Embodiment Construction

[0057] At present, most data filtering rules for digital TV service data packaging and demultiplexing channels follow the secondary filtering standard. That is, at first according to the packet identification (Packet ID, PID) of the data packet to be requested, by the setting of the PID to the demultiplexing channel, the first level of filtering is realized; then according to the table identification (TableID) of the data packet to be requested (the The filtering depth is usually up to 16 bytes), and the second level of filtering is realized by setting the filter associated with the demultiplexing channel. Through the combination of these two filtering methods, a data packet can be uniquely determined from a transport stream (Transport Stream, ST).

[0058] It can be seen that, when performing data filtering, the application needs to successively operate two demultiplexing devices, the demultiplexing channel and the filter, to complete the data filtering task. In order to sim...

Abstract

The invention discloses a digital television receiver and an operation method of demultiplex equipment in a mixed application environment. The method comprises the following steps of: by taking a PID (Proportion Integration Differentiation) parameter of a demultiplex channel as an attribute parameter of a filter, presetting an array for counting the service condition of each filter to form a database taking the filter as an operation management object; and by managing the database, controlling allocation, starting, stopping and releasing methods of the filter and data back transmission and realizing the shared use operation of the demultiplex equipment in the mixed environment in which DVB (Digital Video Broadcasting) base application and an intermediate piece system coexist. According tothe invention, the problem of the PID of the demultiplex equipment in the mixed environment can be solved; and the higher switching speed and the high-efficiency data back transmission can be realized.

Description

technical field [0001] The present invention relates to demultiplexing control in digital television receiving process, in particular to an operation method of demultiplexing equipment in a mixed application environment, and a digital television receiver using the operation method. Background technique [0002] At present, with the promotion and development of digital TV technology, the market demand for digital TV value-added services is expanding, and third-party middleware services such as browsers, stock systems, and online games are very popular among users. At present, the DVB basic applications of third-party middleware and set-top box manufacturers mostly run in the digital TV receiver in the form of co-existence. Users request to switch between the two through keystrokes, and the middleware system and DVB basic applications share the digital TV receiver. The resources are used to complete their respective tasks, thus forming a mixed application environment in which ...
