    MPLAB® Harmony Help - Decoder Libraries MPLAB Harmony Integrated Software Framework v1.11 © 2013-2017 Microchip Technology Inc. All rights reserved. Decoder Libraries Help Decoder Libraries Help This section provides descriptions of the Decoder libraries that are available in MPLAB Harmony. © 2013-2017 Microchip Technology Inc. MPLAB Harmony v1.11 2 Decoder Libraries Help AAC Decoder Library Library Interface AAC Decoder Library This section describes the AAC Decoder Library. Introduction The AAC Decoder Library is available for the PIC32MX family of microcontrollers. Description The AAC Decoder Library is a premium product and is not included in the standard release of MPLAB Harmony and must be purchased separately. Refer to the Microchip Premium MPLAB Harmony Audio web page (www.microchip.com/pic32harmonypremiumaudio) for additional information. This AAC algorithm Non-Modifiable Binary Code is designed for 80 MHz or greater PIC32MX MCUs. Keep in mind, this code requires 62 MIPS peak 34 MIPS average performance, 61 KB Flash and 12 KB RAM without frame buffer memory for operation on the PIC32MX MCU. This product is the non-modifiable binary. A modifiable source-code version of this code is also available on Microchip Direct (SW320013-2). Users are responsible for licensing for their products through Via Licensing. Assembly Language Issue There is an assembly language issue in the AAC Decoder Library that misaligns the stack pointer. Contrary to the MIPS programming specification, this error is benign except when the application is built for a device with a hardware Floating Point Unit (FPU), such as the PIC32MZ EF family of devices. In this case, the sub-routine context-saving operations will produce an exception and stop the application.

The ADSP-21364 is a floating-point probability model [2]. The probability model is dynamic in processor optimized for professional audio applications. We exploit the architectural features of this processor to implement the sense that a particular distribution is decided based on the the decoder using floating point arithmetic. Since the SHARC audio content in that particular frame of data.

The larger the number of statistically different for significantly reducing memory requirement is presented. frames of data, larger will be the number of models used. Compressed-array-representations of tree structures are used to reduce the execution time of the critical section of the Naturally, the information regarding these models have to be code.

  • USING OMA DRM 2.0 PROTECTED CONTENT Ogg Vorbis Protected Audio Under Symbian OS
    USING OMA DRM 2.0 PROTECTED CONTENT Ogg Vorbis Protected Audio under Symbian OS Francisco Pimenta, Carlos Serrão ADETTI, ISCTE/DCTI, Av. das Forças Armadas, Edifício ISCTE, Lisboa, Portugal Keywords: OMA, DRM, Symbian OS, Ogg Vorbis, Security, Cryptography. Abstract: The lack of control inherent to digital content has been put on the spotlight by copyright infringement coupled with massive content distribution online (e.g., Peer-to-Peer). Digital Rights Management seems to be the solution to counter this problem advocating the use of cryptography and other related security mechanisms to protect digital content and to associate rights with it which determine how, when and by whom it can be consumed. The Open Mobile Alliance (OMA) specifies mobile service enablers in order to ensure interoperability throughout the mobile spectrum. As prominent mobile devices, Symbian OS smartphones offer an interesting platform for the demonstration of OMA DRM for the consumption of multimedia content. This article outlines the mechanisms enabling the protected consumption of the open and patent-free audio format (Ogg Vorbis Website), Ogg Vorbis using an OMA DRM 2.0 compliant audio player application running under Symbian OS (directed for mobile devices). 1 INTRODUCTION Symbian Operating System (OS) mobile phones are a compelling deployment platform for OMA The growing proliferation of multimedia digital DRM 2.0 as their usage and multimedia capabilities content throughout, virtually, every digital platform are on the rise. and system available today has produced a profound impact. Digital Rights Management (DRM) solutions aim 2 OMA DRM 2.0 OVERVIEW to enable content providers to assign and oversee usage permissions or rights for multimedia content The main focus for this document will be the OMA upon purchase/distribution with the aid of DRM Agent entity and in particular it’s content and cryptographic mechanisms.
