Script-based video rendering

摘要

Systems and methods are provided for cross-platform rendering of video content on a plurality of different user-computing platform types. A script is transmitted to the user-computing platform and is interpreted by an application program to: decode a first type of encoded video data into first decoded video data; render the first decoded video data; determine a rate at which the first type of encoded video data is being received; and, in dependence on the determined rate, to perform at least one of: transmitting a request to receive a second type of encoded video data; modifying a characteristic of the decoding of the first type of encoded video data; and modifying a characteristic of the rendering of the first decoded video data.

1. A method performed by a computer system for rendering video content on a user-computing platform that is one type of a plurality of different user-computing platform types, the method comprising:
transmitting a script to the user-computing platform, the script configured to be interpreted by an application program operating on any one of the plurality of user-computing platform types and further configured to cause the script to be interpreted by the application program to:
decode a first type of encoded video data embodying the video content and received at the user-computing platform into first decoded video data comprising one or more first frame images;render the first decoded video data by displaying the one or more first frame images;determine a rate at which the first type of encoded video data is being received by the user-computing platform and perform at least one of:
transmitting a request to receive a second type of encoded video data embodying the video content, in dependence on the determined rate;modifying a characteristic of the decoding of the first type of encoded video data, in dependence on the determined rate; andmodifying a characteristic of the displaying of the one or more first frame images, in dependence on the determined rate; the script is further configured to cause the script to be interpreted by the application program to modify the characteristic of the decoding of the first type of encoded video data in dependence on the determined rate.
