SMPTE ST 296 – Television – 1280 x 720 Progressive Image Sample Structure – Analog and Digital Representation and Analog Interface (Revision of SMPTE 296M-2001)

This standard defines a family of progressive image sampling systems for the representation of stationary or moving two-dimensional images sampled temporally at a constant frame rate and having an image format of 1280 pixels by 720 lines and an aspect ratio of 16:9 as given in Table 1. All systems in the table have the common characteristic that all the samples gathered within a single temporal unit, a frame, shall be spatially contiguous and provide a complete description of that frame (Section 6). This standard specifies: R’G’B’ color encoding; R’G’B analog and digital representation; Y’P’BP’R color encoding, analog representation, and analog interface; and Y’C’BC’R color encoding and digital representation. A bit-parallel digital interface is incorporated by reference in Section 11. This standard specifies multiple frame rates (Table 1) in 8-bit and 10-bit systems. It is not necessary for an implementation to support all formats to be compliant with this standard. However, an implementation must state which of the system formats are supported.
