Video playing method and apparatus, and electronic device
A video playing method, apparatus and electronic device. The method comprises: obtaining to-be-played video frames; inputting the obtained to-be-played video frames into a preset decoder, and decoding the to-be-played video frames by the preset decoder to obtain decoded to-be-played video frames; storing the decoded to-be-played video frames as texture data in a texture storage area of a graphic processing unit; determining, from the decoded to-be-played video frames stored in the texture storage area, a decoded to-be-played video frame that satisfies a rendering condition as a to-be-rendered video frame; rendering and the determined to-be-rendered video frames by the graphic processing unit and playing the rendered video frame. With the embodiments of the present application, rendering speed of a graphic processing unit (GPU) can be increased to a certain extent. Therefore, video playing performance of the electronic device can be improved.

Method and apparatus for secure transfer and playback of multimedia content
A method and apparatus for secure transfer and playback of multimedia content enables the secure transfer of multimedia content from a digital video recorder (DVR) to a personal computer (PC) and further to a handheld device. A DVR determines which devices on a Local Area Network (LAN) are authorized to share and/or retrieve content from the DVR. The DVR receives a connection request from a PC on the LAN, authorizes the connection request and establishes a secure connection between the DVR and the PC. Once the secure connection is established, the DVR receives a request for multimedia content from the PC, prepares the multimedia content for transfer and transfers the multimedia content to the PC.

Verifying the rendering of video content at client devices using trusted platform modules
Systems and methods for verifying the rendering of video content on information resources are provided herein. A server can transmit a video content element having a first bit stream corresponding to a predesignated frame to a client device. The client device can identify the first bit stream as corresponding to the predesignated frame. The client device can decode the first bit stream corresponding to the predesignated frame of the video content element to generate a second bit stream. The client device can transmit, to the server, a tracking message including the second bit stream. The server can compare the second bit stream included in the tracking message from the client device with a third bit stream maintained at a database. The server can determine that the video content element is rendered at the client device responsive to the second bit stream matching the third bit stream.

Method to identify video applications from encrypted over-the-top (OTT) data
Aspects of the subject disclosure may include, for example, a processing system that performs operations including collecting encrypted network traffic flow data from user interaction with an application, deriving a first set of traffic feature vectors from the encrypted network traffic flow data collected, training a machine learning algorithm on the first set of traffic feature vectors to classify each traffic feature vector in the first set of traffic feature vectors as associated with a type of the application or not associated with the type of the application, and classifying whether an encrypted network traffic flow as the type of the application by applying the machine learning algorithm to a traffic feature vector of the encrypted network traffic flow. Other embodiments are disclosed.

Light weight transport stream streaming protocol for live transcoding system
A robust, computationally-efficient and secure system is described for streaming content from a server to a client device via the Internet or another digital network. Various aspects relate to automated processes, systems and devices for securing a media stream with efficient yet effective digital cryptography. In particular, content may be transmitted in transport stream (TS) format in which all packets are encrypted (e.g., using a cipher block chain), in which control packets are exempted from encryption (e.g., using an electronic codebook), or in any other manner.
