A method comprising: requesting, by a client, an independently coded first representation of a video content component from a server; receiving and playing a first set of data units of the independently coded first representation; requesting a second set of data units of a second representation, said second set of data units being dependently coded on one Receive and play a first set of data units of or more requested or buffered data units of the first set; and requesting a third set of independently coded data units of a third representation.

Methods and systems for storage and playback of broadcast media received via a local digital video recording (DVR) system. The system includes the DVR system configured to receive the broadcast media and upload the broadcast media to a storage server over a network. The DVR system divides the broadcast media content into blocks and assigns a unique block ID to each block based on the block data. Prior to uploading each block to the storage server, the unique block ID is sent to the storage server, which only uploads and stored the block if a duplicate block has not already been stored on the storage device, minimizing network demand. A transcoding server coupled to the storage server transcodes the broadcast media content for streaming over the network.

The present disclosure relates to an image processing device and an image processing method for generating a celestial sphere image such that the pixels near the poles of the sphere are kept from increasing in density when the image is mapped to the sphere surface.

An encoder encodes, with respect to an omnidirectional image generated by equidistant cylindrical projection to include a top image, a middle image, and a bottom image in a vertical direction, the middle image into an encoded stream at a high resolution, and the top image and the bottom image into encoded streams at a resolution lower than the high resolution. This disclosure is applicable to image display systems, among others.

The present disclosure relates to an image processing device and an image processing method for instantaneously displaying an image of a user's field of view.

An encoder encodes a celestial sphere image of a cube formed by images of multiple planes generated from omnidirectional images, the encoding being performed plane by plane at a high resolution, to generate a high-resolution encoded stream corresponding to each of the planes. The encoder further encodes, at a low resolution, the celestial sphere image to generate a low-resolution encoded stream. The present disclosure may be applied, for example, to image display systems that generate a celestial sphere image so as to display an image of the user's field of view derived therefrom.

A multimedia redirection method comprising receiving, by a server, a hardware decoding capability sent by a client, where the hardware decoding capability is a hardware decoding capability that is in a video hardware acceleration specification and that is converted from a hardware decoding capability of a non-Windows operating system by the client; restoring, by the server, video data to a video code stream of a standard encoding format after receiving the hardware decoding capability; and sending, by the server, the video code stream to the client for decoding and display.

A cloud recording system, a cloud recording server, and a cloud recording method are provided. The cloud recording system includes an image source device, a recording device, and a remote storage device. The image source device provides an audiovisual streaming data. The recording device is used for receiving the audiovisual streaming data. The recording device stores at least one recording time parameter and includes a capture unit and a conversion unit. The capture unit is used for capturing a partial audiovisual streaming data in accordance with the recording time parameter. The conversion unit is used for converting the partial audiovisual streaming data into a captured file. The recording device is configured to transmit the captured file to the external of the recording device. The remote storage device is connected to the recording device and is used for receiving and keeping the captured file.

The playback of video content upon a display is enhanced through the unobtrusive presentation of extrinsic data upon the same display. A video content feature is rendered on a display. A quantity of extrinsic data relevant to a current time in the video content feature is determined based at least in part on viewing history of a user. A graphical element presenting at least a portion of the extrinsic data is rendered on the display while the video content feature is also being rendered on the display.
