Providing frame packing type information for video coding
First Claim
1. A method of providing video data, the method comprising:
- receiving, by a server device, a packed frame of a representation of a plurality of representations of video data of multimedia content, wherein the packed frame comprises two frames corresponding to different views of a scene for three-dimensional playback, wherein the representations act as alternatives to each other and have different coding or rendering characteristics from each other, wherein each of the representations corresponds to a separate, respective bitstream, and wherein each of the representations includes a respective plurality of segments including coded video data, the segments comprising respective independently retrievable files;
providing, by the server device, a manifest file to a client device separate from the server device, wherein the manifest file indicates a frame packing arrangement for the packed frame, wherein the manifest file includes descriptive data for each of the representations, and wherein the manifest file is separate from the segments of the representations such that the manifest file does not include any coded video data;
receiving, by the server device, a request from the client device for at least a portion of one of the segments of one of the representations described by the manifest file; and
in response to the request, sending, by the server device, at least the portion of the one of the segments to the client device.

Abstract
This disclosure includes techniques for signaling characteristics of a representation of multimedia content at a representation layer, such as frame packing arrangement information for the representation. In one example, an apparatus for receiving video data includes a processing unit configured to receive information indicative of whether a bitstream includes a packed frame of video data, wherein the packed frame comprises two frames corresponding to different views of a scene for three-dimensional playback, and wherein the information is present in a representation layer external to a codec layer of the bitstream, automatically determine whether the apparatus is capable of decoding and rendering the bitstream based on an analysis of the received information and decoding and rendering capabilities of the device, and retrieve the bitstream when the processing unit determines that the device is capable of decoding and rendering the bitstream.
