The first step to get a fully functional product is the define the product features and see if they meet the standard requirements. A list of expected features from an IP based RDK-V Accelerator are listed at Product Specifications. SoC can use this as a guide while engineering the RDK SoC platform.
RDKM offers collaboration space for SoCs which would help SoCs to collaborate with OEM and RDK teams (as well as any 3rd party). RDKM collaboration zone includes features like (but not limited to) CMF facility to maintain build manifests as well as SoC/OEM specific code, SoC SDK artifact storage facility, JIRA & RDK Wiki spaces, integration with Test & Certification suites, monthly & release tagging and so on.
Once the product features are decided, the device engineering can be started. SoC needs to decide on the hardware layout that incorporates components to the target board. A sample expected hardware specification list as well as a sample flash layout is available at Product Engineering.
SoC can make use of the details available at SoC Platform Firmware to start developing a Yocto build to engineer the device firmware builds based on RDK Yocto build setup.
RDKM offers an in-house Test & certification suite that facilitates SoCs to get their Video Accelerator product certified as RDK Compliant device.
Certification program includes testing which validates the RDK stack on the device with defined test suite called as RDK Certification Test Suite. It is mandatory to go through this program in order to brand user's platform as RDK compliant product.
For details on the RDK Certification please refer: RDK Video Accelerator Certification
Below are the list of components that has a HAL layer implementation that needs to be ported by SoC vendors.
Device settings component is having a HAL interface to control device specific peripherals such as video port, audio port and display and front panel.
More details on HAL interface can be found here: Device Settings HAL Types & Public API DTCP HAL Interfaces.
Integrates the SoC provided DTCP library with DTCP/IP manager Interface implementation which manages source/sink DTCP/IP sessions and performs the encryption/decryption.
Hal Interface specification: DTCP HAL Interfaces
Contains SoC specific MOCA libraries, headers and MOCA profile codes.
API Details: TR69 Host Interface Handler
qamtunersrc is a push based gstreamer source plugin which tunes to the given service and provides the SPTS data.
Properties
Depends on platform specific libraries for tune, filtering, and pod functionalities.
Playersinkbin is a gstreamer bin element consisting of demux, decoder and sink elements. A template file gstplayersinkbin.c.template and gstplayersinkbin.h.template are provided as a reference for SoC implementation. SoC has to add details of platform specific plugins and implement the required properties expected out of them.
SDK Vendors should implement CEC driver interface API as specified in hdmi_cec_driver.h
HAL Interface Specificcation: HDMI-CEC HAL API's specification
Power, IR and DeepSleep modules are having SoC dependency. API's are specified in plat_power.h, plat_ir.h and deepSleepMgr.h
More details about api's can be found here
Contains functions for creating and handling native eglwindow. Hal api's are specified in westeros-gl.h
Wi-Fi Client HAL provides an interface (data structures and API) to interact with underlying Wi-Fi driver and enabling the client to be connected with an Access Point.
Hal API's are specified in wifi_client_hal.h. Doxygen Link: Wifi HAL API Specification
Set of Cryptographic API's Implementation, can be used to achieve all type of Cryptographic requirements from Premium App.
Media Pipeline Backend layer is a module in device layer which glues the media pipeline capabilities of the device to that of the IgnitionX.
As part of integrating Premium Apps as a native application on the RDK stack, the Premium Apps Video Porting (PVP) Layer needs to be implemented. The PVP Layer consists of the following modules:
Abstraction layer for third-party applications to get specific GStreamer values from the SoC pipeline.
Amazon assets are encrypted using Microsoft PlayReady. A robust implementation of the PlayReady must be provided for porting kit to decrypt assets.
Text-to-speech converts text into spoken voice output to help customers navigate the Prime Video application without seeing the screen. Text-to-speech is mandatory for the US region and optional in other regions.
ccReader module which does the closed caption decoding is having HAL dependency. API's are specified in ccDataReader.h
More details on HAL interface can be found here: closed Caption HAL API's
Graphics library porting for SoC.
AES Encryption and decryption of packets handled from DVRManager SoC Layer.
Porting of mediaframework involves porting of the following sub-modules:
Details about HAL API's that require porting is published as part of Doxygen Documentation activity in Mediaframework HAL API Specification.
Service Manager as such doesn't have an HAL part to be implemented, however it can have a platform part that extends/alters it's functionality with few of the legacy services such as Power management (deep sleep), Front panel control, and so on.
PlayReady and WideVine Open CDMi implementation - specific to platform.
