A computer-implemented system and method for streaming video from a server to a client are described. For example, a method according to one embodiment comprises: receiving at the server a request for video content from the client; in response to the request, determining the hardware/software configuration of the client; generating and/or selecting a temporary decoder based on the hardware/software configuration of the client; transmitting the temporary decoder to the client, the client installing the temporary decoder; encoding and streaming the requested video content from the server to the client, the video content being encoded based on the capabilities of the temporary decoder, the video content being decoded by the temporary decoder and rendered on the client; detecting that the client has ended the session with the server; and in response to detecting that the client has ended the session, temporarily disabling and/or removing the temporary decoder from the client.

An excellent display can be performed even when the frame rate changes dynamically at the reception side. When a switching portion at which a sequence of video streams to be transmitted is switched from a first sequence to a second sequence having a different frame rate from the first sequence is provided, display control information is inserted into at least encoded image data of a picture corresponding to the switching portion or a packet containing the encoded image data. A reception side performs display control of pictures using the display control information and implements an excellent display.

An electronic system that executes video streaming includes a video sender. The video sender converts video data into plural layers of bitstream packets with varied priorities for transmission. A bitstream packet with a lower layer of the plural layers of bitstream packets has a higher priority when being transmitted to a video receiver.

Streaming image data includes receiving a request for a video stream of a scene of a live event, generate a background portion of the scene, obtaining a model of an object in the scene, transmitting the background portion and the model of the object, generating a serialized data stream indicating a modification of the object from the model, and transmitting the serialized data stream for the object.

Techniques for on-demand issuance of private keys for encrypted video transmission are described. A video processing service of a provider network receives a request from a computing device outside the provider network to begin video processing of video data generated by a video source device outside the provider network. The video processing service sends instructions to a video encoding device associated with the video source device to establish the connection for video transmission. The video processing service sends an encryption key to the video encoding device, and sends a decryption key to a video decryption engine. Subsequently, the video processing service receives video data from the video source device, via the video encoding device.

Disclosed herein are a method and apparatus for generating/receiving a media file including NAL unit information and a method of transmitting a media file. A media file receiving method may comprise obtaining network abstraction layer (NAL) unit information of video data from a decoder configuration record in a media file and processing the video data based on the NAL unit information. The NAL unit information may comprise first information specifying a number of NAL units having a NAL unit type indicated in the decoder configuration record, for a stream to which the decoder configuration record is applied, and based on the indicated NAL unit type being a predetermined non-video coding layer (non-VCL) NAL unit type, obtaining of the first information may be skipped.
