With the continuous development of related technologies, the application of speech recognition technology to electronic devices has achieved preliminary results.

Digital TV can watch more and more TV programs, and the network video programs that can be ordered through digital TV are becoming more and more abundant. Overseas digital TV programs include terrestrial cable signal Digital Video Broadcasting (Digital Video Broadcasting-Cable, DVB-C), terrestrial wireless signal (Digital Video Broadcasting-Terrestrial, DVB-T) and multiple satellites (Digital Video Broadcasting-Satellite, DVB- S) Signals, as many as tens of thousands of TV programs; online video programs also come from multiple service providers, such as YouTube, PrimeVideo or Netflix. It is very necessary for users to obtain the target programs they want to watch from the massive TV program list and numerous network video programs.

The way for users to find TV programs is to search by opening one by one. The operation process is: if the user wants to watch the SBS program of the terrestrial cable signal DVB-C, the user needs to switch the TV program channel of the digital TV to DVB-C through the remote control , And then look for TV programs in the TV program list of DVB-C. The problem with this search method is that users may not know whether the TV program they want to search is in DVB-T, DVB-C or DVB-S, so each channel needs to be searched once.

detailed description

The following describes specific embodiments of the present application with reference to the drawings. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limit the present application.

Example one

FIG. 1 is a flowchart of a program search method provided by an embodiment of the present application. This embodiment can be applied to a case where an intelligent search is performed on TV programs under different program channels of a digital TV and network video programs provided by different service providers. The method may be executed by a program search device, which is implemented by software and/or hardware, and is configured on an electronic device. For example, the electronic device may be a digital TV or a set-top box. In this embodiment, the electronic device is used as A digital TV is used as an example for description. Referring to FIG. 1, the program search method includes the following steps.

S110. Receive a program search request input through voice.

With the development of voice technology, more and more devices support voice input. In an embodiment, the program search request input by the user through voice can be received through a microphone (MIC) of the voice remote control, and the program search request input by user through the voice can also be received through the voice collection module in the smart speaker. Of course, In this case, smart speakers need to be connected to the digital TV. Whether it is a voice remote control or a smart speaker with a voice collection function, it is usually integrated with a voice collection device such as Baidu Genie or Amazon's echo to realize the voice collection function.

The program search request is, for example: "I want to watch the happy base camp of Hunan Satellite TV", "I want to watch the movie channel", "I want to watch the movie starring Tong Da" or "I want to watch the terrestrial cable signal DVB-C program SBS "Wait. When the program search request clearly states that the user currently wants to watch a certain TV, a TV station, a channel or a channel (DVB-T, DVB-C or DVB-S), it is considered that the user currently wants to watch the target program The attribute information is a TV program. If the program search request does not clearly state that the user currently wants to watch a certain TV, a TV station, a channel, or a channel, the attribute information of the target program that the user currently wants to watch is considered to be an online video program. Programs whose attribute information is TV programs refer to programs of different channels received through channels DVB-T, DVB-C, or DVB-S, for example, real-time broadcast programs of TV programs such as "Hunan Satellite TV" and "Zhejiang Satellite TV" are TV programs; attributes The information refers to the online video program, which refers to the video programs that can be ordered on demand at any time provided by different service providers (such as YouTube, PrimeVideo, Amazon Video, or Netflix, etc.), such as: The Happy Base Camp in the past, the "Zhen Huan Chuan", "" "Complete Yanxi Raiders" and other complete video resources.

S120. Perform speech recognition on the program search request to obtain program search keywords.

In this embodiment, the essence of voice collection is the process of converting an analog signal into a digital signal. The voice remote control usually does not have a voice recognition function, so the voice remote control needs to upload the collected voice signal to a device with a voice recognition function for voice Identify. In an embodiment, the program search request input by the user through voice is picked up by the MIC of the voice remote control, and then the picked up voice program search request is converted into analog/digital (Analog/Digital, A/D) to obtain the corresponding pcm file , And upload the pcm file to the cloud platform, that is, Amazon Cloud Computing Services (Amazon Web Services, AWS) cloud server, and the AWS cloud server performs voice recognition based on the pcm file to obtain text keywords corresponding to the voice program search request, The text keyword is returned to the digital TV terminal, and the text keyword is the program search keyword.

S130. Determine attribute information of the target program according to the program search keyword.

In this embodiment, the attribute information of the target program includes: a TV program or a network video program. The attribute information of the target program can be determined according to the matching similarity by matching the program search keyword with the preset keyword.

The search sequence number of each TV program refers to the sequence number that the TV program is searched for, and the search sequence number is sequentially increased from 1, and the search sequence number is increased by 1 every time a TV program is searched. In this embodiment, the identification number corresponding to the TV program is arranged using 16-bit binary data, wherein the upper three digits, that is, the first three digits from the left are the program channel type labels, which are used to identify the program channel where each TV program is located. For example, the upper three digits are 000, indicating that the program channel is DVB-S, and the remaining 13 bits are arranged starting from 1 according to the search sequence number of the program searched under the channel DVB-S, and increasing in sequence. Therefore, the TV under the channel DVB-S The range of the program's identification number is; 000 000 000 000 000 000-000 11111 1111 1111. The upper three digits are 001, indicating that the program channel is DVB-T, and the range of the identification number of the TV program under the channel DVB-T is; 001, 000, 000, 0000, 0000, 001, 11111, 1111, 1111; the upper three digits are 010, indicating that the program channel is DVB-C , The range of the identification number of the TV program under the channel DVB-C is: 010 00000 0000 0000-010 11111 1111 1111.

Analyze the identification number to obtain the program channel corresponding to the target program, specifically, to obtain the numerical value of the upper three digits of the identification number corresponding to the target program. When the program channel corresponding to the target program is acquired, the digital TV is automatically switched to the program channel corresponding to the target program to play the target program, thereby achieving automatic switching of the program channel and convenient search and playback of the target program. The user does not need to care about the program channel where the target program is located, but only needs to know the name of the target program to realize the viewing of the target program. At the same time, in order to facilitate user operation and avoid calling the digital TV input method manually to input the viewing request through the remote control, this embodiment proposes to enable the user to input the viewing request in the form of voice, that is, the program search request, based on the program search request input by the user through voice, Directly automatically jump to the corresponding program channel to play the target program, greatly improving the user experience
