Problems solved by technology

[0002] The existing traditional video recorders on the market are expensive, and the recorded format needs professional equipment to convert before it can be played on devices such as monitors that are not connected to traditional video recorders
[0003] The digital video recorders of the prior art have just emerged abroad, but they are all defined as home appliances, which are relatively large in size, not easy to carry around, and expensive
Some PMP products can realize the recording of TV programs, but they are all recorded through the output of the TV, and the video recording function cannot be realized without turning on the TV.

Description

technical field [0001] The invention relates to the technical field of digital video, in particular to a portable digital video recorder. Background technique [0002] The existing traditional video recorders on the market are expensive, and the recorded format requires professional equipment to convert before it can be played on devices such as monitors that are not connected to traditional video recorders. [0003] The digital video recorders of the prior art have just emerged abroad, but they are all defined as household electrical appliances, which are relatively large in size, are not easy to carry around, and are more expensive. Some PMP products can realize the recording of TV programs, but they are all recorded through the output of the TV, and cannot realize the video recording function without turning on the TV. Contents of the invention [0004] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to pro...
