20090327676 | DEMODULATOR DEVICE AND METHOD OF OPERATING THE SAME - A demodulator device and a method of operating the demodulator device where the demodulator device runs a loaded operating system and operates a communication protocol enabling a host application to control the demodulator device. The demodulator device is configured to respond to receipt of an abort command of the communication protocol by carrying out an abort process which stops current operations and reinitializes the loaded operating system. | 12-31-2009 |
20090293072 | SYSTEM HAVING PLURALITY OF HARDWARE BLOCKS AND METHOD OF OPERATING THE SAME - A system having a plurality of hardware blocks and a method of operating that system where power to each hardware block is independently controlled according to whether or not the respective hardware block is needed for use. A counter is provided in the respective device driver of each hardware block, the counter being configured to be incremented each time a task requests use of the respective hardware block and to be decremented each time a task ceases use of the respective hardware block. The value of the counter is used to control whether or not to power up or power down the respective hardware block. | 11-26-2009 |
20090037948 | MULTICAST TELEVISION SYSTEM - A multicast television system including a server device and a plurality of user devices wherein a stream of data including television program data and advertisement data is multicast by the server device for reproduction by a plurality of user devices wherein, in the multicast stream of data, a period of advertisement data is provided together with marker data, the marker data indicating the length of the period. At individual respective user devices receiving the multicast stream of data, advertisement data stored locally at the respective user devices is selectively reproduced in place of the period of advertisement data provided in the multicast stream of data. | 02-05-2009 |
20080282300 | DIGITAL TELEVISION RECEIVER - A digital television receiver for use in a digital television broadcast system in which a plurality of digital television data streams can be provided in respective streams of television broadcast packets forming the lowest layer of a layered digital television structure and also in respective streams of Internet protocol packets forming the lowest layer of a layered Internet protocol structure, at least the streams of television broadcast packets being broadcast with a plurality of tables indicating where data of one layer of one structure can be found in another layer of one or other of the two structures, the received plurality of tables being used to determine where data contained in one layer can be found in an adjacent layer so as to construct tree structures or a new table allowing determination of in which stream of television broadcast packets the television data of a selected stream of Internet protocol packets is found. A two-stage process for identifying an alternative stream with television broadcast packets containing the same television programme is also proposed in which, first, identical transport streams are looked for and, second, the stream of Internet protocol packets containing the television programme are used to identify alternative streams of television broadcast packets containing the same television programme. | 11-13-2008 |
