To the present invention, the course of work that promptly has the digital television image signal processing apparatus of said structure is described as follows now.
By tuner (10) input analog signal or digital signal; And the signal of input is processed into the baseband signal that can handle by demodulator (20), and is input to analog to digital converter (30).
Above-mentioned analog to digital converter (30) becomes digital signal to the signal transformation of input, then this digital signal is input to picture signal handling part (40).By the control of CPU (50), be processed into the signal that can on picture, show then.
At the processed signal of picture signal handling part (40), will be imported into compression engine portion (60), and with user-selected fixed multiple compressed format store images.The picture signal that is stored will output to display part (not shown) or ancillary equipment (110) according to user's requirement.
That is, the signal selecting part (61) of compression engine portion (60) according to control signal, from digital difference signal, conversion process and the digital R.G.B signal of picture signal handling part (40) output, removes to select the signal that will compress.
The signal of being selected by signal selecting part (61) is imported into decoder (62), is transformed into the PCM data that can carry out Digital Signal Processing.The data that this is transformed will be imported into control part (63), and the signal of input is analyzed.
Be input to the signal of control part (63), will be by passing through I/O port (65), the signal of input by the format conversion algorithm that is stored in EEPROM (66), is transformed into the form that the user needs.
That is, the mpeg encoder (63a) by control part (63) becomes mpeg format with data conversion when going to encode.And, data conversion is become the picture quality of video disc, VHS, internet high bandwidth, internet low bandwidth etc. by user's appointment.
In addition, the AVI encoder (63b) by control part (63) is when encoding, can be by user's appointment, and utilize fixed compress mode, can go to change picture dimension, frame and data rate etc.
Actual A/V encoder (63c) by control part (63) is when encoding, and according to actual AV coded format, can change picture quality, picture dimension, data rate etc. by user's needs.
At this moment, EPLD portion (64) will regulate the timing of the various control signals between control part (63) and the external equipment.In EEPROM (66), there is driver, so that allow control part (63) become MPEG, AVI, actual A/V form to data conversion.Owing to can be stored into EEPROM (66) to new algorithm from the outside, so can upgrade to the content among the EEPROM (66).
Here, if the user wants that by I/O port (65) equipment output image signal to the periphery control part (63) is just to outside network device interface (100) output signal, so that the ancillary equipment that allows the user select can be selected so.The load mode selection portion (100a) of the outside network device interface (100) of received signal will go to select corresponding load mode according to the control signal of control part (63).
As mentioned above, digital television image signal processing apparatus of the present invention when as required the DID that stores outwards being transmitted, in order to improve transmission efficiency, should transmit the image that is compressed into multiple compress mode.
That is, the present invention is that the user passes through menu, selects required compress mode and transfer rate, goes store images then.This image will be sent to the outside by multiple outside network device interface (100).
And compression engine portion (60) will be with multiple mode compressed image.Outside network device interface (100) is controlled by user's requirement, so as to being compressed into various picture formats, is sent to internet, individual mobile communication terminal machine, PC etc.
