At least one legacy rectangular video is captured from an immersive video obtained from a source ( | 2019-04-04 |
20190104331 | DYNAMICALLY PROVIDING DIGITAL CONTENT TO CLIENT DEVICES BY ANALYZING INSERTION POINTS WITHIN A DIGITAL VIDEO - The present disclosure is directed toward systems and methods for dynamically providing digital content to client devices at different insertion points of a digital video based on predicted total value of inserting the digital content and predicted engagement loss of inserting the digital content. For example, system and methods described herein determine that an insertion point is approaching in an actively playing digital video. In response, systems and methods identify digital content for insertion at the insertion point. In one or more embodiments, the described systems and methods insert the identified digital content by comparing the predicted total value of inserting the digital content at the insertion point of the digital video and a predicted engagement loss associated with inserting the digital content at the insertion point of the digital video. | 2019-04-04 |
20190104332 | INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND INFORMATION PROCESSING SYSTEM - The present disclosure relates to an information processing device, an information processing method, and an information processing system capable of appropriately performing scaling of a distribution device which distributes an audio stream encoded by a lossless compression system. An original distribution server performs scaling of a premium server which distributes the audio stream to a premium client on the basis of bit rate information including an average value of a predetermined period of bit rates of the audio stream encoded by a lossless DSD system. The present disclosure is applicable to, for example, the original distribution server or the like. | 2019-04-04 |
20190104333 | Streaming and Storing Video for Audio/Video Recording and Communication Devices - Streaming and storing video for audio/video (A/V) recording and communication devices in accordance with various embodiments of the present disclosure are provided. In one embodiment, a method for an A/V recording and communication device comprises: recording video image data; executing a write operation to write the video image data at a write rate; executing a read operation to read the video image data at a first read rate that is greater than the write rate; continuing to read the video image data at the first read rate until the read operation catches up to the write operation; reading the video image data at a second read rate equal to the write rate; and transmitting streaming video to a client device, wherein a beginning portion of the streaming video is streamed at a first stream rate and thereafter streaming at a second stream rate less than the first stream rate. | 2019-04-04 |
20190104334 | Cable modem with embedded video transmitter - A cable modem with an embedded video transmitter for supporting all-IP end-to-end services in a cable network is disclosed. A cable modem is provided with a video converter/modulator feature. The cable modem receives Internet protocol (IP) packets carrying video streams from a network. A video extractor in the cable modem extracts video packets from the IP packets, and a video modulator in the cable modem modulates the extracted video packets per video format supported by a customer premise equipment (CPE). The cable modem then sends the modulated video packets to the CPE. With this feature, all-IP end-to-end services may be implemented without being dependent on an existing CPE's capability for supporting IP at the customer premises. | 2019-04-04 |
20190104335 | THEATER EARS AUDIO RECOGNITION & SYNCHRONIZATION ALGORITHM - The goal of the audio recognition and synchronization algorithm is to obtain the timestamp (start) of a smaller microphone recorded audio track in a larger (original/unmodified) audio track and to synchronize with the second language track based on the timestamp retrieved. In order to get the position of recorded audio track in original track we first generate a finger print of the original audio track. Next, we run a similar process for the recorded track to generate a second finger print. Given the finger print of the original audio track and the recorded audio track (created above) we can detect the timestamp of the recorded audio track in the original audio track. This is accomplished by matching the frequencies in the finger prints and checking if these frequencies correspond in time. Finally, we apply a detection algorithm to get the timestamp. | 2019-04-04 |
20190104336 | COGNITIVE DIGITAL VIDEO RECORDER - A method for a cognitive digital video recorder (CDVR), where the CDVR determines if it has a capacity is available to accommodate the digital video content and in response to determining that the capacity is not available to accommodate the request, the CDVR receives a user profile data. The CDVR accesses a relationship map and the at least one content tag, wherein the relationship map describes how a plurality of digital content is related to each other. The CDVR performs a cognitive analysis of the user profile data utilizing the accessed relationship map and the at least one content tag and ranks a plurality of digital video content based on the cognitive analysis results. The CDVR deletes an initial at least one of the plurality of digital video content to create the capacity to accommodate the digital video content and stores requested digital video content. | 2019-04-04 |
