How to Use OSD Skin Editor with DVBViewer Pro 3.9.x+

OSD Skin Editor for DVBViewer Pro 3.9.x+ — Create Custom On‑Screen SkinsCreating a custom OSD (On‑Screen Display) skin for DVBViewer Pro 3.9.x+ lets you transform the visual identity of your TV interface — from menus, channel lists and EPG displays to status bars and notifications. This article covers what the OSD Skin Editor is, why you’d use it, how the skin system in DVBViewer Pro works, a step‑by‑step workflow for designing a skin, technical details and tips, plus troubleshooting and distribution advice.

What is the OSD Skin Editor?

The OSD Skin Editor is a toolset and file format used by DVBViewer Pro to define the look and layout of all on‑screen elements. A skin controls colors, fonts, spacing, element positions, images, and dynamic behavior (for example highlighting the current selection, showing progress bars, or animating transitions). For DVBViewer Pro 3.9.x+ the skin engine supports modern features such as alpha transparency, scaled bitmaps, and conditional element visibility, enabling rich, polished interfaces.

Why create a custom skin?

• Personalize the viewing experience to match your desktop or media center theme.
• Improve legibility for large screens or unique display setups.
• Optimize layout for specific resolutions, aspect ratios, or remote control ergonomics.
• Brand a shared system (e.g., for a hotel, bar, or demo station).
• Learn UI design applied to embedded media applications.

How DVBViewer Pro skins are structured

Skins for DVBViewer Pro are typically composed of:

• A central skin definition file (usually XML or an INI‑style format depending on version) that declares elements, layouts, and resource references.
• Image assets (PNG, BMP) for backgrounds, icons, and decorative elements. PNG with alpha is commonly used for smooth edges.
• Font declarations (system fonts or bundled TTF) and color definitions.
• Optional scripts or rules (in supported versions) to control conditional visibility and element behavior.

Key element types:

• Windows/panels: named containers that can contain other elements.
• Labels/text: static or dynamic text fields (channel name, time, EPG description).
• Buttons and entries: selectable controls with different visual states (normal, hover, selected).
• Progress bars and meters: for volume, recording progress, or buffering.
• Lists and grids: for channel lists and EPG listings with per‑row templates.

Designing a skin — step‑by‑step workflow

1. Plan your layout

   • Determine which screens you’ll redesign (main OSD, channel list, EPG, volume overlay, subtitles, etc.).
   • Sketch wireframes for each screen at your target resolution(s) (e.g., 1920×1080, 3840×2160).
   • Decide on a visual language: flat, skeuomorphic, translucent glass, neon, minimal.

2. Choose assets and typography

   • Pick readable fonts for different sizes (EPG descriptions need legible small text).
   • Create or source icons that match visual style.
   • Prepare background images or panels with appropriate alpha channels.

3. Create image assets at proper scales

   • Export PNGs at 1x and 2x if you want to support HiDPI displays.
   • Use 9‑patch style or sliced backgrounds where supported to keep borders consistent across sizes.

4. Build the skin file

   • Start from a working sample skin bundled with DVBViewer Pro to learn naming conventions and element properties.
   • Define containers, elements, and data bindings (e.g., bind label text to current channel name).
   • Set states for interactive elements (normal, focused, selected). Include fallback values.

5. Test iteratively

   • Load the skin in DVBViewer Pro and test each screen.
   • Check different resolutions, languages (text-length), font scaling, and remote control navigation.
   • Verify performance — avoid very large image assets that slow rendering.

6. Polish animations and transitions

   • Use subtle fades, slide transitions, and highlight animations to improve perceived quality.
   • Make sure animations are not distracting and maintain responsiveness.

7. Package and document

   • Bundle the skin definition, images, and any font files into a ZIP or named folder.
   • Include an installation README with screenshots, supported DVBViewer Pro versions (3.9.x+), and credits.

Technical considerations and tips

• File formats: prefer PNG for images (alpha transparency). Use lossless compression for crisp GUI elements.
• Color and contrast: ensure sufficient contrast for readability on varied TV panels. Test with color blindness simulators if accessibility matters.
• Localization: design flexible containers to accommodate different text lengths; avoid hard‑coded pixel positions for variable text.
• Performance: minimize large full‑screen PNGs; use tiled or sliced assets where possible. Reduce number of overlapping semi‑transparent layers to improve rendering speed.
• Fonts: bundle fonts only if licensing allows. Otherwise use common system fonts and document requirements.
• Resolution handling: implement relative positioning and scalable assets so one skin can support multiple resolutions.
• Backups: keep versioned copies of your skin files as you iterate.

Common pitfalls and troubleshooting

• Elements misaligned on some resolutions: check anchoring and use relative coordinates rather than fixed pixel offsets where supported.
• Blurry assets on HiDPI displays: include higher‑resolution images (2x) and ensure the skin references them correctly.
• Incorrect state visuals (selected/hover): confirm state images are named and referenced properly and that the skin file defines the state transitions.
• Slow UI: profile by removing large or many semi‑transparent layers and checking image file sizes.
• Missing text or fonts: ensure font files are available or that system fallback fonts cover necessary glyphs for localized languages.

Example: simple channel list entry (conceptual)

• Container: entryRow
  • Background normal: row_bg.png
  • Background selected: row_bg_sel.png
  • Icon: channel_logo.png
  • Label title: binds to channel name (font: Sans 18pt, color #FFFFFF)
  • Label subtitle: binds to current program (font: Sans 13pt, color #CCCCCC)
  • Progress bar: binds to program progress (color: accent)

(Implementation details depend on DVBViewer Pro’s actual syntax — consult a sample skin file to match attribute names.)

Distributing and licensing your skin

• Choose a license: permissive (MIT/BSD), Attribution (CC BY), or share‑alike (CC BY‑SA). If you include third‑party icons or fonts, follow their licenses.
• Provide clear installation steps and compatibility notes (explicitly state DVBViewer Pro 3.9.x+).
• Consider hosting on a GitHub repo or a community forum for feedback and issue tracking.

Resources and learning paths

• Inspect existing skins bundled with DVBViewer Pro to learn structure and best practices.
• Follow UI design basics: contrast, hierarchy, spacing, and alignment.
• Use image editing tools (Photoshop, GIMP, Affinity) and vector tools (Inkscape) for icon creation.
• Test on real displays to validate colors and legibility.

Creating an OSD skin for DVBViewer Pro 3.9.x+ is a rewarding mix of visual design and practical engineering. Start small — retheme a single overlay like volume or channel info — then expand to more screens once you’ve validated layout and performance.
