Problems solved by technology

[0005] The purpose of the present invention is to provide a method for starting and running a TV. By storing the TV program in an external memory for calling when the TV starts, it overcomes the difficulty of traditional TVs being limited by the storage capacity of their internal NAND Flash. Drawbacks of doing TV program extensions

Embodiment 1

[0035] Embodiment one, see figure 2 As shown, the TV set of this embodiment includes main components such as a CPU, a memory, a memory storing a system boot program, a boot interface, and an external memory storing a TV program (hereinafter referred to as an external memory for starting). Wherein, the CPU can be integrated into the main chip of the TV set, and connected to the internal memory, the storage and the startup interface respectively. The memory preferably adopts non-volatile memory such as NOR Flash to store the system boot program, which is called and run by the CPU when the TV is powered on. The startup interface is preferably arranged on the TV casing for plugging in an external memory for startup. If there is only one interface that can be inserted into the external memory on the TV set, then this interface is set as the starting interface. If there are multiple interfaces that can be inserted into the external memory on the TV, the TV manufacturer can design...

Embodiment 2

[0042] Embodiment 2, this embodiment proposes the following TV start-up method for the design scheme of specifying a fixed interface on the TV as the start-up interface, see Figure 4 shown, including the following process:

[0043] S401. In the initial stage, power on and start up the TV set.

[0044] During this process, the power supply circuit inside the TV converts the external AC power supply into a low-voltage DC power supply to supply power for the equipment inside the TV that needs to be powered on during the startup phase, such as the CPU, memory and storage system on the TV motherboard. The storage of the boot program (this embodiment will be described below with NOR Flash as an example), etc., to ensure the smooth progress of the boot process.

[0045] S402, the CPU in the main chip runs the system boot program in the NOR Flash, and enters the boot phase.

[0046] S403. The CPU detects whether an external memory is plugged into the startup interface by running th...

Embodiment 3

[0052] Embodiment 3. In this embodiment, any interface that can be plugged into an external memory set on the TV can be used as a design scheme for starting the interface. The following method for starting and running the TV is proposed, see Figure 5 shown, including the following process:

[0053] S501. In the initial stage, power on and start up the TV set.

[0054] During this process, the power supply circuit inside the TV converts the external AC power supply into a low-voltage DC power supply to supply power for the equipment inside the TV that needs to be powered on during the startup phase, such as the CPU, memory and storage system on the TV motherboard. The storage of the boot program (this embodiment will be described below with NOR Flash as an example), etc., to ensure the smooth progress of the boot process.

[0055] S502. The CPU in the main chip runs the system boot program in the NOR Flash and enters the boot phase.

[0056] S503. Define a variable i, and as...

Abstract

The invention discloses a starting operation method for a television and the television. Program of the television is stored in an external memory, in addition, the external memory is plugged on a starting interface of the television when the television needs to be operated, and then, the following starting operation processes are executed: (1) running system guide program by a central processingunit (CPU) to enter a guide period after the television is turned on; (2) loading the television program stored in the external memory into an internal memory of the television by the CPU through using starting interface driving program compiled in the system guide program; and (3) running the television program in the television by the CPU to complete the starting process of the television. The television adopting the method provided by the invention has the advantages that because a television host machine is separated from equipment for storing the television program, the television program is not limited by the volume of internal storage devices of the television, more functions can be realized, and in addition, users can easily upgrade the television program through a computer or theexternal memory.

Description

technical field [0001] The invention belongs to the technical field of television receivers, and in particular relates to a method for starting and running a television and a television designed using the method. Background technique [0002] In a traditional TV receiver, at least the main chip, memory, NOR Flash and NAND Flash need to be installed inside. The connection relationship of these devices is as follows: figure 1 . Wherein, the main chip includes a CPU; the NOR Flash stores a system boot program; and the NAND Flash stores a TV program. Under normal circumstances, the storage capacity of NAND Flash is 128M or 256M, and the TV program needs to be compressed below this capacity to ensure the normal storage and subsequent normal operation of the program. After the TV is powered on, the CPU in the main chip runs the system boot program in the NOR Flash. The system boot program has a NAND Flash driver, and the boot program loads the TV program stored in the NAND Flash...
