20140105310 | APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING PACKET IN A BROADCASTING AND COMMUNICATION SYSTEM - A method of transmitting a complex content packet in a broadcasting and communication system is provided. The method includes creating an Forward Error Correction (FEC) source block by using at least one MMT Processing Unit (MPU) included in at least one MPEG Media Transport (MMT) asset, and transmitting the FEC source block, wherein the FEC source block is generated so that a boundary of the at least one MPU and a boundary of the FEC source block do not deviate. | 2014-04-17 |
20140105311 | NON-INTERRUPTIVE FILTERING OF TRANSMISSION LINE COMMUNICATIONS - Systems and methods according to aspects of the subject technology provide non-interruptive filtering of transmission line communications. The non-interruptive filtering may physically isolate, in the frequency domain, independent networks that share a common transmission media, such as mains wires that are used to deliver both alternating current (AC) power and power line communication signals. The isolation provided by the non-interruptive filtering prevents the transmissions from the independent networks from interfering with each other. In one or more implementations, the non-interruptive filtering may be provided by one or more filters that include cores, such as ferrite cores, around which two mains wires, e.g. a mains live wire and a mains neutral wire, can be wound in opposite directions, respectively. Currents traveling on the mains wires through the filter in opposite phases cancel each other out, thereby blocking symmetric power line transmissions, while allowing AC power to pass through. | 2014-04-17 |
