In order to make real time and the avoidance of risk compatible according to the contents of processing by an application, an index ID applying module applies an index computed utilizing streams before and after stream data to the stream data, computes the index again according to a stream that varies every moment, applies an index computed based upon the index of the stream data to the result of the processing of the stream data according to a predetermined procedure and outputs it. An application that receives the result of the processing and the index of the result of the processing switches processing depending upon the index.
摘要:
To provide, in a multimedia content server which stores multimedia data and transmits the stored multimedia data to a terminal, a technique which allows the terminal to implement a data broadcast even when random access for trick play, and the like, is performed. Upon receiving a data transmission request from a multimedia data receiving apparatus, a multimedia data transmitting apparatus transmits the requested multimedia data and definitely inserts data required for data broadcasting or transmits data for data broadcasting, separately from the multimedia data, thereby enabling the multimedia data receiving apparatus to obtain the data required for data broadcasting.

An ink jet recording method includes the steps of providing an ink jet recording head having a plurality of discharge openings for discharging ink, a plurality of liquid passageways for holding ink and a plurality of heat generating members. Each of the heat generating members corresponds to a liquid passageway and each heat generating member has a pair of electrodes for driving the heat generating member individually and the electrodes and corresponding heat generating member form a U-shaped wiring portion. The recording head may be manufactured using a cutting process. A voltage is applied to selected pairs of electrodes for driving selected heat generating members individually for providing thermal energy to the ink in the liquid passageway for abruptly forming a bubble and discharging ink from the discharge opening and recording on a recording medium.
摘要:
A broadcast signal receiving apparatus receives a plurality of transport streams and uses conditional access provided by an external adapter. The broadcast signal receiving apparatus includes a pre-processor operable to extract a part of information, by elementary stream unit, from each of the plurality of transport streams by receiving a filtering condition from the external adapter and performing filtering on the plurality of transport streams according to the filtering condition. The broadcast signal receiving apparatus also includes a multiplexer, an output interface, an input interface, and a demultiplexer. The external adapter is detachable from the broadcast signal receiving apparatus, and includes a conditional access descrambler that descrambles transport stream packets in the multiplexed data that are protected by conditional access with a packet identifier specified by the controller in the broadcast signal receiving apparatus.
