1. A method comprising:
- receiving, at a set top box (STB) device, a data stream comprising video content data and meta data, the meta data comprising a first indicator of a first display format for the video content data;
accessing, at the STB device, the first indicator from the data stream; and
processing, at the STB device in response to accessing the indicator, the video content data to generate a first display data having the first display format.

Abstract
A set top box (STB) device receives a data stream comprising video content data and meta data. The data stream can include, for example, an H.264-compliant data stream transmitted to the STB device via a packet-switched network, such as an Internet Protocol Television (IPTV) network. The meta data comprises an indicator of a display format for the video content data. The STB device accesses the indicator from the data stream and processes the video content data to generate a first display data having the first display format. The STB device can include a preset static display format configuration that is overridden by the STB device in response to accessing the indicator.

21. A method comprising:
-
receiving, at a set top box (STB) device, a data stream comprising encoded video content data and an Active Format Descriptor (AFD) value representing a display resolution for the encoded video data; decoding, at the STB device, the encoded video content data based on the AFD value to generate decoded video data having the display resolution; and providing the decoded video data for display at a display device connected to the STB device. - View Dependent Claims (22, 23)
