Abstract

The present invention relates to a digital television receiving device and screenshot method thereof, which comprises: an erasable programmable memory and a central processor, and is characterized in that: the invention also includes a screenshot module and a timer built-in or external-connected with the central processor; the erasable programmable memory stores a screenshot option; the screenshot option includes: starting conditions, interval time, record time and work channel; the screenshot module is used to collect the screen data of the current frame; the timer is used to time the interval time and the record time; the central processor is used to start the timer to start timing the interval time and the record time when starting conditions come into force, according to the screenshot option in the erasable programmable memory, and the screenshot module will be started when the interval time arrives during the record time. As the technical scheme of the present invention employs automatic screenshot at intervals, the requirement for hard disk space, transmission speed and performance of the machine is low so as to be suitable for the long-time record.

Description

technical field [0001] The invention relates to the field of household electrical appliances, and more specifically, to a digital TV receiving device and a screenshot method thereof. Background technique [0002] At present, digital TV receiving devices (such as digital TV sets, set-top boxes, computers, etc.) generally have a screenshot function. For example, digital TV sets have a PVR (Personal Video Recorder) function, which can record the current program on a built-in disk or an external disk. Therefore, The PVR function can solve the problem of complete audio and video recording, but it has high requirements for disk space, transmission speed, and machine performance. [0003] The application document whose publication number is CN101321231A discloses a method for intercepting any frame of picture being played, and displays it to the audience after processing, but this method can only intercept one frame of picture. [0004] To sum up, the screenshot devices and screen...
