  • Patent number: 10111195
    Abstract: A method implemented in Access Nodes (ANs) for maintaining synchronization in a radio access network employing a hierarchical synchronization mechanism. One of the methods is implemented in an Access Node (AN) at synchronization level 1 and comprises detecting that an AN at synchronization level 0 is down and initiating a random back-off procedure. The method further comprises determining whether a first synchronization signal generated at another AN at synchronization level 1 is received during the random back-off procedure. If it is determined that no first synchronization signal is received during the random back-off procedure, a second synchronization signal providing a synchronization reference is generated and broadcast upon completion of the random back-off procedure. The method also provides ANs for maintaining synchronization in a radio access network employing a hierarchical synchronization mechanism.

  • Patent number: 9973562
    Abstract: Techniques are described for split processing of streaming segments in which processing operations are split between a source component and a decoder component. For example, the source component can perform operations for receiving a streaming segment, demultiplexing the streaming segment to separate a video content bit stream, scanning the video content bit stream to find a location at which decoding can begin (e.g., scanning up to a first decodable I-picture, for which header parameter sets are available for decoding), and send the video content bit stream to the decoder component beginning at the location (e.g., the first decodable I-picture). The decoder component can begin decoding at the identified location (e.g., the first decodable I-picture). The decoder component can also discard subsequent pictures that reference a reference picture not present in the video content bit stream (e.g., when decoding starts with a new streaming segment).

A BS being in isolation starts a wireless communication with a CPE, connected to the internet, so as to access a database to acquire a list of frequencies available for transmission. The BS uses a predetermined frequency to perform the wireless communication with the CPE, and acquires, via this wireless communication, the list of frequencies available for transmission. Thereafter, the BS performs wireless communications with the CPE and with another CPE on the basis of the acquired list of frequencies available for transmission. The BS can hold, in advance, information of the predetermined frequency for which it has been estimated that the BS will cause no interference with the wireless communications of the primary users.

  • Patent number: 9456186
    Abstract: Various arrangements for presenting an electronic programming guide are detailed. An indication of a first television channel for tuning may be received by a television receiver. The first television channel may be transmitted as part of a first transponder stream. Based on an inadequate downlink signal being received for the first television channel, it may be determined that the first television channel cannot be received and output. A plurality of unavailable television channels may be identified due to the plurality of unavailable television channels being transmitted as part of the first transponder stream. An electronic programming guide may be output to a display device that indicates the plurality of unavailable television channels and the first television channel are each unavailable.
