This system has the external interface that links to each other with video input, video output, remote control command and the screen display interface of television set respectively.
This system carries out video playback control by following flow process:
(1), when powering up, controller is carried out reset operation, with its inner memory zero clearing,
(2) with video encoder, Compress softwares shrinking chip, memory interface initialization, enter compressive state,
(3), in compression process, controller monitors and to have or not the infrared ray order that decompresses, and then enters next step if having, otherwise, continue to monitor that system then keeps compressive state always.
(4), controller is Video Decoder, Compress softwares shrinking chip, memory interface initialization, enters decompression states,
(5), in decompression process, controller monitors and to have or not infrared ray to cease and desist order and have or not the ED signal, if having, finishes decompression states, and enter next step, otherwise continue to monitor.
(6), controller monitors and to have or not the infrared ray compress order, if having, then enters step (2), otherwise, monitor having or not the order that decompresses, if having, then enter step (4), otherwise repeat this step.
The present invention adapts to the requirement of information age, provides a kind of new means for appreciating TV programme better and obtaining information from TV, has also increased new function for TV.Use video instant playback system of the present invention, people are when appreciating TV programme, and the dynamic menu that can will disappear is at any time as required reset, so that careful appreciation, digestion or the interested TV news of record people, advertisement and other information.Obviously, the video instant playback system that this television set carries is owing to the method that is far superior to carry out with video tape recorder recording playback easy and simple to handle, economical and practical, thereby also has more promotional value.
Fig. 1 is a video instant playback system block diagram of the present invention.
Fig. 2 is that compression, decompressed data stream flow to schematic diagram.
Fig. 3 is a video instant playback system external interface schematic diagram.
Fig. 4 is a video instant playback system software control schematic flow sheet.
Below with reference to accompanying drawing the preferred embodiments of the present invention are described.
Fig. 1 has provided block diagram of the present invention, by diagram, video instant playback system of the present invention comprises video encoder 1, Video Decoder 2, Compress softwares shrinking chip 3, memory 4, memory interface 5 and controller 6, above-mentioned each device is by controller 6 controls, and each device all can be selected commercially available integrated circuit (IC) chip for use according to the function design of system.Wherein, video encoder 1 preferred integrated circuit (IC) chip BT819 is used for analog video signal is become digital video signal.Video Decoder 2 preferred integrated circuit (IC) chip BT856 are used for digital video signal is converted to analog video signal.Video encoder, Video Decoder pass through I
2C bus bus links to each other with controller.The preferred ZR36060 of Compress softwares shrinking chip is used to finish the compression and decompression of digital signal, and it links to each other with controller with read-write and address wire by data wire.Memory is optional, and its effect is the data image signal of storing after compressing with dynamic memor DRAM or SDRAM commonly used on the computer, and memory links to each other by data wire, address wire and control line with the memory interface.The memory interface is actually a PLD, i.e. FPGA (Field Programmable Gate Array) device.Can require according to the sequential of system to work out.The memory interface links to each other with controller with data wire by holding wire.Described controller is the heart of playback system, and the operating process of whole playback all is to realize under the control of controller.Controller in the native system adopts microprocessor, can adopt the enough any single-chip microcomputers of resource, preferred KS88C8316 type single-chip microcomputer in this example.
