consumed for sending recovery data in the dedicated bandwidth pipe is released.
