Описание (английский):

IEC 62315-1:2003 specifies requirements for digital television (DTV) monitors that use an uncompressed, baseband, digital video interface. These requirements apply to baseband, digital, video interfaces that use the VESA E-EDID Standard for the discovery of supported video formats. This standard also specifies the video formats to be supported by a DTV monitor. The timing requirements for 14 video formats are specified along with requirements for video format discovery. A mechanism allowing a video source to discover the preferred format of a DTV monitor is also described.

Overview

IEC 62315-1:2003 defines DTV profiles for uncompressed, baseband digital video interfaces used between video sources and digital television (DTV) monitors. The standard focuses on how a DTV monitor advertises supported formats and how a source discovers and selects the preferred video format using the VESA E-EDID discovery mechanism. It specifies the video formats and the timing requirements for 14 video formats, plus a discovery mechanism for preferred-format negotiation. The document also provides guidance on applying the profiles to interfaces such as DVI and OpenLDI.

Key topics and technical requirements

Mandatory and optional formats: Any conformant monitor must support 640×480p @ 60 Hz; HDTV monitors (16:9) must support either 1280×720p or 1920×1080i. Support for 720×480i and 720×576i is optional.

Timing specifications: Detailed waveform timing diagrams and parameters (horizontal/vertical timing, total lines, blanking intervals) are provided for multiple progressive and interlaced formats (see Clauses 6.x).

Format discovery: Uses VESA E-EDID and E-DDC structures to enumerate supported formats and includes an extension for additional detailed timing descriptors.

Colorimetry: Specifies colorimetry considerations keyed to common broadcast references (see Clause 7).

Interface application guidance: Informative annexes describe application to DVI (Annex A) and OpenLDI (Annex B), including sync and cabling considerations.

Interoperability note: Recommends implementing digital content protection for interoperability between devices.

Applications and who uses this standard

IEC 62315-1 is practical for:

Display and monitor manufacturers - to ensure DTV monitors advertise and support required DTV timing profiles and aspect ratios.

Set-top box, tuner and source-device designers - to implement correct output formats and EDID-based negotiation so HDTV/EDTV content displays correctly.

System integrators and AV installers - to select compatible source/display combinations and troubleshoot format negotiation.

Test labs and compliance engineers - to validate timing, E-EDID descriptors, and colorimetry against the standard.

Firmware and driver developers - to implement EDID parsing and preferred-format selection algorithms.

Practical benefits include reliable interoperability, fewer manual format switches, consistent display of SD/ED/HD content, and clear requirements for implementing uncompressed digital video links.
