For example, the television set includes: tuner, demultiplexing device, player, image rendering device, image output device, audio output device, and other various types of sub-devices.
By executing the television control method provided by each embodiment of the invention, each device required for transmitting the service data corresponding to the information source can be determined from each sub-device included in the television, and the connection path between each device is established, so that the transmission of the service data corresponding to the information source is realized, the devices required for the service data corresponding to the information source can be more flexible, the utilization rate of each device in the television is improved, and the types of the information sources supported by the television and the types of the multimedia services of the realized information sources can be effectively improved.
The embodiment of the invention provides a television control method. The television control method can be realized by a processor integrated in a television through software and/or hardware. The devices mentioned in the following embodiments of the present invention may be sub-devices included in a television. Fig. 1 is a flowchart of a television control method according to an embodiment of the present invention. As shown in fig. 1, the method may include:
s101, determining first equipment for sending service data corresponding to the source.
Specifically, the source may be any one of the following: DTV information source, PVR information source, HDMI information source and the like. The S101 may be performed before transmitting the service data corresponding to the source. For example, in S101, after receiving the service request corresponding to the source or the service data corresponding to the source, the first device that transmits the service data corresponding to the source may be determined. The service request corresponding to the source or the service data corresponding to the source may be sent by an application module corresponding to the source in the television, for example. The television control method may be performed by a processor through a scheduling module.
The first device may be a source input device corresponding to the source in the television, or may be an intermediate input device directly or indirectly connected to the source input device in the television. If the first device is a source input device corresponding to the information source, in S101, the source input device corresponding to the information source may be determined according to the identifier of the information source and a preset corresponding relationship between the information source and the source input device. If the first device is an intermediate input device corresponding to the source, the intermediate input device corresponding to the source determined in a manner similar to the determination of the second device described below may also be used in S101.
And S102, when the first device is an input device, selecting one device from at least one output device corresponding to the first device as a second device for receiving the service data corresponding to the information source.
Optionally, when the first device is an input device in S102, before selecting one device from at least one output device corresponding to the first device as a second device for receiving the service data corresponding to the source, the method may further include:
and determining a selector corresponding to the first device, and determining at least one output device corresponding to the first device according to the selector corresponding to the first device. The selector corresponding to the first device may include: information of the first device as an input device, and information of at least one output device corresponding to the first device.
The selector corresponding to the first device may be determined from selectors corresponding to multiple types of devices according to the type of the first device. The selector corresponding to one type of device may be implemented by a program, an integrated circuit, or a combination of an integrated circuit and a program code. The selector corresponding to the first device may be a selector of a type of the first device. That is, the selector corresponding to the first device may further include other devices of the same type as the first device. The first device may be an input device of each output device corresponding to the first device, and each output device corresponding to the first device may also be an output device of the first device, so as to transmit the service data from the first device to each device.
The selected one of the at least one output device corresponding to the first device may receive the service data corresponding to the source sent by the first device as the second device.
It should be noted that, after the first device that transmits the service data corresponding to the information source and the second device that receives the service data corresponding to the information source are determined, the link corresponding to the information source is successfully created.
If the at least one output device corresponding to the first device is unavailable to the first device, the link creation corresponding to the information source fails according to the fact that the first device cannot determine a second device receiving the service data corresponding to the information source from the at least one output device corresponding to the first device.

Specifically, in the method, the output end of the first device may be connected to the input end of the second device, that is, the output target of the first device is set to the second device, or the signal input source of the second device is set to the first device, and a physical connection between the first device and the second device is established, so as to establish a connection path from the first device to the second device. The connection path between the first device and the second device is actually used for transmitting the service data corresponding to the source, and therefore, the connection path between the first device and the second device is actually a transmission path of the service data corresponding to the source.
The television control method provided by the embodiment of the invention determines a first device for sending service data corresponding to an information source, selects one device from at least one output device corresponding to the first device as a second device for receiving the service data corresponding to the information source when the first device is an input device, and establishes a connection path between the first device and the second device so as to transmit the service data corresponding to the information source from the first device to the second device, thereby realizing the transmission of the service data corresponding to the information source, enabling the devices required by the service data corresponding to the information source to be flexible, improving the utilization rate of each device in the television, and effectively improving the types of the information sources supported by the television and the types of multimedia services of the realized information sources.
Optionally, the second embodiment of the present invention further provides a television control method.

Specifically, in S201, the selectors corresponding to the multiple types of devices on the selector chain table of the television may be sequentially traversed according to the information of the first device, and whether the input device information of the selector corresponding to each type includes the information of the first device is respectively determined. When the input device information of the selector corresponding to the type-A devices in the multiple types does not include the information of the first device, the type-A device is unavailable for the information source, whether the input device information of the selector corresponding to the type-A device next to the selector on the selector chain table, such as the input device information of the selector corresponding to the type-B device, includes the information of the first device is continuously determined, and if the input device information of the selector corresponding to the type-B device does not include the information of the first device, the type-B device is unavailable for the information source; and sequentially determining whether the input equipment information of the selector corresponding to the other types of equipment comprises the information of the first equipment or not until the selector of which the input equipment information comprises the information of the first equipment is determined.

S203, determining at least one output device corresponding to the first device according to the information of the first device and the output device information in the selector corresponding to the first device.
The television control method also can ensure the accuracy of the selector corresponding to the first equipment by determining the selector corresponding to the first equipment from the selectors corresponding to the multiple types of equipment, thereby ensuring the accuracy of at least one output equipment corresponding to the first equipment, further effectively ensuring the accuracy of the equipment required for sending the service data corresponding to the information source and effectively ensuring the transmission of the service data corresponding to the information source.
Optionally, the selector corresponding to the first device as described above includes: the state information of each output device corresponding to the first device and the multiplexing information of each output device corresponding to the first device.
As described above, in S102, selecting one device from each output device corresponding to the first device as the second device corresponding to the source may include:
and determining at least one output device corresponding to the first device as an idle device or a reusable device as the second device according to the state information of each output device corresponding to the first device and the multiplexing information of each output device corresponding to the first device.
Specifically, the state information of each output device corresponding to the first device and the multiplexing information of each output device corresponding to the first device may be determined according to the selector corresponding to the first device. The state information of each output device corresponding to the first device may be usage state information of each output device corresponding to the first device, and the state information of each output device corresponding to the first device may be used to indicate whether each output device corresponding to the first device is occupied. The multiplexing information of each device can be used to indicate whether each output device corresponding to each first device is reusable. For example, if the output device B1 is determined to be unoccupied according to the status information of the output device B1 corresponding to the first device in the selector corresponding to the first device; the multiplexing information of output device B2 may determine that output device B2 is reusable, and output device B2 may be determined to be a reusable device, and thus, in the method, either output device B1 or output device B2 may be determined to be the second device.
In the selector corresponding to the first device, the occupied device in each output device corresponding to the first device can be represented by the occupied identifier corresponding to the device. The occupation identifier corresponding to the device may be an occupation identifier corresponding to the link identifier.

The selector of fig. 3 may be a selector corresponding to the first type of device.
If the first device is the input device 1 in the selector of fig. 3, the output devices corresponding to the input device 1 include the output device 1, the output device 2, and the output device 3. According to the state information of each output device corresponding to the input device 1 and the multiplexing information of each output device corresponding to the input device 1 in the selector, the multiplexing device corresponding to the input device 1, such as the output device 2 in fig. 3, is determined as the second device.
The state information of the output device 1 corresponding to the input device 1 in the selector in fig. 3 may be identified by an occupation number, and the occupation identification may be an occupation identification corresponding to the link identification. The link identifier may be a link corresponding to the input device 1 and the output device 1.
The corresponding relationship between the link identifier and the occupation identifier may be stored in a form of a table, or may be stored in other forms such as a database, a data diagram, and the like, for example, and the application is not limited thereto. The correspondence between the link identifier and the occupancy identifier is exemplified in the form of a table as follows. Table 1 is a table of correspondence between the link identifier and the occupancy identifier in the second embodiment of the present invention.

TABLE 1
With reference to fig. 3, in the selector corresponding to the first device, the state information of the output device 1 corresponding to the input device 1 is occupied, if the state information of the output device 1 corresponding to the input device 1 can be represented by an occupied identifier 2005, it can be determined from the table 1 that the link identifier corresponding to the occupied identifier is 2005, then the output device 1 corresponding to the input device 1 is occupied, and the link identifier of the link corresponding to the input device 1 and the output device 1 is 1005.
The method for controlling the television can determine each device corresponding to the information source according to the selector corresponding to the device, so that if a device is added to the television, the device, the state of the device, multiplexing information and the like can be added to the selector which takes the device as an input device and/or the device as an output device, or a selector added to the similar device can be inserted into a selection linked list of the television.
The following is exemplified by a selector using this type of device as an input device, and by adding each piece of information of this type of device as an output device, respectively. Fig. 4a is a schematic structural diagram of a selector added with a device in a selector serving as an input device according to a second embodiment of the present invention. Fig. 4b is a schematic structural diagram of a selector after devices are added to the selector serving as an output device in the second embodiment of the present invention. As shown in fig. 4a, after a device is added to the television, the device is added to the selector as an input device, which may be the input device 4 in the selector as an input device. As shown in fig. 4b, after the device is added to the television, the method further needs to add the device to the selector as the output device, which may be the output device 4 in the selector as the output device.
The television control method can add the information of the equipment in the selector of the equipment as the input equipment and/or the equipment as the output equipment under the condition that the equipment is added in the television, and can also insert the selector added for the similar equipment in the selection chain table of the television, thereby being convenient for the system expansion of the television and effectively improving the types of the information sources supported by the television and the types of the multimedia services of the realized information sources.

The target output device corresponding to the information source may be determined according to the identifier of the information source and a preset corresponding relationship between the information source and the target output device. The target output device corresponding to the information source may be a target output device corresponding to the information source determined according to the identifier of the information source included in the service request corresponding to the information source or the service data corresponding to the information source after receiving the service request corresponding to the information source or the service data corresponding to the information source.
Optionally, in the above-described television control method, the method may further include:
and when the state of the equipment changes, receiving the state notification sent by the equipment, and updating the state information of the equipment in a selector of the equipment.
In particular, the device status change may be that the device controller corresponding to the device within the tv series has an event occurrence. When the device controller corresponding to the device has an event occurrence, in the method, all links associated with the device can be traversed through the device controller corresponding to the device, the event including each link identifier is sequentially sent to a scheduling module of the television, a callback interface corresponding to each link is determined through the scheduling module according to each link identifier, a callback function corresponding to the callback interface is called through the scheduling module, a state query request is sent to the device, and then a state notification sent by the device through the device controller of the device is received. In the method, after the scheduling module calls the callback function corresponding to the callback interface, the television also sends an event notification to the application module through the scheduling module.
In the method, after a first device for sending the service data corresponding to the information source and a second device for receiving the service data corresponding to the information source are determined, a link corresponding to the first device to the second device is established. After the link is created, an interface corresponding to the link may be established, and the interface corresponding to the link may include: the control interface corresponding to the link and the callback interface corresponding to the link. The Interface corresponding to the link may be a Program Interface corresponding to the link, such as an Application Program Interface (API).
In the television control method, a control command comprising the link identifier can be sent to a scheduling module through an application module, a control interface corresponding to the control command comprising the link identifier is determined through the scheduling module according to the link identifier and a corresponding relation table of the link identifier and the interface, and then the control command is sent to each device on a link corresponding to the link identifier by calling a control function corresponding to the control interface.
In the television control method, when an event occurs, all links associated with the equipment are traversed by the equipment controller corresponding to the equipment in the television, the event including each link identifier is sequentially sent to the scheduling module, a callback interface corresponding to each link is determined by the scheduling module according to each link identifier, a callback function corresponding to the callback interface is called by the scheduling module, and an event notification is sent to the application module by the scheduling module.
The corresponding relationship between the link and the interface may be stored in a form of a table, or may be stored in other forms such as a database, a data chart, and the like, which is not limited in this application. The correspondence relationship between the link and the interface is exemplified in the form of a table as follows. Table 2 is a table of correspondence between link identifiers and interfaces in the second embodiment of the present invention.
