The invention also discloses a corresponding device for decrypting and encrypting data by a Gstreamer. According to the method and the device, the downloaded encrypted data can be normally played in the pipeline, the decryption of the encrypted data is realized, and the pipeline can normally play the encrypted data.

The invention discloses a method and a device for extracting SPS (standard positioning services) and PPS (precise positioning services) from H264 frames and aims to transmit video description information to a remote teaching opposite terminal before video transmission, thus the terminal can normally play a video. The method includes: from the start of the H264 frames, determining the number N of NAL (network abstract layer) units and the start of each NAL unit according to synchronous codes; according to the start of each NAL unit, traversing NAL headers of the NAL units; according to the information of the NAL headers of the NAL units, locating the NAL units in an SPS (sequence parameter set) and a PPS (picture parameter set); according to the positions of the NAL units in the SPS and the PPS, storing SPS data and PPS data in a first buffer and a second buffer, respectively. The method allows the video from the opposite terminal to be normally decoded and played during remote teaching.

The invention discloses a system for encryption authorization and management of ground programs of a set top box. The aim of encryption authorization and management of ground programs is realized by a locking module in the internal of the set top box. The technical scheme is as follows: the system comprises a set top box and a management central server; the set top box is provided with a main board and a locking module; the locking module is connected with the main board and connected with the internet by a wireless network; the management central server sends downlink control signals to the set top box by a satellite or a ground wireless digital television network; the main board of the set top box sends the download control signals to the locking module; and the management central server directly communicates with the locking module in a two-way manner by the wireless network for passing the management information and the service information.

The invention provides temperature-sensing music tableware for children, relates to the technical field of articles for daily use, and aims to solve the problem that the prior art is unsanitary duringdining, children have adverse reaction due to the fact that food temperature is excessively high or excessively low, the dining manner is dull, children cannot be attracted to dine by themselves, parents need to consume a large amount time to feed the children, and the good dining habits of children cannot be cultured favorably. The tableware comprises a holding part and a tableware body and is characterized in that a connecting conversion part is arranged at one end of the holding part, a cavity for accommodating a lamp, a sound producer, a control chip and a power supply is arranged in theholding part, and the lamp, the sound producer and the control chip are electrically connected with the power supply; the lamp and the sound producer are controlled through the control chip; the tableware body is connected to the connecting conversion part of the holding part, a temperature sensor is arranged in the tableware body and electrically connected with the power supply, and the temperature sensor transmits sensed temperature information back to the control chip. The temperature-sensing music tableware is used for improving the bad dining habits of children to allow children to dine scientifically and sanitarily.

The invention relates to a method to process output signal according to the scanning method of television in disc device, which has high usable value. It includes the following steps: first, confirming the scanning method that the television supported according to the feedback signal form the television; second, processing video signal and output according to the confirmed scanning method. Thus, whichever the scanning method the television supports, it would be normally to play. No matter the signal process method of the disc device whether is interleaved-scanning or non-interlaced-scanning, the television would play video normally.

The invention relates to display equipment, a video data transmission method and a storage medium, and relates to the technical field of display. The display apparatus includes a controller configured to: acquire first video data; under the condition that the buffer data in the video buffer queue reaches the first preset buffer capacity of the video buffer queue and the buffer data in the target buffer queue does not reach the second preset buffer capacity of the target buffer queue, setting the first preset buffer capacity of the video buffer queue as a third preset buffer capacity, setting the second preset buffer capacity of the target buffer queue as a fourth preset buffer capacity; storing the first video data into a first buffer queue; the third preset buffering capacity is increased by a preset amount compared with the first preset buffering capacity, the fourth preset threshold is reduced by the preset amount compared with the second preset threshold, and the target buffering queue is any queue in other buffering queues. The embodiment of the invention is used for solving the problem of playing lagging.

The invention discloses a video processing method and device, and a computer storage medium. The video processing method comprises the steps of obtaining a first video resolution of an access controldevice and a second video resolution of a terminal device; arranging a local coding rectangular area in the center of an access control video of the access control equipment, and the rectangular height of the local coding rectangular area is the product of the ratio of the second vertical resolution to the second horizontal resolution of the second video resolution and the first horizontal resolution of the first video resolution; and sending the video data of the access control video in the local coding rectangular area to the terminal equipment, so that the terminal equipment displays the access control video corresponding to the video data of the local coding rectangular area.
