20200119823 | RECEPTION DEVICE, TRANSMISSION DEVICE, AND DATA PROCESSING METHOD - Provided are a device and a method which are capable of realizing an efficient search of metadata such as access information corresponding to acquisition-scheduled data in a reception device. A reception device receives a token which is auxiliary search information for efficiently searching for metadata such as access information related to acquisition-scheduled data of the reception device and performs a search process using the token. The token includes a service worker (SW) search scope token capable of limiting a search scope of access information corresponding to data serving as a management target of a specific service worker (SW) which is a data management program and a service worker (SW) cache scope token indicating that access information corresponding to data serving as a management target of a service worker (SW) is collectively recorded. | 2020-04-16 |
20200119824 | SOURCE IDENTIFICATION USING PARALLEL ACCUMULATION AND COMPARISON OF BROADCAST FINGERPRINTS - First fingerprint data is accumulated in a first fingerprint buffer of a channel identification server in parallel with accumulation of second fingerprint data in a second fingerprint buffer of the channel identification server. The first and second fingerprint data include multiple fingerprints representing broadcast content broadcast by corresponding broadcast sources during contiguous time periods, and accumulating the fingerprints includes appending newly received first fingerprints to previously received first fingerprints to generate continuous fingerprints. The channel identification server also receives an unmatched fingerprint representing broadcast content received from an unknown broadcast source by the end-user device. The unmatched fingerprint into probes, which are scrubbed against both first and second continuous fingerprints in an attempt to determine a match between the unmatched fingerprint and either the first or second continuous fingerprint. The unknown broadcast source is identified based on that determination. | 2020-04-16 |
20200119825 | CLOCK SYNCHRONIZATION OVER A WIRELESS CONNECTION - Techniques for clock synchronization over a wireless connection are provided. A first wireless node determines an offset between a first clock used by the first wireless node for a wired connection between the first wireless node and at least one upstream node and a second clock used by the first wireless node for a wireless connection between the first wireless node and a second wireless node on the downstream. The first wireless node transmits an indication of the determined offset to the second wireless node for use by the second wireless node to calibrate a third clock corresponding to the first clock to synchronize the third clock with the first clock, wherein the third clock is used by the second wireless node for a second wired connection with at least one downstream node. | 2020-04-16 |
20200119826 | TIMING SYNCHRONIZATION OVER CABLE NETWORKS - In one embodiment, a method receives a first time from a network device. The first time is derived from a first timing source in a first domain. The method receives a second time in a second domain from a second timing source. A difference time value is calculated between the first time and the second time. The method then sends the difference time value to the network device where the network device uses the difference time value to send a delay value to other computing devices to synchronize timing of the other computing devices in the second domain. The other computing devices are configured to synchronize the respective time using the delay value with mobile network devices to allow timing synchronization between the mobile network devices. | 2020-04-16 |
20200119827 | Methods and Systems for OFDM Using Code Division Multiplexing - In some embodiments of the invention, OFDM symbols are transmitted as a plurality of clusters. A cluster includes a plurality of OFDM sub-carriers in frequency, over a plurality of OFDM symbol durations in time. Each cluster includes data as well as pilot information as a reference signal for channel estimation. In some embodiments, a plurality of clusters collectively occupy the available sub-carrier set in the frequency domain that is used for transmission. In some embodiments of the invention data and/or pilots are spread within each cluster using code division multiplexing (CDM). In some embodiments pilots and data are separated by distributing data on a particular number of the plurality of OFDM symbol durations and pilots on a remainder of the OFDM symbol durations. CDM spreading can be performed in time and/or frequency directions. | 2020-04-16 |
