The invention relates to an article for daily use, namely an effect-enhancing and energy-saving frame of a cooking cover. The effect-enhancing and energy-saving frame is characterized in that a bracket (1) can be arranged on a cover head (6), and is connected with a plurality of vertical guide rods (2); and when the bracket (2) is arranged on the cover head (6), the lower ends of the guide rods (2) are close to the cover head (6), and the upper ends thereof can be jointed with the bottom part of a heated container (7). As the plurality of guide rods are arranged between the cover head and a container, under the premise that the gap of the container and the cover head is not changed, the container is connected with the cover head; under the premise that the size of the container and the cover head is not changed, the heated area of the container is increased, the heat-absorbing and heat-storing capabilities of the container are improved, therefore, the heat efficiency of fuel is obviously improved and the energy-saving and time-saving effects are achieved; in addition, the effect-enhancing and energy-saving frame of the cooking cover is characterized by simple structure, low manufacturing cost and convenient use and the like and is a revolutionary improvement for the traditional cooking cover.

The invention discloses a fast information embedding method for MP4 video code stream. As the currently popular video format MP4, its internal video coding standard is H.264; the format of H.264 code stream data has been fully examined, and a A simple, fast and effective code stream information hiding method, device, electronic device and storage device.

The invention provides a metal-finger plugging board and a manufacturing method thereof. The metal-finger plugging board comprises a main board body having a circuit board layer and a metal finger arranged at one side of the main board body. The metal finger is connected with the circuit board layer electrically by a top finger wiring layer and a bottom finger wiring layer opposite to the top finger wiring layer. The thickness between the top of the top finger wiring layer and the bottom of the bottom finger wiring layer is less than the thickness of the main board body along the lamination direction of the circuit board layer of the main board body. According to the invention, the design concept of the metal-finger plugging board enables the limitation of the conventional way to be broken through; and the traditional way of arranging the top finger wiring layer and the bottom finger wiring layer of the plugging head of the metal finger at positions, approaching the board edges, of the top surface and the bottom surface of the circuit board layer is changed. Therefore, the structure of the metal-finger plugging board is changed and the process for producing the metal-finger plugging board is changed. With the metal-finger plugging board, the function extending demand can be satisfied; the universality is high; and the production cost is not increased substantially.
