摘要:
A computing device generates a file that comprises a track box that contains metadata for a track in the file. Media data for the track comprises a sequence of samples. Each of the samples is a video access unit of multi-layer video data. As part of generating the file, the computing device generates, in the file, an additional box that documents all of the samples containing at least one Intra Random Access Point (IRAP) picture.

A computing device generates a file that comprises a track box that contains metadata for a track in the file. Media data for the track comprises a sequence of samples, each of the samples being a video access unit of multi-layer video data. As part of generating the file, the computing device generates, in the file, a sub-sample information box that contains flags that specify a type of sub-sample information given in the sub-sample information box. When the flags have a particular value, a sub-sample corresponding to the sub-sample information box contains exactly one coded picture and zero or more non-Video Coding Layer (VCL) Network Abstraction Layer (NAL) units associated with the coded picture.

The present invention provides an easy to use web-based system for enabling multiple-user social browsing of underlying video/DEVSA media content. A plurality of user interfaces are employed linked with one or more underlying programming modules and controlling algorithms. A data model is similarly supported and used for managing complex social commenting and details regarding a particular video set of interest. An interest intensity measurement and mapping system and mode are provided for increased use.
摘要:
Technologies are generally described for mitigating or eliminating the effects from data loss. In an example, a data transmission system may be configured to send a data stream to a receiving device over a first data transmission path. The data transmission system may also be configured to send data representing key frames included in the data stream to a redundancy transmission device over a second data transmission path. The redundancy transmission device may be configured to transmit key frames to the receiving device in response to a loss of data.

The invention relates to a method (10) in a streaming client (1) for handling video streaming data. The method (10) comprises: receiving (11), decoding (12) and buffering (13) video streaming data comprising frames of image data; displaying (14) the frames of image data on a display (40) of the streaming client (1); receiving (15) an input requesting a pause in the reception of video streaming data; selecting (16), among decoded frames of image data, an optimal frame of image data; continuing (17) displaying frames of image data available in a buffer (45) of the streaming client 1 until the selected optimal frame of image data is encountered; and displaying (18) the selected optimal frame of image data as a still picture on the display (40) of the streaming client (1). The invention also encompasses a streaming client (1), computer program (51) and computer program products (50).
摘要:
디지털 방송 시스템에서 비디오 스트림의 패킷화 방법 및 장치가 제공된다. 상기 패킷화 장치는 부호화된 비디오 스트림을 프레임의 종류에 따라 분류하는 비디오 프레임 체크 블록, 상기 분류된 각 프레임 별로 패킷 헤더를 설정하는 헤더 설정 블록, 및 상기 설정된 패킷 헤더를 기반으로 비디오 프레임을 패킷화하는 패킷화 블록을 포함한다. 상기 프레임의 종류는 I(Intra-coded) 프레임, P(Predicted) 프레임 및 B(Bi-predictive) 프레임 중 어느 하나일 수 있다. 본 발명에 의해 디지털 방송 스트림을 효율적으로 패킷화함으로써 기존의 동기 패킷화로 인한 오버헤드(overhead)를 줄일 수 있으며, 이에 따라 대역폭을 효율적으로 사용할 수 있다.
