Graphics/Text Overlay over a Video stream is a feature where Images/Text can be overlaid on top of YUV (after Decoder and before Encoding) during the transcoding operation. The data to be overlaid can either be pre-downloaded to DSP or can be sent to DSP via an overlay server. The feature will support receiving both text and raw image/graphics data being received at the DSP from external server. Conversion of text content received from external source to YUV format will be done within the DSP. However in the case of raw graphics, media payload received at the DSP is expected to be in YUV format. The network encapsulation details will be based on the configuration provided to overlay channel by the application. The received data can then be alpha-blended on the Video Image.
RFC 4396 will be used to receive basic text content from the overlay server. The first phase of the implementation will be limited to receiving Type-1 unit of the RFC which will allow receipt of text content. Additionally the text will be expected to be in UTF-8 format. Implementation does not have the text modifier support RFC 4175 will be used to receive raw graphics YUV image from the external server.
