Currently, demultiplexing of a TS stream is done by two demultiplexers: one demultiplexer is responsible for filtering out the TS Stream of the current channel from the synthesized TS Stream, and the TS Stream of the current channel is usually a scrambled TS Stream, so that the TS Stream needs to be sent to a conditional access module for descrambling, and the descrambled TS Stream is sent to another demultiplexer to filter out the ES Stream (Elementary Stream) of the audio and video of the current channel, and then the ES Stream is decoded by a decoder for playing. The above processing procedure uses two demultiplexers, occupying more demultiplexer resources.

The embodiment of the invention provides a method for demultiplexing a TS stream, which completes demultiplexing processing on the TS stream by using a single demultiplexer. Referring to fig. 1, a schematic diagram of a television set according to an embodiment of the present invention is shown. The television set includes: a demultiplexer 110, a conditional access module 120, a decoder 130, a USB (Universal Serial Bus) controller 140, a tuner 150, a demodulator 160, a processor 170, a remote controller 180, and a display 190.
The conditional access module 120 is a conditional access module (i.e. USB CAM) based on a USB interface, and transmits data based on a USB protocol under the control of a USB controller, which of course, the present invention does not specifically limit the interface type of the conditional access module, and conditional access modules of other interface types can also implement the technical solution of the present invention under the support of the corresponding interface protocol.
In addition, the modules within the dashed box shown in fig. 1 are usually integrated into the same main chip of the television, so as to reduce the cost and improve the reliability. However, the present invention does not limit whether these modules are integrated on the same chip, and each module independent of each other can also implement the technical solution of the present invention.
Referring to fig. 2, a flow chart of an embodiment of the method for demultiplexing a TS stream according to the present invention is shown, and the embodiment describes a process of demultiplexing a TS stream from the demultiplexer 110 side.
Step 201, when a first TS stream is received from a first input port, filtering a second TS stream corresponding to a current channel from the first TS stream containing multi-channel audio-video data, and outputting the second TS stream from a first output port.
As shown in fig. 1, after the radio frequency signal is tuned and demodulated by the tuner 150 and the demodulator 160, a first TS stream is output, which includes audio and video data of a plurality of channels and is output to the demultiplexer 110 in the form of a plurality of consecutive data packets (packets).
The demultiplexer 110 receives the first TS stream from the first input port (e.g., the P1 port shown in fig. 1), and before filtering out the second TS stream corresponding to the current channel (the channel is selected by the remote controller 180) from the first TS stream, needs to configure a binding relationship between the first input port and the first filter for filtering out the second TS stream from the first TS stream. The specific process of filtering out the second TS stream from the first TS stream by the demultiplexer 110 is to filter the first TS stream containing the multi-channel audio/video data received from the first input port by using the first filter bound to the first input port, and filter out the second TS stream corresponding to the current channel.
Wherein the first filter includes a control filter and a data filter, and the second TS stream includes control information data packets and data information data packets of the current channel. The Specific process of filtering the first TS stream by the demultiplexer 110 using the first filter is to filter the first TS stream containing multi-channel audio/video data received from the first input port by using a control filter included in the first filter bound to the first input port, and filter out a control Information packet corresponding to the current channel, for example, a PSI (Program Specific Information) packet, where an effective load of the PSI packet carries detailed Information of a Program, such as a Program table, network Information, and the like; the first TS stream containing multi-channel audio/video data received from the first input port is filtered by using a data filter included in the first filter bound to the first input port, and a data information packet corresponding to the current channel, for example, a PES (Packetized elementary stream) packet is filtered, and a payload of the PES packet carries program specific contents such as video, audio, and subtitles.
The filter filters out data packets (packet headers of the data packets carry PID values) in the TS stream that are different from PID (packet identifier) values of audio and video of the selected channel, and only retains the data packets of the selected channel, that is, the TS stream of the selected channel. The filtering principle is prior art and will not be described herein.
The second TS stream filtered by the demultiplexer 110 is usually a scrambled TS stream, and needs to be output to the conditional access module 120 for descrambling. The demultiplexer 110 needs to configure a binding relationship of the first filter and the first output port before outputting the second TS stream to the conditional access module 120 through the first output port (e.g., the P2 port shown in fig. 1) connected to the conditional access module 120. The specific process of the demultiplexer 110 outputting the second TS stream from the first output port is to output the second TS stream filtered by the first filter from the first output port bound to the first filter, so that the conditional access module 120 connected to the first output port descrambles the second TS stream to obtain a third TS stream, and returns the third TS stream to the demultiplexer 110.
And 202, when the third TS stream is received from the second input port, filtering out an ES stream of the audio and video of the current channel from the third TS stream, and outputting the ES stream from the second output port.
The demultiplexer 110 receives the third TS stream from the second input port (e.g., the P3 port shown in fig. 1), and the demultiplexer 110 needs to configure the binding relationship between the second input port and the second filter for filtering out the ES stream from the third TS stream before filtering out the ES stream of the audio/video of the current channel from the third TS stream. The specific process of filtering, by the demultiplexer 110, the ES stream of the audio and video of the current channel from the third TS stream is to filter, by using a second filter bound to the second input port, the third TS stream received from the second input port, and filter the ES stream of the audio and video of the current channel. The ES stream is no longer in the form of packets, but is a continuous audio-video stream that follows a certain coding format, for example, an MPEG-2(Moving Picture expert group-2, version 2 of the motion Picture experts group) format.
The demultiplexer 110 needs to output the filtered ES stream to the decoder 130 for decoding. Before outputting the ES stream to the decoder 130 through a second output port (e.g., a P4 port shown in fig. 1) connected to the decoder 130, a binding relationship between a second filter and the second output port needs to be configured. The specific process of the demultiplexer 110 outputting the ES stream from the second output port is to output the ES stream filtered by the second filter from the second output port bound to the second filter, so that the decoder 130 connected to the second output port decodes the ES stream to obtain an audio/video stream for playing, and outputs the audio/video stream to the display 190 for playing.
It can be seen from the above description that the present invention utilizes a single demultiplexer to implement demultiplexing on channel audio and video, which saves the resources of the demultiplexer, and especially when only one demultiplexer is provided in the system (for example, only one demultiplexer is provided in the main chip of the television), the demultiplexing method of the present invention can still implement demultiplexing on channel audio and video.
The process of TS stream demultiplexing will now be described in detail by taking the television shown in fig. 1 as an example.
After the radio frequency signal is modulated and demodulated by the tuner 150 and the demodulator 160, a TS stream containing audio and video data of a plurality of channels is output and recorded as TS 1.
After receiving the TS1 through the P1 port, the demultiplexer 110 filters a TS stream corresponding to the current channel selected by the user (the channel selected by the user through the remote controller 180) from the TS1, which is denoted as TS2, and the TS2 is a scrambled TS stream, by using a preconfigured Filter bound to the input port P1, which is denoted as Filter 1. The demultiplexer 110 outputs the TS2 to the USB controller 140 by using the output port P2 bound to the Filter1, and the USB controller 140 transmits the TS2 to the conditional access module 120 based on the USB interface.
After the conditional access module 120 descrambles the TS2, the descrambled TS stream is output, which is denoted as TS3, and the TS3 is returned to the demultiplexer 110 via the USB controller 140.
After receiving the TS3 through the P3 port, the demultiplexer 110 uses a pre-configured Filter bound to the input port P3 to mark as Filter2, and filters out an ES stream of an audio/video of a current channel from the TS3 to mark as ES1, where the ES1 is an encoded audio/video stream. The demultiplexer 110 outputs ES1 to the decoder 130 using the output port P4 bound to the Filter 2.
The decoder 130 decodes the ES1 and outputs the decoded ES1 to the display 190 for playback.
The invention also provides an embodiment of a television corresponding to the embodiment of the method for demultiplexing the TS stream.
